Description

Drainage tube special for laparoscopic sleeve gastrectomy

Technical Field

The utility model belongs to the field of medical equipment, in particular to special drainage tube of peritoneoscope sleeve gastrectomy.

Background

Laparoscopic Sleeve Gastrectomy (LSG) can significantly reduce the body weight of obese patients and improve obesity-related metabolic syndrome by creating a sleeve-shaped or tubular stomach along the lesser curvature of the stomach, using its volume-limiting action and the endocrine-regulating mechanisms of the stomach to achieve the effects of weight loss, relief or treatment of obesity-related complications. Postoperative clinical evidence indicates that most patients can achieve good effects of losing weight and relieving complications without secondary operations, and sleeve gastrectomy has a series of advantages of simple operation, short operation time, few complications and the like, and gradually develops into an independent weight loss type.

At present, hospitals capable of carrying out laparoscopic sleeve gastrectomy are increased year by year, the number of cases is also increased year by year, a guide tube is generally needed in the operation, the guide tube extends into a pylorus after passing through a stomach, a laparoscopic scalpel is initially positioned, and a cutting reference line is fixed at a specific position in the laparoscopic sleeve gastrectomy. The existing guide tube inevitably generates a force of pulling backwards after being inserted into the pylorus, so that the guide tube moves back and forth in the pylorus and rubs to damage the pylorus. In addition, because the visual operation cannot be carried out, the insertion process of the guide tube is uncontrollable, the length of the guide tube extending into the body cannot be determined, and unnecessary damage to the human body is easily caused; the drainage flushing function and other functions can not be realized simultaneously in the operation, so that the performance of the existing guide tube is single, and the implementation of the laparoscopic sleeve gastrectomy is seriously influenced.
