Devices for affixing sutures, grafts and tissues to bone, and soft tissues such as periosteum. In a first embodiment, the invention comprises a piton member (62) implantable within bone having a post or eyelet (64) formed thereon to which the suture or tissue may be attached. The piton member is designed to become more firmly secured within the bone when pressure is applied to a first axis pushing the piton member into the bone, but may be easily removed when such force is applied in a generally opposed direction. In a second embodiment, the invention comprises affixation devices (70, 80, 90) that are designed to detachably ensnare with periosteum. Such devices are provided with attachment structures, such as one post, eyelet or other means for securing sutures, grafts, synthetic materials or tissue.
L'invention concerne des dispositifs permettant de fixer des sutures, des greffes et des tissus sur un os et à des tissus mous tel que le périoste. Selon un premier mode de réalisation, l'invention comprend un élément de piton (62) implantable dans un os possédant une tige ou un oeillet (64) formé sur ladite tige, auquel la suture ou le tissu peut être fixé. L'élément de piton est conçu de façon à être plus solidement fixé dans l'os lorsque la pression appliquée à un premier axe pousse ledit élément de piton dans l'os, et à être facilement retiré lorsque ladite force est appliquée dans une direction généralement opposée. Selon un second mode de réalisation, l'invention comprend des dispositifs de fixation (70, 80, 90) conçus de façon à se loger, de manière libérable, dans le périoste. Ces dispositifs sont pourvus de structures de fixation, telles qu'une tige, un oeillet ou d'autres moyens de fixation de sutures, de greffes, de matériaux ou de tissus synthétiques.
