Method of using a laparoscopic retractor
First Claim
1. A method for applying intracorporeal traction on an internal body member in a body cavity having a laparoscopic trocar inserted thereinto proximate the body member, comprising:
- puncturing the body cavity wall with a sharp instrument to form a needle hole;
inserting a first end of an acuminate instrument through the needle hole into the body cavity;
inserting a sling through the trocar into the body cavity;
placing said sling about the body member within the body cavity;
extending the acuminate instrument to grasp the sling; and
drawing the sling with said acuminate instrument to retract the body member toward said needle hole.

Abstract
A retraction method and apparatus therefor are useful in laparoscopic surgery in a body cavity, for moving an internal organ or vessel which interferes with the surgery to an out-of-the-way displaced position and maintaining it there apart from a laparoscopic port. In this method, a sling having attached suture material is inserted into the body cavity through a laparoscopic port and manipulated about the organ/vessel to be moved, by a retractor and/or forceps. A small needle hole is then punctured into the cavity, a narrow retrieval instrument is inserted through the needle hole to retrieve the ends of several suture leads attached to the sling, and to retract them from the body cavity to move the interfering organ or vessel to a non-interfering position. The suture leads may be clamped or tied off outside the body. Tools useful with the method include a sling, a retrieval instrument and a J-hook passer-retractor.

3. A method for moving an internal body member to a displaced position in a laparoscopic surgical operation within a body cavity, comprising:
-
inserting a miniature sling having attached leads through a laparoscopic port into a body cavity; manipulating the sling and leads to embrace a body member; inserting a thin acuminate instrument through a needle hole into the body cavity; attaching the leads to the thin acuminate instrument; and retracting the instrument and leads through the needle hole to move the internal body member to a displaced position. - View Dependent Claims (4)

5. A method in laparoscopic procedures for moving an internal body member from an original position to a displaced position within a body cavity and maintaining the member in the displaced position, comprising:
-
establishing a plurality of laparoscopic ports across a wall separating the body cavity from external the cavity; inserting body member embracing means having lead means attached thereto through a laparoscopic port into the body cavity; inserting a laparoscopic retraction tool through a laparoscopic port and manipulating said embracing means about the body member with said retraction tool; establishing a needle hole through the wall into the body cavity, said needle hole located for drawing said embracing means and the body member to a displaced position; inserting retrieval tool means through said needle hole into the cavity and retrieving said lead means therewith; retracting said retrieval tool means and attached lead means through the needle hole to draw the embracing means and body member to a displaced position; and fixing said lead means external of the body cavity to external fixing means to maintain said embracing means and the body member in said displaced position. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
