[0002] The use of medical equipment is crucial to patient safety. During some surgeries, doctors can operate surgical instruments / medical devices manually and control the equipment via foot switches to perform related operations, such as controlling the working status of energy components or the movement of robotic arms. Since foot switches are usually placed in easily accessible locations for doctors, such as under the bed or on the bottom of the medical equipment, doctors typically need to stop what they are doing, look down to check the position of their feet relative to the foot switch, and press it accurately. This inconveniences doctors and affects surgical efficiency. This is especially true for endoscopic systems and surgical microscopes, where the doctor's observation posture and field of vision are relatively limited. The process of having to leave their observation position and look down to locate the foot switch can easily distract them.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The following is combined Figures 1-3 This invention describes a foot switch position display system and a medical system.

[0030] like Figure 1 As shown, the present invention provides a foot position display system, including: a floor mat 100 and a data processing unit 300; The floor mat 100 is equipped with a force sensor array that can collect the position of the operator's feet; When in use, a foot switch 200 is placed on the floor mat 100; The force sensor array is connected to the data processing unit 300. The data processing unit 300 processes the force sensor data to obtain the relative positional relationship between the foot and the foot switch 200, and displays it through the display module 400.

[0031] Specifically, foot switch 200 is a foot switch for medical devices, such as exoscopy systems, surgical microscope systems, semiconductor laser therapy systems, robotic drill-based automated bone-grinding systems, robotic endoscope systems, endoscopic systems, spinal robot systems, etc. Medical devices may include one or more foot switches, and each foot switch may include one or more foot control units, which can respectively provide control signals, such as controlling the movement and stop of a robotic arm, controlling the execution of a photograph, or controlling the output of laser energy. In use, the foot switch 200 of the medical device is placed on the floor mat 100.

[0032] Reference Figure 2The floor mat 100 is also equipped with a force sensor array. The distribution of the force sensors on the floor mat 100 can be regular or irregular. For example, force sensors can be densely arranged in areas where feet are more likely to step on the mat, and sparsely arranged at the edges of the floor mat 100. When detecting the foot position, the "stepping area" can be determined as the foot position based on the positions of multiple force sensors on the floor mat 100, thereby determining the operator's foot position. In addition, the position of the foot switch 200 on the floor mat 100 can also be obtained. For example, the position of the foot switch 200 is known, or the position of the foot switch 200 is detected by a hardware module (such as the force sensor array on the floor mat 100, or a navigation tracking device). The data processing unit 300 can determine the relative positional relationship between the operator's foot and the foot control module based on this information and display it through the display module 400. The operator can directly observe the display module 400 to understand the relative positional relationship between the foot and the foot switch 200 without interrupting the operation or shifting their gaze significantly.

[0033] The data processing unit 300 is a hardware module based on a general computer architecture. It can share the host of the medical device or be an independent module.

[0034] The display module 400 can be independently configured or shared with the display module 400 of the medical device. Examples of display modules 400 include screens on operating carts, external viewing screens, projectors, wearable devices (such as AR glasses or VR glasses), and eyepieces of surgical microscope systems. For scenarios where the image is displayed on the surgical microscope eyepiece, the specific implementation can be as follows: A projection component projects an image containing the aforementioned relative positional relationships. The projected light is reflected by the reflective surface of a semi-transparent mirror. Light from the surgical area passes through the semi-transparent mirror and merges with the reflected light. The operator can then see the surgical area and the relative positional relationship between the virtual projection of their feet and the foot switch 200 in the eyepiece.

[0035] The foot position display system provided in this embodiment can sense and intuitively display the relative position relationship between the foot and the foot switch, so that the operator can understand the relative position relationship between the foot and the foot switch by directly observing the display module without interrupting the operation or shifting the observation line. This improves the convenience and safety of operation.

[0036] Furthermore, in some embodiments, the foot switch 200 may simultaneously include foot switches for multiple types of medical devices, such as foot switches for surgical microscope systems, foot switches for laser therapy devices, foot switches for endoscope systems, and foot switches for electrocoagulation hemostasis devices.

[0037] Furthermore, in one example, the data processing unit 300 displays the relative positional relationship between the foot and the foot pedal switches of each medical device through a summary display module 400. In another example, the data processing unit 300 performs data processing and displays the relative positional relationship between the foot and its respective foot pedal switch through the display modules 400 of each medical device.

