Guide wire length measuring device and measuring method for ERCP

Abstract

The invention discloses an embodiment of a guide wire length measuring device for ERCP, and the device comprises a fixing device which is fixedly disposed at the top end of a connecting short tube in a sleeving manner, and is provided with a central hole for a guide wire to pass through; the marking piece marks the guide wire; the measuring assembly comprises a fixing rod, a mounting box, a coil spring and a measuring line with scale marks; one end of the fixing rod is detachably inserted into the fixing device; the mounting box is of a hollow shell structure and is fixed to the other end of the fixing rod. The coil spring is arranged in the center in the mounting box; and one end of the measuring wire is fixed on the coil spring, and the other end of the measuring wire penetrates through the mounting box, extends outwards and is connected with two fixing clamps for simultaneously clamping the measuring wire and the guide wire. According to the guide wire length measuring device and method, rapid measurement of the length of the narrow section is achieved, and the problem that the length of the narrow section of the bile duct or the pancreatic duct is difficult to accurately measure when a patient is examined through existing endoscope retrograde pancreaticobiliary duct radiography is solved.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a guide wire length measuring device and a measuring method for ERCP. Background technique [0002] At present, medical devices refer to instruments, equipment, utensils and in vitro diagnostic reagents and other related similar items that are directly or indirectly used on the human body. During colonoscopy detection, ERCP (Encoscopic Retrograde Cholangio-Pancreatography, endoscopic retrograde cholangiopancreatography) detection is required for the narrow area of ​​the common bile duct between the duodenum and the bile duct of the patient. [0003] In the related art, when performing endoscopic retrograde cholangiopancreatography, it is necessary to use a guide wire to assist in delivering the incision knife to the bile duct or pancreatic duct in the patient's body for the next operation; wherein, the incision knife is used to inject contrast medium. During an...
