Description

Technical Field

[0001] The utility model relates to a disposable ultrasonic-guided puncture needle device, belonging to the technical field of ultrasonic puncture. Background Art

[0002] Ultrasound-guided puncture is a medical procedure performed under real-time ultrasound guidance, mainly used to obtain diseased tissue samples or perform other therapeutic operations. The following is a detailed explanation of ultrasound-guided puncture: 1. Definition and principle. Ultrasound-guided puncture refers to the accurate puncture of a dedicated puncture needle or catheter into the target area (such as lesions, fluid cavity, etc.) under the real-time guidance of ultrasound imaging technology to obtain diseased tissue samples, drain fluid or perform other therapeutic operations. Ultrasound imaging technology can clearly display the size, shape, position of the lesion and important structures along the puncture path (such as large blood vessels, nerves, surrounding organs, etc.), thereby ensuring the accuracy and safety of the puncture.

[0003] Authorization announcement number (CN213283251U); A multi-angle puncture guide needle device includes a frame and an angle adjustment seat, the angle adjustment seat is rotatably connected to the frame at one end close to the sound head of the ultrasound probe, and multi-angle adjustment is achieved at the other opposite end through a matching rotation angle limit structure, the frame is provided with a first rotation mating surface on the front and / or rear side of the ultrasound probe wrapped in a direction perpendicular to the ultrasound image plane, and a mounting arm extends from the corresponding front and / or rear side of the angle adjustment seat, and the mounting arm is provided with a second rotation mating surface that rotatably cooperates with the first rotation mating surface to achieve a rotational connection between the angle adjustment seat and the frame, and the rotation center of the first rotation mating surface and the second rotation mating surface is located on the inner side of the outer contour of the ultrasound probe in the direction perpendicular to the ultrasound image plane above the skin contact extension surface of the sound head of the ultrasound probe.
