Journal ArticleDOI
An active hybrid parallel robot for minimally invasive surgery
TL;DR: The paper presents the kinematic and dynamic behavior of a parallel hybrid surgical robot PARASURG-9M and some numerical and simulation results of the developed experimental model with its system control are also described.
Book ChapterDOI
Design Issues for an Inherently Safe Robotic Rehabilitation Device
TL;DR: A preliminary design solution is proposed based on a cable-driven parallel architecture, which can provide the required operation workspace and significantly improve the safety of the rehabilitation procedure as compared with exoskeletons or traditional robotic devices.
Journal ArticleDOI
Development of inverse dynamic model for a surgical hybrid parallel robot with equivalent lumped masses
TL;DR: In this paper, the authors presented the inverse dynamic model (in the case of using the laparoscope as a surgical instrument) and some characteristics of a 5-DOF hybrid parallel robot designed for minimally invasive surgery.
Journal ArticleDOI
Kinematic modelling of a 5-dof hybrid parallel robot for laparoscopic surgery*
TL;DR: The kinematic modelling of a 5-degree of freedom hybrid parallel architecture in two slightly different variants of this structure is determined, and following the analysis of singularities, the best variant is chosen.
Journal ArticleDOI
Orientation module for surgical instruments—a systematical approach
TL;DR: The design and analysis of a new module for the orientation of the instrument tip in minimally invasive surgery point out the advantages of the proposed solution: increased ergonomics and dexterity, wider workspace, reduced number of incisions.
