Abstract
The invention discloses a minimally-invasive thoracolumbar vertebral fracture repositor. The minimally-invasive thoracolumbar vertebral fracture repositor is formed by a left clamp, a right clamp, regulating nuts, regulating screw rods, a pin, a movable pin, a left clamp handle and a right clamp handle, wherein the left clamp, the right clamp, the left clamp handle and the right clamp handle are integrated, the left clamp handle and the right clamp handle are provided with the regulating screw rods and the regulating nuts, the movable pin is used as a pivot by the left clamp and the right clamp, and two clamp heads are both provided with semi-circle notches. The minimally-invasive thoracolumbar vertebral fracture repositor disclosed by the invention has the characteristics that the structure is reasonable, the surgery is simple, the operation is convenient, the location is accurate, the curative effect is good, the cost is low, the pain of a patient is light, the economical burden is less, and the like; and the problems, such as large surgery wound, long time and great pain of the patient, existing for a long time, are solved, the strut reposition of a fractured vertebral body can be quickly carried out through a minimally-invasive incision channel, the surgery time is saved, the pain of the patient is relieved, the curative effect is obvious, and the minimally-invasive thoracolumbar vertebral fracture repositor is an ideal reposition surgery mating instrument dedicated for minimally-invasive treatment of thoracolumbar vertebral fracture.
Description
Technical field
The present invention relates to is medical apparatus and instruments, more particularly is about bone surgery set, is used for the treatment of Wicresoft's chest lumbar vertebra fracture restorer of the reduction of the fracture such as breast lumbar vertebra operation.
Background technology
Lumbar vertebra compression fracture is common spinal fracture, traditional operation is to reset fracture site fixing with pedicle screw, pedicle screw is because having the fixing advantage of three posts, applied, but its modus operandi is to adopt to open to carry on the back to insert pedicle screw, and it is to cut at human body back median incision, peels off to both sides along otch, wound large, hemorrhage many, the hospital stays is long, has increased patient's slight illness and financial burden; Need expansion peel off paraspinal muscle in the operation, easily cause paraspinal muscle forfeiture innervation, cause the dysfunction in late period, often suffer from rear lumbar and back pain, the complication such as stiff.In clinical, existing pedicle screw apparatus only is that conventional therapy is designed and use, operation bothers, wound is large, the patient suffering is large, insert in the pedicle of vertebral arch screw tack operation at percutaneous puncture, the importing process difficulty of inserting and indulging rod for screw is very large, therefore can not be used for fixedly lumbar vertebra compression fracture of multi-segmental.Only have large otch to use pliers to strut for resetting of vertebra, more strengthened patient's misery, therefore, a kind of for the minimally-invasive treatment operation for thoracolumbar fractures in the urgent need to developing, can utilize the little otch passage of Minimally Invasive Surgery to carry out the apparatus of anterior vertebral distraction reduction, come to satisfy operation and clinical in actual demand, to alleviate patient suffering and financial burden.
Summary of the invention
The object of the present invention is to provide and a kind ofly can eliminate above-mentioned shortcoming, have Wicresoft's chest lumbar vertebra fracture restorers rational in infrastructure, the characteristics such as operation is simple, easy to operate, accurate positioning, good effect, cost is low, the patient suffering is light, financial burden is little.Especially adopt split type hand vice structure, two calipers can by Wicresoft's open channel respectively segmentation insert reduction point, prop up vertebra after two calipers fasten, play the effect of accurate distraction reduction.Having captured the difficulty that struts anterior vertebral in the operation by mini-incision, simplified simultaneously operation technique, reduced operation wound, saved operating time and convalescence, is the supporting apparatus that resets of desirable minimally-invasive treatment lumbar vertebra compression fracture special use.
Wicresoft of the present invention chest lumbar vertebra fracture restorer or title open mouth tongs are made of left and right clamp piece, adjusting nut, adjusting screw(rod), pin, movable latch, left and right pliers grip, wherein, wherein, clamp piece and pliers grip are integrated, at left and right pliers grip adjusting screw(rod) and nut are housed, left and right clamp piece interlocks take movable latch as fulcrum, two clamp piece fastening degree are enough to freely to open or are closed, do not swing or rock and can not produce, all leave half round cut on two binding clips, be convenient to the clamping vertical connecting rod and find the anterior vertebral of naming a person for a particular job accurately and strut.
The invention belongs to one of serial lumbar vertebra compression fracture way of escape mis instruments, through mini-incision distraction reduction anterior vertebral, it can select medical metal material to be processed into, and preferably selects the medical stainless steel material in being mainly used in performing the operation, long service life is convenient to the Reusability of sterilizing.
Use procedure at serial apparatus: patient's general anesthesia, the patient body ventricumbent position, abdominal part is unsettled.Telltale mark is hindered vertebra and the pedicle of vertebral arch body surface projection of vertebra up and down thereof under the C arm machine, along the conventional entry point center pillar to the vertebral body that punctures, insert three pieces of guide pins, the lower definite guide pin position of C shape arm perspective is good, centered by every piece of guide pin, do longitudinal incision, be about 1.5 cm, cut skin and deep fascia, use the designed step by step expanding sheath cartridge system of the present invention, adjust sleeve pipe by thin to passivity expansion paraspinal muscle step by step successively slightly, make all sleeve pipes groove suitable for reading of a side be in same straight line (this moment sleeve pipe under port recess also be in same straight line), use Kirschner wire and fix all sleeves in the transverse process root of place vertebral body, take out all the other sleeves in the outer sleeve, use hollow screw tap tapping along guide pin, screw openings device opening, use designed screw inserter to be screwed into common pedicle screw hindering on the vertebra the next vertebral body, hinder vertebra and be screwed into Universal pedicle screw, re-use the direction that connecting bar (or claiming connection handle) is adjusted the U-shaped groove of pedicle screw nail tail one by one, make the complete sleeve slot opening of itself and adjusted direction consistent.Selecting appropriate length angle hold-down bars is vertical connecting rod, by hindering the skin incision of the upper vertebral body screw of vertebra, pasting vertebral plate interts one by one to the next screw, left and right sides clamp piece is respectively by 2 mini-incision passages of vertebra the same side, connect take movable pin as fulcrum, and with anterior vertebral strut, screw tail medicated cap locking hold-down bars.Prepare implant bed between vertebral plate with the dentation curet, Trephine for spondylopathy Wicresoft takes from the body ilium, utilize Wicresoft's pressurization bone grafting instrument capable after outside bone grafting.Find to have outstanding effect through clinical practice, satisfy reduction of the fracture requirement by mini-incision, otch carries out and do not need separately.
Wicresoft of the present invention chest lumbar vertebra fracture restorer has solved the problem of the existence such as the operation for thoracolumbar fractures wound is large for a long time, the time is long, the patient suffering is large, can pass through the mini-incision passage, carry out fast the anterior vertebral distraction reduction, saved operating time, alleviated the patient suffering, evident in efficacy, be the supporting apparatus of reattachment surgery of desirable minimally-invasive treatment lumbar vertebra compression fracture special use.
