The utility model provides a pressurization spicule easily processes, is favorable to putting forward high pressure heater working medium volume, improves medical efficiency, reduces medical cost, but also can regard as the guide needle to use, and it is very convenient to use.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of pressurization spicule.
Background technology
In recent years, along with the development of communications, building industry etc., the Annual occurence rate of fracture is in rising trend, and
Being current topmost effective Therapeutic Method by surgical operation, the purpose of operation is again to recover fracture
Normal sequence and curvature, height and mobility, maintain original stability, and improve pressurized function of nervous system.
Along with all kinds of new operations are theoretical and the improvement of technique for fixing, clinical operation method is also continuously available improvement, uses
Spicule internal fixation treatment fracture is maximally effective Therapeutic Method.
Medical pressure spicule is generally used in orthopaedics internal fixation operation, by using pressurization principle, to fractured bones
Block is directly fixed, and engages the broken ends of fractured bone or the osteotomy end of fracture, and fixed effect is good, spicule conduct of pressurizeing
The existing over one hundred year history of internal fixation apparatus.
The screw thread of pitch gradual change is set on existing pressurization spicule outer surface, along with spicule enters sclerotin, due to
Pitch, the speed that each position of spicule enters sclerotin is different, the different pressure producing fracture face, right
Pressurize in fracture face.But existing spicule itself is relatively fine, gradual change screw thread is set in its surface, processing
Difficulty is relatively big, relatively costly, improves medical treatment cost to a certain extent.
Utility model content
The purpose of this utility model is to provide a kind of pressurization spicule, and processing is simple, low cost, solves existing
Have that spicule difficulty of processing is big, cost is high, improve the technical problem of medical treatment cost to a certain extent.
This utility model is achieved in that a kind of pressurization spicule, and described pressurization spicule includes the pin of cylinder
Body, the two ends of described needle body are equipped with point, and on described needle body, the part of the point of close one end is provided with
First constant worm pich, described needle body is provided with the second constant worm pich being connected with described first constant worm pich, institute
State the pitch pitch more than described second constant worm pich of the first constant worm pich.
Improving as one, the part that described needle body arranges the first constant worm pich and the second constant worm pich is cone
Platform, described first constant worm pich and the second constant worm pich taper into towards the orient diameter of point, described
The small end of frustum connects point, and the area of described frustum small end adapts with the area of described point.
As improving further, described point is that trihedral is most advanced and sophisticated.
Owing to using technique scheme, the beneficial effects of the utility model are:
Owing to pressurization spicule includes the needle body of cylinder, the two ends of needle body are equipped with point, close on needle body
The part of the point of one end is provided with the first constant worm pich and the second equidistant spiral shell being connected with the first constant worm pich
Stricture of vagina, and the pitch of the first constant worm pich is more than the pitch of the second constant worm pich so that and this utility model provides
Pressurization spicule compared with the existing spicule that gradual change screw thread is set, greatly reduce difficulty of processing, reduce and add
Work cost, and be conducive to improving crudy, improve medical effect, reduce medical treatment cost.
The two ends of the pressurization spicule that this this utility model provides can use, it is possible to use be threaded
End is cut off the other end and is purely by way of pressurization spicule use, it is also possible to cut off one end work that pressurization spicule is threaded
For guiding pin to use, very easy to use.
It is frustum owing to arranging the part of the first constant worm pich and the second constant worm pich on needle body, the first equidistant spiral shell
Stricture of vagina and the second constant worm pich taper into towards the orient diameter of point, and the small end of frustum connects point,
The area of frustum small end adapts with the area of point, and convenient pressurization spicule gos deep in sclerotin, non-during use
The most convenient.
Owing to point is that trihedral is most advanced and sophisticated, simple in construction, using effect is good, and is easy to processing.

Fig. 1 is the structural representation of this utility model embodiment one；
Fig. 2 is the structural representation of this utility model embodiment two；
Wherein, 1-needle body, 2-point, 3-the first constant worm pich, 4-the second constant worm pich.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
Embodiment one
As it is shown in figure 1, a kind of pressurization spicule, pressurization spicule includes the needle body 1 of cylinder, the two ends of needle body 1
Being equipped with point 2, on needle body 1, the part of the point 2 of close one end is provided with the first constant worm pich 3, pin
Body 1 is provided with the second constant worm pich 4 being connected with the first constant worm pich 3, and the pitch of the first constant worm pich 3 is big
Pitch in the second constant worm pich 4.
In the present embodiment, point 2 is that trihedral is most advanced and sophisticated.
In the present embodiment, pressurization spicule employing medical titanium alloy or medical stainless steel, this kind of strength of materials height,
Mechanical property, close to people's bone, also has the features such as endurance, corrosion-resistant and biocompatibility be excellent, extensively uses
In various artificial joint artificial bones, bone fixation means, artificial tooth, embedding, the fixed bridge of gear division etc..This material is tied
Close the pressurization spicule that the technical scheme of the present embodiment is made, there is the tensioning function that pressurizes well, it is possible to effectively
Ground promotes the growth of skeleton, shortens the convalescence of patient, alleviates the misery of patient.
Embodiment two
As in figure 2 it is shown, the present embodiment and embodiment one have essentially identical configuration, its difference is,
The part arranging the first constant worm pich 3 and the second constant worm pich 4 on needle body 1 is frustum, the first constant worm pich 3
