Description

[Technical field]

[0001] The present invention relates to a medical system comprising at least two distinct implants and at least two distinct instruments, each of the at least two distinct instruments configured to cooperate with a compatible and associated one of the at least two distinct implants.

[0002] The invention further relates to a method for automatically checking implant and instrument compatibility in a medical system comprising at least two different implants and at least two different instruments, each of the at least two different instruments being configured to cooperate with a compatible and associated one of the at least two different implants. [Background technology]

[0003] Medical systems of the above mentioned type are used in particular in neurosurgery. They comprise a number of different medical clips in the form of aneurysm clips. In particular, the medical clips are formed in different shapes, have different closing forces and are made of different materials, for example titanium or Phynox, depending on the application. Since medical clips are delicate and for a secure implantation it is not possible to apply an arbitrary method using any instrument, for example a pair of forceps or pliers, it is particularly dependent on the clip and different instruments are used in cooperation with the clip. It is important that the instrument and the clip are compatible with each other in order to avoid damage of the clip by the instrument when they work together. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE PRESENT EMBODIMENT It is therefore an object of the present invention to improve medical systems to ensure their availability. [Means for solving the problem]

[0005] This object is achieved by a medical system of the type mentioned at the beginning of the present invention, in that the medical system comprises a microscope defining a microscopic field of view and a compatibility checking device for automatically checking the compatibility of one of at least two different instruments and one of at least two different implants arranged together in the microscopic field of view.

[0006] The proposed development of the known medical system makes it possible in particular to reliably check in a simple manner whether the tool used by the user for implantation and the implant to be implanted are compatible with each other. This check is carried out automatically by the system. For this purpose, the tool and the implant only need to be placed together in the field of view of the microscope. The compatibility check device can recognize the implant and the tool, for example, from their respective shape and / or size or from identification information (for example a code) that characterizes the implant and / or the tool. It should be noted here that in medical systems in which implants are implanted using a microscope, the surgeon often receives the tool already engaged with the implant to be implanted. Since the surgeon only observes the image of the microscope during the operation and his gaze remains directed towards the surgical site, he is not able to check directly with the tool that has been handed over to him whether it is compatible with the implant held there. In the proposed system, in particular when the implant and the tool are placed in the field of view of the microscope, the system can check in a particularly automated manner. It is thus possible, prior to the final placement of the associated implant, to verify in particular whether the instrument / implant combination handed over by the assistant to the surgeon is really intended for collaboration.

[0007] The microscope is preferably in the form of an optical or digital microscope. What type of microscope is ultimately not important for the performance of the compatibility check, which is performed automatically by the compatibility check device of the system. It can therefore be easily retrofitted, for example, to medical systems already in use.

[0008] The microscope is advantageously equipped with an optical microscope image sensor. In particular, this may be configured in the form of a CCD sensor or a CMOS sensor. These types of microscope image sensors are used in particular for digital microscopes, but may also be used for optical microscopes to which a digital camera can be connected. In this way, optical microscopes can be retrofitted. By means of such an optical microscope image sensor, digital images of the microscope field can be generated, stored and further processed. This can also be used to read data such as markings or codes on implants or instruments visible in the microscope field.

[0009] According to a further preferred embodiment, it is provided that the compatibility check device comprises an optical detection device for detecting the optical code, the optical detection device defining a detection field, the microscopic field and the detection field at least partially overlapping. The optical detection device in particular allows an image of the detection field to be generated. In case of an overlap of the detection field and the microscopic field, at least a part of the microscopic field can be captured by the optical detection device. For example, if an optical microscope without a microscope image sensor, i.e. without a digital image capture device, is used, an image of the detection field can be acquired by the optical detection device and, as a result of the proposed configuration, at least a part of the microscopic field can also be acquired. It is thus possible to retrofit a conventional medical system, for example an optical microscope, to be equipped with a compatibility check device.

