Re-inventing bone surgery with CARLO®
Alfredo Emilio Bruno
Advanced Osteotomy Tools AG, Switzerland
A
dvanced Osteotomy Tools AG (AOT) is
reinventing bone surgery with the world's
first, proprietary medical robot, CARLO® (Cold
Ablation Robot-guided Laser Osteotome), that
cuts bone using cold laser ablation mechanism
of action instead of mechanical tools. Although
robotic surgery is in vogue, existing devices are
actually telemanipulators or positioning aids,
where the actual surgical activity continues to
be performed by surgeons using conventional
mechanical cutting instruments that cannot track
the movements of the patient endangering their
safety. Alternatively, CARLO® performs contact
free interventions enabled by laser light so
that, at no time, a mechanical instrument is in
contact with the patient and the incision can be
interrupted instantaneously if necessary. CARLO®
comprises a tactile and certified medical robot,
a laser head with a specially developed bone
cutting laser, a navigation system and the driving
software with a touch-screen based GUI. In this
way, the procedure is 100% digital, from the 3D
planning to the execution of the cut.
Until now it was impossible to use a laser for bone
cutting in surgery, mostly because the lasers and/
or the mechanism-of-action employed resulted in
the narcotization’s of the surrounding bone tissue
precluding healing. AOT succeeded in developing
a miniaturized laser and a proper cooling method
so that the cut surfaces are not exposed to heat
facilitating healing. Besides, the debris particles
are ejected in contraposition with surgeries based
onmechanical cutting tools that are squeezed into
the porous bone structure. Another advantage
is the implementation of functional cutting
geometries, strengthening primary stability in
combination with bio-resorbable implants would
replace screwed solid metal implants in almost
straight cuts. The focused laser beam is always
sharp and sterile and the rendered contacts- and
debris-free cuts displays superhuman precision.
The real-time analysis of the ejected debris
will allow detection of tumor using artificial
intelligence replacing conventional biopsies.
