초록 ▼

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.

대표청구항 ▼

A trocar assembly, comprising: a) a reusable cannula assembly including a cannula base having a first coupling means, and a hollow cannula extending from said cannula base, said cannula base defining a first fluid passage in fluid communication with said hollow cannula; b) a disposable valve assembly having a valve body defining a second fluid passage, said valve body including a fluid valve means in fluid communication with said second fluid passage, and a second coupling means for removably coupling said disposable valve assembly with said first coupling means of said reusable cannula assembly to effect a fluid coupling of said first and second fluid passages; and c) a trocar insertable through said cannula, said trocar having a proximal handle, wherein, said first and second fluid passages and said cannula are dimensioned to permit said trocar to be inserted therethrough, said fluid valve means for permitting said trocar to be inserted through said valve means, for forming a seal between said trocar and said second fluid passage when said trocar is inserted through said valve means, and for automatically sealing said second fluid passage when said trocar is removed from said valve means, and one of said cannula assembly and said disposable valve assembly includes a fluid sealing means for sealing said first and second fluid passages together.
