Abstract
Description
Technical Field
[0001] The present invention relates to the technical field related to medical devices, and in particular to a human body posture adjustment device and a control system for gastrointestinal endoscopy. Background Art
[0002] Gastroenteroscopy is a medical examination method that combines the examination methods of gastroscopy and colonoscopy to evaluate the health of the upper and lower digestive tracts. This examination method uses an endoscope to observe the internal conditions of the digestive tract. During the examination, the doctor will insert the gastroscope through the patient's mouth into the esophagus, and then into the stomach and duodenum in turn. The lens on the gastroscope can clearly show the fine structure of the digestive tract mucosa, helping doctors to detect inflammation, ulcers, tumors, polyps and other lesions; Colonoscopy is a special examination for observing the lower digestive tract. Before the examination, the patient needs to prepare the intestine to empty the stool and gas in the intestine. Then, the doctor will insert the colonoscope through the patient's anus into the rectum and gradually advance it into the deep part of the colon. The lens on the colonoscope can also clearly show the condition of the intestinal mucosa, helping doctors to find lesions in the intestine. At present, there are the following problems in gastrointestinal endoscopic examination: 1. At present, when patients undergo gastroscopy, they need to raise their heads to facilitate gastroscopy. However, different patients have different body shapes. When the existing examination pillows raise the head, it is not convenient to adjust the patient's head according to the patient's body shape, which affects the patient's comfort and is not convenient for gastroscopy. 2. When performing a colonoscopy, different body positions such as knee-chest position, lithotomy position, and side-lying position will be adopted according to actual needs. It is difficult for the patient to maintain the above position by himself during the examination. Over time, the patient's position is prone to change, which affects the colonoscopy.
