Repair factor-loaded suture line production device

Abstract

The invention discloses a repair factor-loaded suture line production device. The repair factor-loaded suture line production device comprises a bottom plate, wherein a spinning device is fixed to the top of the bottom plate; a discharging port is formed in the front side of the spinning device; two feeding ports are formed in the right side of the spinning device; a 5kV power source is arranged in the spinning device; the two feeding ports of the spinning device are connected with the discharging end of a spinning solution injector and the discharging end of a repair factor injector respectively; a solution in the repair factor injector contains repair factors or nano particles; and the bottom of the spinning solution injector and the bottom of the repair factor injector are both fixed to the top of the bottom plate. The repair factor-loaded suture line production device provided by the invention relates to the technical field of suture line production. According to the repair factor-loaded suture line production device, continuous input of a spinning solution and intermittent input of repair factors are achieved, so that a surface shell layer of a suture line spun by a spinning device is in an intermittent state, the contact area between an upper shell layer part of the suture line and body tissues can be increased, and then the release speed of the repair factors or the nano particles is improved.

Description

technical field [0001] The invention relates to the technical field of suture production, in particular to a suture production device carrying a repair factor. 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 have also been continuously improved, and their functions have been further enhanced. Generally speaking, drugs must maintain an effective concentration for a long time at the lesion site in the patient's body to exert a good effect. 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 therap...

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
