| 摘要 |
A synthetic material is disclosed, which is constituted by a copolymer of D, L-lactide and epsi-caprolactone (which itself is characterized by lower degradation times than those obtainable with copolymers of L-lactic acid and epsi-caprolactone), obtained by using as reaction control agent a sugar dianhyide with non-toxic characteristics. The use of suar dianhydrde in the reaction has a considerable control effect on the molecular weight of the copolymer and, thanks to its low molecular weight, this copolymer is characterized by extreraely short resorption times, in the order for the example of one or two months. The copolymer is used as covering clement to be placed around tendon sutures and/or nerve tracts with the aim of preventing formation of scarry adherences between the suture lines and the soft surrounding tissues. |
