Title:
LESIONED SITE DETECTOR FOR CELIOTOMY AND LAPAROSCOPIC SURGERY
Document Type and Number:
WIPO Patent Application WO/1999/002098
Kind Code:
A1
Abstract:
A lesioned site detector for locating a lesioned site at the time of celiotomy or laparoscopic surgery. When a lesioned site of organs such as the stomach or the intestines is cut off by a surgical operation, it has been a practice in the past to endoscopically fit a clip to the site to detect the clip by feeling it from the outside at the time of surgery and to operate the site, or to inject a dye into the lesioned site at the time of inspection. These methods are not reliable and involve a safety problem. The detector of the invention detects by pinpointing a metallic clip or a magnetic clip fitted endoscopically at the time of inspection with a sensor disposed at the distal end portion, and can specify the detected site as the lesioned site. The detector has a shape suitable for celiotomy or laparoscopic surgery.
