Fischer also shows the active components of the series: USB 2.0 adapter, LED connector and robust flash drive.
Overview of medical technology connectors
Maximum light transport in very thin disposable endoscopes
18.11.2019/XNUMX/XNUMX | Schott is ushering in a new era of light for single-use endoscopes with the "Single EZ guide" light guide: The light guide is designed as a plug-and-play component and can therefore be easily, quickly and cost-effectively installed in the overall system. The space-saving use of flexible glass fibers means that a maximum amount of light can be transported to the scene of the action in the very thin light guides.
The fiber-based lighting reduces heat transfer and thus contributes to a simpler medical technology approval. With the Single EZ concept, Schott simplifies the integration of fiber optic illumination and leverages its many advantages for single-use endoscopes. Lighting methods such as direct-LED or plastic fibers reach their technical limits here.
Especially with very thin skopes such as bronchoscopes, rhinoscopes or urethroscopes the available space for lighting is limited. The Schott concept maximizes the amount of light by filling the available space to a maximum through an active area.
A regulated heat management and the increased image quality through better light are further features of the light guide, which has also been reduced in its complaexity.
Biocompatible medical cord without stick-slip effect
29.10.2018 | HEW cable optionally equips its special cables for medical technology, which are used in diagnosis, surgery or patient monitoring, with the specially developed "Silindo" sheathing. Without any foreign material in the silicone or on the surface, this permanently minimizes sliding friction.
Robot Worm milled around corners at head surgery
11.01.2016 | Removing tumors from the inner ear is a tricky business: Doctors usually have to remove the entire temporal bone. In the future, a 5 mm wide tunnel through the bone, which Fraunhofer's mini robot "Niliboro" will cut, will be sufficient. It avoids sensitive areas such as blood vessels and nerves. The robot is held in place during the operation using inflatable cushions. First, the researchers develop the optimal pocket geometry using several prototypes.
Diagnosis of the inner ear tumor - there is no way around an operation. The inner ear, however, is not easily accessible: it is covered by a cranial skull bone called mastoid, also called petrous bone. In addition, many blood vessels and nerves go through the surrounding tissue. The doctors mill so much of the mastoid bone that they have tracked down each of these sensitive structures. That's the only way they can make sure they do not harm them. Mostly this means that the doctors have to remove the entire bone. The resulting hole is filled with fatty tissue from the abdomen after surgery.
Operating through small tunnel
In the future, this operation should be done more gently: Then a small hole of 5 mm diameter is enough to cut the tumor out of the inner ear. This is made possible by the Niliboro (non-linear drilling robot), a researcher of the Mannheim project group for automation in medicine and biotechnology at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, together with its colleagues at the Technical University of Darmstadt, the University of Aachen and of the University Hospital Dusseldorf.
Although there are already drills that can mill a tunnel into a bone - but they make their way only dead straight into the bone. "For the first time, Niliboro can drill around corners," says Lennart Karstensen, project group scientist. This property is what makes minimally invasive surgery of inner ear tumors possible. For if the tunnel had just run, he would come here and there the nerves dangerously close. In order not to injure them, the diameter of the tunnel should not be more than one to 2 mm. However, you can not operate through such a small hole. Niliboro, on the other hand, is able to bend around delicate areas, so the tunnel can be 5 mm wide. Broad enough to do the surgery.
Hydraulic lines make robot worm crawl forward
But how does the worm manage to mill through bones and around corners through the mastoid bone? "The worm consists of a head and a tail," explains Karstensen. »These two parts are flexibly connected via a bellow.« The structure is reminiscent of an extra-long bus, in which the front and rear parts are coupled by a hose-like construction that resembles an accordion.
On its way through the bone, the robot is connected via 8 to 12 hydraulic lines with the outside world, ie the control devices and pumps in the operating room. These lines let him crawl in the right direction: First, they pump hydraulic fluid into three cushions located at the back. The pillows fill the space between the worm and the bones and thus fix the back mini-robot part in place. Now the liquid flows into the bellows: The "accordion" unfolds and pushes the head forward. The worm literally stretches and moves its front part further into the bone.
The drill, which is attached to the head, mills the way freely. Now the rear part is tightened, similar to a living worm: To do so, the cushions are inflated at the front part and hold it while the hydraulic fluid escapes from the back cushions. The pipes now also suck the liquid out of the bellows. He pulls himself together and hauls the back part behind him. Bit by bit, Niliboro works his way forward. »The direction in which the robot should move can be adjusted via the cushions on the front part. If, for example, he turns left, we fill the left cushion less taut than the others, and the robot tilts to the left side, "says Karstensen.
First prototype developed
In the laboratory and later in the operating room, the path that Niliboro is making is being closely monitored: via an electromagnetic tracking system, or EMT for short, developed by colleagues at the Technische Universität Darmstadt. In addition, a computer tomograph sporadically takes pictures and checks the position.
