Description

[0001] Method of operating a medical surveillance system for handling and / or surveying objects in a medical operation room and a Surveillance System with enhanced functionality for application in a medical operation room and a corresponding apparatus.

[0002] The invention relates to a method of operating a medical surveillance system for handling and / or surveilling at least one object in a medical operation room, wherein in the at least one object being surgical instruments and / or animal or human tissue in a storage box, to a surveillance system and a method for handling instruments and / or animal or human tissue, to a method of retrieving a data set, and to a corresponding apparatus.

[0003] Human or animal tissue is often extracted from a patient during a medical operation. While in some cases human tissue is just removed, there are several occasions where a human tissue should be stored, analyzed and / or should be transported to another entity, for example a pathology department or laboratory, in order to perform diagnostic processes like a search for cancer.

[0004] It is an object of a first aspect of the invention to provide methods and a corresponding apparatus improving handling of animal or human tissue. This is achieved by methods and an apparatus according to the respective main claims. Preferred embodiments can, for example, be derived from the respective dependent claims. The content of the claims is made a content of the description by explicit reference.

[0005] The invention relates to a method of operating a medical surveillance system for handling and / or surveilling at least one object in a medical operation room, wherein in the at least one object being surgical instruments and / or animal or human tissue located in a storage box, the method comprising the following steps:

[0006] - placing the at least one object on a tray, wherein the tray is a screen comprising one or more lighting elements,

[0007] - taking at least a first picture of the at least one object on the tray at a first point in time, -identifying the at least one object in the first picture,

[0008] - generating at least a first data set comprising data relating to the at least one object identified in the at least first picture. With this method, it will be much easier, faster and less expensive to conduct the method of survei II ing objects in a medical environment. The tray - normally being a table plate of a solid material - now not only holds the at least one object but serves as an illumination source for the at least one object. Consequently, additional lighting sources, like lamps or the like, can be avoided and the method may be carried out faster and less expensive.

[0009] The invention also relates to a method of handling animal or human tissue. The method comprises the following steps: providing the tissue in a storage box, the storage box having at least an upper window through which the tissue in the storage box is observable, and the storage box having an identifier storing and / or representing an identifier value, putting the storage box on a tray, so that the upper window faces upwards, taking a picture of the storage box, and generating a data set comprising at least the picture, or a part of the picture, and the identifier value.

[0010] With this method, handling of animal or human tissue can be simplified and can be provided with greater security. The data set comprises comprehensive information about the tissue and / or the storage box and can be used in order to further handle the tissue. This can especially be used in order to securely identify the box and / or the tissue contained in the storage box at later processing steps, for example when analyzing the tissue at an external entity. The data set can be used in order to securely identify that the tissue has not been inadvertently or even deliberately exchanged. The identifier securely identifies and / or represents the storage box, the storage box’s digital identification, and / or tissue information, and thus the tissue being enclosed in the storage box.

[0011] The storage box may especially be a vessel that is specifically prepared in order to store a tissue. The tissue may especially be extracted from a patient, be it a human or an animal, during a medical operation. Such tissue can, for example, be indicative of a specific medical condition, for example cancer. In many cases it is necessary to determine if such a medical condition is present. This can be done while the storage box is on the tray, or it can be done afterwards, especially after removing the storage box from the tray and even in another entity. Especially, the storage box may be lockable and / or sealable, so that an unauthorized removal of the tissue can be prevented. For example, there may be a locking mechanism at the storage box that can only be operated with a specific code or a specific key. The upper window allows medical personnel to directly view the tissue stored in the storage box. Especially, a picture can be taken by a camera positioned above the tray and / or the storage box. This picture can be used later on in order to identify the tissue or to cross-check if the correct tissue is to be analyzed. Especially, an operator at an external entity can use the picture taken while the storage box was on the tray in order to see if changes have happened to the tissue and / or in order to verify that the correct tissue will be analyzed. For example, the storage box may be made of plastic. The upper window and / or a lower window may be made of a transparent material, especially of glass or of transparent plastic.

[0012] Possible embodiments of the identifier will be discussed below. Especially, the identifier can be embodied such that it may be read out in an automatic manner. For example, an RIFD tag and / or a QR code can be used. It may store an identifier value itself, so that the identifier value can be easily retrieved just by reading out the identifier. It may also represent an identifier value, so that the identifier value can be derived from any information contained in the identifier. Typically, the identifier is fixedly connected with the storage box, so that it cannot be removed from the storage box without destroying the storage box. The data set may especially be generated and then stored, for example in a local storage and / or in an external server. This may allow to give access to the data set to anyone who needs it, but also to control access to the data set.

[0013] If only a part of the picture is used to generate the data set, this part may especially comprise the tissue.

[0014] Especially, the storage box may comprise a data storage, being embodied as an internal data storage or a reference to an external data storage. The data storage may especially be combined with the storage box such that it cannot be removed easily and / or cannot be removed without destroying the storage box. If it is an internal data storage, the storage box can electronically store data in a specific element. If it is a reference to an external data storage, the data storage can provide any reference so that information in an external data storage can be accessed by using this reference. For example, such a data storage can be used as an identifier.

[0015] Especially, the identifier value and / or a signature may be stored in the data storage. The identifier value and / or a signature may be read out from the data storage for generating the data set. Thus, the data storage may be used in order to store the identifier value and / or a signature.

[0016] In the context of stored data, a value may especially refer to the actual content or information stored. Thus, the identifier value may especially be a specific numeric or alphanumeric value that can be used to specifically identify a storage box. A signature may be a unique identifier or verification code associated with the data to ensure integrity or authenticity. A signature can be a digital signature in the cases of digital data. For example, it may be created using cryptographic techniques.

[0017] Especially, the storage box may comprise a wireless access interface for accessing the data storage. This wireless access interface may be used in order to read out data from the data storage. The data storage may comprise and / or may be accessed using an RFID tag, an NFC tag, or one or more magnetic stripes for wireless access. This can be used in order to rely on widely available technology to access the data stored in the data storage. However, also other means of accessing the data can be used.

[0018] The method may further comprise writing information relating to the tissue in the data storage. Thus, the data storage which is a part of the storage box can be used in order to store information relating to the tissue. For example, such information may comprise information relating to the patient from whom the tissue was extracted, the date at which it was extracted, any known or suspected medical condition, any requirements relating to cooling or other storage conditions, or any other information relating to the tissue.

[0019] The information relating to the tissue can also relate to the corresponding medical procedure. In principle, it is also possible to write audio information in the data storage. With regard to audio information, reference is made to the statements given further below. Especially, the method may further comprise a step of writing the data set in a central server. The central server may especially be a server storing data and being accessible by entities that in any way handle the tissue contained in the storage box. For example, the central server may be used in order to exchange information between a medical facility extracting the tissue and an analyzing facility doing analyzing steps like searching for cancer. Especially, the method may further comprise a step of recording audio and / or video data using a microphone and / or camera, wherein the data set also comprises the audio and / or video data. Thus, a medical practitioner can produce audio data, which is an easy means in order to securely record information relating to the tissue and / or related information for example regarding further analyzing steps that need to be performed.

[0020] In principle, the data set and / or the picture may also be stored in the data storage.

[0021] The tray may illuminate the tissue through a lower window of the storage box while the picture is taken. This may be used in order to improve lighting conditions when taking the picture. The illumination may be made, for example, by using a display functionality of the tray and / or by using specific lamps. The illumination may also be made with specific light, for example ultraviolet light, in order to induce a luminescence of the tissue, which can be used in order to detect specific medical conditions.

[0022] Especially, the tissue may be positioned between the lower window and the upper window. This allows illumination through one of the windows and taking a picture through the other window. The upper window may especially be positioned opposite the lower window. Especially, the upper window may be parallel to the lower window.

[0023] Especially, the tray may illuminate the tissue with multispectral light and / or with ultraviolet light and / or with infrared light and / or with visible light and / or with a light inducing fluorescence in the tissue. This can be used in order to better view the tissue and / or in order to detect specific medical conditions. The light may not only come from the tray, but also from other light sources, for example from a lamp or other light source being positioned above the storage box. Especially, the identifier and / or a signature may be embodied as optical information and / or as QR code containing the identifier value. Such optical information can, for example, be read using a camera and / or image recognition.

