Abstract

The utility model relates to a hollow nail guider for collum femoris, comprising a guide cylinder (1). The hollow nail guider is characterized in that a vertical handle (3) which is vertically and fixedly connected with the guide cylinder is arranged on the guide cylinder (1); and the vertical handle (3) is movably connected with an indicationrod (2). The utility model can realize simultaneous guide on two mutually vertical perspective planes without repeated adjustment on different planes so as to simplify the operation. After the guider is used, the embedding precision and success ratio of the hollow nail is improved, the exposure of X-ray is reduced, and the infection opportunity of the affected part of a patient is reduced simultaneously.

Description

Neck of femur hollow nail guider

Technical field

This utility model relates to a kind of medical bone neck hollow nail guider, is a kind of neck of femur hollow nail guider that can realize simultaneously guiding on mutually perpendicular two perspective planes specifically.

Background technology

At present, orthopaedics is clinical to carry out fracture of femoral neck when resetting drift bolt, most free-hand operation or adopt easy locating piece to operate, or adopt hollow nail guider commonly used as " product " the font guider that is used for neck of femur hollow nail internal fixation and the guider of sleeve sample, it advances the angle of nail, deflection error is bigger, be difficult to accurate assurance, and need be just, side position perspective downward modulation perfect square to, owing to once can only have an X-rayed a plane, so need under different perspective planes, adjust repeatedly, insert degree of accuracy thereby influence hollow nail, patient and medical worker's X ray expose many, operating time is long, and repeatedly adjusting perspective plane increases infection chance easily.

Someone has made some improvement at this deficiency, for example the disclosed name of Chinese patent (CN 2675069) is called the fracture of femoral neck into nail guider that resets, it has solved to a certain extent advances to follow closely angle, problem that deflection error is bigger, but still exist need just, side position perspective downward modulation perfect square to, owing to once can only have an X-rayed a plane, so need under different perspective planes, adjust repeatedly, thereby influence hollow nail and insert degree of accuracy, patient and medical worker's X ray expose many, operating time is long, and repeatedly adjusting perspective plane increases infection chance easily.

Also the someone has made such improvement, and for example the disclosed name of Chinese patent (CN 1657014) is called location-guiding apparatus for arranging internal guide meedle in femur neck, and its location is relatively accurate, but the structure more complicated, and program is more loaded down with trivial details.

Summary of the invention

This utility model has solved the problem that hollow nail that prior art exists is inserted degree of accuracy, and what a kind of hollow nail was provided inserts degree of accuracy and the high neck of femur hollow nail guider of success rate.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of neck of femur hollow nail guider, comprise guide cylinder, it is characterized in that perpendicular fixedly connected perpendicular handle is arranged on the described guide cylinder, flexibly connect indicating arm on this perpendicular handle.Described indicating arm is connected on the perpendicular handle by slide block, and described indicating arm is parallel with guide cylinder in sliding process.By this slide block, can be so that indicating arm slides on perpendicular handle under the prerequisite parallel with guide cylinder keeping, make between indicating arm and the guide cylinder apart from scalable.

As preferably, described guide cylinder tube end is provided with tooth angle.This tooth angle is in order to allow guide cylinder can better block skeleton, and stable when guaranteeing the guide pin inserting needle makes the location accurately.

As preferably, on the described guide cylinder centre bore is arranged.This centre bore is used for inserting guide pin.

This utility model is skillfully constructed, and indicating arm connects perpendicular handle by slide block, makes it have following beneficial effect compared with the prior art:

1, can on mutually perpendicular two perspective planes, realize guiding simultaneously, simplify operation;

2, use this guider after, that has improved hollow nail inserts degree of accuracy and success rate;

3, reduce the exposure of X ray, reduced the infection chance in patient affected part.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model:

Fig. 2 is the bonded perspective structure sketch map of guider and skeleton.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.

Embodiment 1.See Fig. 1 and Fig. 2, this routine a kind of neck of femur hollow nail guider, comprise guide cylinder 1, perpendicular fixedly connected perpendicular handle 3 is arranged on the described guide cylinder 1, this perpendicular handle 3 flexibly connects indicating arm 2 by slide block 4, and described indicating arm 2 is parallel with guide cylinder 1 in sliding process, and guide cylinder 1 is provided with the centre bore 6 of inserting guide pin, be provided with tooth angle 5 on the tube end of this guide cylinder 1, this tooth angle 5 is used for better locating when fixation hollow nail.

As shown in Figure 2, in the operation process, at first on the normotopia perspective plane, orient this inserting needle path, plane with Kirschner wire, and the markings in this path that on skin, draw, in operation, only need then the indicating arm on the guider is overlapped with the skin mark line, so just having guaranteed the collodiaphyseal angle guiding accurately, can be accurately to squeeze into the hollow nail guide pin on the side position at another perspective plane also, and typical case's operation is as neck of femur hollow nail internal fixation, dynamic hip screw internal fixation etc.It can realize guiding simultaneously on mutually perpendicular two perspective planes, not be used under the Different Plane and adjust repeatedly, simplified operation, therefore after using this guider, that has improved hollow nail inserts degree of accuracy and success rate, reduce the exposure of X ray simultaneously, reduced the infection chance in patient affected part.

It is apparent to one skilled in the art that this utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
