Title:
VALVE REPAIR DEVICE AND FIXING MECHANISM FOR CLIP PIECE COMPONENT THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/103220
Kind Code:
A1
Abstract:
A valve repair device (1) and a fixing mechanism for a clip piece component (13), the valve repair device (1) comprising: a spacing element (11), an inner clip component (12), a clip piece component (13), an outer clip element (14), an outer frame component (15), and a cover material (16). The valve repair device (1) uses hinge structures at two positions, the spacing element (11) being hinged to the inner clip component (12) at the first position, and the inner clip component (12) being hinged to the U-shaped outer clip element (14) at the second position, so that less control force is required during clamping and thus precision control by a doctor is facilitated during operation. The integrally-formed U-shaped outer clip element (14) maintains, by means of the rigidity of outer clip arms (141, 142) thereof, continuous opposite clamping forces on the components/element (11, 12, 13) in the clamping space, and has a simpler clamping structure. Therefore, the clamping mode has a more stable clamping effect compared with the prior art in which an elastic clamping force is provided by a frame/strip-shaped piece, and has a simpler manufacture process compared with the prior art in which outer and inner clip arms formed by folding a metal woven material are used.
