Carina™ Robotic Assisted Surgery platform development
Our client asked:
Ronovo Surgical © asked Sagentia Innovation to work collaboratively with its internal R&D team to ready its concept for detailed design and take the first iteration of the platform into product development. Carina™ is designed to enable more laparoscopic procedures to be done robotically, and it targets the clinical needs of patients being treated by laparoscopic surgery in China.
The project story:
Our involvement in the programme started with a design review to identify risks and areas for attention. We took the concept to a system architecture suitable for subsequent detailed design, with identification of all key components, usability analysis and industrial design. The work on the overall system included the patient-side cart, surgeon console, set-up and active robotic arms, instrument drive and endoscope drive, as well as wristed instruments. Working alongside the Ronovo Surgical © team, we then detailed the following subsystems and built functional prototypes: instrument arm, instrument drive, monopolar curved scissors with sterile adapter. Most recently we designed a custom-made surgeon input device for the surgeon console, improving range of motion and COGS over the existing solution.
Key challenges included: enabling the maximum range of procedures by optimising set-up and active arm geometries; keeping the arms compact enough to allow easy OR staff interaction; and collaboration across time zones.