[0024] The method may further comprise projecting or displaying the picture of the storage box or of the tissue on the tray and / or on a screen. For example, the same tray may be used for this purpose on which the storage box stands while taking a picture. Alternatively or additionally, another screen, for example a vertical screen, can be used for this purpose. This can immediately give a visual feedback to medical practitioners having taken the tissue out of a patient, so that they can, for example, view the tissue with high resolution and can detect medical conditions instantaneously. For example, medical practitioners may see fluorescence in the picture which would not be easily visible by directly viewing the tissue, because a camera taking the picture may be adapted to specifically record wavelengths in which such fluorescence is to be expected. Such wavelengths may also be arranged outside visible light. The picture of the storage box may be taken as a picture of the tray. Alternatively, the picture of the tissue may be extracted from the picture of the storage box.

[0025] The method may further comprise projecting or displaying information relating to the tissue on the tray and / or on a screen. Such information may, for example, be information that was retrieved automatically from the tissue, for example by image recognition, or may relate to a patient or to a suspected medical condition. This may also help medical practitioners during a medical operation.

[0026] Especially, the projecting or displaying the picture or information may be done immediately after taking the picture and / or while the storage box is placed on the tray for taking the picture.

[0027] Especially, a fluorescence camera may be used for taking a picture. Such a fluorescence camera may be used in order to detect fluorescence light emitted by a fluorescence agent accumulated and / or absorbed by the tissue, especially with wavelengths that would not be visible with a human eye. The fluorescence agent may be some substance which the patient drinks or gets injected before taking out the tissue from the patient. For example, Aminolevulinic acid can be used as such substance. The fluorescence camera is typically adapted in order to detect light emitted by the fluorescence agent. The method may also further comprise identifying a medical condition in the tissue by applying image recognition on the picture and / or by doing a laser detection on the tissue and / or by doing a temperature detection on the tissue. The laser detection may use a separate laser scanner which may, for example, scan the surface of the tissue. The temperature detection may be done using a temperature sensor and / or by doing an infrared analysis. For example, artificial intelligence and / or a learning process may be used for image recognition.

[0028] The invention relates further to a method for retrieving a data set relating to human or animal tissue stored in a storage box, the method comprising the following steps: reading out an identifier value and / or a signature from an identifier of the storage box, and retrieving the data set based on the identifier value.

[0029] This allows handling the tissue in the storage box, especially as described further above, and then simply reading out the identifier value from the storage box and using this identifier value in order to retrieve the data set. Especially, the data set may be stored on a central server. Reference is made to the corresponding statements given above. Especially, the data set can have been generated with a method as described further above. With regard to this method, all variations and embodiments as described can be used. Thus, it is especially possible to generate a data set with the method described herein and to use it with a method described herein, so that it is easy to store information related to animal or human tissue stored in a box on a central server, where it can be accessed by authorized personnel, and to retrieve this information after having transported the storage box with the tissue in it to another entity, where the information may be easily retrieved and may be used for doing further analysis steps.

[0030] Especially, the data set being retrieved may have been taken while illuminating the tissue through a lower window of the storage box. This increases the quality of the data set.

[0031] The invention relates further to an apparatus for handling animal or human tissue. The apparatus may comprise a horizontal tray for holding a storage box. It may comprise an optical capture system and / or a camera viewing the tray. Especially, an optical capture system can be embodied as a camera. The apparatus may further comprise a control unit being configured for performing data processing steps of a method as disclosed herein. With regard to the method, all embodiments and variations as disclosed herein can be applied. Such an apparatus allows for easily and securely handling animal or human tissue, especially for storing and providing information as already described above and for assisting medical practitioners. Especially, the tray may be exactly horizontal. Alternatively, it may be tilted, for example by a few degrees.

[0032] Especially, the tray may be a display screen, or an OLED screen. The tray may comprise one or more lighting elements. These may especially be used in order to illuminate the tissue. The apparatus may comprise a projection apparatus for projecting of an image on the tray. This image can, for example, contain the picture of the tissue, and / or may contain additional information. Especially, the apparatus may comprise a screen being separate from the tray. The screen may be configured to display information. Especially, such a screen may be a vertical screen.

[0033] Especially, the tray may be rollable. The apparatus may comprise a roll for reeling and unrolling the tray. This may allow unrolling the tray if it is used, and may allow storing it in order to reduce required space when it is not in use.

[0034] Especially, the apparatus may comprise a set of rolls to move the apparatus on a ground. The rolls may also be denoted as rollers and / or wheels. Alternatively, the apparatus may generally stand fixedly on a ground.

[0035] The apparatus may further comprise an extendable structure, wherein the camera or another camera may be fixed to the structure in order to be adjustable with respect to the rest of the apparatus. This can be used in order to position the camera at a suitable position if used, and to stow it with minimum space requirements if not used. Especially, the camera can be mounted to a flexible and / or tiltable camera mounting. Especially, the camera, or at least one camera, may be a fluorescence camera. This may allow the camera to detect fluorescence emission from and / or fluorescence absorption by the tissue, especially by accumulation of a fluorescence agent, which may, for example, be used in order to detect a medical condition. Especially, suspicious and resected tissue samples may be monitored and videodocumented during their resection with a camera from an extendable arm of an apparatus or cart. Suspicious and resected tissue samples may be placed inside a special specimen cup and / or storage box. The specimen cup and / or storage box may be equipped with a unique identification element, for example a QR code or an RFID chip. The specimen cup and / or storage box may be placed on top of a rollable and / or extendible OLED screen that also provides a life camera image next to the cup, e.g., from a regular camera, for example for photo or video documentation, or a fluorescence camera, also with the option for photo or video documentation. The regular fluorescence camera may be placed above the OLED screen. An OLED screen may provide sections and / or zones with protocol data and meta information about tissue sample, and also interaction zones, for example keyboard or feature buttons, for example a “start recording button”. A boundary box may surround the tissue specimen cup and / or storage box. Interactive tactile and gesture commands may be used in order to adapt such boundary boxes or otherwise for performing control operations.

[0036] In the following, a further invention aspect of the invention will be described. These inventive aspects are independent, but can be combined with other aspects disclosed herein, especially in order to form a surveillance system of a medical operation room with enhanced functionality and / or in order to provide corresponding methods.

[0037] This aspect of the invention relates to a method for surveil ling surgical instruments and to a corresponding apparatus.

[0038] Surgical instruments like scalpels, scissors or sponges are typically used in medical operation of a patient. It is widely known that even when medical practitioners exercise great caution during operation, there are a plurality of incidents each year where surgical instruments are left in a patient. Such a forgotten surgical instrument may lead to severe medical conditions and even death after the medical operation if it is not noticed in due time. It is an object of the invention to provide a method and a corresponding apparatus increasing security when performing a medical operation. This is achieved by a method and an apparatus as disclosed herein.

[0039] The invention relates to a method of survei II ing surgical instruments. The method comprises the following steps: taking a first picture of a tray at a first point in time, identifying one or more surgical instruments in the first picture and generating a first data set comprising data relating to the surgical instruments identified in the first picture, taking a second picture of the tray at a second point in time, wherein the second point in time is after the first point in time, identifying one or more surgical instruments in the second picture and generating a second data set comprising data relating to the surgical instruments identified in the second picture, performing a comparison between the first data set and the second data set, and issuing a result based on the comparison.

[0040] With such a method, it is possible to automatically check if surgical instruments that were present on the tray at a first point in time are also present at a second point in time. If a medical operation is performed between the first point in time and the second point in time, the automatic identifying of the surgical instruments and the comparison between the first data set and the second data set may reveal if any surgical instrument is missing, and if such a surgical instrument is in fact missing, it is possible that it has been forgotten in the patient. It is thus possible to automatically inform medical practitioners that a surgical instrument is missing before the patient is transported out of the operation room. The risk of leaving a surgical instrument in a patient inadvertently and the corresponding medical problems for the patient can thus efficiently be avoided. The first data set may also be updated between the two points in time, so that it can be taken into account if, for example, a surgical instrument was added to or was removed from a set of surgical instruments used for operation.

[0041] The method may especially be used in an operation room comprising an apparatus as disclosed herein, the apparatus especially comprising a tray, an optical capture system and / or a camera, and a control unit. Reference is made to the description given elsewhere herein.

[0042] A surgical instrument may, for example, be a scalpel, a knife, a scissor, a sponge, a swab, or a forceps. However, this list is non-exhaustive. In principle, every instrument that is used during an operation of a patient, be it a human or an animal, can be surveilled by the method disclosed herein.

[0043] A picture may especially be taken by a camera. The pictures may be taken separately. Alternatively, a video stream can be recorded, and the pictures may be taken out of the video stream. In principle, a picture represents the state of the tray at a certain point in time. It does not matter how many further pictures are taken before the first point in time, between the first point in time and the second point in time, or after the second point in time.

