Surgical stapling device with independent tip rotation

摘要

A surgical stapling device is disclosed which includes a handle assembly, an endoscopic body portion and a tool assembly. The tool assembly is rotatably and pivotally supported on a distal end of the endoscopic body portion. A tool assembly rotation mechanism is provided which includes a rotation knob, a substantially rigid tube and a flexible member interconnecting the rigid tube to the tool assembly. The substantially rigid tube translates rotation of the rotation knob to rotation of the flexible member and provides a channel for passage of other components of the surgical stapling device.

主权项

1. A surgical device comprising:
an elongate body portion defining a first longitudinal axis; a tool assembly defining a second longitudinal axis and being rotatably supported at a distal end of the body portion, about the second longitudinal axis; an actuation member associated with the tool assembly; a tool assembly rotation mechanism including a substantially rigid tube positioned within the body portion and having a proximal end and a distal end, the distal end being operably connected to the tool assembly via a flexible member; a flexible firing cable operably connected to the actuation member, the flexible firing cable extending through the substantially rigid tube of the tool assembly rotation mechanism; the flexible member being hollow and the flexible firing cable extending through the hollow flexible member; a handle assembly including a stationary handle portion and an operating trigger, wherein the operating trigger is operably connected to the actuation member by a flexible retraction cable, the flexible firing cable being operable in tension to move the actuation member in one direction along the second longitudinal axis of the tool assembly and the flexible retraction cable being operable in tension to move the actuation member in an opposite direction along the second longitudinal axis.
