Abstract

A powered surgical stapler is disclosed. The stapler includes a housing, an endoscopic portion extending distally from the housing and defining a first longitudinal axis, a drive motor disposed at least partially within a housing and a firing rod disposed in mechanical cooperation with the drive motor. The firing rod is rotatable by the motor about the first longitudinal axis extending therethrough. The stapler also includes an end effector disposed adjacent a distal portion of the endoscopic portion. The end effector is in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector. The stapler further includes a control system having a plurality of sensors coupled to the drive motor, the firing rod, the loading unit and the end effector, the plurality of sensors configured to detect operating parameters thereof. The control system also includes a microcontroller coupled to the plurality of sensors and being configured to determine operating status of the powered surgical stapler as a function of the detected operating parameters.

Description

[0001] References to related applications [0002] This application claims the benefit of and priority to US Provisional Application No. 60 / 997,854, filed October 5, 2007, entitled "Powered Surgical Suturing Device," which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to a surgical stapler for implanting mechanical surgical fasteners into tissue of a patient, and more particularly to a surgical stapler powered by an electric motor for launching surgical fasteners into tissue, and a A feedback controller for controlling the stapler in response to one or more sensory feedback signals. Background technique [0004] Currently known devices typically require 10-60 pounds of wrist force to grip and deploy tissue and form surgical fasteners, which can cause the surgeon's hand to become fatigued over repeated use. Gas-powered pneumatic staplers for implanting surgical fasteners into tissue are known in the art. Some of...
