Histological and cytological biopsies are the "gold standard" recognized in the medical community as the basis for clinical pathology diagnosis. Needle biopsy is the primary way to obtain a pathological diagnosis. At present, the cutting principle of the percutaneous biopsy needle product used clinically mainly comprises two types of side cutting and end cutting.
Wherein, the working process of end cutting is as follows: when the puncture biopsy is carried out, a biopsy needle is loaded, then the percutaneous puncture is carried out under the guidance of an image, and the biopsy needle is inserted to the edge of a target tissue. When the material is taken, the middle needle tube is quickly fired to penetrate into the target tissue, the tissue with the preset length is cut off and stored in the middle needle tube, the outer needle tube is also fired to the front after the middle needle tube, and the section on the outer needle tube cuts off the tissue sample. Subsequently, the biopsy needle is withdrawn from the target tissue, loaded into the biopsy needle, and the inner needle ejects the specimen in the middle needle tube. During the operation of the end cutting, the sampling operation of the target tissue is realized by adopting a biopsy needle ejection mode. The biopsy needle is ejected forwards after being fired, the prediction of the needle point range needs to be carried out, and when the target tissue is positioned at the edge of an organ, the risk of the firing process is higher.
