Description
Technical field
The present invention relates to a kind of spinal fracture way of escape for spinal surgery and quantize distraction reduction external fixer.
Background technology
Spinal fracture is one of common wound, and especially lumbar vertebra compression fracture is clinical the most common, for the lumbar vertebra compression fracture of not accompanying nerve injury, except a part, slightly fractures without operative treatment, and majority needs operative treatment.
Along with the aging of population, osteoporosis sickness rate obviously increases, and approximately there are 200,000,000 sufferers of osteoporosis face in the whole world at present, and China estimates at 5,000 ten thousand left and right.Osteoporotic vertebral fracture is also a large type of lumbar vertebra compression fracture.
Traditional cut multiple internal fixation and have large, the hemorrhage shortcomings such as many of wound, compare with traditional open surgery, the target of invasive surgery formula is to reach the clinical efficacy same with traditional operation with minimum wound.
The non-osteoporotic thoracolumbar fracture micro-traumatic fracture reduction fixer tool using at present comprises Sextant, frame-type plus-minus screw bolt angle nail basefixer for spine etc.The Therapeutic Method of osteoporotic compressed fracture of thoracic vertebra and lumber vertebra comprises protruding plasty etc. after percutaneous vertebroplasty and percutaneous.
But no matter be non-osteoporotic impassivity damage lumbar vertebra compression fracture or osteoporotic compressed fracture of thoracic vertebra and lumber vertebra, all exist with clinicist personal experience and reset, lack the index that instructs of a quantification, thereby cause the generation of the complication such as unnecessary broken nail, stub and lifelong hunchback, operative failure, adjacent vertebra folding.
Summary of the invention
The many complication that cause for fear of unreasonable reset, we have designed this spinal fracture way of escape and have quantized distraction reduction external fixer.This apparatus can help spinal surgery doctor to reach spinal fracture quantification, limited reposition, rationally reset.
The present invention is achieved by the following technical solutions:
1, this spinal fracture way of escape quantizes distraction reduction external fixer and with pitman and one, fixes pullover, removable pullover, a removable rod of exerting pressure, a hydraulic pressure sacculus and an instrument and form by two pieces of hollow screws, one are fixing.
2, hollow screw head is provided with a plurality of apertures, and afterbody is provided with nut, nut internal diameter and cap nut external diameter coupling, and bone cement can arrive around screw by aperture, strengthening nail road.
3, the fixing pullover screw duct that is provided with, screw duct internal diameter is consistent with hollow screw external diameter, and hollow screw is just in time through screw duct.
4, in fixing pullover major axis, be hollow channel, for mobile rod and the hydraulic pressure sacculus of exerting pressure is installed.
5, hollow channel one lateral section size is consistent with the mobile club head cross-sectional sizes of exerting pressure, and opposite side cross-sectional sizes is consistent with the mobile barred body portion cross section of exerting pressure.
6, the hollow channel in mobile exert pressure club head and fixing pullover major axis accompanies hydraulic pressure sacculus.
7, hydraulic pressure sacculus is by instrument connector extension instrument.
8, the mobile barred body standard laid down by the ministries or commissions of the Central Government of exerting pressure has scale.
9, a removable pullover screw duct, a movement exert pressure excellent passage and the lock screw of being provided with, the mobile rod of exerting pressure is installed to removable movement on pullover and exerts pressure after excellent passage, is screwed down lock screw and can fixes the mobile rod of exerting pressure.

In figure: 1. hollow screw; 2. aperture; 3. screw hollow channel; 4. nut; 5. nut female thread; 6. screw duct; 7. hollow channel; 8. instrument connector; 9. instrument; 10. scale; 11. move the rod of exerting pressure; 12. hydraulic pressure sacculus; 13. move the barred body portion that exerts pressure; 14. move the club head of exerting pressure; 15. is fixing pullover; 16. is removable pullover; 17. lock screws; 18. move the excellent passage of exerting pressure; 19. is fixing with pitman; 20. cap nuts.
The specific embodiment
After apparatus sterilizing sterilization, carry out body surface marking with it planning to implement the lumbar vertebra compression fracture minimal invasion outer fixing patient that resets, skin incision, under X-ray C arm machine or navigator are assisted, inserts Kirschner wire in pedicle of vertebral arch.Get structure after mobile exert pressure rod and fixing pullover assembling (production out mobile exert pressure rod and fixing pullover assembling is exactly what fit together), one piece of hollow screw 1 is set to 6 li, screw duct on fixing pullover 15.Assistant helps to buttress fixing pullover, and operator is screwed into pedicle of vertebral arch by hollow screw 1 along Kirschner wire, transfers to Kirschner wire.Get removable pulloverly 16, be inserted in one piece of hollow screw on screw duct 6 thereon, assistant helps to buttress removable pullover, and operator is screwed into homonymy pedicle of vertebral arch by hollow screw 1 along Kirschner wire, transfers to Kirschner wire.Two pieces of hollow screws are screwed into and approach after same plane, removable pullover 16 movement is inserted in in the mobile barred body portion 13 that exerts pressure and exerts pressure in excellent passage 18, after location confirmation, tighten lock screw 17.For sufferers of osteoporosis face, according to bone density size, the patient who estimates to follow closely strengthening is treated to its aperture by hollow screw head permeates into around hollow screw toward injecting bone cement in hollow screw, for there is no sufferers of osteoporosis face, without injection bone cement.Then by fixing, with pitman 19, be set in the nut 4 of two pieces of hollow screws, get 20 two of cap nuts, be screwed to respectively in the nut 4 of two pieces of hollow screws, first tighten wherein one piece of cap nut, by supporting reduction instrument, carry out distraction reduction, in the process of continuous distraction reduction, because two pieces of screws strut, pull the mobile rod 11 of exerting pressure to both sides, the mobile club head 14 feeding pressure ball capsules 12 of exerting pressure are exerted pressure, and corresponding pressure size shows by instrument 9.Operator should be noted the data in instrument 9 and moves the scale of the barred body portion that exerts pressure.When reaching, reasonably strut after size, tighten another piece of cap nut.Same method row offside operation.For sufferers of osteoporosis face, can inject bone cement hindering in vertebra of resetting, the present invention is postoperative just dismountable, for without fixing a period of time of sufferers of osteoporosis face and part sufferers of osteoporosis face, until remove the present invention after union of fracture.
