| Outline of Research at the Start |
The aim of this research is to fulfil bird’s-eye view in MIS by designing a novel surgical endoscopic system. This will allow surgeons to have a broad 3D view alongside the instrument itself, and hence prevent injuries caused by the contact between the instrument’s body and the anatomical area.
|
| Outline of Annual Research Achievements |
The initial prototype had some limitation in modularity and applicability in minimally invasive surgery. Hence, a new modular system has been designed. In particular the system is composed by one or more modules encompassing a camera holder attached to a rigid base.
The rigid base allows the camera to rotate of a specific and predefined angle and can also elongate and shrink bringing the cameras close and far. The cameras utilized for the system are small fish eye of 1.5x1.2x1 cm, hence the overall mechanism is very small and suitable for minimally invasive application.
The system can be easily customized and tailored for different applications that need to create an expanded view. Currently, automation of the rotation of the mechanism and image processing algorithm are under development.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
There were some problem with the initial prototype, hence the design of the system took more time of what was planned. The research has also been delayed due to the outbreak and health issue of the PI.
However, in the last few months there have been significant progress and the model of the mechanism has now been completed. Fabrication and Automatization are also under construction. Additionally, different image processing algorithms have been tested and the applicability of machine learning method is now under study.
|
| Strategy for Future Research Activity |
The mechanism is now under development and the PI contacted external company for the fabrication of the prototypes, as her 3D printers have limitation in the resolutions.
The first prototype will be realized by the end of June and a novel image processing algorithm is under development. A first working system should be ready by the summer. The PI is also planning to submit a reproducible paper on this research to the Robotics and Automation Magazine aiming to have a draft of the manuscript by September. After this step the system will be adopted and tested in narrow space (pipe exploration) and in a realistic minimally invasive surgery scenario.
For the medical setup, anatomical parts of the human body have been fabricated and will be used to realize a phantom mimicking human anatomy.
