Abstract

The invention relates to the technical field of medical instruments, in particular to a combined type clamping mechanism for internal fixation of the spine, which comprises a plurality of fixing rods, and a connecting block is arranged between the opposite ends of two adjacent fixing rods. The included angle between the two fixing rods is easily changed through rotation of the movable balls in the movable grooves, then the fixing rods can effectively fix and clamp spines with different bending radians, then the movable balls in the movable grooves are positioned through the first positioning blocks, the included angle between the two fixing rods is fixed, and the spine fixing device is convenient to use. The fixing rods fixed through the included angle are matched with the supporting columns to fix and clamp the spine of a patient, the assembling number of the fixing rods can be selected according to the spine of the patient in different postures, the fixing and clamping device for the spine can be flexibly assembled, and the application limitation of an existing fixing and clamping device in the spine is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined clamping mechanism for spinal internal fixation. Background technique [0002] In today's life, due to the high work pressure of most people, especially those who work in a sitting and standing state for a long time, the incidence of spinal diseases is particularly prominent. Long-term spinal diseases will seriously affect people's health. At the same time, in the current life Among them, when there is a disease in the spine, the surgical treatment is generally the most thorough to solve the spinal disease. However, the surgical treatment will touch a variety of nerves in the spine. Improper handling will cause the failure of the operation. Therefore, it is necessary to use equipment to clamp and correct the spine. Spinal internal fixation devices have been widely used in the clinical treatment of thoracolumbar fractures, spinal tumors, spinal deformity correct...
