Problems solved by technology

Known prior art surgical staplers are lacking in several respects.
Firstly, the use of multiple actuators to effect approximation and firing of the instruments complicate the manufacture and operation of the instrument and, in most cases, require the surgeon to use two hands to hold and operate the instrument

Embodiment Construction

[0062] Preferred embodiments of the presently disclosed surgical stapling device will now be described in detail with reference to the drawings, wherein like reference numerals designate corresponding elements in each of the several views.

[0063] The presently disclosed surgical stapling device shown generally as 10 in FIGS. 1-3 includes a body 12 defining a stationary handle 14, a pivotable trigger 16, an elongated central body portion 18, a cartridge assembly 20 and an anvil assembly 22. A thumb button 24 is slidably positioned on each side of body 12. Thumb buttons 24 are movable to manually advance an alignment pin assembly in a manner to be described in detail below. A release button 150 of release mechanism 26 is positioned on the proximal end of body 12 and is depressible to allow cartridge assembly 20 to return from an approximated position disposed adjacent to anvil assembly 22 to a position spaced from anvil assembly 22 (as shown). Operation of release mechanism 26 will al...

Abstract

A surgical stapling device for applying an array of surgical staples to tissue is provided. The stapling device includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly. A single trigger is operable to effect approximation and firing of the device. The device also includes an alignment pin assembly which can be selectively manually or automatically advanced. The anvil assembly includes a stiffener plate which allows the device to have a reduced head portion profile.

Description

[0001] This application is a continuation of U.S. patent application Ser. No. 10 / 783,126, filed on Feb. 20, 2004, which is a continuation of U.S. patent application Ser. No. 09 / 687,815, filed on Oct. 13, 2000. Each of which is incorporated herein in its entirety by reference.BACKGROUND [0002] 1. Technical Field [0003] The present disclosure relates generally to a surgical stapling apparatus and, more specifically, to a surgical stapling apparatus having a single trigger for approximating anvil and cartridge assemblies and for ejecting an array of staples from the cartridge assembly. [0004] 2. Background of Related Art [0005] Surgical stapling instruments used for applying parallel rows of staples through compressed living tissue are well known in the art, and are commonly used, for example, for closure of tissue or organs prior to transection, prior to resection, or in anastomoses, and for occlusion of organs in thoracic and abdominal procedures. [0006] Typically, such surgical stap...
