Detection device and interventional treatment apparatus

Abstract

The application discloses a detection device which is used for magnetic positioning and pressure detection of a duct. The detection device comprises a supporting column (1) arranged at the far end ofthe duct, and a deforming body (2) arranged at the far end of the supporting column (1), wherein the deforming body (2) is provided with a spiral groove (3) which spirally extends, and is also provided with axial accommodation spaces (4), the axial accommodation spaces (4) extend to the supporting column (1) form the deforming body (2), and an optical sensor (5) is arranged in each axial accommodation space (4); and a magnetic positioning sensor (6) is arranged in the supporting column (1). The application further provides an interventional treatment apparatus. The detection device and the interventional treatment apparatus provided by the application are simple to assemble, low in structure accuracy requirement and simple in pressure test method, and can effectively assist operators to perform surgery operations.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a detection device and an interventional treatment device. Background technique [0002] Radiofrequency ablation is to send a catheter with electrodes into a specific part of the heart cavity through blood vessels, and release radiofrequency current to cause coagulation necrosis of local endocardium and subendocardium, so as to block the abnormal conduction bundle and origin point of tachyarrhythmia Interventional technology. The traditional mapping method for arrhythmia treated by radiofrequency ablation is to directly record multi-conductor intracardiac electrograms, and locate them according to the shape, amplitude and time relationship of local potentials. For simple arrhythmias, this method has the advantages of simplicity, practicality and speed, but it is often difficult for complex arrhythmias. Therefore, in recent years, a new mapping and positioning ...

AI Technical Summary

Problems solved by technology

One of the major problems of radiofrequency ablation is that it is difficult to control the degree of adhesion between the catheter and the endocardium. Insufficient ablation may easily lead to impermeable damage, edema, prolonged operation time, and high recurrence rate, while excessive ablation will lead to the transition of the heart chamber wall. Injury, leading to a greatly increased incidence of cardiac tamponade, esophageal injury, Pop, etc.

At present, it is difficult to determine the contact force between the tip of the ablation catheter and the tissue. It can only be judged by the doctor's hand feel and experience, catheter positioning information, X-ray images, etc., and the error is relatively large.
