Abstract

The invention discloses a guiding device in gastrectomy. The guiding device comprises a flexible traction tube and a flexible bent tube, the bent tube is connected with the traction tube, a plurality of sound holes are formed in the bent tube in the length direction, sound production parts are arranged in the sound holes, and the connecting line between any two sound holes is not parallel to the length direction of the bent tube. The bent tube is placed in the stomach by pulling the traction tube, the stomach is cut according to the shape of the bent tube, the bent tube is compressed when the cut position deviates, so that gas in the bent tube flows through the sound holes and triggers the sound production parts, and the sound production parts make a sound to prompt an operator; and in addition, the arrangement of the sound holes can avoid the situation that the stomach wall covers all the sound holes and sound cannot be produced. The guiding device can accurately position the resection position of the stomach, enables the shape of the remaining stomach bag to be more regular and controllable, and is simple in structure and easy to operate.

[0001] The invention relates to a guiding device in gastrectomy in the technical field of medical instruments. Background technique

[0002] The number of obese patients in the world has increased rapidly in the past 30 years, and obese patients are often combined with a variety of chronic diseases, which seriously affect the quality of life of patients. Laparoscopic sleeve gastrectomy is currently a commonly used method for the treatment of obesity, that is, about two-thirds of the stomach volume is removed along the greater curvature of the stomach, leaving a sleeve-shaped gastric pouch to reduce the patient's nutrient absorption of food. However, at present, the resection of the greater curvature of the stomach is only based on the doctor's experience, which often results in irregular and inaccurate volumes of the remaining gastric pouch, which affects the therapeutic effect.
