Embodiment Construction

[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0039] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directl...

Abstract

The invention relates to a force measuring device, which comprises a handle assembly, a pushing assembly and a force measuring assembly. The pushing assembly is located at a far end of the handle assembly, the pushing assembly is used for being connected with a cardiac apex gasket in a releasable mode, and the cardiac apex gasket is used for fixing a tether extending out of the heart outside the heart; the force measuring assembly respectively penetrates through the pushing assembly and the handle assembly; the force measuring assembly is provided with a tether channel for the tether to penetrate through, the tether sequentially penetrates through the apical apex gasket, the pushing assembly and the tether channel and penetrates out of the handle assembly, and the handle assembly can axially move relative to the force measuring assembly so as to adjust and measure the tension of the tether extending to penetrate through the tether channel and the handle assembly. According to the forcemeasuring device, the tension of the tether can be adjusted and measured by adjusting the axial distance between the handle assembly and the force measuring assembly, and the heart valve can be better fixed in the heart.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a force measuring device. Background technique [0002] Some known prosthetic heart valves (eg, prosthetic mitral valves) include one or more tethers that extend from the valve to the exterior of the heart and are secured to the heart's outer ventricular wall with an apical spacer. Through the binding force of the tether, the valve will not be squeezed into the atrium during systole, thereby reducing the risk of blood backflow from the mitral valve into the atrium. [0003] The tension of the tether determines how well the heart valve is secured. When the tether is loose, the heart valve cannot be pulled toward the apex by the tether. When the heart contracts, the blood flow from the ventricle hits the valve, and the heart valve moves toward the atrium, creating a gap between the native valve and the implanted heart valve. , resulting in paravalvular leakage, making the opera...
