As described in greater detail below, ultrasonic surgical instruments, RF electrosurgical instruments, and surgical cutting/stapling instruments (among other types of surgical instruments) may be constructed with modular parts such that parts can be readily replaced or otherwise changed by a user. For instance, such modularity may enable selection of different end effectors for different settings. In addition or in the alternative, replaceability may provide a dichotomy of reusable and disposable parts of a surgical instrument. In some settings (e.g., those where a handle assembly is re-used several times, etc.), it may be desirable to provide a mechanism for the quick and accurate exchange of disposable blade/tube assemblies being utilized in a reusable handle. Similarly, it may be desirable to facilitate the utilization of several disposable blade/tube assemblies during a single medical procedure or for several separate medical procedures.
While a variety of surgical instruments have been made and used, it is believed that no one prior to the inventors has made or used the invention described in the appended claims.
While the specification concludes with claims which particularly point out and distinctly claim this technology, it is believed this technology will be better understood from the following description of certain examples taken in conjunction with the accompanying drawings, in which like reference numerals identify the same elements and in which:
The drawings are not intended to be limiting in any way, and it is contemplated that various embodiments of the technology may be carried out in a variety of other ways, including those not necessarily depicted in the drawings. The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present technology, and together with the description serve to explain the principles of the technology; it being understood, however, that this technology is not limited to the precise arrangements shown.
The following description of certain examples of the technology should not be used to limit its scope. Other examples, features, aspects, embodiments, and advantages of the technology will become apparent to those skilled in the art from the following description, which is by way of illustration, one of the best modes contemplated for carrying out the technology. As will be realized, the technology described herein is capable of other different and obvious aspects, all without departing from the technology. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.
I. Surgical Instruments for Use With Disposable Blade/Tube Components Coupled to a Reusable Handle
In some versions, control module (12) and/or power source (14) are incorporated into a handpiece of surgical instrument (10), such that surgical instrument (10) is readily portable and “tethereless”. In some other versions, control module (12) and/or power source (14) are separate from surgical instrument (10), and are coupled with surgical instrument (10) via a cable. By way of example only, control module (12) and/or power source (14) may be provided through an ultrasonic generator unit as described in U.S. Pub. No. 2011/0087212, entitled “Surgical Generator for Ultrasonic and Electrosurgical Devices,” published Apr. 14, 2011, the disclosure of which is incorporated by reference herein. Still other various ways in which control module (12) and power source (14) may be provided will be apparent to those of ordinary skill in the art in view of the teachings herein.
End effector (16) is coupled to control module (12) and/or other components by another electrical connection (22). End effector (16) is configured to perform a desired function of surgical instrument (10). By way of example only, such function may include cauterizing tissue, ablating tissue, severing tissue, ultrasonically vibrating, stapling tissue, or any other desired task for surgical instrument (10). End effector (16) may thus include an active feature such as an ultrasonic blade, a pair of clamping jaws, a sharp knife, a staple driving assembly, a monopolar RF electrode, a pair of bipolar RF electrodes, a thermal heating element, and/or various other components. As will be described in greater detail below, end effector (16) may also be removable from surgical instrument (10) for servicing, testing, replacement, or any other purpose as will be apparent to one of ordinary skill in the art in view of the teachings herein. In some versions, end effector (16) is modular such that surgical instrument (10) may be used with different kinds of end effectors (e.g., as taught in U.S. Provisional Application Ser. No. 61/410,603, etc.). Various other configurations of end effector (16) and uses for end effector (16) will be apparent to those of ordinary skill in the art in view of the teachings herein.
