ABSTRACT:
A biopsy sampling device, particularly adapted for bone marrow sampling, which includes a needle having a lumen formed therein, along with a removably disposed stylet. The needle is provided with a sharpened cutting edge, when desired, particularly when designed for bone marrow sampling. A gripping means is disposed about the proximal end of the needle, with the gripping means including a generally solid finger-gripping member with portions extending laterally of the needle, and with the finger-gripping member having a needle-receiving bore extending generally centrally through the member. The solid finger-gripping member has a pair of opposed channels formed along the outer surfaces thereof, with the axes of the channels being arranged at right angles, one to another, with one axis being generally parallel to the needle axis, and with the other axis being generally transverse to the needle axis. In an alternate embodiment, the biopsy sampling device is provided with a removable cap for maintaining the stylet in proper inserted disposition, with the distal end of the cap of the stylet being provided with means for achieving proper orientation of the stylet. Also, a guard is provided over the distal end of the body of the needle, with the guard having internal threads which mate with threads arranged along a distally extending projection sleeve of the finger-gripping member.
