Description
Technical field
The invention belongs to technical field of medical instruments, especially relate to a kind of memorial alloy making Expansible centrum support frame
Pipe.
Background technology
In research in advance, we devise serial memorization alloy corpus vertebrae expansible support: nickel titanium temperature memorial alloy
Vertebral compression fracture orthopedic repositor and device (ZL 200610024715.6), corpus vertebrae expansible orthopedic positor (ZL
200820006206.5), Expansible centrum support frame (ZL 201020106368.3), implant the expansible multiple of spinal lesion vertebral body
Position support (ZL 200720067399.0).
In above-mentioned Patent design, with pipe and plate, support done design and related experiment.But the most still
Needing the support problem of different designs under the conditions of there is different sclerotin, e.g., between twenty and fifty bone regeneration capability is good, and implanting support needs
Stent-expansion under the conditions of between twenty and fifty vertebral body sclerotin, now, requires height to the biomechanical strength of support.And sclerotin is dredged
The gerontal patient of pine state, requires height, now, it is only necessary to support can produce the cavity of maximum, it is simple to aggregate to vertebral body internal cavity
The filling of material.For most of middle-young patients, anterior margin of vertebral body is subsided, and needs to increase leading edge and subsides the bracing force at position, again
Will fill bone material through tail end, support irrigates asking of being difficult to simultaneously to realize to the strength of the anterior vertebral and tail end material
Topic.The support tail pipe that the tubing of common tube walls parallel is developed is narrow, and it is difficult that packing material easily occurs filling difficulty, even practical operation
To realize.And the support tail end of sheet material development exists connection problem, the leakage being likely to result in material filling is not held in the mouth with operational
Connect.And in actual vertebral fracture pathological changes, anterior margin of vertebral body partial collapse becomes apparent from and seriously, this just requires designed support
The strength of forward part to be increased.How to solve this problem, become the bottleneck of support Design application.Now, the design of support needs
Mentality of designing to be changed.
For designing and producing the memory alloy pipes of support, need to consider the biomechanics state of various sclerotin state bone, i.e.
Support (between twenty and fifty vertebral fracture) and only expansion vertebral body cavity (under senile osteoporosis state) of pure mechanical support function
Two extremities.And for need under most of states to take into account more support fracture is subsided vertebral body support with to expansion cavity
The perfusion of filling material of bone is filled.
The support that early stage is developed, mechanical strength is about 75N (during compression displacement 2mm) in 0.8mm tubing；Initial reality
Test about the 40N (during compression displacement 2mm) of 0.75mm plate support.
Along with research is goed deep into, the actual application support strength of support is connected bone material with expansion cavity and tail end and injects pipe not
Can the defect of effective connection problem also be completely exposed, it is necessary to original design is reformed.
Summary of the invention
The present invention seeks to: provide one to utilize the original memory performance of memorial alloy, in vertebral body, form good cavity,
Facilitate implementation Wicresoft, disposable surgical, and vertebral body is had to the making Expansible centrum support frame of mechanical support and reset response
Memory alloy pipes.
The technical scheme is that a kind of memory alloy pipes making Expansible centrum support frame, nickel titanium temperature remember
Alloy is integrated into, and this memory alloy pipes includes cylindrical outer wall pipe, and be located within described cylindrical outer wall pipe interior
Tube chamber；The two ends outlet in said inner tube chamber lays respectively in the circular end face of described cylindrical outer tube wall head end, tail end；This inner tube
Chamber can be made by cutting, mold, 3D printing technique or technique for grinding.The change of internal stent structure, manufactures different structure power
The support of amount is filled with vertebral body structure, vertebral fracture rule and tail end material and is injected packing material connection problem and obtains disposably
Solving, under frozen water state, the support shaping of this memory alloy pipes development is tubulose, after implanting vertebral body, under body temperature
Tubulose can complex be support voluntarily；According to clinical all ages and classes patient's vertebral body sclerotin regeneration capacity and mechanical strength, adjust inner tube
Chamber can get the support of different wall.
Support end section tube wall is the most thinning, can produce micro-elasticity function, this to the growth healing of bone and support from
Body safety (avoiding leaflet to rupture excessive with support hardness to the soleplate effect of rushing to summit) is significant；Tail end caliber can increase
Add Aided Design, inject, with pouring material, the converged functionality that pipe can reach good, it is simple to injecting of material.

≥0.05mm。
As preferred technical scheme, said inner tube chamber is tube chamber in taper, in described taper the aperture at tube chamber two ends and
Macropore lays respectively in the circular end face of described cylindrical outer tube wall head end, tail end, at design and the bracing force considering support
During with the micro-elasticity function of tail end perfusion channel and support, can be by the whole support of Slope angle adjustment of tube chamber in taper
Design, uses distraction reduction, recovery that the support that tube chamber makes in taper has except intraluminal stent in plain cylindrical form simultaneously
Fractured vertebral body geometric shape with produce outside cavity function, the anterior vertebral position is had preferably by the higher support force of its head end
Support, the tail end of expansion be more convenient for fill bone material, improve fractured vertebral body healing efficiency, solve support need in vertebral body before
End increases support force, and tail end increases caliber, it is simple to the problem that material is filled, it is achieved the operability of clinical practice is with the most excellent
Change operation technique.
As preferred technical scheme, in described taper, the aperture of tube chamber is as the convergence hole of puncture guide pin, and its aperture can
It is processed as circle, ellipse, triangle, cross or female thread structure, as implanting entrance hole.
As preferred technical scheme, described cylindrical outer wall pipe is provided with some spaced leaflets and cuts
Seam, and each leaflet cuts the two ends of seam and converge at the head end of described cylindrical outer wall pipe, tail end respectively, the shape of leaflet and
Number can adjust relatively according to design needs.
As preferred technical scheme, it is 3-10 that described leaflet cuts the quantity of seam, and optimal number is 6, and will circle
Cylindrical outer wall pipes etc. point are arranged.
As preferred technical scheme, the tail end of described cylindrical outer tube wall is provided with short tube convergence part, holds in the mouth at described short tube
The portion of connecing is provided with one or several and the bone material injector top lofty draw-in groove matched of connection tube or thread groove, it is ensured that
Frame difficult drop-off, also allows for the intrusion pipe infusion to packing material.
The invention have the advantage that
