Abstract
Description
Technical Field
[0001] The utility model relates to the field of ultrasonic endoscopes, in particular to an ultrasonic endoscope auxiliary device. Background Art
[0002] Circular scanning ultrasound endoscopy uses a conventional endoscope as a carrier, and uses the ultrasonic transmitting and receiving device at the front end of the endoscope to detect lesions in the digestive tract wall and tissues and organs outside the wall. Not only can it get as close as possible to the suspected lesion in the body, but it can also use ultrasound to determine the nature, size and depth of the lesion, which is particularly suitable for the diagnosis of malignant tumors and their invasion depth. At the same time, the circular scanning ultrasound endoscopy can also clearly display the organs and lymph nodes within 10 cm around the lesion.
[0003] During the circumferential scanning ultrasound endoscopic examination, water needs to be injected into the patient's digestive cavity (esophagus, stomach, duodenum, colon) through the water injection channel of the endoscope. Using water as a medium can enable the ultrasound endoscope to observe the lesions more clearly. Figure 1 As shown, it includes an endoscope body 1, a probe 11 is fixedly provided at the inner end of the endoscope body 1, and a water injection pipe 2 is provided on one side of the endoscope body 1, and the water injection pipe 2 is fixedly connected to the endoscope body 1 through a fixing ring 12. During the examination, the patient usually takes the left side lying position. Under the gravity of the body position, the patient's digestive cavity cannot store water well at the lesion position. At this time, the clinician needs to repeatedly pump water to observe the lesion, which not only increases the workload of the doctor, but also causes gastrointestinal discomfort, abdominal distension, etc. in the patient, and may also increase the risk of aspiration in the patient. The Chinese utility model patent with application number 01217098.4 discloses a water blocking device for ultrasonic endoscope. It includes a hose, a catheter in the hose, and an air bag at the front end of the catheter, and the inner cavity of the air bag is connected to the inner cavity of the catheter.
[0004] The ultrasonic endoscope water blocking device with the above structure is suitable for water blocking during ultrasonic endoscope examination. It can obtain satisfactory ultrasonic images and make accurate diagnoses. However, it can only block water at the front end through the airbag, and cannot form a closed space to drain the injected water, which will still cause discomfort to the patient due to water injection; and the airbag fits the intestinal wall when inflated, and the pipe needs to be rotated during ultrasonic examination, which will cause friction between the airbag and the intestinal wall, causing pain to the patient or damage to the intestinal wall.
