ABSTRACT:
A device and method for creating sterile surgical access to internal body parts through a natural opening of an internal body cavity are disclosed. The device includes an elongate body member with a distal end that is inserted into the natural body opening and at least one channel that extends along the length of the body member. One of the channels, a wash channel, carries a cleansing fluid which is ejected through nozzle jets to wash a portion of a wall of the internal body cavity. The wash channel is also operatively associated with a vacuum source so that suction through the nozzle jets results in a fluid-tight connection between the distal end of the body member and the portion of the wall. A perforation channel having a deformable inflation member located between the proximal and distal ends of the channel when not inflated to maintain its sterility is inflated to extend beyond the distal end of the body member. A perforation element on the inflation member creates a hole in the portion of a wall through which a part of the deformable inflation member can extend to assume a shape having at least a section larger than the hole's diameter. Surgical instruments can be inserted in the proximal end of the body member for manipulation and visualization of the internal body parts at the distal end of the body member.
