Abstract

The present invention relates to an out-of-plane ultrasonic guiding device. The out-of-plane ultrasonic guiding device comprises a telescopic arm, a fixed end of the telescopic arm is provided with arotating sleeve, an axial center line of the rotating sleeve is superposed with a central axis of an ultrasonic probe, and a transverse axis of the telescopic arm is vertical to the central axis; an telescopic end of the telescopic arm is provided with a rotating mechanism, the rotating mechanism is provided with a telescopic positioning sleeve and a microcomputer, an ultrasonic machine measures avertical distance between an intersection point of the central axis and the skin and a puncture end point, the positioning sleeve measures a vertical length between a puncture starting point and thetransverse axis, the microcomputer calculates rotating angles of the rotating mechanism according to vertical distance, vertical length and horizontal distance data, and the rotating mechanism drivesthe axis of the positioning sleeve to rotate to coincide with a straight line determined by the puncture starting point and the puncture end point according to the rotating angles. Through the telescopic arm, rotating mechanism, telescopic positioning sleeve, and microcomputer the device can realize rotation of the positioning sleeve of a positioning puncture needle, and thus can accurately position the puncture angles of the puncture needle out of a plane.

Description

technical field [0001] The invention relates to a puncture positioning device, in particular to an out-of-plane ultrasonic guiding device. Background technique [0002] In ultrasound-guided puncture, according to the relative position of the puncture needle and the ultrasound probe, it can be divided into ultrasonic in-plane puncture (the puncture needle is located in the imaging plane of the ultrasound probe) and ultrasonic out-of-plane puncture (the puncture needle is in the imaging plane of the ultrasound probe). out of plane). Compared with ultrasonic out-of-plane puncture, ultrasonic in-plane puncture can fully display the path of needle insertion and the position of needle tip, so it is widely used. For ultrasound in-plane puncture, since the puncture needle can only be visualized on the ultrasound screen and reach the target site when it moves within the imaging plane of the ultrasound probe, it is necessary to strictly control the insertion point and direction of th...
