Ultrasound inspection apparatus detachably connected to endoscope
First Claim
1. An ultrasound inspection apparatus detachably connected to an endoscope, said ultrasound inspection apparatus comprising:
- an ultrasonic scanning portion having an ultrasound transducer attached thereto in the front end side for performing ultrasonic scanning by arranging transducer chips in an array arrangement;
an endoscope-placing portion disposed at a base side position of said ultrasonic scanning portion to be detachably mounted onto an outer periphery of a distal end portion of an insertion unit of an endoscope;
an endoscope-fixing portion for detachably fixing said distal end portion placed on said endoscope-placing portion; and
a signal cable formed of a predetermined number of wires connected to said ultrasound transducer from the base end position of said endoscope-placing portion and extending along the exterior of said insertion unit.

Abstract
An ultrasound inspection apparatus detachably connected to an endoscope comprises an ultrasonic scanning portion in the front-end side having an ultrasound transducer for performing ultrasonic scanning by arranging a number of transducer chips in a rectangular arrangement. The ultrasonic scanning portion is detachably attached to a distal end portion of an insertion unit in the endoscope so as to protrude ahead the distal end portion by a predetermined length. In order to hold the ultrasonic scanning portion in a fixed state, an endoscope-placing portion for placing the distal end portion is connected to the base end of the ultrasonic scanning portion, and an endoscope-fixing portion for detachably fixing the distal end portion thereto is arranged with the endoscope-placing portion. A predetermined number of wires connected to each transducer chip is inserted into a signal cable from a base end position of the endoscope-placing portion so as to bundle the wires.