Surgical instrument (10) of the present example includes a trigger (18) and a sensor (20), though it should be understood that such components are merely optional. Trigger (18) may include a variety of components and/or features, including but not limited to a pivoting squeeze trigger, one or more buttons, one or more knobs or dials, one or more sliders, etc. Trigger (18) is coupled to control module (12) and power source (14) by electrical connection (22). Trigger (18) may be configured to selectively provide power from power source (14) to end effector (16) (and/or to some other component of surgical instrument (10)) to activate surgical instrument (10) when performing a procedure. In some versions where control module (12) is omitted, trigger (18) simply serves as a switch to selectively complete a circuit between power source (14) and end effector (16). Sensor (20) is also coupled to control module (12) by an electrical connection (22) and may be configured to provide a variety of information to control module (12) during a procedure. By way of example only, such configurations may include sensing a temperature at end effector (16), sensing the impedance of tissue adjacent to end effector (16), determining the oscillation rate of end effector (16), etc. Data from sensor (20) may be processed by control module (12) to affect the delivery of power to end effector (16) (e.g., in a feedback loop, etc.). Various other configurations of sensor (20) and uses for sensor (20) will be apparent to those of ordinary skill in the art in view of the teachings herein. Of course, as with other components described herein, surgical instrument (10) may have more than one sensor (20), or sensor (20) may simply be omitted if desired.
Merely illustrative variations of surgical instrument (10) may take will be described in greater detail below. It should therefore be understood that any of the above teachings may be readily combined with any of the teachings below. It should also be understood that any of the teachings herein may be readily combined with any of the teachings in any of the references cited herein. Various suitable ways in which such teachings may be combined will be apparent to those of ordinary skill in the art in view of the teachings herein. All such modifications and variations are intended to be included within the scope of the claims.
II. Exemplary Surgical Instrument with Breech Style Coupling for Removable Shaft Assembly
Handle assembly (102) of the present example comprises a pistol grip (103), a pivoting trigger (105), and a pair of buttons (107). Pivoting trigger (105) is operable to selectively actuate a pivoting clamp pad of an end effector as will be described in greater detail below. Buttons (107) are operable to selectively activate a harmonic blade of the end effector as will also be described in greater detail below. For instance, one button (107) may activate the harmonic blade at a higher power level while the other button (107) may activate the harmonic blade at a lower power level. Handle assembly (102) also includes a transducer (108). Transducer (108) is coupled with cable (106) and comprises a plurality of piezoelectric elements that are configured to convert electrical power from cable (106) into ultrasonic vibrations. These vibrations are transmitted to a distal threaded member (109), which is configured to acoustically couple with a waveguide of shaft assembly (110) as will be described in greater detail below. An integral torque knob (140) is operable to rotate transducer (108) to secure the engagement between distal threaded member (109) and the waveguide of shaft assembly (110). Handle assembly (102) also includes a transverse bar (118) and a resilient locking tab (124) for engaging shaft assembly (112).
Shaft assembly (110) of the present example comprises a shaft (110) extending distally from a casing (113), which further includes an attachment hook (116). The distal end of shaft assembly (110) includes an end effector (not shown), which includes the pivoting clamp pad and harmonic blade referred to above. Examples of these components are taught in various references cited herein. For instance, a waveguide (not shown) may extend coaxially through shaft assembly (110) to acoustically couple the harmonic blade with distal threaded member (109) of transducer (108), thereby transmitting ultrasonic vibrations from transducer (108) to the harmonic blade. A secondary tube (not shown) is slidably and coaxially disposed about the waveguide, and is thus slidably and coaxially disposed within shaft (110). This secondary tube translates within shaft (110) to selectively pivot the clamp pad toward and away from the harmonic blade. The proximal end of the secondary tube is coupled with a force limiting mechanism (130), which is configured to engage a yoke (128) of handle assembly (102) as will be described in greater detail below. Force limiting mechanism (130) of shaft assembly (110) may comprise a wave spring mechanism, a double wave spring mechanism, and/or any other suitable structure. Yoke (128) is coupled with pivoting trigger (105), such that yoke (128) translates in response to trigger (105) pivoting toward and away from grip (103). This engagement thus provides pivoting of the clamp pad in response to pivoting of trigger (105).
