Abstract Background Moistening of surgical instruments affects the quality instrument cleaning, thereby affecting degree cross-contamination and in-hospital infection among patients. Surgical should be kept moist immediately after use in order to avoid concentrations contamination remaining on surfaces. Implementation pass rates moistening have been rarely studied. We aimed investigate factors ...

Real-time three-dimensional ultrasound enables new intra-cardiac surgical procedures, but the distorted appearance of instruments in ultrasound poses a challenge to surgeons. This paper presents a detection technique that identifies the position of the instrument within the ultrasound volume. The algorithm uses a modified Radon transform to search for long straight objects in the ultrasound ima...

Modern surgical procedures involve flexible instruments for both diagnostic and therapeutic purposes. The implementation of flexible instruments in surgery necessitates high motion and force fidelity, and good controllability of the tip. However, the positional accuracy and the force transmission of these instruments are jeopardized by the friction and clearance inside the endoscope, and the co...

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...
