Claims (20)

  1. 1. A dispensing gun (1) for a cartridge, comprising a frame (2) with a handle (21), an injection stopper (22) for attaching a cartridge, preferably a cartridge having a base portion with at least two opposite locking wings, wherein the injection stopper (22) is located in the distal portion of the frame (2), a lever (3) with at least two teeth (31) and a piston (4) with at least two recesses (41), wherein:
  2. - the dispensing gun (1) contains means for directly fixing the cartridge on the injection valve (22); and
  3. - the dispensing gun (1) comprises means for moving the piston of the gun into the cartridge in such a way that the material contained in the cartridge is extruded in one stroke of the piston; and
  4. - the dispensing gun (1) is configured in such a way that the lever (3) is in a state in which the first recess (41) of the piston (4) and the first tooth (31) of the lever (3) engage before attaching the cartridge, so that the lever (3) and the handle (21) form an angle in the range from 80° to 120°, preferably 90°.
  5. 2. The dispensing gun according to claim 1, characterized in that the lever (3) also has a final position in which the lever (3) is pressed and the piston (4) of the dispensing gun is engaged with the cartridge, thus ensuring complete extrusion of the material initially contained in the cartridge.
  6. 3. The dispensing gun according to claims 1 and 2, configured in such a way that the lever (3) further includes an intermediate state in which the lever (3) is maintained in a position between the actuation state and the final state for contact of the piston (4) with the piston of the cartridge so that the dispensing gun is ready for use for extruding the material contained in the cartridge.
  7. 4. A dispensing gun according to any one of claims 1-3, wherein the injection stopper (22) is configured to lock a cartridge having a base portion with two opposing locking wings, preferably the injection stopper (22) includes means for directly locking the outer sleeve (7) of the cartridge (6) by means of its two locking wings (77).
  8. 5. A dispensing gun according to any one of claims 1-4, wherein the piston (4) is a rod configured to be received into the internal volume of the cartridge when fixed on the distal part of the injection valve (22).
  9. 6. A dispensing gun according to any one of paragraphs 1-5, characterized in that turning the lever (3) from the actuated state to the final state moves the piston (4) in the range from 10 mm to 20 mm, preferably from 14 mm to 16 mm, more preferably from 15 mm to 18 mm.
  10. 7. A dispensing gun according to any one of paragraphs 1-6, characterized in that, when the lever (3) is in the actuated state, the distal end of the internal piston (4) is located on the proximal end of the injection valve (22).
  11. 8. A dispensing gun according to any one of paragraphs 1-7, characterized in that the frame (2) includes one or more ribs, preferably one rib.
  12. 9. The dispensing gun according to paragraph 8, characterized in that the dispensing gun includes a washer located behind the edge of the frame.
  13. 10. A dispensing gun according to any one of paragraphs 3-9, characterized in that when the lever (3) is in an intermediate state, the lever (3) is maintained in a position between the actuation state and the final state by a spring-loaded plunger.
  14. 11. The dispensing gun according to claim 4, wherein the injection shutter (22) includes a proximal part configured to connect with the distal end of the frame (2), and a distal part configured to connect and lock two opposite locking wings of the base part of the cartridge.
  15. 12. A dispensing gun according to any one of paragraphs 1-11, wherein the frame (2) is made of a polymer obtained by injection molding, and the injection valve (22) is made of metal.
  16. 13. A dispensing gun according to any one of paragraphs 1-12, characterized in that the dispensing gun is capable of withstanding autoclave processing and/or is deactivatable.
  17. 14. A system comprising a dispensing gun (1) according to any one of paragraphs 1-13 and a cartridge (6) having a base part with two opposite locking wings (77).
  18. 15. A method for dispensing material by a system according to claim 14, comprising a cartridge (6) having a base portion with at least two opposite locking wings (77), and a dispensing gun (1) according to any one of claims 1-13, in which the injection valve (22) includes a distal plate (221) with an opening (222), the shape of which corresponds to the shape of the base portion of the cartridge (6), characterized in that:
  19. - at the first stage of actuating the dispensing gun (1), under the action of the traction force applied to the lever (3), the lever is set in the actuation state, in which the first recess (41) of the piston (4) and the first tooth (31) of the lever (3) before attaching the cartridge (6) engage, so that the lever (3) and the handle (21) form an angle from 80° to 120°, preferably almost 90°, and so that the piston (4) inside the frame (2) is at a non-zero distance e x from the distal end of the injection valve (22);
  20. - at the second stage of fixation on the distal part of the injection valve (22) of the base part of the cartridge containing the material that needs to be extruded;
