Abstract
This utility model relates to a kind of medical apparatus and instruments for the treatment of fracture of cervical vertebra, and the way of escape being applicable to Study of Atlas Fracture by Finite resets and fixes.A kind of way of escape Study of Atlas Fracture by Finite reduction fixation system is made up of uni-axial screws (1), pitman (2), sleeve (3) and pressurized clamp (4); Uni-axial screws (1) is followed closely (5), plug screw (6) and long-armed adapter (7) by stigma and is formed; Pitman (2) is pre-bent to the physiologic radian close to arch of posterior atlas; Sleeve (3) bottom diameter is identical with long-armed adapter (7) external diameter, and the less internal diameter in upper end can prevent sleeve from crossing multiple location and enter human body, reduces damage, outer knurled, increases frictional force; Pressurized clamp (4) left and right handle rotates centered by axial screw, plays the effect of pressurization, blocks arc-shaped rack when stop button is pressed, reach the object of pressurized clamp stop when left and right handle is filled the span of a man's arms.Implant uni-axial screws during operation, be placed in by pitman in long-armed adapter, cover upper bush, pressurized clamp of filling the span of a man's arms makes the reduction of the fracture.
Description
Technical field
This utility model relates to the way of escape reduction fixation device that a kind of medical apparatus and instruments for the treatment of fracture of cervical vertebra, particularly atlas (atlas) are fractured.
Background technology
For unstable Study of Atlas Fracture by Finite, adopt front road through oropharynx reduction fixation, comparatively satisfaction is fixed in the reduction of the fracture, but operation technique is difficult, complicated, and frequent concurrent infection of incisional wound, and internal fixtion exposes, and causes great risk and misery to patient.Existing way of escape reduction fixation system is difficult to the good reset obtaining Study of Atlas Fracture by Finite, especially anterior arch of atlas fracture, and often need to carry out atlanto―axial fusion, postoperative patient incidence activity critical constraints, brings serious inconvenience to minimal invasive treatment.
Summary of the invention
The purpose of this utility model is: for prior art Problems existing, the invention provides a kind of way of escape Study of Atlas Fracture by Finite reduction fixation system, better achieves the reduction of the fracture, avoid the high infection rate of anterior approach.
The technical solution of the utility model is as follows:
A kind of way of escape Study of Atlas Fracture by Finite reduction fixation system is made up of uni-axial screws 1, pitman 2, sleeve 3 and pressurized clamp 4, it is characterized in that: uni-axial screws 1 is made up of stigma nail 5, plug screw 6 and long-armed adapter 7.
Uni-axial screws 1: the rivet nut of stigma nail 5 is with half-thread, columnar head is with interior six square grooves and step-like convex, step-like convex lower end is that arc can realize the rounding off with columnar head, plug screw 6 outside is regular screw thread, inner with one or six square grooves, have V-type groove in the middle part of long-armed adapter 7, the step-like convex that bottom has step-like hole and stigma to follow closely 5 matches, and makes stigma follow closely 5 and is connected with long-armed adapter 7.
Pitman 2: be pre-bent to arc (physiologic radian close to arch of posterior atlas).
Sleeve 3: bottom diameter is identical with long-armed adapter 7 external diameter, to hold on long-armed adapter 7, facilitates operation technique, the less internal diameter in upper end can prevent sleeve from crossing multiple location and enter human body, reduces damage, outer knurled, increases frictional force, plays anti-skidding effect.
Pressurized clamp 4: be made up of left and right handle, axial screw, pivot pin nail, shifting shaft, flat spring, pan head screw, arc-shaped rack and stop button, left and right handle rotates centered by axial screw, the effect of pressurization is played when left and right handle is filled the span of a man's arms, stop button blocks arc-shaped rack when pressing, and reaches the object of pressurized clamp stop.
This utility model has the following advantages:
This utility model adopts less invasive techniques, and operative incision is little, reduces the stimulation to skin, makes operation technique convenient and is more conducive to the fixing of the reset of way of escape Study of Atlas Fracture by Finite, being easy to patients ' recovery.
This utility model can overcome the problem that existing way of escape reduction fixation system carries out Atlantoaxial fusion postoperative patient person incidence activity critical constraints, brings convenience to minimal invasive treatment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
1. the cantle through tuberculum posterius atlantis both sides 18-20mm implants uni-axial screws respectively;
2. be pre-bent to arc (physiologic radian close to arch of posterior atlas) through pitman, be placed in the long-armed adapter of above-mentioned uni-axial screws afterbody;
3. two pieces of sleeves are placed on above-mentioned two pieces of long-armed adapters of uni-axial screws afterbody;
4. pressurized clamp pressurization of filling the span of a man's arms makes two screws close to each other, simultaneously assistant by above-mentioned two pieces of sleeves with screw and pitman joint for fulcrum, do separation rotary motion, impel Study of Atlas Fracture by Finite to reset;
5. lock plug screw;
6. fracture long-armed for screw with disconnected arm device, perspective understands reset case.
