  • Publication number: 20240050060
    Abstract: An ultrasonic diagnostic apparatus that assists an insertion task of a puncture needle into a subject, includes: an ultrasonic probe that acquires an ultrasonic image of an inside of the subject by transmitting and receiving ultrasonic waves; a first capture part and a second capture part that are attached to the ultrasonic probe and capture the puncture needle at the insertion task; and a hardware processor that performs image analysis on a first captured image generated by the first capture part and a second captured image generated by the second capture part, and detects an insertion angle of the puncture needle relative to a body surface of the subject using a stereo camera principle, calculates a predicted arrival position of the puncture needle from the insertion angle, and displays a guide image indicating the predicted arrival position on a monitor so as to be superimposed on the ultrasonic image.

  • Publication number: 20230263575
    Abstract: An ultrasonic diagnostic apparatus for assisting insertion of a puncture needle into a subject, includes: an ultrasonic probe that is arranged to allow a probe distal end part to be pressed against a body surface of the subject, and acquires an ultrasonic image of an inside of the subject by transmission and reception of an ultrasonic wave; an optical camera that is attached to a proximal end side of the probe and captures an image of an arrangement position of the probe distal end part of the probe on a body surface; and a laser pointer that is attached to a proximal end side of the probe and emits laser light onto a body surface to form a predetermined projection image, to guide a target insertion position and a target orientation of the needle when the needle is inserted into the subject, in an optical image acquired by the camera.

  • Publication number: 20180263599
    Abstract: An ultrasonic probe includes: a support base; a rotation body which rotates while being supported by the support base; an ultrasonic oscillator which is disposed on an outer peripheral surface of the rotation body; and a rotary electric connector which is disposed to axially support the rotation body by the support base and exchanges electric signals with the ultrasonic oscillator, wherein the rotary electric connector includes: a rotary electrode which is bonded to the rotation body and rotates along with the rotation body, a fixed electrode which is bonded to the support base to face the rotary electrode and forms an annular guide groove in a rotation axis rotation in a region facing the rotary electrode, and a rotary contact member that is disposed inside the guide groove and rolls along the guide groove while contacting both the rotary electrode and the fixed electrode.
