Abstract

A biopsy instrument which can be used to take a bone biopsy sample or a soft tissue biopsy sample. The biopsy instrument includes a biopsy needle and a biopsy gun. The biopsy gun includes a firing mechanism for firing the biopsy needle with a minimum force for striking and penetrating the target tissue organ; a cradle that securely holds the biopsy needle with an attached disposable syringe having a plunger; and a triggering mechanism. In operation, the triggering mechanism actuates the firing mechanism causing the cradle together with the needle and the attached syringe to fire forward with a sufficient force such that the needle penetrates the target tissue organ causing a first a first tissue sample to be cored in the needle. The disposable syringe can then be used to obtain a second tissue sample up through the biopsy needle using a vacuum created in the disposable syringe when the plunger is maintained in a rearward position while the syringe fires forward. In a bone biopsy procedure, the first tissue sample is a bone sample and the second tissue sample is a liquid bone marrow sample.
