Abstract

The invention discloses a brushless DC direct drive motor for an OCT detection device. The motor comprises a permanent magnet, a multi-pole winding stator, a Hall sensor, a motor shell, a direct drivemotor driver, and a rotary shaft, wherein the permanent magnet is fixed on the rotary shaft, the rotary shaft is provided with a through hole penetrating the axis of the rotary shaft, the rotary shaft comprises a first rotary shaft end with a slip ring adapter interface and a second rotary shaft end with a guide tube adapter interface, the multi-pole winding stator, a position sensor and the direct drive motor driver are fixed on a motor bearing, and the Hall sensor is used for detecting a position of a magnetic pole of the permanent magnet on the rotary shaft relative to the multi-pole winding stator and controls a direction of a current input into each electrode of the multi-pole winding stator through the direct drive motor driver. The invention further discloses an OCT detection device direct drive module using the brushless DC direct drive motor, an OCT detection device drive equipment, and an OCT detection device assembly. Through adoption of the brushless DC direct drive motorfor the OCT detection device, the mechanical structure and electrical control are easy, so that assembling and debugging are convenient.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a brushless DC direct drive motor applied to OCT equipment, and an OCT direct drive module and OCT equipment manufactured using the brushless DC direct drive motor. Background technique [0002] OCT (Optical Coherence tomography, optical coherence tomography) medical clinical application equipment needs to be equipped with a catheter probe. From the analysis of the working principle of the probe, the infrared laser of the detection arm needs to be projected to the detection point through the high-speed rotating drive device to drive the prism assembly, and at the same time, the reflected light of the detection object is received by the prism and returns along the original optical path. Every time the guide wire rotates a circle, the infrared light emitted by the prism is equivalent to completing a 360-degree circular scan on a plane perpendicular to the rotation axis. According ...
