Technical Field
The present disclosure relates to a surgical forceps, and more particularly, to an electrosurgical forceps capable of sealing and cutting tissue.
Background of Related Art
A forceps is a plier-like instrument that relies on mechanical action between its jaws to grasp, clamp and constrict vessels or tissue. Electrosurgical forceps utilize both mechanical clamping action and electrical energy to affect hemostasis by heating tissue and blood vessels to coagulate and/or cauterize tissue. Certain surgical procedures require more than simply cauterizing tissue and rely on the unique combination of clamping pressure, precise electrosurgical energy control and gap distance (i.e., distance between opposing jaw members when closed about tissue) to “seal” tissue, vessels and certain vascular bundles.
Typically, once a vessel is sealed, the surgeon has to accurately sever the vessel along the newly formed tissue seal. Accordingly, many vessel sealing instruments have been designed that incorporate a knife or blade member that effectively severs the tissue after forming a tissue seal. Many of such instruments require the surgeon to actuate a first trigger to grasp tissue between the jaw members, e.g., to perform the sealing operation, and then to actuate a second trigger once the tissue seal has been formed, to advance the knife through tissue to sever the newly formed tissue seal.
It would therefore be advantageous to develop an instrument that reduces the number of steps required to grasp, seal, and cut tissue. For example, commonly-assigned U.S. Pat. No. 7,628,791 to Garrison et al., the entire contents of which are hereby incorporated by reference herein, discloses a single-action tissue sealer capable of grasping, sealing and cutting tissue in a single action.
In accordance with the present disclosure, a forceps is provided. The forceps includes an end effector assembly having first and second jaw members disposed in opposed relation relative to one another. One (or both) of the jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween. A knife is longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position. The knife is coupled to one (or both) of the jaw members via a pin-slot engagement such that, upon translation of the knife from the retracted position to the intermediate position, the first and second jaw members are moved to the approximated position to grasp tissue therebetween and such that, upon translation of the knife from the intermediate position to the extended position, the knife is extended between the jaw members to cut tissue grasped therebetween.
In one embodiment, each of the first and second jaw members includes an opposed electrically conductive tissue sealing surface adapted to connect to an electrosurgical energy source to communicate energy to tissue grasped between the jaw members.
In another embodiment, one (or both) of the first and second jaw members includes a knife channel defined therein. The knife channel(s) is configured to permit reciprocation of the knife therethrough. The knife channel(s) may define a T-shaped longitudinal cross-sectional configuration or an L-shaped longitudinal cross-sectional configuration. Further, the knife may define a longitudinal cross-sectional configuration complementary to longitudinal cross-sectional configuration of the knife channel(s).
In yet another embodiment, the knife includes a slot defined therein and wherein one of the jaw members, e.g., the first jaw member, includes a pin engaged within the slot. The slot defined within the knife is configured such that, when the knife is translated from the retracted position to the intermediate position, the first and second jaw members are moved from the spaced-apart position to the approximated position to grasp tissue therebetween. The slot may further be configured such that, upon translation of the knife from the intermediate position to the extended position, the knife is extended between the jaw members to cut tissue grasped therebetween.
Alternatively, the knife may include a pin engaged thereon in transverse relation relative thereto and the first and second jaw members may each include a slot defined therethrough. In such an embodiment, the slots are configured such that, when the knife is translated from the retracted position to the intermediate position, the first and second jaw members are moved from the spaced-apart position to the approximated position to grasp tissue therebetween. The slots may further be configured such that, upon translation of the knife from the intermediate position to the extended position, the knife is extended at least partially between the jaw members to cut tissue grasped therebetween.
In still another embodiment, when the first and second jaw members are disposed in the approximated position, a pre-determined gap distance is defined therebetween.
In still yet another embodiment, a handle assembly is provided. The handle assembly is coupled to the end effector assembly and is selectively moveable between an initial position, a first actuated position, and a second actuated position for translating the knife between the retracted position, the intermediate position, and the extended position, respectively. The handle assembly may further include one or more feedback features for providing audible, tactile, and/or visual feedback as to the position of the handle assembly.
Another embodiment of a forceps provided in accordance with the present disclosure includes a handle assembly including a moveable handle moveable between a first position, a second position, and a third position. The handle assembly has a shaft extending distally therefrom. An end effector assembly is disposed at a distal end of the shaft and includes first and second jaw members disposed in opposed relation relative to one another. One or both of the jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween. One or both of the jaw members further includes a pin extending therethrough. A knife bar is disposed within the shaft and is longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position upon movement of the moveable handle between the first position, the second position, and the third position, respectively. The knife bar includes a slot defined therein that is configured to receive the pin of the jaw member(s) therethrough such that, upon translation of the knife bar from the retracted position to the intermediate position, the first and second jaw members are moved to the approximated position to grasp tissue therebetween and such that, upon translation of the knife bar from the intermediate position to the extended position, the knife bar is extended between the jaw members to cut tissue grasped therebetween.
Yet another embodiment of a forceps provided in accordance with the present disclosure similarly includes a handle assembly having a moveable handle that is moveable between a first position, a second position, and a third position. A shaft extends distally from the handle assembly and includes an end effector assembly disposed at a distal end thereof. The end effector assembly includes first and second jaw members disposed in opposed relation relative to one another. One or both of the jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween. One or both of the jaw members includes a proximal flange having a slot defined therethrough. A knife bar is disposed within the shaft and is longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position upon movement of the moveable handle between the first position, the second position, and the third position. The knife bar includes a pin engaged therein and extending transversely relative thereto that is configured for engagement within the slot(s) of the jaw member(s) such that, upon translation of the knife bar from the retracted position to the intermediate position, the first and second jaw members are moved to the approximated position to grasp tissue therebetween and such that, upon translation of the knife bar from the intermediate position to the extended position, the knife bar is extended between the jaw members to cut tissue grasped therebetween.

