Method for performing single-needle or multi-needle puncture biopsy through laser guide

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 a
