Abstract

The utility model relates to a controllable sphincter artificial body which mainly consists pf a liquid capsule (1), an inversing stop valve (2), a ring-control belt (3), catheter (4) and a screw I connector (5). The liquid capsule (1) and the cyclic control belt (3) are connected into one system by the catheter (4) and inversing stop valve (2). The liquid capsule (1) is implanted into the abdominal wall; the ring control belt (3) is implanted into the intestines wall around the original anus; the inversing stop valve (2) is implanted into the scrotum of male and the labia of female. The inner carrying liquid comes and goes between the liquid capsule (1) and cyclic control belt (3) through the role of the damping force of the inversing stop valve (2). The utility model which is reliable has simple structure and long service life.

Description

Controllable type sphincter prosthese

Technical field

This utility model relates to a kind of being used in because congenital diseases, degenerative change, nerve injury or disease postoperative cause the artificial controllable type sphincter prosthese of sphincter irreversibility dysfunction, especially utilize abdominal muscle to contain liquid, by utilization damping dynamical type manual adjustment valve, make to contain liquid and travel to and fro between the liquid accumulation body between the sphincter prosthese, to replace exercising sphincter function.

Background technology

On the current social some patients owing to various complicated reasons cause urinary incontinence or since after the wound spinal cord injury cause urinary incontinence, and system or the like again of Low Rectal postoperative original position anus is all brought inconvenience in life and painful to patient.For example China's rectal cancer sickness rate is about 2/10000ths, and be cumulative year after year trend, and the rectal cancer happening part is many based on low level, account for 90% of rectal cancer, often adopt excision in order to reach the radical cure purpose, simultaneously usually hang a colostomy bag, make patient's very inconvenience in life, especially more make patient's worry summer to patient.Therefore, for many years doctor and patient all look forward to designing and developing out always a kind of operation on rectum simultaneously or postoperative implant controllable type sphincter prosthese around the intestinal wall of original position anus, to replace the sphincteral function of former anus, make patient's postoperative by its effect, still can keep defecation control function.This is that people suddenly expect, also is the task of top priority for this reason.

Summary of the invention

According to background technology, the purpose of this utility model is to provide a kind of version for utilize connection and the manual adjustment valve of built-in water pocket by conduit of performing the operation in stomach wall, make and contain liquid and travel to and fro between between water pocket and the sphincter prosthese, replace sphincter function, stop feces to be discharged when the control band is full, feces is discharged smoothly when vacant.

To achieve these goals, this utility model is achieved through the following technical solutions:

A kind of controllable type sphincter prosthese, mainly by liquid capsule (1), non-return valve (2), ring-type control band (3), conduit (4), screw socket joint (5) is formed, wherein: liquid capsule (1) is connected with conduit A (41), conduit B (42) is connected with non-return valve (2) with conduit C (43), conduit D (44) is connected with ring-type control band (3), conduit A (41) is connected with conduit B (42) by screw socket joint (5), conduit C (43) is connected with conduit D (44) by screw socket joint (5), liquid capsule (1), non-return valve (2) and ring-type control band (3) is connected to become the prosthese of a conducting through conduit (4), and its liquid capsule (1) position in human body should be higher than the position of ring-type control band (3).

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, this utility model is simple in structure, and reliable operation is used efficient and conveniently, can adjust the layout that structure is implanted in vivo at the patient of different builds and sex.

2, this utility model selects for use the long-life material generally to surpass more than 10 years.

3, this utility model is because compact conformation is simple, and it is limited to take up room, and can make the wound of implant surgery less.

4, the most effective urinary incontinence that causes owing to a variety of causes, the urinary incontinence that spinal cord injury causes after Low Rectal postoperative original position anal reconstruction and the wound, the fecal incontinence etc. of being used in of this utility model.

Description of drawings

Fig. 1 is this utility model structure collectivity schematic perspective view

Fig. 2 is the dissection sketch map of this utility model implant into body

Among the figure: 1-liquid capsule, 2-non-return valve, 3-ring-type control band, 31-plug-in unit, 4-conduit, 41-conduit A, 42-conduit B, 43-conduit C, 44-conduit D, 5-screw socket joint, 6-rectum

The specific embodiment

As shown in Figure 1, a kind of controllable type sphincter prosthese, mainly by liquid capsule 1, non-return valve 2, ring-type control is with 3, conduit 4, screw socket joint 5 is formed, and wherein: liquid capsule 1 is connected with conduit A41, and conduit B42 is connected with non-return valve 2 with conduit C43, conduit D44 is with 3 to be connected with ring-type control, conduit A41 is connected with conduit B42 by screw socket joint 5, and conduit C43 is connected with conduit D44 by screw socket joint 5, liquid capsule 1, the control of non-return valve 2 and ring-type is connected to become the prosthese of a conducting with 3 through conduit 4, and its liquid capsule 1 position in human body should be higher than ring-type control with 3 position.

Other knows, the water of packing into mostly in the liquid capsule 1, and its capacity is about 100-150ml, makes oblate cylindricality, and its maximum gauge is about 10cm.

The composition material of structure is a macromolecular material, as rubber, polyamine fat, plastics etc.

Know that again this utility model can be installed on urethra, in like manner treat urinary incontinence.

As shown in Figure 2, when being expert at radical resection of rectal carcinoma, free the leaving behind of descending colon can be placed the perineum place, liquid capsule 1 is planted in stomach wall, and its position should be higher than ring-type control and be with 3, utilizes the potential energy of liquid capsule to keep certain fluid pressure.According to patient's concrete condition, adjust size by ring-type control with 3 plug-in unit 31, ring-type control is planted around the intestinal wall of original position anus with 3 becomes an integral body with staying a rectum.

Conduit 4 implants and keeps liquid capsule 1, and non-return valve 2 is connected with the conducting that ring-type is controlled with 3.

Non-return valve 2 is implanted in the scrotum for the male, implants in the labia for the women.

Other knows, generally speaking, ring-type control is with 3 to be in the discharge of topping up state prevention feces, if want defecation, available hands is to non-return valve 2 pressurizations, make its distortion, cause the pressure reduction of conduit 43 and conduit 42, suck ring-type control and be with part flow direction liquid capsule 1 in 3, it is hollow that ring-type control is with in 3, it is big that the endless belt internal diameter becomes, thereby can defecation or urinate.By the damping dynamic action of non-return valve 2, can make to contain liquid and travel to and fro between the control of liquid capsule 1 and ring-type and be with between 3.
