Method of using reusable surgical trocar with disposable valve assembly |
摘要 |
A surgical trocar assembly includes a disposable valve assembly, a cannula assembly, and a trocar with a handle. The cannula assembly includes a cannula base having a valve assembly coupling device at its proximal end, and a cannula extending from its distal end. The disposable valve assembly has a coupling device for removably coupling it with the cannula base. The valve assembly also includes a valve body with a fluid passage communicating with the hollow cannula when it is coupled to the cannula base. A slit or flapper valve and a universal washer are mounted within the valve body and allow the insertion of the trocar or other endoscopic instruments therethrough while providing a fluid sealing of the fluid passage. The valve assembly may be provided with a side port which optionally contains an automatic valve actuated by a luer coupling. Several different valve assembly-cannula base couplings are disclosed as well as several different types of trocars.
