Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to 3D printing anterior stabilization device.
Background technique
Lumbar vertebral disease is common spinal disease type, and the fusion between lumbar vertebrae be treat lumbar vertebral disease method it
One, with the progress of the relevant technologies, more and more people start to receive the treatment of Lumbar Fusion operation.Allograph bone and autologous bone
Transplanting fusion was once the essential therapeutic arsenals of lumbar spinal fusion, but since autologous bone source is limited, increased additional wound, operation is just
The reasons such as phase stability difference, clinical application are limited.And allograph bone same number is limited, and there are the wind such as viral transmission and rejection
Danger, the expense of great number be widely applied it can not in clinic.To reduce operation risk wound, outer fixing belt is reduced
The inconvenience come improves fusion rate of bone graft, while obtaining preferable postoperative Lordosis, and Invasive lumbar fusion device technology starts to become mainstream
Surgical technic.
And conventional polyether ether ketone fusion device is difficult to combine closely with bone tissue, syncretizing effect with merge speed often not
It is very ideal, and the elasticity modulus of titanium alloy material is excessively high, will lead to stress shielding, and centrum is made to be in low-stress state, may lead
Cause osteoporosis.
Utility model content
The purpose of this utility model is that: for existing anterior lumbar interbody fusion device, provide a kind of 3D
Print anterior stabilization device.
To achieve the goals above, the utility model provides a kind of 3D printing anterior stabilization device, Lu Rong before the 3D printing
Clutch is made of solid construction and microcellular structure, and tetrapyamid shape tooth is arranged in upper and lower surface, and microcellular structure is distributed in the preceding road of 3D printing
Inside fusion device, outer wall, upper and lower end face and part tetrapyamid shape tooth, upper and lower end face are arc-shaped, the 3D printing anterior stabilization
There are one 11 ° of angles in device upper and lower end face, and centre is equipped with bone grafting hole.
Preferably, the microcellular structure of the 3D printing anterior stabilization device is distributed in the tooth of fusion device inside and outside wall and upper and lower end face
Between.
Preferably, the 3D printing anterior stabilization equipment material is titanium alloy.
Preferably, the microcellular structure is the micropore of rule distribution, and aperture is 400 ± 200 μm.
Preferably, the microcellular structure porosity is 40 ~ 70%.
Preferably, 3D, which prints anterior stabilization device, has 2 bone grafting holes.
Complicated structure can be processed instead of traditional processing and manufacturing technology by the 3D printing technique of rapid shaping
With shape, and printable shape is without limitation.Pass through microcellular structure approximation bone trabecula manufactured by the technology.Such an arrangement provides
Optimal biomethanics construction and biological environment, and can be according to the fusion for the anatomical form selection different size for not allowing patient
Device.The microcellular structure is capable of providing enough stability, while can also accelerate the fusion and healing of bone.

Description of symbols
1 celled portion 2 of solid section
3 bone grafting hole 4 of tetrapyamid shape tooth.
Specific embodiment
In order to further illustrate the utility model 3D printing anterior stabilization device, the utility model is mentioned below with reference to embodiment
The 3D printing anterior stabilization device of confession is described in detail, but they cannot be interpreted as to the limit to scope of protection of the utility model
It is fixed.
As shown in Figure 1, the utility model 3D printing anterior stabilization device is equipped with round bone grafting hole, the circle bone grafting hole 4 is used
To fill fragment or powdered implantation material.
Before product implantation, matching disc height and soleplate compactness first are removed with die trial, selects the 3D printing of proper height
Anterior stabilization device.
When operation, surgical exposure is carried out first, appears lesion locations, cuts off interverbebral disc, this step depends on patient's experience.
Intervertenral space is gradually strutted using dilator is ascending later, until reaching best intervertenral space.Pass through affiliated threaded hole and counterbore
Fusion device is connected on implanting device, support is located in.Bone grafting fragment is compacted into the bone grafting using bone grafting filling bar later
Hole.Notice that bone grafting must overflow fusion device upper and lower surface.
The 3D printing anterior stabilization device is implanted into, soleplate above and below the phase of tetrapyamid shape flank of tooth face.In side fusion device
When implantation, the dilator of side keeps its softened state and position, after fusion device is in place, rear should away from centrum 2 ~ 4mm of rear wall,
Implanting device is taken out counterclockwise, is removed side dilator, is implanted into the side fusion device in the same way.
The microcellular structure class mechanical characteristic of the 3D printing anterior stabilization device is similar to trabecular bone structure, effectively reduces and answers
Power occlusion effect accelerates bone fusion conducive to the migration and increment of osteocyte, while titanium alloy material provides enough machinery by force
Degree, corrosion resistance and biocompatibility.
3D printing anterior stabilization device and lumbar vertebra are in close contact, and promote its fusion, upper and lower surface tetrapyamid shape tooth can
It effectively prevent 3D printing anterior stabilization device to deviate from, the microcellular structure of fusion device can accelerate bone fusion.
Utility model 3D printing anterior stabilization device structure is simple, can effectively accelerate the fusion of centrum.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
