Problems solved by technology

[0005] The purpose of the present invention is to provide a positioning and guiding device for CT or nuclear magnetic resonance puncture to solve the problem that the fixation effect of puncture needs to be improved in the existing puncture process proposed in the above-mentioned background technology. In the case of the first acquisition, it is difficult to ensure the stability of the puncture position, which leads to deviations in the lesion sampling process, which directly affects the effectiveness of the detection, and there is no effective guidance after fixation, and the puncture position is not discernible. There will be errors in puncture, and the problem that it cannot effectively play a positive guiding role

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] The invention provides a positioning and guiding device for CT or nuclear magnetic resonance puncture. Through the combined use of accessories, the puncture positioning effect can be improved, and the transmitted position can be digitally distinguished, which is convenient for secondary puncture after recording, and has strong guidance. Please refer to Figure 1-5 , including a main board 100, a lower strip 200, a positioning plate 300, a main flap 400 ...

Abstract

The invention belongs to the technical field of puncture devices, and particularly relates to a positioning and guiding device for CT or nuclear magnetic resonance puncture. The device comprises a main plate, a lower strip plate, a positioning plate, a main turning plate and a main buckle, and a puncture cavity is integrally formed in the top of the main plate; the top and the bottom of the puncture cavity are integrally connected with an upper strip plate and the lower strip plate respectively. According to the positioning and guiding device for CT or nuclear magnetic resonance puncture, themain turning plate and an auxiliary turning plate which are provided with suction cups and arranged on the main plate are used for adsorbing the puncture position, the main buckle and an auxiliary buckle which are provided with binding bands and binding ropes are also used for further fixing, after the puncture position is determined, a positioning plate is moved through an upper sliding block anda lower sliding block, the upper sliding block is fixed through a limiting nail after determination, and the puncture position is digitally recorded; a plurality of sets of positioning holes are formed in the positioning plate, the matching performance is high in the puncture cooperation process, a perforated position can be fixed through a diaphragm additionally arranged inside, and a puncture needle is prevented from shaking.

Description

technical field [0001] The invention relates to the technical field of puncture devices, in particular to a positioning and guiding device for CT or nuclear magnetic resonance puncture. Background technique [0002] In the treatment of modern medicine, for malignant tumors, whether there is a mutation in its pathological classification, typing or even genetic testing is the primary issue in the process of disease diagnosis and treatment. The diagnosis results directly determine the use and efficacy of anti-tumor drugs, and become It is an indispensable step in the process of disease diagnosis and treatment. [0003] Among them, in the process of diagnosis and treatment, CT and MRI will be used together. The principles of CT and MRI are different. MRI has a higher resolution for soft tissues, and CT has a higher diagnostic rate for bones. CT and MRI are both useful for checking diseases. There are places that complement each other, but using the CT scan image as a guide refe...