[0044] The tray may especially be a suitable surface for providing the surgical instruments. For example, the surgical instruments may be provided to medical practitioners before an operation, and there the first picture may be taken. After the operation, the medical practitioners put the surgical instruments back on the tray, and then the second picture is taken. The tray may thus also function as a temporary storing place for surgical instruments.

[0045] The identifying of one or more surgical instruments may especially be performed by optical recognition. Also other means such as laser scanning may be used. The first data set comprises data that is typically suitable in order to identify the surgical instruments. Especially, the data set may be generated such that a data set is unique for a certain combination of identified surgical instruments. When a comparison between the first data set and the second data set is performed, it is especially checked if some surgical instrument that has been identified in the first picture is missing in the second picture. If this is the case, the result may indicate this fact and may thus alarm the medical practitioners.

[0046] Instead of using just one picture as the first picture or second picture, there may also be used several pictures in combination. For example, these pictures may be combined to a combined picture and then the identification may be based on this combined picture. Alternatively, there may be several pictures, which may, for example, be taken in close proximity in time, and the identifying of surgical instruments may be performed on each of the pictures, so that a possible error can be detected by the fact that different surgical instruments have been identified in these pictures.

[0047] The method may preferably further comprise issuing a clearance notice in response to identifying the surgical instruments in the first picture. Especially, such a clearance notice may be issued immediately after the first point in time. The clearance notice may especially signal medical practitioners that the surgical instruments placed on the tray are “ready to use”. The clearance notice may, for example, be given by a light, a visual signal, a sound signal, and / or a visual display. This gives the medical practitioners the security that all medical instruments have been identified and that they can safely start with the medical operation.

[0048] Especially, the identifying of one or more surgical instruments in the first picture may comprise determining a respective type, number, and / or shape of the surgical instruments. The first data set may especially comprise determined types, numbers, and / or shapes. This allows for a further detailed identification of surgical instruments. Determining a respective type may simplify identifying the surgical instrument and comparison between the pictures. The type may also be used in order to check if correct instruments are placed on the tray. This may, for example, be compared to stored data revealing required types of surgical instruments for a certain type of medical operation. The number of surgical instruments may especially reveal how many surgical instruments of a specific type are present. For example, the data set may comprise the fact that surgical instruments of a certain type are present, and may in addition comprise the number of such surgical instruments. For example, instead of storing six identical surgical instruments in the data set, only the type and the number “6” may be stored. The shape may also be used in order to identify the surgical instrument. In addition, the shape of a surgical instrument may for example be used in order to determine if it is in a certain state, for example in the case of a scissor having two parts being movable relative to each other. Putting such information in the first data set may increase security when being compared to the second data set, which may, preferably, also contain such information. Especially, the clearance notice may only be issued if all types, numbers, and / or shapes or all identified surgical instruments have been determined. Alternatively, the clearance notice may only be issued if the respective types, numbers, and / or shapes of some of the identified surgical instruments and / or of identified surgical instruments of a certain type or of several certain types have been determined. Thus, the clearance notice not only signals that surgical instruments have been identified, but also that they have been correctly identified regarding their type, number, and / or shape, which even increases security.

[0049] If for a surgical instrument its type, number, and / or shape could not be determined, a message and / or a visual notification and / or an audio notification may be generated identifying the surgical instrument. This can especially inform a user that something has been identified in the first picture, which could however not be identified to the necessary extend in order to use the gathered information for tracking. The user may then, for example, enter missing information manually, especially as described in the following.

[0050] The method may further comprise manually inputting and / or registering a surgical instrument and / or a type, number and / or shape into the first data set. This may be used in order to add surgical instruments and / or corresponding information, especially if the surgical instrument or its information was not recognized correctly, or if the surgical instrument was not in the first picture, for example due to lack of space for the surgical instrument. For manually inputting and / or registering, a touch screen, for example a touch screen functionality of the tray, or any other input means may be used.

[0051] If it is recognized between taking the first picture and the second picture that a surgical instrument was disposed, the surgical instrument may be removed from the first data set. A disposal may, for example, be made using a pass-through opening or a transfer unit as disclosed elsewhere herein. A disposal may especially mean that the respective surgical instrument is taken out of a set that is used for operation. Such a disposal may be detected automatically, especially as disclosed elsewhere herein. If the surgical instrument is identified by type and number, a detected disposal of one such surgical instrument may lead to the number being decreased by one. If it is recognized between taking the first picture and the second picture that a surgical instrument is added, the surgical instrument and / or its type, number and / or shape may be added to the first data set. An addition of a surgical instrument may, for example, be made using a pass-through opening or a transfer unit as disclosed elsewhere herein. An addition of a surgical instrument may especially mean that the respective surgical instrument is added to a set that is used for operation. Such an addition may be detected automatically, especially as disclosed elsewhere herein. If the surgical instrument is identified by type and number, a detected addition of one such surgical instrument may lead to the number being increased by one.

[0052] Especially, the clearance notice may be given as a light signal, an optical signal, and / or an acoustic signal. This may immediately and easily signal medical practitioners that they can start with a medical operation. For example, a light, an acoustic emitter, and / or a display device may be used for issuing the clearance notice.

[0053] Especially, the result may be either a positive signal or a negative signal. Such a signal may be communicated to a user or users. The positive signal may especially be different from the negative signal.

[0054] Especially, the result may be a positive signal if, or only if, the first data set is identical to the second data set. Especially, the result may be a negative signal if the first data set is not identical to the second data set. Thus, a positive signal may immediately inform the medical practitioners that no surgical instrument has been forgotten in the patient.

[0055] Should the result be a negative signal, they may immediately be alarmed to search for a possibly lost instrument. Especially, the way of signaling the result may indicate if it is a positive signal or a negative signal, for example by using different colors, different objects, or different sounds.

[0056] The result may be a positive signal if, or only if, the second data set includes at least all instruments of the first data set. This means that all instruments that are present in the first data set are also present in the second data set, even if one or more additional instruments may be present in the second data set. The first data set may be updated after its initial generation based on the first picture, especially by manual input, by automatic addition or automatic removal of an instrument from the data set, especially as described above. Thus, when the first data set is compared with the second data set, the first data set may already more accurately reflect the surgical instruments that should be present in order to ensure that no surgical instrument nor any registered object from the first data set was forgotten in the patient and / or missing during the checkout process.

[0057] Especially, the result may be a negative signal if, or only if, it is determined that one or more surgical instruments present in the first data set are not present in the second data set. This is a clear indication that some of the surgical instruments that have possibly been used during the medical operation may have been lost in the patient.

[0058] The result may be a negative signal if, or only if, the second data set does not include at least one instrument of the first data set. This means that it is possible that a surgical instrument was forgotten in the patient.

[0059] For example, the result may be signaled on a vertical screen. In this regard, the difference between the first data set and the second data set may be shown, for example in an itemized list. This may be shown on the vertical screen or on a pop-up display. Alternatively, also the tray may be used for such signaling.

[0060] Especially, a graphical icon may be displayed on the tray and / or on at least one screen for each surgical instrument present in the first data set, but not present in the second data set. For example, such a graphical icon may be an empty boundary box, or a miniaturized icon, a notification icon, a simplified and / or miniaturized boundary box, or a box in an alternative style. Especially, such a graphical icon may be smaller than a boundary box around a surgical instrument, especially in order to save space on the tray.

[0061] Especially, the tray may be embodied as a digital display in order to show information. Alternatively or additionally, a projection apparatus may be used in order to project an image on the tray. This allows displaying information on the tray. Especially, the identifying of one or more surgical instruments in the second picture may comprise determining a respective type, number, and / or shape of the surgical instruments. The second data set may especially comprise determined types, numbers, and / or shapes. Thus, it is possible to include also this information in the second data set, and especially using this data for comparison between the two data sets.

[0062] Especially, it may be implemented that identity between the first data set and the second data set is only determined if the types, numbers, and / or shapes of all identified surgical instruments, or of all identified surgical instruments of which a respective type, number, and / or shape was determined, are identical. This may give additional security, as specific data regarding types, numbers, and / or shapes of the surgical instruments are also used in order to ensure that no surgical instrument has been forgotten in the patient during operation.

[0063] Especially, it may be implemented that a surgical instrument in the first data set and a surgical instrument in the second data set are only determined to be the same if type, number, and / or shape of the surgical instrument are identical. Such a check may especially be done if such information is available. Especially, if a surgical instrument is detected which seems to be identical in the first data set and the second data set, the additional check regarding type, number, and / or shape may be performed and only if identity in this information is also determined, it is determined that the surgical instrument is the same in the first data set and in the second data set.

