A hand held device allows force to be exerted on a body of a patient without causing muscle fatigue of the hand. Preferably the device is made of a radiolucent material. This device is particularly useful when used to manipulate or depress the abdomen to displace one bowel loop away from another so that tumors or other abnormalities of the gastrointestinal tract can be visualized during fluoroscopy. The device has a lever arm with a wrist cuff at an end of the lever arm and a handle both extending from the lever arm with a compression cone at the end of the lever arm opposite the wrist cuff. The user grips the handle with the wrist cuff resting across the dorsum of the wrist. Pressure is exerted on the abdomen by the cone by volar flexion of the wrist. Additional pressure and sensitivity are obtained by the use of a finger tab extending from the lever arm at a position between the handle and the cone. A thumb rest rib on the handle also improves sensitivity.
