Device and method for cutting drainage tube

Abstract

The invention provides a device and a method for cutting a drainage tube. The device comprises a base, a cutting knife and a fastening-releasing device, wherein the fastening-releasing device is connected to the base, and capable of fixing and releasing the drainage tube relative to the base; the cutting knife is used for cutting the drainage tube; the base is provided with a groove in the longitudinal direction; a head part used for placing the cutting knife is arranged at one end in the longitudinal direction, of the base, the head part is provided with a through hole in the longitudinal direction of the base, and the through hole communicates with the groove, and is used for penetrating through the drainage tube, so that the drainage tube is placed in the groove; and scales are distributed on one side opposite to the head part, of the base, in the longitudinal direction of the groove, and used for determining a length of the drainage tube. According to the device for cutting the drainage tube, use personnel can cut the drainage tube with a corresponding length according to the needed length. Therefore, only a certain number of drainage tubes with enough lengths need to be stored in a hospital, one drainage tube with a needed length is cut during use, and lots of drainage tubes with various types have no need to be stored.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a drainage tube cutting device. Background technique [0002] "Biliary drainage tube", also known as "biliary drainage tube", is used together with an endoscope to temporarily drain bile by inserting an indwelling drainage tube. The bile duct drainage tube is placed into the bile duct through the duodenal papilla under endoscopy to establish a drainage path for bile. It is mainly used for bile drainage after endoscopic biliary stone surgery and endoscopic cholecystectomy. It is a simple and effective It is mainly used to reduce jaundice after benign and malignant bile duct obstruction, and to diagnose and treat suppurative cholangitis and other diseases that require bile duct drainage. With the development of therapeutic ERCP (endoscopic retrograde cholangiopancreatography), endoscopic bile duct drainage is the first choice for bile duct drainage due to its minimal t...
