A closed repair device for rectovaginal fistula

Abstract

An occlusion repair device for rectovaginal fistula comprises a first needle hole shell, a second needle hole shell, a first magnet and a second magnet. The body of the first needle hole shell is a first arc-shaped outer shell with a first groove formed in the end face in the arc length direction, and first connecting portions with connecting shafts are arranged at the two ends of the first outer shell. The body of the second needle hole shell is a second arc-shaped outer shell with a second groove formed in the end face in the arc length direction, second connecting portions with connecting holes are arranged at the two ends of the second outer shell, the connecting holes are used for being connected with the connecting shafts so as to connect the two end portions of the first needle hole shell and the two end portions of the second needle hole shell, and the second needle hole shell can rotate around the connecting shafts after the connection. The first magnet is embedded into the first groove in a close-fitting mode, and the surface of the first magnet is level with the end face of the first outer shell. The second magnet is embedded into the second groove in a close-fitting mode, and the surface of the second magnet is level with the end face of the second outer shell. The occlusion repair device can relieve the infection and inflammatory edema of surrounding tissue of the orificium fistulae, and repair on the orificium fistulae in the inflammatory edema and infection state is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a closure repair device for rectovaginal fistula. Background technique [0002] Currently rectovaginal fistulas rely on surgeons to repair the fistula with surgical sutures. Surgical sutures have a very low success rate of repairing the fistula, and related reports say that the recurrence rate of rectovaginal fistula surgical sutures is as high as 30%-80%. The main reasons are as follows: first, rectovaginal fistula directly contacts with human feces, which is very easy to cause infection, leading to inflammatory edema around the fistula opening and tissue brittleness; Inflammatory reaction; thirdly, feces, intestinal fluids and other pollutants containing a large amount of bacteria around the fistula can infiltrate into the tissue around the fistula along the gap between the surgical suture and the tissue, further aggravating the infection and inflammation...

Problems solved by technology

The main reasons are as follows: first, rectovaginal fistula directly contacts with human feces, which is very easy to cause infection, leading to inflammatory edema around the fistula opening and tissue brittleness; Inflammatory reaction; thirdly, feces, intestinal fluids and other pollutants containing a large amount of bacteria around the fistula can infiltrate into the tissue around the fistula along the gap between the surgical suture and the tissue, further aggravating the infection and inflammation of the tissue around the fistula. Edema

The special anatomical site of rectovaginal fistula and the disadvantages and disadvantages brought about by the surgical suture itself have seriously affected the effect of rectovaginal fistula repair surgery, and there are no related instruments and devices for the closure and repair of rectovaginal fistula
