  • Publication number: 20220361858
    Abstract: A biopsy needle arrangement comprises a needle sheath and a needle. The biopsy needle arrangement is configured to be operatively connected to an actuator device configured to push the needle and the sheath distally in a sliding direction x. The biopsy needle arrangement further comprises a needle connector configured to attach the needle to the actuator device and a sheath connector configured to attach the needle sheath to the actuator device. The needle connector is configured to disengage the needle from the actuator device when the needle is subjected to a force in the sliding direction, which exceeds a threshold force. Also or alternatively, the sheath connector is configured to disengage the needle sheath from the actuator device when the needle sheath is subjected to a force in a direction opposite the sliding direction, which exceeds a threshold force.

  • Publication number: 20220346762
    Abstract: An actuator device comprises first, second and third actuators operatively connected to a biopsy needle arrangement comprising a needle inside a sheath. The needle arrangement has a closed state and an open state, a tip portion abutting a needle sheath in the closed state, and the tip portion extending from the distal end of the needle sheath in the open state. The first actuator pushes the needle distally in a sliding direction x relative to the needle sheath a first distance, d1, at which the needle arrangement is in its open state. The second actuator pushes the needle sheath distally in the sliding direction x relative to the needle a second distance, d2. The third actuator pushes the needle sheath distally in the sliding direction x relative to the needle a third distance, d3, where d3 is smaller than d2, at which the needle arrangement is in its closed state.

  • Publication number: 20030054097
    Abstract: A device for spinning a liquid sample on a sample carrier (2), such as a microscope slide, comprises a rotatable body (4) with a receiving surface (11) for the sample carrier (2), and a chamber (10) for enclosing a sample that has been applied to the sample carrier (2). A means (23) is designed to establish a gas flow from the environment into the chamber (10) in connection with the spinning of the sample in order to prevent leakage of the sample to the environment. Unlike current designs, the chamber (10) is arranged on the same side of the sample carrier (2) as the rotatable body (4). Consequently, the sample carrier (2) itself serves as a cover which seals the chamber (10).

  • Patent number: 6361148
    Abstract: A direct electrostatic printing device and method print an image to an information carrier with improved alignment between printed part images from two or more print stations. The improved alignment is based on a basic mechanical alignment with a basic accuracy between the print stations which is improved by an electronic alignment of the corresponding bitmaps. The electronic alignment is made possible by the capability of at least one print station to print at least one additional dot in relation to the corresponding bitmap. The minimum number of additional dots being dependent on the attained basic accuracy of the basic mechanical alignment.
