Picking device of inspection body for many biopsy

摘要

(57) Abstract In one configuration, this invention regards the instrument which picks the systematic inspection body from the region where the inside of the body is deep. The said instrument made the structure which can reach to the region alongside the long snaking path, long and narrow the basic destal and, it excises the systematic inspection body and the systematic inspection body which includes the polyp and the like and at the same time it has with the end which makes the structure which can remove the said systematic inspection body from the body. It pulls this revised dot, from the body and without pulling out it is the instrument which makes the structure which can pick the inspection body for many biopsy. The said instrument has the retractor of the systematic inspection body. The said retractor with systematic engagement position and the pulling included position which were expanded is operational in axial direction. When moving to pulling included position from expansion position, the open aisle where the retractor enters is provided. The said retractor engages in system, while moving to pulling included position from expansion position, has the terminal part which makes the structure which can grant the conveying power to axial direction to system. In order to be able to gather the consecutive inspection body inside the instrument, ahead and pulling included operation repeatedly the said retractor, have been designated as the kind of structure which can.
