General information on the development of Minimally Invasive Surgery and MIS instruments is given. The \"MIS\" scientific study group was formed to discuss and find solutions for design and hygienic problems in MIS. The article describes various groups of MIS instruments, i.e. disposable instruments, instruments with a cleaning channel, and instruments which can be dismantled. Aspects of how the instruments can be processed effectively will be discussed in detail, including an example of a survey carried out in a German hospital with a special monitoring method. Requirements are described for MIS instrumentation with regard to design, material, and surface conditions. Requirements for hygienic processing methods are listed. The article also describes the necessary control and confirmation of cleanliness, which proves to be a very particular problem. Conclusions on the present status of technology and the possibilities for future development with regard to the processing of MIS-instrumentation are given.</p>","PeriodicalId":79337,"journal":{"name":"Endoscopic surgery and allied technologies","volume":"2 5","pages":"282-4"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18865841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since then vast experience has been gained in removing tumours of the rectum by the operative rectoscope. Though the indication in benign lesions for TEM as a local resection therapy is undisputed, the indication for resection of T1 or advanced carcinomas has to be evaluated. By using a 40 mm operating rectoscope sealed with a gastight working insert to prevent pressure loss after creation of a pneumorectum and a stereoscopic optic with sixfold magnification, exact visualisation of a rectal tumour can be achieved. The insertion of endoscopic surgical instruments like the high frequency knife, forceps, scissors, and suction device allows precise excision of the lesion as well as suture closure of the wound. Recently a bipolar multifunctional combination instrument has been developed for more precise dissection, less blood loss and shorter operation times.</p>","PeriodicalId":79337,"journal":{"name":"Endoscopic surgery and allied technologies","volume":"2 5","pages":"241-6"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18867293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New lasers in the IR-range of the optical spectrum appear on the market as pulsed lasers for tissue ablation searching for their specific fields of application. There is some confusion about laser applications at the moment until the new techniques and methods have proven to be really superior to other techniques.

These animals proved to be suitable for the instruments used in human laparoscopic procedures. It was planned to undertake a comparison between the waterjet and ultrasound dissectors, but this proved impossible because of the development of a thick intraabdominal mist during dissection with the waterjet dissector. The ultrasound dissector was effective in dissecting the intraparenchymal hepatic structures, especially the portal vein and the hepatic vein. These blood vessels were safely secured with endoclips, while bleeding points on the resection surface were coagulated with an argon beam coagulator. The liver specimens removed were approximately 75 g in weight. All ultrasound-dissected animals survived for 10 days.
