as best shown in fig1 the apparatus of the present invention is comprises of a pair of syringe bodies 10 and 20 which are held together by a connecting member 30 . associated with each of the syringe bodies 10 and 20 is a piston type plunger 15 and 25 respectively . each of the piston type plungers has a push flange ( 18 and 28 ) which are held together by a connecting clip member 40 so that the two pistonplungers can be actuated simultaneously . the apparatus also includes a separate connector 50 associated with each of the syringe bodies . connectors 50 are used to attach a needle 60 to the syringe body . each of these needles 60 is bent to have a centering section 61 and an elongated section 62 . when the apparatus is assembled , the centering sections of the needles align sections so they run parallel to each other and touch . finally , the apparatus includes a plastic hollow sleeve 70 which receives each of the needles along their elongated sections to hold the needles together in the desired relationship . the syringe bodies 10 and 20 are typically standard off - the - shelf products available through many manufacturers . preferably , the syringe bodies are composed of a hollow tube ( 11 and 21 ) which has a coni ( 12 and 22 ) at one end and a flange ( 13 and 23 ) at the other end . the syringe bodies 10 and 20 can be of the same diameter if it is desirable to dispense the solution from each tube simultaneously at the same rate . likewise , the syringe bodies 10 and 20 can have different predetermined effective diameters to facilitate the simultaneous application of differing predetermined amounts of the two solutions . as stated above , associated with each of the syringe bodies is a piston type plunger . each of the plungers ( 15 and 25 ) has an elongated shaft ( 16 and 26 ), a cylindrical head ( not shown ) which has an ouside diameter slightly less than the inside diameter of the associated syringe body , and a push flange ( 18 and 28 ). the overall length of the plungers 15 and 25 are , preferably , the same . to aid simultaneous actuation of the plungers with equal stroke , the connecting clip member 40 may be secured to each of the push flanges 18 and 28 . clip member 40 has a unique configuration which permits it to be slipped on an off the push flanges 18 and 28 as desired by the surgeon . as a result , the plungers can be actuated simultaneously or separately as desired . clip member 40 is preferably comprised of a solid top member 41 which is rectangular in shape , one or more side members 42 projecting downwardly from at least one , but less than all , of the sides of top member 41 and a base member 43 , which projects from the side member ( s ) 42 and is parallel to the top member 41 . the gap 45 between the base member 43 and the top member 41 is made larger than the thickness of the push flanges 18 and 28 . further , the base member includes two slots 44 for receiving said push flanges . slots 44 are proportioned so they are larger than the diameter of shafts 16 and 26 , but smaller than the diameter of the push flanges 18 and 28 . this configuration permits the push flanges to be clipped within and retained by member 40 so the two plungers are actuated simultaneously . another important feature of the present invention is connecting member 30 . the connecting member 30 , which can be made of a molded plastic , has two open faced semi - cylindrical channels 31 . the channels 31 are formed to receive and retain the syringe bodies 10 and 20 in a parallel alignment . since the channels 31 are open faced , it is also possible to view the amount of material remaining in the syringe bodies 10 and 20 . the holder also includes a unique flange assembly 32 . this flange assembly 32 includes a bottom support 33 which is integrally molded with one end of the semi - cylindrical channels 31 , a plurality of struts 34 , and a top support 35 . these struts 34 separate supports 33 and 35 by a distance larger than the thickness of flanges 13 and 23 of the syringe bodies so that said flanges can be received and retained by supports 33 and 35 and struts 34 . top support 35 includes a pair of flange members 36 and 37 which , because of their unique configuration , provide a means by which the apparatus can be gripped comfortably by a physician in any number of angular orientations . flange members 36 and 37 , combined , project in a plane which is perpendicular to the semicylindrical channels in all directions from said channels . the connecting member 30 , therefore , permits the apparatus to be comfortably held between the fingers in a position which is essentially perpendicular to the fingers at essentially any rotational orientation with respect to the fingers . this is particularly important for the precise and delicate application of the fibrin glue . also of primary significance are the means by which the fibrin glue components are transferred from their respective syringe bodies to the treatment sites . as indicated above , connectors 50 are used to attach needles 60 to the conis 12 and 22 of the syringe bodies . connectors 50 have a central lumin therethrough which is in communication with each interchamber of the syringe body and the lumin of the needle 60 associated with the connector . since there is a separate connector 50 and needle 60 for carrying each material from its syringe body directly to the treatment site , there is no co - mingling of the fibrin glue solutions until they reach the treatment site . as a result , there is no clogging of the dispenser which was an inherent problem with the fibrin glue dispenser of the prior art . also , since the separate needles 60 each have an elongated section which is passed through the hollow sleeve 70 , they form a structure which permits the surgeon to bend the needles simultaneously to form a desired shape . this feature is desirable to enhance visibility when the surgeon is working through a speculum or where direct access is difficult . when in use , one of these syringe bodies is filled with a fibrinogen solution and the other syringe body is filled with a thrombin solution . the adaptors are then attached to the conis of each of the syringe bodies . the needles are , of course , held in parallel alignment by the plastic retaining tube which surrounds them . the apparatus then permits the two solutions to be expelled from the end of the needle simultaneously or separately as desired by actuation of the plungers associated with the syringe bodies .
an improved fibrin glue delivery system is disclosed . the delivery system is comprised of a pair of syringe tubes which can be actuated by plungers simultaneously or independently , a connecting member which holds the syringe tubes in parallel alignment and a unique needle assembly which ensures the components in the syringe bodies will not be comingled until they reach the treatment site . the unique needle assembly also permits the user to manipulate the needles to enhance visibility when the surgeon is working through a speculum or when direct access is difficult .
