In the operation room, surgeons must always be precise when making incisions or performing other surgical tasks. The repetitive tasks are challenging. To assist surgeons, the medical field is using the advancements of AI and collaborative robots in the OR. Surgical robots can control the trajectory, depth, and speed of their movements with great precision. They are especially well-suited for procedures that require the same, repetitive movements as they can work without fatigue. Robots can also remain completely still for as long as needed and can go where traditional tools cannot.

Artificial intelligence is being applied to surgical robotics. AI can determine patterns within surgical procedures to improve best practices and to improve a surgical robots’ control accuracy to submillimeter precision. AI is also being used with machine vision to analyze scans and detect cancerous cases. Laparoscopic video analysis of surgeries, like sleeve gastrectomy procedures, helps to identify missing or unexpected steps in real time. This dissertation focuses on the application of artificial intelligence in the sense of hemorrhage during robotic surgery and proposes a practical method for predicting and handling these circumstances.

My research is focusing on designing the intelligent embedded integrated system to improve the surgeon’s performance in case of unexpected bleeding situations during robotic surgery. This improvement will be done through the following components:

  • Design a mechanism for monitoring the surgery scene and predict the occurrence of bleeding
  • Design preventive system to warn the surgeon about the abrupt movement of surgical tools
  • Detect the pools of blood during the robotic surgery and contour them out
  • Detect the moment of arterial bleeding during the surgery
  • Overcome the complexity of visualization employing Augmented reality incorporated with a 3D model of robotic scene.
