摘要：
An automatic biopsy gun is described, the gun comprising a body and a needle cantileverly extending from the body. The needle comprises a stylet provided with a collecting hollow to collect a tissue sample, and a cannula in which the stylet is slidingly housed so that the collecting hollow can come out of the cannula and go back in it with a guillotine effect. The gun further comprises a pushing member to push the cannula and a pushing member to push the stylet, both being movable in the body between a forward position and a rearward position in order to slide the stylet with respect to the cannula. Elastic countering means counter the pushing members which are loaded by driving means operable by the user. Advantageously, pushing members are guided by inner guides that are inside the gun body and the guide of the cannula is closer to the needle than the guide of the stylet.
