Description

Drainage device

technical field

The utility model relates to the field of anorectal treatment devices, in particular to a drainage device.

Background technique

According to the theory of anal gland infection, perianal abscess is an acute and chronic purulent disease caused by bacterial infection of anal crypts to form an inflammatory reaction and spread to the perianal tissue space through the anal gland duct. If not treated in time or improperly treated, anal fistula will form in the later stage, and secondary infection of anal fistula will lead to the formation of perianal abscess. Therefore, perianal abscess and anal fistula are not only different stages of development of a disease, but also affect each other. close. At present, surgery is a clinically effective treatment method. Surgical treatment of perianal abscess often adopts fractional surgery, that is, the pus is first incised and drained, and the pus is fully drained. The abscess cavity is narrowed and a straight or curved channel is formed. After the anal fistula is formed, the second-stage operation is performed. For the complex anal fistula, the tunnel-type dragging technique and catheter placement can minimize the damage to the tissues around the anus and are effective. It protects the integrity of the normal form and function of the anorectum, and minimizes the anal canal defect caused by scar tissue, but the operation process is cumbersome. Exploring the abscess cavity causes severe pain for the patient, and the rubber catheter is not easy to indwell for a long time, and the rubber becomes brittle, broken, and even falls into the deep wound surface for secondary infection. If the drag wire is left for a long time, problems such as deterioration and odor will occur, and it needs to be replaced regularly. For patients who need to indwell a drainage device for a long time, such as patients with Crohn's perianal disease, it is obviously more painful.