To connect shaft assembly (110) to the handle assembly (102), the user places attachment hook (116) onto transverse bar (118) and rotates upwardly or clockwise the proximal end of shaft assembly (110) until locking detent (120) of shaft assembly (110) snaps into engagement with locking tab (124) of handle assembly (102). At this point, a groove (126) of force limiting mechanism (130) is received in yoke (128) of handle assembly (102). Movement of trigger (105) now causes corresponding motion in force limiting mechanism (130) of surgical shaft assembly (110), which in turn causes pivoting movement of the clamp pad in the end effector. The user then pushes torque knob (140) forward and rotates it so that distal threaded member (109) readily attaches to the proximal end of the waveguide of shaft assembly (110), acoustically coupling transducer assembly (108) to the waveguide of shaft assembly (110). In some versions, torque knob (140) includes features providing functionality similar to that of a torque wrench, whereby such features ensure ideal acoustic continuity by permitting the coupling to have sufficient torque while preventing the coupling from having too much torque. By way of example only, torque knob (140) may include features that provide two clicks when transducer assembly (108) is coupled to the waveguide with an appropriate amount of torque, thereby providing audible and/or tactile feedback to the user. It should also be understood that connector (106) may be coupled to torque knob (140) in a manner such that connector (106) rotates with torque knob (140). Alternatively, connector (106) may remain stationary as torque knob (140) and transducer (108) rotate. In such versions, connector (106) may be coupled with transducer (108) via a commutator, slip ring assembly, and/or other types of features. As another merely illustrative example, rotation knob (112) may be configured to provide such limiting of torque. As yet another merely illustrative example, a disposable torque wrench could couple transducer assembly (108) and surgical shaft assembly (110) to the distal end of handle assembly (102) in a conventional manner, as will be apparent to one of ordinary skill in the art in view of the teachings herein. Of course, the connection may alternatively be one that does not provide torque limiting.
It should also be understood that a cam or other feature may be provided to advance transducer assembly (108) toward shaft assembly (110) or vice versa, such that torque knob (140) need not necessarily be pushed forward to linearly engage torque assembly with shaft assembly (110). For instance, torque knob (140) may be coupled with a worm gear, rack and pinion system, and/or other type of feature that linearly drives transducer assembly (108) distally in response to rotation of torque knob (140). Such distal movement may be concomitant with rotation of transducer assembly (108). As another merely illustrative alternative, a mechanism may provide staged movement, such that rotation of torque knob (140) initially just translates transducer assembly (108) then just rotates transducer assembly (108) after transducer assembly (108) has been translated an appropriate distance.
As will be apparent to one of ordinary skill in the art in view of the teachings herein, the configuration of surgical instrument (100) provides for the selective coupling of a reusable or disposable shaft assembly (110) to disposable or reusable handle assembly (102). To replace a shaft assembly (110), the user may simply rotate torque knob (140) in the opposite direction to de-couple distal threaded member (109) from the waveguide of shaft assembly (110); then depress locking tab (124) to disengage detent (120); then rotate shaft assembly (110) downward to remove hook (116) from transverse bar (118). In some other versions, the casing (113) of shaft assembly (110) may be reusable with only the remaining portion of shaft assembly (110) needing to be selectively coupled to the disposable or reusable handle assembly (102). For instance, attachment hook (116) and transverse bar (118) may form a permanent hinge that would provide for the surgical shaft assembly (110) to open but stay connected to the disposable or reusable handle assembly (102). At this point, the user would remove shaft (112) and drop in another disposable or reusable shaft (112), rotate casing (113) into position and couple the shaft (112) to handle assembly (102). As another merely illustrative variation, the user may simply withdraw the waveguide and blade from shaft assembly (110) when shaft assembly (110) is rotated downward, without removing shaft assembly (110) from handle assembly (102), and slide another waveguide and blade into shaft assembly (110). Other suitable variations will be apparent to those of ordinary skill in the art in view of the teachings herein.
