Abstract

The invention discloses a guiding device in gastrectomy, which comprises a flexible traction tube and a flexible curved tube, the curved tube is connected with the traction tube, and a plurality of acoustic holes are arranged on the curved tube along the length direction, and each of the acoustic holes is provided with a plurality of acoustic holes. There are sound-emitting parts, and the connection line between any two sound holes is not parallel to the length direction of the elbow. By pulling the traction tube, the elbow is placed in the stomach, and the stomach is excised according to the shape of the elbow. When the excision position is offset, the elbow is compressed, so that the gas in the elbow flows through the sound hole and triggers the sound-producing part to produce sound. The component emits a sound to alert the operator; in addition, the arrangement of the sound holes can avoid the situation where the stomach wall covers all the sound holes and cannot produce sound. The invention can accurately locate the excision position of the stomach, so that the shape of the remaining gastric bag is more regular and controllable, and the structure is simple and easy to operate.

Description

technical field [0001] The invention relates to a guiding device in gastrectomy in the technical field of medical devices. Background technique [0002] The number of obese patients in the world has increased rapidly in the past 30 years, and obese patients are often associated with a variety of chronic diseases, which seriously affects 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 bag to reduce the patient's nutrient absorption of food. However, the current intraoperative resection of the greater curvature of the stomach is only based on the doctor's experience, which often results in irregularity and inaccurate volume of the remaining gastric bag, which affects the therapeutic effect. SUMMARY OF THE INVENTION [0003] The purpose of the present invention...
