Patent ID: 8118779

Claim:
A collagen delivery syringe gun, comprising a frame; a handle extending from the frame; a barrel extending from the frame nearly perpendicular to the handle, the barrel having an open syringe chamber with a proximal end and a distal end, the barrel remains open for installation, use and removal of syringes; a syringe support tip attached to the distal end of the open syringe chamber of the barrel wherein the syringe support tip is configured to receive a syringe having a needle, a syringe plunger and a collagen material therein; and a threaded plunger extending through the frame and into the barrel, wherein the threaded plunger is rotatable to engage the syringe plunger and expel the collagen material from the syringe through its needle; a half nut within the frame, wherein the half nut is threaded and wherein the half nut threadably engages the threaded plunger; a trigger extending from the frame, wherein the trigger is movable between an extended position in which the trigger keeps the half nut engaged with the threaded plunger, and a depressed position in which the trigger allows the half nut to disengage from the threaded plunger; wherein the threaded plunger slides freely within the frame and barrel when the half nut disengages the threaded plunger, and the threaded plunger moves linearly within the frame and barrel as the threaded plunger rotates with respect to the half nut; and wherein, optionally, the threaded plunger further comprises a rotatable handle which a user can rotate to rotate the threaded plunger and move the threaded plunger within the frame and the barrel independently of the trigger.
