ABSTRACT:
An auxiliary cavity expanding device for an operation which may prop up a body portion for laparoscopic surgery in order to make space for the performance of the operation includes a plurality of stays and a stay sleeve. The stays are secured to a stay end tube and an end of each stay is provided with a stay pusher to shift the stays relative to the stay sleeve. This shifting causes bending of the stays and expanding of the cavity for the operation. After expansion, the stays can be secured in a desired position by screws which secure the stays relative to the stay sleeve.
