The bone recovery device of the invention comprises an axial main body
with an axial cavity passing through it, a front connector incorporating
an axial passage and adapted to be fixed to the main body, a filter with
a tubular filtering wall adapted to be fitted into the main body, and a
scraper piston that slides inside the filter. The scraper piston blocks
the end of the filter, and a radial outlet is provided in the axial main
body, with an annular cavity left free around the filter between the
filter and the axial main body. A canula is inserted into the distal end
of the filter. The recovery device may therefore be used to recover bone
retained by the filter during aspiration through the canula by the radial
outlet, and bone fragments may be extracted by sliding the piston and
withdrawing the canula. The recovery device may therefore be used several
times without demounting it.
