HapticMed Haptic Feedback in Medical Applications

Project Director: Felix G. Hamza-LupArmstrong Atlantic State University

Executive Director: Dorin M. Popovici

Background

Haptic - sense of touch – bidirectional (I/O)

Has 2 components: Tactile Force/torque feedback

Haptic Devices – simulate sense of touch

6 force/torque DOF feedback system offers: 3 – force – translations 3 – torque – rotations


Practice-based Learning – Surgery

Learning in a safe environment where mistakes can be safely made

Force/torque feedback can provide benefits (both passive and informational)

at little cost to cognitive demand because of its intuitive nature

refine the required skills until the operator reaches a target level of proficiency before commencing training via the traditional apprentice model upon patients

Surgical Training Application

Set of tools for basic surgical skill acquisition

First module Liver Diagnostics through Palpation

Liver palpation can be used in diagnostics of: increased diaphragmatic descent; presence of a palpable caudate or Riedel's lobe; presence of emphysema with an associated depressed

diaphragm; thin body habitus with narrow thoracic cage; fatty infiltration (enlarged with rounded edge); active hepatitis (enlarged and tender); cirrhosis (enlarged with nodular irregularity); hepatic neoplasm (enlarged with rock-hard or nodular

consistency).
