Taska Handgen 2: Waterproof myoelectric hand prosthesis from Taska Prosthetics

You can clean, shake hands at work again and even perform activities that require flexible fingers and wrist. The wrist can be separated. Dual release buttons make changing hands much easier and faster, improving grip security and preventing unwanted wrist separation. Compatibility with all industry-standard QD lamination cuffs, as well as the wrist rotation system, means you can start using the Taska QD right away. Thanks to coded, laterally compliant fingers and high-speed thumb rotation, the TASKA HandGen2 is waterproof beyond the wrist - without the need for a glove. The TASKA Hand offers users over 20 selectable grip patterns. The hand is available in two sizes and two wrist variations. The hand can be controlled either by muscle signals and / or a multifunction switch on the back of the hand.

Three pre-programmed grip patterns with three main grips can be pressed on a button on the back of the hand as standard. Five additional grips can be switched by pressing a key. The change of thumb position from opposition position to lateral position changes automatically depending on the grip pattern.

One can individualize the grip patterns to his needs through the own TASKA app. The TASKA hand is certified according to standard IP67. Cosmetic cladding of the hand is not available.

The Taska Hand App guarantees extreme ease of use.

The waterproof prosthetic hand protects the user from costly damage to the fingers. Due to the unique overload protection in the knuckles, the prosthesis prevents costly damage to the fingers.

 The core of this technology is based on the laminating cuff, because it is the key to a waterproof connection of the wrist.

TASKA is designed to provide EMG electrodes, pattern recognition systems and compatibility with all industry standard quick release grippers to give orthotists and users more options.

Fields of application of the Taska hand prosthesis:

• Activities that require hands to be briefly wet or immersed in water
• Wash hands
• Washing dishes
• Car wash
• Walking in the rain
• Use of a garden hose
• Activities that involve vibration of the hand
• Use of motorized garden equipment, e.g. lawn mowers,
• Use of small or medium size power tools
• Activities that place moderate strain on the hand, e.g.: light gardening, carrying a suitcase
• Low-impact work in the workshop
• low intensity sports activities

Thanks to the intuitive grip strength control, you can perform precise movements and pick up fragile objects safely and hold them in your hand.

All TASKA hands are equipped with HydrosealTM technology to achieve IP67 waterproofing, so they can be immersed in water up to the buttons of the movable wrist.

In addition, with the following TASKA hands equipped with HydrosealTM technology in the wrist, the hand and wrist can be immersed in water up to the first opening in the prosthetic socket:

• TASKA Hand with low profile (when using the supplied low profile lamination ring).
• TASKA HandGen2 with quick disconnect when fitted with a sealing ring and connected to the appropriate wrist connector. Possible combinations include:
• TASKA sealing ring -> TASKA laminating sleeve
• MC Seal Ring -> Multi-stage motion control forearm end caps and wrists with drive (if purchased after 2019).

TASKA does not guarantee the watertightness of the wrist connection after insertion into the prosthetic socket.
