Abstract
A handle assembly for operating a surgical instrument is provided and includes a housing; a trigger operatively supported on the housing; and at least one actuation cable operatively associated with the trigger and extending from the housing in such a manner that an actuation of the trigger imparts both an axial translation of the actuation cable and a rotation to the actuation cable. Each of the axial translation and rotation of the actuation cable performs a separate function.
Claims37
A handle assembly for operating a surgical instrument, comprising:
- a housing;
- a trigger operatively supported on the housing;
- and
- at least one actuation cable operatively associated with the trigger and extending from the housing in such a manner that an actuation of the trigger, in a single directional motion, imparts both an axial translation of the actuation cable and a rotation to the actuation cable, wherein each of the axial translation and rotation of the actuation cable performs a separate function.
An endoscopic stitching device, comprising:
- a handle assembly, including:
- a housing;
- a trigger operatively supported on the housing;
- and
- at least one actuation cable operatively associated with the trigger and extending from the housing in such a manner that a motion of actuation of the trigger, in a single direction, imparts both an axial translation of the actuation cable and a rotation to the actuation cable, wherein each of the axial translation and rotation of the actuation cable performs a separate function;
- and
- an end effector operatively connected to the handle assembly, the end effector including a tool assembly configured and adapted to perform at least a pair of operations,
- wherein the actuation cable is operatively connected to the tool assembly in such a manner that the actuation cable is capable of effecting a first operation of the pair of operations of the end effector upon the axial translation thereof;
- and
- wherein the actuation cable is operatively connected to the tool assembly in such a manner that the actuation cable is capable of effecting a second operation of the pair of operations of the end effector upon the rotation thereof.
