Embodiment
As shown in Figures 1 to 4, the endoscope-assistant surgery single-hole multi-channel road in this programme enters device, including connection ring 1, even
Connect ring 1 and be provided with incision protective sleeve docking structure 2, be provided with flexible seal cover 3 in one end of connection ring 1, flexible seal cover 3 is not
In the flexible convex closure 4 for protruding from the outer face of connection ring 1 or when the inner side of flexible seal cover 3 is in barotropic state when being acted on by external force
When flexible seal cover 3 be in protrude from the flexible convex closure 4 of the outer face of connection ring 1, if flexible convex closure 4 is provided with dry passage 5, passage 5
It is made up of film elastic material.
This programme on flexible seal cover 3 by setting the passage 4 passed through for apparatus so that apparatus can be with passage one
Same flexible rotating, and the angle rotated is larger, is easy to the operation of operation to carry out.
And incision protective sleeve docking structure 2 includes the annular snap groove 13 for being arranged on the inwall of connection ring 1, annular snap groove
13 shape is adapted with the ring body 15 of incision protective sleeve 14.Ring body and the annular snap groove in connection ring need to only be matched somebody with somebody during assembling
Close installation, enable to passway to enter both device and incision protective sleeve and quickly be connected, and both assemble and consolidate, be not easy to take off
Fall.
Specifically, flexible seal cover 3 includes cylindrical portion 6, and one end of cylindrical portion 6 is opening end, and the other end is blind end
7, opening end is connected with one end of connection ring 1, and passage 5 is arranged on the blind end 7 of cylindrical portion 6 or the sidepiece of cylindrical portion 6.Closing
7 are held curved to arch upward.
In one of the embodiments, above-mentioned flexible seal cover 3 is outer without departing from connection ring 1 when not acted on by external force
End face, the scope of activities of the operating theater instruments in the embodiment are smaller.
In another embodiment, flexible seal cover 3 is in plane and parallel to the outer face of connection ring 1, and when flexible close
Flexible seal cover 3 is in the flexible convex closure 4 for protruding from the outer face of connection ring 1 when the inner side of sealing cover 3 is in barotropic state.In such scheme
In, flexible seal cover 3 flushes in unaerated in relaxed state or with the outer face of connection ring 1, when in flexible seal cover 3
During inflation, flexible seal cover 3 is just heaved and protrudes from the outer face of connection ring 1, and the projection of flexible seal cover 3 can be further
The flexible movement for the apparatus being fixed in passage 5 is improved, and flushed relative to flexible seal cover 3 with the outer face of connection ring 1
In the case of, during the projection of flexible seal cover 3, the rotational angle of apparatus is bigger, and operating space is also bigger.

Specifically, seal 8 includes any one in valve, a word seal, cross seal.In order to improve dress
Overall air-tightness is put, prevents gas leakage, seal 8 is connected as a single entity with passage 5；Or seal 8 is set independently of passage 5
And seal 8 is fixed in passage 5.
In order to prevent sleeve pipe from departing from passage 5, the sleeve pipe of puncture outfit is provided with least one bulge loop 9, and works as sleeve pipe
20 at least one bulge loop 9 when inserting in passage 5 cross the Inner ports of passage 5, to be preferably fitted close both.
Passage 5 in this programme includes at least one endoscope insertion passage 51 and at least two operating theater instruments insertion passage
52.Passage 5 also includes at least one reserved passageway 21 for being closed or opening.The reserved passageway 41 is when not in use in envelope
Closed state, closed state can a knot be beaten on reserved passageway or by the way of clamping closure by the upper of reserved passageway 41
End seal is closed, to prevent gas leakage.
In addition, connection ring 1 or flexible seal cover 3 are provided with least two air pipe sleeves 10, worn in one of air pipe sleeve 10
Provided with air inlet pipe 11, escape pipe 12 is equipped with another air pipe sleeve 10.Air pipe sleeve 10, connection ring 1, flexible seal cover 3 and logical
Road 5 is made by elastomeric material, and the thickness of connection ring 1 is more than the thickness of air pipe sleeve 10, and air pipe sleeve 10, connection ring 1, flexibility are close
Sealing cover 3 and passage 5 are made into integration.
The gas for causing to enter to prevent escape pipe and air inlet pipe to be located at sustained height is expelled directly out, in this programme
The Inner ends of escape pipe 12 extend in connection ring 1 so that the Inner ends of escape pipe 12 are less than the Inner ends of air inlet pipe 11.Air inlet simultaneously
Pipe 11 is provided with opening/closing control structure, and escape pipe 12 is provided with opening/closing control structure.
As shown in figure 5, in another embodiment, incision protective sleeve docking structure 2 includes the ring for being arranged on the inwall of connection ring 1
Shape step 16, at least two buckles 17 are hinged with connection ring 1, and buckle 17 is provided with the arc clamp positioned at the lower section of connection ring 1
18, the located space 19 of the ring body 15 of polarizing slot protective case 14 is formed between arc clamp 18 and connection ring 1.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
Although connection ring 1, incision protective sleeve docking structure 2, flexible seal cover 3, flexible convex closure have more been used herein
4th, passage 5, cylindrical portion 6, blind end 7, seal 8, bulge loop 9, air pipe sleeve 10, air inlet pipe 11, escape pipe 12, annular snap groove
13rd, incision protective sleeve 14, ring body 15, ring-shaped step 16, buckle 17, arc clamp 18, located space 19, sleeve pipe 20, reserved logical
The grade term of road 21, but it is not precluded from the possibility using other terms.It is used for the purpose of more easily describing using these terms
With the essence for explaining the present invention, it is construed as any additional limitation and is all disagreed with spirit of the present invention.
