Articulating surgical apparatus

摘要

An endoscopic instrument includes a housing having shaft extending therefrom that defines a longitudinal axis therethrough. The shaft includes an articulating section disposed thereon. The articulating section has a central annulus extending therealong and first and second pluralities of bores. The first plurality of bores configured to receive corresponding tendons therethrough and the second plurality of bores configured to receive corresponding conductive leads therethrough. An end effector assembly operatively connected to a distal end of the shaft including a pair of first and second jaw members. The corresponding conductive leads transition from a first state for enabling articulation of the shaft about the articulating section, to a second state for disabling articulation of the shaft about the articulating section.

1. A surgical system, comprising:
an endoscopic instrument, including:
a shaft defining a longitudinal axis and including an articulating section having a plurality of links aligned along a length of the articulating section, the articulating section defining at least one first bore extending through each of the plurality of links and at least one second bore extending through each of the plurality of links,a tendon extending through the first bore;a conductive lead extending through the second bore; andan end effector assembly operatively connected to a distal end of the shaft,wherein, in response to application to energy to the conductive lead, the conductive lead is configured to transition from a first state, enabling articulation of the shaft about the articulating section, to a second state, disabling articulation of the shaft about the articulating section.
