Title:
FIXING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/210795
Kind Code:
A1
Abstract:
A fixing structure according to the present invention has: a porous sheet body (2) constituted by a non-absorbent material having biocompatibility; a cylindrical insertion part (4) for guiding an insertion member from inside a living body to outside the living body; a clamping part (5) that clamps, in the thickness direction of the sheet body (2), a portion surrounding an opening in the sheet body (2), and that is fixed to the insertion part (4); and a fixing strand (33) constituted by a strand sewn onto the sheet body (2) so as to fix the sheet body (2) and the clamping part (5). The fixing strand (33) is structured so as to be sewn onto the surface of the sheet body (2) so as to form a concave-convex structure serving as resistance against relative movement with respect to a target site of the living body through which the insertion member is inserted, with respect to the direction of extension of the sheet body (2). Such a structure makes it possible to provide a fixing structure with which it is possible to inhibit entry of bacteria and inhibit misalignment with respect to the target site.
