Key Features of The COVVI Hand
COVVI has designed its prosthetic technology around the necessity of functionality and accessibility, for both clinicians and users. The COVVI Hand boasts incredible robustness and versatility to match what’s required for everyday use, all of which is backed by software that provides an unrivalled user experience with a powerful level of customisable refinement.
In order to achieve this, we have ensured our designs are world-leading in their capability, are personalisable to each and every user, can withstand the strength and speed pressures required of a hand for everyday life, and most importantly are easy to use.
In addition to the tough exterior materials (Silicone and High-Strength Polymers) used to protect the internal components, the strength and speed capabilities of the COVVI Hand are on par with market leaders.
By bringing our devices much more in line with the amount of endurance required for everyday use, we provide a much more useful experience for our users.
Ease Of Use
Having a bionic hand that works as close to a human one as possible goes a long way in making it easy to use.
The COVVI Hand has been developed so that prosthetics users no longer need to compromise between dexterity and grip strength.
Passively Flexing Fingers and Thumb
The hand is loaded with switching options to give users fast access to a multitude of grips.
Our digits are spring-loaded to provide impact protection and reduce the likelihood of damage, as well as being manufactured from stainless steel and aluminium for increased strength and durability.
Integrated Flex Wrist
The COVVI Hand 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, as well as helping to reduce strain on the user’s shoulder. This component is integrated with every size of the COVVI Hand.
This system works like a ballpoint pen – simple and quick. The free-flex capabilities also allow for more natural use without additional myo-inputs.
Intuitive Thumb Control
Our powered thumb flexion and rotation has intuitive switching to automatically position the thumb based on the selected grip. The motors are designed to drive simultaneously to provide the end user with access to opposed and unopposed grips.
Using a twin motor design, effective thumb control is achieved in just 0.3 seconds for both full rotation and full-flex travel. COVVI’s thumb design has a passive flex capability (which also applies to all fingers) where we have implemented an intuitive thumb tap trigger and rocker switch.
Our Integrated Glove
The COVVI Glove is made from silicone with a soft-touch coating and boasts thicker integrated fingertip pads, which improves the life of the glove.
Our polycarbonate covers provide another layer of protection and increase its durability, as they’re painted on the inside. Both the glove and covers are easily replaceable in a clinic, with the whole process being both quick and inexpensive.
Innovative Technical Support
COVVI is the first company in the industry to offer remote firmware updates, which can provide new features and bug fixes directly to the user’s hand without the need to go to a clinician, with it only taking approximately 30 minutes to perform a full update.
The integrated E-Paper screen allows the user to display important information, such as the current grip pattern, battery monitor and system notifications.
There is also vital diagnosis data for the clinician too – very useful for mode identification, troubleshooting issues, training information during set-up and fault
