Abstract

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. The manual mixer includes a mixing assembly and an actuation assembly for actuating the mixing assembly. The mixing assembly includes at least a paddle portion and a plunger portion. The plunger portion is simultaneously capable of rotational movement with the paddle portion and movement upwardly or downwardly along the paddle portion. Rotation of the paddle portion serves to facilitate mixing and agitating of the materials, and downward movement of the plunger portion serves to facilitate dispensing of the materials from the manual mixer.

First claim

We claim:

1. A method of mixing and agitating materials using a manual mixer, the method comprising:
providing the manual mixer having a body portion, a mixing assembly, and an actuation assembly, the body portion defining an interior cavity for receiving at least a portion of the mixing assembly, the mixing assembly including a paddle portion and a plunger portion, a portion of the paddle portion being received within an aperture extending through the plunger portion, the plunger portion being moveable downwardly along the paddle portion, and the actuation assembly being operatively interconnected with the mixing assembly;
removing the mixing assembly from the interior cavity;
providing the materials to be mixed and agitated in the interior cavity;
replacing the mixing assembly in the interior cavity; and
actuating the actuation assembly to rotate the paddle portion and the plunger portion, and simultaneously move the plunger portion downwardly along the paddle portion within the interior cavity, and to mix and agitate the materials provided in the interior cavity via the rotation of the paddle portion and the plunger portion, and via the downward movement of the plunger portion.

2. The method of claim 1 , further comprising, before the actuation of the actuation assembly, holding the plunger portion in an upward position using a clamp portion received through the body portion, and removing the clamp portion to allow movement of the plunger portion during the act.

3. The method of claim 1 , further comprising expelling the materials from the interior cavity through a valve assembly via downward movement of the plunger portion in the interior cavity.

4. The method of claim 1 , further comprising, during the actuation of the actuation assembly, passing a portion of the materials from a first side of the paddle portion to a second side of the paddle portion through at least one opening in the paddle portion.

5. The method of claim 4 , wherein the first side and the second side of the paddle portion are substantially planar and substantially parallel to one another.

6. The method of claim 1 , wherein the body portion includes an interior surface defining at least a portion of the interior cavity, the interior surface including a first set of threads, and the plunger portion including a second set of threads, and further comprising, during the actuation of the actuation assembly, engaging the first set of threads and the second set of threads to one another, and moving the plunger portion downwardly from a first position to a second position via the rotation of the plunger portion and rotational interaction of the first set of threads and the second set of threads.

7. The method of claim 1 , wherein the actuation assembly includes a transmission and a drive shaft, the transmission including a first gear connected to the paddle portion and a second gear connected to the drive shaft, and further comprising, during the actuation of the actuation assembly, operatively connecting the second gear to the first gear via linear movement of the drive shaft from a first position to a second position.

8. The method of claim 7 , further comprising, during the actuation of the actuation assembly, translating the linear movement of the drive shaft from the first position to the second position thereof into rotation the second gear to correspondingly rotation the paddle portion when the first gear and the second gear are operatively connected to one another.

9. The method of claim 8 , wherein the drive shaft includes a helical portion, and the second gear includes a wall portion and an aperture provided in the wall portion, the aperture being configured to receive the drive shaft therein, interaction between the drive shaft and the aperture due to the linear movement of the drive shaft therethrough causing rotation of the second gear.

10. The method of claim 8 , wherein the actuation assembly includes a button portion operatively interconnected with the drive shaft, and further comprising, during the actuation of the actuation assembly, depressing the button portion to facilitate the linear movement of the drive shaft from the first position to the second position thereof.

11. A method of mixing and agitating materials using a manual mixer, the method comprising:
providing the manual mixer having a body portion, a mixing assembly, and an actuation assembly, the body portion defining an interior cavity for receiving at least a portion of the mixing assembly, the mixing assembly including a paddle portion and a plunger portion, a portion of the paddle portion being received within an aperture extending through the plunger portion, the plunger portion being moveable downwardly along the paddle portion, and the actuation assembly including a transmission and a drive shaft, the transmission including a first gear connected to the paddle portion and a second gear connected to the drive shaft;
providing the materials to be mixed and agitated in the interior cavity; and
actuating the actuation assembly to operatively connect the second gear to the first gear via linear movement of the drive shaft from a first position to a second position, to translate the linear movement of the drive shaft from the first position to the second position thereof into rotation the second gear to correspondingly rotate the paddle portion when the first gear and the second gear are operatively connected to one another, to rotate the plunger portion with the rotation of paddle portion, and simultaneously move the plunger portion downwardly along the paddle portion within the interior cavity.

12. The method of claim 11 , further comprising mixing and agitating the materials provided in the interior cavity via the rotation of the paddle portion and the plunger portion, and via the downward movement of the plunger portion.

13. The method of claim 12 , further comprising, during the mixing and agitation of the materials, passing a portion of the materials from a first side of the paddle portion to a second side of the paddle portion through at least one opening in the paddle portion.

14. The method of claim 13 , wherein the first side and the second side of the paddle portion are substantially planar and substantially parallel to one another.

15. The method of claim 11 , further comprising, before the actuation of the actuation assembly, holding the plunger portion in an upward position using a clamp portion received through the body portion, and removing the clamp portion to allow movement of the plunger portion during the act.

16. The method of claim 11 , further comprising expelling the materials from the interior cavity through a valve assembly via downward movement of the plunger portion in the interior cavity.

17. The method of claim 11 , wherein the body portion includes an interior surface defining at least a portion of the interior cavity, the interior surface including a first set of threads, and the plunger portion including a second set of threads, and further comprising, during the actuation of the actuation assembly, engaging the first set of threads and the second set of threads to one another, and moving the plunger portion downwardly from a first position to a second position via the rotation of the plunger portion and rotational interaction of the first set of threads and the second set of threads.

18. The method of claim 11 , wherein the drive shaft includes a helical portion, and the second gear includes a wall portion and an aperture provided in the wall portion, the aperture being configured to rece
