Description

Universal heart valvulopathy interventional instrument stabilizer

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a universal heart valvular disease interventional instrument stabilizer.

Background

The heart valve is a one-way valve structure between an atrium and a ventricle, and ensures that blood flows from the atrium to the ventricle. The normal valve structure includes two portions, a leaflet and an annulus. Valvular disease, typically of the type of valve stenosis/insufficiency, occurs when the anatomy and/or function of the annulus or leaflets is disrupted due to aging, disease, etc. Once a stenosis and/or insufficiency of the valve occurs, normal blood flow is affected and abnormal hemodynamic changes burden the heart, ultimately leading to heart failure. Valvular heart disease seriously affects patient health and quality of life, and therefore, sufficient attention needs to be paid.

With the aging population getting worse, valvular heart disease has become a non-negligible disease burden in our country. Although traditional surgical open valve repair or replacement procedures are the standard treatment for valvular heart disease, patients of advanced age and at high risk as evaluated by surgery often cannot tolerate surgical procedures due to the complexity of the disease spectrum in our country. In recent years, the rapid development of domestic and foreign transcatheter interventional therapy becomes an important treatment method for high risk groups of surgical operations. Currently, transcatheter interventions on mitral, aortic, and pulmonary valves are common, but treatment for tricuspid disease is still in its early stages. Due to the large diameter of the tricuspid valve, the anatomical location is adjacent to the right coronary artery, and the lack of calcification of the valve, annulus, greatly limits the progression of transcatheter interventions to treat tricuspid valve disease. The current tricuspid valve registration research shows that the cardiac output of patients at high risk after selected surgical operation receives NovelGate technical treatment is obviously increased within 3-6 months in a short period. In our country, the primary clinical practice of applying Lux-Valve transcatheter artificial tricuspid Valve replacement proves that the technology is safe and effective, and postoperative ultrasound prompts that the Valve position is good and the Valve orifice has no regurgitation. Because the Lux-Valve artificial Valve is fixed at the anterior Valve of the tricuspid Valve and the interventricular position through the hook and the anchoring device, compared with the radial supporting force of the traditional artificial Valve, the risk of atrioventricular block after operation is greatly reduced. Therefore, Lux-Valve is expected to become an important treatment means for tricuspid insufficiency in the future.

The existing transcatheter interventional instruments are all operated by hands, and operators need to adjust the operation of the instruments according to different operation approaches, patient positions and disease severity. The handheld instrument influences the accuracy of operating instruments of an operator to a certain extent and increases the operation risk. Especially in transcatheter interventional manual tricuspid Valve replacement, the pericardium, heart and right atrium are exposed through the axillary midline horizontal intercostal incision, and the right atrium approach and tricuspid Valve annulus level are not in a straight line, so the front end of the catheter of the Lux-Valve delivery device is designed to be an angle-bending adjustable structure. Because the front end of the delivery catheter forms a certain angle with the delivery system, the moving direction of the hand-held instrument end of the operator and the moving direction of the front end of the catheter in the atrium are not on the same axis. Although this design is anatomically correct, when the operator needs to advance or retract the catheter tip horizontally at the valve annulus to determine the optimal valve release position, the hand-held operation is often difficult to grasp and 1-2 assistant is needed to assist the operation. If the operator directly conveys the front end of the catheter blindly along the end direction of the handheld instrument, the valve is likely to be not firmly fixed, serious complications such as displacement after release, paravalvular leakage, heart rupture and perforation and the like occur, and even the operation is directly failed. This disadvantage causes inconvenience to the surgeon and limits the widespread use of this technique.