[0038] Based on the foregoing embodiments, in some embodiments, a preset area for placing the foot switch 200 is provided on the floor mat 100.

[0039] Specifically, the foot switch 200 is set in a preset area of ​​the floor mat 100. At this point, the position of the foot switch 200 on the floor mat 100 is known, eliminating the need for additional hardware to detect its position. Furthermore, for example, a marker can be added to the floor mat 100 to indicate the preset area for placing the foot switch 200. Before use, the foot switch 200 is placed in this marked area. Alternatively, the floor mat 100 can be provided with a slot for placing the foot switch 200. Placing the foot switch 200 into the slot before use effectively prevents it from shifting during operation.

[0040] Furthermore, there can be multiple foot switches 200, each foot switch 200 having its own preset area on the floor mat 100. The data processing unit 300 distinguishes different foot switches 200 according to different preset areas. (Refer to...) Figure 3 The mat has three preset areas: A, B, and C. Area A on the mat 100 can be pre-positioned with the foot switch for controlling imaging, area B with the foot switch for controlling irrigation / rinsing, and area C with the foot switch for adjusting lighting brightness. Before use, the corresponding foot switches are placed in areas A and B. During use, a force sensor array detects the operator's foot position, directly determining the relative position of the foot to the foot switches in areas A, B, and C. In another example, the foot switches for each preset area can be temporarily calibrated before use. For example, before use, the doctor can place three foot switches in areas A, B, and C according to their needs and placement habits (or only one or two). The doctor then confirms the function of the foot switches in each preset area, for example, by selecting / inputting / confirming the function of each foot switch in the software interface, thus completing the calibration process.

[0041] Based on the foregoing embodiments, in some embodiments, the foot switch 200 is movably disposed on the floor mat 100, and the floor mat 100 acquires the position of the foot switch 200 through a force sensor array.

[0042] Specifically, several force-bearing areas (connected regions) are determined based on the positions of multiple force sensors on the floor mat 100, and the shape of the force-bearing areas determines whether a certain force-bearing area is a "foot" or a "foot switch 200".

[0043] Furthermore, in scenarios with multiple foot switches 200, it may not be possible to distinguish different foot switches by their "shape" alone. To address this, different weights can be assigned to different foot switches 200 (e.g., by adding counterweights), and the differences in the "force" applied to each foot switch 200 area can be used to further distinguish the different foot switches 200.

[0044] Of course, the function corresponding to the different "foot switches" on the mat can also be determined through a "calibration" process. For example, several force-bearing areas can be detected by an array of force sensors on the mat and presented in a diagram. One force-bearing area is shaped like a "foot," corresponding to the doctor's foot, while other force-bearing areas are shaped like "foot switches." After visually observing, the doctor can confirm / input / select the function corresponding to each "foot switch" area, facilitating the doctor's correct operation of the foot switches in subsequent stages. In this example, it is not necessary to set different weights for each foot switch.

[0045] Based on the foregoing embodiments, in some embodiments, the display module 400 shares the same display module as the medical device.

[0046] Specifically, using the display module of a medical device to display foot position information can simplify the system structure and reduce product costs. Understandably, to display the relative position information of the foot and foot pedal on the display module of the medical device, a data connection needs to be established between the data processing unit 300 and the display module of the medical device to transmit and display the relative position information of the foot and foot pedal. One implementation method is to wirelessly connect the data processing unit 300 of the foot pedal position display system to a USB wireless receiver, which is plugged into the medical device host. The medical device host is configured to support "receiving and displaying the relative position information of the foot and foot pedal through the display module." The specific configuration process can refer to existing computer technology. Another implementation method is to connect the data processing unit 300 and the medical device via a physical data cable to transmit the relative position information of the foot and foot pedal to be displayed.

[0047] Based on the foregoing embodiments, in some embodiments, the system includes a separate display module 400. Specifically, in this embodiment, the display module 400 is part of the foot pedal position information display system, and the relative position information between the foot and the foot pedal switch 200 is directly displayed using a separate display module 400. This embodiment does not require borrowing the display module of the medical device, does not require configuration of the host of the medical device, and does not require requesting relevant permissions.

