Biodegradable fishhook |
摘要 |
A fishhook is described which disintegrates upon standing for prolonged periods of time in an aqueous environment such as within biological tissue. In one embodiment, the fishhook comprises a biodegradable polymeric hook-shaped structure with at least one metal tip affixed thereto providing a sharp piercing element. Upon exposure to the chemical environment of the fish's tissue the polymer biodegrades. In another embodiment, a substantially insoluble or non-biodegradable body portion of the hook has a separable point and barb portion affixed to the insoluble portion by means of a biodegradable adhesive. When the fishhook penetrates the fish's tissue, the solvents and/or enzymes present in the tissue environment causes the adhesive to release the barb and/or the point of the fishhook and the fish may shed the disintegrated fragments. In yet another embodiment, the entire fishhook is fabricated from a biodegradable polymer such as polylactide or polyglycolide or a copolymer thereof.
