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 a heart valve prosthesis holder which comprises a catheter, a first holding portion, an inner core, a guide cone, a valve fixing piece and a limit device. The first holding portion is fixed with the catheter. The inner core penetrates through the catheter in a sliding mode, one end of the inner core is a far end, and the other end of the inner core is a near end stretching out of the catheter. The guide cone is arranged on the outer portion of the catheter and is connected with the far end of the inner core. The valve fixing piece is fixed to the inner core and is close to the far end of the inner core, and the portion, between the guide cone and the valve fixing piece, of the inner core is a mounting section used for containing a heart valve prosthesis. The limit device is arranged on the inner core in a sleeved mode, and used for locating the inner core and the catheter in a sliding mode. The holder is provided for the heart valve prosthesis capable of being compressed in the radial direction and can be operated with one hand, and doctors can locate the heart valve prosthesis at an implantation position conveniently, fast and accurately.

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...
