Abstract
The utility model discloses a can make orthopedic rod freely stretch out and draw back just takes angle compensation function's connector, including the connector main part, universal ball and locking screw, the connector main part be provided with orthopedic rod and penetrate the hole, perpendicular orthopedic rod penetrates the hole and sets up locking hole and locking screw cooperation, the connector main part on a lateral wall be provided with the extension, be provided with spherical pore on the extension, the universal ball of installation among the spherical pore, both normal running fit, be provided with on the universal ball orthopedic rod penetrate the hole and with the connector main part on orthopedic rod to penetrate the hole parallel. After adopting this connector to couple together two orthopedic rod, having solved and having put into the difficult problem that long rod wore stick connection difficulty, can make two sticks carry out longitudinal movement free relatively, when suitably controlling the deformity of spine, the backbone of induced deformity is vertically freely grown, and setting up of universal ball can make the relative swing of realization in certain angle of two sticks, reduces the restraint to removal about the backbone, increases the pliability of backbone.
Description
Technical field
This utility model medical apparatus and instruments technical field, is specifically related to a kind ofly can make Orthopedic rod free-extension and the adapter of band angle compensation function.
Background technology
Deformity of spine refers to that one of spinal column or several sections depart from the bending of midspinal line, usually with increase or the reduction of processus aboralis or prolapse in the rotation of vertebral body and sagittal plane.It is a kind of deformity of spine of three-dimensional, and its incidence rate is about about 0.5-2% in teenager, can caused by various diseases.When skoliosis angle is excessive, or when presenting obvious progressive trend, just need to consider operative treatment; Otherwise serious and stiff deformity of spine can be developed into gradually, have a strong impact on heart and the respiratory function of infant, affect spinal function and cause paralysis, even life-threatening.The main purpose of operative treatment prevents deformity progress, recovery spine balance; Correction deformity as much as possible.At present deformity of spine is carried out to the ultimate principle of surgical orthopaedic, namely based on the metal grappling utensil (as pedicle screw, hook, steel wire) being fixed on different parts on spinal column, connected by strong metal bar, apply orthopedic force by instrument carries out orthopedic simultaneously, and forces to be fixed spinal column and to merge.
Clinically, in order to strengthen the fixing intensity of spinal column, or it is fixing to carry out prolongation at the sections that spinal column has been fixed, and in the growing rod treatment of children's's early onset deformity of spine, usually need to use coupling to carry out connecting between rod with rod, the coupling the most often used is at present adapter between rod, to be reliably to obtain between rod with rod stable connects for the original intention of coupling design, its version is, on a tetragonal body, process 2 parallel holes, hole wall is processed with lock-screw, two the excellent heads needing to connect are penetrated this two holes respectively to tail, locking is compressed again with lock-screw, namely connection is completed, as.
But, utilize coupling treatment children's early onset deformity of spine between existing rod to there is obvious drawback.On the one hand, row operation is all needed once every regular time (general 6-9 month), to appear coupling, the one-sided trip bolt unclamping it and connect with rod, and use and strut strength and make children's's spinal column obtain limited prolongation, object is the growth headspace for spinal column; Thus repeatedly for several times, after even tens of times, high postoperative complication must be brought to operation.On the other hand, by complete locked fixing between Orthopedic rod, Orthopedic rod cannot realize free-extension, limits spinal column free growth, and does not meet the principle of current biologic treatment.Developed one for this reason and can allow Orthopedic rod free-extension, the multipurpose connector being simultaneously with pendulum angle to compensate has very major and immediate significance.
Utility model content
The purpose of this utility model is to provide and a kind ofly can makes Orthopedic rod free-extension and the adapter of band angle compensation function.
The purpose of this utility model realizes like this, comprise connector body, multi-directional ball and lock-screw, described connector body is provided with Orthopedic rod and penetrates hole, vertical Orthopedic rod penetrates hole and arranges locking hole and coordinate with lock-screw, on described connector body, a sidewall is provided with extension, described extension is provided with spherical pore, in described spherical pore, multi-directional ball is installed, both are rotatably assorted, and described multi-directional ball are provided with Orthopedic rod and penetrate hole and to penetrate hole parallel with the Orthopedic rod on connector body.
After adopting this adapter to be coupled together by two Orthopedic rods, solve and insert the difficult problem that rod connection difficulty worn by long rod, 1# Orthopedic rod can be made to carry out freely vertically moving relative to 2# Orthopedic rod, while suitably controlling deformity of spine, the longitudinal free growth of spinal column of induction deformity, avoid the constraint to spinal growth, and avoid repeatedly repeatedly to strut and extend operation and spinal cord stretching for the threat of spinal function, arranging of multi-directional ball can make 1# Orthopedic rod swing in certain angle relative to 2# Orthopedic rod, decrease the constraint that spinal column is moved left and right, increase the pliability of spinal column, therefore also significantly reduce because spinal column two spontaneities of bringing that are fixed in one end merge risks.

Fig. 2 is the schematic top plan view of Fig. 1;
In figure: 1-connector body, 11-extension, 2-multi-directional ball, 3-lock-screw, 4-1# Orthopedic rod, 5-2# Orthopedic rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but limited this utility model never in any form, based on any conversion that this utility model training centre is done, all falls into this utility model protection domain.
As shown in Figure 1 and 2, this utility model comprises connector body 1, multi-directional ball 2 and lock-screw 3, described connector body 1 is provided with Orthopedic rod and penetrates hole, vertical Orthopedic rod penetrates hole and arranges locking hole and coordinate with lock-screw 3, on described connector body 1, a sidewall is provided with extension 11, described extension 11 is provided with spherical pore, multi-directional ball 2 is installed in described spherical pore, both are rotatably assorted, and described multi-directional ball 2 are provided with Orthopedic rod and penetrate hole and to penetrate hole parallel with the Orthopedic rod on connector body 1.Orthopedic rod penetrates the diameter in hole according to the difference of Orthopedic rod diameter, has different specifications.Penetrate another root Orthopedic rod of multi-directional ball 2, can slide in the hole of multi-directional ball 2, also with the rotation of multi-directional ball 2, certain swing can be done.
Described connector body 1 is square, cuboid or cylindrical structure.
Described connector body 1 be square or cuboid time equal rounding.
Described extension 11 is integral type structure with described connector body 1.
