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.

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).

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).
