Surgical Navigators helps orientation in the anatomy enabling:
additional virtual viewing of the patient (a virtual and “clean” map)
the view of the surgical instruments in relationship with the virtual map of the anatomy
the inspection of the surgical field from various viewpoints
additional information in the navigator monitor to guide some steps of interventions
Surgical Navigators

Assistive functionalities
This working modality is intended to allows to load the planning of the intervention so that the system can indicate to the surgeon some of the steps planned to perform the intervention
Access Port guided positioning
The software loads an oriented sphere to mark the position on the abdomen loading a file saved in the simulation phase.

Active functionalities
The thread monitors if any robot joints are too close to the indicated anatomical structures structures and in case of collision returns a visual and acoustic alarm to alert the surgeon
The surgeon during the loading phase of the anaotmy can choose some “non‐touchable” anatomical structure that the sofwtare enrole in a collision detecition thread.
The system actively contributes to the execution of the surgical procedure

Conclusions
The Computer Guidance Module showed good results in term of usability and
performance (latency, 3D environment visual quality and frame rate), whereas
the registration accuracy is acceptable (for a phantom test).
It enables the surgeon to easily navigate into the patient anatomy relying on
the virtual view offered by the system.
It offers the surgeon also assistive functionalities to facilitate the port
placement
It offers active functionalities to preserve the safety of delicate organs during
the intervention
