Trocar assembly
First Claim
1. A trocar assembly structured to facilitate fluid flow and disposition of medical instrumentation into and out of a body cavity of a patient, said trocar assembly comprising:
- a) a housing including a hollow interior and a first open end, b) a valve member movably mounted within said hollow interior, c) a valve structure rotatably connected to said housing adjacent to said open end and including a valve seat, d) said valve seat connected to said valve structure and rotatable therewith within said hollow interior relative to said valve member, e) said valve member disposed in substantially continuous engagement with said valve seat and into and out of fluid sealing engagement with said valve seat dependent on an orientation of said valve seat relative to said valve member, and f) said valve member and said valve seat disposable between a valve-open position and a valve-closed position upon selective rotation of said valve structure relative to said housing.

Abstract
A trocar assembly structured to regulate fluid flow as well as the introduction of predetermined medical instrumentation into and out of a body cavity of a patient during a surgical procedure such as, but not limited to laparoscopy, endoscopy, etc. The trocar assembly includes a housing having a hollow interior secured at one end to an elongated open ended sleeve through which fluid flow and medical instrumentation passes. A valve assembly includes a valve member disposed within the hollow interior and a valve structure including a valve seat rotatably connected to the housing such that the valve seat is selectively rotatable relative to the valve member and into and out of fluid sealing engagement therewith so as to respectively define a valve-closed position and a valve-open position. The valve assembly may be rotated between the aforementioned open and closed positions utilizing one hand of the person operating the trocar assembly, wherein the valve assembly will automatically remain either in an open or closed position, without continuous pressure being exerted thereon by the personnel operating the trocar assembly.
