Description
Technical field
The invention belongs to technical field of medical equipment, it is related to a kind of simple in structure, easy to use body capable of being protected to give birth to
The spinal orthosis of long potential.
Background technology
Human spine is in growth course, when centrum develops existing defects, in fact it could happen that scoliosis, hunchback, backbone
The deformities such as preceding prominent, scheuermann kyphosis, the cubical content that scoliosis normally results in thoracic cavity, abdominal cavity and pelvis reduce, also
The growth that height may be limited, it is larger to the harmful effect of human body.Therefore, in medical domain, how effectively to child and blueness
Juvenile scoliosis carries out orthopedic being always the problem of those skilled in the art pay close attention to.Currently, the used therapeutic scheme of backbone correcting
Main process it is as follows：According to the vertebral column development situation of patient, preoperative preparation is carried out；By performing the operation rod-shaped correction
Item be implanted into human body, be used in combination nail stick by correct item fixed with backbone, typically the both sides of backbone it is each fix one correct item, to
Backbone is along the channeling direction growth of correction item, and to play the role of correcting backbone, finally, suture operation is open.
Backbone correcting is to be connected two Orthopedic rods with hard metal bar at present, can make Orthopedic rod in this way and consolidate
A frame structure is formed between fixed nail, its advantage is that whole link rigidity is improved, the disadvantage is that limiting the flexibility of backbone
And growth potential, meanwhile, the connector of existing spinal orthosis tends not to freely adjust link position, in surgical procedure
It is restricted relatively strong, surgical effect is influenced, injury is generated to human body, influences backbone normal growth, therefore researches and develops one kind to protect
The spinal orthosis of body growth potential.
Invention content
The purpose of the present invention is to provide a kind of backbones simple in structure, easy to use that can protect body growth potential
Orthopedic appliance.
The object of the present invention is achieved like this, including Orthopedic rod and connector, and the Orthopedic rod is arranged in parallel and by even
Fitting is attached fixation, and the connector includes fixed block and connecting rope, and pilot hole and Orthopedic rod is arranged on the fixed block
It is slidably matched, lock-screw is set on the fixed block and is coordinated with Orthopedic rod locking, connecting hole is additionally provided on the fixed block,
Fixed block is attached by the connecting rope passed through in connecting hole.
The connector of the present invention is set as fixed block and connect the cooperation of titanium hawser, and the pilot hole on fixed block can be along orthopedic
Stick slides up and down, and can freely adjust installation site and link position, while facilitating operation to carry out, avoids being not suitable in human body
Place the position of excessive volume instrument；Fixed block is small, and edge is respectively provided with chamfering or rounding, reduces instrument pair
The injury of human body, the connecting hole being arranged on fixed block, and the connection titanium hawser by being passed through in connecting hole connects Orthopedic rod
It connects and limits, use rope connection flexible, do not limit the displacement that two Orthopedic rods are mutually drawn close, only limit two Orthopedic rods
Split displacement, thus maintain the certain flexibility of backbone and growth potential.The configuration of the present invention is simple, user when operation
Just, not only overall volume is small, can adjust link position, reduces the injury to human body, moreover it is possible to protect the growth of backbone.
Description of the drawings
Fig. 1 is structure of the invention figure；
Fig. 2 is the overlooking structure figure of connector in Fig. 1；
In figure：1- fixed blocks, 11- pilot holes, 12- connecting holes, 2- lock-screws, 3- connecting ropes, 4- Orthopedic rods.
Specific implementation mode
The present invention will be further described below with reference to the drawings, but must not be limited in any way to the present invention,
Based on present invention teach that made by any changes and modifications, all belong to the scope of protection of the present invention.
As shown in Figure 1 and 2, the present invention includes Orthopedic rod 4 and connector, the Orthopedic rod 4 be arranged in parallel and by connector into
Row is connected and fixed, and the connector includes fixed block 1 and connecting rope 3, and pilot hole 11 and Orthopedic rod 4 is arranged on the fixed block 1
It is slidably matched, lock-screw 2 is set on the fixed block 1 and is coordinated with the locking of Orthopedic rod 4, the company of being additionally provided on the fixed block 1
Hole 12 is connect, fixed block 1 is attached by the connecting rope 3 passed through in connecting hole 12.
The fixed block 1 is set as cylindrical, and the pilot hole 11 is arranged concentrically with fixed block 1, the height of the fixed block 1
Degree a is 10 ~ 25mm, a diameter of 8 ~ 20mm, the edge setting chamfering or rounding of the cylinder fixed block.
The fixed block 1 is set as box-shaped, the pilot hole 11 be arranged the center of fixed block 1 and with fixed block 1
Height end face is vertical, and the corner of the fixed block 1 is set as chamfering or rounding, and the height a of the fixed block 1 is 10 ~ 25mm,
Length and width is set as same size and length and width values b is 8 ~ 20mm.
Screw hole is set perpendicular to pilot hole 11 on the fixed block 1, lock-screw 2, the locking are set in the screw hole
2 inner end of screw and 4 Stop-motion lock tight fit of Orthopedic rod.
The connecting hole 12 is set as semicircular ring, and the thickness h size of semicircular ring is 2 ~ 5mm, and the setting of the connecting hole 12 exists
The middle part of the side of fixed block 1.
The connecting hole 12 is vertically arranged, and connection hole face and 11 center line of pilot hole are in the same plane.
