Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a hemostatic balloon for an endoscope and a digestive tract hemostasis device. Background Art

[0002] An endoscope is a tubular interventional operating instrument equipped with a visual light source. The endoscope can enter the human body through the natural body cavities (nasal cavity, airway, esophagus-stomach, intestine, urinary tract, etc.) of the human body, or through a small surgical incision.

[0003] For bleeding in the bulb and duodenum of the digestive tract, the current endoscope uses an electric knife for hemostasis. However, due to the relatively weak part of the digestive tract, the use of an electric knife for hemostasis is likely to cause perforation of the digestive tract wall.

[0004] After retrieval, the utility model patent with the patent number CN212879240U discloses a multifunctional endoscope balloon module. By detachably sleeving the balloon module on the front end of the endoscope, it is possible to compress and stop bleeding at the bleeding point. However, when the above patent is used, the endoscope and the balloon module will block the digestive tract, resulting in the inability of the food in the stomach and intestines to pass through the digestive tract, causing food accumulation in the stomach. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a hemostatic balloon for an endoscope and a digestive tract hemostasis device, which can bring the balloon into the digestive tract through the endoscope to compress the bleeding point, and leave a passage for food to pass through. The food in the stomach and intestines can pass through this passage, which helps to reduce the occurrence of food accumulation in the stomach and reduce the occurrence of flatulence.

[0006] In a first aspect, the utility model provides a hemostatic balloon for an endoscope, comprising:

[0007] A first balloon, provided with a clamping channel penetrating through opposite ends, and the clamping channel is arranged on the central axis of the first balloon;

[0008] A second balloon, arranged on a side of the first balloon facing away from the clamping channel;

[0009] A first trachea, connected to the first balloon;

[0010] A second trachea, connected to the second balloon;

[0011] Wherein, the first trachea can deliver or extract gas to the first balloon, so that the clamping channel of the first balloon is reduced or enlarged, thereby fixing or detaching the first balloon from the front end of the endoscope; the second trachea can deliver gas to the second balloon, so that the second balloon expands to compress the bleeding point.

[0012] For the hemostatic balloon for endoscope provided by the present utility model, when the first balloon expands under the control of the first air tube, the clamping channel can be narrowed, so that the first balloon can be clamped and fixed on the front end of the endoscope; when the front end of the endoscope moves to the gastrointestinal bleeding point of the patient, when the first balloon shrinks under the control of the first air tube, the clamping channel can be enlarged, so that the front end of the endoscope can be withdrawn from the clamping channel; finally, when the second balloon expands under the control of the second air tube, the compression hemostasis of the bleeding point can be completed. At this time, food can pass through the digestive tract through the clamping channel, which helps to reduce the accumulation of food in the stomach and reduce the occurrence of gastric distension.

[0013] Further, when the first balloon is filled with gas, its shape is cylindrical.

[0014] Further, when the second balloon is filled with gas, its shape is cylindrical or wedge-shaped.

[0015] Further, a rubber ring is provided on one side of the first balloon facing the clamping channel, and the rubber ring can shrink as the first balloon shrinks.

[0016] Adopting the above technical solution, setting the rubber ring helps to increase the friction coefficient on the side of the first balloon facing the clamping channel and improve the connection stability between the first balloon and the endoscope after inflation.

[0017] Further, the number of the rubber rings is multiple, and the multiple rubber rings are arranged at intervals along the axial direction of the first balloon.

[0018] Adopting the above technical solution, increasing the number of rubber rings helps to further improve the connection stability between the first balloon and the endoscope after inflation.

[0019] Further, a rubber block is provided on one side of the first balloon facing the clamping channel.

[0020] Adopting the above technical solution, setting the rubber block helps to increase the friction coefficient on the side of the first balloon facing the clamping channel and improve the connection stability between the first balloon and the endoscope after inflation.

[0021] Further, the number of the rubber blocks is multiple, and the multiple rubber blocks are arranged at intervals along the axial direction of the first balloon; and / or, the number of the rubber blocks is multiple, and the multiple rubber blocks are arranged at intervals along the circumferential direction of the clamping channel.

[0022] Adopting the above technical solution, increasing the number of rubber blocks helps to further improve the connection stability between the first balloon and the endoscope after inflation.

[0023] In a second aspect, a digestive tract hemostasis device provided by the present utility model includes:

[0024] The hemostatic balloon for endoscope as described in any one of the above;

[0025] An endoscope, with the first balloon disposed at the front end of the endoscope.

[0026] Further, an annular slot is provided on the endoscope, and the inflated first balloon can be clamped and fixed by the annular slot.

[0027] With the above technical solution, by providing an annular slot at the front end of the endoscope, the first balloon can be engaged in the annular slot after inflation, thereby reducing the occurrence of accidental misalignment when the first balloon moves while attached to the endoscope, facilitating medical staff to control the second balloon to accurately compress the bleeding point.

[0028] Further, the perimeter of the front slot wall of the annular slot is arranged to decrease from the front end to the rear end.

[0029] With the above technical solution, the perimeter of the front slot wall of the annular slot is arranged to decrease from the front end to the rear end. When the first balloon is separated from the endoscope, the perimeter of the front slot wall of the annular slot can guide the first balloon to detach from the endoscope, helping to reduce the occurrence of misalignment of the endoscope driving the first balloon.

[0030] As can be seen from the above, for the hemostatic balloon for endoscope provided by the present utility model, the first balloon is controlled by the first air tube to expand, which can cause the clamping channel to shrink, so that the first balloon can be clamped and fixed on the front end of the endoscope; when the front end of the endoscope moves to the digestive tract bleeding point of the patient, the first balloon is controlled by the first air tube to shrink, which can cause the clamping channel to expand, so that the front end of the endoscope can be withdrawn from the clamping channel; finally, the second balloon is controlled by the second air tube to expand, and the compression hemostasis of the bleeding point can be completed. At this time, food can pass through the digestive tract through the clamping channel, helping to reduce the accumulation of food in the stomach and the occurrence of gastric distension.