[0064] Especially, the surgical instruments and / or the types, numbers, and / or shapes may be identified and / or determined independent of their position on the tray. This may allow medical practitioners to put medical instruments at some free space on the tray and thus better utilize the available space on the tray compared to providing defined spaces for the surgical instruments. Especially, image recognition can be used to identify the instruments. Thus, the process does not rely on specific regions in order to identify the type or other properties of an instrument.

[0065] Especially, identifying one or more surgical instruments and / or determining one or more types, numbers, and / or shapes may be performed by optical recognition, image recognition, QR code recognition, and / or laser scanning. Optical recognition or image recognition may especially be done based on the pictures. For example, artificial intelligence, neural networks, and / or machine learning processes may be used for this purpose. Laser scanning may alternatively or additionally comprise identifying the shape or three-dimensional structure of a surgical instrument. QR code recognition may mean identifying a QR code that is printed on the surgical instrument. This QR code may identify the surgical instrument and its type. Especially, using such methods may allow that surgical instruments to be placed arbitrarily on the tray.

[0066] Especially, the tray may be a display screen. This may be used in order to present information on the tray. Alternatively or additionally, a projection apparatus or projection device may be used in order to display an image on the tray. The tray may especially be a horizontal display screen or a slightly tilted display screen.

[0067] Especially, information relating to one or more identified surgical instruments and / or its determined type, number, and / or shape or their determined types, numbers, and / or shapes may be displayed on the tray and / or on the display screen. Thus, additional information can be provided for medical practitioners. For example, metadata, protocol data, time stamps, and / or purpose of a surgical instrument may be provided.

[0068] Especially, display screens, be it horizontal or vertical, may not only be used for displaying information, but also as interactive user interfaces. For example, user input may be received using such screens. Especially, a tactile detection for user interaction manipulation may be performed. For example, a digital keyboard, buttons, operation elements, manipulation elements, or gesture features may be provided.

[0069] Especially, one or more lines may be displayed on the tray and / or on the display screen. Each line may fully or partially surround one or more corresponding surgical instruments. This may help medical practitioners in identifying surgical instruments. For example, lines and / or shaded lines, nebular boundaries, perforated lines, boundary elements, and / or indication elements may be used. For example, each medical instrument or some medical instruments may be surrounded by a respective boundary box. Especially, one or more fields may be displayed on the tray and / or on the display screen for putting corresponding surgical instruments on the fields. Neighboring fields may especially be delineated against each other by different colors and / or structures. This may allow orientation on the tray so that a medical practitioner easily finds a required surgical instrument. Especially, the fields may be preconfigured or user-configured.

[0070] Especially, a color and / or structure and / or shape of a respective line or field may be changed or adapted based on one or more conditions of one or more corresponding surgical instruments. This may indicate a condition of a surgical instrument to a medical practitioner. Especially, such a condition may relate to sterility, size, or a status if a surgical instrument has already been used.

[0071] Especially, a surgical operation may be performed between the first point in time and the second point in time using the surgical instruments. The method may especially be used in order to secure that no surgical instrument is forgotten in the patient during the operation and that no instrument will remain in the patient after the operation.

[0072] Especially, the first picture and the second picture may be taken of the same region. Especially, this may be the same region on the tray. Thus, the same region can be used to identify the surgical instruments before and after the operation.

[0073] Especially, the method may further comprise counting dispensed and disposed small items. The result may especially be a positive signal only if the number of dispensed small items is identical to the number of disposed small items between the first point in time and the second point in time. Especially, such an additional functionality may be used in order to track small items like sponges. There may be a special mechanism counting how many small items are dispensed and how many small items are disposed. If the number of dispensed small items and disposed small items is identical, it can be concluded that no small item has been left in the patient.

[0074] The invention relates further to an apparatus for providing surgical instruments. The apparatus may especially comprise a horizontal tray for providing surgical instruments. It may comprise an optical capture system, or camera, viewing the tray. It may further comprise a control unit being configured for performing a method as disclosed herein. With regard to the method, all embodiments and variations as disclosed herein can be applied.

[0075] Such an apparatus may especially allow an automatic tracking of surgical instruments during an operation. It may be ensured that no surgical instruments are left in the patient after the operation. The optical capture system may especially be embodied as a camera. However, it may alternatively or additionally be embodied as a laser scanner or as another system that can be used in order to identify surgical instruments.

[0076] Especially, the tray may be a display screen. The tray may especially comprise one or more lighting elements. Lighting elements can be used in order to eliminate the surgical instruments so that they can be found easily. A display screen can especially be used in order to present information.

[0077] Especially, the tray may be rollable. The apparatus may especially comprise a roll for reeling and unrolling the tray. This may be used in order to stow away the tray in case it is not used. If it is used, the tray may be unrolled and can then be used, for example, by providing a flat tray. It should be noted that such a rollable tray may be part of a single apparatus, or it may be part of another entity being in communication with the apparatus. Alternatively, a fixed tray may be used.

[0078] Especially, the apparatus may comprise a vertical screen. The control unit may especially be configured to display information relating to the surgical instruments and / or a surgical operation on the vertical screen. This may allow displaying additional information using a vertical screen, which is typically easier to read than a horizontal screen, especially in a complicated environment like an operation room and / or during a complicated operation.

[0079] Especially, the apparatus may comprise a set of rolls to move the apparatus on a ground. The rolls may also be denoted as wheels. This may be used in order to position the apparatus at an appropriate position.

[0080] The apparatus may further comprise a small item dispensing section and a small item disposing section. The control unit may be configured to count dispensed and disposed small items. The control unit may especially be configured to issue a positive signal as result only if the number of dispensed small items is identical to the number of disposed small items between the first point in time and the second point in time. This may be used to track small items like sponges as already explained above. Especially, the control unit may count small items dispensed from the dispensing section and / or small items disposed in the disposing section.

[0081] It should be noted that in such cases, when tracking small items, it may alternatively be implemented that a positive signal is also issued if more items are disposed than dispensed, because then it is expected that some small item has been disposed in the disposal section that was already present in the operation room before the first point in time. This does not lead to decreased security of the patient with regard to possible forgotten items.

[0082] The apparatus may further comprise an extendable structure, wherein the camera may be fixed to the structure in order to be adjustable with respect to the rest of the apparatus. This may allow positioning the camera at an appropriate location when in use, and may allow storing the camera without increased demand of space when not in use.

[0083] For example, a green boundary on the tray may indicate readiness of use for the surgical instruments.

[0084] It can be noted that it is a rather rare, but nevertheless well-known problem in surgical interventions that instruments and materials forgotten in patients pose a significant risk to patients. According to statistical projections, approximately 600 to 700 deaths per year in Germany can be attributed to forgetting surgical material. With this disclosure, it is provided a possibility to increase the security for patients. Within a known approach of interventions, the tray shall serve as a digital gateway for randomly shaped objects. All materials (e.g., swabs), instruments and cutlery used on the patient in the intervention area should first be placed in a sterile state on the surgical tray by the surgical assistance. There it shall be photographed with a rigidly installed optical tracking system, for example a camera, and registered subsequently by a digital program. After one digitized registration step, a signal for the object -approval must be given by the tray system signaling the clearance for use on the interventional side. The objects will then be checked. Through additionally installed screen foils, the tablet should be able to display additional functions. As soon as the interventionist no longer needs an object, he puts it back onto the tray. After its registration, the software processes a checkout step, under signaling of a readiness for object removal, allowing the assistants to remove the object. Alternatively, the interventionist can pick up the instrument from there again and continue to use it. With the help of the surgical tray, the number of objects forgotten in patients shall be reduced to zero. In addition, the tray may not only serve for the registration and tracking of instruments or tools, but even for locking (protocol writing) of implants directly before these are implanted into the patient.

[0085] In the following, a further aspect of the invention will be described. These inventive aspects are independent, but can be combined with other aspects disclosed herein, especially in order to form a medical operation room with enhanced functionality and / or in order to provide corresponding methods.

[0086] The invention relates to a separation arrangement and to a medical operation room.

[0087] Surgical or other medical operations are typically made in medical operation rooms. Depending on the type of medical operation, a certain degree of sterility has to be maintained in order to prevent infections from entering a patient’s surgical area or other open wounds, for example when using open body or open cavity surgery. This usually requires that all personnel and the entire operating theatre fulfils high sterility precaution requirements. This entails the personnel wearing protective clothing and the entire operating theater to be prepared through meticulous measures to minimize the risk of contamination.

