- Fluidhand8 | Vincent Systems
2005 - Fluidhand 8 Up The Fluidhand 8 has 8 drives that are controlled via 5 valves. The bellows in the index finger and middle finger are each hydraulically coupled with each other, and the drives of the ring and little fingers are also connected with each other via a common valve. The special feature of this further development is that the metacarpus has been replaced by a hermetically sealed pressure body. Inside the metacarpus is an elastic tank in the form of a diaphragm, in which both the drive medium (vegetable oil) and the control electronics, valves and pump are integrated; all system components "float" permanently in the drive medium. Between the pressure body shell and the diaphragm there is again a two-phase gas with a constant pressure of 2 bar. The integrated design allows any space reserves in the metacarpus to be used as a fluid reservoir, while at the same time forming a maximum gas volume for preloading the hydraulic tank. The pump can draw directly from the environment and the pump, valves and electronics are optimally cooled by the surrounding liquid. The design makes the hand very compact and at the same time extremely stable. Due to the very flat metacarpus of 30 mm and the short design, the hand achieves an anatomical shape and with only 410 g it is particularly light. The Quicksnap wrist closure makes the prosthesis compatible with all stem systems and their power supply. The prosthesis is controlled by two EMG electrodes integrated in the prosthesis socket. Simple trigger switching signals can be used to switch between pre-programmed grips and the grips can then be controlled proportionally. For the first time, a sense of touch has also been integrated into the prosthesis. The grasping force measured on the index finger via a sensor is transmitted to the system controller, which activates a vibration motor on the hand that transmits coded information to the prosthesis wearer about the force applied. In addition, the Fluidhand 8 serves as a test platform for new prosthesis controls such as grip pattern recognition or motion control using 3D sensors, research areas on which the research center has been working intensively as part of the Fluidhand development.

- Previous model | VINCENTevolution4 Hand Prosthesis | Vincent Systems
Previous model to the VINCENTevolution5: proven myoelectric technology, robust, lightweight, and waterproof. VINCENTevolution4 World leader at all levels WATERPROOF The world's first waterproof hand prosthesis according to IP68 (protection against prolonged submersion) EXTREMELY LIGHT The world's lightest multi-articular hand prosthesis EXTREMELY ROBUST The world's only prosthetic hand with a complete skeleton made of aluminum or titanium SENSE OF TOUCH The world's first and so far only hand prosthesis with sense of touch EASY OPERATION The world's most intuitive hand prosthesis, in which all grasp types are controlled by muscle signals PRECISION Precise powerful pinch grip enables the gripping of objects as small as ⌀1 mm CUSTOMIZABLE The world's only hand prosthesis in 5 sizes and 25 colour combinations Precision and quality The fourth generation of our hand prostheses, VINCENTevolution4, builds on the successful drive concept of VINCENTevolution3, with further improvements in gripping force and speed. The precision of the grips, the aesthetics and the quality of the hand are outstanding. Sophisticated control system A unique feature is the patented single-trigger control system, which allows all grip types to be controlled uniquely and reliably with fine sensitivity via the muscles alone. The hand does not need buttons on the back of the hand, motion controls or a smart device to select a function or grip. These types of control often take too long in practice, so the desired grips will be performe d more quickly by the natural hand. In contrast, all movements and handle changes of the VINCENTevolution4 are controlled exclusively and directly by the muscles of the prosthesis wearer and are therefore completely independent of the opposing natural hand or second prosthesis. The absence of buttons and the simplicity of the control system allow the user to safely control the prosthesis from any movement and in any situation and to achieve any grip change quickly and without errors. The prosthesis can thus optimally assist the opposite hand and thus contribute its full potential to everyday life. Uncompromisingly waterproof We have been able to implement many innovations with the new generation of hands. For example, the VINCENTevolution4 is the world's first hand prosthesis to achieve the IP68 degree of protection, which means it is uncompromisingly waterproof against continuous submersion up to a maximum of 1.5 meters for a maximum of 30 minutes, with no restrictions on the salt or chlorine content or the quality of the water. Elastic fingers The gel encapsulated fingers run more smoothly and the flexible mounting of the finger base joints allows the fingers to be squeezed together naturally when the hand is slightly spread. This not only makes the hand feel more natural, but the flexibility of the fingers