Abstract
The utility model relates to a medical apparatus, in particular to a vertebral pedicle screw tail wing fracturer, which comprises a fracturer body. A slide groove which is arranged on the fracturer body is provided with a slide screw. The upper part and the lower part of the slide screw are provided with two wing clamping tongues which are connected with the inner side of the fracturer body. One side of the slide screw is provided with a nut. The fracturer body is provided with an operation handle and a tail wing looping. Because the utility model is masterly provided with the wing clamping tongues and the tail wing looping and uses a support point in the fracturer, in the use process, a tail wing can not be damaged easily and can be controlled conveniently, surrounding tissues can not be damaged, the operation is convenient and the practicality is strong.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of pedicle screw empennage fracturer.
Background technology
At present, the pedicle screw of great majority use all has empennage clinically, and empennage is promptly ineffective after inserting pedicle of vertebral arch at screw, load onto connecting rod and screwing in the tail medicated cap.In order to reduce the screw incisura, the empennage taking-up that need fracture.Most of hospital operating room fractures with vice or clamping plate pincers, and these tool holding empennage excuse portions are thick, inconvenient operation, and power thrusts is wayward, and support point is difficult for holding, and causes the loosening and surrounding tissue damage of pedicle screw easily.
Summary of the invention
In order to address the above problem, this utility model provides the relative advantages of simple of a kind of structure, easy to operate, practical pedicle screw empennage fracturer.
To achieve these goals, this utility model is mainly solved by the following technical programs:
A kind of pedicle screw empennage fracturer comprises the fracturer body, on the chute that described fracturer body is provided with sliding screw is housed, two folder wing tongues that the having up and down of sliding screw is connected fracturer body inboard, and a side of sliding screw is provided with nut; The fracturer body is provided with operating grip and empennage running-on.
Owing in this utility model, be provided with folder wing tongue and empennage running-on cleverly, used support point in the fracturer, make in use not fragile empennage, hold control easily, can not cause damage to surrounding tissue, and easy to operate and Practical Performance is strong.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing 1-3, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of pedicle screw empennage fracturer comprises the fracturer body 1 of inner hollow out.One end of fracturer body 1 is provided with empennage running-on 7, and the other end is provided with handle 6.Be provided with two folder wing tongues 4 in the fracturer body 1.The position of two folder wing tongues 4 is corresponding.
The chute 2 that the both sides of disconnected device body 1 are provided with is equipped with the sliding screw 3 that is complementary with described chute 2 on the chute 2, sliding screw 3 is in the middle of two folder wing tongues 4.One end of sliding screw 3 is provided with nut 5, prevents that sliding screw 3 breaks away from chute 2.
When in use, sliding screw 3 separates two folder wing tongues 4 as for empennage running-on 7 one sides.Empennage running-on 7 is inserted in fully the folding line place of pedicle of vertebral arch arc empennage, sliding screw 3 can move to handle 6 directions along chute 2, folder wing tongue 4 is automatically with the empennage clamping, with operating grip to the doubling direction empennage that firmly fractures, the empennage that fractures is stayed in the fracturer body 1, sliding screw 3 is promoted to empennage running-on 7 directions, can take out the empennage that fractures.
