Abstract

The invention discloses a large-flux magnetic positioning sensor, and relates to the technical field of magnetic positioning sensors. The large-flux magnetic positioning sensor comprises a magnetic core and an electronic wire wound on the magnetic core, the magnetic core adopts a large-diameter metal magnetic core wire treated by a key heat treatment process; a magnetic core wire coating is arranged on the surface of the metal magnetic core wire. The amplitude of alternating current voltage signals output by the magnetic positioning sensor is improved, the magnetic flux passing through the magnetic positioning sensor is increased, namely, the inductance value is increased, so that the positioning precision of the magnetic positioning sensor is improved, meanwhile, the requirements of small size and low power consumption of the magnetic positioning sensor are met, and the magnetic positioning sensor has the broadband characteristic and the strong magnetic field resistance characteristic.

Description

technical field [0001] The invention relates to the technical field of magnetic positioning sensors, in particular to a high-flux magnetic positioning sensor. Background technique [0002] Nowadays, electromagnetic positioning and navigation technology is increasingly used in clinical minimally invasive interventional procedures such as cardiac ablation, pulmonary bronchial ablation, and robotic puncture and biopsy. In traditional electrophysiological interventional surgery, professional doctors can only perform long-term operations in combination with X-rays, which not only causes a lot of radiation damage to doctors and patients, but also reduces the accuracy and safety of surgery due to low positioning accuracy. The magnetic positioning sensor is placed at the end of the positionable guide. By detecting the spatial magnetic field intensity, the accurate correspondence between the medical three-dimensional image and the human physiological mechanism can be realized. The po...
