Good experience with modern 4K camera technology

In medicine, successes and advances are closely linked to technical innovations. This is particularly true for surgical disciplines, where minimally invasive surgery, so-called keyhole surgery, has now become established. For several decades, Siloah St. Trudpert Klinikum and Richard Wolf, a medical technology company specializing in endoscopy systems, have been working together to advance optimizations.

“We experience first-hand how our instruments support us in our daily operating routine. In direct exchange, the surgeons let us know where they see potential for optimization and what works very well. This is valuable feedback for us, which comes directly from the operating room and is incorporated into further development. For example, the development of the new ERAGONstitch generation of needle holders, from the first hand sample to the final product, was accompanied by PD Dr. Schulz and his entire surgical team.”

– Jürgen Steinbeck, Managing Director

The long-standing, good cooperation is also an important factor for the doctors in their work. Sales representative Matthias Fröhlich from Richard Wolf is a frequent and welcome guest at the hospital. “Technical improvements not only make the surgeons’ work easier and can improve it, they ultimately benefit all patients. Every optimization also increases patient safety,” Matthias Fröhlich summarizes.

A simple but concrete example: the quality of the display on the OR monitor. The clearer the surgical area is transmitted on the screen, the better even small details can be recognized by the surgical team and the safer the procedure can be for the patient. Since the first endoscopic 4K tower with the latest technology and 4K resolution was installed at Siloah St. Trudpert Klinikum back at the end of 2017, the surgeons have had consistently positive experiences. Every day, for example, the team at the Clinic for General, Visceral and Minimally Invasive Surgery uses the 4K surgical towers to perform not only routine operations such as gall bladder removals and hernia operations, but also complex procedures on the stomach, pancreas and lungs.

4K: This means four times the resolution of Full HD. The abbreviation 4K stands for 4,000 and refers to the approximate number of horizontal pixels/images. The result is clear, razor-sharp images at maximum brightness, above-average contrasts and an expanded color spectrum. This display enables a better spatial depth effect and relaxed viewing for the viewer. “The smallest differences and details are made visible – this makes our surgeons’ work immensely easier,” PD Dr. Tim Schulz, Chief Physician of the Clinic for General, Visceral, Thoracic and Minimally Invasive Surgery, is enthusiastic about the high image quality.

“Especially for complex operations on the intestine, liver, lungs or stomach, this technology is the new standard and offers optimal surgical conditions.” In the context of bariatric surgery (surgery to treat morbid obesity), for example, the structures are nevertheless excellently visualized by the modern imaging despite being restricted by obesity. These positive experiences with the endoscopic 4K tower from the Richard Wolf company in Knittlingen have convinced the chief physician and his surgical team to such an extent that 4K technology is standard in the operating rooms at Siloah St. Trudpert Klinikum.

From biopsy forceps to uretheroscopes: gynecological, urological and orthopedic surgery also rely on Richard Wolf instruments. Currently, the team of head physician PD Dr. Schulz is increasingly performing endoscopic procedures using ICG (indocyanine green)-supported fluorescence imaging in real time – also optimized to 4K. This uses green light for detailed image information and improved spatial depth. “In this process, the intravenous administration of a specific substance (ICG) and a special image information processing method provide tissues such as tumors with detailed and high-contrast images, making it easier to distinguish them from healthy tissue,” explains PD Dr. Schulz.

Furthermore, ICG fluorescence can be used to visualize and reproduce the blood flow to structures such as the colon during colorectal surgery. This can reduce the risk of serious complications. “The possibility of highlighting the blood flow and the anatomy even more clearly in this way and displaying them in a focused manner is an additional plus point for surgical work,” Matthias Fröhlich points out. Dr. Ingo Thalmann, head of the gynecological clinic, and Prof. Dr. Stephan Kruck, head of urology, confirm the advantages for their surgical disciplines.

In addition to fluorescence-assisted surgery, the topic of “more vision” is also a major theme in the cooperation between the hospital and Richard Wolf GmbH in the Department of Urology. The “System blue” used in the area of bladder cancer screening enables so-called “blue light diagnostics”, in which the use of fluorescent blue light significantly improves the detection of certain bladder tumors – compared to pure diagnostics under white light. The procedure is called photodynamic diagnostics (PDD) and has been practiced very successfully at the hospital for many years. “Light cells in the tumor cells are activated and appear fluorescent, making them easier for the surgeon to perceive and control during the procedure,” says the chief urologist.

Future-oriented partnership

Impulses for new, future developments and joint projects do not only come from the operating room; events can also provide the impetus, as the example of the Corona pandemic shows. Together with Dr. Thushira Weerawarna, Chief Physician of the Clinic for Pneumology, Respiratory and Sleep Medicine, several digital workshops have taken place since last year. These have covered bronchoscopy with Covid-19 and airway management with the latest generation of flexible sensor bronchoscopes from Richard Wolf. The experience of two pandemic years by Dr. Weerawarna and his team, along with feedback from physician colleagues, gives a very good overall picture. “The goal is to expand such events, digital as well as live, in the future and to conduct bronchoscopy workshops worldwide together with Dr. Weerawarna,” says Jürgen Steinbeck.

