Embodiment Construction

[0124] In one embodiment, a pneumatic instrument includes an integrated pneumatic system and electrical control, recording and / or feedback elements. In one embodiment, the pneumatic system is combined with an electrical control system to pneumatically actuate the instrument and electrically control the flow rate in the pneumatic system. The actuator can be used for pressurization of the electro-pneumatic system. A control system receives pressurized gas from a source and generates an electrical output to actuate an element of an instrument using at least one electrical component or element. A control system may be used to control elements of the surgical cutting and fastening instrument. The cutting and fastening elements are operated pneumatically by the controller. Thus, the actuation of the pneumatic cylinders can be controlled with pressurized gas and a controller. The controller controls the rate at which pressurized gas is released in the pneumatic system. A controll...

Abstract

The present invention discloses a pneumatically powered surgical cutting and fastening instrument with electrical control and recording mechanisms. A surgical instrument includes an end effector. A moveable cutting instrument for cutting an object positioned in the end effector is disposed within the end effector. A pneumatically-actuated drive member is coupled to the end effector. An electrically controlled variable flow rate pneumatic valve is coupled to the pneumatically-actuated drive member. An electronic control module is coupled to an electrically controlled variable flow rate pneumatic valve to control the flow rate therethrough.

Description

[0001] Cross References to Related Applications [0002] This application is related to the following concurrently filed U.S. patent application, which is incorporated herein by reference: [0003] (1) The title of the invention is "PNEUMATICALLY POWERED SURGICALCUTTING AND FASTENING INSTRUMENT WITH ELECTRICALFEEDBACK", and the inventors are Frederick E.
