Embodiment Construction

[0044] The present invention will be further explained below in conjunction with specific examples.

[0045] Such as figure 2 , image 3 As shown, the artificial heart valve holder of the present invention (hereinafter referred to as the holder) includes a catheter 1, a sleeve 5, an inner core 9, a guide cone 2, a valve fixing member 4, a limiting device and a second holding part 8.

[0046]The inner core 9 slides and penetrates into the catheter 1. The inner core 9 is cylindrical and has a channel 15 along the axial direction. The outer surface of the cylindrical inner core 9 is smooth, making the relative movement between the inner core 9 and the catheter 1 easier. It is flexible and convenient for the release and recovery of the artificial heart valve. There is no special requirement for the material of the inner core. It can be metal, plastic and other materials that meet the requirements of medical devices, but it should have a certain hardness to ensure its basic push...

Abstract

The invention discloses an artificial heart valve holder, which comprises: a catheter; a first gripping part, which is fixed with the catheter; an inner core, which slides through the catheter; is the proximal end extending out of the catheter; the guide cone is outside the catheter and is connected to the distal end of the inner core; the valve fixture is fixed on the inner core and is adjacent to the distal end of the inner core The part between the guide cone and the valve fixing part is the installation section for placing the artificial heart valve; the limit device is sleeved on the inner core, and is used for sliding positioning between the inner core and the catheter. The invention provides a gripper for a radially compressible artificial heart valve, which can be operated with one hand, and is convenient for doctors to quickly and accurately locate the artificial heart valve to the implantation position.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an artificial heart valve holder. Background technique [0002] When the patient's own heart valve (mitral valve, tricuspid valve, aortic valve or pulmonary valve) is mutated due to congenital or acquired diseases, causing the valve to fail to open and close normally, it will affect healthy life and even life. Heart valve replacement (valve replacement with an artificial heart valve) has become a routine surgical option for the treatment of heart valve disease. [0003] Due to the relatively mature surgical technique and high success rate of surgery, surgical methods still account for a large proportion in the treatment of heart valve diseases. [0004] The artificial heart valves currently used for surgical replacement are mostly artificial heart valves with a rigid annulus (such as the artificial heart valves involved in the Chinese patent document with the publication number CN...
