Description

technical field

[0001] The invention belongs to the field of medical equipment, and relates to a valve support and an interventional heart prosthesis valve. Background technique

[0002] Cardiac prosthetic valves are artificially manufactured organs that can be implanted in the heart to replace the original heart valves and control the one-way flow of blood in each chamber of the heart. With the development of the national economy and the aggravation of population aging, in recent years, the incidence of valvular heart disease has gradually increased, and the incidence population is also gradually younger. For patients with severe valvular disease who are elderly, complicated with multiple organ diseases, have a history of thoracotomy, and poor heart function, interventional treatment of valvular heart disease has many advantages such as no need for thoracotomy, less trauma, less pain, and faster recovery. , has been favored by more and more patients.

Examples

Embodiment 3

[0130] In the present embodiment, the same structures as in the first embodiment are given the same reference numerals and the same descriptions are omitted.

[0131] Figure 25 It is a schematic diagram of the three-dimensional structure of the middle ring bracket of the third embodiment of the present invention, Figure 26 It is a cross-sectional structure diagram of the pulling ring of the third embodiment of the present invention.

[0132] Such as Figure 25 as well as Figure 26 As shown, the main difference between this embodiment and Embodiment 1 is that the pulling ring 126 of the middle ring is not in the shape of a raised semicircular ring, but is recessed in the middle ring 121, a through hole in a U-shaped structure, on the surface of the middle ring bracket 12 It is in the shape of two holes, and the pulling rope can pass through the U-shaped through hole through the two holes to complete the pulling effect. In this embodiment, the number of the middle ring pu...