[0010] To ensure compatibility of the instrument with the implant, it is advantageous if the overlap between the microscope field and the detection field is in the range of about 50% to 100%. In particular, said overlap is in the range of about 80% to 100%. Preferably, said overlap is in the range of about 95% to 100%. The greater the overlap between the microscope field and the detection field, the more reliably all objects in the microscope field can be captured and checked for compatibility. Ideally, said overlap is large enough to ensure that all parts in the microscope field are also visible in the detection field.

[0011] For a quick and simple evaluation of the image of the detection field, it is advantageous if the optical detection device comprises at least one optical image sensor. The optical image sensor may be a CCD sensor or a CMOS sensor. The optical image sensor may, for example, be provided in a camera which is connected to an optical microscope. As mentioned above, the optical microscope can easily be retrofitted. Furthermore, the digital recording can be easily evaluated, e.g. objects or codes present therein can easily be identified.

[0012] If the microscope image sensor defines or forms the optical image sensor, a particularly compact medical system can be provided. In this way, in particular, a complete, i.e. 100% overlap of the detection field and the microscope field is achieved. In other words, in this case, the compatibility check device uses the microscope image sensor to generate a detection field that coincides with the microscope field.

[0013] Preferably, the at least two different implants and the at least two different instruments each have at least one optical code, the optical codes of the at least two different implants being different and the optical codes of the at least two different instruments being different. By coding the implants and instruments in the described manner, the user can distinguish them in a targeted manner. In particular, the optical code can thereby code the size of the instrument or, for example, the shape of the jaw. For example, in the case of an implant such as a medical clip, its size, for example the closing force, the material, etc. can be coded. The optical code also allows a simple and redundant compatibility check to be performed visually, for example if the optical code is a simple color code. Thus, for example, a surgeon's assistant can immediately recognize whether the instrument and the implant are compatible or not by comparing the color codes of the instrument and the implant.

[0014] If an implant and an instrument are compatible with each other and are intended to work together, it is preferable that at least one optical code is identical. Thereby, apart from the automatic compatibility check by the system, the user can also carry out a simple visual check purely optically by observing the instrument and the implant. It is also possible to directly recognize whether the combination of instrument and implant is completely incompatible, for example whether it is permitted by the manufacturer. However, it is not an absolute requirement that instruments and implants compatible with each other have identical codes. Compatibility can also occur, in particular, with different codes, and the compatibility check is carried out by comparison of these codes, which are stored in a corresponding table.

[0015] If the at least one optical code is configured in the form of a bar code, a data matrix code, a QR code, a shape code or a color code, the instruments and the implants can be automatically recognized in a simple manner. Thus, for example, from a digital acquisition of the detection field, the bar code, the data matrix code, the QR code, the shape code or the color code can be easily recognized. The shape code can in particular be defined by the shape of the implant and / or the instrument itself, or at least a part thereof. In this case, an additional code is not absolutely necessary. The code is defined by the implant and the instrument itself. Each implant and / or each instrument may have two or more optical codes. In particular, combinations of the aforementioned code types may be included here. The at least one optical code, in particular the data matrix code and / or other options of the aforementioned optical codes, can also be used as a marker for navigational and / or augmented reality applications during the embedding of the implant, in particular during the application of the medical clip. In particular, non-visible structures such as the implant and the associated instruments can be represented. In particular, the medical clip, the associated clip application instrument and the vascular structure to which the clip is applied can be represented. In particular, by shape recognition it is further possible to evaluate cooperating elements, in particular the surface areas adjacent to each other, of, for example, the medical clip and the clip application tool, with regard to the seating of the clip in a clip receptacle (also designated the jaw of the clip applicator).

[0016] Preferably, the compatibility checking device comprises an image processing device for automatically determining the instruments and / or implants in the microscopic field. The image processing device may in particular be configured for automatically determining the instruments and / or implants in the detection field. The image processing device allows in particular the evaluation of optical codes in the recorded images of the microscopic field and / or the detection field in simple means. This allows for the optimization of processes, e.g. for recording the surgical procedure and for tracking the implants and instruments used.

[0017] The image processing device is preferably configured to read out at least one code of the instruments and / or implants from the images of the detection field and / or the microscope field. An image processing device of this kind can in particular recognize the instruments and implants from their codes and possibly also indicate to the user which instruments and / or implants are involved. Furthermore, the codes can be easily extracted from the images by comparison with stored codes.

