Background technology
The prevalence of heart failure increases year by year in recent years, becomes serious public health problem.China's heart failure prevalence is 0.9%, in the cause of disease coronary heart disease by 1980 36.8% rise to 2000 45.6%, occupy first of the various causes of disease.After acute myocardial infarction, the patient of nearly 20%-50% can develop into heart failure, particularly Anterior Wall Myocardial Infarction.After acute anterior wall myocardial infarction patients, myocardial necrosis and scarring subsequently, cause left ventricular remodeling, causes that left ventricle expands and Assessment of Left Ventricular Systolic Function declines.The important symbol of remodeling ventricle is exactly that locular wall tension variation and heart volume change.Thereby therefore mechanical minimizing bulk of left ventricle can alleviate locular wall tension force and improve remodeling ventricle, Here it is, and the left chamber of surgery subtracts the theoretical foundation of holding art.Hold the art history of existing more than 50 years although left chamber subtracts, surgery operating wound is larger, and makes clinical practice limited to having relatively high expectations of surgery patient.
Utility model content:
For the problems referred to above, this utility model provides a kind of medical cardiac tamponade thing.
This utility model comprises bracing frame and base, support frame as described above by multiple can developing unit, multiple fixing points, multiple umbrella frame shape poles and multiple cambered surface form, wherein every adjacent two umbrella frame shape poles are connected and composed and are inverted the bracing frame of umbrella shape and the umbrella of bracing frame along around to turning up by cambered surface, valgus angle is 0～90 °, the corresponding fixing point of one end connection of umbrella frame shape pole and the umbrella that fixing point rides over bracing frame are along upper, on each fixing point, being equipped with can developing unit, on each umbrella frame shape pole and fixing point, be all covered with macromolecule isolating membrane, the bottom of bracing frame is connected with base, the bottom of base is a plane.
The beneficial effects of the utility model: this utility model cardiac tamponade thing can pass through percutaneous intervening mode, this utility model cardiac tamponade thing is delivered in human heart by sheath pipe and induction system by intervention specifically, be implanted in heart, utilize blocking of isolating membrane, effectively reduce ventricular volume, reduce ventricle tension force, improve remodeling ventricle and patient's cardiac function.Overcome the shortcoming that traditional surgery wound is large.Size after the compression of this utility model cardiac tamponade thing can enter in the delivery sheath of 12～16Fr simultaneously, effectively reduces the wound otch of intervene operation.Also the elastic performance that has overcome existing wadding poor simultaneously, cardiac stimulus inner chamber; Development effect is not good, improves operation technique difficulty; And existing wadding structure stimulates the shortcoming of the apex of the heart etc.The implantation expansion of the cardiac tamponade thing in this utility model, compression implant enters heart sheath pipe, and be transported to after heart proper site along sheath pipe, release cardiac tamponade thing and utilize the memory characteristic of Ultimum Ti material to recover its dimensional structure, fit in cardiac lumen position by the superelastic properties of its material, particularly cardiac lumen is because disease is irregular, effectively avoid cardiac stimulus inner chamber, this utility model utilization simultaneously can developing unit improve the positioning performance in operation, reduce operating difficulty, and base adopts macromolecular elastomer material, effectively avoid the cardiac stimulus apex of the heart, and utilize blocking of isolating membrane, effectively reduce ventricular volume, and reduce ventricle tension force, to reach the therapeutic purposes of the cardiac function that improves remodeling ventricle and patient.
