Document Type and Number:
WIPO Patent Application WO/2023/173704
Kind Code:
A1
Abstract:
The present invention provides a fastening instrument, which is formed by woven string-like materials and comprises: a ring portion, which comprises a thread ring for a target tissue to pass through; a knot portion, which is connected to the ring portion, the knot portion being used for abutting against a bone; and an adjusting portion, which is connected to the ring portion to adjust the size of the thread ring. During use, the target tissue is fastened to the bone, and the knot portion formed by the woven string-like materials can produce certain deformation along with the surface shape of the bone when in contact with the bone, so as to reduce the gap, increase the contact area and hence improve the fastening effect between the tissue and the bone. The present invention further provides a manufacturing method for the fastening instrument, and a medical fastening device.
