Embodiment Construction

[0036] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, implementations of the application; and the structures shown in the drawings are only schematic and do not represent real objects. It should be noted that, based on these embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art belong to the protection scope of the present application.

[0037]In this article, the term "head (end)" indicates the positional relationship of the entire system towards the valve leaflet, but it does not mean that it must be oriented towards a certain fixed direction in actual installation operations, but only to show the positional relationship or linking relationship between the various components . Similarly, postoperative "tail (end)", "front (end)", "upper (side)", "lower (side)" and so on do not constitute...

Abstract

The invention discloses a general heart valve interventional shaping system, which comprises a clip, a delivery catheter system, a deflection system, an opening and closing system, a locking system, a releasing system and a secondary clamping system. The present invention can be applied to various valvular regurgitation diseases in the heart, and has various surgical approaches, effectively solving the problem of valvular regurgitation of the heart; compared with traditional surgery, the advantages of minimally invasive surgery are obvious, no skin incision is required, and no scars are left. There is no need for cardiac arrest, extracorporeal circulation, or blood transfusion. Under the guidance of imaging equipment such as echocardiography and X-rays, valvuloplasty can be performed and its effect evaluated in a completely physiological state, which is convenient for the operator to treat reflux accurately and quickly. The valve can be treated while avoiding postoperative complications caused by traditional surgery for elderly and high-risk patients; complexity and reduce the cost of interventional devices.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a general heart valve interventional shaping system for interventional surgery to treat various valve regurgitation diseases. Background technique [0002] Valvular regurgitation is one of the most common heart diseases, mainly due to structural changes or functional changes in the ventricles, papillary muscles, valve rings and valve leaflets, resulting in a series of blood backflow caused by poor anastomosis of the anterior and posterior valve leaflets. pathophysiological changes. Drug treatment can improve the patient's symptoms to a certain extent, but the long-term effect is mediocre. Surgical valve repair or valve replacement is considered the standard treatment for the disease and has been shown to relieve symptoms and prolong life in patients. However, surgical operations generally need to be performed through thoracotomy, so they have the disadvantag...
