Patent ID: 7621917

Claim:
A bone recovery device for recovering bone fragments during surgery, comprising: a front canula, an axial main body having an axial cavity passing through it with a proximal end and a distal end, a front connector incorporating an axial passage and adapted to be fixed to the distal end of said main body, a filter having a filtering wall of generally cylindrical tubular shape and adapted to be retained in position in said main body, an annular cavity left free around said filter between said cylindrical filtering wall of said filter and internal lateral faces of said axial main body and said front connector, in which device: said main body comprises a radial outlet communicating with said annular cavity and adapted to be connected to a suction device, a scraper piston is provided, having a piston rod that passes through the proximal end of said main body, and having a piston head adapted to slide axially inside said cylindrical tubular filter, said piston head blocking the proximal end of said filter at all times during use of said bone recovery device during a recovery phase and emptying said filter on axial movement in translation toward said distal end, the piston head being connected to the piston rod so that the piston head is moved back and forth by a first axial translation of the piston rod toward a distal end of the filter and by a second axial translation of the piston rod toward a proximal end of the filter.
