As further improvement of the utility model, the supraspinal ligament simulation band is by the material with ductility and bending property
Matter is made.
As further improvement of the utility model, the connection member includes the extension positioned at supraspinal ligament simulation strap end portion
Ring.
As further improvement of the utility model, the positioning tube being attached at spinous process is connected on the link, it is described
The section of positioning tube is annular, and link passes through inside positioning tube.
The beneficial effects of the utility model are：The utility model is not changing the base of conventional vertebral pedicle nail rod methods of internal fixation
On plinth, simulated by connect band and rebuild lumbar vertebrae interspinal ligaments, band simulation is simulated by supraspinal ligament and rebuilds supraspinal ligament, makes former quilt
The spinal ligament complex of destruction is continued, and reaches the effect of preventing and treating Adjacent segment degeneration.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of connection member.
Embodiment
Artificial posterior ligament complex as shown in Figure 1, including the connector 1 positioned at middle part, left and right the two of connector 1
End is connected to the connect band 2 for possessing elasticity respectively, and the end of each connect band 2 is connected to what can be located by connecting with nail rod internal fixation system
Positioning element.Nail rod internal fixation system is the resetting means commonly used in corpectomy procedures, also cries fixed system in pedicle screw-rod
System, for example the vertebral body union internal fixation system disclosed in CN 203138656U is may be referred to, it is connected by pedicle screw and longitudinal direction
Take over the baton（Orthopedic rod）Composition, and conventional nail rod internal fixation system typically can all have pedicle screw and Orthopedic rod.Embodiment
In connect band 2 be located by connecting pedicle screw and/or Orthopedic rod by positioning element, broken so as to simulate in surgical procedure
Bad lumbar vertebrae interspinal ligaments.
In addition, the upper termination in connector 1 also has supraspinal ligament to simulate band 3, supraspinal ligament simulation band 3 is provided with can be with spinous process
Connected connection member.Described supraspinal ligament simulation band 3 is connected on the spinous process of human body by connection member, so as to simulate
The supraspinal ligament being destroyed in surgical procedure.
Simulated by connect band 2 and rebuild lumbar vertebrae interspinal ligaments, the simulation of band 3 is simulated by supraspinal ligament and rebuilds supraspinal ligament,
And the ligament of these simulations is fixed up and forms artificial complex, former destroyed spinal ligament complex is continued,
The effect of reaching preventing and treating Adjacent segment degeneration.
In preferred embodiment, positioning element includes that the collar 4 of pedicle screw head can be socketed in and can be placed on strong
The sleeve pipe 5 of shape rod outer wall, the fixed connecting sleeve 5 of the collar 4 and the collar 4 are interconnected with the inside of sleeve pipe 5.In use, Orthopedic rod is worn
After entering in sleeve pipe 5 and sleeve 5 limits the free degree of radial direction, and the head of pedicle screw is limited in the inwall of sleeve pipe 5, by
This realizes the positioning of nail rod internal fixation system and ligament complex.In actual use, connector 1 is located at middle part, by the company at both ends
With nail rod internal fixation system traction action occurs for tape splicing 2, simulates the effect of ligament.
In addition, the top and bottom of each collar 4 are connected to a sleeve pipe 5, it is any so as to which complex is arranged on
Position.Moreover, the axis of the axis of described sleeve pipe 5 and the collar 4 is into an angle for being more than 45 °.Although although angle in Fig. 1
For 90 °, actually the angle is determined according to the mutual alignment between pedicle screw and Orthopedic rod and annexation, vertebra
The angle of pedicle screw and Orthopedic rod is typically no less than 45 °.
Connect band 2 in embodiment is made up of the material with ductility and bending property, so as to which connect band 2 can adapt to not
Same position, nail rod internal fixation system of different shapes, and it is consistent with the property retention of human body ligament.The material example of connect band 2
Such as can be polyester fiber, wherein more commonly used is polyethylene terephthalate.
Supraspinal ligament simulation band 3 equally by with ductility and bending property material be made, and with the material of connect band 2
It is consistent.
The overall material of artificial posterior ligament complex should be polyester, and it can exist in human body for a long time, and
It is not easy to be corroded, not easy damaged.
In preferred embodiment, connection member includes the link 6 positioned at supraspinal ligament simulation band 3 end.The link 6 passes through
It is installed on supraspinous pin, axle or other fixtures, so as to which supraspinal ligament simulation band 3 is connected into spinous process.The shape of link 6
Into can be supraspinal ligament simulation band 3 from end loops around one circle after be fixed into a ring-type.
With reference to figure 2, connection member can also include positioning tube 7 of the section for annular.When being performed the operation, in advance in spinous process 8
A through hole is opened in position, and the insertion of positioning tube 7 is fixed in the through hole.The band 3 of supraspinal ligament simulation afterwards is passed through inside positioning tube 7
Described link 6 is coiled into afterwards, and such supraspinal ligament simulation band 3 directly will not be in contact and rub with sclerotin, ensure that ligament is answered
The fit life-span.
Simply the utility model preferred embodiment described above, it is not formed to scope of protection of the utility model
Limitation.
