Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically a kind of device for taking out broken nail and broken nail withdrawing device.
Background technology
Clinically, after spinal column, extremity internal fixation operation, because the pot life causes metal fatigue, often there will be broken nail phenomenon.
At present, the device for taking out broken nail that doctor uses, after usually needing the sclerotin around by broken nail all to reject, could take out broken nail, when this mode takes out broken nail, consuming time longer, larger to sclerotin injury.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of device for taking out broken nail and broken nail withdrawing device, less to osseous tissue damage; The broken nail of different-diameter size can be taken out.
For reaching above object, the technical scheme that this utility model is taked is: a kind of device for taking out broken nail, comprises sleeve pipe, the top of this sleeve pipe is set with a rotary handle, the bottom of sleeve pipe has female thread, and described rotary handle is in the form of annular discs, and the center of rotary handle offers installing hole; The top of sleeve pipe is fixedly plugged in the installing hole of rotary handle, and the opening of cannula tip and ft connection.
Further improvement is: described casing length is 50mm ~ 100mm, and sleeve pipe caliber is 3mm ~ 10mm.
Further improvement is: described sleeve pipe is stainless steel.
Further improvement is: the length of described casing shoe female thread is 30mm.
The invention also discloses a kind of broken nail withdrawing device based on above-mentioned device for taking out broken nail, comprise two device for taking out broken nail, and the sleeve pipe caliber of two device for taking out broken nail is different, wherein, the device for taking out broken nail that sleeve pipe caliber is less is top-down is inserted in the larger device for taking out broken nail of sleeve pipe caliber.
Further improvement is: the device for taking out broken nail length that sleeve pipe caliber is less is not less than the larger device for taking out broken nail length of sleeve pipe caliber.
The beneficial effects of the utility model are:
1, not needing when taking out broken nail all to reject the sclerotin surrounding broken nail, only need reject the sclerotin of broken nail afterbody, as long as sleeve pipe can block broken nail tailing screw flight just progressively can take out broken nail, simple and fast by the rotation of both forward and reverse directions, and less to osseous tissue damage.
2, in this utility model, broken nail withdrawing device comprises the sleeve pipe of two different tube diameters, can take out the broken nail of different-diameter size.
Accompanying drawing explanation
Fig. 1 is the structural representation of device for taking out broken nail in this utility model embodiment.
Fig. 2 is device for taking out broken nail using state figure in this utility model embodiment.
Fig. 3 is the using state figure of broken nail withdrawing device in this utility model embodiment.
Reference numeral:
1--sleeve pipe, 2--rotary handle, 3--female thread, 4--installing hole, 5--broken nail.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, this utility model provides a kind of device for taking out broken nail, comprises sleeve pipe 1, concrete, and sleeve pipe 1 is stainless steel, and sleeve pipe 1 length is for being 50mm ~ 100mm, and sleeve pipe 1 caliber is 3mm ~ 10mm.The top of this sleeve pipe 1 is set with a rotary handle 2, and the bottom of sleeve pipe 1 has female thread 3, concrete, and the length of sleeve pipe 1 bottom female thread 3 is 30mm.Described rotary handle 2 is in the form of annular discs, and the center of rotary handle 2 offers installing hole 4; The top of sleeve pipe 1 is fixedly plugged in the installing hole 4 of rotary handle 2, and the opening on sleeve pipe 1 top and ft connection.
Shown in Figure 3, this utility model also provides a kind of broken nail withdrawing device based on above-mentioned device for taking out broken nail, comprise the device for taking out broken nail of two or more model, and sleeve pipe 1 caliber of the device for taking out broken nail of every two models is different, wherein, the device for taking out broken nail that sleeve pipe 1 caliber is less is top-down to be inserted in the larger device for taking out broken nail of sleeve pipe 1 caliber.Therefore, when the caliber of sleeve pipe 1 is greater than the diameter of broken nail 5, by the sleeve pipe 1 that plug-in mounting caliber in the larger sleeve pipe of caliber 1 is less, and caliber equals the diameter of broken nail 5 compared with the caliber of small casing 1, and broken nail 5 screws out by the sleeve pipe 1 making caliber less from sclerotin.The device for taking out broken nail length that sleeve pipe caliber is less is not less than the larger device for taking out broken nail length of sleeve pipe caliber, facilitates caliber compared with the external screw thread of the female thread 3 precession broken nail 5 of small casing 1 bottom.
As shown in Figure 2, the use principle of device for taking out broken nail is:
A sleeve pipe 1 is entangled broken nail 5, the rotary handle 2 on operator's revoling tube 1 top, the external screw thread of the female thread 3 making sleeve pipe 1 bottom progressively precession broken nail, and then broken nail is screwed out from sclerotin.
As shown in Figure 3, the use principle of broken nail withdrawing device is:
First a sleeve pipe 1 is entangled broken nail 5, if the caliber of this sleeve pipe 1 equals the diameter of broken nail 5, then the rotary handle 2 on operator's revoling tube 1 top, the external screw thread of the female thread 3 making sleeve pipe 1 bottom progressively precession broken nail, and then broken nail is screwed out from sclerotin.
If the caliber of sleeve pipe 1 is greater than the diameter of broken nail, when then using, this sleeve pipe 1 cannot block broken nail, now, can in the sleeve pipe 1 that caliber is larger the sleeve pipe 1 of plug-in mounting caliber less (caliber equals the diameter of broken nail 5), then operator rotate and are positioned at the rotary handle 2 of caliber compared with small casing 1 top, make caliber compared with the external screw thread of the female thread 3 progressively precession broken nail of small casing 1 bottom, and then are screwed out from sclerotin by broken nail.
This utility model is not only confined to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with this utility model or akin technical scheme, all within its protection domain.