[0088] It has been found that it would be preferable to increase the sterility quality level and / or flexibility when designing operation rooms. This is achieved by a separation arrangement, a medical operation room, and a use as disclosed herein.

[0089] The invention relates to a separation arrangement for separating a first part of a medical operation room from a second part of the operation room, the separation arrangement comprising at least one separation wall. The separation wall is configured to stand between the first part and the second part. The separation wall comprises at least one pass-through opening for passing through medical equipment between the first part and the second part.

[0090] Especially, the operation room may comprise an apparatus as described elsewhere herein, especially comprising a tray, an optical capture system and / or a camera, and a control unit. All described embodiments of the apparatus can be applied. The apparatus can especially be positioned on the first part of the operation room, typically being the sterile part where medical personnel operates a patient.

[0091] Such a separation arrangement allows for separating a medical operation room in two parts, especially with the intent to keep one of these parts sterile and the other one non- sterile, or at least less sterile compared with the first part. Especially, the first part may be a sterile part, and the second part may be a non-sterile part. In the first part, medical practitioners can directly work on a patient while maintaining a high level of sterility. In the second part, assisting personnel can operate more freely, because it is not required to keep the same standard of high sterility as in the first part. The separation arrangement allows for separating the parts against each other, so that sterility can be maintained at the patient. At the same time, it is possible to pass through medical equipment, so that medical practitioners working on a patient can be assisted by supporting staff with relaxed requirements.

[0092] The separation arrangement can especially be adapted in order to divide a room, especially a medical operation room, into two parts. This may divide the entire room into these two parts. Alternatively, the first part and second part can together extend on only a part of the medical operation room, but can nevertheless divide these two parts against each other. The separation wall can especially prevent viruses, bacteria or other hazardous substances from passing, especially from the second part to the first part and vice versa. Especially, the separation wall can be a continuous and / or noninterrupted wall besides the pass-through opening or pass-through openings. In principle, one pass-through opening can be provided. Alternatively, more than one pass-through opening, for example two or three pass-through openings, can be provided. Especially, additional equipment can be provided in the pass-through openings, for example as disclosed further below. The separation wall may especially be arranged to stand in a vertical orientation. With such an arrangement, space requirement can be reduced compared to a tilted arrangement. However, in certain cases it may be preferable to have a tilted separation wall.

[0093] Especially, the separation arrangement may comprise at least one transfer unit being arranged to pass through the pass-through opening in order to transport medical equipment to the first part and the second part. Such a transfer unit may be a special unit that assists passing through medical equipment, especially manually, semi- automatically and / or fully automatically, for example robotically and / or using a robotic arm. Especially, the transfer unit may be or may comprise a conveyor belt, a movable tray, a slide type unit, a roll conveyor, a robotic arm, and / or a robotic system. A conveyor belt may especially be a belt that may be driven manually or electrically in order to transport medical equipment. A movable tray may be a tray that is adapted to move along a certain path, which may also be operated manually or electrically. Medical equipment may be put on the tray and thus transported between the parts of the operation room. A slide type unit can comprise a slide, on which a medical equipment can be put so that gravity drives it along a given way. A roll conveyor can especially comprise a plurality of rolls, so that medical equipment can be passed between the first part and the second part, for example by exerting a certain horizontal force manually. A robotic arm or a robotic system may be used to manipulate objects, especially for grabbing or otherwise attaching them and for bringing them to another position.

[0094] Especially, the transfer unit may be electrically operable and / or manually operable. Electrical operation typically means that one or more electric motors are present that can be operated by a switch or any other control unit. Manual operation can, for example, be provided by a crank, that can be operated manually and can transfer its movement to any other entity.

[0095] Especially, the transfer unit may be curved, or may be curved with an angle of more than 10°, or may be curved by an angle of 90°, at the side of the first part and / or the side of the second part. By using a curved transfer unit, a certain path along a curve can be provided, along which medical equipment can be transported. For example, this can be used in order to provide spatial awareness and sufficient spatial extent and / or an increased shielding compared to a straight path which could interfere with the workflow of the personnel. In an alternative embodiment, however, the transfer unit may not be curved and can, for example, follow a straight path. Such a curved or non-curved path can especially define a way along which medical equipment can be passed between the two parts. It can, for example, define the extension of a conveyor belt, the path of a movable tray, the path of a slide type unit or a roll conveyor.

[0096] In principle, any orientation can be used for a curved path.

[0097] Especially, the transfer unit may comprise a mesh tray, especially an aluminum mesh tray. This may be used to temporarily store objects and / or to provide a second layer for more storage.

[0098] The separation arrangement may further comprise at least one disinfection apparatus being arranged adjacent to at least one pass-through opening and / or a transfer unit for disinfecting medical equipment passed through the pass-through opening. Such a disinfection apparatus may provide for disinfecting medical equipment while passing through an opening. For example, medical equipment provided by non-sterile supporting staff can be disinfected and thus fulfil the requirements regarding sterility. This relaxes sterility conditions outside the inner space of an operation room in which a patient is located. It is also possible to perform a disinfection at medical equipment passed from the first sterile region, because non-sterile supporting staff can be prevented from being infected by pathogens that may be emitted from a patient.

[0099] For example, the disinfection apparatus may be embodied as a radiation emitter. Especially, an ultraviolet lamp can be used. This typically eliminates pathogens on medical equipment on which ultraviolet light is applied. Alternatively or additionally, the disinfection apparatus may be embodied for spraying a liquid disinfectant. Alternatively or additionally, a heat lamp can be used in order to heat the medical equipment for sterilization.

[0100] The disinfection apparatus may be configured to produce a sound effect and / or a visual effect and / or a notice on a screen to indicate the end of a disinfection process. The separation arrangement may further comprise at least one chute being arranged to pass through at least one pass-through opening. Such a chute may especially be directed in one of the parts, so that medical equipment can be placed on the chute on the other part and will then slide through the chute in the other part. For example, the chute may be rotatable and / or tiltable. This allows to change the direction of movement due to gravity, and to adjust the exact location of the output.

[0101] Especially, the separation wall may comprise a stand for separately standing on a ground floor. Alternatively or additionally, the separation wall may comprise rollable wheels being arranged to stand and / or move the separation wall on a ground floor. Such rolls or rollable wheels can be used in order to move the separation wall in a correct position. Especially, the rollable wheels can comprise locking means so that the separation wall can be held at a correct place.

[0102] The separation wall may especially comprise a fixation arrangement for fixation to a medical table. This allows direct fixation of the separation wall to a medical table, for example a table on which a patient to be operated is situated and / or on which medical equipment is stored. Such fixation arrangement can, for example, be embodied as claws or using screws.

[0103] The separation arrangement and / or the separation wall may be configured to provide a radiation shielding against passing of X-rays and / or ionizing radiation and / or radiofrequency waves from the first part to the second part and / or from the second part to the first part. This allows a shielding against possibly hazardous radiation. For example, X-rays, ionizing radiation or radiofrequency waves can be used at a patient in one part, and medical personnel immediately surrounding the patient can, for example, be protected by personnel protective measures which they wear at their body. However, supporting personnel at another part of the operation room may not wear such protective equipment, but can be protected by using the separation arrangement. For X- ray radiation, depending on the application, typical radiations can range between 30 and 150 kVp (kilovolt peak) and 20 to 200 keV (kilo-electron volt) which are two different things even though both measure the energy level of X-ray production. Especially, the separation arrangement and / or the separation wall may meet the minimum standards of lead (Pb) thickness equivalents of 1 to 2 mm or above, an energy value of 150 keV and / or 150 kVp or above, or an RF value of 10 to 120 dB (decibels) or above. X-ray glass may contain a large amount of lead and / or barium, enabling optimum shielding against radiation from lab equipment that emits, for example, in the range of 80 to 300 kV. Such X-ray glass may be used as a material for the separation wall. For example, lead, non-lead substitute, glass, plexiglass, metal plates and / or metal meshes can be used in order to provide shielding.

[0104] The separation arrangement may further comprise at least one covering element being arranged with distance to at least one pass-through opening to cover the pass-through opening. Such a covering element may reduce exchange of radiation and / or pathogens between the parts. The covering element may especially cover, fully or partially, a pass- through opening.

[0105] Especially, the separation wall may be fully or at least partially optically transparent. This allows visual communication between personnel on both sides. Alternatively, the separation wall may be fully non-transparent.

