Microbial tightness of O-ring seals. Case study: duodenoscopes: Evaluation of the sealing efficiency against bacteria of the distal O-ring seal of the Olympus TJF-Q180V duodenoscope

Sealing constructions are frequently used in reusable instruments to prevent the loss of fluids or gasses in a construction by obstructing flow through the glands in the interface of two or more separate parts, and may be applied to seal patients' body fluids. Patient material contains various types of microorganisms, and with the increase of...

Improvement of patient-specific resection templates in mandible reconstruction using a fibula graft

To recover a mandible defect, the defect is resected and the resulting bone gap can be reconstructed by a fibula graft that shaped similar to the resected part of the mandible. Mandible resection and shaping of the fibula bone is assisted by computer-aided simulation and computer-aided manufacturing (CAS/CAM). In a nutshell, these techniques...
