Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic puncture, in particular to an ultrasonic guided puncture device. Background Art

[0002] In the field of modern medical technology, ultrasound-guided puncture devices, as an important diagnostic and treatment tool, play an increasingly critical role. Ultrasound technology is widely used in clinical diagnosis and treatment due to its advantages such as being non-invasive, real-time, and repeatable.

[0003] However, it is difficult for traditional ultrasound-guided puncture devices to automatically adjust the adsorption angle of the adsorption head according to the curvature of the human body surface. The human body surface is not completely flat, and there are various curvatures and curves. Since traditional devices lack the ability to automatically adjust the adsorption angle, when encountering complex curved surfaces on the human body surface, the adsorption head often cannot fit the human body well, resulting in loose adsorption, which not only affects the stability of the device, but also may affect the accuracy of the puncture due to the movement of the device during the puncture process. Secondly, in the ultrasound image, the display of the puncture needle is sometimes not clear enough, especially when the angle between the puncture needle and the ultrasound beam is not perpendicular, the needle shadow may be unclear or disappear, increasing the puncture. Secondly, when performing ultrasonic puncture, the traditional ultrasound-guided puncture device fixes the ultrasonic detection head and makes it difficult to adjust the contact force between the detection head and the human body surface according to real-time needs. In actual operation, different patients, different puncture sites and different conditions may require different contact forces. If the contact force is too large, it may cause discomfort to the patient or even cause tissue damage. If the contact force is too small, a clear ultrasound image may not be obtained, affecting the doctor's accurate judgment of the puncture target. Since the traditional device cannot flexibly adjust the contact force, the doctor is greatly restricted during the operation and it is difficult to perform the best puncture operation according to the specific situation.
