Abstract
The invention discloses a kind of Orthopedic rod can be made freely to stretch and with the connector of angle compensation function, including connector body, multi-directional ball and lock-screw, the connector body is provided with Orthopedic rod and penetrates hole, vertical Orthopedic rod penetrates hole and sets locking hole to coordinate with lock-screw, one side wall is provided with extension on the connector body, spherical pore is provided with the extension, multi-directional ball is installed in the spherical pore, both are rotatably assorted, and are provided with that Orthopedic rod penetrates hole and to penetrate hole with the Orthopedic rod on connector body parallel in the multi-directional ball.After using this connector, two Orthopedic rods are connected, solve and insert the problem that long rod wears rod connection difficulty, two rods can be made freely vertically move relatively, while suitable control deformity of spine, induce the backbone longitudinal direction free growth of deformity, the setting of multi-directional ball can make two rods realize opposing oscillatory in certain angle, reduce the constraint moved left and right to backbone, increase the pliability of backbone.
Description
Technical field
Medical apparatus and instruments technical field of the present invention, and in particular to one kind can make Orthopedic rod freely stretch and be mended with angle
Repay the connector of function.
Background technology
Deformity of spine refers to one of backbone or the bending of several segments deviation midspinal line, generally entails the rotation of centrum
With processus aboralis in sagittal plane or preceding prominent increased or decrease.It is a kind of three-dimensional deformity of spine, its incidence in teenager about
0.5-2% or so, can be as caused by a variety of diseases.When scoliosis angle is excessive, or obvious progressive trend is presented, just need
Consider operative treatment；Otherwise serious and stiff deformity of spine can be gradually developed into, seriously affects heart and the breathing of infant
Function, influencing spinal function causes to paralyse, or even life-threatening.The main purpose of operative treatment is to prevent deformity progress, recover
Spine balance；Correction deformity as far as possible.The basic principle of surgical orthopaedic is carried out to deformity of spine at present, that is, is based on being fixed on ridge
The metal grappling utensil (such as pedicle screw, hook, steel wire) of different parts, is connected, at the same time by strong metal bar on column
It is orthopedic by instrument application optical force progress, and force that backbone is fixed and merged.
Clinically, in order to strengthen the intensity fixed to backbone, or in the segment that backbone has been fixed extension fixation is carried out, and
In the growing rod treatment of children's early onset deformity of spine, it is often necessary to carry out coupling between rod and rod, mesh using connector
Preceding most-often used connector connector between rod, the original intention of connector design are reliably to obtain the stabilization between rod and rod
Connection, its structure type is, on a tetragonal body, processes 2 parallel holes, lock-screw is machined with hole wall, needs
The head of two rods of connection respectively penetrates tail in the two holes, then is compressed and locked with lock-screw, that is, completes connection, such as.
However, using connector treatment children's early onset deformity of spine between existing rod, there are obvious drawback.On the one hand, often
Be required to row operation once every regular time (general 6-9 month), to appear connector, one side unclamp its couple with rod it is tight
Gu screw, and use struts strength and children's backbone is obtained limited extension, it is therefore an objective to it is the growth headspace of backbone；Thus it is anti-
Plural time, or even after tens of times, necessarily high postoperative complication is brought to operation.On the other hand, it is complete between Orthopedic rod
Locked and fixed, Orthopedic rod, which can not be realized, freely to be stretched, and limits backbone free growth, and do not meet the original of current biologic treatment
Then.Having developed one kind for this can allow Orthopedic rod freely to stretch, while with the multipurpose connector of swing angle compensation
With very major and immediate significance.
The content of the invention
The object of the present invention is to provide a kind of Orthopedic rod can be made freely to stretch and with the connector of angle compensation function.
The object of the present invention is achieved like this, including connector body, multi-directional ball and lock-screw, the connector
Main body is provided with Orthopedic rod and penetrates hole, and vertical Orthopedic rod penetrates hole and sets locking hole to coordinate with lock-screw, the connector
One side wall is provided with extension in main body, and spherical pore is provided with the extension, multi-directional ball is installed in the spherical pore, both
It is rotatably assorted, is provided with that Orthopedic rod penetrates hole and to penetrate hole with the Orthopedic rod on connector body parallel in the multi-directional ball.
After two Orthopedic rods are connected using this connector, solve and insert the difficulty that long rod wears rod connection difficulty
Topic, can make 1# Orthopedic rods relative to 2# Orthopedic rods freely vertically move, while suitable control deformity of spine, induction
Deformity backbone longitudinal direction free growth, avoid the constraint to spinal growth, and avoid repeatedly strut repeatedly extension operation and
Threat of the spinal cord stretching for spinal function, the setting of multi-directional ball can make 1# Orthopedic rods relative to 2# Orthopedic rods at certain angle
Swung in degree, reduce the constraint moved left and right to backbone, increase the pliability of backbone, therefore be significantly reduced due to one end
Backbone is fixed the two spontaneous fusion risks brought.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention；
Fig. 2 is the schematic top plan view of Fig. 1；
In figure：1- connector bodies, 11- extensions, 2- multi-directional balls, 3- lock-screws, 4-1# Orthopedic rods, 5-2# are orthopedic
Rod.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings, but the present invention is not any limitation as in any way, is based on
Present invention teach that any conversion made, each falls within the scope of the present invention.
As shown in Figure 1 and 2, the present invention includes connector body 1, multi-directional ball 2 and lock-screw 3, the connector body
1, which is provided with Orthopedic rod, penetrates hole, and vertical Orthopedic rod penetrates hole and sets locking hole to coordinate with lock-screw 3, the connector master
One side wall is provided with extension 11 on body 1, and spherical pore is provided with the extension 11, multi-directional ball 2 is installed in the spherical pore,
Both are rotatably assorted, and Orthopedic rod is provided with the multi-directional ball 2 and penetrates hole and penetrates Kong Ping with the Orthopedic rod on connector body 1
OK.Orthopedic rod penetrates the diameter in hole according to the difference of Orthopedic rod diameter, there is different specifications.Penetrate multi-directional ball 2 another rectifys
Shape rod, can slide in the hole of multi-directional ball 2, can also do certain swing with the rotation of multi-directional ball 2.
The connector body 1 is square, cuboid or cylindrical structure.
Equal rounded corner when the connector body 1 is square or cuboid.
The extension 11 is an integral structure with the connector body 1.
The locking hole at least sets one.
The connector body 1 is titanium alloy material.
The extension 11 is titanium alloy material.
The operation principle and process of the present invention：
During using this connector, first lock-screw 3 is loosened, the Orthopedic rod that 2# Orthopedic rods are penetrated to connector body 1 is worn
Enter in hole, the length that traversing through end Orthopedic rod stretches out is 2 ~ 4mm.Lock-screw 3 is tightened, with lock-screw 3 by Orthopedic rod pressure
It is tight and fixed.1# Orthopedic rods are penetrated in the hole of multi-directional ball 2 again, the extension elongation of traversing through end Orthopedic rod is 8 ~ 20mm.1# is orthopedic
Rod can slide in the hole of multi-directional ball 2, and when Orthopedic rod needs to swing compensation, multi-directional ball 2 rotates, and drives 1# Orthopedic rods to turn
It is dynamic, meet the needs of Orthopedic rod swing.
