Flexible endoscopic stitching devices

摘要

An endoscopic stitching device is provided including an end effector configured and adapted to perform at least a pair of functions; and a single actuation cable operatively connected to the end effector, wherein the actuation cable is capable of effecting operation of at least the pair of functions. The actuation cable is capable of effecting a first operation of the pair of functions upon an axial translation thereof, and a second operation of the pair of functions upon a rotation thereof.

1. An endoscopic stitching device, comprising:
a tool assembly including a pair of juxtaposed jaws associated with one another, each jaw defining a needle receiving recess formed in a tissue contacting surface thereof; a pair of needle engaging blades slidably supported, one each, in a respective jaw, each blade including an advanced position wherein a portion of the blade engages a suture needle when the suture needle is in the respective jaw, to thereby secure the suture needle therewith, and a retracted position wherein the blade is out of engagement with the suture needle, to thereby permit the suture needle to be removed from the jaw; and an actuation cable operatively coupled to the tool assembly and the pair of needle engaging blades, wherein an axial translation of the actuation cable effects a first function of the tool assembly, wherein the pair of blades are operatively joined to one another so as to translate in opposite directions relative to one another upon a rotation of the actuation cable.
