Abstract
The utility model relates to a centrum humidifier of treatment centrum compressibility fracture, the body of centrum humidifier for straight prism or cylinder, the body have run through around the centre bore of terminal surface, the centre bore of body has the internal thread, the side of body has the side opening that leads to the centre bore, the side of body is equipped with external screw thread or pawl, the side of body is close to the sunken clamping face that forms of rear end face department, the different development mark of tangible form is established to the terminal surface around the body. Its advantage shows: the mechanics parameters such as elastic modulus of artifical aggregate material are close the sclerotin, incidence that reducible adjacent centrum fractures again, because the centrum humidifier does not have the mobility, so position, form, volume when implanting are comparatively controllable, recovering centrum form that can be better, the centrum humidifier is solid -state implant, does not have pulmonary embolism, bone cement and the complication such as reveals, the back is implanted to artifical aggregate material, and can carry out good integration long term with the sclerotin, avoids the pain that the interface fractures a little and lead to.
Description
Technical field
The utility model is related to orthopedic medical device technical field, is the vertebra for treating compression fracture of vertabral body specifically
Body booster.
Background technology
With the development of aging society, annual new osteoporosis centrum compression fracture patient nearly 1,810,000.According to system
Meter, there are about 16% postmenopausal women and 20% more than 70 years old crowd occurred vertebral fracture.Vertebral compression fracture is faced
Bed treatment most common method is vertebral body plastic operation, the micro-wound percutaneous vertebral body plastic operation (percutaneous for carrying out in recent years
Vertebroplasty, PVP) and percutaneous kyphoplasty (percutaneous kyphoplasty, PKP) due to wound
Little, energy rapid pain relief, is the new effective treatment method of Osteoporotic Vertebral Compression Fractures, obtains satisfied clinical knot
Really, the quality of life of patient is significantly improved.
Polymethyl methacrylate (polymethyl methacrylic, PMMA) bone cement is wide in PKP and PVP operations
The general implantation material for using, it has the advantages that mechanical strength height, curing rate are fast, but clinician has found in application process
The material there is also notable defect：The elastic modelling quantity of PMMA is 4～40 times of vertebral cancellous bone, and too high elastic modelling quantity causes into
The hardness of shape centrum excessively increases, and produces stress concentration, and then causes neighbouring centrum compression fracture again；PMMA lacks biological living
Property, it is impossible to degraded absorbs, be present in centrum in foreign matter form for a long time etc..
The utility model is using centrum booster made by a kind of new monoblock artificial bone to osteoporosis centrum pressure
Contracting fracture is treated, and it is relative to the advantage of PKP and PVP：1st, the mechanics parameter such as elastic modelling quantity of artificial bone
Close sclerotin, can reduce the incidence that adjacent vertebral is fractured again；2nd, because centrum booster is with mobility, therefore during implantation
Position, form, volume are more controllable, can preferably recover centrum form；3rd, centrum booster is solid implant, there is no lung
The complication such as embolism, bone cement leakage；4th, after artificial bone implantation, long term can carry out good fusion with sclerotin, it is to avoid boundary
Pain caused by the micro fractures of face.
Traditional bone cement implantation punctures implantation using pedicle, also has researcher and adopts for implantation " centrum pillar block "
Pedicle approach, although pedicle approach can avoid damage to bony structure and ligament, reduces overall to postoperative backbone biological
The impact of mechanical stability, but make the implants of the close 10mm of diameter largely to destroy vertebra through pedicle of vertebral arch implantation centrum
The structure of nut, and cause difficulty to implantation process.The utility model is using the Jing transverse process approach and Jing greater psoas muscle approaches innovated
Two kinds of operative approaches, can reduce the destruction to pedicle of vertebral arch, the more conducively placement of implants.Two kinds of approaches are as follows：
A：Jing erector spinae spatium intermusculares remove transverse process approach
Patient is placed in prone position, and in the way of escape one side Jing erector spinae spatium intermusculare approaches transverse process is arrived at, and gun rongeur removes horizontal
It is prominent, periosteum and attachment segmental vessels thereon and grey ramus communicans albus are peeled off in centrum side, in pedicle of vertebral arch height, 1/3 after centrum
Put and drilled.
B：Jing greater psoas muscles approach after peritonaeum
Patient is placed in lateral position, and the incision of abdominal wall directly over sick vertebra, passivity separates abdominal wall muscle, is arrived at by spatia retroperitonaeale
Greater psoas muscle surface, progressively expands the psoas major space after Fluoroscopy location, reach centrum side, in pedicle of vertebral arch height, 1/2 after centrum
Put and drilled.
Chinese patent literature CN102028532A discloses a kind of nanocomposite intervertebral fusion cage, upper and lower with insertion
The upper and lower ends face of the nonmetallic materials basal body structure of the centre bore of end face is the matsurface for being provided with dentalation, in basal body structure
Side be provided with the side opening connected with centre bore, be provided with one in the leading section of basal body structure use direction or rearward end threaded
Clamping hole, two on a pair of angular direction of the both sides with indent clamp structure basal body structure upper surface or lower surface in its outer aperture
Side is respectively provided with a coplanar metal location structure, and in the non-clamping hole place end of basal body structure other end one is additionally provided with
Antarafacial metal location structure.Chinese patent literature CN201612682U discloses a kind of posterior lumbar interbody fusion device, including one
Fusion device body, thereon, lower surface be provided with it is anti-skidding swing to sawtooth, the fusion device is integral structure body of the appearance in fusiformis；
Its front end is be easy to squeeze into bullet-headed, and the upper and lower surface at middle part and left and right side are convex surface arc-shaped, the fusion device
Bone grafting cavity is provided with body.But it is current also not with regard to the centrum booster for the treatment of compression fracture of vertabral body of the present utility model
Appear in the newspapers.
