VIVOS: Everyone’s glad it exists, but no one wants to get to know it personally
Presumably, everyone has at some point wondered what it would be like if they could no longer see. To reduce the likelihood of this happening, Geuder AG’s VIVOS product has recently been launched on the market to assist eye surgeons in ophthalmic surgery. Working in close collaboration, we have developed both the trolley and the multi-patient cassette for this purpose.
It makes you shudder when you read the description of an ophthalmic surgical procedure. In such an operation, small needles are used to puncture the eyeball. Here it is important that the products used guarantee an extremely high level of quality and convey safety.
For this reason, at the turn of the year 2025 we began with the development of the VIVOS cassette. As it is a consumable product with a limited period of use, one focus during development was on reducing manufacturing costs. Another focus was on optimizing the pressure-sensitive fluid circuit. Here, even the smallest pressure fluctuations can cause severe damage to the eye, which quickly led to the choice of using a peristaltic pump. This then had to be combined with a suitable measurement concept. Several conceptual approaches for pressure measurement were theoretically compared and evaluated. The favored concepts were then worked out in detail and validated using functional models. The smallest pressure fluctuations were to be detected by the measurement technology, communicated to the electronics, and converted there into new control signals for the peristaltic pump. This development took place in close cooperation with Geuder and an electronics developer.
In spring 2025 we then began the development of the cart. There was already a preliminary development from Geuder. This had to be optimized with regard to the right compromise between aesthetic appearance, function, and manufacturing costs. Due to the manageable quantity per year and the size of the cart, some manufacturing processes were quickly ruled out. This did not make the development of the housing any easier. In the end, a manufacturing process that is otherwise used more in prototype construction or in initial small series was chosen. The art now lay in reconciling the manufacturing tolerances and the requirements of this production process with the product requirements. Another challenge with the cart was implementing the connection of the swiveling tray. The connection to the frame had to compensate for considerable leverage forces when the tray was extended and loaded. In addition, the joint concept of the arm had to allow it to swivel into the very spatially limited storage space in the cart.
Both developments were also subject to a very tight overall schedule. This was due to the fact that fixed time slots had been booked with the approval and certification authorities. Despite this time pressure, collaboration in development was always cooperative and constructive. We are therefore pleased that this product is now finally on the market and that, with its elegance and impression of quality, it will hopefully convince all customers.