also makes them much more robust and resistant to all kinds of stress. Adaptive shell For the first time, the shell of the metacarpus consists almost entirely of an elastic, high-strength material. The soft surface and its excellent adaptive properties significantly improve both the feel and the grip. In particular, the soft knuckles relieve the hand during support and extend the service life of the optionally available lifelike textile-based cosmetic gloves. A special innovation is also the completely dust-tight covering of the finger and thumb base joints. All openings of the hand have been closed by space-saving visor-like joint solutions. The optimized finger and thumb tips have been given finger nails and flattenings that enable even more precise gripping. The index finger is touch-screen compatible in the proven manner. Control with up to four muscles For the first time, a hand prosthesis has an integrated four-channel control system that allows up to four EMG sensors to be connected directly to the hand. The user can choose between two control variants: the single-signal control, in which all grips can be reached without problems and errors with only one switching signal, or the multi-channel control, in which several switching signals can be used to directly control the different grips. Controlling a bionic hand prosthesis has never been so easy and safe. Sensitive sense of touch A vibrotactile sense of touch has been integrated as standard in all VINCENT hand prostheses since VINCENTevolution1. The patented feedback of touch and gripping force provides the user with tactile information about finger strength through gentle coded vibrations of the hand, which are transmitted to the prosthesis shaft, and thus a feeling for the artificial hand. Gripping even fragile objects or sensitive control of the gripping force even without a direct eye contact to the object expand the options for the user. The extended hand feedback also stimulates the user's sensorimotor cortex, which can help reduce phantom limb pain. Tastes are different Five different basic colors give the VINCENTevolution4 an individual and unique design. The colors black, white, pearl white, transparent and natural are each available in combination with four different metal colors and titanium. 25 color combinations can be put together. A color change of the colored silicone parts is possible at any time. Less is more The smallest version of the VINCENTevolution4 XS weighs only approx. 390 g, making it not only the smallest and most stable multi-articulating hand prosthesis with 6 motors currently available, it is also by far the lightest.

- Fluidhand1 | Vincent Systems
1998 - Fluidhand 1 This first soft hand consists of thin foil layers, which have been joined together to form more complex drives in a sandwich construction. Five fingers, built up from 6 foil layers each, functionally welded in pairs, with the middle two foils forming the skeletal structure filled with epoxy resin. The outer two foil layers each form a fluidic muscle. For this purpose, two thin films were welded together in such a manner that chambers were formed in a row and connected to each other. When this structure is inflated with a gas or liquid, it contracts by about 20 % of its length, similar to the natural muscle, and the finger curls up like a bow. After a practical semester and his diploma thesis at the Karlsruhe Research Center (now KIT), Stefan Schulz graduated with a degree in electrical engineering and device systems technology from the University of Rostock and took up a position as a research assistant at the Research Center. Already as a student at the University of Rostock, Schulz worked on the development of alternative miniature drives and patented a process for the production of planar fluid drives on a foil basis. At the Research Center, he continued developing this technology, particularly targeting applications in the field of fluidic robotics, so-called soft robotics in the environment of medical technology research topics. The aim of the work was to develop new drives for instruments used in minimally invasive surgery. Schulz's first applications for the new technology were flexible fluid actuators, miniature catheters for diagnostics, endoscope guidance systems for minimally invasive surgery and diagnostic colonoscopy systems. Fluidhand 1 was created as a “by-product” during the development of a camera guidance system for laparoscopy. The same artificial muscles that enable the movement of a laparoscope camera also work in the Fluidhand 1. In this process, two layers of film are welded together in a diamond-like pattern to form a chamber. When a pressure is applied to this chamber, the flexurally limp but stretch-resistant foil layers form circular arcs, resulting in a shortening of the previously flat structure. The artificial muscles formed in this way work as agonist and antagonist in the Fluidhand 1 and enable the artificial finger and thumb to be bent and stretched and stiffened. A single finger can describe a 180 degree arc, but the force of the artificial muscles is very low due to the material and not suitable for holding objects heavier than approx. 100 g. Up

