Technical Field
The present disclosure relates generally to surgical instruments and, more particularly, to surgical instruments capable of being disassembled to facilitate replacement of any disposable component(s) and/or sterilization of any reusable component(s) of the surgical instrument for reuse.
Background of Related Art
Generally, surgical instruments are classified as disposable, e.g., instruments that are discarded after a single use; partially-reusable or reposable, e.g., instruments including both disposable components that are discarded after a single use and reusable components that are sterilizable for repeated use; or reusable, e.g., instruments that are fully sterilizable for repeated use. As can be appreciated, reusable and partially-reusable surgical instruments help reduce the costs associated with the particular surgical procedures for which they are used. However, although reusable and partially-reusable surgical instruments are cost-effective, the requirements of these reusable and partially-reusable surgical instruments present significant design challenges. More specifically, reusable and partially-reusable surgical instruments must be capable of performing the same functions as their disposable counterparts, resist significant degradation during their useful lives, allow for adequate sterilization of any reusable components, and allow for efficient replacement of any disposable components.
As used herein, the term “distal” refers to the portion that is being described that is further from a user, while the term “proximal” refers to the portion that is being described that is closer to a user. Further, to the extent consistent, any of the aspects described herein may be used in conjunction with any of the other aspects described herein.

Cam slots 117, 127 are configured to receive a drive pin 161 that is coupled to drive member 160 such that translation of drive member 160 relative to jaw members 110, 120 urges drive pin 161 through cam slots 117, 127 to pivot jaw members 110, 120 relative to one another between the spaced-apart position and the approximated position for grasping tissue between surfaces 112, 122 of jaw members 110, 120.
Electrical leads 180, 190 are coupled to respective electrically-conductive surfaces 112, 122 at one end thereof and are configured to ultimately couple with corresponding wires 88a, 88b (
Shaft portion 130 of end effector assembly 100 includes inner and outer semi-tubular members 132, 142. Inner semi-tubular member 132 includes a plurality of protrusions 134 extending outwardly therefrom, while outer semi-tubular member 142 defines a plurality of apertures 144 configured to receive protrusions 134 in snap-fit engagement to secure inner and outer semi-tubular members 132, 142 to one another, although other suitable engagements are also contemplated. Inner semi-tubular member 132 further includes a release button 136 extending proximally therefrom. Release button 136 is integrally formed with or otherwise engaged to inner semi-tubular member 132 in a cantilevered arrangement and is at least partially flexible so as to allow the free end of release button 136 to move relative to inner semi-tubular member 132, e.g., upon depression of release button 136. An engagement tab 138 extends from the free end of release button 136. Engagement tab 138 includes a body portion 139a configured to facilitate mechanical engagement of end effector assembly 100 with shaft 12, and an electrically-conductive contact 139b disposed on an underside of body portion 139a. Electrical lead 180 is coupled to electrically-conductive contact 139b to facilitate electrical coupling of electrically-conductive plate 112 of jaw member 110 with the corresponding wire 88a of forceps 10, as detailed below. Outer semi-tubular member 142 defines a window 146 towards the proximal end thereof within which body portion 139a of engagement tab 138 is at least partially received. Window 146 provides access to release button 136 to permit manual depression of release button 136, as detailed below.
Jaw support assembly 150 includes first and second jaw supports 152, 154 disposed on either side of proximal flanges 114, 124 of jaw members 110, 120, respectively. More specifically, jaw support 152 is positioned adjacent proximal flange 114 of jaw member 110, while jaw support 154 is positioned adjacent proximal flange 124 of jaw member 120. Each jaw support 152, 154 defines an aperture 153, 155 therethrough. Apertures 153, 155 are configured to receive the ends of pivot pin 101, which extends between jaw supports 152, 154 and through apertures 116, 126 of jaw members 110, 120.

