Bone biopsy for the clarification of ambiguous lesions has until now been the last resort in diagnostic procedures because obtaining the material for histological evaluation has involved very traumatizing methods (biopsy by surgical intervention, percutaneous biopsy with high-caliber needles). A new bone-biopsy apparatus has now been developed that is provided with a cannula not much larger than a fine needle (1,4 mm); it can be used to obtain histologically evaluable biopsy material from almost all regions of the skeletal system. As the procedure can be carried out under local anesthesia, there is no undue stress to the patient. The complication risk is no higher than when using conventional fine-needle biopsy. Despite the small diameter of this needle it is possible to obtain biopsy specimens not only of osteolytic but also of osteoplastic lesions. An electric motor (20 rotations/min) is the power source for apparatus. The value of bone biopsy in diagnostic procedures has increased considerably.
迄今为止，为明确不明确的病变而进行的骨活检一直是诊断程序中的最后手段，因为获取用于组织学评估的材料涉及非常具有创伤性的方法（通过手术干预进行活检、使用大口径针进行经皮活检）。现在已经开发出一种新的骨活检设备，其配备的套管不比细针大多少（1.4毫米）；它可用于从骨骼系统的几乎所有区域获取可进行组织学评估的活检材料。由于该操作可在局部麻醉下进行，对患者没有过度的压力。并发症风险不高于使用传统细针活检时的风险。尽管这种针的直径很小，但不仅可以获取溶骨性病变的活检标本，也可以获取成骨性病变的活检标本。电动马达（每分钟20转）是该设备的动力源。骨活检在诊断程序中的价值已大幅提高。
