Abstract

A method for operating a surgical instrument includes mechanically coupling a manual release to a transmission of a surgical instrument having a self-contained power supply disposed entirely within a handle thereof. The transmission translates movement of an electrically powered motor inside the handle to movement of a part of a surgical end effector connected to the handle. The part is operable to move anywhere between a start position and a fully actuated position. The method further includes selectively interrupting the transmission with the manual release to move the part towards the start position independent of motor operation.

Description

[0001] This application is a divisional application of the patent application with the application number 200780017794.0, the application date being May 31, 2007, and the invention title being "Electric Surgical Instrument". technical field [0002] The invention belongs to the field of surgical instruments, especially, but not limited to, an anastomosis device.
