1. A surgical penetration device comprising:
- a) an inflexible elongated member having a first end,b) light transmission and imaging means provided at the first end of said elongated member to project light and receive light images,c) said light transmission and imaging means including means for piercing human flesh to permit surgical insertion of said light transmission and imaging means through human flesh into a body cavity,d) said light transmission and imaging means being affixed to said first end of said inflexible elongated member,e) said elongated member having means for containing a lighting means and a light image receiving means to cooperate with said light transmission and imaging means, andf) handle means joined to said elongated member to permit one-handed manipulation of said elongated member and to permit the same one hand to simultaneously exert manual pressure on said elongated member in the direction of said light transmission and imaging means for surgical insertion of said light transmission and imaging means through human flesh into a body cavity.

Abstract
A new and improved laparoscopic trocar and sleeve assembly in which the trocar is provided with a transparent tip and accommodates a light telescope for supplying a video console so that while the trocar is being surgically inserted through the abdominal wall and into the abdominal cavity, visualization on the video console will be possible to avoid injury to blood vessels in the abdominal cavity wall or injury to any of the internal organs located in the abdominal cavity. A handle provided on the trocar facilitates manipulation and control of the trocar tip penetration. Once clear visualization is established, conventional laparoscopic procedures can be carried out safely.

11. A method of visualizing insertion of a surgical device through flesh into a body cavity comprising the steps of:
-
a) providing a novel hollow trocar with a tubular body and a light transmission and imaging member with means for piercing human flesh for surgical insertion through human flesh, b) joining said light transmission and imaging member to one end of said tubular body formed of a biocompatible material, c) joining a handle member to the tubular body proximate an opposite end of the tubular body to manipulate said trocar and to exert manual pressure on said trocar in the direction of said light transmission and imaging means for surgical insertion of said light transmission and imaging means through human flesh into a body cavity, and d) locating a conventional lighting means and light image receiving means in said hollow trocar proximate said light transmission and imaging member to enable light from the lighting means to project outwardly away from said light transmission and imaging member and to permit the light image receiving means to receive light images that pass from outside said light transmission and imaging member through said light transmission and imaging member while said light transmission and imaging member is being inserted through the flesh into a body cavity during manipulation of the trocar by the handle member, whereby said light transmission and imaging member provides a receivable image of the flesh and body cavity being entered. - View Dependent Claims (12, 13, 14, 15)
