Problems solved by technology

However, the puncture is generally performed with the experience of the physician, or assisted by some simple imaging equipment, but it cannot accurately guide the advancement of the biopsy equipment. This not only requires extremely high experience of the attending doctor, but also has large errors. Accurately puncture the biopsy needle to the target sampling area, which increases the economic burden and treatment risk of patients

Embodiment 1

[0057] A method for single-needle or multiple-needle biopsy guided by laser, the specific steps are as follows:

[0058] S1. Fix the patient's body position, and obtain the image of the patient's pathological tissue through scanning;

[0059] S2. Determine the information of the pathological tissue according to the scanned image information, and determine the target sampling area;

[0060] S3. Import the confirmed target sampling area image into the processing system for modeling to obtain a target area model with a three-dimensional coordinate system;

[0061] S4. Import the target area model into the computer 3D treatment planning system for dimensional development, determine the biopsy route and puncture depth, and export the developed 3D data;

[0062] S5. Import the developed three-dimensional data into the laser emitting device, and adjust the laser emitting device to emit laser rays along the biopsy route;

[0063] S6. Adjust the puncture biopsy needle on the puncture...

Embodiment 2

[0066] As a preferred technical solution of the present invention, on the basis of embodiment 1, the specific steps of the step S2 are:

[0067] S201. Firstly, according to the scanned image of the patient's pathological tissue, confirm the volume, shape and position information data of the pathological tissue;

[0068] S202. Then confirm the important organs, bones, nerve vessels and adhesion with surrounding tissues around the pathological tissue, and determine the target sampling area according to the above information and the specific information of the pathological tissue;

[0069] S203. Then determine the model data of the target sampling area, and output the data for subsequent processing.

[0070] Through the scanned images, the basic information of pathological tissues can be determined, including the volume, shape and position information data of pathological tissues. Since important organs have a great influence on the vital signs of the human body, and the distribu...

Embodiment 3

[0072] As a preferred technical solution of the present invention, on the basis of Example 2, in the step S3, the modeling step is,

[0073] Step S301. Make a body surface marker point A0 on the target area of ​​the patient;

[0074] Step S302. Establish a three-dimensional coordinate system for the regional model. The three-dimensional coordinate system takes the body surface marker point A0 as the coordinate origin, takes the vertical line passing through the body surface marker point A0 as the z-axis, and determines x according to the coordinate origin and the z-axis axis and y-axis;

[0075] Step S303. Perform three-dimensional coordinate editing on the body surface contour, internal organ contour and pathological tissue in the patient's target area in the three-dimensional coordinate system;

[0076] Since the biopsy needle needs to enter the body through the body surface of the human body, it is necessary to determine a positioning point on the patient's body surface to...

Abstract

The invention belongs to the technical field of puncture biopsy and particularly relates to a method for performing single-needle or multi-needle puncture biopsy through laser guide. The method comprises steps as follows: S1, an image of pathological tissue of a patient is obtained through scanning; S2, information of the pathological tissue is determined according to the scanned image information, and a target sampling area is determined; S3, an image of the determined target sampling area is imported into a processing system for modelling, and a target area model with a 3D coordinate systemis obtained; S4, the target area model is imported into a 3D treatment plan system of a computer for dimension development, and a puncture biopsy route and a puncture depth are determined; S5, 3D dataobtained through development are imported into a laser emitting device, and the laser emitting device is adjusted to emit laser rays along the puncture biopsy route; S6, puncture biopsy needles on the puncture biopsy device are adjusted and inserted into the marked positions on a body surface of the patient to take out the pathological tissue. Through laser guide, the method is high in accuracy,short in the whole process cycle and high in flexibility.

Description

technical field [0001] The invention belongs to the technical field of puncture biopsy, and in particular relates to a single-needle or multi-needle puncture biopsy method guided by laser. Background technique [0002] The research on individualized diagnosis and treatment of tumors has entered the bottleneck stage, which requires the combination of new research ideas and directions. At present, molecular medicine and individualized treatment programs mainly use genomics (Genomics) and proteomics (Proteomics) to detect individual characteristics of tumors. The biggest limitation of this type of method is that it is necessary to extract part of the tumor tissue as a pathological test specimen through a needle biopsy. For diagnosis and treatment, the diseased tissue is removed from the patient's body by cutting, forceps or puncture, etc., for pathological examination. It is the most important part of diagnostic pathology. It can make a clear histopathological diagnosis for t...
