ABSTRACT:
A surgical table for animals has a basic flat top which can serve for the smaller species. To accommodate large animals, extensions are fitted in the form of rigid panels having tongue and groove engagement with selected edge parts of the basic top. They can be clamped in position. The top is carried by folding legs enabling it to be lowered virtually to floor level and raised to operating height. The legs are in variable X-form with a scissor action, the top of one leg being hinged to the underside of the top and the top of the other leg having a sliding or rolling engagement. The adjustment is by hydraulic actuators, the main one, which aligns with the legs when fully folded, being assisted by a starter actuator which acts vertically between the legs and the table top at the beginning of each lift.
