Grasping simulation with a new device for a hand

Abstract

People with disabilities have limitations in activities of daily life such as grasping a glass of water or moving an object. Orthotic products that improve or restore the functionality of the musculoskeletal system of a patient contribute to some extent to overcome the limitations described. So does the hand brace, used to treat musculoskeletal disorders caused by various diseases (rheumatic disorders, neurological, orthopedic and others). The paper simulates a novel exoskeleton to grasp any object. The novelty of this mechanism is that works without external energy, it works with a wrist movement that generates a kinetic movement and helps to grasp objects with an extra force. Objectives: The aim of this work is to simulate a novel exoskeleton to grasp any object. The orthosis (external devices attached on the hand of a user disabled) facilitate the functionality, being comfortable and easy to be used by the patient. It is adaptable to hand size and finger length of the patient and needs no power source for operation.
