Abstract
Abstract A thigh restraining apparatus especially useful in connection with arthroscopic knee surgery wherein the surgeon may perform the operation while viewing the knee on a television screen. A bar member extends across the operating table supported by horizontally extending rail members customarily provided on operating tables. A specially designed sphygmomanometer constitutes a tourniquet member and applies a known pressure to the thigh of the patient. A strap member envelops the thigh of the patient and is reeled out or in by a screw feed as required to accommodate the patient's thigh. One end of the strap is secured and an intermediate portion is removably attached to the sphygmomanometer. If necessary, both knees may be operated upon sequentially without disturbing a required sterile field by positioning a pair of strap feeding devices on opposite sides of the bar member and securing each strap to an adjacent sphygmomanometer applied to each of the patient's thighs.