Jaw support 154 includes an electrically-conductive male connector 156 retained therein. Electrical lead 190 is coupled to electrically-conductive male connector 156 to facilitate electrical coupling of electrically-conductive plate 122 of jaw member 120 with the corresponding wire 88b (
End effector assembly 100 is designed as a bilateral assembly, i.e., where both jaw member 110 and jaw member 120 are movable relative to one another and to jaw support assembly 150. However, end effector assembly 100 may alternatively be configured as a unilateral assembly, i.e., wherein one of the jaw members 110, 120 is fixed with respect to jaw supports 152, 154, and wherein the other jaw member 110, 120 is movable relative to jaw supports 152, 154 and the fixed jaw 110, 120.
Drive member 160 of end effector assembly 100 includes first and second drive plate segments 162, 164 disposed on either side of knife 170. Drive pin 161 extends through respective apertures 163, 165 defined within drive plate segments 162, 164 of drive member 160 and through a longitudinal slot 172 defined within knife 170 to secure drive plate segments 162, 164 to one another on either side of knife 170. Knife 170 and drive member 160 are slidable relative to one another via translation of drive pin 161 through longitudinal slot 172 of knife 170. As noted above, the ends of drive pin 161 are received within cam slots 117, 127 of jaw members 110, 120 such that translation of drive member 160 relative to jaw members 110, 120 urges drive pin 161 through cam slots 117, 127 to pivot jaw members 110, 120 relative to one another between the spaced-apart position and the approximated position for grasping tissue between surfaces 112, 122. Drive plate segments 162, 164 each further include a neck 166,168 extending from a proximal end thereof to a respective head 167, 169. Necks 166, 168 define reduced diameters as compared to respective heads 167, 169, the importance of which is detailed below.
Knife 170 defines a distal cutting edge 174, a proximal aperture 176 to enable releasable engagement of knife 170 with knife bar 64, and, as mentioned above, defines a longitudinal slot 172 configured to receive pivot pin 101 and drive pin 161 therethrough. In use, as detailed below, knife 170 is selectively translatable between and relative to jaw members 110, 120 to cut tissue grasped therebetween.

With reference to
Shaft 12 of forceps 10 defines a cut-out 13 such that a distal portion 14 of shaft 12 defines a semi-tubular configuration. The semi-tubular configuration of distal portion 14 of shaft 12 cooperates with shaft portion 130 of end effector assembly 100, when end effector assembly 100 is engaged to shaft 12, such that body portion 15 of shaft 12 and the cooperating distal portion 14 of shaft 12 and shaft portion 130 of end effector assembly 100 fully form a tubular shaft member extending between housing 20 and jaw members 110, 120.
Body portion 15 of shaft 12 defines a window 16 adjacent distal portion 14 of shaft 12. A cap 17 defining a body 18a is configured to engage body portion 15 of shaft 12 via a pin-aperture engagement 18b. Cap 17 includes an electrically-conductive spring contact 18c (
Drive bar 42 defines a generally tubular body portion 44 and a semi-tubular distal portion 46 that extends distally from body portion 44. A neck 47 extends from a distal end of distal portion 46 of drive bar 42 to a head 48. Neck 47 defines reduced diameter as compared to head 48 such that, as detailed below, upon engagement of end effector assembly 100 with shaft 12, neck 47 is configured to receive heads 167, 169 of drive plate segments 162, 164 of drive member 160 and necks 166, 168 of drive plate segments 162, 164 of drive member 160 are configured to receive head 48 of drive bar 42 to operably engage drive bar 42 and drive member 160 with one another.
Knife bar 64 defines a generally tubular body portion 66 and a semi-tubular distal portion 67 that extends distally from body portion 66. An engagement finger 68 extends distally from semi-tubular distal portion 67 of knife bar 64. As detailed below, upon engagement of end effector assembly 100 with shaft 12, engagement finger 68 is received within aperture 176 of knife 170 to operably engage knife bar 64 and knife 170 with one another.
