Assembled artificial heart biological valve treatment device for repeated replacement under minimally invasive surgery

Abstract

The invention relates to an assembled artificial heart biological valve treatment device for repeated replacement under minimally invasive surgery, which is characterized in that it comprises a base (1), a replaceable self-expanding biological valve support (2), wherein the base (1) and The replaceable self-expanding biological valve support (2) fits together. When the patient's biological valve decays and needs to be replaced again, the operation can be performed in a small incision and minimally invasive way, with low risk, short operation time, quick recovery of the patient, and avoiding the large trauma of the conventional method; The procedure of replacement surgery enables more patients to consider using biological valves during treatment, thereby avoiding the risks brought by life-long anticoagulation and significantly improving the quality of life of patients; The concept of assembly and replacement under minimally invasive surgery is a completely innovative idea with great application value.

Description

technical field [0001] The invention belongs to the field of medical clinical heart artificial valves, in particular to a biological valve device which can be easily and repeatedly replaced under minimally invasive surgery, and is used for treating various heart valve diseases. Background technique [0002] The most effective treatment for valvular heart disease is surgical replacement. Currently, there are two main types of artificial replacement valves: mechanical valves and biological valves, but both have their own shortcomings. The advantages of mechanical valves are good durability and generally do not need to be replaced repeatedly, but the disadvantage is that it is easy to cause thrombosis, so all patients with mechanical valve replacement need to take anticoagulant drugs for life after surgery, and thrombosis and bleeding caused by improper anticoagulation Complications such as these have brought many hidden dangers to the life of patients after surgery. Another t...

The advantages of mechanical valves are good durability and generally do not need to be replaced repeatedly, but the disadvantage is that it is easy to cause thrombosis, so all patients with mechanical valve replacement need to take anticoagulant drugs for life after surgery, and thrombosis and bleeding caused by improper anticoagulation Complications and other complications bring many hidden dangers to the life of patients after surgery

Another type of valve is a biological valve, which has the advantages of good hemodynamic effect and no need for life-long anticoagulation, so there are few long-term complications. Afterwards, it usually declines in about 15 years. At this time, the patient must undergo another operation for heart valve replacement. Due to the extensive adhesion of the tissue and unclear anatomical structure, the second heart operation will lead to more bleeding, difficult operation, and long operation time. The relatively high risk discourages many physicians and patients from opting for a bioprosthesis as a final decision
