Oscar Pro™

OSCAR PRO™ is an ultrasonically powered surgical system intended to reduce the challenges associated with revision arthroplasty surgery.
The system consists of:
  • A mains-powered, portable generator and control unit with a large touch screen display.
  • A universal handset connected via a cable encased in silicone rubber to the generator, integrated peristaltic water pump and footswitches.
  • A range of single-use probes for cement removal, cementless prosthesis removal and for select osteotomies.

History

Evolution of the OSCAR system

The first generation of OSCAR (OSCAR 1) was launched in 1990 in the UK followed by the USA in 1997.

Steady development the OSCAR saw 2nd and 3rd generations brought to market in 2002 and 2010 respectively.

Today, in the 2021, we’re moving ahead with the 4th generation.

OSCAR PRO™

Orthofix and the OSCAR system

Orthofix has been involved with the OSCAR product line since 1993, when it acquired the original company – Orthosonics - and this revolutionary technology.

Orthofix is the proud manufacturer of OSCAR and includes it into its diversified portfolio focused on improving patients' lives by providing superior reconstruction and regenerative musculoskeletal solutions to physicians worldwide.

The OSCAR portfolio is now widely distributed via Orthofix sales representatives, distributors and subsidiaries.

Frequently Asked Questions

OSCAR™

Probe Stuck in Cement

This is most likely to occur when a piercer is being used. If the tip of the piercer is pushed too deeply into the cement and allowed to remain in situ, then the cement behind the tip is liable to solidify and trap the probe. If this happens, the load on the probe may be excessive preventing normal resonance because of the mass of cement now attached to the probe. If this occurs the generator will automatically enter a ‘stuck in cement’ mode and display CEMENT RELEASE MODE Energise the handset, but do not apply any pressure on the handset for the first 2 seconds of use ( this gives the channel a better chance to find a resonant feature ). The generator will perform repeated scans of the handset, sounding a double beep as it does so. Whilst this occurs, gently remove the probe from the cement. When free from cement the channel mode will return to normal operation. If the display shows WAIT - REDUCE PRESSURE just wait for 4 seconds and the module will reset automatically. Again, energise handset but apply little pressure on the handset for the first two seconds of use, then slowly remove probe.

This procedure may lead to an OVER-TEMPERATURE message on the LCD. Allow the channel to cool for several minutes. When the channel resets attempt removal again. This process may take a couple of attempts, depending how deep the probe is stuck in the cement.

Metal Fatigue

This can occur if the probe comes into contact with metal and becomes scratched, causing a stress riser to appear. When this happens, fragments of the probe are at risk of coming off during operation.

Solution: Change the probe and replace at the earliest opportunity.

Intermittent Power During Operation

If the handset/probe suffers from intermittent power and a clicking noise, caused by the tripping of relays, coming from the generator, then the cable connecting the handset to the generator will have fractured.

Solution: Change the cable associated with the defective system.

Low Power During Operation

i. The probe will appear to be working inefficiently if it is pressed too hard into the cement. The generator will alert the surgeon by sounding an alarm.

Solution: Ease of pressure to enable the probe to work at maximum efficiency always press the tip gently into the cement and use gentle force:- allow the ultrasound to do the work. Avoid excessive force at all times.

ii. Lack of power during cutting can be due to the interface between the probe and the handset being slack.

Solution: Tighten the connection using the 9mm spanner provided. The power level can also be diminished if this interface is not clean and has been damaged due to the presence of particles. Should this occur, it is necessary to re surface the interface, which can be done by Orthofix Srl.
Should the stud attached to the probe become loose, it must be returned to Orthofix Srl for repair.

iii. Loss of power when cutting cement can also be due to the crystals in the handset overheating. The crystals will heat up naturally during normal use, but if excessive force is used for prolonged periods of time this heating will affect performance. As the handset warms up its resonant frequency will drop. If the handset becomes too warm the frequency will drop out of the handsets’ working range and the channel will shut down. The LCD will display FREQUENCY TOO LOW

Solution: Use another handset and allow the hot handset to cool down. The channel will reset automatically when the handset is cool.

Probe Stuck in Cement

This is most likely to occur when a Piercer is being used. If the tip of the Piercer is pushed too deeply into the cement and allowed to remain in situ, then the cement behind the tip is liable to solidify and trap the probe. If this happens, the load on the probe may be excessive, preventing normal resonance because of the mass of cement now attached to the probe. An error message will appear on the generator screen warning the user about probe in ‘stuck in cement’ mode. In order to remove the probe from cement, energize the handset but do not apply any pressure to the handset for the first 2 seconds of use (this gives the channel a better chance to find a resonant feature). The generator will perform repeated scans of the handset, sounding a double beep as it does so. Whilst this occurs, gently remove the probe from the cement. When free from cement the channel mode will return to normal operation. This procedure may lead to an OVER-TEMPERATURE message on the screen. Allow the channel to cool for several minutes or switch channels. When the channel resets, attempt removal again. This process may take a couple of attempts, depending how deep the probe is stuck in the cement.