[0018] Preferably, the compatibility check device comprises a display device for displaying the result of the compatibility check. This may comprise, for example, a video screen. The display device may also be configured in the form of an acoustic display device for acoustically informing the user whether the implant and the instrument are compatible or not. The display device may be configured in the form of a microscope display or in the form of an external display independent of the microscope. For example, in a hybrid operating room, the display device may comprise data goggles and may also comprise an audio output.

[0019] Advantageously, the microscope comprises a microscope display for displaying an image of the microscope field, which in turn comprises a display. This allows the medical system to be constructed particularly compactly. For example, the display can be constructed in the form of a window or sub-area of ​​the microscope display. This allows the result of the compatibility check to be superimposed, if necessary, on the microscope image displayed on the microscope display. Thus, the surgeon looking at the image of the microscope field (e.g. the surgical site) on the microscope display can receive a direct superimposition of whether the displayed instrument and the implant held thereby are compatible or not.

[0020] According to a further preferred embodiment, it is provided that the at least two implants are configured in the form of medical clips and the at least two instruments are configured in the form of clip application instruments. In particular, the medical clips may be configured in the form of an aneurysm clip. The clip application instrument, also known as an applicator, cooperates with the medical clip to apply the medical clip, for example to treat a bulge on a hollow organ in the human or animal body.

[0021] Preferably, the at least two instruments comprise an instrument end that is engageable with one of the at least two implants, and the at least one optical code is located or configured on or in the area of ​​the instrument end. When the instrument end of the instrument that is located within the microscope field engages with the implant, the code on the implant as well as the code on the instrument can be located in spatial proximity to each other and can thereby be easily captured.

[0022] The object stated in the introduction is further achieved by a method of the type described in the introduction according to the present invention in that the compatibility of the implant and the instrument of the medical system is automatically checked when the implant and the instrument are placed together in the microscope field.

[0023] As explained in detail above, this provides additional assurance when an instrument and an implant are used, since it is not always possible for a user to immediately recognize whether the instrument and the implant are compatible with each other, and thus such a method helps to prevent implanting a particular implant with an instrument that is not intended for that implant.

[0024] Preferably, the implants and the instruments of the medical system have optical codes, and the compatibility is checked by comparison of the optical codes of the implant and the instruments, which are placed together in the microscope field. In this type of method, it is not necessary to have a code table. In particular, the compatibility of new instruments and implants, which have not been stored beforehand in the code table, can also be checked. Compatibility exists in particular when the optical codes of the instruments and the implants are identical.

[0025] To ensure a reliable use of the method, it is advantageous if the comparison result is output. In particular, this is done optically and / or acoustically. For example, a non-compliance can be notified to the surgeon by an audible warning or an appropriate announcement.

[0026] Furthermore, the use of one of the aforementioned systems for carrying out one of the aforementioned methods is proposed. [Brief description of the drawings]

[Diagram 2] FIG. 1 illustrates a schematic diagram of the functionality of an exemplary embodiment of a medical system. [Diagram 3] FIG. 2 is a schematic diagram illustrating the functionality of a further exemplary embodiment of a medical system.

[Figure 6] 1A-1D are schematic diagrams illustrating incompatible instruments and implants. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] An exemplary embodiment of a medical system 10 is illustrated generally in FIG.

[0030] The medical system 10 includes a microscope 12 that defines a microscope field of view 14. The medical system 10 further includes two or more distinct implants 16 and two or more distinct instruments 18. The instruments 18 and the implants 16, when compatible, are configured to cooperate with one another as intended.

[0031] 1, an example of an instrument 18 in the form of a clip applicator 20 is shown which receives and holds an implant 16 in the form of a medical clip 24 at a distal instrument end 22. The medical clip 24 can be opened with the clip applicator 20 and applied to a bulge 26, also called an aneurysm, for example in the form of a hollow organ, particularly a blood vessel 28.

