Abstract
The utility model discloses the double pointed head Kirschner wires for being equipped with antiskid thread, it is made of needle body and the tip that needle body both ends are arranged in, inserting needle scale and antiskid thread section are provided on needle body, inserting needle marked level is arranged on the lateral surface of needle body, it is three centimetres that length, which is arranged, in antiskid thread section, and is separately positioned on two ends of needle body, and the screw thread of antiskid thread section and central cylindrical portion gradually finishes up and transition connects, the screw pitch of antiskid thread section is 0.1-0.6mm, and the depth of screw thread is 0.1-0.6mm.The utility model can effectively prevent the movement of bone, avoid the occurrence of the sliding of Kirschner wire, loosening, abjection, reduce pin track infection, accelerating bone healing.
Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to the double pointed head Kirschner wire equipped with antiskid thread.
Background technique
Kirschner wire is a kind of important internal fixation method, especially bone in children and articular trauma and bone in bone surgery treatment
Very widely used in the orthomorphia of joint, advantage is that expense is low, easy to operate, small to tissue damage.Existing Kirschner wire
Structure is one end point, and the other end is blunt, and does not have scale on needle, the disadvantage is that: (1) doctor cannot accurately control in the course of surgery
Depth of needle；(2) for needing the case of bidirectional operation, coarse oblique acute angle can only be temporarily cut out in blunt end, in this way
It will affect inserting needle speed and increase the destruction of bone and cartilage；(3) existing Kirschner wire is to be made of stainless steel, stainless steel
The biocompatibility of material is lower, and there are cell reactions in human body, improper to be retained in inside of human body for a long time.In addition, using
It will appear the complication such as Kirschner wire loosening, abjection, pin track infection, or even fixed failure in journey, sometimes have to removal and fix, weight
Newly fixed using other way.People also devise a variety of different Kirschner wires, but mostly because of strength reduction or attachment device excessively
Complexity can not be applied to clinic very well.
Utility model content
The purpose of the utility model is to provide one kind can effectively prevent Kirschner wire sliding, loosens, abjection, reduction screw way sense
Dye, the double pointed head Kirschner wire equipped with antiskid thread of accelerating bone healing.
The utility model is realized in this way the double pointed head Kirschner wire equipped with antiskid thread, by needle body and is arranged in needle
The tip at body both ends forms, and inserting needle scale and antiskid thread section are provided on the needle body, and the inserting needle marked level setting exists
On the lateral surface of needle body；The antiskid thread section setting length is three centimetres, and is separately positioned on two ends of needle body.
Further, the screw thread of the antiskid thread section and central cylindrical portion gradually finishes up and transition connects.
Further, the screw pitch of the antiskid thread section is 0.1-0.6mm, and the depth of screw thread is 0.1-0.6 mm.
Further, the scale division value that the inserting needle scale is one millimeter, and the tip respectively from two ends is every to needle body center
The number of corresponding needling length value is indicated every one centimetre, the needle body central point is marked equipped with zero graduation.
Further, the inserting needle scale is successively to be carved with number every one centimetre from the tip at two ends to needle body center respectively
Word 1,2,3,4,5,6,7,8,9,10,11,12,13.
Further, the tip is in trigone tip.
Further, the needle body and tip are whole made of titanium alloy material.
The beneficial effects of the utility model are:
1. the movement of bone can be effectively prevent, avoids the occurrence of the sliding of Kirschner wire, loosening, abjection, reduces pin track infection, add
Fast union.
2. doctor can accurately control depth of needle in the course of surgery, the accuracy and efficiency of surgical procedure can be improved；
3. double pointed head can improve surgical procedure without the oblique tip that Temporary shear is coarse for the case of bidirectional operation
Efficiency；And it can be reduced the destruction to bone and cartilage；Especially reducing can be to avoid the growth of bone to the damage of children's epiphyseal plate
Development；
4. the biocompatibility of titanium alloy material is higher than the biocompatibility of stainless steel material, it is more suitable for being retained in people for a long time
Internal portion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In attached drawing: 1, needle body, 11, inserting needle scale, 12, antiskid thread section, 2, tip.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below with reference to embodiment:
It is whole to be made of titanium alloy material as shown in Figure 1, be equipped with the double pointed head Kirschner wire of antiskid thread, by needle body 1 and
2 two parts of tip composition at 1 both ends of needle body is set, is provided with inserting needle scale 11 and antiskid thread section 12 on needle body 1, inserting needle is carved
Degree 11 is horizontally set on the lateral surface of needle body 1.It is three centimetres that length, which is arranged, in antiskid thread section 12, and is separately positioned on needle body 1
The screw thread of two ends, antiskid thread section and central cylindrical portion gradually finishes up and transition connects；The screw pitch of antiskid thread section 12
For 0.1mm, the depth of screw thread is 0.1mm.The scale division value that inserting needle scale 11 is one millimeter, and respectively from the tip 2 at two ends to needle
1 center of body indicates the number of corresponding needling length value every one centimetre, and 1 central point of needle body is marked equipped with zero graduation.Inserting needle scale
11 for be successively carved with from the tip 2 at two ends to 1 center of needle body every one centimetre respectively number 1,2,3,4,5,6,7,8,9,10,
11,12,13.Tip 2 is in trigone tip.
The above is only the preferred embodiment of the utility model, it is noted that for the ordinary skill people of this field
Member for, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these improve and
Retouching, which should also be as being considered as, to be within the protection scope of the utility model.
