Abstract:
1. A laparoscopy tool, comprising: a small diameter sheath having a lumen; said small diameter sheath having an external diameter of about 1.6 mm or less; a control wire slideably disposed within said lumen; a handle having a fixed position pall engaged to said small diameter sheath and a movable part engaged to a proximal end of said control wire for axially displacing said control wire within said lumen in either axial direction; a tip having a breadth greater than 1.6 mm having opposed jaws that open and dose as said control wire is displaced within said lumen; said tip being positioned at a surgical site by a laparoscope having a large diameter sheath through an incision formed in the umbilicus of a patient, said large diameter sheath having an external diameter that exceeds 1.6 mm; said small diameter sheath and control wire being positioned at said surgical site through an incision formed in an abdominal wall of said patient; said small diameter sheath and control wire being releasably connected to said tip so that said small diameter sheath and control wire are retracted through said abdominal incision and said tip is retracted through said umbilicus incision when a surgical procedure is completed, further comprising: a bore formed in a tubular trailing end of said tip; a first and a second blade, formed of a flexible and resilient material, mounted within said bore in diametrically opposed relation to one another and extending radially inwardly towards a longitudinal axis of symmetry of said bore, said first and second blades having a common length and having radially innermost ends that are spaced apart from one another by a space having less breadth than said control wire so that radially innermost ends of said blades are momentarily displaced in a proximal-to-distal direction when said control wire is inserted into said bore; and a first groove formed in a leading end of said control wire on a first side thereof and a second groove formed in said leading end of said control wire on a second side thereof said first and second grooves being transversely disposed relative to a longitudinal axis of said control wire and said first and second grooves respectively receiving said first and second blades when said control wire is inserted into said bore, said first and second blades snapping into said first and second grooves, respectively, under their inherent bias after said momentary displacement.
