Abstract

The invention discloses a noninvasive valve fixator, comprising a fixing body; the bottom of the fixing body is in single valve shape, in tricuspid valve shape or in bicuspid valve shape. The middle of the fixing body is provided with a suction cavity which is connected with a suction device. Suction holes are arranged between the bottom of the fixing body and the suction cavity in communicated manner. The cross section of each suction hole is in horn shape. Each suction hole comprises a suction tail port in one end of the inside of the suction cavity and a suction front port in the bottom of the fixing body; each suction hole decreases gradually in size from the suction front port to the suction tail port. The suction tail port of each suction hole decreases gradually in size from the edge of the fixing body to the suction hole below the suction cavity. The noninvasive valve fixator is simple in structure; different specifications can be designed according to different application environments to meet different users; the noninvasive valve fixator is suitable for fixing the valve in noninvasive manner, and is suitable for use in cardiac valve surgery.

Description

technical field [0001] The invention relates to the technical field of structural design of heart valve treatment auxiliary equipment, in particular to a non-invasive valve fixing device. Background technique [0002] A valve is a membrane-like structure that can open and close in the organs of humans or some animals. A valve between the heart's four atria (chambers) that passively opens and closes to keep blood circulating in one direction. The role valves play in the heart's never-ending activity of circulating blood is as common as it is critical; valves are gatekeepers, preventing backflow of blood into the ventricles that have just left. There are valves between the atria and ventricles, and between the ventricles and the blood vessels that leave them. After the blood flows through, the valves close and the heartbeat sounds. [0003] With the development of medical technology, the treatment of valve lesions is imminent. Human heart valve replacement surgery through ...
