Specific embodiment
As shown in figs 1 to 6, the endoscope-assistant surgery single-hole multi-channel road in this programme enters system, including incision protective sleeve a and
Endoscope-assistant surgery single-hole multi-channel road enters device b, and it includes connection ring 1, incision protective sleeve that endoscope-assistant surgery single-hole multi-channel road, which enters device b,
A includes outer ring body 2, and docking structure 3 is equipped between one end and outer ring body 2 of connection ring 1, is equipped in the other end of connection ring 1 soft
Property seal closure 4, flexible seal cover 4 is not when by external force in the flexible convex closure 5 for protruding from 1 outer end face of connection ring or when soft
Property seal closure 4 on the inside of when being in barotropic state flexible seal cover 4 be in protrude from the flexible convex closure 5 of 1 outer end face of connection ring, flexible convex
If packet 5 is equipped with dry passage 6, connection ring 1 or flexible seal cover 4 are equipped with air intake structure and air outlet structure.Flexible seal cover 4 wraps
Cylindrical portion 51 is included, one end of cylindrical portion 51 is open end, and the other end is closed end 52, one end phase of open end and connection ring 1
Even, channel 6 is arranged on the closed end 52 of cylindrical portion 51 or the side of cylindrical portion 51, and closed end 52 is arc-shaped to arch upward.
This programme by the way that the channel that passes through for instrument is arranged on flexible seal cover, enable instrument with channel together
Flexible rotating, and the angle rotated is larger, carries out convenient for the operation of operation.
Specifically, flexible seal cover 4 is not when by external force without departing from the outer end face of connection ring 1；Alternatively, flexible
The outer end face beyond connection ring 1 when not by external force of seal closure 4；Flexible seal cover 4 is in planar and is parallel to connection ring
1 outer end face, and when being on the inside of flexible seal cover 4 barotropic state flexible seal cover 4 in protruding from 1 outer end face of connection ring
Flexible convex closure 5.
Above-mentioned flexible seal cover 4 is outer without departing from connection ring 1 when not by external force in one of the embodiments,
The scope of activities of end face, the surgical instrument in the embodiment is smaller.
In another embodiment, flexible seal cover 4 is in outer end face that is planar and being parallel to connection ring 1, and when flexible close
Flexible seal cover 4 is in the flexible convex closure 4 for protruding from 1 outer end face of connection ring when being in barotropic state on the inside of sealing cover 4.In above-mentioned side
In case, flexible seal cover 4 is flushed in unaerated in relaxed state or with the outer end face of connection ring 1, when flexible seal cover 4
When interior inflation, the outer end face of connection ring 1 is just heaved and protruded to flexible seal cover 4, and the protrusion of flexible seal cover 4 can be further
Raising be fixed on the flexible movement of the instrument in channel 5, and flushed relative to flexible seal cover 4 with the outer end face of connection ring 1
In the case where, when the protrusion of flexible seal cover 4, the rotational angle of instrument is bigger, and operating space is also bigger.
In another embodiment, the outer end face beyond connection ring 1 when not by external force of flexible seal cover 4.This programme
In flexible seal cover 4 state raised to the outer end face of connection ring 1 is at when non-aerating, flexibility can be ensured after inflation
Seal closure 4 is more stood upright, its run-off the straight under own wt is better protected from.
In order to improve the air-tightness of system entirety, connection ring 1 and flexible seal cover 4 be made into integration or connection ring 1 with
4 circumferential seal of flexible seal cover is connected；Flexible seal cover 4 and channel 6 are made into integration or 6 circumferential direction of flexible seal cover 4 and channel
Sealing is connected；Air pipe sleeve 7 and flexible seal cover 4 are made into integration or connection ring 1 is connected with 4 circumferential seal of flexible seal cover.
Similarly, connection ring 1, flexible seal cover 4, channel 6 and air pipe sleeve 7 are made of elastic material, the thickness of connection ring 1
Degree is respectively greater than the thickness of flexible seal cover 4, channel 6 and air pipe sleeve 7, and connection ring 1, flexible seal cover 4, channel 6 and tracheae
Set 7 is an integral structure by mold integrated molding.
