Embodiment Construction

[0093] 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 carrier that supports a staple cartridge therein, an anvil assembly that is movably coupled to the carrier, and an axial drive assembly that is constructed to move in a distal direction from a start position to an end position through the staple cartridge in response to a drive motion imparted to the axial drive assembly from the surgical stapling apparatus. A firing indicator is provided on at least one of the anvil assembly and housing for indicating a position of the axial drive assembly as the axial drive assembly is driven from the start position to the end position.

Description

[0001] Commonly owned patent applications [0002] The content of the publication of Kevin R. Doll et al.'s U.S. Patent Application No. END62286USNP / 070345 filed on the same date and entitled "Disposable Loading Unit With UserFeedback Features and Surgical Instrument For Use Therewith" is incorporated herein by reference 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 ...
