TECHNICAL FIELD

[0001] The utility model relates to medical field, concretely is a kind of ultrasonic guiding in-plane puncture auxiliary support. BACKGROUND

[0002] Ultrasound-guided puncture includes vascular puncture, nerve block, pain management, biopsy puncture, interventional therapy and so on, and its in-plane, out-of-plane puncture technology is more and more widely used as two basic technologies.

[0003] Among them, in-plane puncture refers to the process that puncture needle as a whole is in the sound beam emitted by ultrasound under the guidance of ultrasound, and the specific method is as follows:

[0004] When short-axis scanning is carried out by ultrasonic probe, the target area is fixed to the middle of ultrasonic field (the middle of left and right), the position of probe is fixed, the probe is rotated by 90 degrees, the scanning target is changed from short axis to long axis, the puncture needle enters subcutaneous tissue at a certain angle (the specific angle depends on the distance between puncture target and needle entry point) along the center line of both ends of probe, and the puncture needle is observed to enter blood vessel or stop advancing near target area.

[0005] In this process, since ultrasonic probe and syringe are independent structures, the operator needs to control probe and syringe simultaneously when puncturing, and high coordination ability is required for probe and syringe, actual operation is difficult, and puncture error is easy to occur.
