Device for selective biological synthesis of a bone tissue

摘要

Device for selective biological synthesis of a bone tissue including a screw for the stabilization of a fracture or of a porotic bone tissue, wherein said screw is arranged along an axis (X), substantially longitudinal with respect to said screw, and it is constituted by an extended body, from a first end or tip and from a second end or head, wherein at least said extended body and said second end or head include a longitudinal channel, wherein said extended body has at least one hole or slot, wherein said device includes a pin inserted into the longitudinal channel and provided with means for releasable connection with said screw, for reinforcing the device and for the releasable closure thereof.

主权项

1. A device for selective biological synthesis of a bone tissue comprising:
a screw for the stabilization of a fracture or of an osteoporotic bone tissue, wherein said screw is arranged along an axis (X), substantially longitudinal with respect to said screw itself, and comprising an extended body, a first end and a second end, wherein at least said extended body and said second end comprise a longitudinal channel, wherein said extended body of said screw comprises a portion having a substantially smooth outer surface having a plurality of elliptical holes, and a portion proximate to the first end having external threading and including a plurality of circular holes arranged between turns of said external threading, wherein said device comprises a pin, insertable into said longitudinal channel and provided with releasable connection means with said screw, for reinforcing the device and for the releasable closure of the same, and wherein said device comprises an injector of the cannulated type, comprising a lower end, suitable to be inserted into an injection system, and an upper end, suitable to be inserted into said longitudinal channel of said screw so as to obtain a selective injection through said circular or elliptical holes.
