Nickel-titanium suture manufacturers believe that nickel-titanium alloy is a binary alloy composed of nickel and titanium. In addition to its unique shape memory function, it also has a series of excellent properties, making it a highly functional material for nickel-titanium sutures.
1. Shape memory characteristic. Nickel-titanium sutures can be deformed by external force at a certain temperature, and after the force is removed, they can maintain the deformed shape, but at a higher temperature, they can automatically return to their original shape.
2. Strong elasticity. Nickel-titanium suture manufacturers believe that the superelasticity of nickel-titanium alloy sutures varies with heat treatment conditions. When nickel-titanium alloy wire is heated to 400, the superelasticity begins to decrease.
3. Corrosion resistance. Nickel-titanium alloy sutures have excellent corrosion resistance compared to good medical stainless steel, making them widely used in the medical field.
4. Biocompatibility. Nickel-titanium suture manufacturers believe that although nickel is carcinogenic, the titanium dioxide on the surface of nickel-titanium acts as a barrier, inhibiting the release of nickel, giving nickel-titanium good biocompatibility.
5. Good shock absorption. The initial amplitude of superelastic nickel-titanium alloy sutures is only half that of stainless steel wire.
Nickel-titanium suture manufacturers believe that currently medical sutures are mainly divided into absorbable sutures and non-absorbable sutures. The difference between these two types of sutures can be clearly judged from their literal meanings. Absorbable sutures are absorbed by the human body after suturing and do not require removal, while non-absorbable sutures are not absorbed and need to be removed after a period of time. Surgical suturing has a long history in China. Early suture materials were mulberry bark thread, which is the inner bark fiber of the mulberry root. By processing the fiber into fine thread, this thread was used for suturing and was widely used due to its ease of production.
Nickel-titanium sutures belong to absorbable sutures and can be set with different phase transition temperatures according to clinical needs to adjust mechanical properties. They are very soft at room temperature but become elastic straight lines after entering the human body, capable of automatically closing the wound tissue.
Advantages of nickel-titanium sutures:
1. Relatively low incidence of adverse reactions;
2. Simple operation;
3. Easy removal;
4. Can effectively ensure skin suturing effect;
5. Can continuously apply pressure to the skin, resulting in good suturing effect.
Nickel-titanium sutures are a new type of medical suture, belonging to high-quality medical consumables, widely used in clinical surgical operations. Nickel-titanium sutures are mainly composed of nickel-titanium memory alloy wire (NiTi alloy) and medical suture needles, forming a functional special suture suitable for soft tissue suturing in the human body.
