Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1:
The anti-reflux plugging device of a kind of natural cavity endoscopic surgery through stomach, esophagus approach according to Fig. 1, Fig. 2, comprises outer tube 2, inflation push-and-pull assembly 5, gas tube 4, connecting line 3, plugging device 1, handle 6 and draught line 7. Inflation push-and-pull assembly 5 is made up of release cover 51 and release bracelet 52, and release and overlap 51 tail ends that are connected to gas tube 4, described tail end represents one end of air inlet. Gas tube 4 is placed in the inside of outer tube 2, releases bracelet 52 and is connected on release cover 51, pull and release bracelet 52, gas tube 4 relative outer tube 2 axially-movable can be made. Described plugging device 1 is inner is shutoff core 11, and shutoff core 11 main body is cylinder, the outside shutoff outer tube 15 that surrounds, logical passage 14 during shutoff core 11 has. Shutoff core 11 one end is concordant with shutoff outer tube 15 air inlet pipe one end, chamber is formed between the other end and shutoff outer tube 15, in chamber by air bag 12 be connected on passage 14 end face, the partition 13 of one-way ventilating is had between passage 14 and air bag 12, one-way ventilating is generally that passage 14 arrival end can to port of export air inlet, otherwise then can not. The port of export of blow vent 14 is connected with air bag 12, and the air bag 12 after air inlet can constantly be heaved. Described gas tube 4 can insert in an initial condition in passage 14, in intake process, keeps gas tube 4 corresponding with passage 14 position always. Plugging device 1 is fixed with connecting line 3, the casing wall of the port of export of outer tube 2 has through hole, connecting line 3 to outer tube 2 inside, forms cover through through hole in inside, socket gas tube 4. When gas tube 4 inserts passage 14 inside, plugging device 1 also can be relative fixing with outer tube 2 position, and when gas tube 4 is drawn back to the through hole back-end of outer tube 2, depart from cover, then plugging device 1 also can be separated with outer tube 2. The rear end surface of outer tube 2 there is handle 6, pull handle, outer tube 2 can be made to extract out. Plugging device 1 is fixedly connected with draught line 7.
Embodiment 2:
A kind of anti-reflux plugging device of the natural cavity endoscopic surgery through stomach, esophagus approach, plugging device 1 is connected with outer tube 2 is closed, described closure connection refers to compact siro spinning technology between plugging device 1 and outer tube 2, and gas tube 4 end of outer tube 2 inside inserts passage 14 inside of plugging device 1. Promote bracelet 52 plugging device 1 is placed in duodenal bulb, pump-up device is carried out to gas injection by gas tube 4 to inside, gas is by gas ducting and passage 14, because the reason of one-way ventilating partition 13, make can only constantly heave in air bag 12 gas injection process, air bag 12 after heaving is fixed on bulb, and plugging device 1 just can be fixed on duodenal bulb like this. Pull back inflation push-and-pull assembly 5, gas tube 4 is axially return backward, when returning to outer tube 2 inside, depart from the line cover of connecting line 3, connecting line 3 detaches along outer tube 2 through hole, makes outer tube 2 lose with before plugging device 1 restriction being connected, outer tube can be extracted out smoothly and perform the operation. After operation terminates, can air bag 12 be poked with Special surgical utensil and clamp connecting line 3 with biopsy forceps, plugging device is taken out from internal diameter biopsy duct or by draught line 7, plugging device 1 taken out.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
