Abstract
A device for shaping and cutting a bone graft comprises a main body extending along a longitudinal axis from a lower end to an upper end and having inside it a housing for the insertion of the bone graft to be shaped, an upper opening located at the upper end for the insertion of the bone graft into the housing, a lower support designed to support the bone graft, and an upper surface defining a cutting plane placed at the upper end and containing said upper opening, wherein the cutting plane is inclined with respect to the longitudinal axis by an angle ranging between 90° and 30°, preferably between 90° and 60°.
Core Innovation
The invention is a bone-graft shaping and cutting kit comprising a device with a lower support and interchangeable main bodies. Each main body has a housing for insertion of a bone graft and an upper surface defining a cutting plane. The upper surfaces have different inclinations relative to their longitudinal axes, with each angle being at least 30 and less than 90.
The described configuration also includes an adjustable support, structures for retaining and positioning the graft, and slits with graduated scales indicating cutting height. The partial content does not include the background section, so the problem being solved is not explicitly described there. It states that the device enables precise back-table shaping, improves handling and graft-size selection, and reduces operating time while avoiding damage to the implant during shaping.
Claims Coverage
The provided relevant claims identify one independent claim, claim 1, which covers one main inventive feature.
Interchangeable main bodies with differently inclined cutting surfaces
A kit for shaping and cutting a bone graft comprising a lower support and a plurality of interchangeable main bodies. Each main body has a housing for insertion of the bone graft and an upper surface defining a cutting plane, inclined relative to the longitudinal axis by an angle greater than or equal to 30 and less than 90. The inclination differs among the main bodies.
The independent claim covers a bone-graft shaping and cutting kit whose interchangeable main bodies provide housings and cutting planes with different inclinations within the stated angle range.
Stated Advantages
Enables precise back-table shaping of bone grafts.
Improves handling and graft-size selection.
Reduces operating time and avoids damage to the implant during shaping.
Documented Applications
Back-table shaping and cutting of bone grafts.
Trephine-based bone-graft extraction, including the described use of an adapter and stabilizer for poor-quality bone.