Cost savings through digital hydraulics service



The CytroConnect Solutions service offering from Bosch Rexroth helps recycling companies avoid high downtime costs or even contractual penalties. The customized packages of real-time monitoring, data-based analyses, and complementary spare parts management maintain the availability of hydraulic equipment such as scrap shears, shredders, and presses. At the same time, the intelligent combination of cutting-edge IoT technology and hydraulics expertise minimizes maintenance and extends machine life.

The reuse of raw materials is a permanent fixture in the economy. As part of the supply chain, however, it also leads to high deadline pressure and, not least, requires seamless availability of shredders, scrap shears and presses.

If hydraulically driven recycling machines such as shredders, scrap shears or presses fail, there is a threat of contractual penalties. If trucks, trains or ships have to wait for the load, the consequential costs quickly climb into five to six figures. Acute shortages of skilled workers and the simultaneous supervision of distributed sites cause unnecessary delays in maintenance. In addition, recycling companies lose service life, material and budget if they replace hydraulic parts on a fixed cycle as a precaution. Bosch Rexroth counteracts all these economic disadvantages and financial risks with the three service packages CytroConnect Monitor, Maintain and Predict.

Flat rate against failures at a fixed monthly price

Plant operators achieve the highest possible availability and service life of components with CytroConnect Predict. Using predictive analyses and detailed status reports, the experts make maintenance recommendations at such an early stage that the affected components can be replaced in a planned manner. This reduces the user’s previous maintenance effort by up to 50 percent. Complementary services such as complete spare parts management with guaranteed delivery within 24 hours further optimize availability. The service fees usually pay for themselves within a year, but depending on the application, they can also be recouped with a single avoided downtime, as the following real-life example shows:

Through predictive analytics and predictive maintenance of scrap shears, an international company with over 100 distributed yards can avoid high downtime costs. Previous downtime costs per case were around 600 euros, plus penalties of up to 100,000 euros per day if shiploads of steel bales did not leave for overseas on time. Wear on the shear is detected at an early stage on the basis of the pressure peaks and torques on the electric motors, so that the operator can replace the tool in a planned manner in the future. The far-flung maintenance staff is sustainably relieved and now needs less time for troubleshooting, maintenance, planning and spare parts procurement. In addition, monitoring saves electricity costs because the system avoids operation with increased energy consumption.

In another use case, a recycling company avoids unplanned shutdowns and subsequent costs through predictive analysis of waste shredders. The shredded waste has since been delivered on time again as fuel to a cement plant. Previously, frequent failures of hydraulic pumps and electric motors resulted in regular penalties and additional costs for temporary storage of the delivered waste. The maintenance department, which was suffering from a shortage of skilled workers, was relieved of this burden in the long term.

In addition to the all-inclusive CytroConnect Predict service, Bosch Rexroth also offers the basic CytroConnect Monitor package, which provides pure real-time monitoring with access to historical data from the last 24 hours. As an introduction to the topic of rule- and data-based analyses, Bosch Rexroth recommends the CytroConnect Maintain package. The service package monitors the condition of components in the background using predefined rules, warns of damage via push messages, and supports the continuous optimization of applications with regular performance and usage reports.

All three service packages already include the respective required dashboards and sensors. Recycling companies benefit quickly and easily from intelligent and sustainable failure protection.

Transparent and efficient processes with QM software



Focus on user-friendliness 

Working with people requires a completely different understanding of quality than in the manufacturing industry. Social, communicative and interpersonal goals are in the foreground, but at the same time social institutions must also meet business and legal requirements. A well-structured quality management system supports social service providers such as Lebenshilfen, welfare associations, operators of day-care centers or operators of other social facilities.

ConSense’s software solutions stand for transparent, user-friendly quality management and integrated management systems. The software helps to make processes clearer and more efficient, to clearly define responsibilities and to fulfill documentation requirements. At the same time, the management system facilitates compliance with the standards and guidelines applicable to the respective facility. The ConSense software solutions have been developed with a special focus on user-friendliness and the mapping of realistic processes. Employees can navigate quickly and intuitively on the clear interface, and a comprehensive search function guides them directly to the desired content. 

Software-supported quality management saves time

The QM software enables complete electronic QM documentation with automated, intelligent document control. Further automations, such as the targeted distribution of information, the request for notifications and the revision and archiving of documents, significantly reduce the administrative workload for employees. At the same time, the software offers integrated process management including a process editor for simple and fast process modeling. This simplifies the continuous improvement of processes and the transparency and clarity of documentation increase. 

