Description

Upper limb fracture reduction tractor

Technical Field

The utility model relates to a medical appliance, which belongs to the field of clinical medical orthopedic surgery, in particular to an upper limb fracture reduction tractor.

Background

Fracture of upper limb is a common injury in orthopedics and traumatology in clinic, and the treatment method is generally divided into two types of operation treatment and conservative treatment. The operation treatment mostly adopts the incision reduction steel plate screw internal fixation and the external fixation, and after the fracture of a patient is healed, the internal fixation is usually removed by a secondary operation. The treatment method has high risk, great pain, great cost and long treatment period for patients, and often causes the pain of secondary operation. The conservative treatment is usually to reduce plaster or splint external fixation by anesthesia downlink fracture technique, to make the alignment of two ends of fracture reach the conservative treatment standard, to periodically check, to adjust the tightness of the splint or plaster fixation, to remove the plaster or splint and other external fixation devices for 4-6 weeks, to perform functional exercise until the fracture is completely healed. The eight traditional Chinese medical methods of bone setting, namely heart touch, stretching and traction, rotary stretching and bending, pressing and end squeezing, swinging and touching, bone separation by squeezing and pinching, bending and rotating, massaging and massaging, are usually adopted in the reduction of bone fracture manipulation, and usually at least two persons, namely an operator (A doctor) and an assistant (B doctor), are required for the operation, and sometimes more assistants are required. Taking the reduction of distal radius fracture as an example, during the reduction of the fracture, the physician (A) and the assistant (B) respectively fix the wrist and the proximal elbow of the forearm of the affected limb, continuously pull, sequentially correct the deformity of the affected limb such as shortening, angulation and lateral displacement by using the eight methods of bone setting such as "pulling, stretching, rotating, bending, pressing, lifting, touching, pinching and splitting" and the like, and after the reduction is satisfied, the assistant must continuously maintain the traction to prevent the displacement, and usually needs at least one other assistant (C) to fix the prepared splint by binding the splint and the binding belt after the lining. The manual reduction usually depends on the strength of the arms of the treating staff to maintain a certain stretching traction force, and the great strength is usually needed to resist the shortening and the malformation of the fracture broken ends caused by muscle contraction.
