Abstract

Background

Compared with traditional open surgery, robotic-assisted minimally invasive surgery lacks force sensing ability.

Methods

A sensorless transparency optimised force safety mechanism is put forward to improve the external force safety of the surgical robot in this paper. An improved fixed-time indirect adaptive fuzzy controller is proposed to approximate the unknown uncertainties in the dynamics of the patient-side manipulator. An online force simulation controller is designed based on the hierarchical force.

Results

Simulations and experiments demonstrate that the designed fixed-time indirect adaptive fuzzy controller exhibits excellent performance in trajectory tracking, fixed-time convergence, fuzzy approximation, and smooth control input. In addition, the online force simulation controller effectively decreases the force in the potentially unsafe area, thereby inhibiting the unsafe force.

Conclusions

This mechanism offers potential applications to improve the safety of external forces for the sensorless surgical robots.

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
