Abstract
The utility model discloses a but angle of adjustment's kyphosis orthopedic rod, this kyphosis orthopedic rod include an orthopedic rod, the 2nd orthopedic rod, an orthopedic rod, the 2nd orthopedic rod's tip is the ball socket structure, one the arbitrary structural tooth -shaped protrusion that sets up of ball socket among an orthopedic rod, the 2nd orthopedic rod, set up in another the ball socket structure with tooth -shaped protrusion complex recess, screw and nut fixed joint are passed through to an orthopedic rod, the 2nd orthopedic rod's ball socket structure. The utility model discloses can reduce the number of times of curved stick, need not use and preset the stick, the complexity of greatly reduced operation time and operation makes the operation become simple, fast, the inside gear of ball socket structure coincide and adds the fixed of outside screw, nut, and more firm reduces not hard up risk.
Description
Technical field
The utility model belongs to orthopedic tool technical field, after specifically a kind of backbone of adjustable angle
Convex Orthopedic rod.
Background technology
Spinal anterior approach is a kind of common deformity of spine, the ridge that especially ankylosing spondylitis and hemivertebra etc. are caused
Post kyphosis deformity, needs Osteotomy And Orthomorphia more, but during operation, due to after in orthopaedic procedures convexity number it is continuous
Change needs the constantly row curved rod technology, so multiple curved rod not only to reduce the fatigue resistance of Orthopedic rod, and whole process
Operate considerably complicated, waste time and energy, it is therefore desirable to which existing technology is improved.
Utility model content
In view of this, main purpose of the present utility model is the humpback Orthopedic rod for providing a kind of adjustable angle.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
The utility model embodiment provides a kind of humpback Orthopedic rod of adjustable angle, the humpback Orthopedic rod bag
The first Orthopedic rod, the second Orthopedic rod are included, first Orthopedic rod, the end of the second Orthopedic rod are socket arrangement；Described first
Dentation is set in the socket arrangement of any one in Orthopedic rod, the second Orthopedic rod, set in another socket arrangement with
The groove that dentation coordinates；First Orthopedic rod, the socket arrangement of the second Orthopedic rod are fixedly connected by screw and nut.
In such scheme, first Orthopedic rod and the second Orthopedic rod are near socket arrangement one end with diameter greater than away from ball
The diameter of nest structure one end.
In such scheme, the dentation is arranged in the socket arrangement of first Orthopedic rod one end, and described second is orthopedic
The groove coordinated with dentation is set in the socket arrangement of rod.
Compared with prior art, the beneficial effects of the utility model：
The utility model can reduce the number of times of curved rod, without using preset rod, substantially reduce operating time with operation
Complexity, makes operation become simple, quickly；Socket arrangement internal gear coincide plus Outer screw, the fixation of nut, more
It is firm, reduce the risk for loosening.
Brief description of the drawings

Fig. 2 is side view of the present utility model,
Fig. 3 is internal structural map of the present utility model.
The Orthopedic rods of 1- first, the Orthopedic rods of 2- second, 3- screws, 4- detent projections, 5- socket arrangements, 6- nuts in figure.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
The utility model embodiment provides a kind of humpback Orthopedic rod of adjustable angle, as shown in Figure 1, 2, 3, the ridge
Convex Orthopedic rod includes the first Orthopedic rod 1, the second Orthopedic rod 2 after post, and first Orthopedic rod 1, the end of the second Orthopedic rod 2 are
Socket arrangement 5；Dentation 4 is set in first Orthopedic rod 1, the second Orthopedic rod 2 in the socket arrangement 5 of any one, separately
The groove coordinated with dentation 4 is set in the socket arrangement 5 of, by the cooperation of dentation 4 and groove so that first
Orthopedic rod 1, the second Orthopedic rod 2 are fixed, and internal is hollow structure；The ball-and-socket of first Orthopedic rod 1, the second Orthopedic rod 2
Structure 5 is fixedly connected by screw 3 with nut 6, and formation is firmly fixed, and should not be loosened.
The Orthopedic rod 2 of first Orthopedic rod 1 and second is near the one end of socket arrangement 5 with diameter greater 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；For example：First Orthopedic rod 1, second is rectified
The pole of rod a diameter of 5.5mm or 6.0mm of the distal end of 2 medium nest structure of shape rod 5, proximal diameter is 8mm.
The dentation 4 is arranged in the socket arrangement 5 of the one end of the first Orthopedic rod 1, the ball-and-socket of second Orthopedic rod 2
The groove coordinated with dentation 4 is set in structure 5.
The course of work of utility model：
First have to that two studs of Orthopedic rod 7 will be connected and tighten, rod is bent to the radian state of needs in advance, then by stud 7
Unscrew, so, two Orthopedic rods just can adjustment angle, two Orthopedic rods are fixed to above pedicle screw, socket arrangement 5
The position of orthomorphia, continues to loosen screw 3, after forming suitable angle the need for the position at place, exactly rear convex most serious
Screw 3 is tightened to be fixed.With the change of rear convexity number during surgical orthopaedic, screw 3 is constantly sent and tightened, perform the operation
Screw 3 and nut 6 are tightened into fixation after finally two dentations of Orthopedic rod socket arrangement 54 and groove perfectly coincide.
The above, preferred embodiment only of the present utility model is not intended to limit protection of the present utility model
Scope.
