Concrete meaning in the present invention.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in figs. 1-12, a kind of Duckbill type check valve, including the wedge angle that circular hole diaphragm seal 1 and flat are excessive to cylinder
Type structure 3, sharp 3 inner hollow of corner-shape structure, one end of sharp corner-shape structure 3 are in duck-bill type structure 31, the point of duck-bill type structure 31
Towards instrument channel, the other end of sharp corner-shape structure 3 is cylindrical plug division 32 at end, plug division 32 and circular hole diaphragm seal 1 it
Between pluggable connection, an openable and closable interpolation slit 4, the center of circular hole diaphragm seal 1 are equipped at the tip of 31 flat of duck-bill type structure
Place is equipped with a through-hole 5, and instrument sequentially passes through through-hole 5 and interpolation slit 4 from outside to inside.Circular hole diaphragm seal 1 and sharp corner-shape structure 3 are bullet
Elastomer material is made.
There are two types of structures for this case:
One kind is Contiuum type of structure: as shown in figs 1-9, i.e., passing through connection sheet between circular hole diaphragm seal 1 and sharp corner-shape structure 3
2 connections, will not be completely separable when circular hole diaphragm seal 1 and the sharp opening of corner-shape structure 3.
Another kind is split type structure: as shown in figs. 10-12, i.e., circular hole diaphragm seal 1 and sharp corner-shape structure 3 are seperated two
A independent accessory, can be completely separable when circular hole diaphragm seal 1 and the sharp opening of corner-shape structure 3.
Circular hole diaphragm seal 1 has recessed portion, fastens to the plug division 32 of sharp corner-shape structure 3.Be also possible to: plug division is recess
Place, circular hole diaphragm seal 1 are inserted into recess.
A kind of detachable check valve quick coupling is also protected in this case, unidirectional including above-mentioned Duckbill type as shown in Figure 13-19
Valve further includes valve seat 7 and lock-on connection 8, and the valve seat 7 is connected to the end of instrument channel, and check valve is removably insertable to arrive valve
In stepped hole in seat 7, on valve seat 7, check valve is wrapped in valve seat 7 by screw-threaded coupling for one end of lock-on connection 8, is locked
The other end of tight coupling 8 is equipped with instrument import 9, and instrument import 9 is horn mouth.In the one end being connect with instrument channel on valve seat 7
For tubular structure 6, grafting directly can be carried out with instrument channel.It is equipped between stepped hole and tubular structure 6 with guiding role
Excessive cone mouth, convenient for inserting instruments into instrument channel.
When surgical instrument is inserted by the instrument import 9 of the detachable check valve quick coupling of this case, instrument can be through circular hole
The interpolation slit 4 of the through-hole 5 of diaphragm seal 1 and sharp corner-shape structure 3 is inserted into instrument channel, and the interpolation slit 4 of check valve can be with when insertion
The insertion of instrument and open, at this moment have a small amount of liquid flows out in the gap between check valve and instrument, flow to circular hole sealing
At piece 1, since the outer diameter of instrument is suitable with the aperture of through-hole 5, circular hole diaphragm seal 1 can tightly wrap instrument, form sealing, prevent
Sealing stream flows outwardly.When surgical instrument exits, interpolation slit can be automatically closed.Keep surgical procedure simpler.Due to instrument
Import has bell-mouthed guide frame, quickly to position when instrument insertion.
The structure of this product can be connected directly in the instrument channel of product.It can also be the company as instrument channel
Connect device come using.The one end in channel is configured to Luer lock can be directly connected to common public female Luer, as shown in figure 20.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
