Problems solved by technology

However, the squeezed state of blood vessels cannot be clearly grasped only by visually observing the ultrasonic images, and it is difficult to judge whether the pressing state of the ultrasonic probe at the current time point is the best state for the patient to facilitate blood vessel puncture

no. 1 approach

[0016] figure 1 A schematic configuration diagram showing the puncture support system according to the first embodiment. In the figure, the puncture support system 10 according to this embodiment is a system for providing puncture support information to a doctor when the doctor performs blood vessel puncture under the guidance of ultrasound. The puncture support information is information for supporting the puncture.

[0017] This puncture support system 10 includes: an ultrasonic diagnostic device 11 for acquiring an ultrasonic image of an internal body part including a blood vessel B of a patient to be punctured; The ultrasonic image of B generates puncture support information.

[0018] The ultrasonic diagnostic apparatus 11 includes: an ultrasonic probe 15 that contacts the patient's skin S to transmit ultrasonic pulses and receives echoes; The ultrasonic image of the lower body part; the blood vessel diameter detection unit 18, based on the image data of the ultrasonic i...

[0032] Such as figure 2 As shown, the puncture assisting system 30 according to this embodiment is characterized in that, compared with the configuration of the first embodiment, it includes a function of operating the puncture needle N in the blood vessel B based on the ultrasonic image acquired by the ultrasonic diagnostic device 11 . The puncture support robot 33 that punctures the patient's target can use the puncture support robot 33 to control the pressing state of the ultrasonic probe 15 into the patient's skin S based on the puncture support information, so that the position and posture of the ultrasonic probe 15 can be maintained. For ease of piercing.

[0033]The puncture assisting robot 33 is a hand-held robot that holds the ultrasonic probe 15 and the puncture needle N respectively, and the doctor can manually move the ultrasonic probe 15 in order to obtain an ultrasonic image, or can automatically move the ultrasonic probe 15 to obtain an ultrasonic image. Adjus...

Abstract

The purpose of the present invention is to provide information pertaining to a collapsed state of a blood vessel intended to be punctured, such collapse caused by the pressing of an ultrasonic probe when acquiring ultrasonic images of the blood vessel. A puncture assistance system 10 is provided with: a vascular diameter detecting means 18 for detecting a vascular diameter during acquisition of ultrasonic images from an ultrasonic diagnostic device 11; a puncture assistance information generating means 12 that generates puncture assistance information for determining whether puncturing is possible on the basis of the collapsed state of a blood vessel B due to pressing of an ultrasonic probe 15 against the skin S, such generation performed by comparing a current vascular diameter detected by the vascular diameter detecting means 18 and a pre-stored reference vascular diameter; and a monitor 19 for presenting the puncture assistance information. As the puncture assistance information, the following are found: a vascular compression rate representative of the ratio of the vascular diameter during ultrasonic image acquisition relative to the pre-stored reference vascular diameter; and a puncture feasibility rate representative of the current ease of puncturing at the blood vessel B due to the pressing of the ultrasonic probe 15.

Description

technical field [0001] The present invention relates to a system for assisting ultrasound-guided vascular puncture. Background technique [0002] The puncture of the patient's internal tissue is used in various medical scenarios, among which is the vascular puncture under the guidance of ultrasound. In this blood vessel puncture, the doctor searches for a desired blood vessel position on the ultrasound image while visually observing the ultrasound image of the patient's blood vessel cross-section obtained by an ultrasonic diagnostic device, and places the tip of the puncture needle in the blood vessel. At this time, in order to obtain the ultrasonic image of the blood vessel, the skin above it is pressed to a certain extent by the ultrasonic probe. . Therefore, in order to facilitate the puncture of the blood vessel, the doctor must adjust the pressing force of the ultrasonic probe so that the squeezed state of the blood vessel is maintained within an appropriate range, an...
