Abstract

The original position artificial anus controller is installed in the inner chamber of artificial anal pouch.It has two centrosymmetric intermediate plates, promotes through operating mechanism, can make intermediate plate around its fulcrum clockwise or rotate counterclockwise, thereby intermediate plate is unclamped or clamps anus utricule lower tubular section.The patient only need press and be contained in the subcutaneous key switch of femoribus internus, i.e. may command defecation or gather feces.The shape of the complete simulating nature rectum anal tube of the shape section when moving with the original position artificial anus of sort controller control, defecation is handled convenient, clamps rationally reliably, is specially adapted to the patient that anal function is rebuild ability and oldaged physically weak.

Description

The invention belongs to artificial organ, relate to artificial anus's feces control device.

The application number of the applicant's application is 92104227.2, name is called the patent of invention of " artificial anal pouch and installation method thereof ", a kind of artificial anal pouch is provided, its internal ring wall has shrinkage expansion and pressure controlled function, make the intravital intestines section of capsule feces gather or physiological movement such as defecation shrinkage expansion in obtain utricule and support and help, make the patient rebulid the basic function of nature anus gradually, especially to the intestinal function good patient, effect is tangible.But for old or the not good patient of intestinal function, this artificial anal pouch is difficult to satisfy the defecation requirement, promptly can not satisfy the requirement that feces gathers or the defecation shrinkage expansion moves fully.

Task of the present invention provides above-mentioned artificial anus's feces controller, and control original position artificial anal pouch is to be suitable for different body constitution patients' requirement, and this device is loaded in the inner chamber of artificial anal pouch.The patient operates this controller can make the smooth closure or openness of artificial anus, reaches the purpose that control defecation or feces gather.

The basic scheme and the operation principle thereof of artificial anus controller are as follows: controller is installed in the inner chamber between the artificial anal pouch pipe section inside and outside wall of above-mentioned patent application (92104227.2).Construction features be centrosymmetry two identical intermediate plates are housed, the patient can utilize operating mechanism to make two intermediate plates around fulcrum clockwise or rotate counterclockwise on demand, two intermediate plates can make artificial anal pouch bottom pipe section internal ring wall become relaxed state or clamped condition, and the realization patient controls defecation or gathers the function of feces.

Description of drawings:

Fig. 1 is the structural representation of artificial anus controller.

Fig. 2 is the AOO ' A cutaway view of Fig. 1, and for ease of analyzing, the right clamping piece 5 that is cutd open still is shown among the figure.Be illustrated as the opening of controller, promptly artificial anal pouch bottom pipe section internal ring wall is in relaxed state.

Fig. 3 is the AOO ' A cutaway view of controller Fig. 1 when being closure state.

Describe organization plan in detail with reference to accompanying drawing:

As shown in Figure 2, described operating mechanism has action bars 8, and its front end and straight pin 17 are hinged, and the rear end leads to as shown in Figure 1 that artificial anal pouch is outside fixedlys connected with the kinematic axis of key switch 9; Straight pin 17 is fixedly mounted on the swivel becket 1 that is press-fitted with ball bearing 2 inner rings, and the inner headed face of the outer ring of ball bearing 2 and cylinder stent 3 is press-fitted, and the cylindrical of cylinder stent 3 matches with the interior circle of artificial anal pouch 11 pipe section external annulus; There is retainer ring 4 ball bearing 2 tops, it and ball bearing outer ring near, and be fixed into one with cylinder stent 3 inner headed faces; But swivel becket 1 rotates with bearing inner race relative fixed ring 4 and cylinder stent 3; One group of straight pin 12 and 13 are installed in centrosymmetry ground respectively on retainer ring 4 and swivel becket 1; Two intermediate plates 5 are positioned at retainer ring and swivel becket top, are similar to annular angle bar, aperture 12 on the intermediate plate ' join with straight pin 12 cunnings as the intermediate plate fulcrum, and straight pin 13 can slide in the slotted hole groove 14 on intermediate plate.Action bars 8, key switch 9 and kinematic axis integral installation thereof in vivo, key switch is positioned at the subcutaneous of femoribus internus position.Action bars and key switch are by 10 sealings of medical grade silicon rubber overcoat, overcoat 10 and anus utricule 11 junction adhesive sealings.Support with cylinder lining 7 in that anus utricule Taper Pipe section external annulus is inboard, it can improve the rigidity of anus utricule external annulus with cylinder stent 3.Cylinder props up folder joins for face of cylinder cunning and is nested with lining, and circular thin slice cover plate 6 is equipped with in the centre of its junction, and cover plate and cylinder stent 3 are fixed with pressure.Cover plate and two intermediate plate upper surface cunnings are joined, play up and down not when intermediate plate is rotated, and blister cavities is divided into upper and lower two parts.

The operation principle of controller: when two intermediate plates 5 were in clamping (closure) state, utricule bottom pipe section internal ring wall was clamped distortion by intermediate plate, as shown in Figure 3.Be rolled in the also clamped distortion of intestines section in the utricule pipe section internal ring wall, its shape and the human body natural's anal canal shape when closure state is similar; When two intermediate plates 5 were in lax (opening) state, utricule pipe section internal ring wall and the intestines section of being wrapped up thereof also were in lax free state (as shown in Figure 2), and under the pressure effect that enteral pressure and diaphragm press down, feces excretes.
