Dissection scissors on surgical device

摘要

A surgical instrument includes a housing having first and second actuators and a shaft extends therefrom. End effector attaches to shaft and includes a first actuating device and a tissue treatment member. First actuating device is actuated by first actuator and includes first and second jaw members that actuate relative to one another about the first pivot. In a first position, jaw members are disposed in a spaced relation and in a second position cooperate to perform a first surgical procedure on tissue positioned therebetween. Second actuator deploys tissue treatment member relative to first jaw member from a first condition to a second condition. Tissue treatment member contacts the first jaw member in a first condition and a portion of the tissue treatment member is spaced away from the first jaw member and forms a loop between the tissue treatment member and first jaw member in a second condition.

主权项

1. A surgical instrument, comprising
a housing having a shaft that extends therefrom; an end effector attached to the distal end of the shaft, the end effector including:
a first actuating device having a first jaw member and a second jaw member, the first and second jaw members configured to move relative to one another about a first pivot from a first position wherein the first jaw member and second jaw member are disposed in spaced relation relative to one another to a second position wherein the first jaw member and second jaw member cooperate to perform a first surgical procedure on tissue positioned therebetween;a tissue treatment member configured to deploy relative to the first jaw member from a first condition, wherein a substantial portion of the length of the tissue treatment member contacts the first jaw member, to a second condition wherein at least a portion of the tissue treatment member is spaced away from the first jaw member and the tissue treatment member and the first jaw member form a loop therebetween; and a first actuator operably coupled to the housing and configured to actuate the jaw members from the first position to the second position and a second actuator operable coupled to the housing and configured to deploy the tissue treatment member from the first condition to the second condition, wherein a first end of the tissue treatment member is coupled to the first jaw member and a second end of the tissue treatment member is coupled to the second actuator.
