Embodiment Construction

[0100] Referring to the drawings, wherein like reference numerals denote like parts throughout, figure 1 A disposable loading unit 16 of the present invention is depicted that may be used in conjunction with a surgical stapling device such as that disclosed in US Patent No. 5,865,361, the disclosure of which is incorporated herein by reference. It will be understood that the terms "proximal" and "distal" are used herein with reference to a clinician grasping the handle assembly of the surgical stapling apparatus to which the disposable loading unit 16 is attached. Thus, the disposable loading unit 16 is distal with respect to the more proximal handle assembly. It will further be understood that spatial terms such as "vertical," "horizontal," "upper," "lower," "right," and "left" are used herein with respect to the drawings for convenience and clarity. However, surgical instruments can be used in many orientations and positions, and these terms are not meant to be limiting and...

Abstract

A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a spent cartridge indication system for providing an indication of whether the loading unit has been previously fired. Other embodiments are disclosed that employ a blade monitoring system for providing feedback to the user concerning the amount of strain being experienced by the blade during cutting and stapling.

Description

[0001] Commonly owned patent applications [0002] The disclosure of Steven G. Hall et al., US Patent Application, filed on the same date herewith, Attorney Docket No. END6216USNP / 070333, entitled "Disposable Loading Unit With Firing Indicator," is incorporated herein by reference. technical field [0003] The present invention relates generally to endoscopic surgical instruments, including but not limited to surgical stapling instruments having a disposable loading unit capable of applying staple lines to tissue while cutting tissue between those staple lines, and more particularly Said, relates to improvements concerning such disposable loading units. Background technique [0004] 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 precis...
