Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an ultrasound-guided nerve block puncture equipment. BACKGROUND

[0002] Ultrasound-guided nerve block puncture is a pain treatment method performed under the assistance of ultrasonic imaging. During treatment, according to the relationship between the puncture needle and the ultrasonic image, it can be divided into in-plane method and out-of-plane method. The in-plane method refers to that the needle insertion plane and the ultrasonic section are the same plane, and the ultrasonic image can display the entire needle body during needle insertion. The out-of-plane method refers to that the needle insertion plane and the ultrasonic section are perpendicular or at a large angle, and the ultrasonic image can only display the cross section of the needle body.

[0003] When the out-of-plane method is used for needle insertion, the use of isosceles right triangle is a common skill, as shown in FIG. 1. The depth L2 of the target 100 from the skin 300 is measured by the probe 200, and then the depth L2 is taken as the distance L1 between the needle insertion point 400 and the center of the probe 200. The puncture needle 500 is inserted at a 45° angle at the needle insertion point 400, and the probe remains stationary. When the puncture needle 500 appears, it is just located in the target.

[0004] Currently, the distance between the needle insertion point and the probe and the angle precision of the puncture needle when the out-of-plane method is used for needle insertion are limited by the experience of medical personnel. During the puncture process, the distance between the needle insertion point and the probe and the angle of the puncture needle are prone to deviation, so that the puncture needle cannot reach the target at one time, affecting the treatment effect and increasing the pain of the patient.

[0005] Therefore, it is necessary to design an ultrasound-guided nerve block puncture equipment capable of accurately controlling the distance between the needle insertion point and the probe and the angle of the puncture needle, ensuring the treatment effect and reducing unnecessary pain of the patient to solve the technical problems currently faced.
