- Endoscopic camera module Endoscopy systems, endoscope device, endoscope sleeve, extracorporeal module holder, medical imaging system, method for operating a medical imaging system
- the present invention relates to an endoscopic camera module, endoscopy systems, an endoscope device, an endoscope sleeve, an extracorporeal module holder, a medical imaging system and a method for operating a medical imaging system.
- endoscopic cameras In endoscopic diagnosis and therapy, particularly in minimally invasive surgery (MIS), endoscopic cameras have been used for decades in conjunction with endoscopes for image acquisition and documentation.
- these cameras can be designed as video cameras, allowing, for example, a user to monitor a procedure on a monitor essentially in real time.
- endoscopic cameras are attached to the proximal eyepieces of endoscopes via coupling adapters, such as those described in US 4,066,330 A, US 5,205,280 A, and US 5,591,119 A.
- Such coupling adapters are either permanently integrated or detachably connected to the camera housing.
- the coupling adapters typically include an imaging optic that projects an endoscopic image of an object area onto an image sensor of the camera. It is known that such imaging optics can be designed to be focusable and/or zoomable by means of axial displacement mechanisms of individual lenses.
- clamping devices and/or tensioning devices exist for coupling adapters that implement a fixed, detachable connection to the eyepiece; see, for example, US 4,066,330 A or US 5,205,280 A.
- Corresponding counterparts on the coupling adapter also exist for endoscopes without an eyepiece, but which allow a different type of proximal connection, for example, including a C-mount thread.
- the cameras are either sterilized and/or sealed together with at least part of the coupling adapter using a 2023P00163EP - 2 - KARL STORZ SE & Co. KG protected by a tubular sterile coating, a so-called sterile coating.
- these video endoscopes achieve at least substantially equivalent image resolution and/or image quality compared to optical endoscope image transmission along the endoscope shaft, e.g., via rod lenses or optical fibers, so that optical endoscope image transmission no longer offers any advantages in terms of image resolution and/or quality.
- Stereo endoscopes with two cameras in the distal end section already exist, each comprising a 4K image sensor and imaging optics with a large opening angle comparable to standard endoscopes.
- High-resolution endoscopes mostly rigid, optical endoscopes with high-resolution proximal cameras and, mostly flexible, video endoscopes with a camera in the distal end section are used.
- These thin-caliber, flexible video endoscopes are increasingly offered as single-use products and used clinically. Different versions of these video endoscopes can generally be controlled by a single camera control unit, a control unit, and/or a camera processing unit. These flexible, single-use endoscopes with a distal camera are disposed of after a single use and cannot be reused. 2023P00163EP - 3 - KARL STORZ SE & Co. KG will be used for further purposes. Market estimates for disposable endoscopes predict growth from approximately US$1.2 billion in 2022 to approximately US$3.0 billion in 2028, despite the disadvantages of disposable products such as high costs, high waste volume and high resource consumption.
- the inventors recognized the desirability of cost-efficiency and resource reduction, particularly with regard to energy-intensive components manufactured for disposable products.
- Image sensors and/or cameras typically represent a cost-, resource-, and/or energy-intensive component of a disposable video endoscope.
- the application is based on the understanding that cameras in disposable video endoscopes used intracorporeally now offer very high image quality. This quality is now comparable to that of a camera used extracorporeally on a proximal eyepiece.
- the invention aims to enable efficient operation of endoscopes, particularly with regard to resource and/or energy use and/or costs.

