Kit for preparing a bone filler mixture, a cartridge specially adapted to said kit, and an implantation set including said kit

Abstract

The invention relates to a kit for preparing a mixture of a natural or synthetic bone filler material with blood or physiological serum. According to the invention, the kit comprises a stand, a cup, and a tube for containing the mixture, the tube being open at both ends, the stand having receiver means for receiving one end of the tube in a vertical position, and the cup including an orifice in its center and communicating with a sleeve for releasable assembly on the other end of the tube.

1 . A kit for preparing a mixture of a natural or synthetic bone filler material with blood or serum, the kit comprising a stand, a cup, and a tube for containing the mixture and open at both ends, the stand including receiver means for receiving one end of the tube in a vertical position, and the cup including in its center an orifice which communicates with a sleeve for releasable assembly on the other end of the tube.  
   
   
       2 . A kit according to  claim 1 , wherein said receiver means of the stand is provided with releasable assembly means adapted to co-operate with complementary assembly means provided on the tube.  
   
   
       3 . A kit according to  claim 2 , wherein said complementary assembly means provided on the tube are adapted to co-operate with the releasable assembly means of a cylindrical duct of an injection syringe.  
   
   
       4 . A kit according to  claim 2 , wherein said tube is a trephine provided with teeth around the periphery of its front opening and adapted to be releasably assembled by said complementary assembly means to the end of a mandrel of a bone recovery drill device for driving it in rotation.  
   
   
       5 . A kit according to  claim 1 , wherein said receiver means of the stand includes a sealing ring for establishing a leaktight junction at the opening of the tube between the tube and said receiver means.  
   
   
       6 . A kit according to  claim 1 , wherein the stand includes receiver means for receiving the sleeve of the cup, distinct from said receiver means for receiving the end of the tube, and adapted to close said orifice.  
   
   
       7 . A kit according to  claim 6 , wherein said receiver means for receiving the sleeve of the cup is a generally cylindrical peg of diameter slightly smaller than the inside diameter of said sleeve.  
   
   
       8 . A kit according to  claim 1 , wherein said receiver means for receiving the tube is a generally cylindrical peg of diameter slightly smaller than the inside diameter of the tube.  
   
   
       9 . A kit according to  claim 2 , wherein said assembly means are pin means.  
   
   
       10 . A kit according to  claim 2 , wherein said assembly means are bayonet means.  
   
   
       11 . A kit according to  claim 2 , wherein said assembly means are snap-fastener means.  
   
   
       12 . A kit according to  claim 2 , wherein said assembly means are screw-fastener means.  
   
   
       13 . A cartridge of mixable bone filler material, the cartridge comprising a tubular shell arranged in such a manner as to form said tube of the kit according to  claim 1 .  
   
   
       14 . An implantation set comprising a box containing at least one bone-taking trephine, at least one injection syringe with an injection duct having assembly means at its distal end for releasably assembling with said trephine, and a kit according to  claim 1 .  
   
   
       15 . An implantation set according to  claim 14 , in which the height of the box when closed by a lid is substantially equal to the height of the stand with the cup engaged on the receiver means of the stand of said kit so that said box, when closed, is suitable for containing said stand positioned flat on the bottom of the box and carrying said cup on its receiver means.
