Abstract: A module for a visualization apparatus includes an imaging optic accommodated in a base body for generating a viewing image of an object region with an optical viewing beam path. The module includes a display unit for visualizing an image superimposed on the viewed image of the object region with orientation information. The module has an image acquisition unit having an image sensor for acquiring an image of the object region. The module contains a switching unit for selectively providing and blocking an optical beam path from the display to the image sensor. The switching unit, in a first switching state, provides the image of a geometric structure on the display onto the image sensor with the optical beam path and, in a further switching state blocks the optical beam path from a geometric structure on the display to the image sensor.

Abstract: A method of installing a prosthesis assembly includes installing a base component in a prepared glenoid vault, axially aligning a plurality of slots in one of a stretched glenoid bearing component and a base component with a plurality of ridges in the other of the glenoid bearing component and the base component, each of the plurality of slots having a maximum length which is greater than a maximum length of a respective one of the plurality of ridges, engaging each of the plurality of ridges with the respective one of the plurality of grooves thereby rotatably coupling the glenoid bearing component and the base component and limiting axial movement of the glenoid bearing component relative to the base component, and placing the bearing surface into articulating contact with a humeral head.

Abstract: A microscopy system method for inspecting a retina of an eye including generating an inverted intermediate image of the retina using an opthalmoscopic lens; detecting a left image of the intermediate image from a left viewing direction and detecting a right image of the intermediate image from a right viewing direction; and displaying an inverted representation of the detected left image to a right eye of a user and displaying an inverted representation of the detected right image to a left eye of the user.

Abstract: This technology relates to a one-piece sleeve which envelops a chamber with a baffle in a firearm suppressor body. The one-piece sleeve has an elongate opening, or slot, extending longitudinally along all, or part of, the length of the sleeve. The slot may be straight or curved. Also, there may be a plurality of slots. This way, because of the slot(s), the sleeve has increased flexibility and may be easily slightly opened up, and more easily removed from the elongate suppressor body for cleaning.

Abstract: A method for retraction useable in joint arthroplasty. The method includes using a joint retractor having a first arm and a second arm. The first arm has a first portion and a second portion and the second arm having a first portion and a second portion. The retractor is inserted into a surgical opening of a patient's shoulder joint. The second portion of the first arm is placed against the coracoid process and the second portion of the second arm is placed against the resected humerus. The first portions of the first and second arms are hung over the resected tissue to allow exposure of the glenoid.

Abstract: The invention relates to a respiratory device for keeping a patient breathing artificially or support his or her breathing naturally. Said respiratory device comprises an air inlet, an air source, and at least one proportionally adjustable control valve. The control valve is provided with a housing (11) and a rotary valve (12) which is arranged in the housing so as to be twistable about the longitudinal axis thereof and which allows through-holes (11d) of the housing (11) to be entirely or partially closed by twisting the rotary valve (12). The rotary valve (12) and a corresponding support surface (11f) of the housing (11) have a conical shape, the support surface (11f) cooperating with the rotary valve (12). The through-holes (11d) are disposed in the area of the support surface (11f).

Abstract: A spreadable retractor for use in joint arthroplasty. The retractor includes a first arm having a first portion and a second portion that is movably coupled to the first portion. The second portion is also coupled to a first retaining member that is sized and shaped to retain a portion of a coracoid process. A second arm is also included in the retractor and is movably coupled to the first arm. The second arm has a first portion and a second portion that is movably coupled to the first portion. Also, the second portion is coupled to a second retaining member that is sized and shaped to couple to a resected humerus.