[0106] Especially, the separation arrangement may further comprise at least one surveillance device, the surveillance device being configured to identify and / or count equipment passed through at least one pass-through opening and / or to determine sterility of equipment passed through at least one pass-through opening. Such a surveillance device may be used in order to electronically determine and store which medical devices are passed through a pass-through opening and / or in order to determine and store certain conditions like sterility. This can, for example, be used in order to help preventing that medical instruments are left in a patient. For example, the surveillance device may be embodied as a camera, an RFID reader, a laser scanner, or as an entity for reading QR codes. Consequently, RFID tags and / or QR codes may be present on medical equipment. Alternatively, or in addition, medical equipment can be detected by using image recognition and / or by using a surface recognition using the laser scanner.

[0107] Especially, the surveillance device may be configured to store information regarding equipment passed through the pass-through opening on a storage device. The surveillance device may also be configured to send information regarding equipment passed through the pass-through opening to an external entity. This allows monitoring which medical equipment has passed through the pass-through device, for example for the purpose of surveilling a stock of medical instruments, for billing, for counting, and / or for checking that no medical instrument has been left in the patient after a medical operation.

[0108] The surveillance device may comprise a camera, especially a webcam. This can be used in order to view items and thus especially to provide pictures or video streams that may be evaluated. A webcam may provide for direct streaming over the internet, allowing an evaluation electronic to be positioned remotely. The surveillance device may use artificial intelligence, e.g. a neuronal network, to identify and / or count equipment passed through the pass-through opening and / or to determine sterility of equipment passed through at least one pass-through opening.

[0109] The surveillance device may comprise a sterilization sensor, especially to keep track of the accuracy of the sterilization or sanitization of introduced instruments and sponges. In case of any failure, a specific notification and / or visual error may appear, especially it may immediately appear to inform a staff about a sterilization failure.

[0110] An automated system continuously updates the central database with the sterility status of instruments using data from QR code scans performed before and after sterilization. The system integrates with sterilization equipment to log the completion of sterilization cycles and ensures real-time monitoring for accurate status updates. Data analysis provides visual results of the sterility status, which can be displayed on the previously mentioned screen during and after surgery. This method ensures reliable and up-to- date tracking of instrument sterility throughout their lifecycle, enhancing surgical safety and efficiency.

[0111] During a surgery, data may be stored, e.g. any data that is mentioned herein. After the surgery, the data may be analyzed, for example by the staff performing the surgery, or by an automatic evaluation.

[0112] The separation arrangement may further comprise at least one tunnel structure passing through at least one pass-through opening. Such a tunnel structure may especially at least partially surround a transfer unit. The tunnel structure may especially be embodied as a tunnel, which may especially be formed along a line along which a transfer unit extends. The tunnel structure may be made of a material providing a radiation shielding against passing of X-rays and / or ionizing radiation and / or radiofrequency waves. Thus, the tunnel structure may increase radiation shielding. Reference is made to the statements given above with regard to possible implementations and materials.

[0113] Especially, the tunnel structure may be mounted rotatably, tiltable and / or be swivelmounted. Thus, the tunnel structure can be adapted to specific needs, for example to a specific direction in which a slide is currently used.

[0114] Especially, the separation arrangement may further comprise a waste container being fixed to the separation wall on the side of the second part. A guiding arrangement having a first opening on the side of the first part and a second opening on the side of the second part may also be present. The openings may be arranged and may be connected to an enclosing structure such that waste disposed in the first opening may be directed to the second opening and further to the waste container. Thus, waste can be disposed from the first side by medical personnel operating a patient and the waste may be automatically directed to a storage container on the second side. Supporting personnel on the second side can, at any time, exchange a container and further dispose the waste. This allows for easy disposal of waste and for storing waste outside a specifically clean environment.

[0115] The separation arrangement may comprise a sterilization means, especially a UVC lamp, especially for sterilization of the waste container or items disposed in the waste container. A UVC lamp may especially emit ultraviolet radiation, especially UV-C radiation. The sterilization means, especially the UVC lamp, may especially be activated if the container is closed. The sterilization means, especially the UVC lamp, may especially be positioned inside the waste container or at a cover of the waste container. This may reduce the spread of pathogens and bacteria and even keep the containers sanitized throughout the surgery. The walls, especially the walls of the waste container, can be made of specific materials, especially in order to function as an x-ray or ionizing radiation shield and / or radio frequency wave shield. The separation arrangement may further comprise attachment fixtures for sutures, swabs, medical equipment, displays and / or other entities. Thus, it can be used to store and / or make available such equipment.

[0116] Especially, the separation arrangement may comprise one further separation wall or more further separation walls. Each further separation wall may be connected with the separation wall to form a combined separation between the first part and the second part. Thus, multiple separation walls can work together in order to provide a separation, for example of a larger area than would be possible with a single separation wall. Especially, one or more further separation walls may comprise a pass-through opening and / or may be embodied according to the separation walls as disclosed herein. All disclosed embodiments and variations can be applied accordingly.

[0117] The separation arrangement may comprise one or more connection elements and preferably one or more retraction arrangements. Each connection element may be configured to be extendable at a side of the separation arrangement from a retraction arrangement and may be retractable by the retraction arrangement. This allows for providing a retraction of a connection element if it is not used, and to easily provide a connection element if it is used. This increases modularity of the separation arrangement and the separation walls. Especially, a connection element may connect neighboring separation walls. Especially, a connection arrangement may cover an entire gap between two neighboring separation walls. The connection element may also have a radiation shielding function, for example as disclosed above. The connection element, some connection elements or all connection elements may be embodied as foil, as sheet, and / or as rigid connection. Also non-retractable and / or foldable and / or rigid connection elements can be used.

[0118] A table may be arranged below, or exactly below, one, some or all pass-through openings. The table may be positioned on one side or on both sides. The table may be used for better handling of instruments and pads, for example.

[0119] One, some or all tables may have a surface made of antibacterial steel and / or with an antibacterial cover and / or with a changeable cover. Especially, the antibacterial cover may be changeable. The cover may be cut to the exact shape of the table. Similar materials or covers can be used for other tables or surfaces disclosed herein.

[0120] The separation device, especially a wall of the separation device, may comprise a screen, especially a touchscreen, especially to let a user see all the included devices from a main tray and through the wall or separation device, and / or to give the possibility to add certain devices manually in a certain surgery, preferably with details.

[0121] Locking of a device may be animated, e.g. on the screen. Details and a live view of a camera may be presented and may be switchable by a user.

[0122] The screen can also be used to visually show the precision of the sanitation or sterilization, especially throughout the surgery. For example, a chart may be used for that purpose. Sterility sensors may be used to determine sterility. For example, they may be embodied as air quality sensors, surface contamination sensors, intensity sensors measuring the intensity of radiation, especially of UVC radiation, and / or may be embodied otherwise. Also, environmental quality sensors may be used, for example temperature sensors and / or humidity sensors They may monitor temperature and humidity levels, for example. These parameters can influence bacterial growth and the effectiveness of the sterilization process.

[0123] The screen may also be used to show some or all results in real time and / or to alert the staff immediately by notifications, e.g. visually, auditory or digital. Any measurement made, especially during a surgical operation, may be recoded and / or may be visualized by different charts as the used needs or configures it.

[0124] Data of all sensors can be collected in real-time, especially by a central monitoring software. Data may be analyzed, e.g. by artificial intelligence, to detect patterns, e.g. during different surgeries. Anomalies may be detected that could indicate a breach in sterility.

[0125] Sensors may communicate by wireless communication, e.g. by Bluetooth, NFC or WiFi, with a central system. This avoids additional wiring and potential contamination points. Alternatively or additionally, wired connections to the sensors may be used. A real-time sterility monitoring system may check if all environmental parameters are within safe limits and that all instruments have been properly sterilized. By implementing such a comprehensive sterility monitoring system, the separation arrangement or a clean wall project can significantly enhance the sterility and safety of the operating room environment, thereby reducing the risk of Surgical Sight Infections and Retained Surgical Items.

[0126] The wall or separation arrangement may contain other vital options for the surgery room as well.

[0127] The invention relates further to a medical operation room. The medical operation room comprises a first part, a second part, and a separation arrangement as disclosed herein. With regard to the separation arrangement, all disclosed embodiments and variations can be applied. The separation arrangement may be arranged to separate the first part from the second part. Thus, a medical operation room with two parts can be provided. Especially, the first part may be a sterile part, and the second part may be a non-sterile part.

[0128] The invention relates further to a use of a separation arrangement as disclosed herein to separate a medical operation room into a first part and a second part. With regard to the medical operation room, all disclosed embodiments and variations can be applied.

[0129] Especially, the sterile part may comprise an operation table with a patient. The second part may comprise an area for supporting staff that has relaxed sterility requirements.

