Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is implemented
The component of example can be arranged and be designed with a variety of different configurations.
Therefore, the detailed description of disclosed the embodiment of the present invention in the accompanying drawings is not intended to limit below claimed
The scope of the present invention, but be merely representative of selected embodiment of the invention.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without creative efforts belongs to the model that the present invention protects
It encloses.
The present embodiment discloses a kind of cone nut nail and sets 120 devices of nail.Device through this embodiment can be in filling bone water
The cone nut of mud waits for that nail sets setting for position progress high-stability and follows closely 120 operations.
Referring to FIG. 1, the device of the present embodiment is matched including nail set 110 and with set 110 is followed closely to set nail 120.
Nail set 110 has a perforative mesoporous, mesoporous have internal screw thread for set nail 120 and be threadedly coupled.Mesoporous exists simultaneously
Length direction offers discharge groove 112, and bone cement is discharged during screwing in mesoporous for setting nail 120.The lower part of nail set 110
Bifurcated is two bulges 131.Each bulge 131 has screw thread blade respectively.
So nail set 110 of the present embodiment is wait set 120 positions of nail, can be with by the force turn-knob that medical staff is downward
Nail set 110 is screwed in bone cement；Simultaneously as helical blade 111 can be generated in rotary course along nail 110 length directions of set
Active force, enable nail set 110 faster, more laborsaving screw in the bone cement of the ot-yet-hardened wait set 120 positions of nail.
The nail 120 of setting of the present embodiment has the external screw thread 121 cooperated with inner threaded surface.It is fixed on the head for setting nail 120
It is treated after setting 120 operations of nail and sets the nail disk 122 that 120 positions of nail are completely covered
Through the above scheme, the present embodiment provides it is a kind of using above-mentioned cone nut nail set nail 120 devices set nail 120 operations
Method is specifically pouring into bone cement wait set 120 positions of nail；It not being solidified completely still in bone cement, i.e., bone cement has plastomer shape,
It is in the cohesive soil of plastomer shape that consistency factor, which can be referred to, 0 to 1, and nail set 110 is screwed in bone cements；Bone is screwed in nail set 110
Bone cement is waited to solidify substantially after removing the most of bone cement for entering mesoporous after cement.It will be set in the close solidification of bone cement
Nail 120 is screwed in nail set 110 by the cooperation of external screw thread 121 and internal screw thread.120 one side of nail of setting into nail set 110 can general
Remaining bone cement is expressed in discharge groove 112, and the expansion certain distance that two bulges 131 on the other hand can be made opposite makes
Higher fixation between nail set 110 and bone cement.After setting nail 120 and screwing in bone cement, the realization of nail disk 122 and remaining can be passed through
The connection of intervention apparatus.
Referring to FIG. 2, the present embodiment is configured with the expanding lid 132 of hollow out in the lower part of nail set 110, expanding lid 132 is used for
Together by two limitations of bulge 131, it prevents that helical blade 111 is caused to squeeze since bone cement coagulation grade is higher, makes
Bulge 131 shifts.The lower part configuration tip of nail 120 is set, then point can be passed through after screwing in nail set 110 by setting nail 120
End opens downwards expanding lid 132, and opposite deviate can be occurred by making bulge 131 again.
Referring to FIG. 3, the nail disk 122 of the present embodiment can be realized fast by a straight line traction mechanism and Universal locator
Speed sets the operation such as positioning and screw-in of nail 120.
Universal positioning mechanism and straight line traction mechanism, universal positioning mechanism adjust straight line for fixing with operating bed
Traction mechanism is opposite wait follow closely the surgery location for setting position.On the one hand straight line traction mechanism is used to proofread the surgery location for setting nail 120,
On the other hand for that will set inside the screw-in nail set 110 that nail 120 does not deviate.
Universal positioning mechanism includes fixture, and fixture includes upper clamp plate 200 and lower clamp plate 300, upper clamp plate 200 and lower clamp plate
Close up or separate by screw rod control between 300.Upper clamp plate 200 is fixed with the first universal shaft 410, the connection of the first universal shaft 410
There is the second universal shaft 420, the second universal shaft 420 connects straight line traction mechanism.
So through the above scheme, the universal positioning mechanism of the present embodiment can adjust the operation position of straight line traction mechanism
It sets, the precision of 120 operations of nail is set in the raising of mechanization.
Straight line traction mechanism includes the fixed plate 510 being bolted with the second universal shaft 420, and fixed plate 510 has two
It is a interval and the block 520 that is relatively fixed, the opposite side of two fixed blocks 520 offer sliding slot 521, fixed block at middle part
520 offer on top and lower part and run through and by 521 fixing groove 522 of sliding slot.
Straight line traction mechanism further comprises sliding block, and the both ends of sliding block are respectively erected on two sliding slots 521 and can
It is slid in sliding slot 521.
The present embodiment can be bolted sliding block after the top of block 520 and the fixing groove 522 of lower part and sliding slot 521
Relatively fixed block 520 is fixed.So the present embodiment is after sliding sliding block reaches preset surgery location, by bolt by fixed block
520 and sliding block be fixed.
Further, it is fixed with the mounting portion that there is mounting groove at a middle part in the middle part of sliding block, is equipped in mounting groove straight
Wire spring.Bull stick 530 is arranged in the linear springs of the present embodiment, one end of bull stick 530 has rotation to hold, for making medical care people
Member can hold and exert a force, and the other end has the link block 531 of rectangle, slotting for there is the link slot 532 on nail 122 top of disk to carry out
It connects.
The above is only preferred implementations of the invention, are not intended to restrict the invention, for those skilled in the art
For, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification, etc.
With replacement, improvement etc., should all be included in the protection scope of the present invention.
