Natural orifice surgical system

摘要

A system for performing minimally invasive medical procedures through a natural orifice includes an elongate support advanceable in a flexible state through a natural orifice and through an incision in a body organ into a body cavity. The elongate support is convertible to a rigid state within the body cavity. The elongate support supports a frame that carries a pair of tool cannulas, each of which has a lumen for receiving a tool useable to perform a procedure in the body cavity. The frame is expandable to orient the tool cannulas such that they allow the tools to be used in concert to carry out a procedure at a common location in the body cavity.
