Abstract
An access device for surgical procedures includes a multiport end cap including a plurality of separate access ports for accommodating introduction of individual surgical instruments into the body of a patient. The access ports extend in a proximal direction. The end cap includes a distally extending seal ring. A bottom body has a distally extending tubular body with an access channel defined therethrough for accommodating surgical instruments from the access ports into the body of a patient. The bottom body includes a plurality of circumferentially spaced apart teeth, wherein the seal ring of the end cap is received inside and seals against a proximal rim of the bottom body. The end cap includes at least one flexible tab with distal teeth thereon configured to engage and disengage the teeth of the bottom body to selectively permit or prevent relative axial rotation of the multiport end cap.
