Sheffield, United Kingdom – Researchers from the Medical Advanced Manufacturing Research Centre (Medical AMRC) have helped an orthopedic products company develop a new type of surgical screw that improves the process for surgeons and the lives of their patients.
The development is the brain child of world leading surgeons and Innovate Orthopedics (IO), a new partnership launched to challenge the status quo in the orthopedic sports medicine market by developing products that directly incorporate the insights and experience world leading sports surgeons have gained in the operating theatre to solve problems.
IO asked the Medical AMRC – part of the University of Sheffield Advanced Manufacturing Research Centre with Boeing – to evaluate two new designs it had developed for specialized orthopedic screws.
The screws are designed for specific surgical procedures, including reconstructing the knee’s anterior cruciate ligament, which can be torn during sports that involve sudden stops and changes in direction, such as football, rugby, tennis, skiing and basketball.
Reconstruction is carried out by inserting a piece of healthy tendon in place and securing it to the bone with a screw, over which the bone will grow.
Marcus Crossley, from the Medical AMRC, said: “We worked with IO to combine different aspects of their two designs and create one universal design that reduced the force needed to insert the screw while maintaining fixation.”
“The benefits of using the new screw don’t stop there, however. It helps the surgeon by engaging more rapidly with the ligament and bone when it is inserted and reduces the fatigue experienced by the surgeon and minimizes damage to the replacement ligament”.
The Medical AMRC showed how the universal design could be used to produce a wide range of screw sizes and worked with AMRC partner Star Micronics to develop the complex and unique CNC program that allowed prototype screws to be produced on a Star Micronics sliding head lathe.
Tooling predominantly came from another AMRC partner, Sandvik Coromant and the Medical AMRC also helped IO choose Sheffield Precision Medical to carry out trial production runs and develop the complete range of screws.
Huddersfield-based IO’s founder, Alex Gutteridge, said: “Clinical tests have produced extremely positive results and we are already seeing demand rising among British and international surgeons, who see the benefit of using these innovative, new designs.
“The Medical AMRC didn’t only help us refine our designs and take them into production. It also helped us to create patentable technology which can be further protected by design registration and enabled us to quickly gain ISO 13485 medical devices quality approval and European CE marking.
“Our aim at IO is to create innovative medical devices that solve problems identified by the surgeons in order to achieve better results for their patients, without pushing up costs. The Medical AMRC has played a key part in helping us to achieve that aim with our first product.”

Cleveland, Ohio – The primary driver for multi-parameter patient monitoring equipment in the coming years is expected to be the rising population of the geriatric. With their medical needs already at an all-time high, any increase in the near future will only lead to a significant pressure on the manufacturing rates of devices. This applies especially to multi-parameter patient monitoring equipment due to the growing number of patients suffering from respiratory and cardiac diseases.
Other factors promoting the use of multi-parameter patient monitoring equipment are the advancements in technology created recently that are making them more popular with wireless and mobile device users, and the massive surge of home healthcare services that are causing a high demand for mid- and low-acuity patient monitoring equipment.
The global multi-parameter patient monitoring equipment market is expected to be $3.47 billion for 2016 and should reach $4.65 billion by 2023.
North America continues to take up majority demand
for multi-parameter patient monitoring equipment
By 2023, 51.3% of the total market value of multi-parameter patient monitoring equipment is expected to be taken up by North America. Factors attributed to this majority share include the evolved healthcare system, the high percentage of the elderly, and the specifically higher growth rate of patients with chronic illnesses.
The overall market share held by North America is nearly as consistent as its share in 2014, with a slight reduction. This share has been taken up by the booming demand for healthcare devices in Asia Pacific and Europe. The latter holds a very high percentage of geriatric citizens that need regular monitoring, while Asia Pacific is one of the most promising regions for growth in healthcare devices.
Hospitals to remain key end users of multi-parameter patient monitoring equipment
The function of multi-parameter patient monitoring equipment is to monitor and display relevant patient data for medical assessment. These readings include ECG, blood pressure, respiratory rate, and heart rate. Therefore, the wide utility of multi-parameter patient monitoring equipment has allowed it a high preference in all hospitals across the world. This end-user industry has led the market demand in 2014 and is expected to continue leading it till 2023. Multi-parameter patient monitoring equipment allow a continuous monitoring of patients inside the hospital premises and are an extremely vital and inseparable part of hospital intensive care units and operating rooms, where critical care is needed and is based on patient readings.
