Attorney, Agent or Firm:
A surgical apparatus and method of use is provided for applying and maintaining a securing member upon a length of suture material which extends from body tissue. The apparatus essentially comprises a handle assembly, and elongated housing extending distally from the handle assembly and a tool assembly preferably detachably connected to a distal end of the body portion and remotely operable from the handle. The tool assembly enables a surgeon to compress and maintain a securing member upon suture material in the body cavity while also providing means to cut unsecured suture material which extends from the compressed securing member. Additionally, an instrumentation kit is provided which includes the surgical apparatus and at least one additional tool assembly, as mentioned above, in cooperation with a top cover portion and a bottom cover portion. |

DETAILED DESCRIPTION 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, should not be construed to limit the present invention to apparatus for use only in conjunction with an endoscopic tube.
To the contrary, it is believed that the present invention may find use in procedures wherein access is limited to a small incision, such as, for example, arthroscopic procedures.
The present invention provides a novel surgical apparatus for securing the ends of a suture, and more particularly, for compressing a securing member about a loop of suture material.
Briefly, the present invention enables the surgeon to bring about a desired tension upon a length of suture material, and maintain that tension by compressing a securing member upon the suture material thus replacing the need for knotting the suture material.
The surgical apparatus of the present invention includes a handle assembly having actuation structure and an elongated body potion extending from the handle assembly.
An atraumatic tool assembly is connected to a distal end portion of the elongated body portion for compressing a preformed securing member.
The atraumatic tool assembly is remotely operable from the handle assembly for enclosing and compressing a securing member.
The apparatus may also include a cutting blade for curing a length of suture material which extends from the compressed securing member.
In one method of use, first the surgeon connects a tool assembly having a securing member releasably disposed in the elongated body portion and brings the two ends of a suture extracorporeally, via a cannula assembly which enables the surgeon to thread the suture ends through the securing member using a conventional threading tool.
The surgeon, while grasping the ends of the suture threaded through the securing member, inserts the tool assembly and a portion of the endoscopic body into the body cavity, via a cannula assembly, into approximation with body tissue having the sutures extending therefrom
