Anal fistula oriented seton stringing device

Abstract

The invention discloses an anal fistula oriented seton stringing device. The anal fistula oriented seton stringing device comprises a seton device body, a traction part, a drainage thread, and a drainage thread stringing device, wherein the center of the seton device body is provided with a guide hole, and one end of the seton device body is provided with a nose-shape bending part; the traction part is arranged in the guide hole, one end of the traction part is provided with a drainage thread locating lug, and the other end of the traction part is provided with a releasing ring; the drainage thread is connected with the drainage thread locating lug; the drainage thread stringing device comprises a seton plate and a stringing fastener. The anal fistula oriented seton stringing device is characterized in that the center of the stringing fastener is provided with a drainage thread clamping hole, a drainage thread stringing hole penetrates through the stringing fastener in the lengthwise direction, a self-closing expansive groove is formed in the stringing fastener, the self-closing expansive groove is communicated with the drainage thread clamping hole, the self-closing expansive groove clamps the drainage thread which penetrates through the drainage thread clamping hole in the drainage thread clamping hole, and a stringing fastener large-head section is arranged on the outer wall of the end, away from the seton plate, of the stringing fastener. The working intensity of a surgery doctor is relieved, the operation time is shortened, and the expected stringing effect is guaranteed; normal operation of anal fistula incision is guaranteed; the trauma surface of the anal opening is assured to be clean; a stepless stringing effect is embodied.

Description

technical field [0001] The invention belongs to the technical field of medical surgical instruments, and in particular relates to a directional thread tightening device for anal fistula, which is a thread-hanging and thread-tightening device for the anorectal ring that needs to be drained or strangulated in the treatment of high perianal abscess and high anal fistula. Surgical equipment for wire processing. Background technique [0002] A fistula is a tube formed when an abscess occurs in a human or animal body. The tube opens or communicates with other internal organs on the surface of the skin, and the secretions in the lesion can overflow through the fistula. Anal fistula is one of the difficult diseases in the field of anorectal surgery. For the above-mentioned high perianal abscess and high anal fistula surgery, not only the surgeon (surgeon) is required to have good skills, but also requires rich surgical experience. , Scholars at home and abroad have devoted a lot of...

Problems solved by technology

[0005] But the aforementioned CN101642381B still has the following shortcomings: one, because the tightening buckle of the structural system of the wire tensioner (the patent is called "drainage wire standard tightening device") does not have elastic closing force, it cannot be changed by its own elasticity such as when closing. Tighten (or clamp) the drainage wire, so after the drainage wire passes through the wire tightener, the surgeon needs to tie a knot at the end of the drainage wire (that is, "anal fistula secant line", the same below), so on the one hand, increase It reduces the work intensity of the surgeon, on the other hand prolongs the operation time, and on the one hand, because of the difference between the position of the knot and the degree of tightness that is actually expected, it affects the strangulation effect on the anal fistula; The knot at the end may be loosened, so once it is loosened, it will inevitably lead to the failure of the tight thread, which will affect the directional strangulation, and even need to re-hang the thread to tighten the thread, which will increase the pain for the patient; third, due to the tight thread stuck Buckle is easy to accumulate feces (feces) and is not conducive to cleaning, so it is very easy to cause infection on the wound; Fourth, because the end of the drainage line is positioned by knotting, it cannot satisfy any degree of stepless adjustment of the drainage line In particular, it is difficult or even impossible for the recipient to tighten the thread independently. However, in the actual treatment of anal fistula, the effect of adjusting the drainage thread according to the patient's own feeling is far better than that adjusted by the surgeon.
