Thumb Design

Our powered thumb grip and rotation has both novel and intuitive switching (tap left and the thumb moves left, tap right and the thumb moves right). Alternatively, the dynamic mode uses both thumb motors simultaneously which gives direct access to both opposed and unopposed grips.

Smart Switching

There is no need for external Bluetooth, gyro or RFID triggers with our Covvi hand as it is loaded with switching options to give users fast access to a multitude of grips. For example, a user could double-tap four fingers on the desk for quick access to a finger-point grip for typing.

Robust

The digits of the Covvi hand have been assembled entirely out of a combination of stainless steel and aluminum, building upon the lessons learned from Covvi’s predecessors in the industry – fingers are naturally highly vulnerable to danger and so need protecting.

In this same vein, the passive full digit flex capability has been developed so that fingers and thumbs move out of danger when they are struck from the back of the hand.

Integrated Flex Wrist

The Covvi has a built-in flex wrist with a range of +/- 30° featuring a simple push/push lock. This operates using passive spring-loaded technology for natural and fluid usage. The single-sided push/push locking mechanism gives quick access to three locked positions but can also quickly return to passive flex mode. This system works like a ball point pen – simple and quick.

Hand Covers

The water-resistant hand cover is completely integrated and is made from flexible latex, neoprene and impact resistant polymers.

This design, which has been designed to be both attractive and practical, enables flex capability where required but protection where it isn’t, and also prevents glove migration which is inherent with most other hand covers.

Fast And Strong

The Covvi hand has been developed so that prosthetics users no longer need to compromise between dexterity and grip strength. Not only is it capable of both but it is capable of doing both well, with only 0.3 seconds required to achieve a tripod grip and 70N force strength for grip.

E-Paper Screen

The integrated and fully customizable e-paper screen allows direct communication between the user device and the clinician – very useful for mode identification, training and fault diagnosis.

Customize Your Covvi Hand

Covvi understands that your prosthetic becomes an extension of yourself and as such we would like to celebrate your individuality with you, with a selection of customisable options.

You can choose the style from our available range of the clip-on HDPE components that holds the neoprene glove in place.
