Device for exposure of comminuted calcaneal fracture during operation

Abstract

The invention discloses an intraoperative device for exposure of a comminuted calcaneal fracture. The device comprises a base, wherein a frame body is fixed on the base; a longitudinally arranged bar is arranged on the frame body; the bar comprises a group of cylindrical blocks which are longitudinally distributed and are provided with through holes; rolling bearings are arranged at the upper end and the lower end of each cylindrical block; outer rings of all rolling bearings are fixed to the cylindrical blocks; inserting blocks are fixed on inner rings of the cylindrical blocks; column tubes are arranged on the inserting blocks; the inserting blocks all are fixed in the corresponding through holes of the column tubes; a fixed block is fixed on the outer contour surface of each column tube; each fixed block is in threaded connection with a bolt; guide rods are fixed on the contour surfaces of all cylindrical blocks; a channel I communicating with the through hole of the corresponding cylindrical block is formed in each guide rod; the through holes of the cylindrical blocks communicate with the through holes of the column tubes; a channel II is formed in a connecting rod at the topmost end; a guide ring frame is fixed on the connecting rod at the topmost end; the channels I, the channel II and the guide ring frame are provided with pulling ropes; and a latch needle is fixed at the outer end of each pulling rope. The intraoperative device is ingenious and reasonable in structure and worthy of popularization and application.

Description

technical field [0001] The invention relates to a medical tool, in particular to a device for exposing the comminuted fracture of the calcaneus during operation. Background technique [0002] The calcaneus is the largest tarsal bone, and it plays an important role in the body's weight-bearing and walking. When the calcaneus is under excessive force, it will cause a comminuted fracture of the calcaneus. When current doctors treat the calcaneus comminuted area, they first treat the foot Cut the skin and soft tissue of the lateral part of the calcaneus, insert a Kirschner wire on the exposed lateral surface of the calcaneus, bend the Kirschner wire, and use the bent Kirschner wire to press the lifted lateral skin and soft tissue of the calcaneus ( Such as Figure 10 As shown), so that the crushed calcaneus is exposed to facilitate the operation. Due to the long operation time, the Kirschner wire is used to press the opened outer skin and soft tissue of the calcaneus for a long ...

Problems solved by technology

[0002] The calcaneus is the largest tarsal bone, and it plays an important role in the body's weight-bearing and walking. When the calcaneus is under excessive force, it will cause a comminuted fracture of the calcaneus. When current doctors treat the calcaneus comminuted area, they first treat the foot Cut the skin and soft tissue of the lateral part of the calcaneus, insert a Kirschner wire on the exposed lateral surface of the calcaneus, bend the Kirschner wire, and use the bent Kirschner wire to press the lifted lateral skin and soft tissue of the calcaneus ( like Figure 10 As shown), so that the crushed calcaneus is exposed to facilitate the operation. Due to the long operation time, the Kirschner wire is used to press the opened outer skin and soft tissue of the calcaneus for a long time, which may easily cause the pressed skin and soft tissue to be damaged after the operation. Partial necrosis occurs during the recovery process, and even complications such as infection and steel plate exposure occur in the necrotic area, resulting in operation failure, increased medical expenses and hidden dangers of doctor-patient disputes
