ABSTRACT:
The present invention provides a clamp which can be used to secure an accessory member to an abductor bar of an orthopedic-surgical table. The clamp includes a clamp block pivotally mounted on the clamp and oriented with respect to the clamp to clamp an object therebetween. A lever having a cam surface is mounted on the clamp so that the cam surface coacts with the internal mechanism of the clamp to orient the clamp block in an unclamped, intermediate and clamped position. When the clamp is in the intermediate position, the clamp loosely engages the clamped object so that relative motion of the clamp and clamped object can occur. Because the clamp can be stabilized on the clamped object by orienting it in the intermediate position the operator does not need to use a second hand to prevent the clamp from falling off the clamped object while the first hand positions and tightens the clamp. Thus, the clamp can be secured to the clamped object in a one handed operation. The position of the lever reflects the position of the clamp block and thus indicates how tightly the clamp is secured to the clamped object.
