Detailed description of the invention
Fig. 1 is the sealing valve mechanism decomposition diagram that the utility model is used for instrument channel；
Fig. 2 is the sealing valve mechanism schematic diagram that instrument channel is used for described in the utility model embodiment one；
Fig. 3 is the sealing valve mechanism schematic diagram that instrument channel is used for described in the utility model embodiment two.
In figure:
1, connector portions 1-1, instrument port 1-2, seal chamber
1-3, shell 2, seal sleeve 3, locking sleeve
4, sleeve 5, the first gasket 6, the second gasket are connected
7, guide part 8, instrument channel 9, auxiliary plug-in
Specific embodiment
It elaborates with reference to the accompanying drawing to specific embodiment of the utility model.
As shown in Figure 1, the utility model include connector portions 1, seal sleeve 2, locking sleeve 3, connection sleeve 4, first it is close
Packing 5, the second gasket 6 and guide part 7；Wherein connector portions 1 include instrument port 1-1, seal chamber 1-2 and shell 1-3；It is described
Seal sleeve 2 is located in the seal chamber 1-2, and described 3 one end of locking sleeve is threadedly coupled with the shell 1-3；The other end with
The connection sleeve 4 is threadedly coupled；First gasket 5 is placed in the step for connecting sleeve 4 with 6 intussusception of the second gasket；It leads
It is connected to portion 7 with the step for connecting sleeve 4.
The seal sleeve 2 includes silica shell and instrument through-hole.The guide part 7 includes importing port and clamping ring, institute
It states clamping ring and is connected with the step for connecting sleeve 4.First gasket, 5 arc end is provided with gap, in second gasket 6
It is provided with instrument circular hole.The seal sleeve 2, the first gasket 5 and the second gasket 6 are silica gel material.
Embodiment one: it is used in the case of no auxiliary plug-in:
As shown in figure 3, the instrument port 1-1 of connector portions 1 is connected with the instrument channel 8 of endoscope.Surgical instrument is by leading
It is inserted into portion 7, the importing port of guide part facilitates the insertion of surgical instrument, and surgical instrument passes sequentially through the second gasket 6 and the
One gasket 5, the instrument circular hole of the second gasket 6 stress when surgical instrument is inserted into become larger, since the elasticity of silica gel material is made
With surgical instrument capable of tightly being touched, to play the role of preventing internal water from flowing out.The effect of first gasket 5 is to prevent not
It plugs in instrument state and is lauched spilling, it is under natural conditions sealing state that arc end, which is equipped with gap,.Then surgical instrument passes through connection