[0048] Furthermore, the independent display module 400 communicates wirelessly with the data processing unit 300, allowing for flexible placement of the display module 400 during use, thus improving ease of use.

[0049] Based on the foregoing embodiments, in some embodiments, the data processing unit 300 is integrated on the floor mat 100. In other embodiments, the data processing unit 300 is integrated on the display module 400, and the data collected by the force sensor array on the floor mat 100 is transmitted to the data processing unit 300 via wired / wireless means, reducing the manufacturing difficulty of the floor mat and extending its service life.

[0050] The following describes a medical system provided by this utility model. The medical system described below can be referred to in correspondence with the foot pedal position display system described above.

[0053] Medical devices may include one or more foot switches, and each foot switch may include one or more foot control units that can provide control signals, such as controlling the movement and stopping of a robotic arm, controlling the execution of a photograph, or controlling the output of laser energy.

[0054] Display modules can be independently configured or shared with other medical devices. Examples of display modules include screens on operating carts, external endoscope screens, projectors, wearable devices (such as AR glasses and VR glasses), and eyepieces of surgical microscope systems.

[0055] The foot position display system includes a data processing unit and a floor mat. The data processing unit can be a hardware device based on a general-purpose computer architecture, sharing the main unit of the medical device; alternatively, it can exist independently. The floor mat is equipped with an array of force sensors. The distribution of these force sensors can be regular or irregular; for example, force sensors can be densely arranged in areas where feet are more likely to step on the foot, and sparsely arranged at the edges of the mat. When detecting foot position, the "stepping area" can be determined based on the positions of multiple force sensors on the floor mat, thus identifying the operator's foot position.

[0056] The data processing unit collects the relative positional relationship between the foot and the foot switch through the floor mat, and generates a schematic diagram based on this relationship, which is displayed through the display module. The operator can directly observe the display module to understand the relative positional relationship between the foot and the foot switch without interrupting the operation or shifting their gaze significantly.

[0057] The medical system provided in this embodiment can sense and intuitively display the relative position of the foot and the foot switch, so that the operator can understand the relative position of the foot and the foot switch by directly observing the display module without interrupting the operation or shifting the observation line. This improves the convenience and safety of operation.

[0058] Further embodiments of the medical system can be found by analogy with the foot pedal position display system described above, and will not be repeated here.

[0059] The following describes a surgical microscope system provided by this utility model. The surgical microscope system described below can be referred to in correspondence with the foot switch position display system and medical system described above.

[0060] The present invention provides a surgical microscope system, comprising: a position adjustment module, an image acquisition module, a display module, a foot switch, a floor mat, and a data processing unit; The position adjustment module can adjust the position and viewing angle of the surgical image acquisition module. In one example, the position adjustment module includes a movable base, a column, and a suspension arm. The column is mounted on the movable base, and the upper end of the column is connected to the suspension arm. The other end of the suspension arm is connected to the image acquisition module. Overall, the position adjustment module can be adjusted in a wide range using the base, and the position and viewing angle of the image acquisition module can be further adjusted using the suspension arm. In another example, the position adjustment module includes a movable base, a trolley, and a robotic arm. The trolley is mounted on a movable chassis, and the base of the robotic arm is mounted on the trolley. The other end of the robotic arm is connected to the image acquisition module. Overall, the position adjustment module can be adjusted in a wide range using the base, and the position and viewing angle of the image acquisition module can be further adjusted using the robotic arm. The aforementioned data processing unit can also be installed in the trolley.

[0061] The image acquisition module may include an illumination unit, or an illumination unit may be set in another location on the surgical microscope system, which can supplement the light in the surgical area for clear imaging.

[0062] The surgical microscope system may include one or more foot switches, and each foot switch may include one or more foot control units. Each foot control unit may perform different control functions, such as controlling the movement and stopping of the position adjustment module, controlling the execution of a single photograph, adjusting the magnification of the image acquisition module, adjusting the working distance of the image acquisition module, etc.

