Filiform Variable Stiffness Technologies for Medical Robotics
In recent years, soft robotics has surged in applications like wearables, drones, smart fabrics, and medical instruments. Due to their compliance, these devices excel in tasks demanding dexterity and adaptability, such as manipulation, locomotion, crash re ...
EPFL2024Surgical approaches to the capitellum: a comparative anatomic study
Alexandre Terrier, Patrick Goetti, Frédéric Vauclair
Background: Osteochondritis dissecans (OCD) of the humeral capitellum is an important cause of elbow disability in young athletes. Large and unstable lesions sometimes require joint reconstruction with osteochondral autograft. Several approaches have been ...
Mosby-Elsevier2024Near-Zero Parasitic Shift Flexure Pivots Based on Coupled n-RRR Planar Parallel Mechanisms
Simon Nessim Henein, Florent Cosandier, Loïc Benoît Tissot-Daguette, Etienne Frédéric Gabriel Thalmann
Flexure pivots, which are widely used for precision mechanisms, generally have the drawback of presenting parasitic shifts accompanying their rotation. The known solutions for canceling these undesirable parasitic translations usually induce a loss in radi ...
2024Enabling four-arm laparoscopic surgery by controlling two robotic assistants via haptic foot interfaces
Aude Billard, Mohamed Bouri, Walid Amanhoud, Jacob Hernandez Sanchez
Robotic surgery is a promising direction to improve surgeons and assistants’ daily life with respect to conventional surgery. In this work, we propose solo laparoscopic surgery in which two robotic arms, controlled via haptic foot interfaces, assist the ta ...
2023The strength of surgical knots involves a critical interplay between friction and elastoplasticity
Pedro Miguel Nunes Pereira de Almeida Reis, Paul Johanns, Changyeob Baek, Paul Grandgeorge
Knots are the weakest link in surgical sutures, serving as mechanical ligatures between filaments. Exceeding their safe operational limits can cause fatal complications. The empirical nature of present guidelines calls for a predictive understanding of the ...
AMER ASSOC ADVANCEMENT SCIENCE2023Zero Parasitic Shift Pivoting Kinematic Structures Based On Coupled N-RRR Planar Parallel Mechanims For Flexure Pivot Design
Simon Nessim Henein, Florent Cosandier, Loïc Benoît Tissot-Daguette, Etienne Frédéric Gabriel Thalmann
Flexure pivots, which are widely used for precision mechanisms, generally have the drawback of presenting parasitic shifts accompanying their rotation. The known solutions for canceling these undesirable parasitic translations usually induce a loss in radi ...
ASME2023Flexible surgical device with controllable stiffness
The invention relates to a surgical device (10), comprising a tubular outer shaft (12,) and an inner element (14) having an elongated shape, the outer shaft comprising a distal (30a) and a proximal (30b) outer hinges, the inner element comprising an inner ...
2022Evaluation of anterior cruciate ligament surgical reconstruction through finite element analysis
Anterior cruciate ligament (ACL) tear is one of the most common knee injuries. The ACL reconstruction surgery aims to restore healthy knee function by replacing the injured ligament with a graft. Proper selection of the optimal surgery parameters is a comp ...
NATURE PORTFOLIO2022System and method for a microfluidic jet generation from a compact device
The invention discloses systems and methods for generation of microfluidic jets providing a tool for very precise and localized delivery of e.g., medicaments. The proposed solution overcomes shortcomings related to miniaturization of a jet injection techno ...
2021Foot Control of a Surgical Laparoscopic Gripper via 5DoF Haptic Robotic Platform: Design, Dynamics and Haptic Shared Control
Aude Billard, Mohamed Bouri, Walid Amanhoud, Jacob Hernandez Sanchez
Foot devices have been ubiquitously used in surgery to control surgical equipment. Most common applications are foot switches for electro-surgery, endoscope positioning and tele-robotic consoles. Switches fall short of providing continuous control as requi ...
