Example Embodiment

[0022] Please also refer to figure 1 and figure 2 , which are device schematic diagrams respectively showing two different angles of a puncture needle positioning device according to an embodiment of the present invention. The puncture needle positioning device 100 of this embodiment can be directly worn by the patient, and the doctor can operate the puncture needle positioning device 100 to adjust and position the puncture needle 200, thereby preventing the patient from moving relative to the puncture needle positioning device 100, and further The needle insertion position and needle insertion angle of the puncture needle 200 are determined to achieve the purpose of improving the accuracy and success rate of the puncture operation.

[0023] Please continue to refer to figure 1 and figure 2 , the puncture needle positioning device 100 mainly includes a back frame 300 and a positioning mechanism 400 . In this embodiment, the back frame 300 is mainly worn on the human body...

Abstract

The invention discloses a puncture needle positioning device suitable for adjusting and positioning a puncture needle. The puncture needle positioning device comprises a back frame and a positioning mechanism, the positioning mechanism is arranged on the back frame and comprises a position adjusting structure and an angle adjusting structure, the positioning adjusting structure can move relative to the back frame in the first and second directions and comprises a first needle penetrating piece, the angle adjusting structure is arranged on the position adjusting structure, can move relative to the position adjusting structure and comprises a second needle penetrating piece, and the puncture needle can penetrate the second needle penetrating piece and the first needle penetrating piece. In this way, the step of positioning the puncture needle can be simplified through the puncture needle positioning device, and the positioning accuracy of the puncture needle can be substantially improved.

Description

technical field [0001] The invention relates to a positioning device, and in particular to a puncture needle positioning device. Background technique [0002] Percutaneous puncture surgery is a minimally invasive surgery, and doctors can apply it in, for example, lung tumor puncture, liver tumor puncture, percutaneous liver puncture biliary drainage, end-cancer pain blocking, etc. When performing percutaneous puncture surgery, doctors often use computed tomography (CT) to assist the doctor in judging the puncture position of the puncture needle. [0003] However, although doctors can judge the location of lesions through computerized tomography, in fact, when performing percutaneous puncture surgery, they need to rely on their own surgical experience, spatial geometry calculations, and hand feeling to complete the operation. Therefore, in the puncture process, if the doctor does not have enough experience, he must perform multiple computerized tomography and make multiple a...
