Abstract
The utility model relates to medical apparatus for orthopaedic surgery, in particular to an adjustable spiral rod which comprises a first connecting rod and a second connecting rod, wherein one end of the first connecting rod and one end of the second connecting rod are respectively inserted in pediculus arcus vertebrae screw grooves, the first connecting rod and the second connecting rod are fixedly connected with pediculus arcus vertebrae screws, and the inner end surface of the other end of the first connecting rod is in tooth-like meshing with the inner end surface of the other end of the second connecting rod. The adjustable spiral rod has the benefits of convenient operation, simple adjustment method, firm connection and no looseness when in use.
Description
Technical field
This utility model relates to the bone surgery medical apparatus, in particular for preventing that spondylolishesis, spinal fracture, deformity of spine from correcting and the adjustable spinal rod of internal fixation.
Background technology
Be used for spondylolishesis at present, spinal fracture, the spinal column degeneration, the spinal rod of internal fixation systems such as deformity of spine rectification, it is curved to need to use special-purpose curved rod pincers in advance spinal rod to be broken off with the fingers and thumb, then spinal column is being corrected, and spinal rod operates very loaded down with trivial details like this, spinal rod is easy to be broken off with the fingers and thumb disconnected, and whole adjustment process is very complicated.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the shortcoming and defect of above-mentioned existence, provide a kind of simple operation, adjust simple adjustable spinal rod.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of adjustable spinal rod, have first pitman and second pitman, insert respectively in the pedicle nail groove at an end of first pitman and an end of second pitman, first pitman, second pitman are fixedlyed connected with pedicle nail, are the dentation engagement at the inner face of the other end of the inner face of the other end of first pitman and second pitman.
In order better to realize the adjustable function of spinal rod, the dentation engagement is the zigzag engagement, and first pitman, second pitman are fixedlyed connected by plug screw with pedicle nail, and the other end of first pitman is connected by housing screw with the other end of second pitman.
The beneficial effects of the utility model are, this utility model in use, simple operation, method of adjustment are simple, and are connected firmly, and can not produce loosening.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a side view of the present utility model.
Among the figure: 1. first pitman, 2. second pitman, 3. pedicle nail, 4. housing screw.
The specific embodiment
With preferred embodiment this utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the sketch map of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with this utility model.
Adjustable spinal rod as depicted in figs. 1 and 2, have first pitman 1 and second pitman 2, insert respectively in the pedicle nail groove at an end of first pitman 1 and an end of second pitman 2, first pitman 1, second pitman 2 are fixedlyed connected with pedicle nail 3, are the dentation engagement at the inner face of the other end of the inner face of an end of first pitman 1 and second pitman 2.
The dentation engagement is the zigzag engagement, and first pitman 1, second pitman 2 are fixedlyed connected by plug screw with pedicle nail, and the other end of first pitman 1 is connected by housing screw 4 with the other end of second pitman 2.
Below using method of the present utility model is done further introduction:
This utility model in use, unscrew housing screw earlier, first pitman 1 and second pitman 2 are turned to the angle that the rectification spinal column needs, and the pedicle nail 3 of packing into is after rectification puts in place, screw housing screw 4, first pitman 1 and 2 liang of flank of tooth of second pitman are meshing with each other form a fixed angle, owing to be the dentation engagement, so first pitman 1 and second pitman 2 can not become flexible, the reuse specific purpose tool resets damaged part, screws plug screw at last.
The end face tooth matching angle of first pitman 1 and second pitman 2 can form multi-angle and connect according to actual needs, and reuse housing screw 4 compresses and makes whole assembly be not easy to become flexible at the adjustment connection procedure, and operating process is simple and convenient.
