Description
Technical field
Medical apparatus and instruments technical field of the present invention, and in particular to a kind of Orthopedic rod that multidirectional can provide angle compensation connects
Connect device.
Background technology
Deformity of spine refers to one of backbone or the bending of several sections 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, has a strong impact on heart and the breathing of infant
Function, influenceing 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 general 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, simultaneously by strong metal bar on post
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 section 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, because the original intention of connector design is reliably to obtain between rod and rod
Stable connection, its structure type is, on a tetragonal body, processes 2 parallel holes, lock-screw is machined with hole wall,
The head for two rods for needing to connect respectively penetrates the two holes to tail, then is compressed and locked with lock-screw, that is, completes connection, such as.
However, obvious drawback be present using connector treatment children's early onset deformity of spine between existing rod.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 bring high postoperative complication 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.One kind has been developed for this to 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
It is an object of the invention to provide a kind of orthopedic rod connector for being capable of multidirectional offer angle compensation.
The object of the present invention is achieved like this, including connector body and lock-screw, it is characterized in that：Described connection
Device 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, described connection
A side wall is provided with extension in device main body, and spherical pore is provided with the extension, 1# multi-directional balls are installed in the spherical pore,
Both are rotatably assorted, and Orthopedic rod is provided with the 1# multi-directional balls and penetrates hole and penetrates Kong Ping with the Orthopedic rod on connector body
OK, 2# multi-directional balls are set between described connector body and extension, and 2# multi-directional balls are located at spherical on connector body
In hole.
After two Orthopedic rods are connected using this connector, solve and insert the difficulty that long rod wears rod connection difficulty
Topic, 1# Orthopedic rods can be made 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 1# multi-directional balls can make 1# Orthopedic rods relative to 2# Orthopedic rods certain
Swung in angle, the setting of 2# multi-directional balls can be such that 2# Orthopedic rods are swung relative to 1# Orthopedic rods in certain angle, reduce
The constraint moved left and right to backbone, increases the pliability of backbone, therefore be significantly reduced because one end backbone is fixed two
The spontaneous fusion risk brought.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention；
Fig. 2 is Fig. 1 vertical view partial schematic sectional view；
In figure：1- connector bodies, 11- extensions, 2-1# multi-directional balls, 21-2# multi-directional balls, 3- lock-screws, 4-1# are rectified
Shape rod, 5-2# Orthopedic rods.
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 and lock-screw 3, and described connector body 1 is provided with
Orthopedic rod penetrates hole, and vertical Orthopedic rod penetrates hole and sets locking hole to coordinate with lock-screw 3, one on described connector body 1
Side wall is provided with extension 11, and spherical pore is provided with the extension 11,1# multi-directional balls 2 are installed in the spherical pore, both
It is rotatably assorted, Orthopedic rod is provided with the 1# multi-directional balls 2 and penetrates hole and penetrates Kong Ping with the Orthopedic rod on connector body 1
OK, 2# multi-directional balls 21 are set between described connector body 1 and extension 11, and 2# multi-directional balls 21 are located at connector body 1
On spherical pore in.
Pass through fixed axis connection between described extension 11 and connector body 1.
Described connector body 1 is square, cuboid or cylindrical structure.
Equal rounding when described connector body 1 is square or cuboid.
Described locking hole is at least provided with one.
Described connector body 1 is titanium alloy material.
Described 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, 1# multi-directional balls 2 and 2# multi-directional balls 21 can be same
When rotate or relatively rotate, drive that 1# Orthopedic rods rotate and/or 2# Orthopedic rods rotate, meet the needs of Orthopedic rod swing, increase
The big scope for swinging compensation, also increases the flexibility of swing.
