A tissue handling system includes a biopsy device and a tissue storage container separate from the biopsy device. The biopsy device has a cutting cannula, a housing, and a tissue collecting device. The tissue collecting device is detachably received in the housing. The tissue collecting device is configured to receive at least one tissue sample. The tissue storage container is configured to detachably receive the tissue collecting device after the tissue collecting device is disengaged from the housing of the biopsy device to deliver the at least one tissue sample from the tissue collecting device to the tissue storage container.

A medical needle arrangement (100, 1000, 1400) is disclosed. The needle arrangement (100, 1000, 1400) comprises: a needle sheath (104, 002, 1402), and a needle (202, 1102, 1406) comprising: an elongated portion and a sealing member (204, 1003, 1403) being arranged to a front end of the elongated portion. 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.

Medical devices and methods for removing a predetermined shape of soft tissue from a target tissue layer, thereby leaving a matching channel with predetermined geometry and orientation in the target tissue layer, are described. The medical device comprises coaxial outer and inner elongated members extending along axis X; said outer member comprises an open distal side and a first distal part configured for sticking to said target tissue layer during forward axial movement; said inner member comprises a second distal part configured to rotate and project distally through said open distal side to cut said predetermined shape of the soft tissue from the target tissue layer and create said channel formed as a hole across the target tissue layer.

The invention relates to a biopsy needle device comprising at least one hollow outer needle, an inner needle longitudinally movably guided in the outer needle, and a housing. Such a biopsy needle device can be used to carry out a biopsy on a living being, offering improved ergonomics.

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.

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.

Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.

The present disclosure relates generally to the field of medical instruments. In particular, the present disclosure relates to a biopsy cap and endoscope biopsy cap housing with improved stability and stress distribution to securely and removably attach to an endoscope biopsy port. In one example, a biopsy cap housing may include a first center-split half comprising a first half of an upper and lower chamber and first pivot member, and a second center-split half comprising a second half of an upper and lower chamber, and second pivot member, wherein mating surfaces of the first and second center-split halves may be configured to interlock to define the upper and lower chambers.

A biopsy device includes a probe, a holster, and a probe lock. The probe includes a probe body and a needle extending distally from the probe body. The probe is releasably couplable to the holster. The probe lock includes a lock member configured to move laterally relative to a longitudinal axis defined by the needle to selectively lock the probe to the holster.

A biopsy device includes a cannula and a specimen collector. The cannula has a proximal end and a longitudinal axis. The specimen collector contains the proximal end of the cannula. The specimen collector has a removable sample receiving cartridge that is removable along the longitudinal axis of the cannula to expose the proximal end of the cannula.
