Embodiment Construction

[0020] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0021] refer to figure 1 and figure 2 A surgical path adjustment device under the guidance of ultrasound of the present invention is shown, the device includes: ultrasonic image processing and display terminal, linear movement structure and its measurement sensor, angle rotation structure and its measurement sensor, wireless ultrasonic probe, multi-stage Guide sleeve and ultrasonic terminal data acquisition and sending device.

[0022] Wherein the wireless ultrasonic probe (204) is fixed in the outer housing (201) of the device, and the relative positional relationship between the two remains unchanged. One end of the fixing splint (209) links to each other with the guide sleeve (208), and the other end is constrained in the chute on the device outer shell (201). The fixed splint (209) can move linearly in the chute along the X direction shown in th...

Abstract

The invention discloses an operation path adjusting device under ultrasonic guidance. The operation path adjusting device is characterized in that data collected by an ultrasonic mobile terminal of a displacement sensor and an angle sensor is utilized, an ultrasonic image processing and displaying terminal can calculate the relative position relation of a sleeve axis and an ultrasonic image in the plane, and the relation is displayed in real time in the ultrasonic image. According to the operation path adjusting device under the ultrasonic guidance, the ultrasonic image is relied on to achieve the guidance of the operation path of a puncture instrument, and the flexibility, safety and accuracy of an ultrasonic operation technique are improved.

Description

technical field [0001] The invention relates to the field of puncture surgery based on ultrasound image navigation, in particular to an operation path adjustment device guided by ultrasound. Background technique [0002] Ultrasound image-guided puncture is widely used in surgical fields such as tumor biopsy, drug injection, radiofrequency ablation therapy, and cryotherapy. This operation assists the tip of the puncture instrument to accurately reach the designated treatment area through the guidance and positioning of ultrasound images. Traditional puncture guidance methods can only be seen when the puncture instrument enters the plane of the ultrasound image, and cannot be planned in advance. Some new probes are equipped with a guide pin groove, which can calculate the angle of the guide pin by measuring the distance between the lesion and the skin surface before the puncture operation, but this device requires that the ultrasonic probe must be well fixed and cannot be disp...
