The invention provides a valve conveying device, and belongs to the technical field of medical instruments. The valve conveying device comprises an inner pipe, an outer pipe, a transfer mechanism anda bendable mechanism, wherein the inner pipe is arranged in a shell; the transfer mechanism comprises a first operating assembly; the bendable mechanism comprises a bendable assembly and a second operating assembly connected to the bendable assembly; the second operating assembly is independent from the first operating assembly and is used for bending the bendable assembly by a required angle, anda first operating end of the first operating assembly and a second operating end of the second operating assembly are exposed outside the shell. According to the valve conveying device provided by the invention, a doctor can operate the second operating end to regulate an integral angle of a valve, and meanwhile, the first operating assembly and the second operating assembly are independently arranged, so that the doctor can respectively or simultaneously regulate the position and angle of the valve, so as to adapt to more types of patients.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a valve delivery device. Background technique [0002] Heart valve disease is a common heart disease in my country, artificial heart valve replacement is the main means and the most effective way to treat heart valve disease. When performing artificial heart valve replacement, interventional surgery is required, and the valve delivery system is used to deliver the valve support to the center of the valve to be treated. [0003] For example, the artificial heart valve delivery system in the prior art includes an inner tube, an outer tube, a handle housing, an adjustable bending mechanism and a transfer mechanism. Wherein, the outer tube is sheathed outside the inner tube, and the proximal end and the distal end of the inner tube respectively correspond to the proximal end and the distal end of the outer tube that can extend out. The transfer mechanism is used to drive th...
