Abstract:
1. A device for taking a sample of soft tissue from an organ, said device comprising: a body and a needle arranged in the body and extending at least partly outside the body through a front end of the body, the needle is formed by a stylet and a cannula coaxial with said stylet along a longitudinal axis of the needle, the cannula coupled to a cannula slider comprising a first retaining element for maintaining the cannula slider in a shooting position, the stylet coupled to a stylet slider comprising a second retaining element for maintaining the stylet slider in a shooting position; an arming button manipulable to sequentially move the cannula slider and subsequently move the stylet slider from a rest position to the shooting position, thereby moving the stylet and the cannula towards a rear end of the body; a trigger mechanism configured to release the stylet slider, which in sequence releases the cannula slider to displace the stylet and the cannula from the shooting position to the rest position; wherein the stylet slider comprises a support integral with the stylet and a guide movable in the body of the device, and wherein the support and the guide are configured with a clearance between each other in a plane perpendicular to the longitudinal axis of the needle to enable a relative displacement of the guide and the support.
