Visually directed trocar for laparoscopic surgical procedures and method of using same
First Claim
1. A surgical penetration device comprising:
- a) an inflexible elongated member having first and second opposite ends and an inside space,b) a light transmission and imaging member affixed to and extending beyond said first end of said inflexible elongated member and being formed essentially of transparent material to project light and receive light images,c) a piercing edge for said light transmission and imaging member cooperable with said light transmission and imaging member, andd) the second end of said elongated member being open and the open second end and the inside space being of respective predetermined size to permit detachable slidable insertion of a conventional lighting member and a conventional light image receiving member in the form of a conventional light telescope into the inside space from the open second end of the elongated member, and slidable removal of the conventional light telescope from the open second end of the elongated member, whereby said light transmission and imaging member is cooperable with said conventional light telescope when said conventional light telescope is inserted in said elongated member.

Abstract
A new and improved laparoscopic trocar and sleeve assembly in which the trocar is provided with a transparent tip that can include a blade edge 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.

15. A method of visualizing insertion of a surgical device through flesh into a body cavity comprising the steps of:
-
a) providing an inflexible elongated member with an interior space, b) attaching a light transmission and imaging member formed essentially of transparent material at one end of the elongated member and providing an opening at a second opposite end of said elongated member, c) providing a piercing edge for cooperation with the light transmission and imaging member to pierce flesh and permit insertion of the light transmission and imaging member through the pierced flesh into a body cavity, d) slidably locating a conventional lighting member and a conventional light image receiving member in the form of a conventional light telescope in the opening at the second end of the elongated member to locate the conventional light telescope proximate said light transmission and imaging member in the interior space of the elongated member to enable light from the conventional light telescope to project outwardly away from said light transmission and imaging member and to permit the conventional light telescope 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, whereby said light transmission and imaging member provides a receivable image for the conventional light telescope of the flesh and body cavity being entered, and e) keeping the conventional light telescope in the elongated member in a manner that permits slidable removal of the conventional light telescope from the operating at the second end of the elongated member when the elongated member is removed from the flesh. - View Dependent Claims (16, 17, 18, 19, 20, 21)
