AI Technical Summary

Technical Problem

Conventional image diagnostic catheters using intravascular ultrasound (IVUS) face issues with wear at the contact points of slip rings and brushes, leading to potential electrical noise due to abrasion powder, which can degrade image quality.

Method used

An image diagnostic apparatus with a slip ring and brush configuration where the contact portion is housed in a closed space filled with liquid lubricant, and a capturing section to manage abrasion powder, along with an integrally molded conductive ring and insulating member to reduce wear and noise.

Benefits of technology

This configuration effectively suppresses wear at the contact points of the slip ring and brush, reducing electrical noise and maintaining image quality by using liquid lubrication and integrated components to manage abrasion.

Abstract

An image diagnosis device according to the present disclosure can be connected to a diagnostic imaging catheter provided with an imaging unit including an ultrasonic transmission / reception unit, and can generate an intraluminal image. The image diagnosis device is provided with: a drive motor that can rotationally drive the imaging unit; a slip ring that can be electrically connected to the imaging unit and can rotate together with the imaging unit; and a brush that is electrically connected to the slip ring by contacting the slip ring. The slip ring and the contact part of the brush are disposed in a sealed space filled with a liquid lubricant.
