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 device for treating tissue, comprising:
a pair of shafts configured to rotate relative to each other about a pivot;
a trigger extending from one of the shafts and configured to rotate to actuate a knife;
a rotatable trigger link extending from the trigger; and
an anti-deployment link disposed adjacent to the trigger and configured to directly engage the rotatable trigger link to prevent rotation of the trigger.
2. The surgical device 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.
3. The surgical device according to claim 1 , wherein approximation of the pair of shafts moves the anti-deployment link out of engagement with the rotatable trigger link to permit rotation of the trigger.
4. The surgical device 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.
5. The surgical device according to claim 1 , wherein each shaft of the pair of shafts includes a jaw member disposed at a distal end thereof, and rotation of the pair of shafts about the pivot moves the jaw members relative to each other.
6. The surgical device according to claim 5 , further comprising a stop member disposed on at least one of the jaw members and configured to control a distance between the jaw members.
7. A surgical device for treating tissue, comprising: a pair of shafts configured to rotate relative to each other about a pivot; a rotatable trigger link coupled to one of the shafts; a knife operably coupled to the rotatable trigger link and configured to cut tissue; a rotatable trigger coupled to one of the shafts and extending from the rotatable trigger link, the rotatable trigger configured to actuate the knife; and an anti-deployment link disposed adjacent to the rotatable trigger and configured to directly engage the rotatable trigger linkto prevent actuation of the knife.
8. The surgical device according to claim 7 , wherein the trigger includes a pair of handle members configured to be operated by a user's hand to rotate the trigger.
9. The surgical device according to claim 7 , wherein approximation of the pair of shafts moves the anti-deployment link out of engagement with the rotatable trigger link to permit actuation of the knife.
10. The surgical device according to claim 7 , wherein each shaft of the pair of shafts includes a jaw member disposed at a distal end thereof, and rotation of the pair of shafts about the pivot moves the jaw members relative to each other.
11. The surgical device according to claim 10 , further comprising a stop member disposed on at least one of the jaw members and configured to control a distance between the jaw members.
12. A surgical device 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 and operably coupled to the knife, the trigger rotatable to actuate the knife to cut tissue disposed between the jaw members; and
a rotatable trigger link extending from the trigger and configured to be directly engaged by an anti-deployment link to prevent rotation of the trigger.
13. The surgical device according to claim 12 , wherein approximation of the pair of shafts moves the anti-deployment link out of engagement with the rotatable trigger link to permit actuation of the knife.
14. The surgical device according to claim 12 , 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 device according to claim 12 , further comprising an actuating mechanism operably coupled to the trigger, the trigger rotatable to cause the actuating mechanism to actuate the knife.
16. The surgical device according to claim 12 , further comprising a stop member disposed on at least one of the jaw members and configured to control a distance between the jaw members.