- Fluidhand2 | Vincent Systems
1999 - Fluidhand 2 Up The new planar technology for manufacturing fluidic drives and kinematics was therefore ideally suited for actively moving miniature catheters and endoscopes. However, the forces achievable with planar film drives, which operate at a working pressure of 0.5-1 bar, were too low for the construction of an artificial hand. To generate higher grasping forces, a correspondingly higher working pressure had to act in the fluidic drives. For Fluidhand 2, “artificial muscles” based on thin silicone hoses were therefore used, which were sheathed with a flexurally flexible, stretch-resistant fabric made of polyamide. The tubes of the Fluidhand 2 were unfolded in the finger joints. When subjected to an overpressure of up to 4 bar, the joints expanded unilaterally and realized a curvature in the opposite joint direction. Each finger of the hand has two pneumatic muscles, the thumb has three, the wrist has four. The extension is done by a rubber band. The joint and support structure in the fingers, thumb and hand, was made of fiber-reinforced composite material. The artificial hand scored with its consistently soft and compliant structure, very fast movements and pronounced adaptability when grasping. The grasping forces achieved were around 2.5 N per finger. Objects heavier than 500 g could not yet be grasped with this hand. As in Fluidhand 1, the hand was driven by compressed air, which meant that a powerful compressor was required to operate the hand. Up

- Fluidhand7 | Vincent Systems
2004 - Fluidhand 7 Up The Fluidhand 7 is designed as an experimental hand. It is used to develop new control methods and to test a new tank system that is capable of storing energy. The hand therefore has one valve for each of the 8 drives. A type of spring accumulator was developed for the hydraulic tank, which allows the hand to be closed quickly and silently without the hydraulic pump operating. Due to the large number of new and experimental components, the metacarpus has turned out to be significantly larger than the previous model, but at this stage of development, the anatomical shape and size of the hand is not a priority. For the hydraulic system, experiments were carried out with a tank that allows energy recovery when the hand is opened. The tank consists of a rigid outer shell and an elastic tank bladder inside. Between the outer shell and the tank bubble is a two-phase gas under constant pressure of 2 bar. In the intermediate space, just enough gas is formed from the liquid aggregate state until a constant pressure is reached. When the hand is opened, gas is formed; when it is closed, it is compressed into liquid, at a constant working pressure of 2 bar at room temperature. The internal diaphragm with the hydraulic fluid is thus under the pressure of the gas. When a valve is opened, a finger joint is already moved without the hydraulic pump having been activated. The pump can then build up even greater grasping force with a time delay. In this way, very dynamic and also noiseless finger movements are possible. When the drives are emptied, the water is pressed back into the tank, against the pressure of the two-phase gas, and the system is ready for the next grasping process. Up
- Fluidhand6 | Vincent Systems
2003 - Fluidhand 6 Up The Fluidhand 6 is a particularly compact version of the hydraulic hand prosthesis, reduced to the essentials. The index, middle and ring fingers are each moved in the base joint via a flexible bellows drive, the little finger is mechanically coupled to the ring finger, and the middle finger is hydraulically coupled to the ring finger. The thumb is actuated in the basic joint. In this way, the thumb and index finger can be moved separately, while the other fingers move together. The 4 drives are controlled by a 3 valve bank, the miniature pump sucks distilled water from a pressure storage tank to pump it into the drive chambers. The weight of the hand is about 350 g. The aluminum fingers were covered with a PU foam. In the basic joints, all long fingers have an elastically mounted abduction. At this stage of development, experiments were carried out with different variants of the fluid hand, with the number of joints and drives as well as the required valves being varied considerably. The aim was to find an optimum between size, anatomical design and weight on the one hand and functionality on the other. Extremely reduced versions with only 4 drives and three valves, such as the Fluidhand 6, were built, which could be designed in this way to be very small, light and anatomical. This version of the Fluidhand is a particularly interesting candidate for a robust prosthesis suitable for everyday use, since the smallest number of hydraulic components was installed here. The systems are very light throughout, but also very complex in terms of the physical effects that occur, such as cavitation or the problem of changing material parameters, especially the elastic drives and connecting hoses in the course of operation, as well as wear and corrosion on the valves and the pump.
