Benefits of technology

An apparatus is disclosed for applying latchless surgical clips to body tissue. The latchless clips each possess a pair of legs movable between a closed position wherein the legs are in relatively close proximity to each other and an open position wherein the legs are relatively spaced apart from each other. The legs are resiliently biased to the closed position. The apparatus comprises frame means, and endoscopic means of generally elongated configuration connected to the frame means and extending distally therefrom. The endoscopic means includes: means for storing a pl

1. Preface

In the following description it should be noted that such terms as "distal" and "proximal", "upper" and "lower", "horizontal" and "vertical", "above" and "below", are used relative to each other and do not refer to positions or orientations relative to a frame of reference external to the apparatus.

Because endoscopic procedures are more common than laparoscopic procedures, the present invention shall be discussed in terms of endoscopic procedures and apparatus. However, use herein of terms such as "endoscopic", "endoscopically" and "endoscopic portion", among others refer generally to instruments having elongated and relatively narrow operating portions for

inserting into a cannula, body opening, or small wound in the skin and should not be construed to limit the present invention to an apparatus for applying surgical clips only in conjunction with an endoscopic tube. To the contrary, the present invention may find use in any procedure where access is limited to a small inc...

Abstract

A disposable apparatus is disclosed for applying latchless surgical clips to body tissue in endoscopic surgical procedures. The latchless clips are resiliently biased to a closed configuration. The apparatus includes a frame which is adapted to be gripped by hand, and an endoscopic section connected to the handle and capable of storing surgical clips in preparation for clipping arteries or other body tissue. The apparatus includes means for advancing each clip sequentially, temporarily opening the clip and advancing the clip further to a pair of distal jaws where the clip is positioned around the body tissue and closes around the tissue. Also included are means for closing the jaws about the clip. When the jaws are closed, the clip advancing means is simultaneously positioned to advance the next clip. The present apparatus also makes it possible to partially close a clip without interfering with the sequential movement of the clip advancing mechanism.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to an apparatus and method for applying surgical clips, especially hemostatic clips, to body tissue such as blood vessels. More particularly, this invention relates to a surgical clip applier which can be used in laparoscopic or endoscopic procedures for closing ducts, arteries and the like, and to a method for using same.2. Background of the ArtIn surgical operations it is often necessary to apply hemostatic clips to blood vessels, and apparatus for applying clips are known in the art. See, for example, U.S. Pat. No. 4,616,650 and 4,624,254, both of which are hereby incorporated by reference in their entirety, which disclose asurgical clip applying apparatus having ring-like handles. The handles are squeezed to force jaws to move distally relative to the apparatus where they are forced together by a pair of inclined surfaces. A surgical clip between the jaws is thereby squeezed closed.While the instruments d...
