Abstract

The invention includes: an ultrasound transducer; a holding part that holds the ultrasound transducer; an insertion portion in a rigid cylindrical shape where the holding part is installed at a distal end; and an insertion assisting instrument in a rigid rod or cylindrical shape-disposed in an extractable manner in the insertion portion; wherein: the holding part is installed at the distal end of the insertion portion to form a shape that is curved with a predetermined angle in a separating direction from a longitudinal direction from the distal end of the insertion portion; and a curvature angle of the holding part to the longitudinal direction of the insertion portion is set so that, when the insertion assisting instrument is inserted in the insertion portion, a straight line that contacts a distal end face of the insertion assisting instrument contacts the ultrasound transmitting / receiving face.

Description

technical field [0001] The invention relates to an ultrasonic observation device which can be inserted through the urethra. Background technique [0002] In recent years, the number of patients with prostate cancer tends to increase. In the past, transrectal biopsy under ultrasound observation was the mainstream method for diagnosing prostate cancer. [0003] Generally, during needle biopsy, the longer the puncture path in the tumor tissue, the more tumor cells are collected, so the probability of confirming the tumor cells is higher. Thus, it is desirable to take longer piercing paths. [0004] In addition, prostate cancer tends to frequently occur in the peripheral portion of the prostate. However, in transrectal biopsy, there is a tendency that the part passing the prostate margin in the puncture path becomes shorter. Therefore, there is a limit to improving the probability of finding tumor cells of prostate cancer by transrectal biopsy. [0005] Therefore, transuret...
