Module 6-Biter, Shaver, Ring Curette, Microfracture Awl

Module 6-Biter, shaver, ring curette, microfracture awl.

For this module you will need to obtain some items from the cafeteria.

One slice of salami or pepperoni

One apple

One styrofoam oatmeal bowl

Use Box # 7 for this lab. On the undersurface of the lid are three screws.

1) trim the bottom out of the styrofoam bowl to make a platform.

2) trim the outline of the meat until it fits within the margins of the styrofoam.

3) center the meat on top of the styrofoam platform and push them onto the three screws until just a few of the threads are showing on the other side.

4) fill the container completely with water and place a 5 gallon bucket under the edge of the table to catch the drainage.

5) Seat the container and place the lid.

6) insert the 30 degree scope into the top left portal with the scope in the L hand and ensure the height of the platform is appropriate; adjust as needed.

7) use the biter to resect a peripheral margin of the meat beginning, contouring to the rim of the styrofoam over the front quarter. Note how the same position of the biter can be held and the debris will float out of the teeth allowing you to march precisely along the rim. Make sure to not gouge the styrofoam.

8) Repeat step 7 with the biter in the L hand and the scope in the right.

9) Use the shaver in the right hand to then smooth out the edge of your resected meat, again making certain to not shave the styrofoam. To do this turn the teeth so that they face the resected margin, initiate the oscillate setting with the foot pedal and gently rotate the teeth up and down as you move along the margin.

10) repeat step 9 with hands switched.

11) Remove the lid and discard the meat and styrofoam. Place the apple over the 3 screws by placing the lid upside down and pushing the apple onto the screw tips.

12) refill the container with water if needed and then re-place the lid.

13) Use the ring curette in the R hand and scrape away a round section of peel and fruit to create a trough with perpendicular walls.

14) Place the microfracture awl into the trough and attempt to create a hole just to the depth of the brass tip without skyving off. This can be done by gentle pressure and twisting motions, or by placing the camera on a holder stand and using gentle taps with the mallet. Attept to place the holes 2 mm apart and perform with both hands.
