Technical Field
[0001] The present invention belongs to the technical field of medical devices and relates to an intelligent surgical exoscopic system. Background Art
[0002] In recent years, with the rapid development of medical imaging technology, surgical procedures have gradually moved towards minimally invasive and precision surgery. As an important auxiliary tool, exoscopic systems have played a vital role in minimally invasive surgery, open surgery, and remote collaboration. Exoscopic systems use cameras to transmit real-time images of the surgical area to a monitor for the doctor to observe and operate. This allows doctors to perform precise surgical procedures with minimal exposure to the patient's internal tissues, thereby reducing surgical trauma, shortening postoperative recovery time, and improving surgical outcomes.
[0003] While a wide variety of surgical exoscopic systems are currently available on the market, some significant challenges remain. For example, exoscopic systems lack intelligence and convenience, often lacking multimodal imaging and multifunctional sensing capabilities, and their lenses cannot automatically adjust their focus. During surgery, the obstruction of the shadowless lamp significantly interferes with surgical imaging, impacting surgical quality. Furthermore, information transmission methods are complex and susceptible to interference during transmission, leading to display delays or reduced image quality.
[0004] Therefore, there is an urgent need for a new surgical exoscopic system to address the shortcomings of existing technologies, provide more intelligent services, more efficient signal transmission, and more comfortable user experience to meet the needs of modern surgical operations.

It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0042] The present invention provides an intelligent surgical exoscopic system, such as Figure 1 、2 As shown in Figure 3, it includes: a workbench, a pneumatic robotic arm, an intelligent multi-optical imaging system 11 located at the end of the pneumatic robotic arm, and a 3D display device. The workbench includes a housing 3, a display rotating bracket 6.1, a four-star base 2, and universal casters 1. The pneumatic robotic arm includes a pneumatic robotic arm 7, a pneumatic robotic arm 8, a pneumatic camera arm 10, and spherical joints. The spherical joints include a main arm spherical joint 9.1; a lower arm spherical joint 9.2; and a sub-arm spherical joint 9.3.
[0043] Specifically, the pneumatic manipulator arm 7 in this embodiment is fixed to the housing 3 and connected to the pneumatic manipulator arm 8 via a main arm spherical joint 9.1. The two pneumatic manipulator arms 8 and the pneumatic camera arm 10 are interconnected via a lower arm spherical joint 9.2. The pneumatic camera arm 10 is connected to the camera system via a sub-arm spherical joint 9.3. The spherical joints in this embodiment can rotate about three mutually perpendicular axes, providing three degrees of freedom. Therefore, the pneumatic manipulator arm in this embodiment is flexible and has a wide range of motion, with a maximum arm span of 1600 mm.
[0044] Specifically, the intelligent multi-light path imaging system 11 includes five integrated zoom imaging light paths 17.1, an intelligent focus controller 12, and a ring integrated chip 18. Figure 4 As shown, the five zoom imaging optical paths 17.1 in this embodiment are distributed in a circular array around the central axis of the intelligent multi-optical path imaging system 11, with a resolution of 3840×2160, an optical zoom ratio of 13 times, and automatic focus and viewing angle adjustment functions.
[0045] Specifically, the ring-shaped integrated chip 18 is mounted on the periphery of the five zoom imaging optical paths 17.1. It has a total height of 6mm, an inner ring radius of 17mm, and an outer ring radius of 22mm. It is made of four MEMS microsensors: a thermal imaging sensor, a gas sensor, a Raman spectrometer sensor, and a temperature and humidity sensor, stacked vertically and compactly. Through-silicon via (TSV) technology is used to achieve inter-layer interconnection. The periphery is connected to a micro-ultrasound probe and a micro-fiber probe via a flexible printed circuit. TSV technology enables high-density, low-latency electrical connections between the layers of the ring-shaped integrated chip 18, while significantly reducing horizontal space usage.
[0046] Specifically, the stacking diagram of the ring integrated chip 18 is as follows: Figure 6 As shown, the specific configuration is as follows: a high-performance system on chip (SoC) 22 is set on the top layer, which integrates a signal processing unit, an analog-to-digital converter and a communication module to realize real-time data processing and transmission; a thermal imaging sensor layer 23, a gas sensor layer 24, a Raman spectrum sensor layer 25 and a temperature and humidity sensor layer 26 are sequentially set on the lower layer; the arrow represents the direction of data transmission, and the data is transmitted to the surgical exoscope body.