[0130] Especially, a surgical partition module that features a (transparent or non-transparent) wall or partition that separates a dedicated space of sterility (e.g., operation table with patient) from non-sterile areas (all other space outside of the sterile area) inside e.g., a surgical room may be provided. The key feature of the partition module may be to provide openings for transferring tools and / or instruments and / or devices and / or objects from the non-sterile to the sterile environment and vice versa. In addition, the partition module may provide support for / of conveyor in / out-lines for transferring tools or instruments or devices from the non-sterile to the sterile environment and vice versa. The conveyor in / out-line may include additional features to further improve sanitation, counting, monitoring, and sterility of tools and / or instruments and / or devices entering and / or exiting the sterile environment. As an additional feature, the partition contains material capable of shielding radiation from imaging systems (for example X-ray or computer tomography) or from radio therapy systems (for example tumor therapy or local radiation) sources used intraoperatively, reducing additional dosages to staff, nurses and / or surgeons, especially by shielding of ionizing radiation. Radiofrequency shielding may also or alternatively be integrated into the partition material to provide shielding properties in an arrangement with a magnetic resonance imaging system.

[0131] The partition functions as a barrier between sterile and non-sterile environments of e.g., a medical operating theater while acting as a transferring gateway of essential items from non-sterile to sterile areas. It may contain at least one opening within the partition panel for transferring essential items from non-sterile to sterile areas. A transparent feature for visibility between sterile and non-sterile environments may be provided. Fixation of partition as an attachment on a surgical table or tray or as a stand-alone mobile partition, e.g., by a partition designed as a mobile wall based on rollable wheels, may be provided. A conveyor or transfer unit in-line for consumable suture packing delivery or other transfer purposes may be provided, and there may be a new instrument addition to an initial tool kit. A conveyor or transfer unit out-line may be used for consumables (sponges of varying sizes) or specimen collection. A conveyor or transfer unit in-line may include, for example, a UV sterilization method for intermediate tools, devices, and / or consumables. The conveyor belt or transfer unit may serve for sterilization, for example through ultraviolet light, alcohol spray, alcohol dipping path, a heat lamp, or the like. The conveyor belt or transfer unit may serve for monitoring and registration purposes. The conveyor belt or transfer unit in-line and / or out-line may include for example a camera capturing or reading QR codes on intermediate tools. Also by, for example, camera installation or dedicated RFID readers, medical instruments may be detected. A wall may contain material or a composition to shield from X-ray, CT, PET radiation within the panel or partition. For example, lead, a nonlead substitute, glass or plexiglass can be used. A wall may contain material or a composition to shield from RF radiation within the panel or partition, for example using metal plates or metal meshes. A conveyor belt or transfer unit may be designed not only as a straight pathway, but also with at least one curve along its track, such as a 90° curve right behind the partition or wall. The track-shaped tunnel structure may be fabricated out of shielding (X-ray or RF shielding) material, to serve as an X-ray or RF waveguide. The opening inside the partition may be designed not only as a simple “hole”, but as a tunnel structure with e.g., at least one curve. The curved conveyor belt or transfer unit may be integrated in a curved opening tunnel structure of the same shape or track profile. The wall may include attachment fixtures of frequent consumables, for example sutures and / or swabs, especially on the non-sterile section of the partition for ease of access and swift delivery through the in-line conveyor. Also, the partition may include the attachment of digital screens or touchscreens. The separation wall may, for example, include one or more screens to display information and / or for performing input operations. It may also include a workstation, which may especially be adapted to serve as a tray for instruments or may provide for functionality such as tracking instruments, as disclosed otherwise herein.

[0132] If anything is to be detected automatically as disclosed herein, especially a You-Look- Only-Once algorithm can be used. This may be an algorithm that is very fast in detection of a specific item or a specific state.

[0134] Fig. 1 shows purely schematically an apparatus 10 according to a first embodiment of the invention. The apparatus 10 comprises a housing 20. The housing 20 stands on four wheels 25, which are placed on the bottom of the housing 20 and are used in order to easily position the housing 20 on a floor. Of the altogether four wheels 25, only three are visible in fig. 1 . The housing 20 further comprises several handles 27, which may be used in order to easily move the housing 20 on a floor.

[0135] The housing 20 comprises a tray 30. The tray 30 is embodied as a display screen, so that not only objects can be placed on the tray 30, but also information can be displayed on the tray 30. The tray 30 is embodied as a rollable tray, meaning that a roll, which is not shown in fig. 1 , is situated inside the housing 20 on which the tray 30 can be reeled and from which it can be unrolled. This allows easy stowing of the tray 30 if it is not used.

[0136] Above the tray 30, there is a vertical screen 40 attached to the housing 20. The vertical screen 40 can also be used in order to display information and can further be used in order to receive inputs by using a touchscreen functionality.

[0137] Furthermore, there is a camera 50 mounted to the housing 20, wherein the camera 50 is located immediately above the tray 30 so that it can take a picture of the tray 30. Above and besides the camera 50 is a lamp 52 that is adapted to illuminate the tray 30 and surrounding areas.

[0138] The apparatus 10 further comprises a control module which is not shown in fig. 1 .

[0139] Fig. 2 shows an apparatus 10 according to a second embodiment. The apparatus 10 comprises a further camera 53 which is secured to an extendable structure 55. The extendable structure 55 can be pulled out of the housing 20 and can also be pushed back into the housing 20, so that the position of the further camera 53 can be varied. It can be pushed out of the housing 20 for use, and it can be stored when not in use with minimal space requirements. The further camera 53 provides additional coverage of areas and can be used as a supplement to the camera 50. In an alternative implementation, the further camera 53 could be attached to an instrument table or another entity. Also in such an implementation, it can be used as if it were attached to the apparatus 10. The further camera 53 may be used in combination with the camera 50. The further camera 53 may, for example, track transfer from a table to the patient and / or backwards. The further camera 53 may, for example, be used in order to perform quality monitoring.

[0140] Fig. 3 shows a part of the apparatus 20 of fig. 2 in a sectional view. It is seen that a guiding space 57 is present inside the housing 20 for receiving the extendable structure 55. The extendable structure 55 can be linearly pulled out or pushed in, so that the position of the further camera 50 can be varied.

[0141] Fig. 4 shows a top view of the tray 30 with surgical instruments being placed on it. In detail, three surgical instruments 11 in the form of scissors, four surgical instruments 12 in the form of pipettes, one surgical instrument 13 in the form of a scalpel, and four surgical instruments 14 in the form of forceps are placed on the tray 30.

[0142] The camera 50 and / or the further camera 53 can be used in each possible embodiment to take a picture of the tray 30 with the surgical instruments 11 , 12, 13, 14 placed on it. This may be used in order to recognize the surgical instruments 11 , 12, 13, 14 with their respective type, number, and shape. A first data set may be generated comprising such information. After the recognition, respective lines 31 , 32, 33, 34 may be displayed around the respective surgical instruments 11 , 12, 13, 14 to simplify orientation on the tray 30.

[0143] In a possible implementation, the lamp 52 can comprise or can be embodied as a projection device that is possible to project an image, or images, on the tray 30. This can generally be regarded as a substitute or a supplement for embodying the tray 30 as display device. If the surgical instruments 11 , 12, 13, 14 have been detected after taking a first picture, a clearance notice may be displayed, for example on the tray 30 or on the vertical screen 40. Then, medical practitioners using the apparatus 10 are able to know that the system has recognized all surgical instruments 11 , 12, 13, 14 placed on the tray 30. They may then start an operation. After performing the medical operation, the medical practitioners may operate an input, for example using a touchscreen input on the vertical screen 40, in order to tell the control unit that the medical operation has finished. They will then place all surgical instruments 11 , 12, 13, 14 on the tray 30. Then a second picture will be taken using the camera 50. Using image recognition, the surgical instruments 11 , 12, 13, 14 will be identified again and a corresponding second data set will be generated. If the data sets are equal, meaning that the same surgical instruments 11 , 12, 13, 14 were placed on the tray 30 when taking the first picture and the second picture, a positive signal is displayed on the vertical screen 40. Otherwise, a negative signal is displayed, indicating which instrument is missing or which instruments are missing. This may help medical practitioners to be aware of the fact that some surgical instruments 11 , 12, 13, 14 is missing, which may probably be still in the patient inadvertently. They may then search for this surgical instrument 11 , 12, 13, 14, and if they do not find it besides the patient, they can, for example, open the patient again and take the surgical instrument 11 , 12, 13, 14 out of the patient.

