Device and method for the positioning of tissue during laparoscopic or endoscopic surgery

摘要

A surgical device and method for the retracting, maneuvering, and re-positioning of tissue and/or a body organ during endoscopic and laparoscopic procedures. The surgical apparatus comprises at least one separable grasping device with a detachable head, and an exteriorly-operated handle mechanism, or puppet handle. The disclosed device enables a physician, using a plurality of lengths of sutures simultaneously connected to (a) stems of the exteriorly exposed puppet handle and (b) the detachable head, positioned at clasping points on the organ, to rearrange the orientation of tissue or the organ for better accessibility, analysis, and/or exposure to accompanying surgical instruments in situ. The method presented minimizes the number of bodily incisions required to perform surgery by means of endoscope or laparoscopic equipment.

主权项

1. A surgical apparatus for retracting, re-positioning, and re-orienting tissue or a bodily organ during endoscopic or laparoscopic procedures, comprising
a) a detachable grasping head comprising an upper jaw and a lower jaw, said jaws being attached to a grasper head housing wherein a tensioned locking ring is attached to the perimeter of said grasper head housing, with a driven shaft attached to and concentric with the center of said grasper head housing; and b) a grasping handle having a proximal end and a distal end proximate said grasper head, and further comprising a hollow longitudinal sleeve, said longitudinal sleeve housing a drive shaft, which drive shaft connects, at the proximal end of the longitudinal sleeve, to a control wheel, and further, said drive shaft having at its distal end an expanded u-joint interiorly containing a plurality of spring-loaded balls, wherein said control wheel, when activated by a user, turns a driven shaft, said driven shaft being attached by a square fitting to said grasper shell; and c) a puppet handle comprising (i) a primarily cylindrical structure having a hollow left end and a hollow right end, wherein a compressible material is firmly compacted within the interior of said hollow left end and said hollow right end, said compressible material of such frictional coefficient as to enable the retention of at least one surgical needle inserted into said compressible material; and (ii) two exteriorly-attached, co-axial, flexible c-ring clips, each clip of an inner diameter corresponding to the outer diameter of said grasping handle.
