One-handed (parallel) instrument transfer
Also called: single-handed transfer, parallel transfer
Pick up the used instrument and hand over the next one with the same hand.
In the one-handed transfer, the assistant uses the left hand (for a right-handed operator) to take the used instrument and give the next one, keeping the right hand free for the HVE or air-water syringe. The new instrument is held parallel to the one being used, in the transfer zone below the patient's chin.
How to spot it
- Assistant holds the new instrument between thumb and index finger at the non-working end, resting on the middle finger.
- The new instrument is parallel to the old one during the exchange.
On the tray, in order
- 1. Hold the next instrument near the operator, about 10-12 inches from the operator's hand, ready.
- 2. The operator lifts the used instrument away from the tooth (the signal).
- 3. Grasp the used instrument with the pick-up part of your hand (the little finger) and tuck it toward your palm.
- 4. Place the new instrument firmly into the operator's fingers, working end pointing the way it will be used.
- 5. Roll the used instrument back into holding position if it will be used again, or return it to its place on the tray.
Safety and care
- Never pass sharp instruments over the patient's face.
- Keep working ends pointed away from both of you.