[0032] As shown diagrammatically in Figure 1, the microscope 12 is in the form of a digital microscope. The microscope 12 is provided with a microscope display 30 in the form of a screen 32 on which an image of the microscope field 14 is displayed. A surgeon 34 using instruments 18 monitors the application of the implant 16 on the screen 32.

[0033] 2 shows a schematic representation of an exemplary embodiment of the medical system 10 comprising a compatibility checking device 36 for the purpose of automatically checking the compatibility of an instrument 18 and an implant 16 that are placed together in the microscope field 14.

[0034] The compatibility checking device 36 includes an optical detection device 38, which defines a detection field 40. The detection device 38, which in this exemplary embodiment is provided independent of the microscope 12, is positioned such that the microscope field 14 overlaps the detection field 40 by at least half. Thus, the overlap between the microscope field 14 and the detection field 40 is at least in an area of ​​about 50%.

[0035] The microscope 12, which is represented diagrammatically in Figure 2, is equipped with an optical microscope image sensor 42. This is configured in the form of a CCD sensor or a CMOS sensor.

[0036] The optical detection device 38 comprises an optical image sensor 44, which is configured as a CCD sensor or a CMOS sensor.

[0037] The different implants 16 and the different instruments 18 of the medical system 10 each have an optical code 46, which is configured in the form of a color code 48. In the exemplary embodiment of FIG. 2, the implants 16 are colored. In the instrument 18, a component of the instrument 18 arranged in the region of the instrument end 22 is identified by the color code 48. In the exemplary embodiment of FIG. 2, said component is a locking screw 50 of the instrument 18 configured as a clip applicator 20.

[0038] The optical detection device 38 is configured to detect the optical code 46 by capturing an image of the detection field 40 with the optical image sensor 44. The compatibility check device 36 includes an image processor 52, which allows the instrument 18 and the implant 16 to be captured within the detection field 40 and the area of ​​the microscope field 14 that overlaps with the detection field 40.

[0039] 2, the image processor 52 is configured to read the optical codes 46 of the instruments 18 and implants 16 from the image of the detection field 40. The image processor 52 is thus configured to recognize the color codes 48 of the instruments 18 and implants 16.

[0040] To display the result of the compatibility check, the compatibility check device 36 is provided with a display device 54. In the exemplary embodiment of the medical system 10 shown in Fig. 2, the microscope display device 30 is provided with a display device 54. This is realized in the form of a window superimposed on the image of the microscope field 14 displayed on the screen 32. On the display device 54, whether the color codes 48 of the instruments 18 and the implants 16 match or not is indicated in text form (in a manner not shown) or, for example, by a signal display. This is the case in the exemplary embodiment shown in Fig. 2.

[0041] The image of the microscope field 14 created by the microscope image sensor 42 is processed by the processor 56 and displayed on the microscope display 30.

[0042] A further exemplary embodiment of the medical system 10 is shown diagrammatically in Fig. 3. In this exemplary embodiment, the optical detection device 38 is integrated into the microscope 12. The microscope image sensor 42 forms an optical image sensor 44.

[0043] The compatibility check device 36 comprises, inter alia, the microscope 12 and a display device 54 included in the microscope display device 30. The image of the microscope field 14 produced by the microscope image sensor 42 is processed in an image processing device 52 integrated in the computing device 56 and displayed on the microscope display device 32. The results of the compatibility check are displayed on the screen 32 in the form of explanatory text and / or in the form of signal displays, as described above in particular in connection with the exemplary embodiment of FIG.

[0044] In the schematic exemplary embodiment shown in FIG. 3, the optical code 46 is provided on the instrument 18 and the implant 16 , specifically in the form of a Data Matrix code 58 .

[0045] The image processor 52 is configured to extract the optical codes 46 of the instruments 18 and implants 16 from the images of the microscope field 14 acquired by the microscope image sensor 42 and to compare them with each other.

[0046] Both the exemplary embodiment of the medical system of Fig. 2 and the exemplary embodiment of the medical system of Fig. 3 are optionally configured to extract a shape code from the image of the microscope field 14 and / or the image of the detection field 40. The shape code 60 is defined by the implant 16 itself and by the instrument 18 itself. In particular, both exemplary embodiments are also able to recognize different codes 46 on the implant 16 and on the instrument 18. This also allows a more reliable check of the implant 16 and the instrument 18, since during the check of the two optical codes 46 on both the implant 16 and the instrument 18, a redundant compatibility information item is obtained.

