A kind of self-control steel wire inducting deviceTechnical field
The invention belongs to field of medical auxiliary equipment more particularly to a kind of self-control steel wire inducting devices.
Background technology
Currently, the prior art commonly used in the trade is such：
In bone surgery, it is sometimes desirable to bone be fixed with steel wire, but traditional steel wire imports armament-related work halfDiameter is insufficient, cannot flexibly be used when working range is larger, and it is relatively low that steel wire imports success rate；And detachably combine steel wire importingDevice utilizes external and internal compositions, can be relatively easy to import organization internal by steel wire, has obtained relatively broad application, but is detachableIt is larger to combine inducting device damage, being combined often has soft tissue insertion bayonet, causes combination to fail, steel wire is caused to can not be successfullyIt imports.
In conclusion problem of the existing technology is：
Traditional steel wire inducting device working range is smaller, cannot flexibly be used when working range is larger；Detachable groupIt is larger to close inducting device damage, is easy combination failure, success rate is low.
Invention content
In view of the problems of the existing technology, the present invention provides a kind of self-control steel wire inducting devices.
The invention is realized in this way a kind of self-control steel wire inducting device is made of outer sleeve and inner sleeve；
The outer sleeve and inner sleeve are semicircle, and outer sleeve is socketed in the outside of inner sleeve；
Inner sleeve tail end is welded with handle, is used for hand-held；
It is welded with connector on the downside of outer sleeve tail end, connector is connected with outer sleeve pitman by shaft, for operatingOuter sleeve is moved relative to inner sleeve.
Further, outer sleeve is tapered with inner sleeve from handle one end to tip, conveniently penetrates organization internal.
Further, sliding slot is offered on the inside of outer sleeve, and the sliding slot fixed point being mutually clamped with sliding slot is welded on the outside of inner sleeve,For limiting sliding position of the outer sleeve on the outside of inner sleeve.
Further, handle offers fluting, and outer sleeve pitman is connected to fluting inside.
Advantages of the present invention and good effect are：
In conclusion advantages of the present invention and good effect are：
The present invention is slided by outer sleeve on the outside of inner sleeve, and length is scalable, and inner sleeve handle and sleeve are at 45 °,The design can increase inducting device working range.Inside and outside sleeve is gradually reduced from one end to the other side, and one end is tip, this is facilitated to leadEnter device and carries out soft tissue opening.Outer sleeve is socketed with inner sleeve, is easily introduced into and is exited, and small notch can be operated, and damage is smaller,And steel wire imports success rate height.

Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present inventionIt is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used toLimit the present invention.
As shown in Figure 1, self-control steel wire inducting device provided in an embodiment of the present invention includes：Outer sleeve 1, inner sleeve 2, sliding slot3, sliding slot fixed point 4, connector 5, outer sleeve pitman 6, handle 7, fluting 8, steel wire 9.
Outer sleeve 1 and inner sleeve 2 are semicircle, and outer sleeve 1 is socketed in the outside of inner sleeve 2；2 tail end of inner sleeve weldsThere is handle 7, is welded with connector 5 on the downside of 1 tail end of outer sleeve, connector 5 is connected with outer sleeve pitman 6, housing by shaftCylinder 1 is tapered with inner sleeve 2 from 7 one end of handle to tip, and 1 inside of outer sleeve offers sliding slot 3,2 outside welding of inner sleeveThere is the sliding slot fixed point 4 being clamped with 3 phase of sliding slot.
Handle 7 offers fluting 8, and outer sleeve pitman 6 is connected to 8 inside of fluting.
The present invention, can will be outer by outer sleeve pitman 6 by stretching into outer sleeve 1 in the tissue of steel wire 10 to be importedSleeve 1 pushes forward, extends the importing distance of steel wire 10, and sliding slot fixed point 4 is clamped with 3 phase of sliding slot, exists for limiting outer sleeve 1The sliding position in the outside of inner sleeve 2, prevents outer sleeve 1 from slipping, penetrates into after suitable position, by steel wire 10 from inner sleeve 2Tail end penetrates so that steel wire 10 is pierced by from 1 tip of outer sleeve, finally entirely extracts inducting device from steel wire 10 out, you can completesImporting to steel wire 10.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present inventionAll any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
