Rehabilitation equipment technology and prosthetics
Rehabilitation devices are becoming increasingly important due to medical advances and an aging society. The aim is to enable patients to recover effectively but gently. This requires drive systems that support gentle, patient-friendly movements, can be controlled precisely, and replicate natural movement patterns as realistically as possible. In prosthetics, the combination of robotics, bionics, and medical technology is opening up completely new possibilities. Bionic hand prostheses are becoming increasingly compact, powerful, and suitable for everyday use. The drive solutions used must be lightweight, compact, and unobtrusive in order to provide the best possible support for users in their everyday lives.
speeroX gearing for bionic hand prosthesis
Bionic hand prostheses use bionics and neurotechnology to mimic the natural movement and function of the hand, enabling people to perform everyday tasks again after amputations, injuries, or congenital malformations.
To enable precise gripping and positioning of the hand, a key requirement for the gear components of such a hand prosthesis is their torsional play. In this context, sufficient power must be transmitted in the very limited space available to ensure reliable operation. With its high power density and efficiency, speeroX is therefore ideal for this application. This means that bionic hand prostheses can contribute to the quality of life of those affected in a durable, reliable, and economical way.
Advantages of speeroX for use in bionic hand prostheses:
- Minimized installation space for compact integration into the overall system
- Increased efficiency for a reliable system
- Low backlash for precise movements
Drive systems for motorized shoulder movement rails
Rehabilitation after shoulder surgery requires the utmost precision. In a motorized shoulder movement splint, two worm gears control the movement: one gear raises and lowers the arm, while the second performs the rotation of the shoulder. Precise manufacturing with a total backlash of less than 1.5° allows movements to be performed safely and gently beyond the top dead center—a crucial factor in avoiding pain and providing optimal support for recovery.
The advantages at a glance:
- Precise motion control with minimal overall play of less than 1.5°
- Separate lifting/lowering motion and shoulder rotation thanks to two precisely coordinated worm gears
- Smooth, patient-friendly motion sequences that correspond to natural movement patterns
