AI Technical Summary

⚠Technical Problem

Users with limb impairments face challenges in unassisted donning of orthotic devices due to specific difficulties in grasping and picking up objects, making the process slow and difficult.

⚗Method used

A reconfigurable hand orthotic device with a hand module featuring a hand shell, finger shell, thumb shell, and a hand strapping system that includes dorsal and thenar strapping arrangements, along with a grasp actuator, to facilitate secure and efficient donning through top-down or slide-through methods, utilizing adjustable straps and a pivot mechanism for relative thumb and finger motion.

🎯Benefits of technology

The device enables easy and secure donning of the orthotic device, accommodating various hand sizes and shapes, and allows for relative motion of the thumb and fingers, enhancing user convenience and rehabilitation support.

Abstract

A hand module of an orthotic device assists a user with an impaired ability to grasp and pick up objects. The hand module comfortably secures a user's hand in a hand shell and is configurable by a clinical professional at the time of delivery for one of two different donning methods, a top-down method and a slide-through method. In the top-down (or dorsal) method, a user's palm is positioned on top of the hand shell and strapped in from above. In the slide-through (or thenar) method the user's hand is pulled through a pre-formed upper loop and strapped around the user's thumb from below. The hand module is configured with a grasp actuator that can move between an open latched position and a closed unlatched position by pushing a lever or by pulling on the grasp actuator with force exceeding a threshold value.
