3D Printed patient-specific surgical guide with a lateral hinge protecting K-wire and a soft tissue protecting sleeve for open wedge high tibial osteotomy: A pilot study

Open Wedge High Tibial Osteotomy (OWHTO) is an extensively used, effective treatment option for medical conditions such as medial knee osteoarthritis and varus malalignment. The current developments in the 3D printing industry facilitated using 3D printed patient-specific guides (PSSGs), making OWHTO a desirable treatment option. Although the...

Validation of a Novel Reusable Vacuum Extractor: a Comparative Mannequin Study between the Vela Vacuum Extractor and the Kiwi Omnicup

Abstract—Background: Vacuum extraction is a way to prevent unnecessary maternal deaths, by using a vacuum extractor to help deliver the baby in the second stage of labour. Vacuum extraction is still little-used in low- and middle-income countries (LMIC) compared to high-income countries, due to the lack of sufficient devices on the market that...

The development of an objective test method to evaluate the (optical) quality of rigid endoscopes at the CSSD

The quality of rigid endoscopes deteriorates during clinical use due to the sterilization process, mechanical forces and wear and tear during regular use. Regulations and standards on ensuring the quality of these instruments are currently non-existent or contain only qualitative measures, resulting in subjective examinations . Defective rigid...
