Medical rapid reduction internal fixation system for proximal humerus fracture

Abstract

The invention relates to a medical rapid reduction internal fixation system for proximal humerus fracture. The medical rapid reduction internal fixation system comprises a reduction fixation assembly, an angle fixator and an outer sleeve plate assembly; the reduction fixation assembly comprises a fixing disc and a reduction rod, a plurality of fixing needles are arranged on one face of the fixing disc, and a connecting rod is arranged on the other face of the fixing disc; the reduction rod comprises an inner reduction rod and an outer reduction rod which are coaxially arranged; the angle fixator comprises an angle fixing plate and an angle fixing sleeve, the angle fixing plate is fixed to the outer wall of the angle fixing sleeve, a fixing groove is formed in the angle fixing plate, and a sleeve through hole for the connecting rod to be sleeved is formed in the angle fixing sleeve; and the outer sleeve plate assembly comprises an outer sleeve plate body, a sleeve hole position and a plate groove are formed in the outer sleeve plate body, and a humerus head nail hole, a groove hole and a humerus dry nail hole are further formed in the outer sleeve plate body. The problems that reduction needs to be carried out firstly in an existing proximal humerus fracture operation, operation is troublesome, the operation view is affected by temporary fixation, fixation is unstable, and adjustment is difficult when reduction is improper can be effectively solved.

Description

technical field [0001] The invention relates to the field of medical auxiliary devices, in particular to a medical rapid reduction and internal fixation system for proximal humerus fractures. Background technique [0002] Most proximal humerus fractures are osteoporotic fractures, which are a comminuted fracture state, and can be divided into two-part, three-part and four-part fractures. Two-part and three-part fractures are relatively complete, and surgical fixation is relatively easy; however, reduction and fixation of four-part fractures are more difficult. Under the existing technical conditions, the general surgical fixation method for fractures is first open reduction and then internal fixation. Immobilization after reduction can prevent adhesions in the shoulder joint, provide a relatively stable environment for fractures, and speed up the recovery of joint activity. [0003] The two most commonly used methods of internal fixation are plate internal fixation and int...
