Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1-4, the present embodiment provides a hemostatic method for esophageal varices, which is a hemostatic device for bleeding from an injection hole of a vein during varices.

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 limiting structure 2 is embedded in the hemostatic sleeve 1 and is provided with a limiting wire for limiting the advance of the gastroscope, so that the end surface of the front end of the probe is staggered with the end surface of the hemostatic sleeve 1. In the present embodiment, the position limiting structure 2 is a position limiting ring. The inner ring of the limit ring protrudes out of the inner wall of the hemostatic sleeve 1, and the outer ring of the limit ring protrudes out of the outer wall of the hemostatic sleeve 1. In other embodiments, the position limiting structure 2 may be other structures capable of limiting the gastroscope, which can prevent the front end of the probe from directly passing through the hemostatic sleeve 1, so that a section is reserved in front of the hemostatic sleeve 1 as a part for pressing hemostasis.

In the present embodiment, the connection structure 3 includes a connection pipe and a reinforcing mesh (not shown in the drawings). The connecting pipe is sleeved on the gastroscope, and the two ends of the connecting pipe are respectively connected with the hemostatic sleeve 1 and the varicose vein gasbag 4. 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.
On the basis of this hemostatic device, the hemostatic method in the present embodiment includes the following steps.
(1) And sleeving the hemostasis device on the front end of the gastroscope. The step is a sleeving step, and the assembling work of the hemostasis device and the gastroscope is realized.
(2) The gastroscope and hemostatic device are placed into the esophagus. The step is an embedding step, namely, the related device is embedded into the esophagus of a human body, and the embedding step can be realized through a machine or can be manually operated.
(3) The varicose vein balloon 4 is opened and the varicose vein balloon 4 is inflated to block the connection between the vein and the atrium to prevent the sclerosant agent in the varicose vein operation from flowing in the direction of the atrium. This step is an inflation step of inflating the varicose vein balloon 4 to sufficiently inflate the varicose vein balloon 4 to perform occlusion.
(4) Injecting a foam hardener into the injection hole, and recovering the corresponding needle tube after the injection is completed. The step is an injection step, namely the injection work of the foam hardener is realized.
(5) The control gastroscope drives hemostasis cover 1 motion, sees through transparent structure and observes and confirm corresponding bleeding point through light among the gastroscope to press hemostasis to the bleeding point through the outside of hemostasis cover 1. The step is the main step of hemostasis, and accurate hemostasis is carried out on bleeding points through the hemostasis sleeve 1, so that the condition that excessive bleeding shields the visual field of a gastroscope and other adverse effects are prevented.
