Bone and soft tissue tumors are diseases seriously harming human health and life, the incidence rate gradually rises in recent years, the onset age gradually declines, and early detection, correct diagnosis and timely treatment have important influence on the future. With the continuous improvement of examination means and methods, the diagnosis accuracy is gradually improved, but a large part of tumors still have no typical imaging characteristics and are difficult to diagnose. The correct diagnosis requires three combinations of clinical, imaging and pathology. Among them, pathological diagnosis plays a key role in the selection of a treatment regimen. In clinical application, the B-ultrasonic can clearly display various sectional images of organs and peripheral organs, and the images are rich in solid body sense and close to the real anatomical structure, so that the early clear diagnosis can be realized by applying the ultrasonic.

Needle biopsy is the main approach to obtain pathological diagnosis in conjunction with B-ultrasound examination. As the limb protection treatment of malignant tumor has become a main trend, the requirement of biopsy has more strict requirements on the access and method of material collection. Incorrect biopsy often causes contamination of local important structures such as blood vessels and nerve bundles by tumors during material drawing, so that the tumors cannot be completely excised, and the limb protection treatment fails. Therefore, prior to needle biopsy, the nature, stage and treatment of the tumor should be well understood, a full preoperative plan is made, and the needle path from which the material is drawn is ensured to be located over the surgical incision so that it can be completely resected at the time of surgery.