QM software for social institutions with many locations

Management system software solutions are suitable for organizations of all sizes. With a wide range of functions, interfaces and configuration options, they can be optimally adapted to the needs of the respective institution. The IMS ENTERPRISE solution, for example, is ideal for setting up an integrated management system in facilities with multiple locations or complex organizational structures. All applicable standards and regulations are systematically mapped under a uniform interface and compliance with specifications is supported.

In addition to the quality management standard DIN EN ISO 9001, many other standards or guidelines are also relevant in the social sector, such as DIN EN ISO 45001 (occupational health and safety), HACCP (hygiene concepts in relation to food), DIN EN ISO 15224 (quality management in healthcare), KQT (Cooperation for Transparency and Quality in Healthcare) and the AZAV regulation (Accreditation and Approval Regulation for Employment Promotion). An Integrated Management System helps to harmonize these and thus also makes it easier to meet the criteria for accreditations or certifications.

The solutions for QM systems and integrated management systems from the Aachen-based software developer can also be supplemented as required with modules, such as for measures management, audit management, training management and many more, and thus specifically tailored to the requirements of the organization.

Easy roll-out, mobile deployment

These software solutions can be rolled out quickly and flexibly within the company. The ConSense PORTAL is a web-based management system solution for which the company can also provide hosting. The web application simplifies and accelerates the roll-out compared to desktop applications. Since it can also be used on the move, it is particularly suitable for social institutions whose employees work with the system regardless of time and location.

Microcomputer brings water data to cell phone



Andreas Scharf, a computer science student from Coburg, uses microcomputers to network elevated tanks in the water industry. This is how he became a company founder in Lower Franconia. Water is one of the most precious resources of the blue planet. Today, the waterworks of cities and municipalities measure all relevant data in their plants to ensure supply and quality, and this is now mostly done digitally. However, only stationary on site. Not networked.

“People control their coffee machine and the light via cell phone. But for the community’s elevated tank, which stores the drinking water and cost a few million euros: There’s no proper app for that!”

– Andreas Scharf

The student found it unbelievable that a water custodian can’t see the status online at any time. So he developed an affordable, modern solution for municipalities himself. That was the basis for founding his company frapp.

Waterworks all over the world

In addition to his studies at Coburg University of Applied Sciences, Scharf worked at Energie- und Wasser-Technologie EnWaT, a water system builder based in Stettfeld, Franconia (Haßberge district), whose customers include industrial companies and municipalities all over the world – with different, very individual needs, focuses and problems. Is there a leak somewhere, did the refilling during the night perhaps not work out? What is the water level right now? Or a question that is particularly crucial for health departments: What is the temperature development? To check something like this, there is often only one option: get in the car and drive to the elevated tank. At EnWaT, the digitalization of water treatment and supply systems has been discussed in a very innovative way, Scharf explains. “It’s not that there are no apps at all. For example, the major control system manufacturers offer software to visualize the data. But then what does it mean when a curve breaks in? That’s what municipalities need.” And that was Scharf’s approach: “I’ll put the data on your phone and also tell you what you can do with it.”

Applied science

He taught himself the basics of programming as a teenager. “There was a book on Java lying around at home – I tried that out.” Back then, he went to Realschule, then switched to FOS, graduated from high school in 2018, and started his bachelor’s degree in computer science at Coburg University of Applied Sciences right after that. As part of the Communication Systems event, Scharf attended an IoT workshop with Prof. Dr. Matthias Mörz and dealt with the very topic that the waterworks are missing. IoT, the Internet of things, makes it possible to network physical and virtual objects.

So, for example, the high water tank and the app on the cell phone. Mörz likes his student’s solution: “It’s just nice to see how he lives the basic idea of applied science,” says the professor. The technology of Scharf’s “HBBox” for elevated tank digitization consists in particular of a circuit board that translates information from existing industrial sensors for microcomputers. It allows the data to be stored in a cloud via cellular or the free wireless standard LoRaWan and, for example, a push message pops up in the app when special events occur. “The municipality has access to the data at all times – regardless of where the employees are. Irregularities can be detected right away,” says Mörz. Digitization helps prevent water losses.

High water tank in your pocket

The high water tank in Scharf’s home municipality, for example, is fully networked. Scharf can access it from Coburg. He looks at his cell phone, frowns “There’s a lot going out right now for the noon hour. Maybe a fire call.” In any case, the waterworks knows: what flows when is absolutely transparent in Stettfeld. Scharf brought the elevated tank into his back pocket. EnWaT, the company where he got a lot of input on plant technology as a working student, is now his customer, and so Scharf’s digitization technology was also used during the floods in the Ahr Valley in 2021, when the company deployed a mobile waterworks in a shipping container there. Scharf founded his own company, frapp, in 2020. He shrugs his shoulders: “The first Corona summer. You didn’t have much else to do then.” He was 19 at the time. Today, he’s thinking about other fields of application for his HBBox: “We can digitize not only in the area of drinking water. I could also cover sewage treatment plants.”
