The invention creates a hand surgical instrument with a seal to an optic that is easy and inexpensive to manufacture and can be thoroughly cleaned. This is achieved by a hand surgical instrument having a main body with a shaft. In this instrument, the main body has at least one channel-like bore for an optic. This bore can merge into a tube section in the proximal direction, so that a telescope including optics can be installed through the tube section and the bore in the distal direction of the instrument. A distal end of the main body can be coupled with the shaft for the optics and a proximal end with the telescope. A longitudinal axis of the instrument can be defined by the bore and the tube section. A key feature is that a sealing body with a concentric sealing lip is arranged axially to this longitudinal axis in the proximal direction, whereby this sealing lip is oriented in the proximal direction.

The invention relates to a cystoscopy system 1 and a diagnostic method for flexible cystoscopy. The cystoscopy system 1 comprises a flexible cystoscope 3, a video processing unit 4, a user interface 5 and a computer based clinical decision support system 2. An AI model 24 is stored on the memory 21. The AI model 24 is trained on a dataset comprising multiple images of blood vessels 14 in bladder tissue. The cystoscope 3 captures video data 10 of tissue and transmits the video data 10 to the video processing unit 4. The video processing unit 4 processes the video data 10 and transmits the processed video data 10 to the processor 20. The processor 20 performs an inference operation in which the video data 10 is applied to the AI model 24 to detect abnormalities of blood vessels 14 in the video data 10 and highlight the abnormalities in the enhanced video data 11, 12. The enhanced video data 11, 12 is display on the user interface 5 to medical personnel.

A system for navigation and/or control support for transurethral prostate resection (TURP), comprising a controller configured to carry out the following steps:a) analysing endoscopic images provided by a resectoscope (20) and/or additional sensory data from within the resectoscope (20) during TURP for one or more of several options, and at least one ofb) automatically disabling HF current to the resection electrode (24) under several different outcomes of analysing step a), andc) outputting visual and/or acoustic information to an operator performing the TURP, the information comprising at least one ofi) a visual indication of an anatomical landmark inside and/or outside of the endoscopic image,ii) a visual indication of a distance of the resection electrode (24) to an anatomical landmark, andiii) a visual or acoustic warning signal when the resection electrode (24) comes closer than a predetermined allowable distance to one or more of the bladder neck (10), the verumontanum (10) and the internal and/or external sphincter muscles (6, 8).

The invention provides a bridge for a hand surgical instrument, with which all working instruments and the optics can be inserted into and removed from the hand surgical instrument in a simple and clear manner. This is achieved in that a bridge (12) for a hand surgical instrument (10) has a main body (20) in which a channel-like bore (19) for an optical system and at least one working channel (26, 28) for receiving at least one working instrument are arranged. A plane (24) can be laid through a longitudinal axis (18), which divides the space around the bridge (12) into an upper half-space (25) and a lower half-space (26). The at least one working channel (26, 28) extends from the main body (20) in the direction of the upper half-space (25).

Die Erfindung betrifft ein bipolares Elektrodeninstrument zur Verwendung in einem Resektoskop, wobei das Elektrodeninstrument einen langgestreckten Schaftabschnitt aufweist, durch den hindurch sich ein erster Leiter erstreckt, der am distalen Ende des Elektrodeninstruments eine mit Hochfrequenzstrom beaufschlagbare Arbeitselektrode bildet, wobei sich ferner durch den Schaftabschnitt ein zweiter Leiter erstreckt, der im distalen Endbereich des Elektrodeninstruments eine Gegenelektrode bildet, dadurch gekennzeichnet, dass die Arbeitselektrode und die Gegenelektrode räumlich derart voneinander getrennt sind, dass der Abstand zwischen ihnen nicht mittels eines geraden Leiters überbrückbar ist, der eine Länge von 6 mm oder weniger aufweist. Darüber hinaus betrifft die Erfindung Resektoskope für die endoskopische Chirurgie mit einem Hüllrohr, dadurch gekennzeichnet, dass innerhalb des Hüllrohres ein erfindungsgemäßes Elektrodeninstrument längsverschiebbar gelagert ist.

Provided is a computer-implemented method of estimating a risk that a medical instrument has been cross-contaminated with a problematic pathogen, comprising: obtaining data identifying a plurality of medical instruments provided in a facility; obtaining data representing use of some or all of the plurality of medical instruments in a plurality of first procedures on a plurality of first patients; storing in a database, for each of the used medical instruments, first data identifying the patient on which the medical instrument has been used; reprocessing the used medical instruments; - storing in the database, for each of the reprocessed medical instruments, second data identifying at least one reprocessing modality; determining, for each of the plurality of first patients, a first indicator representing whether a respective first patient carries a problematic pathogen; defining, for each reprocessing modality, a first cross-contamination probability factor representing the probability that a problematic pathogen is transferred from a first medical instrument carrying a problematic pathogen to a second medical instrument not carrying the problematic pathogen while the first and second medical instruments share the same reprocessing modality; and combining the first indicators, the first data, the second data, and the first cross-contamination probability factors to determine, for each of the reprocessed medical instruments, a contamination probability that the respective medical instrument carries the problematic pathogen. Further provided is a medical instrument provisioning system.

Described herein is an endoscope with a main body and an elongate shaft,wherein the endoscope comprises an internal memory storage element, a controller, and a communication interface, the controller being configured to receive, through the communication interface, one or more of usage-related data, reprocessing-related data, and error-related data, and to store such data on the memory storage element; andthe controller further being configured to read, from the memory storage element, such one or more of usage-related data, reprocessing-related data, and error-related data, and to output the data through the communication interface.Also provided are endoscope maintenance systems and methods for communicating data therein.

The invention relates to a reprocessing device for reprocessing a medical instrument and to a method for reprocessing a medical instrument and to a use of a reprocessing device. The reprocessing device (1) comprises a reprocessing chamber (10) for receiving a medical instrument. The reprocessing chamber comprises an inlet port (12) and an outlet port (11). A circulation line system (20) comprises a first connecting line end (21) and a second connecting line end (22). The first connecting line end is connected to the outlet port (11) of the reprocessing chamber and the second connecting line end is connected to the inlet port (12) of the reprocessing chamber. A circulation device (30) is connected to a circulation line (25) of the circulation line system and adapted to circulate a flushing fluid through the circulation line system from the outlet port (11) of the reprocessing chamber to the inlet port (12) of the reprocessing chamber. A sampling device (40) for removing a sample of flushing fluid from the circulation line system (20) is connected to a circulation line (25) of the circulation line system. The sampling device comprises a valve arrangement (41) that is connected to the circulation line system (20) for removing flushing fluid from the circulation line system.
