Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and more specifically to an auxiliary device used in ultrasonic endoscopic examination. Background Art

[0002] Endoscopic ultrasound (EUS) is a gastrointestinal examination technology that combines endoscopy and ultrasound. A miniature high-frequency ultrasound probe is placed on the top of the endoscope, which is inserted into the body cavity along the patient's mouth. While the endoscope directly observes the gastrointestinal mucosal lesions, real-time scanning can be performed using endoscopic ultrasound. The histological characteristics of the hierarchical structure of the gastrointestinal tract and ultrasound images of the surrounding adjacent organs can be obtained, thereby further improving the diagnostic level of endoscopy and ultrasound. During endoscopic ultrasound examination, although the examination bed can raise the head of the bed, the patient's head still needs to be raised and positioned to a certain extent. A pillow is usually added to assist, but ordinary pillows are soft and severely deformed, and cannot adapt to the side-down positioning support of the head, making it inconvenient to fix the patient's head position during the existing test and difficult to maintain the body position during the test, causing discomfort to the patient and inconvenience in the test operation; in addition, we also found in actual clinical practice that endoscopic ultrasound examination is sometimes a sedation examination (the patient is awake but cannot move, and will not feel very uncomfortable, which is milder than anesthesia). The patient is conscious during the test and faces the operator. During the operation, the patient looks directly at the operating physician, which is prone to psychological discomfort such as fear; in addition, a large amount of water in the mouth can be sucked out through the suction device during the test, but there is still a small amount of saliva secretion overflowing from the lower corner of the mouth (commonly known as drooling), and this part cannot be sucked out by the suction device. The current practice is that the patient brings his own towel pad to absorb it underneath, which brings inconvenience to the operation. Summary of the invention
