Embodiment Construction

[0014] In Fig. 1-3, the human in vivo Oddi sphincter myoelectricity and biliary dynamics simultaneous phase detection catheter includes a catheter body 1, the catheter body 1 is a hollow tube with openings at both ends, and its head 2 is fixedly connected with an introduction end 14. A through hole 3 is opened on the introduction end 14, and the distance between the through hole 3 and the top end of the head 2 of the catheter body 1 is 10mm. Along the radial direction of the catheter, three holes 11 (12, 13) are respectively provided on the outer tube wall of the head 2 of the catheter body 1, and the distance between the hole 11 closest to the introduction end 14 and the top end of the introduction end 14 is 11mm . The inside of the catheter body 1 runs through the entire catheter body 1, and is provided with a liquid perfusion tube 5 and two electrode channels 6 (7). A hole 12 on the outer wall of the head 2 of the main body 1; platinum wires 8 are respectively arranged in ...

Abstract

Disclosed is a canal with a hollow body for in-vivo Oddi sphincter myoelectricity and biliary dynamic in-phase detection. Three holes communicated with inside of the canal are arranged on the head wall axially, a liquid infusion channel and two electrode channels are arranged inside the hollow canal, the water inlet of liquid infusion channel is set in end portion of the canal body while the water outlet on the conduit body wall is a hole; a platinum wire is arranged inside the electrode channel, with one end of which threaded out of the tail of the canal body and the other end of which passes through two holes on the canal body head wall and wind around the external surface of the conduit body to form into two electrodes; a leading-in end having a through hole is fixed to the head of the canal body. The conduit has simple structure and can record in-vivo Oddi sphincter myoelectricity signal and biliary dynamic changes directly, effectively and accurately.

Description

technical field [0001] The invention belongs to the fields of clinical medicine and basic medicine, and relates to a human in vivo Oddi sphincter myoelectricity and biliary dynamics contact type simultaneous phase detection catheter. Background technique [0002] The sphincter of oddi (SO) is one of the most complex organs in the human body. So far, many of its basic problems are still not understood by people. The clinical judgment of SO function is still based on limited previous experience. The diagnosis of SO-related diseases basically relies on clinical symptoms and X-ray examinations, and there is still a lack of means or methods for directly detecting and judging SO functions. Therefore, there is an urgent clinical need for an effective means or method that can accurately judge SO function before surgery, so as to make a clear diagnosis and choose a reasonable surgical method. The most direct and exact way to judge the function of SO is to directly pick up the signal...
