Description

A kind of child's scoliosis is helped growing rod

Technical field

This utility model belongs to the medical apparatus and instruments for the treatment of child scoliosis, and particularly a kind of child's scoliosis is helped growing rod.

Background technology

Prevent increasing the weight of of rachiocamposis carrying out the general Ha Shi of employing of Rachiocampis correction operation separation bar, promote the longitudinal growth of trunk.Under the support of Ha Shi separation bar, spinal column is grown to lengthwise, along with growing, regularly do gradation and strut, help the through skeletal maturation of spinal growth, epiphyseal arrest, a kind of good method increased the weight of for preventing spine bending, preventing that lateral bending from increasing the weight of and to accelerate in the lengthwise growth of trunk effect remarkable.Height deducts length that preoperative height equals to strut and adds and grow the length increased when finally following up a case by regular visits to.In the situation that inner support, spinal column is subject to vertically to strut the impact of power, has accelerated the speed of longitudinal growth, just consistent with the theory of Ilizarov distraction osteogenesis, produces " quantitative change " in chronic traction process, makes spinal column follow growing and extends gradually.Can only the disposable power of strutting play a supportive role but be used in child's scoliosis orthopedic, after the height of infant increases, just lost the effect of correcting scoliosis.The Ha Shi rod is an one rod, can't reaching as required of rod itself automatically prolongs, be used in child's scoliosis orthopedic, can not put in advance longer Ha Shi separation bar, but child's spinal column can increase year by year, at this moment Ha Shi separation bar is just ineffective, certainly will will carry out the secondary major operation and change the Ha Shi separation bar.

Summary of the invention

The purpose of this utility model is to provide a kind of child's scoliosis to help growing rod, not only can prevent that rachiocamposis from increasing the weight of, promote the longitudinal growth of trunk, and be particularly suitable for treating child's scoliosis, the growth that can follow the infant spinal column increases, the effect of performance assisting growth and correction deformity, stop until epiphyseal arrest is grown.

The purpose of this utility model is achieved in that a kind of child's scoliosis helps growing rod, comprise the uniform Ha Shi separation bar that fore shaft is being set in top, be installed with and rise to the bait on the fore shaft of Ha Shi separation bar, bottom in the Ha Shi separation bar is arranging sleeve pipe, with sleeve pipe core bar its underpart movingly, the spring catch platform is being set, on the lower end of Ha Shi separation bar sleeve pipe and the core bar between core bar spring catch platform, Compress Spring is installed, below core bar spring catch platform, inserting column is being set, match with the inserting column of core bar in seat hole with lower its Connection Block of hook of Connection Block, the mouth of hook of rising to the bait upwards, the mouth of hook of lower hook is downward.

This utility model has increased the elasticity device for spreading on the basis of Ha Shi separation bar, the growth that can follow spinal column increases, strut gradually prolongation, add and within every 6-12 month, do a gradation and strut (minor operation), until rachiocamposis is corrected and the vertebral column development maturation.

This utility model is done packaged tube in the lower end of Ha Shi separation bar, pipe range 90mm, sleeve pipe and core bar socket-connect, on core bar with spring, its lower end inserting column can insert in the seat hole of lower hook Connection Block, and the growth of following spinal column in the human body of packing into plays elasticity and struts and extend.When spring flicks while reaching certain limit, the method that also can adopt little otch gradation to strut, make that spring is further compressed has again regenerated the effect of helping flicked.

This utility model operation technique program:

First step otch and exposure: along infant spinous process otch, only expose one-sided vertebral plate.Because not making bone grafting, without the soft tissue by adhering on vertebral plate, thoroughly do not divest totally.Only stage casing need to be worn to a few joint vertebral plate lids of Luque steel wire and window, sting except interspinal ligaments and ligamenta flava, expose dura mater and can wear the Luque steel wire.

Second step hook: above be hooked in the joint space of thoracic vertebra inferior articular process of the recessed side of lateral bending, under be hooked on the upper limb of the full vertebral plate of lumbar vertebra.

The 3rd step is worn steel wire under vertebral plate: at the vertebral plate Xia Chuan 2-4 road in otch stage casing Luque steel wire, prepare to fix with growing rod.

The 4th step is installed growing rod: growing rod is inserted in the dog hole of upper and lower hook, under platform, under personnel's a foot traction, is strutted the rectification lateral bending.Next step by Luque fixation with steel wire under vertebral plate on rod.

The 5th step Luque fixation with steel wire rod: the Luque forming from steel wire is fastened on rod, rod is contacted with vertebral plate, to strengthen interior fixing stability, also there is the effect that lateral pull is corrected scoliosis.

The 6th step is closed layer after fascia thoracolumbalis: hook, rod are imbedded in Musclar layer.This practice is difficult for breaking off relations than rod being placed on to safety in subcutaneous tissue, also can not touch hook and rod across skin.

The 7th step: hemostasis, cleaning wound, place negative-pressure drainage tube, the close incisions operation finishes.

To infant undergoing surgery through Long-term, proof is under the support of assisting growth rod, can make spinal column to vertical growth, along with growing and crooked rectification, elastomeric spring flicks gradually, can also be at the pagoda fore shaft end of separation bar, strut do gradation with little otch, make to help growing rod and can between the longer period of development, prevent scoliosis, promote the effect of spinal column longitudinal growth, help the infant growth promoter, stop until epiphyseal arrest is grown.