[0047] The 3D display device includes a polarized 3D main screen 13, a polarized 3D secondary screen 14, and a head-mounted display device (HMD) 15; the polarized 3D display main screen 13 and the secondary screen 14 are connected to the box 3 through the display rotating bracket 6.1, and can be rotated on a fixed axis to facilitate adjustment according to the operator's orientation.
[0048] The head mounted display device 15 includes VR glasses and AR glasses. In the embodiment, the size of the polarized 3D display main screen 13 is 24 inches, and the size of the polarized 3D display sub-screen 14 is 12 inches.
[0049] The auxiliary control device includes a pressure-sensitive foot pedal.
[0050] Specifically, the pressure-sensitive foot pedal is composed of a base 19.1, a pedal 20.1, and a fixing block 21.1, and there are two left and right pedals. Figure 5 The pressure sensor and tilt sensor are used to control the position and height of the intelligent multi-path imaging system. Specifically, the following methods are used: stepping on the front of pedal 20.1 moves forward; stepping on the rear of pedal 20.1 moves backward; stepping on the left side of pedal 20.1 moves left; stepping on the right side of pedal 20.1 moves right; stepping on the center adjusts the height; stepping on both feet zooms in or out; and controlling the movement speed by tilting the feet. Stepping on fixing block 21.1 fixes the position of intelligent multi-path imaging system 11; lifting fixing block 21.1 releases the fixation. The operation screen 5 allows the operator to customize different function combinations.
[0051] The front end of the box body 3 is provided with a robotic arm control system, an image processing host, and a light source control system, and the rear end of the box body 3 is provided with a drawer 14 for storing medical equipment, etc. The outside of the box body 3 is provided with an operation screen 5 and heat dissipation holes 4.
[0052] The robotic arm control system can provide motion control, posture adjustment, automatic positioning, balance control, safety functions, braking functions, sensor feedback, and integration functions.
[0053] Specifically, the image processing host is mainly used to process the image information obtained by the intelligent multi-optical path imaging system 11 and output it in the output mode required by the user. The output mode includes a naked eye 3D mode and an HMD mode. The naked eye 3D mode is suitable for the polarized 3D main screen 13 and the auxiliary screen 14. The HMD mode is suitable for the head-mounted display device 15, such as Figure 4 As shown, in this embodiment, the image processing host performs simultaneous output of naked eye 3D mode and HMD mode.
[0054] The image processing host can provide intraoperative navigation. Specifically, this involves constructing a three-dimensional model of the patient's anatomical structure using pre-acquired medical imaging data (such as CT and MRI), registering the exoscope's real-time position and posture with the three-dimensional model, and achieving real-time positioning of the exoscope within the patient's body. The exoscope's current position and field of view are then displayed on the three-dimensional model, providing intraoperative navigation for the doctor.
[0055] The image processing host can provide a path planning function. Specifically, based on the surgical objectives and anatomical structures, the intelligent multi-path imaging system 11 automatically generates an optimal path to the target site. Combined with the navigation system, it guides the system along the planned path, avoiding critical blood vessels and nerve tissue. Path optimization can be performed based on factors such as surgical safety and operation time.
[0056] Specifically, the image processing host can also comprehensively utilize a deep learning-based brightness compensation model, multi-scale analysis, and edge-preserving technology to solve the problem of decreased brightness in the surgical field caused by the obstruction of the shadowless lamp during surgery. The specific implementation method is as follows: training a convolutional neural network (CNN) specifically for surgical field brightness compensation, using a large amount of occluded and non-occluded surgical field image data for learning, so that it can automatically estimate and compensate for local brightness; applying the CNN model to surgical field images of multiple scales, and using multi-scale fusion technology to obtain clearer and more natural enhancement results; at the same time, we introduced an edge-aware loss function in the CNN model, and applied an edge-preserving filter in the post-processing stage to ensure that the enhanced image can retain key structural details and avoid image distortion or artifacts.
[0057] The light source control system can provide light source brightness adjustment, spectrum adjustment, light source stability control, and uniform lighting detection functions.
