An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component of the surgical cutting assembly responsive to actuation of the torque generation component.

The needle arrangement is adapted to bet set in: a closed position, in which the sealing member (204, 1003, 1403) is arranged to abut at least a portion of a front end surface of the needle sheath (104, 1002, 1402) thereby restricting intrusion of foreign matter in an area between the needle sheath and the needle, and an open position, in which a gap (1204, 1506) is formed between the sealing member (204, 1003, 1403) and the front end surface of the needle sheath (104, 1002, 1402). Embodiments include needle arrangement for injection, for aspiration, and for biopsy purposes.

MICROBIOPSY DEVICE
20230015756 · 2023-01-19 ·

An improved microbiopsy needle tip is described. The improvement is attributable to the presence of one or more combinations of features, including the use of a Franseen-type needle cutting tip, the provision of a “step-out” in which the collection portion of the biopsy device has a larger diameter than the procuring portion of the device, frictional force on the core of tissue exerted by the distal portion of the needle, which force is provided by the diameter of the distal collection portion of the device having substantially the same diameter as that of the procured core of tissue, the mechanical effects of scaling the needle to small dimensions; and the use of a needle that can be curved to as to sample multiple biopsy sites in close proximity without retracting the needle from the patient.

Biopsy probe mechanism having multiple echogenic features

A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and a sample receiving notch. A cutting cannula is arranged coaxially with the elongate sample receiving member. The elongate sample receiving member and the cutting cannula are movable relative to one another along the longitudinal axis between a first relative position and a second relative position. A plurality of echogenic features include a first echogenic feature established on the elongate sample receiving member and a second echogenic feature established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position.

Core needle biopsy device for collecting multiple samples in a single insertion

A core needle biopsy device includes a body, a needle assembly and a drive assembly. The needle assembly extends distally from the body and includes a hollow piercer and a hollow cutter. The piercer is disposed within the cutter. The cutter includes a distal tip and a swaged portion proximate the distal tip. The drive assembly is configured to selectively cock and fire the piercer and the cutter.

Set of sampling parts

A set of medical sampling parts for use with an endoscope, including: a sampling device; a sample container including a separator part located at a top of the sample container, a base located at a bottom of the sample container opposite of said top, and a container part at least partly enclosing a sample volume located at the bottom of the sample container, so that a container axis extends between said separator part and said base; and a connector for connecting the sampling device with the sample container, wherein the sample container can be detached from the sampling device by a translational movement along a detachment axis, whereby a smallest angle between said container axis and said detachment axis is equal to or greater than 45 degrees.

Endosurgical device and method of use

An endosurgical device is provided. The endosurgical device comprises a flexible tube having at least two lengthwise extending channels, an end effector comprising two opposite jaws having opposite cutting edges, an effector sleeve that surrounds the tube at least at the distal tube end, and means for reciprocating the end effector axially in relation to the effector sleeve to close the jaws when the effector sleeve is moved forward and backwards to close and open the jaws, respectively. The exterior face of the opposite jaws is electrically insulated, and an electrical cord for providing current to the end effector extends inside one of the lengthwise extending channels of the tube. The endosurgical device may allow the surgeon to take several tissue specimens from an organ and to perform several functionalities when the device is inside the organ.

Manifold and Tray for Collecting a Tissue Sample
20220409191 · 2022-12-29 · ·

A tray and a manifold for collecting a tissue sample under influence of a vacuum. The manifold includes a sleeve, and the tray includes a sealing member configured to be removably positioned in sealing engagement with the opening. A basket defining a tissue collecting cavity, and a base portion includes at least one rib disposed within said tissue collecting cavity. The rib(s) define pockets arranged in series in the proximal-to-distal direction so as to provide low pressure regions when the tray is being removed from the sleeve. The rib(s) may be transverse to a longitudinal axis, and/or arcuate in a shape complimentary to the base portion. The base portion defines porous features that may be arranged in groupings A sealing edge in sealing engagement with an upper barrier of the sleeve may delay an onset of airflow entering the tissue collecting cavity.
