Picking manner and picking instrument of ligament transplantation piece

摘要

(57) Abstract In order to form the knee ligament for revision and supplementation, the kneecap bone of the knee of the patient, in order to extract the owner-occupied home system which is picked from the kneecap tendon, and the tibia from the patient, the kneecap bone reamer guide (16), with the tibia reamer guide, and these guides the reamer for the throwaway which is used (10) with picking manner of the ligament transplantation piece which uses the picking device of the new combination which is included is offered. As for the new picking device, being piled up on the kneecap bone, in order for it to be possible to demarcate the guide path in order in order to pass by the outside of the aforementioned kneecap bone, to guide the movement of the reamer in order that the kneecap bone reamer guide whose it is possible in the kneecap bone of the aforementioned patient to install in clamp expression, (16), it forms the kneecap bone plug junction to the portion of the tendon in order to pass by the aforementioned guide path, after the reamer for the throwaway which Drive possibly is designed (removes 10), and (the aforementioned reamer, removing the aforementioned kneecap bone reamer guide) the tibia of the patientBeing the tibia reamer guide who can install in clamp expression, in order in general straight line there is no, at the same time to pass by the outer part margin of the aforementioned tibia vis-a-vis with the aforementioned kneecap bone plug and the portion of the tendon of aforementioned long sun/size which were picked, to have the said tibia reamer guide who demarcates another guide path which guides the movement of the aforementioned reamer or another reamer, the aforementioned kneecap bone plug and portion of the tendon of aforementioned long sun/size to be sent into the aforementioned reamer or the reamer classified by aforementioned, after that, by in order to pass by the path of the aforementioned tibia reamer guide, Drive latter,The tibia plug junction to the portion of the tendon of aforementioned long sun/size as one unit being formed, the bone - kneecap ligament - bone transplantation piece is formed.
