Title
(EN) BONE CEMENT MIXER AND METHOD
(FR) MELANGEUR DE CIMENT D'OS ET PROCEDE CORRESPONDANT
Abstract
(EN)
A bone cement mixer (10) having a cartridge housing (12) for receiving an open bone cement cartridge (120) filled with bone cement powder (164) with a stirrer (142) in the cartridge, and a cover (14) which is fitted over the housing (12) to define a vacuum chamber (20). The chamber is evacuated and monomer liquid (188) is flowed into the bone cement powder in the cartridge in a stream (162) that penetrates the bone cement powder and distributes monomer liquid essentially uniformly along the height of the bone cement powder. The powder and liquid are then mechanically mixed to form bone cement.
(FR)
La présente invention concerne un mélangeur de ciment d'os (10) comportant, d'une part un logement à cartouche (12) destiné à accueillir une cartouche ouverte (120) de ciment d'os remplie de poudre de ciment d'os (164) avec présence d'un agitateur (142) dans la cartouche, et d'autre part un couvercle (14) qui s'adapte sur le logement (12) de façon à définir une chambre à dépression (20). Une fois que le vide est réalisé dans la chambre, un liquide monomère (188) est introduit dans la poudre de ciment d'os contenue dans la cartouche sous forme d'un courant (162) qui pénètre dans la poudre de ciment d'os et qui répartit le liquide monomère sensiblement de façon uniforme le long de la hauteur de la poudre de ciment d'os. La poudre et le liquide sont alors mélangés mécaniquement de façon à former le ciment d'os.
