Vision field definition enhancement method for gastrointestinal endoscope diagnosis and treatment

Abstract

The invention discloses a visual field enhancement system (ESCGV) for gastrointestinal endoscope diagnosis and treatment. A liquid delivery tube (2) is led out from a washing bottle (1), and the liquid delivery tube (2) bypasses a first peristaltic pump ( 3). The washing bottle (1) is also equipped with a stirring and heating subsystem capable of stirring and heating the washing liquid inside. The invention also discloses a method for enhancing the clarity of the visual field of gastroenteroscopy diagnosis and treatment, which comprises 1) adding a washing liquid into the washing bottle; 2) magnetically stirring the washing liquid in the washing bottle; meanwhile, heating the washing liquid; 3) The temperature of the rinsing liquid is 25-37°C; 4) The steps of sending the rinsing liquid into the observation window of the gastroenteroscope. The invention can significantly enhance the clarity of the visual field under the gastroenteroscope, is simple and convenient to operate, can greatly reduce missed diagnosis and misdiagnosis, and can significantly improve the treatment quality of the gastroenteroscope.

Description

technical field [0001] The invention belongs to the field of medical and health technologies, and in particular relates to a system and method for enhancing visual field clarity for gastrointestinal endoscope diagnosis and treatment. Background technique [0002] At present, in the field of medical and health care, there are many gastrointestinal endoscopy diagnosis and treatment equipment. When doctors use these gastrointestinal endoscopy diagnosis and treatment equipment, because of the different conditions of patients, some patients have a lot of gastrointestinal tract foam or mucus or blood or excretion, which will cause stomach ulcers. The field of view of the colonoscopy is not clear, which affects the observation of the field of view of the gastroenteroscope, which increases the difficulty of the doctor's diagnosis and treatment, is not conducive to the timely and effective detection of the disease and accurate treatment, and the need for repeated observation increases...

[0002] At present, in the field of medical and health care, there are many gastrointestinal endoscopy diagnosis and treatment equipment. When doctors use these gastrointestinal endoscopy diagnosis and treatment equipment, because of the different conditions of patients, some patients have a lot of gastrointestinal tract foam or mucus or blood or excretion, which will cause stomach ulcers. The field of view of the colonoscopy is not clear, which affects the observation of the field of view of the gastroenteroscope, which increases the difficulty of the doctor's diagnosis and treatment, is not conducive to the timely and effective detection of the disease and accurate treatment, and the need for repeated observation increases the pain of the patient and the burden of the doctor. labor intensity

[0003] In the diagnosis and treatment of gastroenteroscopy, a flushing device is often used. This flushing device can supply physiological saline according to the actual clinical needs, and flush the part of the gastrointestinal tract through the supplied normal saline, in order to increase the clarity of the field of view of the gastroenteroscope. , but often poorly

The above-mentioned water delivery device needs to be manually operated by a special person when in use, and the flow rate and flushing time are not easy to control. If the flow rate and flushing time are too large and too long, too much liquid will be accumulated in the patient's body, which will make the patient feel sick and vomit. Reflux may also enter the trachea, increasing the risk to the patient

[0004] Chinese patent CN201020567721.8 disclosed a closed water flusher on May 4, 2011, which includes a sterilized disposable ear flushing ball and a water injection pipe with a regulating valve, and the water injection pipe communicates with the disposable ear flushing ball , the closed water flusher has a high degree of sterility, and the ear ball and water injection pipe form a closed system. During the operation, the normal saline enters the operation field through the closed system and is not exposed to the air, which reduces the chance of contamination and postoperative infection. , which improves the quality of the operation, but the flusher also needs to be operated by a special person when it is used, which increases the labor cost during use, and the flow adjustment can only be adjusted by feeling, and the flow rate is not constant, which increases the discomfort and risk of the patient. After the liquid is used up, it is necessary to repeatedly open the regulating valve to enter the liquid, which distracts the doctor's attention from observing the field of vision, brings risks to the diagnosis and treatment process, and needs to replenish the liquid at any time. When the liquid is replenished, the operation needs to be interrupted, which will bring discomfort to the patient.

[0005] Clinically, in some gastrointestinal endoscopic examinations, when doctors need to use the flushing device, they often use a common syringe connected to a catheter for direct use. The flushing fluid uses physiological saline, and the device also has flow adjustment. It is not constant, requires special personnel to operate, the amount of washing liquid is large, the operation time of gastroenteroscopy is long, and the temperature of washing liquid is low in winter, and the defect of irritation is large. In clinical use of this device, the operation time of gastroenteroscopy is about 15 minutes
