Title:
IMPLANTABLE INSTRUMENT HAVING VERTICAL DOUBLE-CONCAVE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/252463
Kind Code:
A1
Abstract:
An implantable instrument having a vertical double-concave structure. The implantable instrument comprises an upper disc surface (1), a lower disc surface (2) and a connecting part (3). The connecting part (3) is disposed between the upper disc surface (1) and the lower disc surface (2). The upper disc surface (1) and the lower disc surface (2) are respectively provided with concave disc surface structures (4) recessed toward the middle connecting part (3). The vertical double-concave structure can enhance the support performance and the deformation resistance of the implantable instrument, and compensate for the poor mechanical support performance of a degradable wire material; moreover, after heat treatment shaping, the implantable instrument can have certain stress recovery capability and elastic deformation capability, so that the implantable instrument can be restored to the shape. The friction force between the implantable instrument and a contact tissue surface can be enhanced, the wire diameter of the implantable instrument is reduced, and the sheath passing performance of the instrument is enhanced.
