  • Publication number: 20230355085
    Abstract: The tube has a first lumen with a proximal end and an open distal end to be placed inside a body cavity. An outer wall encloses the first lumen and a camera lumen. A camera module (10) is arranged in the camera lumen at a distal end thereof so that the camera module is positioned adjacent the distal end of the first lumen. An image transmission cable (13) attached to the camera module extends through the camera lumen to connect to an image display device. The camera module is fixed in the camera lumen by means of a camera housing (14) including a tubular housing part (17) surrounding the camera module and a distal end wall (18). The tubular housing part and the distal end wall are integrally moulded and form one single housing element (19). The tubular housing part fits tightly into the camera lumen of the tube.

  • Patent number: 11457901
    Abstract: A tissue collection device (1) for collection of one or more exposed tissue samples (2) from a biopsy needle or biopsy device, which tissue collection device comprises one or more pieces of a carrier medium (6) and is arranged to temporarily bring a piece of carrier medium into physical contact with the tissue sample, while the tissue sample is still positioned in the biopsy needle or biopsy device, so that the tissue sample (2) adheres to the carrier medium (6) and is removed from the biopsy needle (3) or biopsy device (4) with the carrier medium (6), when the carrier medium (6) is removed from the biopsy needle or biopsy device again. Furthermore, a biopsy device comprising such a tissue collection device is disclosed.

  • Publication number: 20220088333
    Abstract: A catheter having a distal end for insertion into a patient and including: a catheter tube enclosing at least a first catheter lumen and a vision lumen separated from the first catheter lumen, the first catheter lumen having a first distal opening at the distal end of the catheter; a window closing off a distal end of the vision lumen and having a planar interior window surface facing the vision lumen and a planar exterior window surface; and a vision device positioned in the vision lumen and having a vision module, such as a camera with an image sensor or an optical fibre, having an optical axis extending through the window; wherein the interior window surface and/or the exterior window surface is/are non-orthogonal with respect to the optical axis of the vision module, and the window surfaces are non-parallel.

  • Publication number: 20200248132
    Abstract: The present disclosure relates to a method for attaching, detecting and retrieving a single cell on a manipulation medium comprising the steps of: attaching the single cell onto the manipulation medium by applying a carrier liquid; partially drying out the carrier liquid; detecting a property of the single cell by rotating the manipulation medium and scanning a light beam over the manipulation medium; loosening the single cell from the manipulation medium without damaging the single cell by manipulating the single cell with an instrument; and retrieving the single cell from the manipulation medium by aspirating the single cell into a tube, wherein the carrier liquid is dried out to a degree corresponding to that the single cell does not move during the rotation of the manipulation medium and that the single cell can be loosened by the instrument without damaging the single cell.

  • Publication number: 20190282762
    Abstract: An injection device with a dose delivering mechanism being adapted to provide a non-visual, e.g. audible and/or tactile, feedback signal when a set dose has been at least substantially injected. A first and a second part of the injection device are adapted to perform a relative rotational movement with respect to each other. The relative rotational movement causes at least two parts of the injection device to abut or engage, and this abutment or engagement causes the non-visual feedback signal to be generated. A very distinct and precise feedback is provided as compared to prior art axial solutions because the generation of the feedback signal is initiated by the relative rotational movement. Feedback signal may be generated by a change in a rotational velocity of at least one part, e.g. by changing the pitch of a threaded portion or by engaging a non-rotating part and a rotating part, thereby causing the non-rotating part to start rotating.

  • Patent number: 8911411
    Abstract: An injection device with a travelling clutch which can be shifted between two different positions by the activation of an injection button. In the first position, the injection button and the driver is allowed to rotate relatively to the piston rod, which is blocked from rotation by the clicker element. In the second position, the drive sleeve and the injection button is axially movable while the piston rod is allowed to rotate.
