  • Device for examining a subject capable of marking a boundary range for insertion/retraction of an insertion/retraction member that is inserted in and retracted from the subject
    Patent number: 6786870
    Abstract: An ultrasound diagnostic device comprises an ultrasound endoscope, an ultrasound diagnostic signal processing device and a monitor and is arranged to obtain an ultrasound diagnostic image by performing transmission/reception of ultrasound signals with respect to a detection subject within a body cavity. The ultrasound endoscope comprises an insertion section inserted into a body cavity, an operating section and a connecting cord. A biopsy needle insertion/retraction section is employed for forward or backward insertion/retraction of a biopsy needle. The subject may be pierced by the needle tip of a biopsy needle that protrudes from a biopsy needle protrusion port at the tip of an insertion section of the ultrasound endoscope which has been inserted. The monitor displays the biopsy needle in the ultrasound diagnostic image.
