Abstract

Apparatus for use in surgery comprises a sleeve (1) having an entry opening (4) at an outer end and an exit opening. (5) at an inner end to access a patient'"'"'s body. Exit sealing means 10 are provided for sealing the exit opening (5) to a body entry sealing means (20) are provided for sealing the outer entry against an arm passing therethrough to create a controlled environment within the sleeve.

A valve (101) comprises an outer ring (105,106) and a sealing sleeve (107) of flexible material mounted to the ring (105,106) and extending into the opening defined by the ring to terminate in a substantially centrally disposed inlet opening (108). Through the opening (108) a member such as a trocar (103) or surgical instrument may be passed. The sealing sleeve (107) remains in sealing engagement, with the member (103) as it is passed therethrough.
