Description
Technical field
The utility model is related to medical instruments field, especially a kind of skid-off-proof type traction bow for treating fracture.
Background technology
Fixed thick steel needle traction bow is common a kind of medical instrument in operation, is drawn when performing the operation for Orthopedic correction
With.Current existing fixed thick steel needle traction bow is only screwed into sleeve with bolt, to withstand draw point, it is made to fix.But due to
Draw point surface is smooth, along with patient cannot keep stationary, is moved so the skidding for easily causing draw point is de-, but if
Anti-skid device is set at draw point, and is easy to impact affected part.
Utility model content
Shifting is taken off in order to overcome the shortcomings of that existing traction bow can not prevent draw point from skidding, the utility model provides a kind of anti-
Slippage type traction bow for treating fracture.
Technical solution adopted by the utility model to solve its technical problems is：A kind of skid-off-proof type fractures traction
Bow, including u-bracket, sleeve and fixing bolt, two ends of u-bracket, which are respectively welded, is connected with sleeve, the stack shell of sleeve
It is equipped with perforation, the inner wall of sleeve is equipped with screw thread, and fixing bolt passes through the perforation on sleeve, and is connect with bush whorl, U-shaped
It is connected respectively with there is l-shaped rod on two hack levers of holder, the bottom end of l-shaped rod is fixedly connected with positioning tube, positioning tube opening disposition
Opposite at sleeve openings is fixedly connected with suppressing device in positioning tube.
Another embodiment according to the present utility model, further comprises being welded and connected with spring body in the head of l-shaped rod
One, one upper end of spring body is welded and connected with briquetting, and briquetting is placed in outside l-shaped rod, and fixation is respectively equipped on two hack levers of u-bracket
Hole, the briquetting in l-shaped rod pass through mounting hole, and bottom end and the positioning tube of l-shaped rod are welded to connect.
Another embodiment according to the present utility model further comprises suppressing device by spring body two and rubber block group
At two one end of spring body is welded to connect in positioning tube, and the other end is buckled on rubber block.
The utility model has the beneficial effects that the utility model can effectively prevent the de- shifting of draw point, to reduce sufferer
The probability of secondary injury is caused in leg, ensure that therapeutic effect.

1.U types holder in figure, 2. sleeves, 3. fixing bolts, 4.L type bars, 5. positioning tubes, 6. spring bodies one, 7. briquettings, 8.
Mounting hole, 9. spring bodies two, 10. rubber blocks.
Specific implementation mode
If Fig. 1 is the structural schematic diagram of the utility model, Fig. 2 is state diagram when traction bow loads onto draw point, and Fig. 3 is L-type
The structural schematic diagram of bar, Fig. 4 are the state diagrams when briquetting in l-shaped rod is pressed in interior, and a kind of skid-off-proof type fractures are led
It draws a bow, including u-bracket 1, sleeve 2 and fixing bolt 3, two ends of u-bracket 1, which are respectively welded, is connected with sleeve 2, sleeve
2 stack shell is equipped with perforation, and the inner wall of sleeve 2 is equipped with screw thread, and fixing bolt 3 passes through the perforation on sleeve 2, and with sleeve 2
It is threadedly coupled, is connected respectively with there is l-shaped rod 4 on two hack levers of u-bracket 1, the bottom end of l-shaped rod 4 is fixedly connected with positioning tube
5,5 opening of positioning tube is placed in the opposite of 2 opening of sleeve, and suppressing device, the head of l-shaped rod 4 are fixedly connected in positioning tube 5
It is inside welded and connected with spring body 1, one 6 upper end of spring body is welded and connected with briquetting 7, and briquetting 7 is placed in outside l-shaped rod 4, u-bracket 1
Two hack levers on be respectively equipped with mounting hole 8, the briquetting 7 in l-shaped rod 4 passes through mounting hole 8, the bottom end of l-shaped rod 4 and positioning tube 5
It being welded to connect, suppressing device is made of spring body 29 and rubber block 10, and 29 one end of spring body is welded to connect in positioning tube 5,
The other end is buckled on rubber block 10.
In use, first draw point is passed through to the soft tissue being attached on bone to be corrected, u-bracket 1 is then held
Two bodies of rod, then break into two with one's hands outward with strength, and then the sleeve 2 of 1 two body of rod bottom ends of u-bracket is covered respectively again and is set to draw point
At needle point and backshank, fixing bolt 3 is tightened then through spiral, the top of such fixing bolt 3 is just withstood draw point and completed just
Step is fixed.
After draw point has tentatively fixed, the l-shaped rod 4 of two connection positioning tubes 5 is just inserted into u-bracket 1 respectively
In mounting hole 8 on shaft.The briquetting 7 in the head of l-shaped rod 4 is first pressed into interior (as shown in Fig. 4) before being inserted into, is being protected
It holds in the state that briquetting 7 do not expose head, passes through mounting hole 8, briquetting 7 can be in the effect of the recovery deformation of spring body 1 later
Test goes out head, to complete the limit of l-shaped rod 4 and u-bracket 1.
And while l-shaped rod is inserted into mounting hole 8, two positioning tubes 5 in left and right are also respectively the syringe needle of draw point and backshank set
It being set in positioning tube 5, during being arranged, syringe needle and backshank can withstand on rubber block 10 and squeeze spring body 29, to
Keep the positioning (as shown in Fig. 2) of draw point, such fixed form that can not have in draw point using the pressure of spring body 29
Upper setting anti-skid device avoids the slippage of draw point in the case where ensureing that puncture does not aggravate patient burden.The utility model can be with
It effectively prevent the de- shifting of draw point to ensure that therapeutic effect to reduce the probability that secondary injury is caused in sufferer leg.
