9. MulTipeg
The MulTipeg is made from titanium and has an integrated grip for the MulTipeg Driver on top. Inspect the MulTipeg for damage before use. Damaged MulTipegs
should not be used due to the risk of erroneous measurements.
There are different MulTipegs available made to fit different implant systems and types. Please refer to the updated list from the supplier.
Measurementsshould only beperformed using thecorrect MulTipegs. Using thewrong MulTipeg couldcause
erroneous measurements or damages to the MulTipeg or implant.
Theinstrument emits short magnetic pulses with pulse duration of 1 ms and strength of +/- 20 gauss, 10 mm
from the instrument tip. Precautions might be necessary when using the instrument close to cardiac
pacemakers or other equipment sensitive to magnetic fields.
10. Technical function
For bringing the MulTipeg into vibration, short magnetic pulses aresent from theinstrumenttip. The magnetic pulses interact with the magnet insidethe MulTipeg
and causethe MulTipeg to vibrate. A pickup in the instrument picks up the alternating magnetic field from the vibrating magnet, calculate thefrequency and from
that, the ISQvalue.
11. Implant stability
An implant can have different stabilities in different directions. Make sure to measure from different directions around the top of the MulTipeg.
12. ISQ-value
The stability of the implant is presented as an "ISQ value". The higher the value, the more stable theimplant. The ISQ is described in numerous clinical studies. A
list of studies can be ordered from the supplier.
13. Batteries & charging
Theinstrument contains 2 NiMH battery cells that must becharged before use. A full chargetakes approximately 3 hours. From fully charged, theinstrument can
measure continuously for 60 minutes before it needs to be recharged. The yellow LED is lit when the battery needs recharging. The yellow LED flashes when the
battery reaches a critical level. When the battery reaches a critical level, theinstrument shuts off automatically. When thebatteries arecharging, the blue LED is lit.
When the batteries arefully charged, the light goes off. Thecharger should not be plugged in while measuring due to the risk of power line interference making it
difficult to measure.
14. Usage
14.1 Instrument on/off
To turn the instrument on, press the operating key. A short beep should be heard and then all display segments are lit up for a short while. Check that all display
segments are lit.
If any error code (EX, where "X" is the error number) is shown during start up, please refer to the section "Troubleshooting".
To turn off, press the operating key. The instrument will power down automatically after 30 seconds of inactivity.
14.2 Measurement
A MulTipeg (fig 3) is mounted onto the implant by using the MulTipeg driver (fig 2). Use hand-tightening with 6-8 Ncm of tightening torque. Turn on the instrument
and hold the tip close to the top of the pin (fig 5). When a signal is received, a beep is heard and then the ISQ-value is shown on the display for a short while before
the instrument starts to measureagain.
If electromagnetic noise is present, theinstrument cannot measure. The electromagnetic noise warning is audible as well as visible on the display. Try to remove the
source of the noise. The source could beany electric equipment close to theinstrument. When an ISQ valueis displayed, it is simultaneously sent via Bluetooth to the
paired instrument if a Bluetoot connection has been made (as specifie in section 14.3.1).
14.3 ISQ Bluetooth transfer
Connection to other equipment can result in unidentified risks to patients, operators or others. Identification, analysis, evaluation and control of these risks are the
responsibilities of the user. Changes to this or the paired device can introduce new risks that require additional analysis.
14.3.1 Bluetooth pairing
To establish Bluetooth data transfer, theinstrument has to be paired with a pairableinstrument. The pairing only needs to be done once.
See section 19 for a listing of pairable instruments.
To pair, turn on the instrument and press and hold the key for at least 3 seconds until the instrument enters pairing mode, "PA" is shown on the display and the
beeper sounds while pairing. To abort pairing attempts, press thekey again. When pairing is completed, a beep is heard and measurements starts. After 2 minutes
of pairing attempts without succesful pairing, the instrument will return to measurement mode.
14.3.2 Sending ISQ value
If the Osseo 100+ is paired, the displayed ISQ and battery status is automatically sent to the paired device.
15. Cleaning and maintenance
Before use, the parts should be cleaned and disinfected.
15.1 Recommended disinfectants
The following disinfectants are recommended for the instrument, the MulTipeg and the MulTipeg Driver:
•
Schülke & Mayr: Mikrozid AFLiquid
•
Dürr: FD 322
•
Metrex: CaviCide
Follow the instructions for use for the disinfectant that is used.
Do not autoclave the instrument
