Problems solved by technology

The former has poor anal bowel control function due to poor function of the transplanted muscles; the latter is prone to ischemia, ulcers, corrosion, infection and other problems due to the colon often being clamped, squeezed and rubbed by the artificial sphincter and pressure sensor, and also has weak defecation, Incontinence and other problems, thus limiting the wide application in clinical

Embodiment 1

[0039] figure 1 , figure 2 , image 3The shown device for simulating the function of the rectum and anal canal for defecation storage and defecation includes a rectal prosthesis 1 made of soft artificial material. Openings are provided at both ends to simulate the shape of the rectum, thus forming a tubular rectal prosthesis; clamping blocks 2 are respectively provided on both sides of the lower end of the tubular rectal prosthesis 1, wherein one clamping block is provided with a magnet 21, and the other side is provided with a magnet 21. The clamp block is provided with iron block 22 and copper coil 23. Under the normal state, the copper coil 23 is not energized, and the magnet 21 and the iron block 22 are attracted to each other so that the two clamps are moved closer together, and the lower port of the tubular rectal prosthesis is clamped and closed, as shown in FIG. figure 2 As shown; during defecation, the copper coil 23 can be energized to generate magnetic lines of...

Embodiment 2

[0047] Figure 8 , Figure 9 , Figure 10 The shown device for simulating the function of rectum and anal canal for defecation storage and defecation includes a rectal prosthesis 1 made of soft artificial material. The shape of the rectum is simulated, so a tubular rectal prosthesis is formed; there are clamps 2 on both sides of the lower end of the tubular rectal prosthesis, and there are activities to make the clamps on both sides clamp together under normal conditions and loosen during defecation Opening and closing mechanism; the movable opening and closing mechanism refers to that an elastic strip 24 applying elastic tension is connected between the clips on both sides of the tubular rectal prosthesis. The clamping blocks 2 are respectively provided with electromagnetic coils 23 , and the installation structure of the two clamping blocks 2 is the same as that of the first embodiment. Under normal conditions, the colloidal elastic tendons 24 make the two clips clamp the...

Embodiment 3

[0051] Figure 12 The shown device for simulating the function of rectum and anal canal for defecation storage and defecation includes a rectal prosthesis 1 made of soft artificial material. The shape of the rectum is simulated, so it is called a tubular rectal prosthesis; a hoop is provided at the lower end of the tubular rectal prosthesis 1 , and the fluid capsule 4 is placed between the tubular rectal prosthesis 1 and the right side 41 of the hoop. The liquid bladder block 4 communicates with the liquid pump 43 , and the liquid pump 43 is also communicated with the liquid storage bladder 44 . Under normal conditions, the liquid pump 43 pumps the liquid in the liquid storage bag 44 into the liquid bag block 4, so that the liquid bag block 4 is filled with liquid to form pressure, and the liquid bag block 4 and the left side 42 of the hoop push the tubular rectal prosthesis 1 The lower port is clamped; when it is necessary to defecate, the liquid in the liquid sac block 4 ca...

Abstract

The invention discloses a device for simulating excrement storage and discharge functions of a rectum anal tube, which comprises a tubular rectum prosthesis made of a soft artificial material. The upper end and the lower end of the tubular rectum prosthesis are provided with openings; the lower end of the tubular rectum prosthesis is provided with a movable opening-closing mechanism for controlling the opening or closing of the lower port of the tubular rectum prosthesis; and a compression mechanism for transversely compressing the tubular rectum prosthesis is arranged at the periphery of themiddle upper section of the tubular rectum prosthesis. The device can simulate the excrement storage and excrement discharge control functions of the rectum and the anal tube, and has the advantages of high simulation, no distinction from a normal person in an excrement discharge mode, strong excrement discharge, reliable, quick and flat motion, simple structure, easy manufacture, low cost and low power consumption, and capacity of avoiding the problems of ischemia, ulcer, corrosion and infection.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an artificial device for simulating the function of rectum and anal canal for defecation storage and defecation. Background technique [0002] The functions of stool storage and defecation in the human body are mainly realized by the rectum and anal canal. When the above-mentioned parts are diseased, the rectum and anal canal usually need to be removed. That is, a fistula is opened in the abdominal wall, and the stump of the colon is connected to the fistula, and an extracorporeal fecal bag needs to be installed at the position of the fistula. Although fistula has solved the problem of defecation storage and defecation, it also brings obvious inconvenience and misery to the patient. [0003] Another way is traditional in situ anal reconstruction. At present, there are two main methods: one is to pull the colon down to the anus for anastomosis, and reconstr...
