The embodiment it should be understood that
The outer peripheral surface of the lifting fixed body 1 is equipped with screw occlusion section 11, convenient for forming fixation with centrum to be pulled,
It avoids falling off during lifting.
The junction of the lifting fixed body 1 and stroke control volume 2 is equipped with connector 6, and the design of connector 6 is so that mention
It draws connection between fixed body 1 and stroke control volume 2 reliably, convenient for the transitional function of transmission force, to avoid force localization, and causes
Damage.
The radial dimension of the screw occlusion section 11 is gradually increased from distal end to proximal end, which makes active force
Distribution is conducive to establish stable mechanical environment in the form of asymptotic distribuion.
The stroke control volume 2 is equipped with external screw thread 21, is equipped with internal screw thread in the inside of flexible handle 4 accordingly, and
When internal screw thread and external screw thread 21 cooperate, relatively moves, that is, using between flexible handle 4 and stroke control volume 2
Under state, when precession flexible handle 4 is to close to the movement of lifting 1 end of fixed body, skidding process control body 2 is displaced outwardly, thus band
The dynamic lifting outside stress of fixed body 1 lifting, realizes the lifting function of centrum, ingenious in design.
External screw thread 21 on the stroke control volume 2 is axially distributed, in this way, whenever flexible handle 4 is along stroke
When the axial precession certain distance of control volume 2, then it can trigger stroke control volume 2 and lifting fixed body 1 lifts centainly outward
Distance is that correspondingly, to realize, realization is stable between the two, controllable, slow centrum Forward.
It between the stroke control volume 2 and flexible handle 4 is matched by internal screw thread and external screw thread 21, stroke control
Generate relative motion between body 2 and flexible handle 4, and stroke control volume 2 it is coaxial with the direction of motion of flexible handle 4 to, in this way,
It can ensure that 2 Impact direction of stroke control volume is stablized, under use state, lifting tool is planted using the hole in titanium plate in center
Enter centrum, can be achieved with vertically lifting.
The connecting rod 3 is smooth shaft, and connecting rod 3 provides movable model convenient for socket flexible handle 4, for flexible handle 4
It encloses, convenient for can be adjusted as needed.
The outer peripheral surface of the flexible handle 4 and fixed handle 5 is all provided with equipped with inner concave 7.The design of inner concave 7 is convenient for increasing
Add frictional force, manpower is facilitated to operate.
It is removably to be fixedly connected with mode between the fixed handle 5 and connecting rod 3, which is convenient for live
Fixed handle 4 is socketed in connecting rod 3.
The flexible handle 4 and fixed handle 5 is column structure, and the design method is handling good, as a kind of excellent
Choosing, can be designed as flat structure for fixed handle 5, to meet manipulation demand.
A kind of application method of lifting tool for cervical vertebral body Forward fusion of the utility model is: lifting tool
Using the hole in titanium plate, it is implanted into centrum in center, and block the controllable Forward that titanium plate realizes centrum using casing.
A kind of lifting tool for cervical vertebral body Forward fusion of the utility model, it is controllable to can be realized centrum,
The lifting vertical, stability is good can be used as a kind of new tool of centrum lifting, have wide answer in clinical promotion and application
Use prospect；The outer peripheral surface of lifting fixed body 1 is equipped with screw occlusion section 11 and avoids mentioning convenient for forming fixation with centrum to be pulled
It falls off during drawing；Stroke control volume 2 is equipped with external screw thread 21, is equipped with internal screw thread in the inside of flexible handle 4 accordingly, and work as
It when internal screw thread and external screw thread 21 cooperate, is relatively moved between flexible handle 4 and stroke control volume 2, that is, is using shape
Under state, when precession flexible handle 4 is to close to the movement of lifting 1 end of fixed body, skidding process control body 2 is displaced outwardly, to drive
The lifting of the outside stress of fixed body 1 is lifted, the lifting function of centrum is realized, it is ingenious in design；External screw thread 21 on stroke control volume 2
It is axially distributed, in this way, can then trigger row whenever axial precession certain distance of the flexible handle 4 along stroke control volume 2
Process control body 2 and lifting fixed body 1 lift a certain distance outward, are correspondingly, to realize reality between the two
It is now stable, controllable, slow centrum Forward；It is by internal screw thread and external screw thread between stroke control volume 2 and flexible handle 4
21 match, and relative motion, and the fortune of stroke control volume 2 and flexible handle 4 are generated between stroke control volume 2 and flexible handle 4
Dynamic direction is coaxial in such manner, it is possible to ensure that 2 Impact direction of stroke control volume is stablized, under use state, lifting tool utilizes titanium plate
On hole, in center be implanted into centrum, can be achieved with vertically lifting.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvement and supplement under the premise of not departing from the utility model method, these are improved and supplement
Also it should be regarded as the protection scope of the utility model.