[0063] The mat can collect data on the relative position between the operator's (i.e., the person operating the surgical microscope system, such as a doctor) feet and the foot switch, and transmit this data to the data processing unit. Specifically, the mat is equipped with an array of force sensors. The distribution of these force sensors can be regular or irregular; for example, force sensors can be densely arranged in areas where feet are more likely to step on the mat, and sparsely arranged at the edges. When detecting foot position, the "stepping area" can be determined as the foot position based on the positions of the multiple force sensors on the mat, thereby determining the operator's foot placement.

[0064] The data processing unit can be a hardware device based on a general-purpose computer architecture, sharing the main unit of the medical device. Alternatively, the data processing unit can exist independently. The data processing unit collects the relative positional relationship between the foot and the foot switch via the floor mat, generates a schematic diagram based on this relationship, and displays it through the aforementioned display module. The operator can directly observe the display module to understand the relative positional relationship between the foot and the foot switch without interrupting their operation or significantly shifting their gaze.

[0065] In some examples, the surgical microscope system includes a separate display module, such as a screen mounted on a trolley, to which the data processing unit sends an image illustrating the relative positional relationship between the foot and the foot switch for display. In another example, the display module is a projection component on the image acquisition module. This component overlays an image illustrating the relative positional relationship between the foot and the foot switch onto the eyepiece optical path of the image acquisition module. Specifically, the projection component projects an image containing the aforementioned relative positional relationship; the projected light is reflected by a semi-transparent mirror; the light from the surgical area passes through the semi-transparent mirror and merges with the reflected light; the operator's glasses receive this merged light through the eyepiece, allowing them to observe the superimposed image of the surgical area.

[0066] The surgical microscope system provided in this embodiment can sense and intuitively display the relative position of the foot and the foot switch, so that the operator can understand the relative position of the foot and the foot switch directly through the display module without interrupting the operation or shifting the observation line over a large area, thus improving the convenience and safety of operation.

[0067] For further embodiments of the surgical microscope system provided by this utility model, please refer to the medical equipment and foot switch position display system described above, which will not be repeated here.

[0068] The following describes an endoscope system provided by this utility model. The endoscope system described below can be referred to in correspondence with the foot switch position display system and medical system described above.

[0069] The present invention provides an endoscope system comprising: an endoscope lens, a light source module, a display module, a foot switch, a floor mat, and a data processing unit; Specifically, endoscopic systems are used for imaging and observation of confined spaces, such as the abdomen, esophagus, deep brain, and lumbar spine. Endoscopic lenses can be rigid or flexible. Rigid endoscopes have a rigid tube containing illumination channels, image acquisition channels, and may also include flushing channels and working channels (e.g., for inserting cutting or electrocautery tools). Flexible endoscopes have at least partially flexible tubes to facilitate passage through confined spaces within the body, and a display module shows the images acquired by the endoscopic lens.

[0070] An endoscope system may include one or more foot switches, and each foot switch may include one or more foot control units.

[0071] The mat also features an array of force sensors. The distribution of these sensors can be regular or irregular; for example, force sensors can be densely arranged in areas where feet are more likely to step on the mat, and sparsely arranged at the edges. When detecting foot position, the "stepping area" can be determined based on the positions of the multiple force sensors on the mat, thus identifying the operator's foot placement.

[0072] The data processing unit can be a hardware device based on a general-purpose computer architecture, sharing the main unit of the endoscope system. Alternatively, the data processing unit can be an additional component. The data processing unit collects the relative positional relationship between the foot and the foot switch via a floor mat, generates a schematic diagram based on this relationship, and displays it through the aforementioned display module. The operator can directly observe the display module to understand the relative positional relationship between the foot and the foot switch without interrupting their operation or significantly shifting their gaze.

[0073] In some examples, the endoscope system includes a display module that displays both the endoscopic image and the positional relationship between the foot and the foot switch; these two images can be displayed overlaid. Preferably, the endoscopic image can be displayed in full screen, while a schematic diagram showing the positional relationship between the foot and the foot switch is displayed in a localized area of ​​the display module.

[0074] In other examples, the endoscope system includes two or more display modules that can display endoscope images and the positional relationship between the foot and the foot switch on different screens.

[0075] The endoscope system provided in this embodiment can sense and intuitively display the relative position of the foot and the foot switch, so that the operator can understand the relative position of the foot and the foot switch directly through the display module without interrupting the operation or shifting the observation line. This improves the convenience and safety of operation.
