Electrosurgical instrument with restricted trigger

摘要

An apparatus for operating on tissue includes an end effector, a first actuator, and a second actuator. The end effector includes a first jaw pivotable relative to a second jaw to a closed position. The first actuator is movable from a first position to a second position to pivot the first jaw to the closed position. The first actuator engages the second actuator in the second position to selectively provide RF energy to the end effector.

1. An apparatus for operating on tissue, the apparatus comprising:
(a) an end effector, wherein the end effector comprises:
(i) a first jaw,(ii) a second jaw, wherein the first jaw is pivotable relative to the second jaw, wherein the first jaw is configured to pivot from an open position to a closed position, wherein one or both of the first jaw or the second jaw is operable to deliver energy to tissue, and(iii) a cutting member operable to sever tissue captured between the first and second jaws; (b) a first actuator, wherein the first actuator is movable from a first position to a second position, wherein the first actuator is operable to pivot the first jaw from the open position to the closed position when the first actuator is moved from the first position to the second position, wherein the first actuator is further operable to drive the cutting member when the first actuator is moved from the second position to a third position; and (c) a second actuator, wherein the first actuator is configured to engage the second actuator when the first actuator is in the second position, wherein the second actuator is operable to selectively energize the one or both of the first jaw or the second jaw to deliver energy to tissue when the first actuator is engaged with the second actuator.
