[specific embodiment]

Below in conjunction with accompanying drawing the present invention is described further, the structure of this device and principle are very clearly concerning this professional people.

As shown in the figure, the present invention is made up of disposable intestinal mirror trocar sheath and supporting apparatus two parts, comprises the plastic film tube of a transparent sealing of front end, is complete transparent plastic foil; Front end hyaline membrane (1) is circular, and the external diameter of plastic film tube is φ 15mm, plastic sheeting length of tube 600mm; Two A/Cs in the plastic film tube outside, one is internal diameter φ 2mm, the conduit (4) of external diameter φ 4mm; Another root is internal diameter 3mm, the conduit of external diameter 5mm (3), and the length of two conduits is 800mm; Two conduits are connected as a single entity with plastic film tube and do not communicate at front end, ovalize three chamber trocar sheaths, and this trocar sheath is disposable products.

The supporting apparatus of the present invention mainly is made up of aqueous vapor gauge tap and connecting duct; Its unitary construction is: the plastic film tube of the transparent sealing of front end, in its outside two A/Cs that are connected as a single entity with plastic film tube are arranged, and a conduit is connected with suction device; A conduit is connected with the aqueous vapor gauge tap of supporting apparatus; The aqueous vapor gauge tap other end inserts an air induction conduit and a penstock, and the external diameter of gauge tap aqueous vapor extraction catheter (11) is φ 5mm, and the external diameter of air induction conduit (12) is φ 5mm; The external diameter of penstock (13) is φ 5mm, regulates in turn through the aqueous vapor gauge tap and send water or supply gas.Plastic film tube (2) is inserted in to hyaline membrane (1) from the intestinal camera end fully; One of which side conduit (3) is connected to suction pump with negative pressure catheter (5); Opposite side conduit (4) be connected with gauge tap aqueous vapor extraction catheter (11) at front end with the gauge tap (7) that is fixed on the intestinal mirror; One of gauge tap (7) rear end is connected with gauge tap air induction conduit (12), and this conduit connects air pump; Another root is connected with gauge tap penstock (13), and this conduit connects the water source.

Aqueous vapor gauge tap: comprise housing, axle center and knob three parts composition; So-called housing is a hollow cylinder of sealing up and down, and the circular hole (11,12,13) of three same horizontal planes is arranged at its middle part, side, and three circular holes all with in the housing communicate and have conduit to draw, and are as shown in Figure 3; The line ofcircular hole 11,13 is through the cylindrical center of circle, andcircular hole 12 is connected with the center of circle, and the acute angle angle that forms withcircular hole 11,13 lines is α, and is as shown in Figure 5, is the housing cross-sectional view; What be complementary with the housing inboard is 3/4 cylindrical axle center, and promptly the column type axle center all has one 90 ° breach from top to bottom, and there is atubule 18 in axle center central authorities along the longitudinal axis, and the upper end communicates with the external world throughrotary switch 19, theangle 17 of lower ending opening 90 ° of breach in the axle center.See Fig. 4; One Y-type three way type pipe is arranged on this axle center cross section, and opening is that 14 pipeline is positioned at column type breach edge, and extends to the offside in axle center; Formation is opened on 15 pipeline; Be opened on pipeline the same side of 15, another pipeline becomes the α angle with it and at grade along stretching out the axle center, forms to be opened on 16 pipeline; See Fig. 6, be the axle center cross-sectional view; After housing was inserted in the axle center, tee T and housing three circular holes were positioned at same horizontal plane, see Fig. 7, for being inserted in sketch map behind the housing in the axle center; The outerrotary switch 19 of housing is connected with the axle center, and axis of rotation rotates axle center pipeline opening 14 between housingcircular hole 12 andcircular hole 13; Alternately connect with it; Through axle center pipeline opening 15 or 16, water or pneumatic transmission are reached housingcircular hole 11 places, reach the purpose of aerofluxus or draining.

Concrete operations flow process of the present invention is following:

1. the intestinal mirror is connected with main frame, and the water filling gas injection shift knob of the operating portion of intestinal mirror own is extracted.Make the no aqueous vapor injection state that is in.

2. be that the disposable oval trocar sheath (2) of 600m is inserted in from the intestinal camera end fully with length.Film tube both sides conduit; Internal diameter φ 3mm conduit (3) is connected to suction pump, and internal diameter φ 2mm conduit (4) is connected to gauge tap, behind the gauge tap; A conduit (12) is connected with the air pump of intestinal mirror main frame, and a conduit (13) is connected with the cleaning water source that has certain pressure.

3. the intestinal mirror that will be with trocar sheath inserts anus, utilizes the camera system and its adjusting of knob all around of intestinal mirror, sees through the hyaline membrane of sleeve pipe head end; The enteric cavity mucosa is observed; Because it is long that rectum is generally 120-150mm, and the disposable external-cover pipe has 600mm long, so from the degree of depth; Except that mucous membrane of rectum is observed, the Sigmoidocolic inspection of part also will become possibility.

4. in the checking process, the conduit (4) through sleeve pipe one side 2mm internal diameter injects certain gas, makes the enteric cavity expansion be convenient to observe, and if any a small amount of feces, this conduit capable of using injects the water flushing of certain pressure, and enteric cavity is got a clear view; Conduit (3) the vacuum suction enteric cavity liquid of another φ 3mm internal diameter of while, unnecessary liquid and excrement matter are eliminated those who are investigated's sense of discomfort to alleviate enteric cavity pressure in the eliminating enteric cavity; This conduit (3) also can be used as the use of biopsy pipeline when finding pathological changes, inserts biopsy forceps clamp tissue from the connecting portion front end, to send pathologic finding.

5. patient of every inspection changes trocar sheath one time, prevents cross infection, has reduced the program of common intestinal mirror cleaning and sterilizing, adds that microscopic examination of rectum inspection required time own is not long, has more saved great amount of time, can be used for general survey conscientiously.
