Design, Kinematic Optimization, and Evaluation of a Teleoperated System for Middle Ear Microsurgery

Middle-Ear Microsurgery Simulation to Improve New Robotic Procedures

Otological microsurgery is delicate and requires high dexterity in bad ergonomic conditions. To assist surgeons in these indications, a teleoperated system, called RobOtol, is developed. This robot enhances gesture accuracy and handiness and allows exploration of new procedures for middle ear surgery. To plan new procedures that exploit the capacities given by the robot, a surgical simulator is...

Mechanical Design and Optimization of a Microsurgical Robot

The tele-operated system with three arms for the microsurgery of the middle ear is composed of an operator console from where the surgeon tele-operates three robotized arms that hold surgery tools with a high level of accuracy. The main difference between these micromanipulators and the conventional minimal-invasive surgery robots is the increased field of vision capacity to carry out complex o...

Middle Ear and Mastoid Microsurgery - Sanna / Sunose / Mancini, Preamble

Optimization of the Kinematic Sensitivity and the Greatest Continuous Circle in the Constant-orientation Workspace of Planar Parallel Mechanisms

This paper presents the results of a comprehensive study on the efficiency of planar parallel mechanisms, considering their kinetostatic performance and also, their workspace. This aim is approached upon proceeding single- and multi-objective optimization procedures. Kinetostatic performances of ten different planar parallel mechanisms are analyzed by resorting to a recent index, kinematic sens...

Passive and active middle ear implants

Besides eradication of chronic middle ear disease, the reconstruction of the sound conduction apparatus is a major goal of modern ear microsurgery. The material of choice in cases of partial ossicular replacement prosthesis is the autogenous ossicle. In the event of more extensive destruction of the ossicular chain diverse alloplastic materials, e. g. metals, ceramics, plastics or composits are...
