Problems solved by technology

Although thread-hanging therapy is an important method for the treatment of anal fistula, since there is no one-way thread-hanging device at present, ordinary rubber bands are used to cut the sphincter circularly, so the effect of "intestinal muscle lengthening" cannot be achieved
In addition, since the pressure during cutting cannot be controlled, the degree of tightness of the rubber band is completely controlled by the doctor during the operation, so the force on the muscle cutting is different, so the cutting time cannot be controlled

Embodiment Construction

[0008] Plate 1 can be a flat plate or a slightly curved plate, and elastic thread 2 can adopt rubber bands or other polymer elastic ropes. The plate is provided with two holes for the elastic thread to pass through, or several holes can be provided. Choose the interval for the elastic thread to pass through, the distance between the two holes for the two ends of the elastic thread to pass through is usually selected as 1-11mm, and the design of the one-way thread hanger: use the plate at the lower end of the internal sphincter and contact the plate, A flat plate or a curved plate made of plastic sheet can be used, and a plate with elasticity is better, and the thickness is about 1mm. The inner end of the sphincter uses an elastic thread. In the device of the present invention, when the pressure is equal, the pressure per unit area is inversely proportional to the area. Therefore, the pressure on one side of the thread is relatively large, and the muscles can be cut. There is v...

Abstract

A unilateral seton device for remedying the anal fistula consists of a piece of board and an elastic thread. The board is provided with holes for the two ends of the elastic thread to be put through. One end of the elastic thread which is put through the hole is provided with a bulging or a knot which is larger than the aperture, and the other end is a free end put through the hole. The free end is provided with a fixing block or a poise for frapping the elastic thread. The quite standard method and the measure of the unilateral seton treatment provided by the present invention provides the anal fistula seton therapeutics with a further development.

Description

technical field [0001] The invention relates to an operation device for treating anal fistula, in particular to a pressure-controlled thread hanger. Background technique [0002] Anal fistula is a common disease, and it is the most commonly used method to treat anal fistula by hanging thread method. An elastic rope is used in the existing hanging thread for treating anal fistula, that is, the main channel of anal fistula runs through the deep layer of the external sphincter and the pipeline above the puborectalis and the rectum. The part connected to the internal opening is hung with a rubber band, and the thread is tightened one or more times, so that the high sphincter is slowly stretched apart. And it can be tightened according to the tightness of the rubber band. Although thread-hanging therapy is an important method for the treatment of anal fistula, since there is no one-way thread-hanging device at present, ordinary rubber bands are used to cut the sphincter circular...
