Abstract
And arthroscopy support stand is disclosed which contains, in a single movable unit, all of the apparatus needed to perform arthroscopic surgery. The stand comprises a wheel-mounted steel cabinet with brakes at the back of the cabinet for immobilizing it. The cabinet has shelves, open at the front, for supporting various arthroscopic surgery appliances. Mounted at the back of the cabinet are two upright, vertically telescoping fluid bag standards which can be lowered separately to change fluid supplies without interrupting the flow of fluid under pressure to the surgical site. A vertical support column is mounted at the front of the cabinet on a pair of vertically-spaced parallel horizontal arms. The arms are pivotally mounted at the middle of the cabinet so that the support column can be shifted back and forth across the front of the cabinet. The support column has a telescoping upper portion supporting a boom from which a television camera is suspended by an extensible cable counterweighted in the support column. A pair of articulated support arms are mounted one above the other on a lower portion of the support column for vertical and rotational movement to support a television monitor on one arm and an instrument tray on the other. The support arms can be moved up and down on the support column. The television monitor support arm is suspended via pulleys extending into the lower portion of the support column alongside the counterweight to connect under tension to a vertically-extensible coil spring positioned concentrically around the counterweight.
