Background

Traction is a commonly used treatment method in orthopedics, and is a treatment method for relieving muscle tension and strong contraction, reducing fracture and dislocation, preventing and correcting soft tissue contracture, and performing preoperative tissue release and postoperative brake on certain diseases by using the weight of suspension as traction force and the body weight as counter traction force through a traction device. Bone traction is an important traction technique, also called direct traction, and is characterized in that a steel needle or a traction forceps is used to penetrate through bone, so that traction force directly passes through bones to reach an injured part, and the functions of restoration, fixation and rest are achieved.

When medical personnel in hospitals carry out bone traction on patients with lower limb fracture, a fixed traction frame is sleeved on a sickbed frame at the tail part of a sickbed, a fixed pulley sleeve fixed through a top pin is arranged on the traction frame, a traction stay cord is wound around the fixed pulley, a weight is fixed at the tail end of the traction stay cord and naturally hangs down by means of gravity, and traction force is provided for the patients through the traction stay cord. When the device is used for traction, the fixed pulley directly bears the gravity of the lower limb of a patient and is easy to fall off, the height of the fixed pulley cannot be adjusted by the device, the angle of the fixed pulley sleeve is inconvenient to adjust, the whole device is inconvenient to use, the device provides traction force through the weight of the balance weight, the balance weight is easy to shake, the traction force is unstable, and secondary injury is easy to cause.
