Abstract

An apparatus that controls the rotation of an operative limb during shoulder surgery is composed of three parts: 1) a mechanism that is part of the durable apparatus, and which allows the limb to be suspended from the system and traction weights applied, but is configured in such a manner that the cable or other connecting member does not rotate about its axis; 2) a sterile connector that acts as the interface between the non-sterile durable apparatus and a sterile patient-contacting disposable drape; and 3) the disposable drape which is secured to the patient's operative arm. One of the sterile connector and the disposable drape contains a feature that allows the physician to rotate and hold the limb in any desired position, without requiring that it be manually held in place.

Dependent claims

A surgical limb positioning apparatus comprising:

an elongated, hollow boom member having a proximal end, a distal end and a longitudinal axis extending therebetween;
a carriage disposed within the boom member and moveable along the longitudinal axis;
a first flexible member attached to a first side of the carriage and exiting the boom member at a first aperture located at the proximal end of the boom member, a free end of the first flexible member configured for attachment to a weight;
a second flexible member attached to a second side of the carriage such that the flexible member cannot rotate relative to the longitudinal axis of the boom member, the second flexible member exiting the boom member at a second aperture located at the distal end of the boom member;
and
a connector assembly attached to a free end of the second flexible member for forming a sterile connection to a drape assembly;
wherein one of the connector assembly and the drape assembly comprises an anti-rotation mechanism configured to maintain an operative limb of a patient in a pre-selected position.