The researchers have already built a first prototype. At the moment he is five times bigger than the planned final version. For the time being, it consists only of the front part and bellows, so the heart of it. Bit by bit, the scientists want to optimize and expand the prototype. Is the complete technology, Niliboro should shrink to its final size. In two years, the researchers hope, the doctors could test the mini-robot for the first time.
Palletizing system handles endoscopes for medical technology
16.03.2014 | With the "Variostack", IEF-Werner has developed an open and modular palletizing system that can be tailored to any task. The user can operate the palletizer with integrated product handling or connect it to an existing robot or handling system. In addition, the extremely compact palletizer can be loaded with pallet trucks or conveyor belts as standard - with the belt loader version even from the side. This palletizing system is already in use, for example, at a manufacturer of medical technology products.
Raw parts that are to be transported from a production line to an affiliated assembly line, the user can provide oriented with the palletizing system Variostack and feed in a predetermined position for further processing. After assembly, the palletizing system retrieves the finished parts from the processing line.
Depending on the application, the palletizer is equipped with single or multiplegrab fitted. It can be adapted to different tray sizes - in particular to quarter or eighth euro pallets. The system processes loaded pallets with a maximum weight of up to 10 kg. The repeatability of the pallet table is ± 0,05 mm. The pallet change takes less than 4 s.
IEF-Werner GmbH from Furtwangen in the Black Forest has designed the palletizing system in such a way that the user can respond flexibly to different space conditions and conditions in the production hall. For example, the system can be loaded with pallets from the front via a conveyor belt as well as a cart or from the side via a conveyor belt - with the same basic design. In addition, several palletizing systems of this type can be combined with each other.
Space-saving design
To make the system as space-saving as possible, the control cabinet was installed in the system. This is made possible by intelligent components - for example, motors with integrated amplifiers or special cabling. In addition, all danger spots are covered. With space requirements of less than 1 m², the palletizer can be easily integrated into any existing production structure.
The system is controlled either with a control provided by the customer or with the PA-Control Touch from IEF-Werner, which combines the positioning and sequence control with the display medium in one device. This means that the palletizing system can be operated effortlessly and in a way that is easy to understand. Commissioning and programming take place via an Ethernet interface with the manufacturer's own software package "Winpac". The PA-Control Touch combines the advantages of an NC control with those of a PLC. In this way, it guarantees a high level of machining accuracy and repeatability.
Insert endoscopes for laser marking
This palletizing system is used, for example, by a manufacturer of medical technology products in order to feed pallets filled with endoscopes with dimensions of 600 x 400 mm to a robot for laser marking. To do this, the operator places a stack of loaded pallets on the infeed conveyor, which then automatically feeds them into the system. In order to separate the pallets, a lifting axis moves down to the pallet stack.
Since three different pallet heights are to be processed unsorted in the stack, there is a barcode on the front of each pallet containing information about the pallet height and the exact content. To read this information, a barcode reader was installed on the pallet grabber. This sends the information to the PA-Control Touch control, which in turn transmits it to the robot controller via the bus system.

Subsequently, the isolated pallet are transported upwards and brought into the processing position. There, a robot from the customer takes the products, labels them and then places them back in the pallet. Another lifting axis with pallet gripper picks up the machined pallet and places it on a conveyor belt that drives it out of the system. A crash lock on both pallet grabs prevents a collision when driving down when a stack of trays is not positioned correctly.
To ensure that the pallet grippers do not collide with the tray stack - if it is not positioned correctly - they are equipped with a crash protection device. To provide extra protection for the operator, the specialists have also secured the danger area behind the feed chutes of the infeed and outfeed conveyor with a light curtain. An additional, movable protective cover allows a trolley or stack to be changed without interrupting the parts handling.
3D technology was introduced into the medical endoscopy
26.03.2013/XNUMX/XNUMX | Patient-friendly, minimally invasive procedures, such as laparoscopies (abdominal endoscopy), are unthinkable without high-resolution imaging techniques. Two-dimensional, i.e., surface-level views of the body have been established in endoscopy for years. Three-dimensional images, as seen in the movies, were denied to surgeons for a long time. The new "Einstein Vision" laparoscopy system from Schölly Fiberoptic, together with the high-precision drive technology from PI (Physik Instrumente) Micos integrated into the handle, ensures a more atraumatic operating world.
Miniature gears and micromechanics for positioning tasks
27.09.2012 | Micromotion manufactures micromechanical components and the world's smallest backlash-free Precision gear and precision motors for linear and rotary positioning tasks. The compact design and the high power density of these Miniature gear are particularly suitable for demanding applications in the Medical Technology.
The micromechanical components are used as miniaturized control mechanisms, for example in endoscopes. Integrated into fully encapsulated micro gears, they are used under extreme environmental conditions. Examples of the high precision gears can be found in UHV or sterilizable applications. As high-precision multi-axis positioning systems in the smallest of spaces, the gears also handle positioning tasks in microscopy Resolutions in the lower nm range.
