Description
Technical Field
The utility model relates to a sewing needle, concretely relates to two lead wire loop sewing needles.
Background
With the development of sports medical technology, tendon reconstruction surgery is more and more widely applied, and the flow of tendon reconstruction surgery is as follows: extracted from tendon extractum → woven tendon → tunnel of tendon preparation → fixed tendon. After the self-extracting tendon is extracted, a tendon finishing platform, a suture needle and a suture are used for weaving the prepared tendon, the treated tendon is introduced into a tunnel, and then the operations such as tightening, fixing and the like are carried out by matching with a screw or a titanium plate, so that the purpose of reconstruction and repair operations is achieved.
Since the conventional suture needle is provided with a needle hole in the needle body itself, the threading is very inconvenient. In addition, the traditional tendon weaving mode is that double suture needles are used for left-right crossing and sequential operation, the operation is complicated, double needle hole wounds can be generated, great trauma is caused to the tendon, a clinical surgeon can only rely on experience and own operation technology, the injury to the tendon is reduced as much as possible, the uncertainty of the operation is increased, and therefore the risk of the operation is increased; and results in a relatively long procedure time.
Disclosure of Invention
The utility model discloses be exactly to prior art not enough, provide a two lead wire loop suture needle, shortened the operation time that the operation was woven to the tendon, improved work efficiency, the lead wire is more convenient, reduce and alleviateed the wound.
The technical scheme of the utility model is that:
a double-lead-ring suture needle is provided with a suture needle body, the front end of the suture needle body is provided with a needle point, one end of the suture needle body, which is far away from the needle point, is provided with a wire ring fixing hole, the double-lead-ring suture needle is also provided with two lead rings, and the two lead rings are jointly fixed in the wire ring fixing hole.
Preferably, one of the wire loops is a short wire loop and the other wire loop is a long wire loop.
Preferably, the short lead ring and the long lead ring are both made of high-strength elastic materials.
Preferably, the high-strength elastic material is a NiTi memory alloy.
The utility model has the advantages that:
1) the utility model is provided with double lead rings, and the operation time of tendon knitting operation is greatly shortened and the work efficiency of doctors is improved through the mode of 'one needle double thread'; and compared with the needle body provided with a pinhole, the wire loop is more convenient to lead.
2) The utility model discloses long lead ring and short lead ring collocation can realize the effect that the both ends of suture passed from a pinhole when weaving the tendon, have solved and have produced double pinhole wound to the big technical problem of tendon damage when using two suture needles to weave the tendon, and have guaranteed the intensity of weaving the back tendon.
3) The utility model discloses long lead ring and short lead ring collocation and two unanimous two lead rings of size are compared, have reduced two sews when weaving the tendon and have overlapped the technical problem that the fifty percent discount passed the wound that the tendon caused simultaneously and strengthened.
4) The lead ring is made of NiTi memory alloy, has the characteristics of high specific strength, wear resistance, corrosion resistance, no magnetism and good biocompatibility, and also has shape memory performance and super-elasticity performance.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the suture needle body of the present invention;
fig. 3 is a reference diagram of the application state of the present invention.
The symbols in the drawings illustrate that:
1. suturing the needle body; 1-1, wire loop fixing holes; 1-2. needle tip; 2. a short wire loop; 3. a long wire loop; 4. a suture; 5. a tendon; 6. tendon arrangement platform.
Detailed Description
The following describes in detail embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the utility model is provided with a suture needle body 1 and two lead rings, wherein the two lead rings are respectively a short lead ring 2 and a long lead ring 3, and the short lead ring 2 and the long lead ring 3 are made of NiTi memory alloy. The front end of the suture needle body 1 is provided with a needle point 1-2, one end far away from the needle point 1-2 is provided with a thread ring fixing hole 1-1, and the short thread ring 2 and the long thread ring 3 are jointly fixed in the thread ring fixing hole 1-1.
As shown in fig. 3, the utility model discloses a use method:
1) tensioning the tendon 5 to be woven, and fixing two ends of the tendon 5 on a tendon finishing platform 6 respectively;
2) fixing the middle part of the suture 4 at the bottom of the tendon 5 near one end;
3) the two ends of the suture line 4 are respectively encircled above the tendon 5 from the two sides of the tendon 5;
4) one end of the suture 4 is penetrated into the short lead ring 2, the other end is penetrated into the long lead ring 3, the utility model which is penetrated with the suture 4 is inserted from the top down with the distance set by the previous pinhole interval, the utility model is separated from the suture 4 after the two ends of the suture 4 and the utility model are both penetrated through the tendon 5, and the suture 4 is tensioned downwards;
repeating the steps 3) and 4), so that the present invention weaves the tendon 5 according to the cross-weaving method shown in fig. 3 until the suture 4 is knotted near the tendon 5 after the other end of the tendon 5, and the tail thread is cut off.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
However, the above description is only an embodiment of the present invention, and the scope of the present invention should not be limited thereto, so that the replacement of the equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should be covered by the claims of the present invention.
