Background technology
Waist interbody fusion is one of method for treating spinal disease, and annual more and more crowds receive interbody fusion Treatment.Interbody fusion includes autologous bone transplanting fusion and allogenic bone transplantation fusion, due to autologous bone limited source, increases and supplies Area's wound cannot provide the shortcomings of timely mechanically stable so that the clinical practice of interbody fusion is restricted, and different at present Body bone collection limited amount, affects allograph bone in wide clinical application, so allograph bone utilization rate can be improved again by designing The subject solved close to physiologico-anatomic product into needs.
Patent 201610422291.2 discloses a kind of spinal fusion device.It integrally has the three-dimensional porous structure communicated, By wire by weaving, being sintered.The spinal fusion device is overall structure, it is impossible to be provided timely mechanically stable.
Patent 201110409683.2 discloses a kind of spinal fusion device of lined with reinforced ribs, including agent structure and is embedded in Metal inner lining reinforced structure body therein, the agent structure are the tubular structure there are two hollow hole, and the metal inner lining adds Muscle structure includes the cylinder of two internal thread structures that metal connecting bridge is connected with by the metal connecting bridge, the metal Connecting bridge is in the tube wall of the tubular structure.Horizontal section imitates spinal anatomy, is carried by the form of lined with reinforced ribs High spinal fusion device integral strength, toughness increase the range of choice of novel biomaterial.It is main logical during implant surgery Cross metal liner muscle structural bearing main part enter it is internal, can to avoid spinal fusion device in surgical procedure, probably due to Severe mechanical environment damages, and seriously affects successful surgery.But the spinal fusion device is overall structure, it is impossible to be provided timely It is mechanically stable, allograph bone utilization rate is low.
Invention content
For the above-mentioned technical problem in the relevant technologies, the present invention proposes a kind of spliced homogeneous allogenic bone fusion device, both The utilization rate of allograph bone can be improved, and can be preferably close to physiological anatomic architecture.
To realize the above-mentioned technical purpose, the technical proposal of the invention is realized in this way：
A kind of spliced homogeneous allogenic bone fusion device is made of left fusion body 1, right fusion body 2 and pin 3, described It is left fusion body with it is right fusion body can mutually be blocked by mechanical concaveconvex structure and, the pin 3 is arranged on spliced allogeneic The trailer card of bone fusion device and position prevent left fusion body and right fusion body phase separation；The spliced allogeneic The left fusion body of bone fusion device and right fusion body may be designed as symmetrical structure, mutually be glued left and right two parts by medical adhesive It closes.
1 tail portion of the left fusion body sets the first dovetail shaped protrusion 4, and head sets the first dovetail groove 5,
The right fusion body tail portion setting and the second dovetail groove 6 of the first dovetail shaped protrusions, the right fusion Body head sets the second dovetail shaped protrusion 7 to match with the first dovetail groove.
First through hole 8 is set on the left fusion body；
The second through-hole 9 is set on the right fusion body；
The pin connects together left fusion body with right fusion body with the second through-hole through first through hole；
The spliced homogeneous allogenic bone fusion device is provided with pawl shape spinous process 10 in both sides up and down, convenient for holding centrum, Centre setting bone grafting hole 11, implantable bone bits, conducive to the generation of bone.The spliced homogeneous allogenic bone fusion device head petition Warhead shape 12, convenient for implantation.
The spliced homogeneous allogenic bone fusion device pawl shape spinous process face is set in radian.
The bone grafting hole is in ellipticity.
Slot 13 is symmetrical arranged on the outside of the spliced homogeneous allogenic bone fusion device, tail portion is threaded hole 14, above-mentioned to set It puts and is captured convenient for instrument.
Beneficial effects of the present invention：Due to allograph bone limited source, and its is expensive, so the abundant use of allograph bone Seem critically important, it is not only stringent to the shape performance requirement of allograph bone directly to process whole Invasive lumbar fusion device, Er Qiehui The waste of allograph bone is significantly caused, and the spliced homogeneous allogenic bone fusion device in the present invention can be spliced, it is right The limitation of allograph bone shape is small, can improve the utilization rate of allograph bone to greatest extent.
