Two-Stage Switch for Surgical Device

摘要

A surgical device assembly includes a vessel-sealing end effector having opposing surfaces engaging tissue when disposed therebetween, at least one of the surfaces having an energy delivering component, and a surgical device handle. The surgical device handle is connected to the end effector and has a switch with a switch-actuation direction in which the switch actuates, an unactuated position at a rest point of the switch, a first actuated position at first distance from the rest point in the switch-actuation direction, a second actuated position at a second distance further from the rest point in the switch-actuation direction than the first distance, and a force required to sustain the first actuated position being less than a force required to enter the second actuated position. The energy delivering component delivers energy when in at least one of the first and second actuated positions.

1. A surgical device assembly, comprising:
a vessel-sealing end effector having opposing surfaces engaging tissue when disposed therebetween, at least one of the surfaces having an energy delivering component; and a surgical device handle connected to the end effector and having a switch with:
a switch-actuation direction in which the switch actuates;an unactuated position at a rest point of the switch;a first actuated position at first distance from the rest point in the switch-actuation direction;a second actuated position at a second distance further from the rest point in the switch-actuation direction than the first distance; anda force required to sustain the first actuated position being less than a force required to enter the second actuated position; and the energy delivering component delivering energy when in at least one of the first and second actuated positions.
