Abstract
The utility model discloses a kind of atlas and axis pedicle screw guider, a kind of atlas and axis pedicle screw guider, comprise director module, described director module bottom is provided with the arc port dug out according to human cervical spine structure, and the two ends, left and right of described director module are arranged with the first pilot hole and the second pilot hole.This atlas and axis pedicle screw guider, director module is placed on instability place by arc port structure, first pilot hole and the second pilot hole are used in inside cervical operation, doctor's guide pin, be applicable to the neck bone shelf structure of most of human body, former cervical operation is all the experience by doctor, does not have this device in the past, be easy to cause operative failure, atlas and axis pedicle screw guider substantially increases the success rate of operation.
Description
Technical field
This utility model relates to technical field of medical instruments, is specially a kind of atlas and axis pedicle screw guider.
Background technology
Atlas and axis is the high-order cervical vertebra of human body, and anatomical structure is special, neighbouring relationship is complicated, and intraspinal tube comprises the breathing heart beating maincenter of human body, and canalis spinalis side is the vertebral artery of head with blood.If nail is planted in operation, position is slightly improper, just can cause the damage of breathing the vital tissue structure such as heart beating maincenter or vertebral artery; The lighter's massive hemorrhage threat to life or high paraplegia rely on respirator existence, and severe one occurs that respiratoring palpitating suddenly stopping patient dies instantly.Because ontogeny there are differences, further increase the risk of this position operation, this position operation be regarded as always perform the operation high risk zone, operating difficulty is very big, risk is high, domestic only have minority large hospital can carry out this region at present operation and operative failure case is unrare.
Summary of the invention
The purpose of this utility model is to provide a kind of atlas and axis pedicle screw guider, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of atlas and axis pedicle screw guider, comprise director module, described director module bottom is provided with the arc port dug out according to human cervical spine structure, and the two ends, left and right of described director module are arranged with the first pilot hole and the second pilot hole.
Preferably, described first pilot hole is identical with the aperture of the second pilot hole.
Compared with prior art, the beneficial effects of the utility model are: this atlas and axis pedicle screw guider, director module is placed on instability place by arc port structure, first pilot hole and the second pilot hole are used in inside cervical operation, doctor's guide pin, are applicable to the neck bone shelf structure of most of human body, cervical operation is in the past all the experience by doctor, do not have this device in the past, and be easy to cause operative failure, atlas and axis pedicle screw guider substantially increases the success rate of operation.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1-director module; 2-first pilot hole; 3-second pilot hole; 4-arc port.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of atlas and axis pedicle screw guider, comprise director module 1, director module 1 bottom is provided with the arc port 4 dug out according to the instability of human body, it is identical with the aperture of the second pilot hole 3 with the second pilot hole 3, first pilot hole 2 that the two ends, left and right of director module 1 are arranged with the first pilot hole 2.
Operation principle: director module 1 is placed on instability place by arc port 4 structure, first pilot hole 2 and the second pilot hole 3 are used in inside cervical operation, intert as doctor's guide pin, be applicable to the neck bone shelf structure of most of human body, cervical operation is in the past all the experience by doctor, easily cause operative failure, atlas and axis pedicle screw guider substantially increases the success rate of operation.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
