BACKGROUND Observational learning plays an important role in surgical skills training, following the traditional model of learning from expertise. Recent findings have, however, highlighted the benefit of observing not only expert performance but also error-strewn performance. The aim of this study was to determine which model (novice vs. expert) would lead to the greatest benefits when learnin...

Recent advances in endoscopic surgical techniques and the increased sophistication of surgical instruments have offered new operative methods and techniques for the gynecologic surgeon (1). Recent years have witnessed a marked increase in the number of gynecological endoscopic procedures performed, mainly as a result of technological improvements in instrumentation. The addition of a small vide...

Any laparoscopic surgery demands appropriate surgical instruments. Most surgeons nowadays have adapted to this different form of surgery and have particular preferences for certain types of graspers, dissectors and cutting instruments. The general component of laparoscopic instrument includes the hand grip, shaft, jaw and the tip. The harmonic scalpel is a surgical instrument used to simultaneo...

BACKGROUND When prearranged standard surgical trays contain instruments that are repeatedly unused, the redundancy can result in unnecessary health care costs. Our objective was to estimate potential savings by performing an economic evaluation comparing the cost of surgical trays with redundant instruments with surgical trays with reduced instruments ("reduced trays"). METHODS We performed a...

The breakthrough in biomedical and surgical instrument research follows the advances of newly developed biomedical technologies, improved composite materials, and renovated manufacturing methodologies. These new biomedical and surgical instruments allow physician to perform complex biomedical treatments and surgical operations with better medical quality. Some more complicated biomedical treatm...

At first glance, the highly technical procedures and specialization that characterize 21stcentury surgery bear little resemblance to the craft as practiced in Renaissance France and Italy or in the 19th-century operating theaters of Paris, London, or Philadelphia. Yet continuities in Western medical traditions link contemporary surgery to its professional predecessors. To understand the way sur...

Neurosurgeons have been trying to reduce surgical invasiveness by applying minimally invasive keyhole approaches. Therefore, this paper clarifies the detailed surgical technique, its limitations, proper indications, and contraindications for a superciliary keyhole approach as a minimally invasive modification of a pterional approach. Successful superciliary keyhole surgery for unruptured aneury...

Soon after the founding of the Microsurgical Instrumentation Research Association (MICRA) in 1971, it was decided to investigate the possible use of titanium and its alloys in the production of surgical instruments suitable for use with the microscope. After an analysis of surgical instruments available at that time, it was clear to us that modifications to existing designs were required. Most ...
