Problems solved by technology

[0004] After the reduction of each fracture block in calcaneal fracture surgery, due to the large amount of cancellous bone compression and the existence of fracture line, it is often necessary to further restore the width. At present, clinicians can only rely on empirical techniques to push or hammer the calcaneus to recover. The width cannot be restored to the normal width accurately, individually, and quantitatively, and the operation may cause soft tissue damage and fracture aggravation during hammering
Due to the lack of suitable and special reduction equipment, it is very difficult to achieve the ideal reduction requirements of calcaneal fracture surgery, which not only often prolongs the operation time, but more importantly, affects the operation effect and is not conducive to the rehabilitation of patients.
This situation has not been fundamentally changed so far, and it has become one of the factors restricting the ideal effect of orthopedic calcaneal fracture surgery, and it is necessary to take measures to solve it

Embodiment Construction

[0017] The present invention is made up of calcaneus splint 1, leading screw 2, tension reducing spring 7.

[0018] As shown in the figure, there are two calcaneus splints 1, the upper part of the calcaneus splint 1 is a rectangular splint surface 3, the splint surfaces 3 of the two calcaneal splints 1 are parallel to each other, and the inner surfaces of the splint surfaces 3 are convex. Protrusion 5, the protrusion 5 conforms to the outer surface of both sides of the calcaneus, exerts more uniform pressure on the calcaneus when clamping the calcaneus, and avoids damage to the soft tissue on the surface of the calcaneus. The lower part of the calcaneus splint 1 is a splint handle 4, and a screw hole is arranged on the splint handle 4.

[0019] Shown in the figure, leading screw 2 passes in the screw hole of two splint handles 4, and the thread of leading screw 2 matches with the screw thread of the screw hole of splint handle, and one end of leading screw 2 has rocker 6. Tur...

Abstract

The invention belongs to the technical field of orthopedic surgical instruments and relates to a width restorer for calcaneal fractures. The width restorer for the calcaneal fractures is used for carrying out width restoration on fractured calcaneus. According to the technical scheme, the width restorer comprises calcaneus splints and a lead screw. The plate faces of the two calcaneus splints are parallel and opposite. A splint handle is arranged on the lower portion of each calcaneus splint. The lead screw is arranged in threaded holes of the two calcaneus splints in a penetration mode. One end of the lead screw is provided with a rocker handle. The calcaneus splints are clamped on the two sides of the calcaneus, and a person can rotate the lead screw, softly apply pressure on the two sides of the calcaneus and enable a bony defect gap of a calcaneus body to disappear so that the original width of the calcaneus can be restored and the satisfactory effect can be achieved. The width restorer for the calcaneal fractures is scientific and reasonable in structure, convenient to use, good in restoration effect and capable of accurately and quantificationally restore the normal width of the calcaneus in a personalized mode, preventing soft tissue injury and facture exacerbation, shortening the surgical time and ensuring that an operation has an ideal effect, solves the long-term unsolved problems that the restoration difficulty of the calcaneus is great, the surgical time is long and the radiation dosage is large, and is suitable for being applied and popularized in primary hospitals and large hospitals.

Description

technical field [0001] The invention relates to an auxiliary appliance for width reduction of a fractured calcaneus in orthopedic calcaneal fracture reduction and internal fixation operation, and belongs to the technical field of orthopedic surgical appliances. Background technique [0002] Calcaneal fracture is a common injury in trauma orthopedics. Falling injury is the most common. The patients are mainly young and middle-aged, and most of them are caused by work-related accidents in the construction industry. 60%-75% of calcaneal fractures are displaced intra-articular fractures, and open reduction and internal fixation have become the first choice for most displaced calcaneal fractures. [0003] The typical joint of the calcaneus is composed of the primary fracture line and the secondary fracture line. The talus and the talus-bearing bone fragments are usually constant, and the other fracture fragments are displaced and rotated to varying degrees. The primary fracture ...
