Disposable automatic and universal gun. A “guillotine cutting system” is applied in order to perform any kind of soft tissue histological biopsy. Two optional triggers are applied on the device, in order to enable any bioptic procedure in an easy way. A safety system is also applied on the device. Any time the device is loaded, the system gets set in action automatically; this helps the percutaneous operation, avoiding a shooting risk. An indicator is also applied to show the needle loading at any time. The cannula tip was designed to make the tissue penetration, the tissue cutting and the bioptic sampling as less traumatic as possible.The needle cannula is centimeter marked in order to make the procedure as precise as possible. An echogenic marker is placed on the distal part of the cannula. By using an ultrasonic machine, the marker enables the needle to be constantly seen during the whole procedure. A colour code is meant to help the user to identify the device diameter; this code is recognized on international level.