Referring again to
Thereafter, end effector assembly 100 is slid proximally relative to shaft 12 sufficiently such that engagement tab 138 of end effector assembly 100 is at least partially received, e.g., in snap-fit engagement, within window 16 of shaft 12 between spring contact 18c and body 18a of cap 17, such that engagement finger 68 of knife bar 64 is received within aperture 176 of knife 170, such that neck 47 of drive bar 42 receives heads 167, 169 of drive plate segments 162, 164 and necks 166, 168 of drive plate segments 162, 164 receive head 48 of drive bar 42, and such that female connector 19 at least partially receives male connector 156 of jaw support 154. Upon receipt of engagement tab 138 within window 16 between spring contact 18c and body 18a of cap 17, spring contact 18c is biased into mating engagement with contact 139b of engagement tab 138. Thus, sufficient proximal sliding of end effector assembly 100 relative to shaft 12 mechanically engages shaft portion 130 with shaft 12, mechanically engages drive bar 42 with drive plate segments 162, 164, mechanically engages knife bar 64 with knife 170, electrically couples electrical leads 180, 190 with corresponding wires 88a, 88b.
Once end effector assembly 100 is engaged with shaft 12 as detailed above, forceps 10 is ready for use. With respect to the use of forceps 10, e.g., for grasping, treating, and/or cutting tissue, with jaw members 110, 120 disposed in the spaced-apart position, end effector assembly 100 may be maneuvered into position, e.g., via manipulating housing 20 and/or rotation wheel 72 of rotation assembly 70, such that tissue to be grasped, treated, and/or cut, is disposed between jaw members 110, 120. Next, movable handle 40 is compressed relative to fixed handle 50 to translate drive bar 42 and, thus, drive plate segments 162, 164 relative to jaw members 110, 120 to pivot jaw members 110, 120 relative to one another from the spaced-apart position to the approximated position to grasp tissue therebetween. Thereafter, activation switch 84 may be activated to initiate the supply of energy from the generator (not shown) to electrically-conductive surfaces 112, 122 of jaw members 110, 120, e.g., via wires 88a, 88b, electrical leads 180, 190, and the respective contacts and connectors 18c, 139b and 19, 156 therebetween. More specifically, energy may be supplied to surface 112 of jaw member 110 and/or surface 122 of jaw member 120 and conducted through tissue to treat tissue, e.g., to effect a tissue seal or otherwise treat tissue. Once tissue treatment is complete (or to cut untreated tissue), trigger 62 is actuated to translate knife bar 64 and, thus, knife 170 relative to jaw members 110,120 from the retracted position to the extended position to cut tissue grasped between jaw members 110, 120. When tissue cutting is complete, trigger 62 may be released or returned to return knife 170 to the retracted position. Thereafter, movable handle 40 may be released or returned to return jaw members 110, 120 to the spaced-apart position to release the treated and/or divided tissue. The above may subsequently be repeated in whole or in part, depending upon the particular procedure to be performed.
In order to disengage end effector assembly 100 from shaft 12, e.g., upon completion of the procedure or to engage another (similar or different) end effector assembly with forceps 10, release button 136 is depressed and, while depressing release button 136 (at least initially), end effector assembly 100 is slid distally relative to shaft 12. Depression of release button 136 withdraws engagement tab 138 from window 16 to disengage shaft portion 130 from shaft 12 and, at or near the same time, urges engagement finger 68 from aperture 176 to disengage knife bar 64 from knife 170. Distal sliding of end effector assembly 100 relative to shaft 12 permits decoupling of respective heads 167, 169 and 48 from necks 47 and 166, 168, withdrawal of male connector 156 from female connector 19, and decoupling of contact 139b from contact 18c. As such, by depressing release button 136 and sliding end effector assembly 100 distally relative to shaft 12, end effector assembly 100 may be disengaged from shaft 12.
