Problems solved by technology

[0003] However, there are some shortcomings in the bridging combined internal fixation system for bone lengthening on the market at present. The traditional internal fixation system is not flexible enough in the process of fixing the patient's bone, which limits the convenience of medical personnel's operation. , it does not have a flexible and convenient extension function, which limits the extension performance of the internal fixation system

Abstract

The invention relates to the technical field of bone extension, discloses a bridging combined internal fixation system for bone extension. The invention aims to improve the convenient installation and use performance of the bridging combined internal fixation system for bone extension. The bridging combined internal fixation system for bone extension is composed of a supporting and positioning mechanism and a hoop positioning mechanism, wherein the supporting and positioning mechanism is clamped with the hoop positioning mechanism through an extension supporting rod. Through the combination of the supporting and positioning mechanism and the hoop positioning mechanism, the internal fixation system has flexible and convenient assembly performance, medical personnel can conveniently assemble the internal fixation system on a skeleton of a patient, the operation convenience of the medical personnel can be improved, and meanwhile, the pain of the patient can be reduced; and in the using process of the system, through clamping connection of an extension assembly in the hoop positioning mechanism and an extension supporting rod in the supporting and positioning machine, the supporting length of the internal fixation system can be adjusted, and then the flexible usability of the internal fixation system is improved.

Description

technical field [0001] The invention relates to the technical field of bone lengthening, in particular to a bridging combined internal fixation system for bone lengthening. Background technique [0002] Bone elongation, that is, distraction osteogenesis, is to cut the bone, retain the soft tissue and blood supply, fix the two ends with a special traction device, apply the tension stress law to gradually apply tension to slowly pull the bone segment, continuously stimulate the body tissue, and stimulate the bone segment. The regenerative potential of human tissue enables the formation of new bone in the osteotomy gap and achieves the purpose of bone regeneration. It is suitable for: the elderly with trauma, bone infection, congenital bone shortening, tumor and symptoms ranging from lower limbs, because Tumor and congenital reasons, the anterior wall and lower limbs are unequal in length and unbalanced, which will cause deformity and insufficiency of the joints near the phosph...
