Wherein, the device comprises a hemostatic sleeve 1, a limiting structure 2, a connecting structure 3 and a varicose vein gasbag 4.
The hemostatic sleeve 1 is sleeved on the front end of a probe of a gastroscope in varicose vein operation. The hemostatic sleeve 1 is a transparent structure made of polymer materials, and the inner diameter of the hemostatic sleeve 1 is smaller than the diameter of the probe so as to generate relative friction force between the front end of the probe and the hemostatic sleeve 1. In this embodiment, the hemostatic sleeve 1 includes a pressing section 11 and a sleeving section 12. The pressing section 11 and the sleeving section 12 are coaxially arranged and are connected through the limiting structure 2. The pressing section 11 is used for pressing a bleeding point, and the sleeving section 12 is sleeved on the front end of the probe. At least one through hole 13 is arranged on the side wall of the hemostatic sleeve 1, and the through hole 13 is arranged between the pressing section 11 and the sleeving section 12. When pressing, because the gastroscope front end can not be arranged in pressing section 11, press section 11 like this and can be softer to the effect of pressing of bleeding point, can prevent that the gastroscope front end direct application of force from causing from pressing excessively to the reduction is to the injury by the operator, promotes hemostasis quality.
The hemostatic sleeve 1 functions to press hemostasis, and the outer side surface thereof is used to fit a bleeding point at the injection hole, which is similar to pressing a blood-pressing position with a finger. Because hemostasis cover 1 is made for polymerization macromolecular material, it is transparent structure, operating personnel just can directly see through hemostasis cover 1 and observe the image around hemostasis cover 1 through the gastroscope like this, and then press bleeding point through removing hemostasis cover 1, prevent the blood outflow, promote the operation experience, avoid these blood outflow and other a series of adverse effects that produce. In addition, because the internal diameter of the hemostatic sleeve 1 is smaller than the diameter of the probe, the hemostatic sleeve 1 and the probe can be tightly connected, and further a certain relative friction force can be generated, so that the hemostatic sleeve 1 is more stable after being installed, and can be easily removed when being removed, and the hemostatic sleeve is convenient to use.

The reinforcing net is laid in the pipe wall of the connecting pipe. Wherein, the reinforcing net is a nylon net and is evenly wrapped on the outer wall of the connecting pipe. Because the reinforcing net adopts the nylon net, the nylon net is similar to a nylon device, has strong flexibility and has the effects of abrasion resistance and tear resistance. When the gastroscope is at rotatory in-process, connection structure 3 can guarantee the fastness of being connected between hemostatic cover 1 and varicose gasbag 4, is convenient for gastroscope angle of adjustment in order to observe.
The varicosity air bag 4 is fixedly connected with the other end of the connecting structure 3, is sleeved on the gastroscope, and is used for blocking the connection between the vein and the atrium after being opened and inflated, so that a hardening agent in the varicosity surgery is prevented from flowing towards the atrium direction. In this embodiment, the varicose vein balloon 4 includes a balloon structure 41 and a trachea 42. The air bag structure 41 is fitted over the other end of the connecting structure 3, and the air tube 42 is used to inflate the air bag structure 41 or to discharge the air in the air bag structure 41. Wherein, the air bag structure 41 is in a flat sphere shape, and the polar radius direction is parallel to the axial direction of the hemostatic sleeve 1.
Wherein, in the varicose vein operation, after the foam sclerosing agent enters from the injection hole, the operator can observe and determine the corresponding bleeding point through the light ray in the gastroscope passing through the transparent structure, and press the bleeding point through the outer side surface of the hemostatic sleeve 1 to stop bleeding. Actually, in varicose vein operation, can suit the whole device in the gastroscope front end earlier, then along with the gastroscope gets into the esophagus, then varicose vein gasbag 4 opens and blocks the connection of vein and atrium, later injects the foam sclerosing agent through the handle hole, and the needle tubing of injection foam sclerosing agent is withdrawed, then controls the gastroscope and drives hemostasis cover 1 forward, utilizes hemostasis cover 1 to compress the hole that bleeds and stanch.
In summary, compared with the existing varicose vein operation device, the device for treating esophageal varicose vein bleeding of the embodiment has the following advantages:
1. this treatment esophageal varices device that operation is bled, it is connected between vein and the atrium through varices gasbag 4 after aerifing, sclerosing agent in the prevention varices operation flows towards the atrium direction and blocks, after the foam sclerosing agent gets into from the injection orifice, operating personnel can see through transparent structure and observe and confirm corresponding bleeding point through the ray in the gastroscope, and press the hemostasis to the bleeding point through the outside of hemostasis cover 1, just so can reduce blood and flow out from the injection orifice, can avoid these blood that flow out to cause the influence to the gastroscope field of vision on the one hand, be convenient for observe the operation position, guarantee the success rate of operation, on the other hand is hemostatic will improve the sclerosis speed of foam sclerosing agent, improve operation efficiency. In varicose vein surgery, the varicose vein balloon 4 prevents the sclerosant from flowing to the atrium direction in the operation using the foam sclerosant, so that the sclerosant is more effective.
2. This treatment esophageal varices device that operation was bled, it presses the hemorrhage point of injection hole department through the side of hemostasis cover 1, can prevent the blood outflow like this, promotes operation experience, avoids these blood to flow out and other a series of adverse effects that produce.
3. According to the device for treating esophageal varices surgical bleeding, the hemostatic sleeve 1 is made of the polymeric polymer material, and a certain relative friction force can be formed between the hemostatic sleeve 1 and the probe, so that the hemostatic sleeve 1 is more stable after being installed, and can be easily detached when being detached, and the device is convenient to use.
4. This treatment esophageal varices surgical hemorrhage's device, its hemostasis cover 1 includes presses section 11 and cup joints section 12, presses section 11 to be used for pressing the hemorrhage point, and cup joints section 12 then is used for cup jointing with the gastroscope to the centre separates with limit structure 2, and the gastroscope just can not reach in pressing section 11 like this. When pressing, because the gastroscope front end can not be arranged in pressing section 11, press section 11 like this and can be softer to the effect of pressing of bleeding point, can prevent that the gastroscope front end direct application of force from causing from pressing excessively to the reduction is to the injury by the operator, promotes hemostasis quality.
5. The device for treating esophageal varices surgical bleeding comprises a connecting pipe and a reinforcing net, wherein the connecting pipe is reinforced through the reinforcing net. And the reinforcing net adopts a nylon net, which is similar to a nylon device, has strong flexibility and has the effects of abrasion resistance and tear resistance.
