A repair factor-loaded suture production device

Abstract

The invention discloses a repair factor-carrying suture production device, which comprises a bottom plate, a spinning device is fixed on the top of the bottom plate, a discharge port is provided on the front side of the spinning device, two intake ports are provided on the right side, and a built-in 5kV power supply is provided. , the two feeding ports of the spinning device are respectively connected with the output ends of the spinning solution injector and the repair factor injector, the solution inside the repair factor injector contains repair factor or nanoparticles, and the bottoms of both the spinning solution injector and the repair factor injector are connected to the bottom plate Top fixing, the present invention relates to the technical field of suture production. The repair factor-loaded suture production device achieves the continuous input of the spinning solution and the intermittent input of the repair factor, so that the surface shell of the suture spun by the spinning device is in an intermittent state, which can increase the shell layer on the suture. Part of the contact area with body tissue, thereby increasing the release rate of repair factors or nanoparticles.

Description

technical field [0001] The invention relates to the technical field of suture thread production, in particular to a repair factor-loaded suture thread production device. Background technique [0002] Sutures are widely used in clinical operations and play an important role in suturing wounds and connecting damaged tissues. With the development of technology, the materials used for sutures are also constantly improving and their functions are further enhanced. Generally speaking, the effective concentration of the drug must be maintained for a long time in the lesion site of the patient in order to exert a good effect. At present, some clinical drugs need to be injected in large doses intravenously to play their role, which not only has the disadvantage of excessive drug intake and strong side effects, but also reaches the lesions relatively slowly through blood circulation, resulting in poor therapeutic effect. Topical administration is an effective method to enhance drug ...

Problems solved by technology

At present, some clinical drugs need to be injected into large doses to play a role, which not only has the risk of excessive drug intake and the disadvantages of strong side effects, but also reaches the lesion through blood circulation relatively slowly, resulting in poor therapeutic effect. Topical administration is an effective way to enhance drug action and therapeutic efficacy

[0003] The existing sutures are usually loaded with repair factors or nanoparticles directly through the hydrolyzable sutures to improve the speed and effect of wound healing. However, after the production of the existing sutures, the surface of some sutures is relatively rough, which leads to sutures. During the suturing process, the suture produces secondary damage to the skin tissue at the suture, and the release rate of repair factors or nanoparticles on the existing suture is also slow, and the wound healing effect and speed are often poor