The overall share held by hospitals in multi-parameter patient monitoring equipment is in a way being challenged by the home healthcare segment. This segment is witnessing a phenomenal rise in demand owing to the advantages it offers, such as reduced hospital visits and a significant reduction in medical expenses. This is a much-needed service for the patients suffering from chronic diseases, cardiac, and respiratory illnesses, whose numbers are currently growing at a very high rate.
The top manufacturers of multi-parameter patient monitoring equipment from a global standpoint include GE Healthcare, Philips Healthcare, Nihon Kohden Corporation, Drägerwerk AG & Co. KGaA, and Spacelabs Healthcare.
Minneapolis / St. Paul, Minnesota — Researchers at the University of Minnesota have made a major breakthrough that allows people to control a robotic arm using only their minds. The research has the potential to help millions of people who are paralyzed or have neurodegenerative diseases.
The study is published in Scientific Reports, a Nature research journal.
“This is the first time in the world that people can operate a robotic arm to reach and grasp objects in a complex 3D environment using only their thoughts without a brain implant,” said Bin He, a University of Minnesota biomedical engineering professor and lead researcher on the study. “Just by imagining moving their arms, they were able to move the robotic arm.”
The noninvasive technique, called electroencephalography (EEG) based brain-computer interface, records weak electrical activity of the subjects’ brain through a specialized, high-tech EEG cap fitted with 64 electrodes and converts the “thoughts” into action by advanced signal processing and machine learning.
Eight healthy human subjects completed the experimental sessions of the study wearing the EEG cap. Subjects gradually learned to imagine moving their own arms without actually moving them to control a robotic arm in 3D space. They started from learning to control a virtual cursor on computer screen and then learned to control a robotic arm to reach and grasp objects in fixed locations on a table. Eventually, they were able to move the robotic arm to reach and grasp objects in random locations on a table and move objects from the table to a three-layer shelf by only thinking about these movements.
All eight subjects could control a robotic arm to pick up objects in fixed locations with an average success rate above 80% and move objects from the table onto the shelf with an average success rate above 70%.
“This is exciting as all subjects accomplished the tasks using a completely noninvasive technique. We see a big potential for this research to help people who are paralyzed or have neurodegenerative diseases to become more independent without a need for surgical implants,” He said.
The researchers said the brain-computer interface technology works due to the geography of the motor cortex — the area of the cerebrum that governs movement. When humans move, or think about a movement, neurons in the motor cortex produce tiny electric currents. Thinking about a different movement activates a new assortment of neurons, a phenomenon confirmed by cross-validation using functional MRI in He’s previous study. Sorting out these assortments using advanced signal processing laid the groundwork for the brain-computer interface used by the University of Minnesota researchers, He said.
The robotic arm research builds upon He’s research published three years ago in which subjects were able to fly a small quadcopter using the noninvasive EEG technology. The research gained international media attention.
“Three years ago, we weren’t sure moving a more complex robotic arm to grasp and move objects using this brain-computer interface technology could even be achieved,” He said. “We’re happily surprised that it worked with a high success rate and in a group of people.”
He anticipates the next step of his research will be to further develop this brain-computer interface technology realizing a brain-controlled robotic prosthetic limb attached to a person’s body or examine how this technology could work with someone who has had a stroke or is paralyzed.
In addition to Professor He, who also serves as director of the University of Minnesota Institute for Engineering in Medicine, the research team includes biomedical engineering postdoctoral researcher Jianjun Meng (first author); biomedical engineering graduate student Bryan Baxter; Institute for Engineering in Medicine staff member Angeliki Bekyo; and biomedical engineering undergraduate students Shuying Zhang and Jaron Olsoe. The researchers are affiliated with the University of Minnesota College of Science and Engineering and the Medical School
The University of Minnesota study was funded by the National Science Foundation (NSF), the National Center for Complementary and Integrative Health, National Institute of Biomedical Imaging and Bioengineering, and National Institute of Neurological Disorders and Stroke of the National Institutes of Health (NIH), and the University of Minnesota’s MnDRIVE (Minnesota’s Discovery, Research and InnoVation Economy) Initiative funded by the Minnesota Legislature.
