Abstract
The utility model discloses a novel memory alloy that wicresoft implanted through centrum pedicle of vertebral arch struts device, include gasbag and the pipe that communicates with the gasbag, the cover has memory alloy to net on the gasbag, memory alloy net forms by the memory alloy spring more than two rings or two rings, pass through welding point welded connection between the adjacent memory alloy spring. The utility model discloses overlap the memory alloy net on the gasbag, in the shrink of 0 DEG C of lower memory alloy net, the present invention has cabinet structure, in being convenient for implant suffer from the vertebra with it through backbone centrum pedicle of vertebral arch, realize minimal access surgery, after in implanting the trouble centrum, the rethread pipe pours into 0 DEG C frozen water in to the gasbag into, the frozen water that leads to the gasbag makes memory alloy net outwardly strutting, the frozen water intensity decision of injection is operated to the degree that struts by art person, and the centrum of sining can resume the height of ideal, avoid excessive strutting, and has a sufficient holding power, keep resumeing the centrum height for a long time, reach the effect that therapeutical centrum is sinkd.
Description
Technical field
This utility model relates to the memorial alloy device for spreading that a kind of novel Wicresoft implants through vertebral body pedicle of vertebral arch, belongs to technical field of medical instruments.
Background technology
Spinal fracture can be caused by many factors.The histological type such as physics responsible (violence traumatic fracture), age physiologic factor (osteoporosis), biological factor (bacterial inflammation, abscess) can be classified as according to the cause of disease.Current treatment-a survey of osteoporotic fracture treatment is divided into expectant treatment and operative treatment, current operative treatment to be mainly open internal fixation treatment, and this therapeutic modality causes surgical wound big, and convalescent period is long, and patient stands more misery；The Kyphon balloons technique occurred in recent years becomes the perfect Minimally Invasive Surgery method of spinal treatments, greatly shortens operation healing stage, and effectively reduces operation risk.But the most also occur in that another kind of risk, the risk that the packing material bone cement used is revealed.Therefore, the therapeutic modality of existing spinal fracture or not ideal enough.
Utility model content
The purpose of this utility model is, it is provided that a kind of simple in construction, memorial alloy device for spreading easy to operate, that implant the novel Wicresoft that body injury is less through vertebral body pedicle of vertebral arch, to overcome deficiency of the prior art.
The technical solution of the utility model: the memorial alloy device for spreading that a kind of novel Wicresoft implants through vertebral body pedicle of vertebral arch, including air bag and the conduit that connects with air bag, air bag is cased with memory-alloy mesh, described memory-alloy mesh is enclosed above memory alloy spring by two circles or two and forms, and is welded to connect by pad between adjacent memory alloy spring.
Described memory alloy spring is to be formed by the continuous print reciprocal bending of waveform steel wire.
Owing to using technique scheme, the utility model has the advantage of: memory-alloy mesh is enclosed within air bag by this utility model, at 0 DEG C, memory-alloy mesh shrinks, its compact structure, it is easy to be passed through the implantation of spinal vertebral pedicle of vertebral arch and suffers from vertebra, realize Minimally Invasive Surgery, after implantation is suffered from vertebra, in air bag, 0 DEG C of frozen water is injected again by conduit, memory-alloy mesh is made outwards to strut by the frozen water of air bag, the frozen water intensity that the degree strutted is operated injection by patient determines, and the vertebral body subsided can be returned to preferable height, avoid excessive strutting, and there is enough support forces, long-term holding, recovers vertebral height, reach to treat the effect of collapse of vertebra.Therefore, memory-alloy mesh of the present utility model selects the memory alloy material with good biocompatibility, such as Ti-Ni marmem, the most safe and nontoxic, nothing rejection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1-air bag, 2-conduit, 3-memory alloy spring, 4-pad.
Detailed description of the invention
In order to make this utility model purpose, technical scheme and advantage clearer, the utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment of the present utility model: the structural representation of the memorial alloy device for spreading that novel Wicresoft implants through vertebral body pedicle of vertebral arch is as shown in Figure 1, including air bag 1 and the conduit 2 that connects with air bag 1, air bag 1 is cased with memory-alloy mesh, described memory-alloy mesh is made up of two circle memory alloy springs 3, is welded to connect by pad 4 between adjacent memory alloy spring 3.Depending on the quantity of memory alloy spring 3 can be according to surgery situation, when needing bigger support force, the quantity of memory alloy spring 3 can be increased.Described memory alloy spring 3 is to be formed by the continuous print reciprocal bending of waveform steel wire, has and preferably shrinks and stretch performance, can not only meet the requirement of the compact structure before implantation, and can also meet the requirement of the support after implantation.
Operation principle of the present utility model: memory-alloy mesh shrinks at 0 DEG C, its compact structure, it is easy to be passed through the implantation of spinal vertebral pedicle of vertebral arch and suffers from vertebra, realize Minimally Invasive Surgery, after implantation is suffered from vertebra, in air bag 1,0 DEG C of frozen water is injected again by conduit 2, memory-alloy mesh is made outwards to strut by the frozen water of air bag 1, the frozen water intensity that the degree strutted is operated injection by patient determines, and the vertebral body subsided can be returned to preferable height, it is to avoid excessive struts, and has enough support forces, long-term holding, recovers vertebral height, reaches to treat the effect of collapse of vertebra.
Claims (2)
