Abstract

The invention provides a combined type porous interbody fusion cage and a machining method, and belongs to the technical field of spine internal fixation medical treatment, the combined type porous interbody fusion cage comprises a clamping part, an adjustable part and a limiting mechanism, the clamping part and the adjustable part are each composed of a solid shell and a porous structure, and the clamping part is provided with an instrument clamping column; the clamping part is hinged to the adjustable part, and the rotation angle is limited and fixed through a limiting mechanism; and the invention discloses a processing method of a combined porous interbody fusion cage. The combined porous interbody fusion cage is integrally formed through 3D printing. According to the combined type porous interbody fusion cage and the machining method, the combined type porous interbody fusion cage can be implanted between vertebral bodies of different physiological structures by adjusting the angle, is suitable for TLIF surgical approach, and meanwhile guarantees the structural strength and the bone ingrowth condition, so that the problems that a traditional interbody fusion cage is unitary in matching with the vertebral bodies, and the bone ingrowth and strength are not good enough due to the structure are solved.

Description

technical field [0001] The invention belongs to the technical field of spinal internal fixation, and more specifically relates to a combined porous intervertebral fusion device and a processing method. Background technique [0002] With the changes of modern work and lifestyle and the development of population aging, spinal degenerative diseases have become common diseases in middle-aged and elderly people, including intervertebral disc herniation, lumbar degenerative diseases, spondylolisthesis and other diseases, and their clinical symptoms For neck and back pain. Some patients who fail conservative treatment require surgical treatment to achieve spinal restoration and stability reconstruction. Intervertebral fusion is the classic representative, and it is still the most commonly used spinal implant in surgical treatment. Transforaminal Lumbar Interbody Fusion (TLIF) is a unilateral approach for intervertebral fusion. It is one of the most commonly used surgical methods ...
