Embodiment 1

[0030] See Figure 1 to Figure 4 As shown, an improved proximal humeral fixation device 100 of an embodiment is shown, which includes a body portion 10 in a plate structure, and a positioning hole 1 is provided on the body portion 10, and the body portion 10 is positioned through the positioning hole 1 to On the backbone 200 of the humerus; the head 20 extending from the body 10, the head 20 and the body 10 are integrally formed, and the head 20 is correspondingly fixed on the position of the humeral head 201; the fixing part 30 arranged on the head 20 is fixed Part 30 is used to grasp and fix the supraspinatus muscle fulcrum bone fragment 202; some perforations 2 that are located on the body part 10 and the head 20, drive steel nails (not shown) into the body part 10 and the head part 20 from the perforation 2 The head 20 is fixed on the humerus.

[0031] In this embodiment, the body part 10 and the head part 20 can be bent and set at an included angle. The range of the incl...

Embodiment 2

[0043] See Figure 5 As shown, in this embodiment, a fixation device 300 with a bendable, plastic, and universal locking hole structure is proposed to fix the humerus and / or supraspinatus muscle fulcrum bone piece 202, and the positioning holes 301 between two The shapeable steel plate 302 is connected and can be bent and deformed to adapt to the different shapes of the humerus of different patients.

[0044] like Figure 5 As shown, the fixing device 300 includes a plurality of positioning holes 301 and a plurality of steel plates 302 connected to each other to form, one of the positioning holes 301 fixes the supraspinatus fulcrum bone piece 202, and the remaining positioning holes 301 pass through the steel plates 302. The deformation is bent to conform to the shape of the patient's bone, and a steel nail is driven in to fix the fixing device 300 on the humerus. This device can also fix the supraspinatus fulcrum bone piece 202, and can achieve the same technical effect as ...

Abstract

The technical scheme of the invention discloses an improved proximal humerus fixing device and an application method thereof. The improved proximal humerus fixing device comprises a body part which adopts a plate body structure, a head part which extends from the body part, a fixing part located on the head part, and a plurality of penetrating holes which are formed in the body part and the head part in a front-and-rear penetrating manner, wherein a positioning hole which penetrates from front to rear is formed in the body part. According to the technical scheme of the improved proximal humerus fixing device disclosed by the invention, the fixing part which adopts an arc shape and a trident structure is additionally arranged at a head part of an ordinary humerus fracture fixation steel plate, a supraspinatus muscle fulcrum sclerite is seized and fixed by the fixing part,, so that the purpose of fixing the sclerite on the humerus is achieved, and the problem that a conventional fixationsteel plate cannot fix the supraspinatus muscle fulcrum sclerite is solved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an improved proximal humerus fixation device and a use method thereof. Background technique [0002] Proximal humerus fracture is a common clinical disease, accounting for 5% of adult fractures, and is the third place among osteoporotic fragility fractures. According to the degree of fracture, proximal humerus fractures are divided into two-part, three-part, and four-part fractures, and different plate systems are used for different fracture types. Currently, the "proximal humeral locking plate" is commonly used for three-part and four-part fractures; the "greater tuberosity plate" is used to treat simple greater tuberosity fractures. [0003] However, a common problem existing in the existing internal fixation systems is the lack of an effective design to fix the supraspinatus fulcrum bone piece, which leads to the failure of some internal fixation operations. At pr...
