Lastly, hands should be positioned properly relative to the surgical instruments. When holding a microsurgical needle driver, forceps, or scissor, the surgeon's thumb and first two fingers should surround the instrument in a three‐point pencil hold, and the thumb and each digit should touch each other (Figure 3.15). By touching each other, the thumb and digits serve to stabilize one another. The thumb and digits should grasp the instrument about 2–3 cm from the tip of the instrument. This allows enough instrument to protrude from the hold for the instrument to be seen sufficiently in the field of view and provides stability to the end of the instrument, reducing tremor while permitting extension into the small body cavity of a bird, reptile, or fish.
