Abstract

The embodiment of the present invention relates to the technical field of blood vessel puncture, and provides a method and device for auxiliary control of blood vessel puncture. Boundary data of the short-axis section of the blood vessel and position data of the center point of the blood vessel; the puncture path along the preset puncture angle direction based on the puncture target point is extracted, and according to the puncture path and the current position parameters of the puncture needle, the puncture needle is adjusted from the current posture to Required displacement parameters on the puncture path; based on the displacement parameters, the puncture needle is driven to move and adjust to the puncture path, and puncture the puncture target point along the puncture path. The vascular puncture auxiliary control method and device provided by the embodiments of the present invention can ensure that the needle tip of the puncture needle accurately reaches the puncture target point under the out-of-plane puncture technique, effectively avoiding the risk of complications in the out-of-plane puncture technique, and improving the success rate of one-time puncture .

Description

technical field [0001] Embodiments of the present invention relate to the technical field of blood vessel puncture, and in particular, to a method and device for auxiliary control of blood vessel puncture. Background technique [0002] Traditional vascular puncture uses an anatomical body surface positioning method for blind puncture, and the success rate of puncture mainly depends on the doctor's clinical experience. However, due to differences in patient constitution and imaging factors such as vascular anatomical variations, the body surface positioning blind puncture technique has a low success rate of one-time puncture and the risk of complications. With the popularization of ultrasound equipment, ultrasound-guided vascular puncture technology has gradually begun to be applied clinically due to the advantages of visible puncture process and high puncture success rate. Ultrasound-guided vascular puncture techniques are divided into in-plane and out-of-plane techniques a...
