AI Technical Summary

Technical Problem

Existing calcaneal fracture reduction devices require experienced doctors to operate, which is labor-intensive and the reduction accuracy is difficult to guarantee. In addition, intelligent devices are expensive and not universally applicable.

Method used

A repositioning device comprising a leg support, an extension block, an adjustment rod, and a traction pin was designed. It achieves three-dimensional repositioning of the calcaneus through detachable and threaded connections. The limiting structure of the fixing screw and the sliding sleeve simplifies the operation and reduces reliance on the doctor's experience.

Benefits of technology

It achieves high-precision calcaneal fracture reduction without requiring extensive clinical experience, reducing labor intensity and improving operational efficiency, and is suitable for most doctors.

Abstract

The utility model relates to the technical field of medical instruments, and discloses a calcaneal fracture reduction device which comprises a leg support, a first extension block and a second extension block, the first extension block and the second extension block are arranged at one end of the leg support, and the first extension block and the second extension block are detachably connected with the leg support through connecting pieces. An upward moving adjusting rod is detachably installed on the second extending block, a connecting block and a short-shrinkage connecting rod are detachably connected to the extending rod, an outward moving adjusting rod is arranged on the connecting block in a threaded and penetrating mode, and an outward moving base block is rotationally connected to the lower end of the outward moving adjusting rod. The sliding sleeve can move along the axis direction of the traction needle under the extrusion of external force, and is clamped and fixed with the bayonet; and a limiting bulge is arranged on the traction needle and is used for limiting the sliding sleeve when the sliding sleeve is clamped with the bayonet. The calcaneus reduction device can effectively facilitate operation of a doctor, and meanwhile the doctor can manually and locally adjust the calcaneus reduction device conveniently in the calcaneus reduction process.
