Description

A kind of dystopy implanted artificial anus leakproof excrement replacement device

Technical field

The utility model belongs to bioengineering field, and in particular to a kind of medical artificial organ.It is suitable more particularly, to one kind For the dystopy implanted artificial anus leakproof excrement replacement device of full anal resection patient.

Background technology

Artificial anus's finger pulp portion intestines stoma（Intestine fistulization）, i.e., stool discharge is made to change its course by operation, abdominal stoma（Fistulization） To the outlet to void excreta.After being more common in radical rectal excision, the interim stoma of post operative colo-rectal cancer, intestinal obstruction patient be Release bowel obstruction etc..

Artificial anus's shortcoming is to be located at human abdomen, is not easy common problem encountered is that surgical wound surface is injured caused by skin Restore, infection rate is high, and postoperative care is complicated.Excrement and usually excessive pollution skin, and the peculiar smell of excrement, also enable patient Discomfort influences patient's social activities；Increase the psychological burden of patient, reduce patients ' life quality.In addition, since artificial anus needs It to be adapted to according to the size of patient's rectum, so need to be open to artificial anus according to rectum size, current operation side Method is that the opening of rectum size is directly cut according to patient's experience, therefore influences the installation of later stage artificial anus.

The ostomy appliance of artificial anus（Patent No. CN205234738U）Patent, though make it can be with by adjusting blade position Freely adjust the openings of sizes of artificial anus；But method is complicated, and easily infection etc. is real there are still leakage excrement, gas leakage and fistulization oral Border problem；The obturator of another prevention fecal pollution surface of a wound and skin（Patent No. CN204543012U）Patent, pass through by Expanse closing drainage circle compressing inner wall of intestine in device merging enteron aisle, and closed stabilization is kept, but lack in compressing enteron aisle Wall blood flow monitors, and there are medical security risks.

Invention content

The utility model is in view of the above-mentioned problems of the prior art, and provide a kind of dystopy implanted artificial anus leakproof Excrement replacement device.The replacement device is the stoma replacement device production using a kind of artificial anus of tissue engineering technique design Product, to solve the problems, such as current artificial anus's opening leakiness excrement, the nonstandard difficult formulation of openings of sizes.

Technical solutions of the utility model are as follows：

A kind of dystopy implanted artificial anus leakproof excrement replacement device, feature include agent structure and external knot at it Structure, wherein, agent structure into excrement connecting tube and fixed inner ring by forming, and fixed inner ring into one end of excrement connecting tube with fixing Connection；External structure is formed by fixing outer shroud and storage stool bag, and fixed outer shroud is fixedly connected with storing up the upper end of stool bag, stores up excrement Bag is equipped with excrement amount visual window, and fixed inner ring is correspondingly arranged with fixed outer shroud.

The fixed inner ring and the shape of fixed outer shroud are circle, fixed annular diameters ranging from 2.5-4.5cm；Thickness Ranging from 0.3-0.6cm, fixed outer annular diameter ranging from 2.8-4.8cm, thickness range 0.4- corresponding with fixed inner ring 0.8cm。

Described to implant into excrement connecting tube and fixed inner ring, the other end and intestinal tube into excrement connecting tube pass through suture Mode is coincide connection, and fixed outer shroud and fixed inner ring are in the corresponding connected tight connecting of snap ring-type.

The fixed outer shroud and fixed inner ring are using the correspondings connected tight connecting of concave-convex buckle spline structure.

It is described to be made into excrement connecting tube and fixed inner ring of chlorine tetrafluoroethene through three D printing techniques, it implants and intestines Pipe seam closes the latter two tight connectings, has leakproof excrement, substitutes the function of nature anus.

The utility model advantage and effect：

1. solve excrement change its course or anus reconstruction operation after stool bag leakage excrement, gas leakage, influence patient's social activities, bring FAQs and patient mental and the psychological problems such as infection, excrement spill and leakage；

2. being monitored using excrement input visual window, cooperation agent structure understands the storage excrement amount in storage stool bag, has Imitate the process that the excrement of simulation straightened natural intestine enters；

3. carrying out the connection that coincide using agent structure and intestine suture mode, patient is made to be in which kind of posture position all Excrement can be made smoothly to enter storage stool bag.
