Abstract
The utility model relates to a medical binding suture, and particularly to a binding suture which is manufactured by titanium-nickel memory wire as the raw material. The binding suture comprises a linear memory alloy wire which has no shape memory recovery function characteristic under the human body temperature after heat treatment. The linear memory alloy wire depends on excellent biocompatibility of the memory alloy material and non-magnetic performance of the memory alloy. The material is denatured through a special treatment process for obtaining no shape memory recovery function characteristic and excellent plasticity and strength under the human body temperature. The material is softened for facilitating binding tightly in a medical operation process and obtaining an ideal medical operation effect.
Description
Technical field
This utility model relates to a kind of medical suture of tying up, be particularly related to a kind of with the suture of tying up of ti-ni shape memory alloy silk as the raw material making, rely on the nonmagnetic performance of memory alloy material excellent biological compatibility and memorial alloy, make the material degeneration by the special process processing, reach amorphism reminiscence function and good plasticity and intensity under human body temperature, make the material softness in operation process, be convenient to tie up tighten, reach the purpose that various operations are suitable for.
Background technology
At present, the medical metal that uses is clinically tied up suture stainless steel silk material.Owing to after using the stainless steel silk material, can leave pseudo-shadow, and the influence diagnosis causes mistaken diagnosis, brings many unnecessary troubles for diagnosis and operation at the nuclear magnetic resonance image lesions position.
Summary of the invention
In order to overcome current material many unfavorable factors clinically, the utility model proposes a kind of with the suture of tying up of ti-ni shape memory alloy silk as the raw material making.
Technical solution of the present utility model is:
A kind of ti-ni shape memory alloy of memoryless characteristic is tied up suture, and its special character is: it comprises linear memory alloy wire 1, and described memory alloy wire 1 is through being presented on the memory alloy wire of amorphism reminiscence functional characteristic under the human body temperature after the Overheating Treatment.
Also comprise the semicircle looper 2 that links to each other with memory alloy wire 1 one ends.
Also comprise the round staight needle 3 that is connected respectively with memory alloy wire 1 both ends.
The utility model has the advantages that:
This utility model utilizes the memorial alloy excellent biological compatibility, and is nonmagnetic, reaches amorphism reminiscence functional characteristic and good plasticity and intensity under human body temperature, makes the material softness.This utility model is simple in structure, is convenient to tie up in operation process tighten, and is easy to operate, reaches the purpose that various operations are suitable for.This utility model is nonmagnetic, pseudo-shadow can not occur on nuclear magnetic resonance image, helps diagnosis.This shows that the designed ti-ni shape memory alloy of this utility model is tied up suture can satisfy needs the clinical operation process on structure and operation principle.
Description of drawings
Fig. 1 is that this utility model is not with the structural representation of medical suture needle;
Fig. 2 is the structural representation of an end band semicircle looper of this utility model bounding wire;
Fig. 3 is the structural representation that the two ends of this utility model bounding wire have round staight needle;
The specific embodiment
This utility model ti-ni shape memory alloy Medical Cosmetic Collagen Injection stitching thread adopts the linear ti-ni shape memory alloy silk of different-diameter, different length to make, the material of this ti-ni shape memory alloy silk through after the Overheating Treatment under human body temperature amorphism reminiscence functional characteristic, but have plasticity, so has the function that to tie up, tighten.The one or both ends of this memorial alloy line can not connect sewing needle, also can be connected with medical suture needle.Medical suture needle can adopt semicircle looper or circle staight needle, also can adopt the rustless steel sewing needle.
This utility model principle: it mainly is the biocompatibility that has utilized memorial alloy, nonmagnetic, memoryless property, plasticity that ti-ni shape memory alloy is tied up suture.After Overheating Treatment, can change the performance of memory, have the function that to tie up, tighten.
