Bending control handle and interventional system

Abstract

The present invention provides a bending control handle and an interventional system. The bending control handle includes a driving part, a circumferential indication part, a transmission part and a bending control line connecting part. The bending control handle defines an axis. The driving part and the circumferential indication part are both configured so as to be rotatable circumferentially around the axis, and the bending control line connecting part is configured so as to be translatable along the axis. The transmission part is configured to convert the circumferential rotation of the driving part into both the translation of the bending control line connecting part along the axis and circumferential rotation of the circumferential indication part. An amount of the translation of the bending control line connecting part along the axis is in a predetermined ratio to an amount of the circumferential rotation of the circumferential indication part. With this arrangement, the circumferential indication part can provide an indication simply by its circumferential movement, thereby effecting space savings for the arrangement of other components of the bending control handle.
