Problems solved by technology

[0004] However, in-plane freehand puncture requires that the needle path is completely in the ultrasonic scanning plane during puncture, and the needle path cannot be displayed if it is slightly deflected. The doctor needs to constantly adjust the position of the puncture needle to better display the needle path. Bring many problems and affect the quality of puncture to a certain extent

Embodiment Construction

[0029] A very important issue in freehand puncture is to maintain the accuracy of the needle path and to select a suitable puncture point, but these are inseparable from the support of imaging equipment. When B-ultrasound and color Doppler ultrasound are used for exploration before puncture, the ultrasonic probe will eventually reach the target position to be punctured during the movement process. At this time, the doctor needs to determine the puncture position and needle angle by looking at the monitor. However, due to the lack of a good force point during the freehand puncture process, even with the guidance of the detected image, the needle path will still deviate; while the ultrasound equipment detection image is only a limited fan-shaped surface on the display, and the needle path is slightly deviated The needle is no longer visible and needs to be corrected or repunctured.

[0030] The idea proposed by the inventor in this solution is that most of the reasons for the de...

Abstract

The invention discloses an ultrasound-guided puncture positioning guide device. The ultrasound-guided puncture positioning guide device comprises a guide device body for installing a positioning plate on an ultrasonic probe, a first sliding groove with scales is arranged on the positioning plate, and a needle sleeve is assembled in the sliding groove; and the ultrasonic probe is detachably installed on the positioning plate. According to the ultrasound-guided puncture positioning guide device, an auxiliary laser positioning device is adopted, after the ultrasound position is determined, the scope where a puncture needle way can be built is determined through the laser positioning device, the position of the needle way can be displayed through a display screen all the time, and therefore the good auxiliary effect is provided for a doctor; a positioning plate structure matched with the probe is arranged so as to be capable of being matched with an ultrasound imaging device, under indication of puncture target spots displayed in the display screen of the ultrasound imaging device, the puncture position is precisely given through the scales on the positioning plate, and the puncture process can be implemented with a purpose; and the overall set of device can be applied to multiple positions on the body surface and can have the fixing effect on the ultrasonic probe, so that the overall puncture process is premise and simple, and the good puncture effect is achieved.

Description

technical field [0001] The invention relates to a device for assisting puncture, in particular to a puncture positioning guide under imaging equipment. Background technique [0002] In recent years, with the improvement of the performance of ultrasound instruments, the improvement of puncture needles and the accumulation of experience of operating doctors, ultrasound-guided puncture has become a very important diagnostic technique, enabling many diseases, especially tumor diseases, to be diagnosed in a timely and clear manner. It provides the most important information for the selection of treatment methods, the selection of surgical methods, and the evaluation and follow-up during and after treatment. [0003] Ultrasound-guided puncture technology has the characteristics of flexibility, convenience, and small blind area, and is suitable for various superficial lesions such as biopsy, arterial and venous puncture, and nerve block. The specific method is to avoid important o...
