Abstract

A unique laparoscopy instrument tip and method which allows simultaneous gasping, cauterization, dissection, containment, enclosure and removal of body tissue. Mechanisms for grasping, holding, manipulating, cauterizing, dissecting, encasement in an enclosed cavity and removing the tissue are provided in one implement allowing easy, safe and quick performance of the procedure.

Claims

1. A tip for a bipolar laparoscopy instrument comprising:

a fixed jaw with a raised outer edge, which is configured to be connected to a power source for bipolar cautery;

a movable ring shape jaw, which comprises a hollow interior and configured to be connected to a power source for bipolar cautery; and

a movable cup shape cutting jaw, wherein (a) the movable ring shape jaw and fixed jaw exhibit the same width, (b) the cutting jaw exhibits a width that is less than a width of the ring shape jaw, (c) the ring shape jaw is positioned between the fixed jaw and the cutting jaw, and (d) the fixed jaw and cutting jaw, when in a closed position, are configured to encase and protect dissected tissue until it is removed from a body.

2. A laparoscopy instrument tip as in claim 1, which allows simultaneous manipulation, cauterization, dissection, encasement and removal of an entire specimen of body tissue.

3. A laparoscopy instrument tip as in claim 1, which prevents slippage of body tissue during a laparoscopic procedure.

4. A method of dissecting tissue comprising:

grasping the tissue, cauterizing, dissecting, encasing and removing a specimen of tissue with the laparoscopy instrument tip of claim 1.
