Abstract:
A device for preparing and injecting a polymeric bone cement under isobaric and isovolumic conditions, said device comprising:a tubular vessel including a first axial end wall having an outlet, a second axial end wall opposite said first axial end wall and having an aperture; a shaft having a first segment engaged into said aperture and including a proximal end section outside said vessel and a distal end section inside said vessel; and a second segment having a proximal section inside said vessel and a distal section passing through and projecting beyond said outlet and having a distal end outside said vessel; an agitator secured to the distal section of said first segment and to the proximal section of said second segment; a piston coaxially and slidingly engaged upon said first segment inside said vessel; and means for selectively locking said piston to said agitator; whereby the volume occupied by the shaft during axial translation within the vessel remains substantially constant.
