Self-adaptive guiding device and transcatheter treatment system

Abstract

The invention discloses a self-adaptive guiding device and a transcatheter treatment system.The self-adaptive guiding device comprises a hollow flexible catheter with a certain length, the flexible catheter is pre-shaped and bent towards different planes for at least five times along the central axis of the flexible catheter in the natural state, and the flexible catheter is bent towards the different planes along the central axis of the flexible catheter; the included angle between the two planes which are bent at a time and are closest to the far end is larger than 90 degrees, and the angle between the planes which are continuously bent at least four times is smaller than 90 degrees, so that at least part of the flexible tube body adapts to the shape of the aortic arch part. According to the self-adaptive guiding device and the transcatheter treatment system provided by the invention, the self-adaptability of the guiding device to blood vessels with complex anatomic forms such as the aortic arch part can be improved, the structure of the guiding device is simplified, and the use safety of instruments is improved; the situation that the guiding device needs a large avoiding space during use is avoided, tissue is prevented from entering an avoiding area in a filling mode, and it is ensured that the guiding device has a large operation adjusting space and an initial position which is more beneficial to adjustment.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an adaptive guiding device and a transcatheter treatment system. Background technique [0002] With the development of medical technology, interventional surgery is becoming more and more common, which is characterized by opening a small operating window on the patient's body surface, delivering catheter-like instruments to the treatment area along the vascular channel, establishing an in vitro-in vivo channel, and then This channel is sent into various treatment devices for interventional treatment. Among them, the device used to establish a channel from the outside to the body is called a guide device. For interventional treatment under different paths, the guide device needs to adapt to the shape of different blood vessels, and it is best to have a certain degree of self-adaptability. Under the premise of irreversible tissue damage, it can quickly and accurately r...