As mentioned above, knife bar 142 is coupled to jaw member 110. More particularly, proximal flanges 113 of jaw member 110 each include a second aperture 116 defined therethrough and offset below first apertures 114, while knife bar 142 includes a longitudinal slot 147 defined therein. During assembly, knife bar 142 is positioned between proximal flanges 113 of jaw member 110 and a pin 105 is inserted through second aperture 116 of one proximal flange 113 of jaw member 110, through slot 147 of knife bar 142, and through second aperture 116 of the other proximal flange 113 of jaw member 110. Pin 105 is secured within second apertures 116 of proximal flanges 113 on either side of knife bar 142 to securely couple knife bar 142 and jaw member 110 to one another. Alternatively, as will be described below with reference to
As a result of the above-described coupling of knife bar 142 and jaw member 110, pin 105 is translated along slot 147 of knife bar 142 when knife bar 142 is translated longitudinally with respect to jaw member 110 due to the engagement of pin 105 within second apertures 116 of proximal flanges 113 of jaw member 110. Further, as pin 105 is translated along slot 147, the transverse position of pin 105 relative to longitudinal axis “A-A” is determined by the configuration of slot 147 of knife bar 142. For example, if pin 105 were translated along an upwardly sloping portion of slot 147, slot 147 would urge pin 105 upwardly, e.g., in a positive direction relative to longitudinal axis “A-A.” The upward urging of pin 105 would thereby urge jaw member 110 to rotate in a first direction about pivot pin 103 due to the offset position of pin 105 relative to pivot pin 103. On the other hand, if pin 105 were translated along a downwardly sloping portion of slot 147, pin 105 would be urged downwardly, e.g., in a negative direction relative to longitudinal axis “A-A,” thereby urging jaw member 110 to rotate in a second, opposite direction about pivot pin 103. Put more generally, the configuration of slot 147 of knife bar 142 controls the displacement of pin 105 relative to longitudinal axis “A-A” as knife bar 142 is translated relative to jaw member 110. The displacement of pin 105, e.g., the upward or downward movement of pin 105, as knife bar 142 is translated relative to jaw member 110, in turn, urges jaw member 110 to rotate about pivot pin 103 in a first or second direction, e.g., in a clockwise or counterclockwise direction, depending on the direction of displacement.
Accordingly, slot 147 of knife bar 142 may be specifically configured to pivot jaw member 110 about pivot pin 103 and relative to jaw member 120 from the spaced-apart position to the approximated position, from the approximated position to the spaced-apart position, or to maintain the relative position of jaw members 110, 120, as knife bar 142 is translated relative to jaw members 110, 120. Further, slot 147 may define segments of varying configuration such that jaw members 110, 120 may be approximated (in a grasped position), maintained in position, and/or opened upon translation of knife bar 142 relative to jaw members 110, 120 in a single direction. As such, although only one particular configuration of slot 147 will be described below, slot 147 may be configured to achieve any desired combination of approximating, opening and maintaining the position of jaw members 110, 120 upon translation of knife bar 142 with respect to jaw members 110, 120.

Next, as shown in
With continued reference to
In the intermediate position, as shown in
In use, with tissue grasped between jaw members 110, 120 and, more particularly, between sealing surfaces 112, 122 of jaw members 110, 120, respectively, electrosurgical energy may be supplied to sealing surfaces 112, 122 and conducted through tissue grasped therebetween to effect a tissue seal.
Turning now to
Once tissue has been grasped, sealed and/or divided, as mentioned above, knife bar 142 may be translated proximally from the extended position, through the intermediate position, and back to the proximal-most position to move jaw members 110, 120 back to the spaced-apart position to release the sealed and divided tissue. Thereafter, end effector assembly 100 may be removed from the surgical site.
Referring now to
With continued reference to
In the initial position “P0,” jaw members 110, 120 are disposed in the spaced-apart position, as shown in
More specifically, as shown in
As shown in
Once tissue has been adequately sealed, or where it is desired to only cut tissue, moveable handle 40 may be moved further against the bias of spring 38 from the first actuated position “P1” to the second actuated position “P2.” As mentioned above, moving moveable handle 40 to the second actuated position “P2” advances knife blade 144 between jaw members 110, 120, e.g., through blade channels 115a, 115b (
Handle assembly 30 may be configured as a two-step mechanism, e.g., moveable handle 40 may be configured to first move from the initial position “P0” to the first actuated position “P1” and then, upon the application of additional force, move from the first actuated position “P1” to the second actuated position “P2”, or, alternatively, may be configured as a continuous, single stroke mechanism, e.g., moveable handle 40 is moved from the initial position “F0” through the first actuated position “P1” for grasping and or sealing tissue and to the second actuated position “P2” for cutting tissue. Other configurations of handle assembly 30 are also contemplated, so long as handle assembly 30 is configured to move jaw member 110, 120 between the spaced-apart position and the approximated position, and to advance knife blade 144 therebetween.
As can be appreciated from the above, handle assembly 30 and knife assembly 140 cooperate with end effector assembly 100 to move jaw members 110, 120 between the spaced-apart and approximated positions and to advance knife blade 144 therebetween with minimal components. However, while the same mechanism is used to move jaw members 110, 120 between the spaced-apart and approximated positions to grasp (and seal) tissue and to advance knife blade 144 between jaw members 110, 120 to cut tissue, the grasping/sealing and cutting functions remain independent of one another. In other words, end effector assembly 100 may be used for grasping and sealing tissue, for grasping and cutting tissue, or for grasping, sealing, and cutting tissue.

A knife assembly 240, similar to knife assembly 140 (
