Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of spine fracture auxiliary operative reduction and bone grafting it is different
Shape stick.
Background technique
Spine fracture is the common wound of orthopaedics.Its incidence accounts for the 5%~6% of fracture, most with thoracolumbar fracture incidence
Secondly height is neck, lumbar vertebrae, thoracic vertebrae is minimum, often can concurrent spinal cord or cauda equina injury.The common male of spine fracture is between twenty and fifty,
Mostly caused by indirect external force, for buttocks when being fallen from eminence or foot lands, impact external force is fractured to chest waist section is uploaded to.
Clinical manifestation is deformity, the pain of wound posterior spinal, often can concurrent spinal cord injury.
The common treatment method of spine fracture provides the support force of healing growth simultaneously to hurt vertebra for nail stick orthopedic fixation system
It is orthopedic to bending section progress, to cure spine fracture.Nail stick orthopedic system is made of pedicle screw and connecting plate, vertebral arch
For root screw by pedicle of vertebral arch position and squeezing into centrum, pedicle of vertebral arch screw, which nails on, is fixedly connected with stick, by the support of pitman and leads
Regard it as and completes to hurt the self-healing of vertebra and orthopedic.
However in existing spine fracture surgical procedure, lack corresponding auxiliary tool, clinician is difficult to strut wound
The disc height of vertebra deforms injury and loses physiological curve arc to fill autologous bone or allograph bone to its fracture gap
The vertebra of hurting of degree carries out effective Retracting repositioning.
Utility model content
The utility model to solve the above-mentioned problems, devises the abnormity of a kind of spine fracture auxiliary operative reduction and bone grafting
Stick, which can strut in spine fracture surgical procedure hurts vertebra vertebral height to its fracture gap filling autologous bone or allosome
Bone provides support force, at the same can also carry out the reset of physiological curve radian to the vertebra section of injury deformation with complete to hurt vertebra it is orthopedic to
The healing of vertebra is hurt in quickening.
In order to achieve the above technical purposes, reach above-mentioned technical effect, the utility model is real by the following technical programs
Existing:
A kind of spine fracture assists the profile bar of operative reduction and bone grafting, which is characterized in that including profile bar, described is different
Shape stick is cylindrical bar, and the both ends of profile bar are straight section, and interlude is segmental arc, after profile bar both ends straight section rotates 20 degree and
It is consistent with the physiological camber of backbone to be formed by angle；
The diameter of the profile bar is 5.5mm, and total length 70mm, the span of segmental arc is 20mm, the arch of segmental arc
A height of 15-20mm.
Preferably, the profile bar selects ti-ni shape memory alloy material to be made.
The beneficial effects of the utility model are: the profile bar can strut in spine fracture surgical procedure hurts vertebra vertebral height
Autologous bone is filled to its fracture gap or allograph bone provides support force, while can also carry out physiological curve to the vertebra section of injury deformation
Radian is resetted to complete to hurt the orthopedic healing for hurting vertebra to quickening of vertebra.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
Refering to fig. 1 shown in -4, a kind of spine fracture assists the profile bar of operative reduction and bone grafting, including profile bar 1, described
Profile bar 1 be cylindrical bar, the both ends of profile bar are straight section, and interlude is segmental arc, 1 both ends straight section of profile bar rotation 20
It is bent consistent with the physiology of backbone after degree；
The diameter of the profile bar 1 is 5.5mm, and total length l is 70mm, and the span d1 of segmental arc is 20mm, segmental arc
Sagitta h be 15-20mm.
Therein, the profile bar 1 selects ti-ni shape memory alloy material to be made.
One concrete application of the present embodiment are as follows: the positioning of pedicle screw 2 drills and is mounted and fixed to such as routine
Step, pedicle screw 2 be installed on the bone face between the transverse process 41 of pedicle of vertebral arch 4 and spinous process 42 and by the screw thread of rivet nut 21 with
The bone face of pedicle of vertebral arch and the bite force of centrum 3 are fixed on pedicle of vertebral arch 4；Pedicle of vertebral arch 4 each side fixes a pedicle of vertebral arch
Screw and double screw is formed in the first vertebra section 5 and third vertebra section 7, by the straight section at 1 both ends of profile bar respectively to segmental arc pair
Two straight sections are individually fixed in the first vertebra section 5 and third vertebra section 7 in rivet nut 21 after curved 20 degree of the center point answered, use cock 22
It being limited in the card slot of rivet nut 21, profile bar 1 is equipped with two and is respectively limited by the two rows of pedicle screw 2 in left and right,
It, which rotates by a certain angle to spinous process side, after profile bar 1 is fixed, which makes it expose the second vertebra section 6, enters to follow closely a little；Due to profile bar
1 is made of memory alloy material, during cock 22 is tightened, profile bar both ends revert to straight section during pull
One vertebra section 5 and third vertebra section 7, the first vertebra section 5 and third vertebra section 7 during being reset to physiological camber collective effect in second
Vertebra section 6 makes it be reset to initial physiological camber；First vertebra section 5 and the second vertebra section 6 and the second vertebra section 6 and third vertebra section 7 simultaneously
Between disc height be softened, autologous bone or allograph bone are injected into its fracture gap at this moment；After injection, unscrewing
Cock simultaneously removes profile bar 1 and the pitman of pre-bending is fixed on pedicle screw 2, and spine fracture orthopedic fixation can be completed
Operation.
In addition, the total length of profile bar 1 and the length of segmental arc can do it is longer, with complete hurt the more spinal bones of vertebra section
The reset and bone grafting rolled in surgical procedure assist operative treatment.