Once end effector assembly 100 has been fully disengaged from shaft 12, the various components of end effector assembly 100 may pivoted relative to one another to the fanned-apart position (
Turning now to
Channels 214, 234 defined within first and second components 210, 230 are configured to align with one another to fully form lumen 250 upon engagement of first and second components 210, 230 with one another. One of the channels, e.g., channel 234 of second component 230 is configured to retain semi-tubular shaft portion 130 of end effector assembly 100 therein, while the other channel, e.g., channel 214 of first component 210, is configured to slidably receive semi-tubular distal portion 14 of shaft 12 therein.
Second component 230 further includes a pair of spaced-apart, flexible bands 236 extending along at least a portion of channel 234 on either side thereof. Each band 236 includes a finger 238 extending therefrom in generally perpendicular orientation relative to the respective band 236. Fingers 238 are configured to urge flexible bands 236 apart from one another upon insertion of shaft portion 130 of end effector assembly 100 therebetween. Once shaft portion 130 is seated within channel 234, bands 236 are permitted to return to their initial positions to retain end effector assembly 100 in position within second component 230. First component 210 defines a cavity 216 that opposes fingers 238 and is configured to receive fingers 238 upon engagement of first and second components 210, 230 with one another.
Second component 230 also includes a rotating block 240 pivotably coupled thereto and at least partially disposed within channel 234 thereof. More specifically, rotating block 240 is rotatable between a blocking position (
In use, in order to engage end effector assembly 100 with shaft 12 using assembly tool 200, first and second components 210, 230 are initially disengaged from one another, as shown in
Referring to
Once end effector assembly 100 has been engaged with shaft 12 as detailed above, first and second components 210, 230 of assembly tool 200 may be disengaged from one another and removed from end effector assembly 100 and shaft 12, as shown in
The various embodiments disclosed herein may also be configured to work with robotic surgical systems and what is commonly referred to as “Telesurgery.” Such systems employ various robotic elements to assist the surgeon in the operating room and allow remote operation (or partial remote operation) of surgical instrumentation. Various robotic arms, gears, cams, pulleys, electric and mechanical motors, etc. may be employed for this purpose and may be designed with a robotic surgical system to assist the surgeon during the course of an operation or treatment. Such robotic systems may include remotely steerable systems, automatically flexible surgical systems, remotely flexible surgical systems, remotely articulating surgical systems, wireless surgical systems, modular or selectively configurable remotely operated surgical systems, etc.
The robotic surgical systems may be employed with one or more consoles that are next to the operating theater or located in a remote location. In this instance, one team of surgeons or nurses may prep the patient for surgery and configure the robotic surgical system with one or more of the instruments disclosed herein while another surgeon (or group of surgeons) remotely control the instruments via the robotic surgical system. As can be appreciated, a highly skilled surgeon may perform multiple operations in multiple locations without leaving his/her remote console which can be both economically advantageous and a benefit to the patient or a series of patients.
The robotic arms of the surgical system are typically coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the working ends of any type of surgical instrument (e.g., end effectors, graspers, knifes, scissors, etc.) which may complement the use of one or more of the embodiments described herein. The movement of the master handles may be scaled so that the working ends have a corresponding movement that is different, smaller or larger, than the movement performed by the operating hands of the surgeon. The scale factor or gearing ratio may be adjustable so that the operator can control the resolution of the working ends of the surgical instrument(s).
The master handles may include various sensors to provide feedback to the surgeon relating to various tissue parameters or conditions, e.g., tissue resistance due to manipulation, cutting or otherwise treating, pressure by the instrument onto the tissue, tissue temperature, tissue impedance, etc. As can be appreciated, such sensors provide the surgeon with enhanced tactile feedback simulating actual operating conditions. The master handles may also include a variety of different actuators for delicate tissue manipulation or treatment further enhancing the surgeon's ability to mimic actual operating conditions.
From the foregoing and with reference to the various drawing figures, those skilled in the art will appreciate that certain modifications can also be made to the present disclosure without departing from the scope of the same. While several embodiments of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
