A Gesture Recognition Algorithm for Hand-Assisted Laparoscopic Surgery López Casado, Carmen Bauzano-Núñez, Enrique Rivas-Blanco, Irene Pérez-del-Pulgar-Mancebo, Carlos Jesús Muñoz-Martínez, Víctor Fernando Cirugía Robótica Minimally invasive surgery (MIS) techniques are growing in quantity and complexity to cover a wider range of interventions. More specifically, hand-assisted laparoscopic surgery (HALS) involves the use of one surgeon’s hand inside the patient whereas the other one manages a single laparoscopic tool. In this scenario, those surgical procedures performed with an additional tool require the aid of an assistant. Furthermore, in the case of a human–robot assistant pairing a fluid communication is mandatory. This human–machine interaction must combine both explicit orders and implicit information from the surgical gestures. In this context, this paper focuses on the development of a hand gesture recognition system for HALS. The recognition is based on a hidden Markov model (HMM) algorithm with an improved automated training step, which can also learn during the online surgical procedure by means of a reinforcement learning process. 2024-09-26T17:47:18Z 2024-09-26T17:47:18Z 2024-09-26T17:47:18Z 2019 journal article Lopez-Casado M.C.; Bauzano E.; Rivas-Blanco I.; Perez-del- Pulgar C.J.; Muñoz-Martinez V.F.