III. Exemplary Surgical Instrument with Removable Shaft Assembly Having Integral Pivot Bar
Handle assembly (204) of the present example comprises a pistol grip (203), a pivoting trigger (205), and a pair of buttons (216). Pivoting trigger (205) is operable to selectively actuate a pivoting clamp pad of an end effector as will be described in greater detail below. Buttons (216) are operable to selectively activate a harmonic blade of the end effector as will also be described in greater detail below. For instance, one button (216) may activate the harmonic blade at a higher power level while the other button (216) may activate the harmonic blade at a lower power level. Handle assembly (204) also includes a transducer (220). Transducer (220) is coupled with cable (202) and comprises a plurality of piezoelectric elements that are configured to convert electrical power from cable (202) into ultrasonic vibrations. These vibrations are transmitted to a distal threaded member (240), which is configured to acoustically couple with a waveguide of shaft assembly (214) as will be described in greater detail below. An integral torque knob (230) is operable to rotate transducer (220) to secure the engagement between distal threaded member (240) and the waveguide of shaft assembly (214). Handle assembly (204) also includes a receiving notch (238) and yoke (207) for engaging shaft assembly (214).
Shaft assembly (214) of the present example comprises a shaft (208) extending distally from a knob (222). The distal end of shaft assembly (214) includes an end effector (not shown), which includes the pivoting clamp pad and harmonic blade referred to above. Examples of these components are taught in various references cited herein. For instance, a waveguide (not shown) may extend coaxially through shaft assembly (214) to acoustically couple the harmonic blade with distal threaded member (240) of transducer (220), thereby transmitting ultrasonic vibrations from transducer (220) to the harmonic blade. A secondary tube (not shown) is slidably and coaxially disposed about the waveguide, and is thus slidably and coaxially disposed within shaft (208). This secondary tube translates within shaft (208) to selectively pivot the clamp pad toward and away from the harmonic blade. The proximal end of the secondary tube is coupled with a force limiting mechanism (236), which is configured to engage a yoke (207) of handle assembly (204) as will be described in greater detail below. Force limiting mechanism (236) of shaft assembly (214) may comprise a wave spring mechanism, a double wave spring mechanism, and/or any other suitable structure. Yoke (207) is coupled with pivoting trigger (205), such that yoke (207) translates in response to trigger (205) pivoting toward and away from grip (203). This engagement thus provides pivoting of the clamp pad in response to pivoting of trigger (205). Shaft assembly (214) also includes a pivot bar (224), which is removably received in notch (238) of handle assembly (204).
To connect shaft assembly (214) to transducer assembly (220), the user positions pivot bar (224) into receiving notch (238) and then utilizes pivot bar (224) to rotate shaft assembly (210) clockwise until force limiting mechanism (236) mates with yoke (207). In particular, yoke (207) encompasses groove (234) of force limiting mechanism (236). Movement of trigger (205) now causes corresponding motion in force limiting mechanism (236) of surgical shaft assembly (214), which in turn causes pivoting movement of the clamp pad in the end effector. After force limiting mechanism (236) is positioned in yoke (207), the user then manipulates torque knob (230) to couple distal threaded member (240) of transducer (220) with the proximal end of the waveguide of shaft assembly (214), acoustically coupling transducer assembly (220) to the waveguide of shaft assembly (214). As in surgical instrument (100), torque knob (230) may include features similar to that of a torque wrench, a separate torque wrench may be used, such features may be otherwise provided, or such features may simply be omitted. By way of example only, torque knob (230) may include features that provide two clicks when transducer assembly (220) is coupled to the waveguide with an appropriate amount of torque, thereby providing audible and/or tactile feedback to the user. It should also be understood that torque knob (230) may be pushed forward to drive transducer (220) toward shaft assembly (214) in some versions; or a cam or other feature may be provided to advance transducer assembly (220) toward shaft assembly (214) or vice versa. While not shown, some versions of handle assembly (204) may include an integral sliding cover that slides over the coupled proximal end of shaft assembly (214) and distal end of handle assembly (204), protecting the components therein from debris, etc., during use of surgical instrument. Alternatively a snap-on cap, shield, or other feature may be provided to cover these regions.
It should also be understood that a cam or other feature may be provided to advance transducer assembly (220) toward shaft assembly (214) or vice versa, such that torque knob (230) need not necessarily be pushed forward to linearly engage torque assembly with shaft assembly (214). For instance, torque knob (230) may be coupled with a worm gear, rack and pinion system, and/or other type of feature that linearly drives transducer assembly (220) distally in response to rotation of torque knob (230). Such distal movement may be concomitant with rotation of transducer assembly (220). As another merely illustrative alternative, a mechanism may provide staged movement, such that rotation of torque knob (230) initially just translates transducer assembly (220) then just rotates transducer assembly (220) after transducer assembly (220) has been translated an appropriate distance.
