BACKGROUND AND OBJECTIVES Therapeutic laparoscopy was incorporated into surgical practice more than 25 y ago. Several modifications have since been developed to further minimize surgical trauma and improve results. Minilaparoscopy, performed with 2- to 3-mm instruments was introduced in the mid 1990s but failed to attain mainstream use, mostly because of the limitations of the early devices. Bu...

The principal objective was to measure the magnetic fields occurring in dental surgeries at simultaneous subtraction of direct ground component of the magnetic field. A specifically designed instrument with the Hall probe was used for the measurement. It consisted of two amplifiers and a low frequency filter. Its task was to measure mean square values of the field (RMS) dependent on the positio...

Results Clear explanations with diagrams and photos are used to illustrate the differences of the most commonly used surgical instruments. We demonstrate how this affects needle and tissue handling, as well as performance. Tips are also given for scrub nurses on handling and loading left-handed instruments. We recommend a standard set that will allow Cardiothoracic Units to provide the essentia...

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...
