Abstract
The invention discloses a spine fusion fixing device used to implant in an intervertebral space of an intervertebral disk. The device comprises a fusion device (1), and the upper end face and the lower end face of the fusion device (1) are provided with bulges (2). The fusion device (1) is inserted into the intervertebral space of an intervertebral disk through the bulges and is fixedly connected with the intervertebral disk. The fusion device (1) is provided with bone grafting holes (3), and crushed bones of a human body can be put in the bone grafting holes (3) and fused with the intervertebral disk. The spine fusion fixing device has relatively good integration with a spine, and is small in wound, little in bleeding, and fast in recovery after operation. Surgery of implanting the device in a spine is fast and convenient in operation, and time and difficulty of the surgery is shortened, and cost of an implanting surgery is relatively few.
Description
Technical field
The present invention relates to a kind of prosthetic appliance, particularly relate to a kind of spinal fusion fixture of stable lumbar vertebra.
Background technology
Therapeutic Principle about Mechanical back pain is, for have obvious nerve compression symptom through expectant treatment symptom without the situation of alleviation person, then be classified as the indication of operative treatment, operative therapy original adoption spinal canal decompression intervertebral disc marrow nuclear excising art, the outstanding vertebral pulp of disc removal and fibrous annulus tissue is cut through the way of escape, to reach expansion spinal canal decompression, remove the compressing to spinal cord and nerve root.But the excision due to vertebral plate destroys the structure of spinal column, spinal column can be caused to produce new unstable factor and intervertebral space compression is not restored, cause postoperative there is higher relapse rate.
Afterwards, adopted disc removal to add spinal fusion, the basis of spinal canal decompression Nuclectomy was carried out the posterior decompression bone grafting of various mode, as between spinous process, bone-graft fusion, intertransverse process autograft fusion, bone grafting add internal fixation device fusion etc.The object of the fusion type operation of this mode is the intensity of promoting interbody constructs, the unstable spine caused after eliminating vertebrae plate resection, but the height of intervertebral space can not be recovered, and intervertebral activity disappeared after merging, thus cause the regression of adjacent discs to be accelerated.It is also a kind of " shakiness " situation that the activity of single intervertebral activity angle widely reduces, and thus still has many patients to occur that postoperative bone grafting loosens clinically, fractures, absorbs and the phenomenon such as loosening, fracture of internal fixation device.
As depicted in figs. 1 and 2, present traditional fusion device operation needs implantation two pieces of fusion devices, and operation is complicated, difficult, and wound can be caused large and many, hemorrhage more, and patient's post-operative recovery is slow, and syncretizing effect is relatively bad.
Summary of the invention
The object of the present invention is to provide a kind of spinal fusion fixture inserted in the intervertebral space of intervertebral disc.
For achieving the above object, the concrete technical scheme of a kind of spinal fusion fixture of the present invention is:
A kind of spinal fusion fixture, for implanting in the intervertebral space of intervertebral disc, comprise fusion device, the upper surface of fusion device and lower surface are provided with projection, fusion device is fixedly connected with intervertebral disc by protruding insertion in the intervertebral space of intervertebral disc, fusion device is provided with bone grafting hole, the broken bone of human body can be put into bone grafting hole and merge mutually with intervertebral disc.
Further, bone grafting hole is the through hole running through fusion device upper surface and lower surface.
Further, fusion device is provided with two bone grafting holes, two bone grafting holes are symmetrical set along the radial centre lines of fusion device.
Further, fusion device is vertically installed with hole, hole is the through hole running through fusion device side, and hole is rounded, and the broken bone of human body can be put into hole and merge mutually with intervertebral disc.
Further, the end face of fusion device is provided with screw thread, and implantation instrument is connected with fusion device by screw thread, and implantation instrument drives fusion device motion to be inserted in the intervertebral space of intervertebral disc by fusion device.
Further, fusion device is curved.
The advantage of a kind of spinal fusion fixture of the present invention is:
1) better with the amalgamation of spinal column;
2) Post operation wound is little, goes out insufficiency of blood, recovers very fast;
3) implant spinal operation operation faster, convenient, shorten time and the difficulty of operation;
4) expense of implant surgery cost is less.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing fusion device;
Fig. 2 is the side view of existing fusion device;
Fig. 3 is the front view of fusion device of the present invention;
Fig. 4 is the top view of fusion device of the present invention.
Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, further detailed description is done to a kind of spinal fusion fixture of the present invention.
As shown in Figure 3 and Figure 4, it shows for a kind of spinal fusion fixture of the present invention, for implanting in the intervertebral space of intervertebral disc, comprise fusion device 1, the upper surface of fusion device 1 and lower surface are provided with protruding 2, projection 2 is tapered, protruding shape stretches out and diminishes gradually, and top is pointed, and fusion device 1 inserts in the intervertebral space of intervertebral disc by protruding 2 and is fixedly connected with the vertebral plate of intervertebral disc, to prevent fusion device from sliding, avoid Post operation displacement.
Further, fusion device 1 is provided with bone grafting hole 3, the through hole that bone grafting hole 3 is the upper surface and lower surface of running through fusion device 1, the broken bone of human body can be put into bone grafting hole 3 and merge with the spinal column bone photo of intervertebral disc.Wherein, fusion device 1 is provided with two bone grafting holes 3, bone grafting hole is kidney shape, and two bone grafting holes 3 are symmetrical set along the radial centre lines of fusion device.
Further, the two sides, front and back of fusion device 1 are curved, and arc, according to the cross section cambered design of human spine vertebral body, can meet the radian of corpus vertebrae.
Further, the side of fusion device 1 is vertically installed with hole 4, hole 4 is for running through the through hole of fusion device 1 side, and hole 4 is rounded, and the broken bone of human body can be put into hole 4 and merge with the spinal column bone photo of intervertebral disc.In the present invention, fusion device 1 is provided with two circular cavities 4, but is not restricted to only be arranged at two circular cavities.
Further, the end face of fusion device 1 is provided with screw thread 5, implantation instrument is connected with fusion device 1 by screw thread 5, and implantation instrument can drive fusion device 1 to move and to be inserted in intervertebral space by fusion device 1.Preferably, screw thread 5 is arranged on the end of fusion device 1 end face.
