In a surgical procedure in India, a robotic scans a affected person’s knee to determine how finest to hold out a joint alternative. In the meantime, in an working room within the Netherlands, one other robotic is performing extremely difficult microsurgery underneath the management of a health care provider utilizing joysticks.
Such situations look set to develop into extra frequent. At current, some guide operations are so troublesome they are often carried out by solely a small variety of surgeons worldwide, whereas others are invasive and rely upon a surgeon’s particular talent.
Superior robotics are offering instruments which have the potential to allow extra surgeons to hold out such operations and achieve this with a better price of success.
‘We’re coming into the following revolution in drugs,’ stated Sophie Cahen, chief government officer and co-founder of Ganymed Robotics in Paris.
New knees
Cahen leads the EU-funded Ganymed mission, which is growing a compact robotic to make joint-replacement operations extra exact, much less invasive and – by extension – safer.
The preliminary focus is on a sort of surgical procedure referred to as complete knee arthroplasty (TKA), although Ganymed is seeking to increase to different joints together with the shoulder, ankle and hip.
Ageing populations and way of life adjustments are accelerating demand for such surgical procedure, based on Cahen. Curiosity in Ganymed’s robotic has been expressed in lots of quarters, together with distributors in rising economies akin to India.
‘Demand is super-high as a result of arthroplasty is pushed by the age and weight of sufferers, which is rising all around the world,’ Cahen stated.
Arm with eyes
Ganymed’s robotic will intention to carry out two important capabilities: contactless localisation of bones and collaboration with surgeons to help joint-replacement procedures.
It contains an arm mounted with ‘eyes’, which use superior computer-vision-driven intelligence to look at the precise place and orientation of a affected person’s anatomical construction. This avoids the necessity to insert invasive rods and optical trackers into the physique.
“We’re coming into the following revolution in drugs.”
– Sophie Cahen, Ganymed
Surgeons can then carry out operations utilizing instruments akin to sagittal saws – used for orthopaedic procedures – in collaboration with the robotic arm.
The ‘eyes’ help precision by offering so-called haptic suggestions, which prevents the motion of devices past predefined digital boundaries. The robotic additionally collects knowledge that it could course of in actual time and use to hone procedures additional.
Ganymed has already carried out a medical examine on 100 sufferers of the bone-localisation know-how and Cahen stated it achieved the specified precision.
‘We had been extraordinarily happy with the outcomes – they exceeded our expectations,’ she stated.
Now the agency is performing research on the TKA process, with hopes that the robotic can be totally out there commercially by the top of 2025 and develop into a mainstream device used globally.
‘We need to make it inexpensive and accessible, in order to democratise entry to high quality care and surgical procedure,’ stated Cahen.
Microscopic issues
Robots are being explored not just for orthopaedics but in addition for extremely advanced surgical procedure on the microscopic degree.
The EU-funded MEETMUSA mission has been additional growing what it describes because the world’s first surgical robotic for microsurgery licensed underneath the EU’s ‘CE’ regulatory regime.
Known as MUSA, the small, light-weight robotic is connected to a platform geared up with arms capable of maintain and manipulate microsurgical devices with a excessive diploma of precision. The platform is suspended above the affected person throughout an operation and is managed by the surgeon by specifically tailored joysticks.
In a 2020 examine, surgeons reported utilizing MUSA to deal with breast-cancer-related lymphedema – a continual situation that generally happens as a aspect impact of most cancers remedy and is characterised by a swelling of physique tissues because of a build-up of fluids.

To hold out the surgical procedure, the robotic efficiently sutured – or linked – tiny lymph vessels measuring 0.3 to 0.8 millimetre in diameter to close by veins within the affected space.
‘Lymphatic vessels are under 1 mm in diameter, so it requires a whole lot of talent to do that,’ stated Tom Konert, who leads MEETMUSA and is a medical subject specialist at robot-assisted medical know-how firm Microsure in Eindhoven, the Netherlands. ‘However with robots, you’ll be able to extra simply do it. To date, with regard to the medical outcomes, we see very nice outcomes.’
Regular arms
When such delicate operations are performed manually, they’re affected by slight shaking within the arms, even with extremely expert surgeons, based on Konert. With the robotic, this drawback might be prevented.
MUSA also can considerably scale down the surgeon’s normal hand actions relatively than merely repeating them one-to-one, permitting for even better accuracy than with standard surgical procedure.
‘When a sign is created with the joystick, we’ve got an algorithm that can filter out the tremor,’ stated Konert. ‘It downscales the motion as effectively. This may be by a factor-10 or 20 distinction and provides the surgeon a whole lot of precision.’
Along with treating lymphedema, the present model of MUSA – the second, after a earlier prototype – has been used for different procedures together with nerve restore and soft-tissue reconstruction of the decrease leg.
Subsequent technology
Microsure is now growing a 3rd model of the robotic, MUSA-3, which Konert expects to develop into the primary one out there on a widespread business foundation.

This new model may have varied upgrades, akin to higher sensors to boost precision and improved manoeuvrability of the robotic’s arms. It’ll even be mounted on a cart with wheels relatively than a set desk to allow straightforward transport inside and between working theatres.
Moreover, the robots can be used with exoscopes – a novel high-definition digital digital camera system. This may enable the surgeon to view a three-dimensional display by goggles to be able to carry out ‘heads-up microsurgery’ relatively than the less-comfortable strategy of trying by a microscope.
Konert is assured that MUSA-3 can be extensively used throughout Europe and the US earlier than a 2029 goal date.
‘We’re at present finalising product improvement and getting ready for medical trials of MUSA-3,’ he stated. ‘These research will begin in 2024, with approvals and begin of commercialisation scheduled for 2025 to 2026.’
MEETMUSA can also be trying into the potential of synthetic intelligence (AI) to additional improve robots. Nevertheless, Konert believes that the intention of AI options could also be to information surgeons in direction of their targets and help them in excelling relatively than attaining fully autonomous surgical procedure.
‘I feel the surgeon will at all times be there within the suggestions loop, however these instruments will certainly assist the surgeon carry out on the highest degree sooner or later,’ he stated.