As will be apparent to one of ordinary skill in the art in view of the teachings herein, the configuration of surgical instrument (200) provides for the selective coupling of a reusable or disposable shaft assembly (214) to disposable or reusable handle assembly (204). By way of example only, if the blade of shaft assembly (214) and/or transducer (220) were to have an error during the set up because the torque was inadequate, handle assembly (204) and/or shaft assembly (214) could be replaced. To replace a shaft assembly (214), the user may simply rotate torque knob (230) in the opposite direction to de-couple distal threaded member (240) from the waveguide of shaft assembly (214); then rotate shaft assembly (214) downward to remove pivot bar (224) from notch (238). Other suitable variations will be apparent to those of ordinary skill in the art in view of the teachings herein.
IV. Exemplary Surgical Instruments with Drop-in Removable Shaft Assembly and Pivoting Cover
Handle assembly (304) of the present example comprises a pistol grip (303), a pivoting trigger (305), and a pair of buttons (316). Pivoting trigger (305) is operable to selectively actuate a pivoting clamp pad of an end effector as will be described in greater detail below. Buttons (316) are operable to selectively activate a harmonic blade of the end effector as will also be described in greater detail below. For instance, one button (316) may activate the harmonic blade at a higher power level while the other button (316) may activate the harmonic blade at a lower power level. Handle assembly (304) also includes a transducer (not shown). The transducer is coupled with cable (302) and comprises a plurality of piezoelectric elements that are configured to convert electrical power from cable (302) into ultrasonic vibrations. These vibrations are transmitted to a distal threaded member (not shown), which is configured to acoustically couple with a waveguide of shaft assembly (314) as will be described in greater detail below. An integral torque knob (330) is operable to rotate the transducer to secure the engagement between the distal threaded member and the waveguide of shaft assembly (314). Handle assembly (304) also includes a distal notch (338) and upper open portion (339) for receiving shaft assembly (314); as well as a yoke (not shown) and pivoting cover (350) for engaging shaft assembly (314). In this example, pivoting cover (350) pivots about an axis that is parallel to the longitudinal axis of shaft assembly (314).
Shaft assembly (314) of the present example comprises a shaft (308) extending distally from a knob (309). The distal end of shaft assembly (314) includes an end effector (not shown), which includes the pivoting clamp pad and harmonic blade referred to above. Examples of these components are taught in various references cited herein. For instance, a waveguide (not shown) may extend coaxially through shaft assembly (314) to acoustically couple the harmonic blade with the distal threaded member of the transducer of handle assembly (304), thereby transmitting ultrasonic vibrations from the transducer to the harmonic blade. A secondary tube (not shown) is slidably and coaxially disposed about the waveguide, and is thus slidably and coaxially disposed within shaft (308). This secondary tube translates within shaft (308) to selectively pivot the clamp pad toward and away from the harmonic blade. The proximal end of the secondary tube is coupled with a force limiting mechanism (336), which is configured to engage a yoke (not shown) of handle assembly (304) as will be described in greater detail below. Force limiting mechanism (336) of shaft assembly (314) may comprise a way spring mechanism, a double wave spring mechanism, and/or any other suitable structure. The yoke is coupled with pivoting trigger (305) as described elsewhere herein, such that the yoke translates in response to trigger (305) pivoting toward and away from grip (303). This engagement thus provides pivoting of the clamp pad in response to pivoting of trigger (305).
