[0002] A fracture refers to a partial or complete interruption or loss of the integrity or continuity of bone or cartilage tissue when the bone or cartilage tissue is subjected to violent action. Fracture reduction is the process by which a doctor or relevant professional reduces the fractured part of a patient by docking. In the prior art, after the doctor reduces the patient using a point reduction forceps, a series of positioning devices are needed to position the reduced fractured part of the patient to facilitate subsequent bone drilling operations.

[0003] For example, publication number CN216455262U is specifically a fracture reduction and positioning device for orthopedics, including a positioning plate, a movable component is horizontally arranged on the positioning plate, and the movable component is connected to the positioning plate through a guide component, a clamping component, and the clamping component is connected to the movable component, and a pre-fixing component is arranged in the movable component. When the fracture part of the patient is clamped by the pre-positioning component of the device, the pre-positioning can be quickly performed, and then the stability of the fixed connection is enhanced under the action of the butterfly bolt. The operation is simple, convenient and fast. The strip groove arranged on the positioning plate facilitates the adjustment of the clamping position of the patient. The overall assembled structure of the device improves the scope of application. In addition, under the action of the guide groove, the slide groove and the strip groove, the surface liquid can be easily separated during cleaning and disinfection, thereby improving the cleaning and disinfection efficiency.

[0037] The working principle and use process of the utility model are as follows: when in use, the adjacent part of the patient's fracture site is first placed on the top of the bracket 4, and then the automatic inflation pump 7 is started to allow the gas to rush into the interior of the airbag 5 through the trachea. At this time, due to the limitation of the baffle, the airbag 5 can be stably expanded downward to press the top of the adjacent part of the patient's fracture site. At the same time, the patient's comfort and the tightness of the airbag 5 are inquired. The stability of the expansion of the airbag 5 can avoid the situation of secondary injury caused by excessive pressure. After the patient's site is positioned, the automatic inflation pump 7 is turned off, and then the support column 82 is moved to drive the sliding plate 92 to slide back and forth. The forward and backward movement of the sliding plate 92 can sequentially drive the connecting plate 10, the supporting plate 3 and the bracket 4 to move back and forth. When the patient's fracture site moves to a suitable treatment position, it stops moving. Then, by rotating the screw 15 to make the screw 15 threadedly connected to the threaded hole 16, the sliding plate 92, the connecting plate 10, the support column 82 and the top plate 81 can be positioned in turn, thereby avoiding the movement of the bracket 4 in subsequent treatment.

[0038] To sum up: this orthopedic reduction and positioning device, by setting up an airbag 5 and an automatic air pump 7, after the patient places the lower side of the adjacent part of the fracture site on the top of the bracket 4, the automatic air pump 7 is turned on. At this time, the airbag 5 expands downward due to the internal inflation and can limit the upper side of the adjacent part of the patient's fracture site, thereby solving the problem that: when the patient places the fracture site on the arc-shaped support plate, the user needs to drive another arc-shaped support plate to press it down and position it by moving the clamping plate, and the adjustment of the clamping plate by manpower is not accurate enough. If the pressure is too high, it is easy to cause secondary damage to the patient's fracture site. At the same time, the positioning of the fixing rod and the clamping plate by the fixing block and the fixing groove has poor adaptability, and the clamping plate can only be adjusted to the height position corresponding to each fixing groove, which has great limitations in use.
