Universal intervention instrument stabilizer for valvular heart disease

Abstract

The invention provides an universal intervention instrument stabilizer for valvular heart disease, which comprises a base, a plane rotating device, a mechanical arm, a sliding rail, a supporting platform, a clamping jaw and a joint capable of rotating universally, the base is connected with the plane rotating device, the plane rotating device is connected with the mechanical arm, the mechanical arm extends away from the plane rotating device and capable of keeping a bending shape, the top end of the mechanical arm is connected with a sliding rail through one joint, the supporting platform is slidably arranged in the sliding rail, and the supporting platform is connected with the clamping jaw through the other joint. According to the universal intervention instrument stabilizer for valvular heart disease, an intervention instrument can be assisted to keep in stable during an interventional operation, and particularly can ensure that the movement direction of an instrument is consistent with the bending direction of the front end of a catheter when Lux-Valve is applied to transcatheter tricuspid valve replacement, so that the surgeon is helped to control the intervention instrument, conveying and releasing of the artificial valve are completed, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a general-purpose stabilizer for heart valve disease interventional devices. Background technique [0002] The heart valve is a one-way "valve" structure between the atrium and the ventricle, which ensures blood flow from the atrium to the ventricle. A normal valve structure consists of two parts: leaflets and annulus. When the physiological structure and / or function of the valve annulus or valve leaflets are damaged due to factors such as aging and disease, valvular disease occurs, and its type is usually valvular stenosis / regurgitation. Once valvular stenosis and / or regurgitation occurs, it will affect normal blood flow, and abnormal hemodynamic changes will increase the burden on the heart, which will eventually lead to heart failure. Heart valve disease seriously affects the health and quality of life of patients, so it needs to be given enough attention...

AI Technical Summary

Problems solved by technology

Although such a design conforms to the characteristics of human anatomy, when the operator needs the front end of the catheter to advance or retreat at the level of the annulus to determine the optimal valve release position, it is often difficult to grasp the direction of the hand-held operation, and 1-2 assistants are required to assist in the operation

If the operator blindly transports the front end of the catheter directly along the direction of the hand-held instrument end, it is likely to cause the valve to be unstable, shift after release, paravalvular leakage, cardiac rupture and perforation and other serious complications, and even directly lead to surgical failure.

This shortcoming is inconvenient for the operator and limits the wide application of the technique
