    摘要： Differing cytology device apparatuses, and methods for their use, are provided for collecting cytology samples from within a marrzmalian body. The apparatuses and methods disclosed are minimally invasive. Some of the apparatuses include a needle having an inner lumen extending from a proximal to a distal end. A styles, having a proximal end and a distal end, is adapted to be inserted into the inner lumen of the needle to plug the inner lumen while a cyto g sample is cut in order to prevent contamination within the needle. The distal end of the styles may be sharp, and may be adapted to extend beyond the distal end of the needle to cut a cytology sample. Also included is a cytology collection device which is adapted to be inserted into the inner lumen of the needle when the stylet is withdrawn from the inner lumen of the needle. The distal end of the cytology collection device is extended beyond the distal end of the needle in order to collect the cytology sample, and then retracted inside the needle after collecting the sample. In one embodiment, a cytology collection device comprises an elongate member having a plurality of bristles near its distal end. In another embodiment, a cytology collection device comprises an inflatable balloon. In yet another embodiment, a cytology collection device comprises a wire mesh device. In a further embodiment, the apparatus may include an endoscope which contains a transducer emitting ultrasound waves which are used to determine a position of the cytology collection device within the body.

    摘要： A single-use biopsy instrument for mounting at a multiple-use biopsy apparatus, comprises a cartridge enclosing proximal end portions of a canula, a finger tube slidingly disposed on the canula, and a stylet slidingly disposed in the canula. The canula and the finger tube have proximal holding portions and are displaceable in regard of the cartridge by displacement means disposed in the biopsy apparatus engaging with the holding portions through one or several engagement openings in one wall of the cartridge. Also disclosed is a corresponding biopsy apparatus.

    摘要： The invention relates to a coaxial cannula (1) for extracting samples from tissue comprising a biopsy needle unit (9) provided with a space for sample extraction and a sample separation unit (21) which coaxially encompasses the biopsy needle (9) on an external wall and is longitudinally movable. The inventive coaxial cannula (1) comprises a sealing element (3) which is arranged on the proximal end thereof and closes the space between the internal wall of the coaxial cannula and the external wall of the sample separation unit. Said coaxial cannula (1) is characterised in that the sealing element (3) opens an air outlet when the biopsy needle unit (9) is inserted, and prevents air intake when the biopsy needle unit (9) is positioned and vacuum is produced in the internal chamber of the biopsy needle.

    摘要： A minimally invasive apparatus and method for harvesting bone marrow cells, blood, and bone fragments includes a rigid cannula having a proximal end and a distal end with an opening. The distal end includes a cutting tip that is movable axially and radially to cut and disrupt bone tissue while preserving necessary viability among harvested marrow cells. The cannula further includes an inner surface defining an internal passage that extends from the opening toward the proximal end. Suction is applied to the passage to draw disrupted bone marrow cells, blood, and bone fragments into the internal passage for collection. The apparatus may include a rotatable shaft disposed co-axially within the internal passage. The shaft has a distal end with a cutting bit for further cutting and disrupting of bone tissue.
