[A new instrument for percutaneous biopsy of bone and joint].
A newly designed percutaneous biopsy instrument has been used clinically. The instrument consists of parts of clamping, aspiration, spooning, cutting and rotational scraping in accordance with the pathological tissue or specimens. This instrument is called CCACS system. In use, the instrument with its protective cannula is punctured into the objective tissue percutaneously. Then a suitable part of the instrumental components is chosen and put through the cannula into the lesion to get sample, repeatedly if necessary. The system was used to take specimens from 61 patients with tumours (malignant 23, benign 28) or inflammations (10) of torso, limb bone or joint. It was successful in 59 patients (96.72%) and failed in 2 patient (3.28%).
