Abstract

The utility model relates to the field of medical devices, in particular to a spine interbody fusion cage with an asymmetric cavity, which comprises an interbody fusion cage body, a cavity, outer side walls and an inner side wall, wherein the interbody fusion cage body is a cuboid in shape, and the head is streamlined; the interbody fusion cage body is the asymmetric cavity; the thickness of the outer side walls is smaller than that of the inner side wall; and the two outer side walls are arranged at the same side of the interbody fusion cage body. The spine interbody fusion cage is used for posterior lumbar surgery. Due to the streamlined head of the interbody fusion cage body, the resistance is reduced, the implantation operation is easy, and the wound of the patient is small. Owing to the asymmetric cavity, thinner outer side walls and thicker inner side wall, the contact area with the vertebral end plate is increased, thereby being beneficial to the bone grafting fusion and reducing the sinking and displacement problems of the interbody fusion cage.

Description

Asymmetric cavity spinal column Invasive lumbar fusion device
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of asymmetric cavity spinal column Invasive lumbar fusion device.
Background technology
The spinal column Invasive lumbar fusion device is one of Main Means for the treatment of spinal column intervertebral disc disorder.Use the spinal column Invasive lumbar fusion device except the height that can keep intervertebral space, recover the support of spinal column front pillar, center pillar, increase the capacity of intervertebral foramina, solve the compressing of nerve root.The design of the cavity of present spinal column Invasive lumbar fusion device both domestic and external all is symmetric design, and the thickness of interior lateral wall is identical, has reduced the contact area with terminal plate of vertebral body, be unfavorable for bone-graft fusion, has increased that Invasive lumbar fusion device subsides and the generation of the problem that is shifted.
Summary of the invention
The purpose of this utility model provides a kind of asymmetric cavity spinal column Invasive lumbar fusion device that is conducive to bone-graft fusion.The technical solution adopted in the utility model is, asymmetric cavity spinal column Invasive lumbar fusion device comprises Invasive lumbar fusion device cage body, cavity, lateral wall and medial wall, and Invasive lumbar fusion device cage body profile is cuboid, and head is streamlined; Invasive lumbar fusion device cage body is asymmetric cavity, and the wall thickness of the lateral wall of Invasive lumbar fusion device cage body is less than the wall thickness of medial wall, and two lateral walls place Invasive lumbar fusion device cage bulk phase the same side.
The wall thickness of described lateral wall is less than the wall thickness 0.5～4mm of medial wall.
The advantage that the utlity model has and beneficial effect are: this utility model has increased the contact area with terminal plate of vertebral body, is beneficial to bone-graft fusion, has reduced that Invasive lumbar fusion device subsides and the generation of the problem that is shifted.The problem that exists in order to solve background technology, the spinal column Invasive lumbar fusion device comprises having the approximate cuboid of profile, header stream Alignment Design Invasive lumbar fusion device cage body, Invasive lumbar fusion device cage body is asymmetrical cavity design, the medial wall that the lateral wall that thickness is less and thickness are larger.The header stream Alignment Design of Invasive lumbar fusion device cage body reduces resistance, be easy to the Operation operation, reduce patient's wound, the lateral wall that asymmetrical cavity designs, thickness is less and the larger medial wall of thickness have increased the contact area with terminal plate of vertebral body, be beneficial to bone-graft fusion, reduced that Invasive lumbar fusion device subsides and the generation of the problem that is shifted.

Fig. 4 is right view of the present utility model.
The specific embodiment
Referring to accompanying drawing, the spinal column Invasive lumbar fusion device comprises having the approximate cuboid of profile, header stream Alignment Design Invasive lumbar fusion device cage body 1, and Invasive lumbar fusion device cage body 1 is asymmetrical cavity 2, the lateral wall 3 that thickness is less, 5 and the larger medial wall 4,6 of thickness.Two lateral walls place Invasive lumbar fusion device cage body 1 phase the same side. Lateral wall 3,5 wall thickness are less than medial wall 4, wall thickness 0.5～4mm of 6.Two symmetrical implant into body intervertebrals of Invasive lumbar fusion device, the medial wall is positioned at the inboard of transverse section, and the lateral wall is positioned at the outside of transverse section.
The header stream Alignment Design of Invasive lumbar fusion device cage body 1 reduces resistance, be easy to the Operation operation, reduce patient's wound, the medial wall 4 that asymmetrical cavity 2 and thickness are larger, 6 and the less lateral wall 3,5 of thickness increased contact area with terminal plate of vertebral body, be beneficial to bone-graft fusion, reduced that Invasive lumbar fusion device subsides and the generation of the problem that is shifted.