[0144] Altogether, this significantly increases security when operating a patient.

[0145] Fig. 5 shows the tray 30 in an enlarged view with an alternative functionality compared to the functionality described with respect to fig. 4. In this case, a storage box 60 is placed on the tray 30. The storage box 60 has an upper window 61 and a lower window 62. These two windows 61 , 62 are transparent. The storage box 60 further comprises an identifier 63 in the form of a QR code, and it further comprises a data storage 64. In the storage box 60, there is positioned a human or animal tissue 65, wherein the storage box 60 is used in order to store and transport the tissue 65.

[0146] The identifier 63 stores an identifier value that can be read out in order to uniquely identify the specific storage box 60 with its tissue 65. The tray 30 may be used in order to illuminate the tissue 65 through the lower window 62 and a picture is taken through the upper window 61 . For this purpose, the already described camera 50 and / or the further camera 53 can be used. Alternatively or additionally to illumination by the tray 30, the lamp 52 can be used for that purpose.

[0147] Data relating to the tissue 65 can be stored in the data storage 64 by wireless access using an RFID tag. Thus, additional information relating to the tissue 65, for example the date of taking the tissue 65 out of a patient, can be stored on the data storage 64 and thus directly in the storage box 60.

[0148] The picture may be shown on the tray 30 in the form of a picture 66. Thus, medical practitioners can confirm that the correct picture 66 is shown. In addition, additional information 67 can be presented on the tray 30.

[0149] A data set can then be generated comprising the picture 66, the additional information 67 and the identifier value read out from the identifier 63. This data set is stored on a central server 70, which is shown schematically in fig. 5. This central server 70 can be used in order to provide the data set and the contained information to external entities, for example to a medical analysis facility. If, for example, the tissue 65 has been extracted out of a patient in a hospital and has been placed in the storage box 60 in the operation room, the information can be created and can be stored in a data set inside the hospital and can be put on the central server 70. Then, the storage box 60 with the tissue 65 in it can be transferred to the external entity, for example a lab that should analyze if a cancer is present in the tissue 65, and in this external entity the identifier value may again be read out of the identifier 63. This identifier value can immediately be used in order to retrieve the data set from the central server 70. This allows for a secure tracking and providing of information to the external entity, without the risk that the wrong tissue is analyzed and the patient gets a wrong medical result.

[0150] Fig. 6 shows an operation room 80. The operation room comprises an operation table 83 on which a patient to be operated lies.

[0151] The operation room 80 further comprises an apparatus 10 as described with reference to figs. 1 to 5. This apparatus 10 can provide the support functionality already described. The operation room 80 further comprises a table 84, to which a separation arrangement 90 is attached. The separation arrangement 90 divides the operation room 80 in a first part 81 and a second part 82. The first part 81 is a sterile part in which medical personnel 86 operates. This medical personnel is also sterile so that infection of the patient is prevented. In the second part 82, which is a non-sterile part, a non-sterile assistant 88 operates. The assistant 88 can be subject to relaxed sterility requirements and can help the medical personnel 86 with operating the patient.

[0152] The separation arrangement 90 will be further described with reference to fig. 7. The separation arrangement 90 comprises a separation wall 92. The separation wall 92 is fixed to the table 84 and provides for a separation between the first part 81 and the second part 82 of the operation room 80. The separation wall 92 comprises four pass- through openings 94, which can be used in order to provide medical equipment 85 to the medical personnel 86. The medical equipment 85 is only shown schematically here.

[0153] A respective transfer unit 96 extends through each of the pass-through openings 94. In the present case, the transfer units 96 are embodied as conveyor belts allowing staff operating in the second part 82 to put medical equipment 85 on the respective conveyor belts with which it is transported inside the first part 81 . In order to disinfect the medical equipment 85, disinfection apparatuses 97 are positioned above each conveyor belt. These include ultraviolet lamps in order to perform disinfection of medical equipment. This allows a non-sterile assistant 88 to handle the medical equipment 85, while it is sterile when used at a patient.

[0154] The separation arrangement 90 further comprises a surveillance device 98 embodied as a camera, which monitors medical equipment 85 that is transferred to the first part 81 . This allows for tracking medical equipment and for checking that no medical equipment 85 was lost in a patient. Especially, a surgical instrument 11 , 12, 13, 14 detected to be transferred to the first part may be added to a first data set, and / or a surgical instrument 11 , 12, 13, 14 detected to be transferred to the second part may be removed from a first data set. The separation wall 92 is provided with radiation shielding material, especially lead, so that ionizing radiation can be used while performing an operation of the patient without affecting the non-sterile assistant 88.

[0155] Fig. 8 shows a separation arrangement 90 according to a further embodiment. The separation arrangement 90 of fig. 8 has two separation walls 92, of which one is positioned above the other. These two separation walls 92 can also be regarded as an upper section and a lower section of one separation wall. The two separation walls 92 are fixed to a frame 93. The frame 93 stands on four rollable wheels 99, of which three are visible in fig. 8. Two pass-through openings 94 are provided in the upper separation wall 92. The separation walls 92 serve to separate two parts of an operation room so that one part can be used as a sterile part and another part can be used as a non-sterile part. The pass-through openings 94, which are in the shown embodiment not covered and are not provided with any transfer unit, can be used in order to manually pass through surgical instruments and other items between the two parts of the operation room.

[0156] Fig. 9 shows a separation arrangement 90 according to a further embodiment. In contrast to the embodiment of fig. 8, two transfer units 96 in the form of movable belts are provided. Such movable belts can be used to automatically transfer surgical instruments and other items between the two parts of the operation room.

[0157] Fig. 10 shows the separation arrangement according to fig. 9 in another view.

[0158] Fig. 11 shows a separation arrangement 90 according to a further embodiment. In contrast to the embodiment of fig. 8, two tunnel structures 95 are attached to the upper separation wall 92. The tunnel structures 95 cover the two pass-through openings, that are therefore not visible in fig. 11 . The tunnel structures 95 can especially be used in order to provide additional radiation shielding and / or a barrier against passing of contaminants through the pass-through openings 94. In the state shown in fig. 11 , they both extend sidewards and provide a respective opening to the side.

[0159] Fig. 12 shows a separation arrangement 90 according to a further embodiment. In contrast to the embodiment of fig. 11 , a waste container 100 is positioned below the left tunnel structure 95. Furthermore, the left tunnel structure 95 is rotatable so that the opening, which faces to the left side in fig. 12, may also face downwards. A state after such a rotation is shown in fig. 13. In this state, waste may be disposed into the left pass-through opening from behind the separation arrangement 90 and is automatically directed to the waste container 100 by the tunnel structure 95. The tunnel structure 95 thus forms a guiding arrangement.

[0160] Fig. 14 shows a part of the separation arrangement 90 of fig. 11 in a sectional view. The upper wall 92 is not shown in full in fig. 14, and the tunnel structures 95 are also not shown in full. Thus the inside of the tunnel structures 95 is visible, and it can be seen that the tunnel structures 95 are hollow inside.

[0161] Fig. 15 shows a separation arrangement 90 according to a further embodiment. In contrast to the embodiment of fig. 12, there is no waste container 100, at least in the shown state, and there is a connection element 102 at the left side. The connection element 102 is embodied as a flexible material, for example a foil that is retractable into the frame 93. The connection element 102 can be used in order to connect horizontally adjacent separation walls 92, a situation which is shown in fig. 16.

[0162] In fig. 16, three frames 93 each carrying two separation walls 92 one above the other together form a separation arrangement 90. The separation walls 92 of the left frame 93 are embodied as in fig. 13, the separation walls 92 of the middle frame 93 are embodied as in fig. 15, and the separation walls 92 of the right frame 93 do not have any pass- through opening or any other specific element. Between the frames 93, two connection elements 102 being embodied as flexible material, for example a retractable foil are provided. They provide for better separation and shielding against passing of contaminants or ionizing radiation between parts of an operation room. Due to their flexible implementation, they allow flexible and / or adjustable and / or individual positioning of the frames 93.

[0163] Fig. 17 shows the embodiment shown in fig. 16 in another view.

[0164] Fig. 18 shows the apparatus 10 of fig. 1 in a sectional view. As can be seen, the tray 30 is rollable inside the housing 20. For supporting the tray 30 when rolled out, a supporting structure 35 is positioned below the tray 30. The supporting structure is extendable and supports the tray 30 so that it does not bend downwards despite being flexible.

[0165] Fig. 19 shows the apparatus 10 from below. There it can also be seen that the extendable supporting structure 35 supports the flexile tray 30.
