Embodiment 1

[0042] Please see attached figure 1 , with figure 1 It is a cut-away schematic diagram of each part of an anal fistula hanging thread drainage tube which is convenient for ligation and metering according to the present invention. A line drainage tube for anal fistula that is convenient for ligation and metering, including a drainage tube 1, a snare 2, an upper ring thimble 3, an auxiliary upper ring device 4, and two rubber rings 5; please refer to the attached figure 2 , with figure 2It is a three-dimensional schematic diagram of drainage tubes of several specifications described in the invention, which is convenient for ligation and metering. The drainage tube 1 is a hose structure made of medical latex material with scale marks on the surface, and the two ends of the drainage tube 1 are rounded and chamfered to avoid damage to the skin it passes through when passing through the fistula tract , its specifications are solid hoses with diameters of 2mm and 3.5mm and hollo...

Embodiment 2

[0046] Please see attached Figure 9 , with Figure 9 It is a schematic diagram of the process of connecting the rubber ring to the snare of another anal fistula hanging thread drainage tube that is convenient for ligation and metering in the present invention. An anal fistula hanging wire drainage tube that is convenient for ligation and metering includes a drainage tube 1 (not shown in the figure), a snare 2, an upper ring thimble 3, an auxiliary upper ring device 4, and a rubber ring 5; the drainage tube 1 is The hose structure with graduated marks on the surface is made of medical latex material. The two ends of the drainage tube 1 are rounded and chamfered to avoid damage to the skin it passes through when passing through the fistula tract. Its specification is 2mm in diameter. , 3.5mm solid hose and hollow hoses with diameters of 5mm and 7mm, and the wall thickness of the hollow hose is 2mm; the midpoint of the drainage tube 1 is set to zero scale, and from the zero sca...

Embodiment 3

[0048] Please see attached Figure 10 , with Figure 10 It is another three-dimensional schematic diagram of the snare described in the anal fistula hanging wire drainage tube which is convenient for ligation and metering in the present invention. Embodiment 3 is basically the same as Embodiment 1, except that both ends of the snare 2 are provided with loop segments 21 . The increase in the number of the loop segments 21 does not affect the use effect of the present invention, and both ends of the snare 2 can be inserted into the rubber ring 5 (not shown in the figure), which increases the flexibility of use.

Abstract

The invention belongs to the technical field of medical instruments, and relates to an anal fistula seton drainage tube convenient to ligature and measurement. The anal fistula seton drainage tube comprises a drainage tube, a snare, an upper ring thimble, an auxiliary ring feeder and a rubber ring, the drainage tube is a plurality of hoses with scales; the snare is of a hollow tubular structure and is provided with a ferrule section and a clamping section. The ferrule section is used for sleeving the rubber ring with an enlarged opening, so that ligation is facilitated; a groove is formed in the cylindrical surface of the clamping section, and a through hole is formed by the clamping section and the internal hollow structure; the inner diameter of the clamping section is greater than thatof the ferrule section; the upper ring thimble is composed of a connector and a conical structure; the connector is detachably connected with the ferrule section; the auxiliary ring feeder comprises aholding section and a pushing section; the holding section is of a cylinder structure, so that force application and propulsion are facilitated; a stop ring is arranged at lower end of pushing section, and the upper end part of the pushing section is fixedly connected with the holding section. The anal fistula seton drainage tube has the advantages that the anal fistula seton drainage tube has various specifications, is suitable for different illness states respectively, high in specificity and functionality, durable in material, and convenient to ligature and simple and convenient in subsequent ligature operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a line-hanging drainage tube for anal fistula which is convenient for ligation and measurement. Background technique [0002] Anal fistula is a common intractable disease in surgery. Most low anal fistulas can be cured by incision or excision. Due to its anatomical characteristics, simple incision of high complex anal fistula will damage the anal sphincter and cause anal incontinence. The thread-hanging drainage treatment can not only protect the anal sphincter, but also has a small postoperative scar and smooth drainage. It is one of the most traditional and convenient surgical methods for complex anal fistula. Thread-set drainage is currently mainly used for short-term drainage of complex anal fistula and high horseshoe fistula, and it is also particularly effective for long-term drainage of anal fistula secondary to Crohn's disease and AIDS. [0003] At present, the...
