  • Publication number: 20080045622
    Abstract: It is intended to obtain a photocurable fixture for orthopedic surgery for which required strength can be obtained in a short period of time with visible light. A photocurable resin containing a urethane (meth)acrylate oligomer of the following formula (I) and a photopolymerization initiator which absorbs a light of 400 to 700 nm is prepared. This photocurable resin 4 is retained in a base material 3 to form a support material 5. The inside of this support material 5 is covered with a buffer material 6 and the outside is covered with a cover material 2, to obtain a splint material 1 as a fixture for orthopedic surgery. The buffer material 6 side is put on affected parts, and a bandage is wound over it, and then molding is carried out under irradiation with visible light. As the curing proceeds, a splint is obtained and the affected parts can be fixed. (in the formula (I), A denotes a diisocyanate residue, and each of X and Y denotes a (meth)acrylate residue having a hydroxy group.
