Anatomical humerus bridge-type bone fracture plate

Abstract

The invention provides an anatomical humerus bridge-type bone fracture plate and belongs to the field of medical apparatuses. The anatomical humerus bridge-type bone fracture plate comprises a top side surface, a bottom side surface and a group of screw holes, wherein the bottom side surface is used for being in contact with a bone, the screw holes are distributed at two ends of the anatomical humerus bridge-type bone fracture plate, and the bottom side surface of the anatomical humerus bridge-type bone fracture plate is in an anatomical shape of a front outer side surface of a humerus and is used for being adhered to the front outer side surface of the humerus. The anatomical humerus bridge-type bone fracture plate disclosed by the invention is suitable for humerus fracture, is especially used for treating humerus near-end and middle-section bone fracture through an MIPO (Minimally Invasive Plate Osteosynthesis) technology, and can enable the bone fracture to b healed up better.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anatomical humerus bridge bone plate. Background technique [0002] Minimally Invasive Plate Osteosynthesis (MIPO) is a modern fracture internal fixation technique that uses closed fracture reduction techniques and uses non-compressive plate fixation to maintain fracture alignment, minimizing surgical exposure and soft tissue dissection , reducing blood supply damage to tissues such as skin, periosteum, and fracture fragments, can improve the fracture healing rate, and reduce the incidence of complications such as infection or fracture nonunion. [0003] At present, although there are many bone plates that can be used in the MIPO technique for fractures of the proximal and mid-segment of the humerus, due to the uniform distribution of too many screw holes on the bone plate, it not only increases the medical cost, but also often makes clinicians mistakenly place the screw holes o...

AI Technical Summary

Problems solved by technology

[0003] At present, although there are many bone plates that can be used in the MIPO technique for proximal and middle humeral fractures, because there are too many screw holes evenly distributed on the bone plate, it not only increases the medical cost, but also often makes clinicians mistakenly place the screw holes on the fracture end. Complications due to too many screws

Clinically, there is no bone plate specially designed for MIPO technology

In addition, the current bone plate is in the same direction in the sagittal position. Since the radial nerve is close to the bone surface in the middle of the humerus, when the current bone plate is used in MIPO technology, if the pre-bending or poor pre-bending is not used, the radial nerve often becomes damaged. damage
