A multi-functional spinal simple variable-angle internal fixator

Abstract

The invention discloses a multifunctional simple variable-angle spinal internal fixator, which comprises a fixing bayonet, a connecting rod, a connector, a spinal fixator bearing column, a spinal lower fixator and a spinal fixing correction connecting rod, wherein the spinal fixator bearing column is arranged in the inner cavity of a bearing rod movable cavity; the spinal lower fixator is arranged on the outer wall of the spinal fixator bearing column; and the spinal fixing correction connecting rod is arranged on the inner wall of a bearing hole. According to the multifunctional simple variable-angle spinal internal fixator, through the perfect combination of variable-angle spinal internal fixation and spinal correction, the fixator can be regulated by virtue of a transverse connecting rod through a spacing regulator, so that the spinal bone of a human body is effectively fixed by virtue of the variable-angle spinal internal fixator; meanwhile, since the entire simple variable-angle spinal internal fixator is provided with a plurality of movable shafts and movable rings, the entire fixing instrument is more flexible to operate; and meanwhile, the fixator is simple in structure, and is capable of meeting demands on spinal fixing, spinal correction and the like.

Description

Technical field [0001] The invention relates to the field of medical technology, in particular to a multifunctional spine simple variable-angle internal fixator. Background technique [0002] At present, there are many kinds of similar fixation devices used in the treatment of spinal diseases or trauma in the domestic market. However, due to the complexity of the patient’s disease, there are more or less unreasonable or defects in the structure design of this kind of fixator. In order to expand the scope of clinical application, some internal fixation devices for spine deflection make the structure of the fixator more complicated, and the assembly is extremely slow in clinical use. At the same time, the existing spine deflection internal fixator is simple in structure and easy to use. It is more convenient, but the spine variable angle internal fixator can only fix the spine alone, which is convenient for doctors to perform surgical operations. For some patients with severe spina...

Problems solved by technology

[0002] At present, there are many kinds of similar fixation devices for the treatment of spinal diseases or trauma that are produced and marketed in China. However, due to the complexity of the patient's disease, there are more or less unreasonable or flaws in the structural design of this type of fixator. In order to expand the scope of clinical application, some spinal variable-angle internal fixation devices make the structure of the fixator more complicated, and the assembly is extremely slow in clinical use. It is more convenient, but the spinal variable-angle internal fixator can only fix the spine alone, which is convenient for doctors to perform operations. For some patients with severe spinal deformation, not only the spinal variable-angle internal fixator is needed, but also Installing a spine correction frame not only hinders the doctor from treating the patient, but also has a great impact on the patient's spine