[0058] Specifically, the spectral adjustment function of the light source control system is used for multimodal imaging; such multimodal imaging includes white light imaging, ICG fluorescence imaging, and narrowband imaging. The intelligent multi-optical path imaging system 11 in this embodiment integrates five zoom imaging optical paths 17.1. When the use of the 3D display device is reduced, the zoom imaging optical path 17.1 can be reserved for multimodal imaging.
[0059] Specifically, the light source control system is connected to the zoom imaging optical path 17.1 via an optical fiber. In this embodiment, each of the five imaging optical paths 17.1 is provided with an optical fiber connected to the light source control system for light source transmission to meet the needs of multimodal imaging.
[0060] The operation screen 5 is used to start and shut down the exterior mirror system, manually adjust the pneumatic robotic arm when necessary, set the output mode of the image processing host, and control the imaging mode.
[0061] Specifically, the five zoom imaging optical paths 17.1 integrated in the intelligent multi-optical path imaging system 11 are used to simultaneously perform multi-viewpoint 3D imaging and multi-modal imaging. Figure 4 This diagram illustrates a multi-viewpoint 3D imaging method for an intelligent multi-optical imaging system 11 in an embodiment. Five 3D display devices capture 3D scene information from different perspectives. Any two zoom imaging optical paths 15.1 within the intelligent multi-optical imaging system 11 are selected. These two optical paths can respectively simulate the imaging systems of the left and right eyes of the human body, simultaneously capturing two sets of images of the same surgical field. These two sets of images are then synthesized in three dimensions by the image processing host and output in glasses-free 3D mode to a polarized 3D main screen 13 and a secondary screen 14, or in HMD mode to a head-mounted display device 15. The choice of perspective depends on the position of the surgeon. Preferably, adjacent zoom imaging optical paths 17.1 are output to a single 3D display device, as shown. In this case, four surgeons can perform surgery using the head-mounted display device 15 while one surgeon performs surgery using the polarized 3D main screen 13. When performing multimodal imaging, the use of 2 to 4 head-mounted display devices 15 can be reduced accordingly, and the 1 to 3 vacant zoom imaging optical paths 17 . 1 can be used for imaging in other modalities respectively.
[0062] Specifically, the 3D scene information obtained after processing by the image processing host and the information transmission method between the 3D display device, the pressure-sensitive foot pedal and the robotic arm control system is 5G wireless transmission. Because the transmitted information involves the privacy data of multiple parties, a specific medical channel will be selected for encrypted transmission during transmission, while ensuring high frame rate and high-quality transmission.
[0063] Specifically, the intelligent focusing controller 12 adopts a rotary button design, and the specific implementation method is: the button can be pressed and rotated, pressing is used to switch between automatic focus and manual focus mode, and rotating is used for manual focus, accompanied by sound feedback to inform the operator of the focus status.
[0064] Specifically, the thermal imaging sensor is used to help the surgeon perform tissue perfusion assessment, tumor or inflammation detection, etc. Its specific implementation method is: it works by detecting infrared radiation emitted from the surface of an object, converting these radiations into electrical signals and processing them into temperature distribution images. The results are superimposed in real time on the polarized 3D main screen 13 or presented separately on the polarized 3D sub-screen 14.
[0065] Specifically, the gas sensor is an electrochemical sensor used to detect changes in gas composition in the surgical area, which may help to detect complications early and can perform tissue metabolism monitoring, hypoxia detection, infection or necrosis indication.
[0066] Specifically, the Raman spectroscopy sensor can provide the operator with real-time tissue composition analysis capabilities in a non-invasive manner. Its specific implementation method is as follows: a miniature fiber optic probe is connected to an optical fiber to emit near-infrared light to the tissue and collect scattered light from the tissue at the same time. The small high-sensitivity spectrometer on the sensor analyzes the scattered light collected from the tissue, and the sensor data processing unit analyzes the spectral data in real time. The results are superimposed in real time on the polarization 3D main screen 13 or presented separately on the polarization 3D secondary screen 14.
[0067] Specifically, the temperature and humidity sensor is used to monitor the temperature and humidity of the operating environment.
[0068] Specifically, the micro-ultrasound probe is a miniaturized ultrasonic imaging device that can provide the surgeon with real-time deep tissue structure information, assist in surgical navigation, and improve its accuracy.
