A puncture information output unit (27) outputs puncture support information of the puncture needle that is based on the position / posture information obtained by the position / posture information acquisition unit, and a display control unit superimposes the puncture support information on an image to generate a superimposed image and displays the superimposed image on a display.

This invention relates to a crossbow-type prostate biopsy gun with adjustable puncture depth, belonging to the field of medical device technology. It includes a piercing needle, a detachable puncture needle, a needle core, a limiter, a chamber, a support plate, a bolt-action mechanism, a loading device, a firing device, a safety device, and a needle magazine. One end of the support plate is fixed with the piercing needle, which contains a puncture needle with a needle core inserted into it; the length of the puncture needle is shorter than the length of the needle core. The rear ends of both the puncture needle and the needle core have baffle-like protrusions. The support plate surface has a chamber, a bolt-action mechanism, a loading device, and a firing device corresponding to the baffle-like protrusions. The front end of the support plate has a limiter for adjusting the puncture depth. The support plate also has a puncture needle removal device and a needle magazine for storing and releasing puncture needles one by one. The end of the needle core near the needle tip has a tissue groove. This invention provides a biopsy gun with adjustable puncture depth, prevention of needle tract implantation, and rapid puncture capability.
