    摘要： A cutting guide for spinal osteotomy comprises two polyhedral blocks, each polyhedral block comprising a respective tubular guide member, each tubular guide member extends from a proximal opening to a distal opening and has an axial cavity extending along a longitudinal axis; a connecting bridge which connects the two polyhedral blocks to each other and is adapted to surmount a spinous process of said vertebra; and contact members designed to match a corresponding plurality of points of contact on the patient's vertebra to define a unique coupling configuration of the cutting guide on the patient's vertebra. The two polyhedral blocks each comprise at least a first and a second slotted body, associated in pairs with a respective tubular guide member, arranged one opposite the other with respect to the corresponding tubular guide member associated therewith.

    摘要： A device for shaping and cutting a bone graft comprises a main body (2) extending along a longitudinal axis (X) from a lower end (2i) to an upper end (2s) and having inside it a housing (3) for the insertion of the bone graft (100) to be shaped, an upper opening (4), located at the upper end (2s), for the insertion of the bone graft (100) into the housing (3), a lower support (5) designed to support the bone graft and an upper surface (6) defining a cutting plane, placed at the upper end (2s) and containing said upper opening (4) which is inclined with respect to the longitudinal axis (X) by an angle (a) ranging between 90° and 30°, preferably between 90° and 60°.

    摘要： A surgical device includes a polyaxial surgical screw that includes an internally hollow tulip. The tulip includes two elongated rods which are parallel and mutually spaced apart, each elongated rod protruding from a side wall of the tulip and extending away from a first end of the tulip in a direction opposite to a second end of the tulip. The rods define a channel in communication with the first end for accessing the interior of the tulip. A locking unit can be reversibly mounted on the polyaxial surgical screw. The locking unit includes a tubular body which has an inner cavity and is adapted to be fitted about the elongated rods during a configuration of use of the surgical device. The tubular body has two mutually opposite protrusions which project into the inner cavity that are configured to face the channel and be mutually interposed.

    摘要： A template for measuring the cross section of a graft comprises a first half-body and a second half-body. The two half-bodies are mutually secured such that they can rotate the one with respect to the other around an axis, each one of the two half-bodies comprises a plurality of openings having known and different sizes, each one of the openings of the two half-bodies is open toward the outside through an at least partially radial slot. The two half-bodies can rotate the one with respect to the other around the axis between an open position and a closed position and vice versa. In the open position the slots of the first half-body axially coincide with the slots of the second half-body, and in the closed position the openings of the first half-body axially coincide with the openings of the second half-body.
