Specific embodiment
As shown in Figure 1, Figure 3, the endoscope-assistant surgery single-hole multi-channel road in this programme enters the connection structure of device and puncture outfit,
It is characterised in that it includes endoscope-assistant surgery single-hole multi-channel road enters the channel 4 of device and the casing 12 of puncture outfit, channel 4 is in a tubular form
And be made of elastic material, casing 12 inserts in 12 outer wall of rear sleeve and 4 inner wall circumferential seal of channel in channel 4 and cooperates.Channel 4 by
Film elastic material is made, and 4 internal diameter of channel is less than 12 outer diameter of casing and set is tightly attached in channel 4 when casing 12 inserts in channel 4
12 outer wall of pipe.
In order to enable the casing of puncture outfit is inserted into channel 4, channel 4 is made of film elastic material, channel 4 it is interior
Diameter is less than the sleeve outer for inserting in puncture outfit therein and forms axial direction between the two when the casing of puncture outfit inserts in channel 4
Positioning and circumferential seal.Since channel 4 has certain elasticity, can fit closely to form sealing with the casing of puncture outfit.
As shown in Fig. 2, the casing 12 being inserted into order to prevent is detached from channel 4 in use, set on casing 12
There is disconnecting prevention structure 13.Disconnecting prevention structure 13 includes the bulge loop 14 that at least one is set on casing 12, and when casing 12 inserts in channel 4
When at least one bulge loop 14 cross 4 inner port of channel.Cross 4 inner port of channel and the bulge loop 14 adjacent with 4 inner port of channel
End face is plugged in 4 inner port periphery of channel.
After casing 12 is inserted into 4 inside of channel, the bulge loop 14 of 12 lower end of casing is located at the outside of 4 inner port of channel and will lead to
4 inner port of road is sealed, and since channel 4 is made of elastic material, the two is capable of forming good sealing performance.
It includes connection ring 1 that endoscope-assistant surgery single-hole multi-channel road in this programme, which enters device, and notch is equipped in connection ring 1 and is protected
Sheath docking structure 2 is equipped with flexible seal cover 3 in one end of connection ring 1, and channel 4 is set on flexible seal cover 3 and channel 4
Quantity is no less than three.By the way that the channel 4 passed through for instrument is arranged on flexible seal cover 3, enable instrument with channel
Flexible rotating together, and the angle rotated is larger, carries out convenient for the operation of operation.
In order to improve the sealing performance of device, channel 4 and flexible seal cover 3 are made of film elastic material and the two one
It is body formed.
Channel 4 includes that at least one endoscope insertion channel 41 and at least two instruments are inserted into channel 42；Channel 4 further includes
At least one reserved channel 43 that can be closed or open, the reserved channel 41 are in closed state, closed when not in use
State can be to beat on reserved channel and tie or by the way of clamping closure by the upper end closed in reserved channel 41, with to prevent
Leak-stopping gas.
Since connection ring 1 needs to be coupled with the ring body on incision protective sleeve 11, the thickness of connection ring 1 is greater than soft
Property seal closure 3 thickness, the thickness of connection ring 1 is greater than the thickness in channel 4, in order to improve the overall sealing performance of device, connection
Ring 1 is made of elastic material, and connection ring 1, flexible seal cover 3 and channel 4 are made into integration by elastic material.
Flexible seal cover 3 is not when by external force in the flexible convex closure 31 for protruding from 1 outer end face of connection ring or when soft
Property seal closure 3 on the inside of when being in barotropic state flexible seal cover 3 be in protrude from the flexible convex closure 31 of 1 outer end face of connection ring, channel
4 are set on flexible convex closure 31；Incision protective sleeve docking structure 2 includes the annular snap groove 10 that 1 inner wall of connection ring is arranged in, ring
The shape of shape snap groove 10 and the ring body of incision protective sleeve 11 are adapted.
Specifically, outer end face or flexible seal cover 3 of the flexible seal cover 3 in relaxed state beyond connection ring 1 exist
In planar and be parallel to the outer end face of connection ring 1 when relaxed state.In the above scheme, flexible seal cover 3 is in unaerated
It is flushed in relaxed state or with the outer end face of connection ring 1, when inflating in flexible seal cover 3, flexible seal cover 3 is just heaved
It forms flexible convex closure 31 and protrudes from the outer end face of connection ring 1, the protrusion of flexible seal cover 3, which can be improved further, to be fixed on
The flexible movement of instrument in channel 4, and in the case where being flushed relative to flexible seal cover 3 with the outer end face of connection ring 1, it is flexible
When the protrusion of seal closure 3, the rotational angle of instrument is bigger, and operating space is also bigger.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although channel 4, casing 12, disconnecting prevention structure 13, bulge loop 14, connection ring 1, incision protection is used more herein
Set docking structure 2, flexible seal cover 3, flexible convex closure 31, incision protective sleeve 11, endoscope insertion channel 41, instrument insertion are logical
The terms such as road 42, reserved channel 43, but it does not exclude the possibility of using other terms.The use of these items is only for more
The essence for easily describing and explaining the utility model, it is practical new with this for being construed as any additional limitation all
Type spirit is disagreed.
