Problems solved by technology

Obstruction based on the position of the plunger valve on the trocar assembly often causes the physician to place his or her hand in compromised or suboptimal positions
Additionally, current valves are prone to accidental operation during the process
In addition, accidental manipulations often occur, resulting in drainage of body cavity fluid, and can lead to failure and even dangerous situations when the surgeon's view is obstructed

Embodiment Construction

[0044] Detailed embodiments of the present invention are disclosed herein. It is to be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be practiced in various ways. Therefore, nothing disclosed herein is to be interpreted as limiting, but merely as a basis for the claims and as a basis for teaching one skilled in the art how to make and / or use the invention.

[0045] There is disclosed a trocar assembly with a piston valve secured to the trocar housing. The plunger valve is mounted on the trocar housing in an inconspicuous manner which overcomes the possibility of the plunger valve getting in the way of the physician's hand and thus affecting his or her control during insertion. The present piston valve further helps to avoid accidental manipulation after insertion and during subsequent medical procedures. Those skilled in the art will certainly understand that the non-contoured piston valve according to the present invent...

Abstract

A trocar assembly includes a trocar sleeve having a trocar housing and a trocar cannula. The trocar sleeve includes a stop-cock valve positioned for selectively controlling the passage of an insufflation fluid into the trocar cannula and the stop-cock valve includes a valve lever. The trocar housing includes a recess shaped and dimensioned for receiving and covering at least a portion of the valve lever therein.

Description

[0001] Referenced related application [0002] This application is based on pending U.S. Provisional Patent Application No. 60 / 506,785, filed September 30, 2003, entitled "Low-Profile Recessed Piston Valve for Trocar Assemblies" . technical field [0003] The present invention relates to trocar assemblies and, more particularly, to a low profile piston valve arrangement for a trocar assembly. Background technique [0004] A trocar assembly is a surgical instrument used to gain access to a body cavity. A trocar assembly typically consists of two main components, a trocar sleeve and a trocar, consisting of a trocar housing and a trocar sleeve. stuffer. A trocar filler is inserted through the trocar cannula, and the trocar cannula is guided through the skin into a body cavity. Once the body cavity has been accessed, laparoscopic or arthroscopic surgical and endoscopic procedures can be performed. To penetrate the skin, the distal end of the trocar cannula is placed against ...
