Description
Technical Field
The application relates to the technical field of medical equipment, in particular to a stomach tube special for laparoscopic sleeve gastrectomy.
Background
Obesity is a very popular disease, and the number of people reaching the obesity diagnosis standard in China currently exceeds 1 hundred million. Obesity causes a lot of metabolic complications, including hypertension, diabetes, cardiovascular and cerebrovascular accidents, etc., but the conventional lifestyle control (including diet control, increasing exercise) and the use of weight-reducing drugs cannot achieve the ideal weight-reducing effect, and the improvement on the metabolic complications is not ideal. The weight-reducing operation is a weight-reducing mode which is gradually mature in recent years, the weight-reducing effect is good (usually, the excessive weight can be reduced by more than 80% in one year after the operation), the duration is long, and the metabolic complications are better improved, so that more and more patients select the weight-reducing operation as a means for treating obesity, at present, Europe and America are mature, the number of operation cases per year exceeds 20 ten thousand, and at present, the number of operation cases per year in China breaks through 1 ten thousand. The weight-reducing operation has a plurality of different operation types, wherein the sleeve gastrectomy has the characteristics of good weight-reducing effect, simple and convenient operation and high safety, the application rate is more than 90 percent at one degree, and the sleeve gastrectomy is the most widely applied weight-reducing operation type at present.
Sleeve gastrectomy involves the following key techniques: and (3) dissociating the greater curvature side of the stomach, placing a No. 32-36 stomach tube, and excising 80% of stomach bodies along the edge of the stomach tube by using a cutting anastomat. On the next day after the operation, the possibility of edge leakage is generally eliminated by aqueous radiography, or gastroscopy is performed during the operation (but the operation anesthesia time is required to be prolonged, and the detection rate is low). However, the contrast agent is very difficult to drink, which increases the pain of the patient, and the contrast is radioactive. The gastroscope is thin, can not block the pylorus and cardia, has the possibility of missed diagnosis, and the gastroscope also needs to pay, and is not cost-effective in addition to the human cost. The gastric tube in the prior art can only be used as a supporting tube and a mark for cutting, cannot be used for detecting lateral leakage, and some gastric tubes with electronic elements have higher cost and cannot be used repeatedly.
Therefore, a stomach tube special for laparoscopic sleeve gastrectomy needs to be developed urgently by those skilled in the art, the stomach tube can be used for conventional supporting and detecting incisal edge leakage, postoperative examination is reduced, operation anesthesia time is reduced, and operation safety of patients is improved.
