    Abstract: A bone biopsy needle assembly includes an elongated tubular cannula having an axially extending lumen therethrough. A guide is provided to facilitate insertion of a probe into the cannula for sample removal. The guide has a molded shape with an elongated dimension having first and second ends. A cylindrical opening extends through the length of the elongated dimension and has a diameter substantially equal to that of the interior lumen of the cannula. A flared outward enlargement of the cylindrical opening at each of the first and second ends provides for easy alignment of one of the ends with the distal end of the cannula and the other end forms a guide for insertion of a probe into the distal end of the cannula for removal of the biopsy specimen.

    Abstract: A bone biopsy needle assembly which includes a handle having a proximal concave curved surface having an off-center radius producing a first relatively narrow end and a second relatively wide end of the handle. The wide end is curved to conform to the shape of a user's palm, and the narrow end forms a surface to limit lateral slippage in the direction of the user's forefinger. The handle also has a distal surface with a receiving opening. A cannula has a central lumen, with a first end extending into the receiving opening and being connected to the distal surface of the handle toward the relatively narrow end and having a second end extending distally from the handle. A removable stylet is slidably received within the lumen and has a proximal knob carried by the handle.
