Surgical forceps
A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.
1. A surgical forceps for treating tissue, comprising:
a pair of shafts each having a jaw member disposed at a distal end thereof, each shaft of the pair of shafts configured to rotate about a pivot to move the jaw members relative to each other;
a knife configured to cut tissue disposed between the jaw members;
a trigger extending from one of the shafts, the trigger operably coupled to the knife and rotatable to actuate the knife to cut tissue disposed between the jaw members; and
an anti-deployment link disposed adjacent to the trigger and configured to directly engage a rotatable trigger link extending from the trigger to prevent rotation of the trigger.
2. The surgical forceps according to claim 1 , further comprising a stop member disposed on at least one of the jaw members and configured to control a distance between the jaw members.
3. The surgical forceps according to claim 1 , further comprising an actuating mechanism operably coupled to the trigger, the trigger rotatable to cause the actuating mechanism to actuate the knife.
4. The surgical forceps according to claim 1 , wherein approximation of the pair of shafts moves the anti-deployment link out of engagement with the trigger link to permit rotation of the trigger.
5. The surgical forceps according to claim 1 , wherein the trigger includes a pair of handle members configured to be operated by a user's hand to rotate the trigger.
6. A surgical forceps for treating tissue, comprising:
a pair of shafts each having a jaw member disposed at a distal end thereof and a handle at a proximal end thereof, each handle defining a fingerhole configured to receive a finger of a user for rotating each shaft of the pair of shafts about a pivot to move the jaw members relative to each other;
a knife configured to cut tissue disposed between the jaw members;
a trigger extending from one of the shafts at a location distal to the handles, the trigger operably coupled to the knife and rotatable to actuate the knife to cut tissue disposed between the jaw members; and
an anti-deployment link disposed adjacent to the trigger and configured to directly engage a rotatable trigger link extending from the trigger at a location distal to the handles to prevent rotation of the trigger.
7. The surgical forceps according to claim 6 , further comprising a stop member disposed on at least one of the jaw members and configured to control a distance between the jaw members.
8. The surgical forceps according to claim 6 , further comprising an actuating mechanism operably coupled to the trigger, the trigger rotatable to cause the actuating mechanism to actuate the knife.
9. The surgical forceps according to claim 6 , wherein approximation of the pair of shafts moves the anti-deployment link out of engagement with the trigger link to permit rotation of the trigger.
10. The surgical forceps according to claim 6 , wherein the trigger includes a pair of handle members configured to be operated by a user's hand to rotate the trigger.
11. A surgical forceps for treating tissue, comprising:
a pair of shafts each having a jaw member disposed at a distal end thereof and a handle at a proximal end thereof, each handle defining a fingerhole configured to receive a finger of a user for rotating each shaft of the pair of shafts about a pivot to move the jaw members relative to each other;
a knife configured to cut tissue disposed between the jaw members;
a trigger extending from one of the shafts at a location distal to the handles, the trigger operably coupled to the knife and rotatable to actuate the knife to cut tissue disposed between the jaw members; and
an anti-deployment link disposed at a location distal to the handles and configured to directly engage a rotatable trigger link extending from the trigger at a location distal to the handles to prevent actuation of the knife.
12. The surgical forceps according to claim 11 , further comprising a stop member disposed on at least one of the jaw members and configured to control a distance between the jaw members.
13. The surgical forceps according to claim 11 , wherein approximation of the pair of shafts moves the anti-deployment link out of engagement with the trigger link to permit actuation of the knife.
14. The surgical forceps according to claim 11 , wherein the trigger includes a pair of handle members configured to be operated by a user's hand to rotate the trigger.
15. The surgical forceps according to claim 11 , further comprising an actuating mechanism operably coupled to the trigger, the trigger rotatable to cause the actuating mechanism to actuate the knife.
