Spinal-surgery table

Abstract

A patient support device for supporting a patient at four points during back-related surgery. The device includes a generally rectangular frame having two opposing end members and two opposing side members. Two front posts are slidably mounted to one of the two end members. A travelling member is slidably mounted to both side members and may be displaced in a longitudinal direction between the two end members. Two rear posts are slidably mounted to the travelling member and may be displaced therealong, in a transverse direction between the side members. A front lead screw assembly is connected to the two front posts and allows simultaneous and opposing displacement of both front posts along the end member so that both front posts may be moved an equal distance from a center axis. Similarly, a rear lead screw assembly is connected to the two rear posts to allow simultaneous and opposing displacement of both rear posts along the travelling member. Each post includes a U-shaped channel to collectively accommodate a film cassette used in radiography. A conforming cushion is positioned above each post for contacting the patient.
