초록 ▼

A bone cement mixing apparatus comprises a cylindrical syringe body which functions as a mixing chamber, a mixing element rotatably mounted in the mixing chamber and a drive for causing rotation of the mixing element. The drive includes a handle which is axially movable relative to the mixing chamber and a gear mechanism which couples the handle to the mixing element and translates linear handle motion into rotary mixing element motion. The drive is supported by a chamber lid which engages the syringe body and the lid and drive may be detachable from the syringe body and from the mixing element thereby allowing the lid assembly and drive to be reused.

[ We claim:] [1.] A bone cement mixing apparatus comprising:a syringe body, said syringe body defining a generally cylindrical mixing chamber, said mixing chamber having a central axis and first and second oppositely disposed ends, the first of said ends comprising an end wall having an opening therein, said end wall further comprising a slot extending from said opening;a plunger mounted within said mixing chamber so as to be initially disposed adjacent said second end thereof, said plunger being slideably movable along said central axis toward said first end of said mixing chamber;a mixing member rotatably mounted in said mixing chamber, said mixing member including:a rotatable shaft, said rotatable shaft extending through said opening in said end wall and along said central axis; andat least a first blade mounted on and radially extending from said rotatable shaft, rotation of said shaft causing said blade to rotate about said central axis within the interior of said mixing chamber, said blade having a width and thickness which is generally complementary to the length and width of said slot whereby said blade may pass through said end wall slot, residual cement being scraped off said blade by withdrawal thereof through said slot; anddrive means for causing rotation of said mixing member, said drive means including:a handle located to the exterior of said syringe body at said first end of said mixing chamber, said handle being axially movable relative to said mixing chamber, the movement of said handle being parallel to and in-line with said central axis; anda gear mechanism for connecting said handle to said mixing member, said gear mechanism comprising a barley twist mechanism having a threaded rod, a first end of said rod being connected to said handle, said gear mechanism further having a rotatable drive bush, said drive bush being coupled to said mixing member rotatable shaft for rotation therewith, said drive bush being engaged by said threaded rod whereby axial motion of said handle will cause rotation of said drive bush thereby imparting rotational force to said mixing member.