To connect shaft assembly (314) to handle assembly (304) and to the transducer assembly therein, the user positions the proximal portion of shaft assembly (314) in distal notch (338) and upper open portion (339) of handle assembly (304). In this example, the proximal portion of shaft assembly (314) includes all features located proximal to knob (309). The user then presses downwardly to seat force limiting mechanism (336) in the yoke of handle assembly (304), such that the yoke encompasses groove (334) of force limiting mechanism (336). Next, the user moves pivot cover (350) to a closed position. Movement of trigger (305) now causes corresponding motion in force limiting mechanism (336) of shaft assembly (314), which in turn causes pivoting movement of the clamp pad in the end effector. After force limiting mechanism (336) is positioned in the yoke, the user then manipulates torque knob (330) to couple the distal threaded member of the transducer in handle assembly (304) with the proximal end of the waveguide of shaft assembly (314), acoustically coupling the transducer assembly to the waveguide of shaft assembly (314). As in surgical instrument (100), torque knob (330) may include features similar to that of a torque wrench, a separate torque wrench may be used, such features may be otherwise provided, or such features may simply be omitted. By way of example only, torque knob (330) may include features that provide two clicks when the transducer is coupled to the waveguide with an appropriate amount of torque, thereby providing audible and/or tactile feedback to the user. It should also be understood that torque knob (330) may be pushed forward to drive the transducer toward shaft assembly (314) in some versions; or a cam, worm gear, rack and pinion, and/or other feature may be provided to advance the transducer assembly toward shaft assembly (314) or vice versa. Before or after the acoustic coupling is completed, the user pivots cover (350) closed to retain and/or protect the proximal end of shaft assembly (314).
As will be apparent to one of ordinary skill in the art in view of the teachings herein, the configuration of surgical instrument (300) provides for the selective coupling of a reusable or disposable shaft assembly (314) to disposable or reusable handle assembly (304). By way of example only, if the blade of shaft assembly (314) and/or the transducer were to have an error during the set up because the torque was inadequate, handle assembly (304) and/or shaft assembly (314) could be replaced. To replace a shaft assembly (314), the user may simply rotate torque knob (330) in the opposite direction to de-couple the distal threaded member of the transducer from the waveguide of shaft assembly (314), open cover (350, 351), then pull shaft assembly (314) in a transverse direction to remove from handle assembly (304). In the version shown in
Handle assembly (404) of the present example comprises a pistol grip (403), a pivoting trigger (405), and a pair of buttons (407). Pivoting trigger (405) is operable to selectively actuate a pivoting clamp pad of an end effector as will be described in greater detail below. Buttons (407) are operable to selectively activate a harmonic blade of the end effector as will also be described in greater detail below. For instance, one button (407) may activate the harmonic blade at a higher power level while the other button (407) may activate the harmonic blade at a lower power level. Handle assembly (404) also includes a transducer (not shown). The transducer is coupled with cable (409) and comprises a plurality of piezoelectric elements that are configured to convert electrical power from cable (409) into ultrasonic vibrations. These vibrations are transmitted to a distal threaded member (not shown), which is configured to acoustically couple with a waveguide of shaft assembly (402) as will be described in greater detail below. An integral torque knob (411) is operable to rotate the transducer to secure the engagement between the distal threaded member and the waveguide of shaft assembly (402). Handle assembly (404) also includes a recess (416) for receiving shaft assembly (402); as well as a yoke (408) and pivoting cover (410) for engaging shaft assembly (402). In this example, pivoting cover (410) pivots about an axis that is perpendicular to the longitudinal axis of shaft assembly (402).
Shaft assembly (402) of the present example comprises a shaft (420) extending distally from a knob (422). The distal end of shaft assembly (402) includes an end effector (not shown), which includes the pivoting clamp pad and harmonic blade referred to above. Examples of these components are taught in various references cited herein. For instance, a waveguide (not shown) may extend coaxially through shaft assembly (402) to acoustically couple the harmonic blade with the distal threaded member of the transducer of handle assembly (404), thereby transmitting ultrasonic vibrations from the transducer to the harmonic blade. A secondary tube (not shown) is slidably and coaxially disposed about the waveguide, and is thus slidably and coaxially disposed within shaft (420). This secondary tube translates within shaft (420) to selectively pivot the clamp pad toward and away from the harmonic blade. The proximal end of the secondary tube is coupled with a force limiting mechanism (424), which is configured to engage yoke (408) of handle assembly (404) as will be described in greater detail below. Force limiting mechanism (424) of shaft assembly (402) may comprise a way spring mechanism, a double wave spring mechanism, and/or any other suitable structure. The yoke is coupled with pivoting trigger (405) as described elsewhere herein, such that the yoke translates in response to trigger (405) pivoting toward and away from grip (403). This engagement thus provides pivoting of the clamp pad in response to pivoting of trigger (405).
