This invention proposes an intelligent orthopedic traction system. The system includes a motion monitoring sleeve, a traction sleeve, a traction force adjustment module, and a control module. The motion monitoring sleeve and the traction sleeve are connected via a motion sensing module, and the traction sleeve is connected to the traction force adjustment module via a traction rope. The motion monitoring sleeve is fitted over the upper end of the traction area of ​​the affected limb, and the motion sensing modules are symmetrically arranged on both sides of the traction sleeve. The traction sleeve wraps around the traction area of ​​the affected limb and detects the physiological parameters of the traction area. The control module receives detection data from the motion sensing module and the traction sleeve, determines whether traction abnormalities have occurred, controls the traction force adjustment module based on the abnormalities, and notifies medical personnel of the abnormalities. In this invention, abnormal situations during the orthopedic traction process are monitored in real time by sensors, and emergency measures are taken based on these abnormalities, notifying medical personnel for timely intervention, thus reducing the workload of medical personnel while improving the speed of response.

The invention relates to a traction frame of a Braun orthopedic traction device, which comprises a traction frame, a frame wheel, a traction rope, a traction power device and a traction bow. The traction frame is adjusted in front and back by a locking part from the bottom relative to the leg rest frame. The height of the frame top is adjusted by the extension and contraction of the left and right sides of the traction frame. The frame wheel comprises a first, second and third pulley group. The traction rope comprises a first, second, third and fourth section. The invention adjusts the position and direction of the traction bow based on the height and angle of the traction frame without adjusting the leg position again, which reduces the difficulty of traction. The length and angle of the four sections of the traction rope cooperate, which not only continuously tractions in the dynamic balance mode, but also changes the traction force while keeping the traction position and angle unchanged, which improves the traction direction and the mechanical axis, thereby reducing the risk of traction injury.
