Abstract

A stapling device for a surgical endoscopic device provided with at least one flexible portion, comprising a staple-firing portion and an anvil portion, wherein one of the staple firing portions and one of the anvil portions are located longitudinally displaced from one another along the longitudinal axis of the endoscopic device, with at least a part of said flexible portion between them. The parts of the stapling device are in correct working relationship when one or more alignment and/or locking pins or screws that are stored in one of the staple firing portions or one of the anvil portions are extended and engage and lock or screw into receptacles that have been provided on the other of the staple firing portion or of the anvil portion.

Claims

85. A surgical tissue fastening apparatus, comprising:

(i) a longitudinal member;

(ii) a surgical fastener ejector disposed at a first location along the longitudinal member;

(iii) a non-gripping tissue support disposed at a second location along the longitudinal member; and

(iv) at least one articulation joint disposed at a third location along the longitudinal member between the first and second locations, the at least one articulation joint being configured to enable the tissue support to be moved into opposing relationship to the surgical fastener ejector.

86. Apparatus according to claim 85, further comprising an optical channel disposed along the length of the longitudinal member.

87. The apparatus of claim 85, wherein:

(i) the non-gripping tissue support defines a void that is positionable in opposing relationship to the surgical fastener ejector upon articulation of the longitudinal member about the joint; and

(ii) the surgical fastener ejector is configured to eject a surgical fastener toward the void.

88. The apparatus of claim 87, further comprising at least one surgical fastener in the surgical fastener ejector.

89. The apparatus of claim 87, further comprising a holding mechanism configured to hold the non-gripping tissue support at a fixed distance from the surgical fastener ejector.

90. The apparatus of claim 85, further comprising a mechanical linkage configured to forcibly urge the non-gripping tissue support toward the surgical fastener ejector, whereby biological tissue disposed between the non-gripping tissue support and the surgical fastener is restrained.

91. The apparatus of claim 85, wherein the surgical fastener ejector is a staple firing device.

92. The apparatus of claim 88, wherein the surgical fastener is a surgical staple and the fastener ejector is a staple firing device.

93. The apparatus of claim 92, wherein the surgical staple has legs, the void has a thickness, the depth of the void is less than the thickness of the support and the portion of the tissue support defining the bottom of the void is configured to bend the legs of the surgical staple upon actuation of the staple firing device and a resulting contact of the surgical staple with the bottom of the void.
