Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of atlas sets nail multifunctional guide device.
Background technique
Atlas (Atlas) is derived from the smooth huge refreshing Atlas of Thailand for bearing the earth in Greek mythology, refers to higher vertebrate
Atlas.Atlas circularizes, without centrum, spinous process and processus articular superior, and by anterior arch, cantle and two lateral mass (lateral
Mass it) constitutes.Atlas screw has been widely used in fracture, spinal canal stenosis and tumor of spine.Atlas, which sets nail method, to be had very much, and art
Middle navigation is most accurately.But navigation system is at high price, it is difficult to apply in a wider context in a short time.Base doctor is because of condition
Limitation, in art often by rule of thumb, the merging of feel row atlas screw, position is often difficult to control, or even can wear out atlas,
Incidence is 20~30%.It is improper or accidentally set that we in basic hospital can usually encounter atlas nail implantation, causes the reduction of the fracture
It is bad, fixed unstable, or even many such as atlas screws occur and wear out atlas, centrum, damage blood vessel, spinal cord, nerve root etc.
Complication.Thus the atlas of low cost sets nail guider and needs widely to popularize.
Summary of the invention
The purpose of the present invention is to solve disadvantage existing in the prior art, and to set nail multi-functional for a kind of atlas proposed
Guider.
To achieve the above object, present invention employs following technical solutions:
A kind of atlas sets nail multifunctional guide device, including bottom plate, and the left side bottom end of the bottom plate is equipped with shoulder deck, described
The top of bottom plate is equipped with sliding slot, and connecting plate is slidably connected in sliding slot, and the interior side of the sliding slot is solid by rolling bearing
Dingan County is equipped with gear, and the shaft right end of gear is fixedly connected with adjusting turntable, the bottom end side of the connecting plate through bottom plate
Equipped with bar shaped tooth, and bar shaped tooth engages connection with gear, and the upper end of the connecting plate is equipped with screw directed access body, the connection
The left side top of plate is equipped with head supporting plate.
Preferably, the bottom plate and connecting plate are camber, and position is equipped with opening among the bottom of connecting plate.
Preferably, the shoulder deck is the curved surface chamfering structure that Open Side Down, and head supporting plate is the song of opening upwards
Face camber.
Preferably, the shoulder deck and head supporting plate are symmetrically arranged with two groups, and the table of shoulder deck and head supporting plate
Surface cover rubber sleeve.
Preferably, the surface of the gear and bar shaped tooth is coated with aluminum oxide wear layer.
Preferably, the screw directed access body is at least provided with three groups.
Preferably, the upper end that the top of the bottom plate is located at gear is equipped with ratchet.
Technical effect and advantage of the invention: a kind of atlas proposed by the present invention sets nail multifunctional guide device, with existing skill
Art is compared, can be convenient for fixed neck by shoulder deck and head supporting plate, and error occurs in neck shaking when preventing from setting nail,
Bottom plate and connecting plate can adjust turntable by rotation simultaneously makes gear and bar shaped tooth generate displacement, consequently facilitating adjusting shoulder card
The distance between seat and head supporting plate, because atlas is the atlas of higher vertebrate, thus the spiral shell on connecting plate top
It follows closely directed access body to adjust to the position of corresponding atlas, screw directed access body can be in order to difference at least provided with three groups
Position carries out setting nail, which designs advantages of simple, and easy to operate, convenient for adjusting, manufacturing cost is low, safety and stability, protects
Card atlas sets the effect of nail, full-featured, applied widely, is conducive to popularize.
