We propose a method for accurately tracking the spatial motion of standard laparoscopic instruments from video. By exploiting the geometric and photometric invariants common to standard FLS training boxes, the method provides robust and accurate tracking of instruments from video. The proposed method requires no modifications to the standard FLS training box, camera or instruments.

Single-port laparoscopic technology is effective in minimally invasive surgery. However, this technology requires expensive instrumentation. In the present study, an alternative minimally invasive technique, periumbilical laparoscopic surgery through triple channels using common instrumentation, is introduced. Increased use of this new technique may be worthwhile since its results are comparabl...

Solid pseudopapillary neoplasm (SPN) is a rare tumor of the pancreas. Laparoscopic distal pancreatectomy (DP) is a feasible and safe procedure, and successful spleen preservation rates are higher using a laparoscopic approach. We hypothesized that certain patients with SPN would be good candidates for laparoscopic surgery; however, few surgeons have reported laparoscopic DP for SPN. We discuss ...

In the last ten years, the single incision laparoscopic surgery (SILS) is gaining more interest than the traditional laparoscopic surgery (LAP). Many studies make a comparison between the performances of the SILS and the LAP. The results show that the single incision laparoscopic surgery reduces pain, length of period of postoperative hospitalization, and loss of blood. This technique is also a...

Endoscopic surgery routinely produces video data. Automated understanding of these data has applications both online (visual servoing for telemanipulation) and offline (procedure analysis, annotation and content-based retrieval). As a step towards such applications, a method for tracking surgical instruments in endoscopic video without modifications to instruments or endoscopic equipment is des...

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...

Surgical techniques rely heavily on adequate visualization of target anatomy. Particularly in laparoscopic and robotic laparoscopic surgery, the operative anatomy and the general view of the operative field is removed from the surgeon’s direct vision. Manipulation of peripheral anatomy (i.e. retraction) may lead to ischemia, infarction, and mechanical disruption. The primary goal of our researc...

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...
