Winch mechanism for orthopedic traction bed

Abstract

The winch mechanism comprises the orthopedic traction bed, a support is installed on the orthopedic traction bed, a hanging ring is suspended on the support, an installation box is fixedly installed on the bed side of the orthopedic traction bed, a winding shaft is rotationally connected to the side wall of the installation box, one end of the winding shaft is rotationally connected with a fixing plate, and the other end of the winding shaft is rotationally connected with a rotating shaft. The fixing plate is fixedly connected to the bed bottom of the orthopedic traction bed, the other end of the winding shaft extends into the mounting box, a pull rope is wound around the winding shaft, a plurality of guide wheels are mounted on the support, the pull rope is in bolted connection with a hanging ring after passing through the guide wheels, the extending end of the winding shaft is fixedly connected with a gear and a ratchet wheel, and the ratchet wheel is fixedly connected with the gear. A rotating shaft is rotationally connected into the mounting box through a torsion spring, and a pawl matched with the ratchet wheel is mounted on the rotating shaft. The device adopts a brand-new winding and unwinding mode, the hanging ring can be driven to rise only by moving the hand of a patient back and forth in a small range, the hanging ring can be put down by rotating the knob, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of orthopedic traction beds, in particular to a capstan mechanism for orthopedic traction beds. Background technique [0002] For patients with calf fractures or other lower limb diseases, due to the difficulty in moving the lower limbs, maintaining a posture for a long time is not conducive to the rehabilitation of the lower limbs, and it is easy to cause joint stiffness, muscle spasm, and even skin necrosis. Clinically, traction beds are often used to help patients Rehabilitation of the lower extremities. [0003] After the patient lies flat, the lower limbs are hung on the suspension ring, and the suspension ring is generally lifted by a winch. Most of the winches are in the form of a turning handle. It is necessary to have a large enough range of motion to turn the handle. For some patients with limited mobility, it is difficult to operate by themselves. Contents of the invention [0004] In view of ...
