Problems solved by technology

At present, most of the puncture needle positioning devices used in ultrasonic in-plane puncture only consider the needle entry point, and are not accurate to the puncture angle, puncture length, etc., and the puncture may not be accurate enough, resulting in multiple punctures and unnecessary tissue damage. , increasing the pain of the patient

Embodiment Construction

[0014] Combine below figure 1 and figure 2 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0015] The present invention provides a puncture positioning device in an ultrasonic plane, comprising a telescopic arm 1 that can be stretched laterally, and a clamp 2 for clamping an ultrasonic probe 6 of an ultrasonic machine is provided at the fixed end of the telescopic arm, so that the ultrasonic probe and the clamp are not separated. Relative movement occurs, and the use of clamps is also convenient for disassembly, which is beneficial to ordinary ultrasonic puncture. The axial centerline of the hoop coincides with the central axis of the ultrasonic probe, the transverse axis of the telescopic arm is perpendicular to the central axis, so that the telescopic arm is perpendicular to the ultrasonic probe; the telescopic...

Abstract

The invention relates to an ultrasonic in-plane puncture positioning device. The ultrasonic in-plane puncture positioning device comprises a telescopic arm, the fixed end of the telescopic arm is provided with a clamp, an axial center line of the clamp coincides with a central axis of an ultrasonic probe, and a transverse axis of the telescopic arm is perpendicular to the central axis; the telescopic end of the telescopic arm is provided with a rotating mechanism, the rotating mechanism is provided with a positioning piece, and the rotating mechanism drives an axis of the positioning piece torotate in a plane determined by the transverse axis and the central axis; a micro-calculator is arranged, an ultrasonic machine measures the vertical distance between an intersection point of the central axis and the skin and a puncture endpoint, the micro-calculator calculates the rotation angle of the rotating mechanism according to input data about the vertical distance and data about the horizontal distance between the intersection point and a puncture starting point, and the rotating mechanism drives the positioning piece to coincide with a straight line determined by the puncture starting point and the puncture endpoint. According to the ultrasonic in-plane puncture positioning device, through the telescopic arm, the rotating mechanism, the micro-calculator and the like, rotation ofthe positioning piece for positioning a puncture needle can be achieved, and thus the puncture angle of the puncture needle is precisely positioned.

Description

technical field [0001] The invention relates to a puncture positioning instrument, in particular to an ultrasonic in-plane puncture positioning 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 di...
