Description
Technical field
The utility model relates to medical instruments fields, more particularly to a kind of scoliosis orthopaedic aid.
Background technique
Scoliosis is commonly called as scoliosis, and the backbone of normal person should be straight line from i.e. coronal-plane is seen below, and
Trunk two sides are symmetrical, and X-ray film shows that backbone has the side greater than 10 degree to be bent (referring to Fig.1), can be diagnosed as scoliosis.Ridge
Column side is convex, patient body can be made to deform, and serious person also will affect cardio-pulmonary function, even involve spinal cord, causesParalysis, therefore need
It is corrected according to the degree of scoliosis.
Currently, operation is to treat the effective way of scoliosis, according to the situation of scoliosis, the ridge for needing to correct is determined
Vertebra is disposed in the pedicle of vertebral arch of these vertebraes into pedicle screw, and the tail cap part of pedicle screw connects with Orthopedic rod, uses
Pedicle screw is cascaded by Orthopedic rod, is aligned using Orthopedic rod to vertebra.
Since human spine has physiological bending, Orthopedic rod need to prepare the form for meeting physiological bending, while side is convex
The backbone of deformity has certain bending angle again, therefore doctor needs in face of many difficult during placing Orthopedic rod, and
And it is traditional it is orthopedic during need to revolve stick, when revolving stick, backbone is waved obviously, spinal cord mind big to spinal nerve drawing amplitude
The risk for being subjected to damage is higher；Secondly, being easy to appear evil between Orthopedic rod and pedicle screw and between pedicle screw
Sex resistance leads to loosening, disconnected stick, broken nail occur.
Utility model content
The purpose of this utility model is to provide a kind of scoliosis orthopaedic aid regarding to the issue above, this backbone side
Convex orthopaedic aid is more convenient with the connection of pedicle screw, and the physiology that human spine can be voluntarily adapted to after connection is curved
Song can carry out good correction to scoliosis using it, guarantee the smooth implementation of operation.
In order to achieve the above objectives, the utility model includes an aligning column and spaced multiple connection frames, connection frame
With first sleeve, second sleeve, first sleeve and second sleeve are spatial vertical relationship, and aligning column sequentially passes through each connection frame
The inner hole of upper first sleeve is coated with the extension rod for connecting with pedicle screw in second sleeve.
