Description
Technical field
The invention belongs to orthopedic tool technical field, the kyphosis of a kind of adjustable angle is rectified
Shape rod.
Background technology
Spinal anterior approach is a kind of common deformity of spine, the ridge that especially ankylosing spondylitis and hemivertebra etc. cause
Post kyphosis deformity, needs Osteotomy And Orthomorphia more, but during operation, due to convexity number continuous after in orthopaedic procedures
Change needs constantly row curved rod technology, and the most repeatedly curved rod not only can reduce the fatigue resistance of Orthopedic rod, and whole process
Operate considerably complicated, waste time and energy, it is therefore desirable to existing technology is improved.
Summary of the invention
In view of this, present invention is primarily targeted at the kyphosis Orthopedic rod of a kind of adjustable angle is provided.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
The embodiment of the present invention provides the kyphosis Orthopedic rod of a kind of adjustable angle, and this kyphosis Orthopedic rod includes that first rectifys
Shape rod, the second Orthopedic rod, described first Orthopedic rod, the end of the second Orthopedic rod are socket arrangement；Described first Orthopedic rod,
Two Orthopedic rods arrange dentation in the socket arrangement of any one, arranges in another socket arrangement and join with dentation
The groove closed；Described first Orthopedic rod, the socket arrangement of the second Orthopedic rod connect by screw and nut is fixing.
In such scheme, described first Orthopedic rod and second Orthopedic rod diameter near socket arrangement one end are more than away from ball
The diameter of nest structure one end.
In such scheme, described dentation is arranged in the socket arrangement of first Orthopedic rod one end, described second orthopedic
The groove coordinated with dentation is set in the socket arrangement of rod.
Compared with prior art, beneficial effects of the present invention:
The present invention can reduce the number of times of curved rod, need not use preset rod, is substantially reduced the complexity of operating time and operation,
Operation is made to become simple, quickly；Socket arrangement internal gear coincide add Outer screw, nut fixing, the firmest, reduce
The risk loosened.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention provides the kyphosis Orthopedic rod of a kind of adjustable angle, as shown in Figure 1, 2, 3, after this spinal column
Convex Orthopedic rod includes that first Orthopedic rod the 1, second Orthopedic rod 2, the end of described first Orthopedic rod the 1, second Orthopedic rod 2 are ball-and-socket
Structure 5；Described first Orthopedic rod the 1, second Orthopedic rod 2 arranges dentation 4 in the socket arrangement 5 of any one, another
Socket arrangement 5 in the groove coordinated with dentation 4 is set, by dentation 4 and the cooperation of groove so that first is orthopedic
Rod the 1, second Orthopedic rod 2 is fixed, and inside is hollow structure；The socket arrangement 5 of described first Orthopedic rod the 1, second Orthopedic rod 2
By screw 3 and the fixing connection of nut 6, formation is firmly fixed, and should not loosen.
Described first Orthopedic rod 1 and second Orthopedic rod 2 diameter near socket arrangement 5 one end are more than away from socket arrangement 5
The diameter of one end, so, enough increases the intensity of Orthopedic rod, prevents the generation of disconnected rod；Such as: described first Orthopedic rod 1, second is rectified
The pole of a diameter of 5.5mm or 6.0mm of rod of shape rod 2 medium nest structure 5 far-ends, proximal diameter is 8mm.
Described dentation 4 is arranged in the socket arrangement 5 of first Orthopedic rod 1 one end, the ball-and-socket of described second Orthopedic rod 2
The groove coordinated with dentation 4 is set in structure 5.
The work process of invention:
First have to tighten the stud 7 connecting two Orthopedic rods, rod be bent in advance the radian state needed, then stud 7 is unscrewed,
So, two Orthopedic rods just can adjust angle, is fixed to above pedicle screw by two Orthopedic rods, socket arrangement 5 place
Position, just after the most serious convex position needing orthomorphia, continue loosen screw 3, tighten after forming suitable angle
Screw 3 is fixed.Along with the change of rear convexity number during surgical orthopaedic, constantly sending and tighten screw 3, operation is last
After the dentation 4 of two Orthopedic rod socket arrangement 5 and groove are perfectly coincide, screw 3 and nut 6 are tightened fixing.
The above, only presently preferred embodiments of the present invention, it is not intended to limit protection scope of the present invention.
