Abstract

A self contained motor-powered disposable loading unit for use with a surgical cutting and stapling apparatus. The disposable loading unit may contain a battery that is retained in a disconnected position when the disposable loading unit is not in use and is moved to a connected position when the disposable loading unit is coupled to the surgical cutting and stapling apparatus to permit the motorto be selectively powered thereby. Indicators may be supported on the disposable loading unit to indicate when the axial drive assembly thereof is in a starting position and an ending position. Another indicator may be provided to indicate when the anvil assembly is in a closed position.

Description

technical field [0001] The present invention generally relates to endoscopic surgical instruments, including, but not limited to, surgical cutting and stapling devices with disposable loading units capable of applying staple threads to tissue while cutting tissue between those staple threads, and more In particular, it concerns improvements with respect to such disposable loading units. Background technique [0002] Endoscopic surgical instruments are often preferred over traditional open surgical devices because smaller incisions tend to reduce postoperative recovery time and complications. Accordingly, there has been significant development in the field of endoscopic surgical instruments adapted to precisely place a distal end effector through the cannula of a trocar at a desired surgical site. These distal effectors engage tissue in a variety of ways for diagnostic or therapeutic purposes (e.g., endoscopic cutters, graspers, cutters, staplers, clip appliers, access devic...
