摘要:
Certain aspects of the present disclosure provide a low friction trocar valve comprising a set of sheets arranged circularly and defining an entry point for the insertion of an instrument. In certain aspects, each sheet of the trocar valve's set of sheets comprises areas that overlap with two adjacent sheets. The trocar valve is formed in an opening of a valve housing coupled to or formed as part of a trocar cannula to provide a sealing mechanism for preventing the escape of pressurized fluids from the trocar cannula.
