Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary devices, more particularly, to a visual guiding and supporting gastric tube device. BACKGROUND

[0002] A gastric tube is a medical auxiliary device inserted through the oral cavity, pharynx and esophagus to the stomach, which can mainly function as gastrointestinal decompression and nasogastric feeding. The gastric tube plays an important role in many different types of surgery.

[0003] Among them, the gastric tube has been widely used in weight loss surgery. However, during the weight loss surgery, the patient is in a tracheal intubation state under general anesthesia, and when the gastric tube is inserted through the mouth, the oral pharynx is often narrow due to the patient's tongue falling backward or obesity, which makes the gastric tube intubation operation not smooth, causing damage to the oral pharynx. In order to insert the gastric tube into the esophagus and stomach, the tongue root needs to be lifted manually to open the oral pharynx and the mandible needs to be raised. In most gastric tube intubations, there is resistance when the gastric tube enters the cardia, which requires adjusting the angle of the gastric tube or the assistance of the surgeon under laparoscopic visualization to complete the insertion of the gastric tube, resulting in increased difficulty in operation. Moreover, excessive force during adjustment can easily damage the esophagus, gastric mucosa and other tissues, which has an adverse effect on the patient's postoperative recovery.

[0004] The existing gastric tube still has many shortcomings in actual application, including that the existing gastric tube does not have a visual function, there is a certain visual blind area during intubation, precise positioning cannot be achieved during surgery, which increases the difficulty of intubation and easily damages the digestive tract; the existing gastric tube does not have a splash-proof function, and during the operation process, the gastric contents can easily splash or flow out, causing pollution to the external environment and greatly increasing the risk of infection control; the existing gastric tube does not have a protection structure, and the gastric contents and oral secretions carried out with the gastric tube during the adjustment of the gastric tube position during the operation pollute the surrounding environment and the anesthesia pipeline; the existing gastric tube does not have a cleaning cavity function, and the body cavity of the gastric tube main tube is large, which can easily reflux when using methylene blue marking liquid to measure leakage at the cutting anastomosis site during the operation.
