In check valve air inlet one end, outlet one end of check valve connects air bag.The setting structure is simple, and manufacturing cost is low；And it inflates
Pipe outlet side is removably connected to check valve air inlet one end, and then after the completion of inflation, and gas tube can be removed to taking-up, avoid accounting for
With operative space, also avoids occupying fistulization oral, facilitate the progress of operation；When need to be inflated again, after being sterilized to gas tube
It is connect again with air bag, guarantee is clean, sanitary, avoids wound infection, easy to use.
Further, the outlet side of the gas tube and check valve air inlet one end are detachably connected by plug connector；It is described
Plug connector includes connector and the slotting cover with connector cooperation, and gas distribution channel is formed in the connector, and the connector and slotting cover are respectively arranged on
The outlet side of gas tube and air inlet one end of check valve.Connector and the grafting area for inserting cover are big, firm plug, stabilization.
Further, the outlet side of connector one end connection gas tube, air inlet one end of check valve, which penetrates, inserts cover bottom；
The connector other end, which protrudes into, to be inserted in cover and is socketed on outside check valve air inlet one end；The connector is successively arranged outer elasticity from outside to inside
Layer, amorphous intermediate layer and interior elastic layer.When connection, the outer wall of connector can be sealed with slotting cover inner wall, and inserting cover inner wall then can be with list
It is sealed to air inlet one end of valve, dual-seal improves anti-gas-leak effect；And the connector outer elastic layer and interior elastic layer can
It further increases connector and inserts the sealing effect of cover, check valve；Amorphous intermediate layer material is harder, facilitates grafting.
Further, the slotting cover inner wall and connector outer wall are tapered, and inserting cover has the big opening end being inserted into for connector.
The shape design can facilitate connector into and out.
Further, the slotting cover inner wall extends into elongated convex ribs along gas flow direction equipped with several.Connector insertion
After inserting in cover, convex ribs can be pressed further by connector, improve the fastness and leakproofness of plug grafting, and the elongated convex ribs can also
Effectively reduce the resistance of connector insertion.
Further, the gas tube side is equipped with lug close to joint or connector side.It can be clamped with surgical clamp
Lug, and then it is moved easily connector.
Further, the check valve periphery is equipped with chimb.Chimb and connector can be clamped by surgical clamp, then compressed,
Improve the fastness and stability of connector grafting.
In conclusion the utility model has structure simple, manufacturing cost is low, and can be removably mounted gas tube, avoids occupying
Operative space.

Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality
The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.
As shown in Figure 1-3, a kind of laparoscopic surgery eyelid retractor, including air bag 1, check valve 2 and gas tube 3, the inflation
Pipe 3 has inlet end and outlet side, and gas tube 3 can may be hard tube for hose, can design as needed.The gas tube
3 outlet side is removably connected to 2 air inlet one end of check valve, and outlet one end of check valve 2 connects air bag 1.
Above-mentioned detachable connection method can be threaded connection, clamping etc..But in the present embodiment, it tears open for convenience
Dress, then the outlet side of the gas tube 3 and 2 air inlet one end of check valve are detachably connected by plug connector 4.The plug connector 4
Including connector 41 and cover 42 is inserted, connector 41 can be with slotting 42 cooperation grafting of cover.Gas distribution channel 43, the connector are formed in the connector 41
41 are respectively arranged on the outlet side of gas tube 3 and air inlet one end of check valve 2 with cover 42 is inserted.It can be that connector 41 is set to gas tube
On 3, air inlet one end that cover 42 is set to check valve 2 is inserted, the position for inserting cover 42 and connector 41 is also interchangeable.
In the present embodiment, the outlet side of 41 one end of connector connection gas tube 3, air inlet one end of check valve 2 penetrates
Insert 42 bottoms of cover；41 other end of connector, which protrudes into, to be inserted in cover 42 and is socketed on outside air inlet one end of check valve 2.I.e. after grafting, connector
Air inlet one end outer wall of 41 inner wall fitting check valve 2, the outer wall of connector 41 fit in the inner wall for inserting cover 42.
In order to guarantee the fastness and stability of 41 grafting of connector, then the connector 41 is successively arranged outer bullet from outside to inside
Property layer 41a, amorphous intermediate layer 41b and interior elastic layer 41c.The outer elastic layer 41a and interior elastic layer 41c are by elastic material system
At.The amorphous intermediate layer 41b is then made of hard materials such as plastics.
And in order to further facilitate the dismounting of connector 41, then, 42 inner walls of the slotting cover and 41 outer wall of connector are at cone
Shape, inserting cover 42 has the big opening end being inserted into for connector 41.It inserts 42 lesser one end of opening of cover and connects check valve 2, insert cover 42
Biggish one end be open for the insertion of connector 41.After grafting, 42 inner walls of cover are inserted with 41 outer wall of connector and are bonded setting.In order to further mention
Stability after high 41 grafting of connector, 42 inner walls of the slotting cover are equipped with several convex ribs 42a, and convex ribs 42a is along gas flow direction
It extends into elongated.After 42 grafting of connector 41 and slotting cover, convex ribs 42a can extrude 41 outer wall of connector, further increase the installation of connector 41
Fastness.
In addition, shift joint 41 for convenience, then, 3 side of gas tube are equipped with lug 5 at connector 41, it can
With surgical clamp retaining lug 5, plug or shift joint 41 facilitate the dismounting of connector 41.Certainly, the lug 5 can also be set to
41 lateral position of connector, and the shape of lug 5 can be set as needed, is preferably devised to flat-shaped, facilitates clamping.
