Acupuncture biopsy needle positioning device

The utility model aims to provide a needle biopsy needle positioning device, and belongs to the technical field of medical instruments. The bed comprises a bed board, a bevel protractor and a measuring ruler detachably installed on the bevel protractor. A sliding block I capable of sliding up and down on the measuring ruler is mounted on the measuring ruler, and a biopsy needle clamping mechanism is mounted on the sliding block I; guide rails are arranged on the two sides of the bed board, sliding blocks II matched with the guide rails are installed on the guide rails, and the two ends of the angle ruler are connected to the sliding blocks II respectively. Under the synergistic effect of the bevel protractor, the measuring ruler, the sliding block I and the sliding block II, the biopsy needle can be freely positioned in a three-dimensional space, the puncture position can be quantitatively adjusted, meanwhile, deviation of the puncture direction caused by hand shaking is avoided, the puncture success rate is
