    (54) Adjustable support device for surgery


    (57) An adjustable patient support which is particularly useful in spinal surgery, comprises a base (10), first and second support members (32,34) extending upwardly from the base and being slidably located in an elongate guide (26) in the base. A threaded bar (62) is mounted for rotation about its longitudinal axis which is aligned parallel to the longitudinal axis of the guide (26), and is provided with two portions threaded in opposite senses. Each threaded portion is received in a complementarily-­shaped recess in a respective one of the support members (32,34), whereby rotation of the bar causes relative movement of the two support members along the guide groove. The support members each comprise a base portion and a patient engagement portion, and there are means for adjusting the height of the patient engagement portion.
    The invention permits unobstructed access to the spine, and since the majority of the weight of the patient is supported on the device, the blockage of arteries and veins is alleviated or prevented. The device also allows an anaesthetist to check that the patient is still breathing, by feeling the movement of the patient's abdomen.
