CT and nuclear magnetic resonance assisted positioning identification point device and use method thereof

Abstract

The invention relates to the technical field of medical auxiliary equipment, and provides a CT and nuclear magnetic resonance assisted positioning mark point device and a use method thereof. The CT and nuclear magnetic resonance assisted positioning mark point device comprises a shell with openings formed in the upper portion and the lower portion and a mounting portion, the shell is mounted on the surface of a human body through the mounting portion, and at least two light source collecting layers and a control center are arranged in the shell; each light source collection layer comprises a plurality of light source emitters and light source receivers which are arranged in a one-to-one correspondence mode, the light source receivers and the light source emitters are arranged on the two sides of the opening, the output ends of the light source receivers are connected with the input end and the output end of the control center, light paths in the adjacent light source collection layers form an angle alpha, and alpha is larger than 0 degree and smaller than 90 degrees; the multiple light source collection layers distributed at a certain angle are arranged to assist in positioning the puncture needle, and positioning is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a CT and nuclear magnetic resonance auxiliary positioning mark point device and a method for using the same. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. Angiography, etc. The process of puncture surgery is roughly as follows: the doctor designs a puncture path plan based on CT and other imaging results; the puncture path plan includes determining the puncture position, puncture angle, etc., and then performs the puncture surgery. [0003] In the puncture operation, the puncture position can be positioned by setting a mark. The puncture angle is mainly completed through cooperation between two doctors...

AI Technical Summary

Problems solved by technology

This method makes the puncture angle inaccurate, which may damage the tissues around the lesion due to the inaccurate puncture angle, and may also require multiple punctures to adjust, thus prolonging the operation time

[0004] In addition, in some operations, it is necessary to perform a second puncture sampling or injection on the target tissue. In the process of the second puncture, if the puncture is repositioned, it will cause two puncture errors. Therefore, how to accurately perform the second puncture Positioning is very necessary
