External fixation device for bones

Abstract

The invention provides an external fixation device for bones. The external fixation device comprises a proximal scaffold, a distal scaffold and a fixation regulating structure, wherein the proximal scaffold is arranged on a proximal bone at the bone fracture position in a sleeving manner; the distal scaffold is arranged on a distal bone at the bone fracture position in a sleeving manner, and is used for clamping a distal steel needle passing through the distal scaffold, and the distal scaffold is connected with the proximal scaffold; and the fixation regulating structure is arranged on the distal scaffold, and is used for being connected with the distal steel needle so as to regulate the position of the distal steel needle, so that the distal steel needle can be nailed into the distal bone. When the distal steel needle is nailed into the distal bone, the fixation regulating structure can finely regulate the position of the distal steel needle, so that the distal steel needle can be nailed into the distal bone from a preset position at another angle or position, and thus, the problem that a steel nail deviates from the preset position due to the fact that a medical worker manually regulates the position of the steel nail at present is effectively solved, so that the distal steel needle can be accurately nailed into the preset position of the distal bone to ensure the restorationeffect of the bones.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bone external fixation device. Background technique [0002] For the current external fixation brace for bone fixation, it is composed of multiple parts such as ring parts, connecting rods, and steel nail fixing parts. The process of use is to first combine the parts and then connect them to the steel nails on the bone. , and then slowly adjust the bones to the appropriate position. The adjustment process needs to rely on the doctor's experience to adjust. Usually steel nails need to be nailed into the bone according to the predetermined position to ensure accurate bone reduction. If there is bone slag in the predetermined position and the steel nail cannot be nailed in, the medical personnel need to manually adjust the position of the steel nail. However, during the adjustment process, the position of the steel nail will deviate from the predetermined position, w...

AI Technical Summary

Problems solved by technology

[0003] Based on this, it is necessary to provide an external bone fixation device that can facilitate the adjustment of the distal steel pin for the current situation where the steel pin deviates from the predetermined position due to the manual adjustment of the steel pin position by the medical staff.