To connect shaft assembly (402) to handle assembly (404) and to the transducer assembly therein, and with cover (410) pivoted to an open position, the user positions the proximal portion of shaft assembly (402) in recess (416) of handle assembly (404). In this example, the proximal portion of shaft assembly (402) includes all features located proximal to knob (422). The user then presses downwardly to seat force limiting mechanism (424) in yoke (408) of handle assembly (404), such that yoke (408) encompasses groove (426) of force limiting mechanism (424). Movement of trigger (405) now causes corresponding motion in force limiting mechanism (424) of shaft assembly (314), which in turn causes pivoting movement of the clamp pad in the end effector. After force limiting mechanism (424) is positioned in yoke (416), the user then manipulates torque knob (411) to couple the distal threaded member of the transducer in handle assembly (404) with the proximal end of the waveguide of shaft assembly (402), acoustically coupling the transducer assembly to the waveguide of shaft assembly (402). As in surgical instrument (100), torque knob (411) may include features similar to that of a torque wrench, a separate torque wrench may be used, such features may be otherwise provided, or such features may simply be omitted. By way of example only, torque knob (411) may include features that provide two clicks when the transducer is coupled to the waveguide with an appropriate amount of torque, thereby providing audible and/or tactile feedback to the user. It should also be understood that torque knob (411) may be pushed forward to drive the transducer toward shaft assembly (402) in some versions; or a cam, worm gear, rack and pinion, and/or other feature may be provided to advance the transducer assembly toward shaft assembly (402) or vice versa.
In some versions, the user pivots cover (410) closed to retain and/or protect the proximal end of shaft assembly (402) before or after the transducer is coupled with the waveguide of shaft assembly (402). In some other versions, torque knob (411) is further configured to close cover (410) while torque knob (411) couples the transducer with the waveguide of shaft assembly (402), such that the two acts are performed substantially simultaneously. In addition, some versions of torque knob (411) are configured to cover hinge (412) of cover (410) upon coupling of the transducer with the waveguide of shaft assembly (402). For instance, a cam or other feature may advance torque knob (411) distally when torque knob (411) is rotated sufficiently to couple the transducer with the waveguide of shaft assembly (402). Positioning at least part of torque knob (411) over hinge (412) may prevent cover (410) from being opened while the transducer is coupled to the waveguide of shaft assembly (402). Other suitable variations will be apparent to those of ordinary skill in the art in view of the teachings herein.
VII. Exemplary Handle Assembly Providing Separation of Mechanical Features from Electrical Features
In some instances, it may be desirable to provide modularity of mechanical components of a surgical instrument (10) in an integral fashion with a shaft assembly. In other words, it may be desirable for a shaft assembly and all related mechanical components to be readily removable from non-mechanical components of a surgical instrument (10). In some such versions, the non-mechanical components of the surgical instrument (10) may include electrical components such as a portable power source (e.g., battery, etc.), a control module (e.g., one or more printed circuit boards with integral components, etc.), and/or other types of components. In some such versions, the non-mechanical components of the surgical instrument (10) may be provided as a re-usable unit and/or re-usable components; while the mechanical components may be provided as a replaceable and/or disposable unit (and/or as replaceable components and/or replaceable components).
Second module (2120) of the present example includes a pistol grip (2122) and houses a battery (not shown) and a control module (not shown). First module (2110) is operable to couple with second module (2120) through a pivotal coupling (2130). For instance, modules (2110, 2120) may first be joined at coupling (2130) as shown in
In some versions, second module (2120) is provided as a reusable component. It should therefore be understood that second module (2120) may be sterilized between uses of instrument (2100), through various sterilization techniques as will be apparent to those of ordinary skill in the art in view of the teachings herein. After being sterilized and before being used, second module (2120) may be placed in a sterile bag (2130) as shown in