- the endoscopic camera module is designed for optional intracorporeal or extracorporeal use and comprises a module head and a module connector, in particular an elongated one, which is configured for data transmission coupling with a control unit and which, in particular 2023P00163EP - 4 - KARL STORZ SE & Co. KG is designed in sections and is flexible.
- the module head comprises an image acquisition device that includes at least one optical element and at least one image acquisition sensor downstream of the optical element, which are configured to acquire image information of an object area and to generate image data.
- the module head further comprises a housing that encloses the image acquisition device, in particular at least the image acquisition sensors, and a coupling mechanism configured to couple the module head to an intracorporeally insertable module holder, in particular arranged on a distal section of an endoscope shaft, in an intracorporeal configuration in which the endoscopic camera module can be used intracorporeally, and further configured to couple the module head to an extracorporeal module holder, in particular arranged on a proximal section of an endoscope shaft, in particular an endoscope device, in an extracorporeal configuration in which the endoscopic camera module can be used extracorporeally.
- the module head has a tapered section within which the coupling mechanism is arranged such that it does not contribute to the cross-section of the module head.
- the present invention provides for the provision of an endoscopy system.
- the endoscopy system comprises an endoscopic camera module according to the invention, comprising a module head including a coupling mechanism, and an endoscope device.
- the endoscope device comprises an endoscope shaft having a distal section and a proximal section, and an intracorporeally insertable module holder arranged on the distal section of the endoscope shaft, wherein the coupling mechanism is configured to couple the module head to the intracorporeally insertable module holder in an intracorporeal configuration in which the endoscopic camera module can be used intracorporeally.
- the invention also relates to an endoscope device for an endoscopy system according to the invention, in particular with the features described in the context of the endoscopy system comprising the intracorporeally insertable module holder.
- the invention also relates to an endoscope sleeve for an endoscopy system according to the invention, in particular with the features described in the context of the endoscopy system comprising the intracorporeally insertable module holder. 2023P00163EP - 5 - KARL STORZ SE & Co. KG
- the present invention provides for the provision of an endoscopy system.
- the endoscopy system comprises an endoscopic camera module according to the invention, comprising a module head including a coupling mechanism, and an endoscope device.
- the endoscope device comprises an endoscope shaft having a distal section and a proximal section, and an extracorporeal module holder which is arranged, in particular can be arranged, on the proximal section of the endoscope shaft, wherein the coupling mechanism is configured to couple the module head to the extracorporeal module holder in an extracorporeal configuration in which the endoscopic camera module can be used extracorporeally.

- the present invention provides a method for operating a medical imaging system.

KG
- the camera module can be used flexibly and/or selectively both intracorporeally and extracorporeally. This means that the camera module can be used in conjunction with a "tip-chip endoscope" and a conventional rigid endoscope with endoscope image transmission along the endoscope shaft. Specifically, the camera module can form the camera for the "tip-chip endoscope," or, together with the endoscope device, it can form the endoscopy system that can be used like a "tip-chip endoscope.” After use with the endoscopy system and/or intracorporeally, the camera module can optionally be used extracorporeally and/or with a different endoscope device.
- the camera module can be coupled to the extracorporeal module holder and/or to the second endoscope shaft. This allows the camera module to function as an extracorporeal camera for a video endoscope.
- the same camera module can therefore be used for different types of endoscopes.
- the same coupling mechanism can always be used for attaching the camera module to one of the endoscope devices.
- This mechanism is positioned on the camera module in such a way that it does not contribute to the cross-section of the module head. This makes the camera module suitable for use with thin-diameter endoscope shafts and/or enables the provision of a thin-diameter endoscopy system.
- the camera module in combination with the intracorporeally insertable module holder, could be pre-assembled, pre-sterilized, and/or packaged together as a single-use product.
- the endoscope device with the intracorporeally insertable module holder can be disposed of.
- the camera module can be reused. For this purpose, it can be cleaned and/or sterilized or reprocessed.
- extracorporeal use with a sterile covering is conceivable. This allows the image sensor and/or other elements such as lenses and/or the like of the camera module, which are also typically included in a disposable endoscope, to be reused multiple times.
- the invention is based on the understanding that a camera module can be easily and/or efficiently reprocessed for extracorporeal use.
- the effort required to reuse the camera module for intracorporeal use may be considerably greater than for extracorporeal use. Therefore, a camera module used once intracorporeally can be efficiently used multiple times extracorporeally. This reusability of the camera module can save costs for the user and/or operator.
- the same camera control unit can be used for both intracorporeal and extracorporeal applications, which can lead to further cost savings.
- the endoscopic camera module can be designed as a self-contained, handleable unit.

This can mean that the camera module can be inserted into a cavity via a trachea, esophagus, incision, and/or the like, and/or is movable within cavities of a patient, particularly in the intracorporeal configuration.
- a maximum diameter of the module head can define a maximum diameter of the camera module.
- a thin-caliber endoscope or endoscopy system can be provided.
- intracorporeal or extracorporeal can mean that the camera module can be operated in either an intracorporeal or extracorporeal configuration, depending on requirements, sterilization status, and/or other factors.
- the camera module can therefore be operated either inside or outside a cavity to image an endoscopic area.
- Intraporeal can mean that the camera module is at least partially inserted into a cavity for imaging.
- the module head can be inserted, at least substantially, into the cavity.
