Laparoscopic/thorascopic insertion caps
First Claim
1. A laparoscopic tool, comprising:
- an operating instrument for engaging a body part within a body cavity having a protective layer, and including a shaft at a distal end thereof;
an insertion cap including a central passage extending inwardly from a proximal end for frictionally receiving and covering said distal end of said operating instrument, said insertion device also including a distal end terminating in a blunt end adapted for insertion through an opening in the protective layer and for protecting said operating instrument during insertion of said operating instrument into the body cavity, said blunt end being unable to pierce the protective layer under human force.

Abstract
A laparoscopic/thorascopic insertion device is inserted into a body cavity and provides a passageway for inserting a laparoscopic/thorascopic clamp, dissector, or other surgical device without the use of a separate trocar. The insertion device includes a cylindrical shaft having a central passage extending inwardly from a proximal end of the insertion device for frictionally receiving a surgical device. A distal end of the insertion device has a conical shape terminating at a blunt tip adapted to safely displace muscle fibers, blood vessels, and delicate organs and body parts. In a preferred embodiment, the distal end is provided with a gripping area or region that can be engaged by a removal tool that initially is directed through a trocar inserted into the body cavity at an adjacent area of the body cavity.

9. A method for using a laparoscopic tool to access a body part within a body cavity of a patient, comprising
(a) connecting a central passage of an insertion cap with a shaft or distal end of an operating instrument, the combination of the insertion cap and the operating instrument forming the laparoscopic tool; -
(b) splitting a covering of the body cavity to form a first opening in the covering with a separate cutting instrument;
(c) inserting the insertion cap and a portion of the operating instrument through the covering and into the body cavity;
(d) separating the insertion cap from the operating instrument within the body cavity; and
(e) removing the separated insertion cap from the body cavity. - View Dependent Claims (10)

11. A laparoscopic tool, comprising:
-
an operating instrument for engaging a body part within a body cavity, and including a shaft at a distal end thereof;
an insertion device adapted for providing a passageway to the body part, said insertion device including a central passage extending inwardly from a proximal end for frictionally receiving said distal end of said operating instrument, said insertion device also including a distal end terminating in a sharp end for punctuating a covering of the body cavity for insertion of the insertion device and the operating instrument into the body cavity;
a trocar adapted for insertion through the covering of the body cavity to provide another passageway; and
a removal tool adapted for insertion through said trocar to separate said insertion device from said operating instrument. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
