Description

Anal fistula thread-hanging device

Technical Field

The disclosure relates to the field of medical instruments, in particular to an anal fistula seton device.

Background

Anal fistula is a short term for anorectal fistula and is a residual lesion caused by abscess rupture or incision drainage around the anorectum. Anal fistula is a post-abscess age and is two stages of disease. The name of English is Anal fistula, called Anal fistula in traditional Chinese medicine. Anal fistulas are typically a clear, intact canal that runs from one end in the anal sinus to the other end outside the anal margin, or in the rectal wall. Atypical anal fistula generally has only an inner orifice but no outer orifice, or has an inner orifice but an outer orifice, but the middle fistula is occluded, or has only an outer orifice, and the inner orifice can not be found, or is only a induration if the fistula is dry.

Seton is a common treatment for anal fistulas. The method for treating anal fistula by utilizing the tight binding of silk threads or rubber bands and blunt and slow dissection of the pipeline by mechanical pressure or contractility is simple, convenient and economic, does not influence the anal function, and has the advantages of small scar, smooth drainage and the like.

The hanging thread is suitable for high anal fistula with the fistula exceeding the anal straight ring, and can obviously touch the rope-shaped tube wall clinically without branches. To protect sphincter function, a sling therapy is used. However, the crossing of the anal sphincter is difficult, the threading and the thread hanging are not easy, and a plurality of threads are difficult to hang at one time.

Anal fistula is a short term for anorectal fistula and is a residual lesion caused by abscess rupture or incision drainage around the anorectum. Anal fistula is a post-abscess age and is two stages of disease. The name of English is Anal fistula, called Anal fistula in traditional Chinese medicine. Anal fistulas are typically a clear, intact canal that runs from one end in the anal sinus to the other end outside the anal margin, or in the rectal wall. Atypical anal fistula generally has only an inner orifice but no outer orifice, or has an inner orifice but an outer orifice, but the middle fistula is occluded, or has only an outer orifice, and the inner orifice can not be found, or is only a induration if the fistula is dry.

Seton is a common treatment for anal fistulas. The method for treating anal fistula by utilizing the tight binding of silk threads or rubber bands and blunt and slow dissection of the pipeline by mechanical pressure or contractility is simple, convenient and economic, does not influence the anal function, and has the advantages of small scar, smooth drainage and the like.

The hanging thread is suitable for high anal fistula with the fistula exceeding the anal straight ring, and can obviously touch the rope-shaped tube wall clinically without branches. To protect sphincter function, a sling therapy is used. But the penetration of the anal sphincter is difficult, the threading and the thread hanging are not easy, and a plurality of threads are difficult to hang at one time.

Fig. 1 shows a schematic structural view of an anal fistula seton device according to an embodiment of the present disclosure.

As shown in fig. 1, the anal fistula seton device 100 comprises a handle body 101, a blunt end 103 and a seton 102. The blunt end 103 is disposed at a first end of the handle 101, and the wire-hanging portion 102 is disposed at a second end of the handle 101. The blunt end 103 prevents injury to the patient during the threading procedure.

Fig. 2 illustrates a schematic structural view of a hanging portion according to an embodiment of the present disclosure.

Specifically, fig. 2 shows a specific structure of the wire hanging portion 102 in fig. 1.

The hanging wire part 102 includes: a first portion 201 and a second portion 202.

The first end of the first portion 201 is fixedly connected to and integrally formed with the first end of the handle body. A first end of the second portion 202 is fixedly connected and integrally formed with a second end of the first portion 201. The first portion 201 and the second portion 202 enclose a line-containing space 203. The width of the first opening 204 between the first end of the first part 201 and the second end of the second part 202 is smaller than the width of the wire accommodating space 203, so that the wire can be conveniently fed into the wire accommodating space 203 from the first opening 204, and the wire can be well fixed in the wire accommodating space 203 in the wire hanging process, and can be prevented from falling off.

Due to the first opening 204, the thread containing space 203 is not completely closed, and the thread can be conveniently hung into the thread containing space 203 from the hanging first opening 204 without complicated threading.

In the disclosed embodiment, the second end of the second portion 202 includes: a first blocking tooth 205 to block the wire from escaping from the wire space 203.

In the disclosed embodiment, the anal fistula seton device 100 further comprises a second arresting tooth 205, and the second arresting tooth 205 is fixedly connected with and integrally formed with the first end of the handle body. A second opening 206 is defined between the second blocking tooth 205 and the second end of the second portion to facilitate feeding of the thread.

The anal fistula seton device 100 adopts the seton part 102 as shown in fig. 2, a plurality of wires or thicker wires can be put in at one time, and the defect that the traditional seton device has a closed wire accommodating space and can only penetrate 1 thin wire is avoided.

In the disclosed embodiment, as shown in FIG. 1, the blunt end 103 is spherical to prevent injury to the patient. The handle body 101 is an arc-shaped handle body.

Fig. 3 shows a schematic structural view of an anal fistula seton device according to another embodiment of the disclosure.

In particular, fig. 3 shows another embodiment of an anal fistula seton device that differs somewhat from fig. 1.

As shown in fig. 3, the anal fistula seton device 300 comprises a handle 301, a blunt end 303 and a seton 302. The blunt end 303 is disposed at a first end of the handle body 301, and the wire-hanging portion 302 is disposed at a second end of the handle body 101.

Fig. 4 illustrates a schematic structural view of a hanging portion according to another embodiment of the present disclosure.

In the embodiment of the present disclosure, the wire hanging portion 302 includes: a first hanging wire portion 401 and a second hanging wire portion 402. The first hanging wire portion 401 and the second hanging wire portion 402 are fixedly connected to the first end of the handle body 301 and are integrally formed. The first hanging wire portion 401 and the second hanging wire portion 402 form a third opening 403, and the third opening 403 communicates with the first opening 404 and the wire accommodating space 405.

As shown in fig. 4, a second portion of the first hanging wire portion 401 and a second portion of the second hanging wire portion 402 face each other, and a third opening 403 is formed in a gap therebetween. The first opening of the first hanging wire portion 401 and the first opening of the second hanging wire portion 402 are opposed to each other and both communicate with the third opening 403.

After the middle section of the wire is inserted from the third opening 403, the wire accommodating space of the first hanging wire part 401 or the second hanging wire part 402 can be accessed through the first opening. A plurality of wires may be inserted into the third opening 403 to be inserted into the wire accommodating spaces of the first and second hanging wire parts 401 and 402, thereby increasing the wire accommodating amount of the anal fistula hanging wire device 300.
