Acrobot simulates joint-replacement surgery

A REO product story
Edited by the Engineeringtalk editorial team Mar 18, 2009

REO UK is offering the Acrobot software range, which allows surgeons to simulate joint-replacement operations prior to the real thing.

Acrobot uses computer-assisted 3D planning, surgical navigation and surgeon-controlled robotic surgery.

The Acrobot Modeller software interprets CT scans to reproduce the patient's anatomy in 3D.

The surgeon can use the Acrobot Planner software to plan the exact position and size of implantation.

Acrobot Planner software lets surgeons determine if joint resurfacing can be used rather than the more invasive total hip replacement.

Within Acrobot Planner the surgeon creates a patient plan this is transported to surgical navigation and/or bone sculpting using either Acrobot Navigator or Acrobot Sculptor, depending on the type of joint being replaced.

Navigator and Sculptor use a mechanical tracking system to accurately monitor in real time the position of the patient and the instrumentation.

Mechanical tracking means there are no line-of-sight issues as with optical tracking and no interference issues as with electro-magnetic tracking.

Using the patient plan lets the surgeon see the actual versus planned position of each instrument to achieve accurate bone preparation prior to implant.

Acrobot software delivers benefits to surgeons such as improved accuracy, shorter learning curves and improved bone conservation.

For the patient it reduces discomfort, complications and operation and recovery time.

Acrobot's systems comply with the IEC 60601 (BS EN 60601) standard, which covers electromagnetic compatibility and general safety.

It also incorporates an isolating transformer designed for medical applications.

This helps reduce electric-shock hazards and limits the risk to sensitive monitoring equipment of interference generated on the mains-distribution network.

The isolation transformer is REO's 'REOMED', which meets European standards and conforms to UL 2601 - Medical Equipment Part 1 and CSA 22.2 NO.601.1 Medical Equipment, Part 1 UL File number E304665, for the North and South American markets.
