[Clinical application of CT stereotactic device in biopsy of brain lesions].
A new CT stereotactic device named version WL-86 was designed and manufactured by the authors. Phantom puncture and cadaver puncture tests showed that its accuracy is less than 1 mm. We have also made a new type of biopsy needle--the rotary and translational cutting biopsy needle. A definite pathological diagnosis was made in 93.7% (30/32) of patients by this technique: The practicability of the device, the indications and clinical value of CT-guided stereotactic biopsy were discussed.
