During MIS procedures, as the surgeon's hands are remote from the site of the surgery, they do not have a feel of the tissue being manipulated and the forces that should be applied to manipulate the tissue. Studies are being conducted to provide tactile and force feedback of the tissues being manipulated to the surgeon. However, the surgeons are trained in conventional surgery and are familiar with the forces that they apply on the conventional surgical tools. Therefore, before such studies are conducted, there is a need for quantitative comparison of conventional and laparoscopic tools. The purpose of the present investigation was to determine if the forces applied on the conventional surgical forceps are the same as those applied on the laparoscopic forceps during the same procedures. The results of the study showed that the handle and tip forces in laparoscopic forceps were significantly different from that of the conventional surgical forceps (p ≤0.005). The results also showed that the mean power of the surface EMG measured from flexor pollicis brevis (flexor of the thumb) and the extensor pollicis brevis (extensor of the proximal thumb) while manipulating laparoscopic forceps were significantly different from that measured while manipulating conventional surgical forceps for the same procedure (p ≤ 0.005).","PeriodicalId":54588,"journal":{"name":"Presence-Teleoperators and Virtual Environments","volume":"1 1","pages":"218-228"},"PeriodicalIF":1.1,"publicationDate":"1997-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89968306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of 3D video endoscopic systems used in the operating theatre today is obviously lower than the number of established traditional 2D video endoscopic systems. The hesitant application of the new technology can be mainly explained by the lack of evaluation of its influence on the surgical procedure and on patient benefit as well as by the need for specific economic analysis. The starting point for our investigations was to analyze the influence of 3D video endoscopy on endoscopically guided manipulations in general. In order to achieve quantitative statements we performed laboratory experiments using human factors analyzing methods. In the next step we performed clinical field studies of the application of 3D video endoscopic systems for a side-by-side comparison of 2D and 3D systems. These studies showed that the use of 3D video endoscopy has an improving influence on endoscopically guided surgical manipulations as well as on the intraoperative procedures. We also found that spatial visual perception of stereoscopic images of 3D video systems may cause problems for some users. For the validation of stereoscopic visualization systems we additionally studied the influence of isolated technical, optical, and physiological parameters on visual perception as well as on transposition into visually guided manipulations. Detailed results of these investigations concerning the influence of 3D video endoscopy on binocular perception are presented.","PeriodicalId":54588,"journal":{"name":"Presence-Teleoperators and Virtual Environments","volume":"40 1","pages":"198-217"},"PeriodicalIF":1.1,"publicationDate":"1997-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85463138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was designed to compare three methods for training firefighters to navigate a rescue route in an unfamiliar building. Thirty firefighters from the Madison County, Alabama, area were trained to navigate through the Administrative Science Building at The University of Alabama in Huntsville. The firefighters, who had not had any experience with the Administrative Science Building prior to the experiment, were randomly assigned to one of three experimental training groups: Blueprint, Virtual Reality, or No Training (Control). After training, we measured the total navigation time and number of wrong turns exhibited by firefighters in the actual building. Participants were required to rescue a mock baby (a life-sized doll) following the specific trained route. Measures of test performance were compared among groups by using analyses of variance (ANOVAs). The results indicated that firefighters trained with virtual reality or blueprints performed a quicker and more accurate rescue than those without training. Furthermore, the speed and accuracy of rescue performance did not differ significantly between virtual reality and blueprint training groups. These results indicate that virtual reality training, if constructed and implemented properly, may provide an effective alternative to current navigation training methods. The results are discussed with regard to theories of transfer of training and human performance in virtual environments.","PeriodicalId":54588,"journal":{"name":"Presence-Teleoperators and Virtual Environments","volume":"28 1","pages":"73-86"},"PeriodicalIF":1.1,"publicationDate":"1997-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80825914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