[0047] In the exemplary embodiment of FIG. 3, the optical code 46 is disposed distal to a locking screw 50 on the device 18 and thereby in the region of the instrument end 22 .

[0048] 4 shows a schematic diagram of the overlap between the microscope field 14 and the detection field 40. To perform a compatibility check, the implant 16 and the instrument 18 must be placed in the microscope field 14 and the detection field 40 at the same time, and the optical codes 46 on both the implant 16 and the instrument 18 must be captured at the same time. This allows the compatibility check device 36 to compare both captured optical codes 46, and automatically confirm the compatibility of the implant 16 and the instrument 18 if the two optical codes 46 are identical, or to output a warning if the two optical codes 46 are different.

[0049] 5 and 6 show a schematic representation of these two options, ie, compatibility and incompatibility of the implant 16 and device 18. FIG.

[0050] In Fig. 5, both the instrument 18 and the implant 16 are provided with two optical codes 46, one as a color code 48 and the other as a data matrix code 58. Furthermore, the shape of the instrument 18 and the shape of the implant 16 can be optionally captured and checked for compatibility.

[0051] In the example of Fig. 5, the two optical codes 46 match. In the example of Fig. 6, both the color code 48 and the Data Matrix code 58 are different. Thus, in the situation according to Fig. 5, the compatibility of the device 18 with the implant 16 can be confirmed, whereas in the example of Fig. 6, the compatibility is denied. For example, a warning can be output.

[0052] In an alternative exemplary embodiment not shown, a further optical code in the form of a bar code or QR code may alternatively or additionally be provided.

[0053] The optical code 46 may distinguish between implant sizes, for example three different size families, specifically "standard", "mini" and "long". These three size families correspond to three compatible associated instruments 18. The three sizes may be coded by an appropriate color code, for example blue for "standard", red for "mini" and green for "long".

[0054] The color code can be used in particular to distinguish between implants that remain in the body, such as permanent clips of an aneurysm clip system, or temporary implants, such as temporary clips of such an aneurysm clip system. In particular, a color code for the information "permanent" or "temporary" can be captured in addition to a color code for the size.

[0055] By means of the Data Matrix code, different items of information regarding the instrument 18 and the implant 16, such as the date of manufacture, the closing force of the clip, the material of the clip, etc., can be stored by being coded directly on the instrument 18 and / or on the implant 16. The information coded in the Data Matrix code can in particular also be used for tracking and recording surgical interventions. Thus, in the described exemplary embodiment of the medical system 10, not only can the compatibility of the instrument 18 with the implant 16 be checked, but the established information can also be used for process optimization. For example, it is possible to automatically trigger a reordering process when a particular implant 16 is implanted. Furthermore, the implanted implants can also be directly assigned to the patient identification card. Furthermore, it can be established many times which type of implant 16 was permanently implanted and which temporary implant 16 was used.

[0056] Implants 16 and instruments 18 can also be tracked by the described exemplary embodiment of the medical system 10, particularly during surgery and preparation. This is a service to the user and provides a data collection system to the manufacturer, allowing registration data to be captured and used in clinical studies.

[0057] In the exemplary embodiment of Fig. 2, the detection device 38 is arranged separately from the microscope 12. It can be realised in the form of any desired digital camera, for example in an operating theatre a navigation camera or data goggles with an integrated camera can be used for this purpose.

[0058] An additional screen may also be provided to integrate the display 54 into the microscope display 30. The results of the compatibility check may be displayed on a pair of data goggles worn by the surgeon, or may be acoustically provided by an audio output.

[0059] The exemplary embodiment of the medical system 10 as described can facilitate automatically checking whether the instruments 18 and the implants 16 that are to be used together are compatible with each other. This information is very important, especially since it can avoid damage to the implants 16 due to the use of an incompatible instrument 18. [Explanation of symbols]
