Problems solved by technology

[0002] In the prior art, in the process of puncture interventional therapy, since the CT machine cannot dynamically observe the movement of the puncture needle in real time, doctors mostly rely on memory or compare static images to subjectively judge the puncture angle. Therefore, it is difficult to grasp the accuracy of the angle

Abstract

The invention discloses a puncture positioning device which comprises a guide rail and a puncture needle. The puncture needle is parallel to the guide rail, a clamping mechanism is slidably arranged on the guide rail and comprises a base and a cover plate, the cover plate covers the base, and a needle groove is formed in the top surface of the base along the length direction of the base in an embedded manner. The puncture positioning device has the advantages that needle penetration points, needle penetration angles and puncture distances can be determined by the aid of the puncture positioning device, accurate human interventional therapy can be carried out, errors due to the traditional experiential puncture can be prevented, accordingly, the surgical success rate can be increased, the surgical accuracy can be improved, and the puncture positioning device is convenient to use and high in efficiency and is safe.

Description

technical field [0001] The invention belongs to the technical field of medical device materials, and in particular relates to a puncture positioning device. Background technique [0002] In the prior art, during the puncture interventional treatment, since the CT machine cannot dynamically observe the movement of the puncture needle in real time, doctors mostly rely on memory or subjectively judge the puncture angle by comparing static images. Therefore, it is difficult to grasp the accuracy of the angle. Contents of the invention [0003] The purpose of the present invention is to provide a puncture positioning device, which can determine the needle entry point, needle entry angle and puncture distance, and perform precise interventional treatment on the human body, avoiding errors caused by traditional puncture based on experience, and improving the success rate and accuracy of the operation , Easy to use, safe and efficient. [0004] The present invention provides the ...
