RIGID ENDOSCOPE FOR PROSTATE BIOPSY AND TREATMENT INSTRUMENT

摘要

A rigid endoscope for prostate biopsy includes: an insertion portion including a distal end portion including an ultrasound transmission and reception portion, and a bent portion bent at a predetermined curvature; a treatment instrument insertion channel that passes through inside the bent portion and includes a first opening portion provided on a distal end side and a second opening portion provided on a proximal end side; a shaft-shaped portion installed to extend in a proximal end direction of the bent portion along a straight line passing through an inflection portion provided between the distal end portion and the bent portion; and a grasping portion that includes the shaft-shaped portion.

1. A rigid endoscope for prostate biopsy comprising:
an insertion portion that includes an ultrasound transmission and reception portion that transmits and receives ultrasound, a distal end portion including the ultrasound transmission and reception portion, and a bent portion which is provided on a proximal end side of the distal end portion and which is bent at a predetermined curvature; a treatment instrument insertion channel that passes through inside the bent portion and includes a first opening portion provided on a distal end side and a second opening portion provided on a proximal end side, the treatment instrument insertion channel being installed at a position that allows a treatment instrument protruding from the first opening portion to be housed within an observation range of the ultrasound transmission and reception portion; a shaft-shaped portion that is installed to extend in a proximal end direction of the bent portion along a straight line passing through an inflection portion provided between the distal end portion and the bent portion; and a grasping portion that includes the shaft-shaped portion.
