 Date de prise de poste : 1 janvier 2024


Surgical robotic Deep Learning Workflow recognition.



Under a collaboration with a major company developing surgical robots and the obstetrical surgery department of Rennes University Hospital, we have access to a large and rare dataset composed of more than 80 hysterectomies. This dataset is composed of surgical video, robotic arms kinematics automatically recorded, and the surgical workflow description recorded manually which is time-consuming [1]. To include new surgeries, it is necessary to develop an automatic workflow recognition method. For this, convolutional neural networks, recurrent neural networks, or transformers [2] could be used.


The objective of the development of such method is to increase the database in order to study surgical workflows specific to patient’s anatomical characteristics, surgical team’s habits or preferences. In previous studies, we have demonstrated the existence of such preferences on the procedural and kinematic aspects. We have highlighted sequence of activities [3] or kinematic performances [4] specific to the level of experience and also specific to each surgeon individually [5].


Objective of the internship

The objective of this work is to develop automatic workflow recognition deep-learning methods based on video and/or kinematic data. To achieve this goal, the internship will be divided into 3 steps:

  • Study the state of the art on automatic workflow recognition;
  • Develop automatic workflow recognition deep-learning methods-based video and/or kinematic data;
  • Compare the performances between methods on surgical available data.


Profile researched

The candidate must have knowledge in deep learning, data analysis, computer science and programming (python).
