TORS System

Torsional Orthopaedic Revision System

The newest ultrasound technology to remove bone cement

The TORS system is currently the world's newest and most modern surgical ultrasound device for the removal of polymethyl methacrylate (PMMA) bone cement.

The system also contains an HF surgery module / device for high-frequency, tissue cutting and coagulation of vessels.

The technically mature system impresses with its extremely stable functional performance compared to the systems available on the market, as well as simple and pleasant handling.

Advantages at a glance:

• Can be used with all cemented endoprostheses
• Faster softening of the bone cement thanks to the vertical and torsional movement of the newly designed probes compared to conventional systems
• Targeted and efficient removal of the bone cement using piercer and scraper probes in various sizes
• Acoustic feedback for cortical contact
• Precise medullary canal preparation for the stem revision
• Relief of the operating hand thanks to the foot switch to activate the probes
• Improved planning of the surgical procedure and significantly reduced operating time
• Easy setup and handling of the system
• Soft tissue transducer, integrated HF device with 2 energy levels for cutting and coagulating

The new Longitudinal-torsional Piercer Probes enable the most efficient means for impact-free cement removal.

The Longitudinal-torsional combination-mode ultrasound offers the best of both technology worlds with newly patented acoustic designs to maximise energy delivery efficiency and therefore ease of cement removal, reducing time and stress.

The impedance mismatch between titanium and bone means that TORS stops cutting and squeals on bone contact in the same way as longitudinal ultrasound systems.

The piercer has a round, lance-shaped tip with holes on the head. It is used for the forward and backward processing of the bone cement as well as the perforation of the distal cement peg.

The aim is to first loosen the bone cement in depth and then to transport parts of it from the depth towards the opening.
These probes can be extended using the T1ESR1, T1ECR1 or T1ESR2 extensions.

The scraper has a round, flattened tip. It is used to remove the bone cement.
The aim is to first loosen the bone cement in depth and then to transport parts of it from the depth towards the opening.

These probes can be extended using the T1ESR1, T1ECR1 or T1ESR2 extensions.
