Problems solved by technology

[0002] Bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. The continuous improvement has gradually increased the correct rate of diagnosis, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. Correct diagnosis requires a combination of clinical, imaging and pathology. Puncture biopsy is the main way to obtain pathological diagnosis. However, due to the uncertainty of bone tumors, it is easy to cause local spread of tumor cells due to bone tumor puncture. The direction is strictly coincident with the previous puncture needle track, and due to the effect of bone tumors, the patient's bone tissue is very easy to become fragile, and the patient may have a risk of fracture during the puncture process, but the existing devices cannot solve this problem very well. For the above problems, there is a need for a bone tumor biopsy puncture auxiliary device that can determine and record the puncture channel and the direction of the surgical knife, thereby reducing the risk of local spread of cancer cells in patients to solve the above problems
