Embodiment 1

[0048] like figure 1 As shown, the present invention exemplarily provides an adjustable wire locking device, comprising: an operation assembly 1000, a handle 2000 and an implant 3000, the distal end of the operation assembly 1000 is detachably connected to the proximal end of the implant 3000, and the operation The proximal end of assembly 1000 is connected to handle 2000 .

[0049] Specifically, as figure 2As shown, in order to ensure the stable connection between the operating assembly 1000 and the implant 3000, the operating assembly 1000 includes: a connector 1100, the connector 1100 is detachably connected to the implant 3000, the connector 1100 is a hollow structure, and has a diameter of It gradually increases from proximal to distal. Further, in order to ensure that the device will not cause poisoning to human tissue after entering the human body, the connector 1100 is made of a biocompatible polymer material or metal material. Preferably, medical stainless steel i...

Embodiment 2

[0070] like Figure 12 as well as Figure 25-28 As shown, compared with the adjustable thread-locking device of the first embodiment, the adjustable thread-locking device provided by the present embodiment is different as follows:

[0071] The distal end of the first fixing member 1410 also protrudes with a limiting portion 1420 . The limiting portion 1420 is set as a cylindrical segment whose diameter is smaller than the width of the above-mentioned rectangular hole. Specifically, during operation, the rotating shaft 1400 will be connected to the winding member 3200 through the cooperation of the first fixing member 1410 and the second fixing member 3223, and then abut the stop member 3300 through the limiting portion 1420 of the rotating shaft 1400, Therefore, under the action of the rotating shaft 1400 , the stopper 3300 is controlled to move in a direction close to the second shell 3120 .

[0072] like Figure 14-28 As shown, compared with the implant 3000 of the first...

Abstract

The invention relates to an implant and an adjustable wire locking device. The implant comprises a shell assembly, a winding piece and a retainer. An opening is formed in the near end of the shell assembly; the winding piece is installed in the shell assembly, and the near end of the winding piece is movably arranged in the opening in a penetrating mode. The retainer is connected with the shell assembly, and a first limiting piece is arranged at the near end of the retainer; wherein the far end of the winding piece is far away from or close to the near end of the retainer, so that the first limiting piece is separated from the winding piece, or the first limiting piece is matched with the far end of the winding piece in an inserted mode. The adjustable wire locking device comprises the implant. According to the implant and the adjustable suture locking device, the suture winding degree can be adjusted in real time, so that the suture locking degree is proper.

Description

technical field [0001] The present application belongs to the technical field of medical devices, and in particular, relates to an implant and an adjustable wire locking device. Background technique [0002] Annulus dilatation, one of the most common causes of heart valve disease, can cause the valve leaflets to separate from each other during ventricular systole, creating gaps that can no longer close or coapt effectively, resulting in blood regurgitation and reduced blood output from the heart . [0003] Annuloplasty for annular expansion is an important procedure for mitral or tricuspid valve repair. The tricuspid valve orifice area is reduced to allow the leaflets to conform to each other during ventricular systole, thereby reducing or eliminating regurgitation. Although surgical annuloplasty can repair the valve annulus well, it has disadvantages such as large trauma, high risk, and slow patient recovery. In recent years, transcatheter minimally invasive intervention...
