Background
Bone and soft tissue tumors are not rare clinically, the incidence rate is on the rise year by year, the health and the life of human beings are seriously damaged, and the correct pathological diagnosis before the operation has important influence on the prognosis of the disease. Preoperative pathological diagnosis often takes the form of percutaneous needle biopsy or traditional incisional/excisional biopsy. The open/excisional biopsy has the advantage of relatively large lesion acquisition, while the pathologist can make relatively accurate diagnosis, with the disadvantage of relatively many complications, such as hematoma, tumor spread, infection of the incision, pathological fracture, etc. The percutaneous aspiration biopsy has the advantages of simplicity, rapidness, less risk of infection and hematoma and the like, however, a system clinically used for the aspiration biopsy of target tissues or the aspiration biopsy of self-body bones is simpler at present, the holding force on the target tissues is less, the target tissues are difficult to take out each time, particularly, the target tissues are difficult to take out under the condition of more soft tissues in the target tissues, the target tissues are often small in quantity and even cannot be taken out, so that the false negative rate is high or pathological diagnosis cannot be obtained, treatment is delayed, and the prognosis of a patient is influenced. One of the current solutions is to increase the number of target tissue samples, which can cause tumor spread and even delay treatment and increase treatment costs. In addition, autogenous bone grafting and bone fusion are used more and more in clinic, but the traditional incision bone taking is mostly adopted for taking autogenous bone at present, the pain of patients can be increased, and therefore, minimally invasive bone taking equipment is very necessary.
