Abstract

The utility model relates to a medical device, especially, relate to a reduction of the fracture gram formula needle director. A reduction of the fracture gram formula needle director, including circular director body and handle, the director body is cheng integrative with handle interconnect that is used for the shallow table position of four limbs. this internal guide way that is equipped with of director, gram formula needle director are gone up on original basis and are changed the front end into the inclined plane design that inclines, increase the direction tooth simultaneously, through distributing evenly and having the direction tooth of slope, form stronger grasp, after the direction, improved the accuracy of threading a needle, prevent to thread a needle many times and stay the hypodermic needle eye at four limbs shallow table positions, result in aesthetic problems, reducing threads a needle many times also can accelerate the union.

Description

Reduction of the fracture Kirschner wire guider for extremity superficial place

Technical field

This utility model is related to a kind of armarium, more particularly, to a kind of reduction of the fracture K-wire guider.

Background technology

The reduction of the fracture of extremity superficial place needs to be fixed with Kirschner wire, hollow screw, before to the angle direction threaded a needle Be all by doctor experimental technology operation complete, so often cannot be accurately positioned, need repeated localised puncture, union of fracture is had Harmful effect, is also easy to cause epidermis multiple eyelets, all can affect epidermis attractive in appearance after healing；Existing a lot of guider passes through It has been measured the calculating of the angle direction threaded a needle, but extremity superficial place is outer due to position, fixing difficult, be not suitable for using More complicated fracture setting device.

Content of the invention

The purpose of this utility model is：In view of the shortcomings of the prior art, provide a kind of structure simple, guide effect is good The reduction of the fracture Kirschner wire guider for extremity superficial place.

For realizing the purpose of this utility model, employ the following technical solutions and be achieved：

For the reduction of the fracture K-wire guider of extremity superficial place, including circular guider body and handle, guiding Device body and handle are connected with each other integral, are provided with gathering sill, the end of guider body is inclined in described guider body Shape；Connecting rod and the handlebar being connected by side plate bending is included on described handle, handlebar tilts laterally.

Preferably, described skewed surface is provided with downward-sloping guiding tooth, and guiding tooth is uniformly distributed in On the described guider body end face of described gathering sill both sides, symmetrically there is guiding tooth both sides respectively, are to prevent to not guiding tooth Break away.

Preferably, the downward-sloping angle [alpha] of tooth surface of described guiding tooth is 45-60 °, downward-sloping be in order to Preferably firmly grasp percutaneous, prevent its skidding.

Compared with prior art, the beneficial effects of the utility model are：K-wire guider handle on the basis of original Front end is changed to inclined plane design, increases guiding tooth simultaneously, by being evenly distributed and carrying the guiding tooth of inclination, is formed stronger Grasp；After guiding, improve the accuracy threaded a needle, preventing from repeatedly threading a needle leaves pinprick in extremity superficial place, and impact is beautiful See；Minimizing is repeatedly threaded a needle also can accelerating union of bone fracture.

Brief description

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation that this utility model guides tooth 6 distribution；

Fig. 3 is the A side enlarged drawing of Fig. 1.

Specific embodiment

Below according to accompanying drawing 1-3, specific embodiment of the present utility model is made a detailed explanation.

Embodiment

For the reduction of the fracture K-wire guider of extremity superficial place, including circular guider body 1 and handle 2, lead It is connected with each other to device body 1 and handle 2 integral, in described guider body 1, be provided with gathering sill 3, the end of guider body 1 Obliquely；Connecting rod 4 and the handlebar 5 being connected by side plate bending is included on described handle 2, handlebar 5 tilts laterally, institute State skewed surface and be provided with downward-sloping guiding tooth 6, guiding tooth 6 is uniformly distributed in the guider of gathering sill 3 both sides originally On body 1 end face, the angle [alpha] that the tooth surface of described guiding tooth 5 is downward-sloping is 45-60 °.

When using, hold handle 2, K-wire is penetrated in guider body, the sharp end using inclined plane is easily inserted Enter skin superficial portion, press downwards after insertion, now the guiding tooth 5 in inclined plane inserts, can small range rotation at any time lead To device body 1, be not in the situation skidded or deviate from, change its angle after rotation, find most suitable entry point, start Inserting needle.

Claims

1. it is used for the reduction of the fracture K-wire guider of extremity superficial place, including circular guider body and handle, guider Body and handle are connected with each other integral it is characterised in that being provided with gathering sill, the end of guider body in described guider body Portion is oblique；Connecting rod and the handlebar being connected by side plate bending is included on described handle, handlebar tilts laterally.

2. the reduction of the fracture K-wire guider for extremity superficial place according to claim 1 is it is characterised in that institute State skewed surface and be provided with downward-sloping guiding tooth, guiding tooth is uniformly distributed in the described guiding of described gathering sill both sides On device body end face.

3. the reduction of the fracture K-wire guider for extremity superficial place according to claim 2 is it is characterised in that institute The downward-sloping angle [alpha] of tooth surface stating guiding tooth is 45-60 °.
