AI Technical Summary

Technical Problem

Traditional suturing techniques can easily lead to the accumulation of blood and tissue fluid in the surgical area after surgery, increasing the risk of infection and prolonging recovery time, which is difficult to effectively solve with existing techniques.

Method used

The suture is designed with drainage function, and a drainage channel along the length of the suture is set to connect with the tissue needle channel to ensure that the exudate can be drained away quickly. At the same time, a guide groove is set on the suture needle to reduce the negative pressure restriction of the tissue on the needle body.

Benefits of technology

It effectively reduces the accumulation of blood and tissue fluid in the postoperative suture area, lowers the risk of infection and tissue swelling, promotes wound healing, provides personalized suturing solutions to meet different surgical needs, and reduces intraoperative bleeding and tissue trauma.

Abstract

A suture (1) having a drainage function, and a surgical suturing instrument using the suture (1). The suture (1) comprises a suture body; a drainage channel (10) passing through the suture body along the length direction thereof is provided in the middle or side portion of the suture body; the drainage channel (10) is communicated with a tissue needle tract, and is used for draining fluid from the tissue needle tract and a sutured region, so as to avoid exacerbated edema in a wound region, delayed healing, infection and the like caused by ineffective drainage of generated blood or tissue fluid; and in order to prevent the drainage channel (10) from being blocked, an anticoagulant coating is provided in the drainage channel (10), and a suture needle (3) provided with longitudinal groove bodies (30) and connected to the suture (1) is further provided.
