Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a device for attracting blood clots in the stomach under gastroscopy. Background Art

[0002] In the medical field, especially in emergency gastroscopy treatment of patients with upper gastrointestinal bleeding, dealing with large amounts of blood clots in the stomach is a thorny issue. Existing treatment methods have many drawbacks.

[0003] The traditional method of simply relying on gastroscopy to attract and repeatedly pass the foreign body basket in and out of the esophagus and stomach is complicated and time-consuming, resulting in extremely low efficiency in removing blood clots. Due to the repetitiveness and complexity of the operation, the risk of mechanical stimulation and injury to the throat, esophagus, and gastric mucosa is increased. This frequent and imprecise operation can easily damage the fragile mucosal tissue, which may not only cause new bleeding points, but also aggravate the original bleeding condition, such as causing serious complications such as ruptured bleeding of esophageal and gastric varicose veins.

[0004] When passing through the throat, existing devices often cause scratches and squeezes to the throat and esophageal mucosa due to unreasonable structural design, causing discomfort and additional damage to the patient. In addition, existing suction devices lack effective positioning and guiding mechanisms when attracting blood clots, resulting in unstable suction effects and inability to quickly and accurately remove blood clots. Summary of the invention

[0005] In order to overcome the existing problems, the embodiment of the present application provides a device for suctioning blood clots in the stomach under gastroscopy, including a protective sleeve, a gastroscope body sleeved inside the protective sleeve, and a suction tube, the suction tube is connected to the negative pressure device, and the external negative pressure suction design can accurately and powerfully remove blood clots, avoiding the possibility of mucosal damage and re-bleeding caused by repeated operations in traditional methods, and can quickly and efficiently remove blood clots in the stomach, greatly improving the efficiency of blood clot removal and shortening the treatment time.

[0008] Among them, the gastroscope body is used to observe the condition of the stomach, one end of the suction tube is connected to external negative pressure suction, which is used to quickly remove blood clots in the stomach, and the protective sleeve is a soft deformable structure. When the protective sleeve is inserted into the stomach, the deformable structure of the protective sleeve enables it to pass through the throat and esophagus smoothly, reducing the irritation and damage to the mucosa. When it reaches the stomach, the doctor starts it through the external negative pressure suction device to quickly remove the blood clot through the suction tube.

[0009] Preferably, a protective cover is provided at one end of the protective cover, and the protective cover and the protective cover are detachable structures for providing protection for the gastroscope body and the suction tube inside the protective cover.
