Die vorliegende Erfindung betrifft eine Resektoskopvorrichtung (10), umfassend einen Schaft (18), eine Bilderfassungseinrichtung (36), die an einem distalen Endstück (34) des Schafts (18) angeordnet ist und einen Beobachtungsbereich (38) definiert, ein Resektionswerkzeug (20) mit einer Werkzeugspitze (28) und einem Trägerarm (26) und ein Gelenk (110), mittels dessen der Trägerarm (26) gelenkig abwinkelbar ist, wobei in zumindest einer Winkelstellung des Trägerarms (26) ein Abstand (130) zwischen der Werkzeugspitze (28) und einer Längsachse (132) des distalen Endstücks (34) einen Radius (134) eines Querschnittsprofils (136) des distalen Endstücks (34) um wenigstens einen Faktor 2 überschreitet.

The present disclosure is generally related to a device for holding a Printed Circuit Board (PCB) or similar electrical component. Some electrical devices benefit from having foam inside an outer metal enclosure to hold the various components. The foam can assist with one or more of airflow, device mounting, noise dampening and shock absorption. However, one challenge that exists, especially for high frequency electronic devices, is that the foam being in contact with the PCB can potentially cause electrical interference issues. As such, an exemplary embodiment is directed to an improved PCB securing structure. One exemplary aspect is directed to a PCB clip and support block that secure a PCB to and electrically isolate the PCB from the support block. Another exemplary aspect is directed to a monolithic PCB clip that secures a PCB to mounting foam within an enclosure and electrically isolates the PCB from the mounting foam.

Shielding enclosure for electronic equipment comprises a cover (80), which has at least four sides. One or more of the four sides includes one or more fingers (90). Each of the fingers (90) includes a base (92) connected with the cover (80) and a front portion. The fingers are cut on three sides from the cover (80), and are configured to frictionally engage through tension a portion of another cover (40) of the enclosure between the cover (80) and each of the fingers (90). The shielding enclosure is particularly configured to provide an EMC shielding for the electronic equipment.

A signal adapter device for interfacing a medical camera with a processing device is disclosed. The signal adapter device comprises a first interface configured to receive video signals from a medical camera and a second interface configured to transmit converted signals to a processing device. A processing unit converts video and control signals between different formats. The signal adapter device includes a mechanical locking mechanism at the second interface to prevent unintentional disconnection, while allowing the first interface to remain freely detachable. The housing incorporates thermal management structures to dissipate heat from internal components and, optionally, from the connected camera. The signal adapter device may further regulate power supplied to the camera, with optional electrical isolation.

An exemplary aspect is generally directed to generating various compositions of input video information for streaming to one or more displays. For example, a first display can be configured to show a first video stream and a second video stream. The first video stream can be a live view of video from an endoscope, and the second video stream can be from a (remote) camera control unit. These streams are presented in a PIP (Picture-in-Picture) mode, or in a PAP (Picture-and-Picture) mode. Any of the video streams or other information are selectable for display and any combination thereof is selectably configured for streaming to any selected display. Additional aspects relate to a video rendering system where the dominant image is a 3D image stream and the subordinate image (such as in PiP) is the same image stream, but in 2D. Even more aspects relate to a video rendering system where the dominant image is a 2D image stream and the subordinate image is the same image stream, but in 3D.

The present disclosure is generally related to a cooling system for an electronic device. Some electrical devices benefit from having foam inside an outer metal enclosure/chassis to hold the various components. The foam can assist with one or more of airflow, device mounting, noise dampening and shock absorption. However, one challenge that exists is that foam can present challenges for heat dissipation from the various electronic components. One exemplary aspect is directed to a fan-based cooling system for electronic devices that are mounted in a foam support structure. Another exemplary aspect is directed to a fan-based cooling system for electronic medical devices that are mounted in a foam support structure. Yet another exemplary aspect is directed to a fan-per-component group solution for cooling an electronic device.

An exemplary aspect is generally directed toward a state-changing status/power switch. Even more specifically, one exemplary aspect is generally directed toward an illuminated state-changing status switch that provides context regarding an operational state of an associated piece of equipment, such as a medical device. The context can be provided via one or more of an illumination state of the switch, text on the switch and/or icons on the switch. Alternatively or in addition, the switch can include color-changing capabilities with, for example, white or green being an operational state, orange or yellow reflecting a state between power-on and power-off, and white being a powered-down or standby state.

Die vorliegende Erfindung betrifft eine Resektoskopvorrichtung (10), umfassend eine Einführhülse (12), die einer Kavität (14) eines Patienten zuführbar ist und einen ovalen Querschnitt (110) aufweist, und einen Schaft (18), der sich durch die Einführhülse (12) erstreckt und der einen ersten Schaftabschnitt (130) und einen zweiten Schaftabschnitt (140) aufweist, die an unterschiedlichen Positionen entlang einer Längsachse (120) des Schafts (18) angeordnet sind, wobei zumindest in einer Anwendungskonfiguration der erste Schaftabschnitt (130) in der Einführhülse (12) angeordnet und innerhalb der Einführhülse (12) drehbar ist, und wobei der zweite Schaftabschnitt (140) in der Anwendungskonfiguration außerhalb der Einführhülse (12) angeordnet ist.

A medical illumination device (40) and a medical system for supplying a light beam into a medical instrument (10) having a light guide (25), in particular of an endoscopic instrument, comprises a light source unit (44) having at least one light source (46), an optical fiber unit (50) having a light source end (502) connectable to the light source unit (44) and an instrument end (504) connectable to the medical instrument (10), an diaphragm unit (60) moveably arranged between the at least one light source (46) and the optical fiber unit (50), and a drive unit (85) for moving the diaphragm unit (60) relative to the optical fiber unit (50). The diaphragm unit (60) comprises several openings (600) each comprising a different diameter. The optical fiber unit (50) comprises a plurality of optical fibers (510) in an ordered arrangement such that an input end (512) and an output end (514) of the optical fibers are located at equal radial distance to a longitudinal axis (L) of the optical fiber unit (50). The drive unit (85) moves the diaphragm unit (60) such that a selected opening (602; 604; 606; 608) is positioned in a light beam (42) provided by the light source unit (44) for defining a diameter of an input light beam (43) entering the medical instrument (10). A method for supplying a light beam into the medical instrument (10) selects an opening (600) to be moved into the light beam (42) according to at least one operating parameter value of the medical instrument (10) for defining a diameter of the input light beam (43) entering the light guide (10).

Die Erfindung betrifft eine Bildgebungsvorrichtung (10; 110; 210), insbesondere eine Endoskopvorrichtung, mit einem Schaft (12; 112; 212), welcher eine Längsachse (14; 114; 214) definiert, und mit einer Stereoskopieeinheit (16; 116; 216) zur stereoskopischen Bilderzeugung. Es wird vorgeschlagen, dass die Stereoskopieeinheit (16; 116; 216) eine Bewegungseinheit (20; 120; 220) zu einer mechanisch bewirkten Änderung eines Auswahlbereichs (22, 22'; 122, 122'; 222, 222') aus einem Sichtfeld (24; 124; 224) der Stereoskopieeinheit (16; 116; 216) für eine Bilderfassung aufweist, wobei die Stereoskopieeinheit (16; 116; 216) dazu eingerichtet ist, den Auswahlbereich (22, 22'; 122, 122'; 222, 222') zur Erfassung von Bildern zur Nutzung bei der stereoskopischen Bilderzeugung in Abhängigkeit von einem Rotationsparameter bezüglich der Längsachse (14; 114; 214) festzulegen.
