Description

Technical Field

[0002] With the rapid development of science and technology and medical technology, endoscopic minimally invasive or non-invasive medical testing and treatment have become widely used. Existing surgical robots used in surgery utilize an endoscopic system on the patient's surgical platform, allowing the operator to sit or stand in front of the doctor's console and view real-time images of the application scenario on a monitor.

[0003] In practical applications, in addition to the main image displayed on the doctor's console, it is also essential for other doctors or assistants to view supplementary images synchronized with the attending physician. Existing endoscopic systems acquire real-time images of the application scenario through the endoscope, then process these real-time images using an image processor, and finally output the processed images for display. For application scenarios requiring multiple display capabilities, it is necessary to meet both the requirements of reducing latency and timely imaging, as well as the requirement of smooth imaging unaffected by electromagnetic interference. Therefore, this places higher demands on the image processing capabilities of the endoscope. Utility Model Content

[0055] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] In general, surgical robots mainly consist of a surgeon's console, a patient surgical platform, and an image processing platform. The operator can remotely control the surgeon's console, achieving control over the patient surgical platform through a master-slave control relationship. The image processing platform provides the operator with auxiliary surgical environment images. The patient surgical platform includes at least one imaging arm and an instrument arm. The imaging arm is equipped with an endoscope. During surgery, the endoscopic imaging system and surgical instruments are inserted into the patient's location through the incision. The endoscope communicates with a display device, acquiring images of the surgical site (such as surgical instruments, human tissue, blood vessels, etc.) and processing the captured images through an image processor for display on a display device (configured to display images visible to the operator), such as on the surgeon's console or on another suitable display device located locally and / or remotely. The endoscope can be a stereoscopic endoscope; when using a stereoscopic endoscope, the image processor can process the captured images to present a coordinated stereoscopic image of the surgical site to the surgeon. During surgery, the surgical arm moves in accordance with the movement of the main arm mechanism on the surgeon's control console to perform the corresponding surgical procedures.

[0057] This embodiment provides an endoscope system, which includes an endoscope and an image processor. The endoscope is connected to the video input interface 11 of the image processor via a connecting cable to transmit the endoscopic video signal acquired by the endoscope to the image processor. The image processor receives the endoscopic video signal, processes it, and outputs it to a display for viewing by doctors or other personnel. The specific structure of the image processor will be described in detail below.

[0058] Reference Figures 1 to 4 This embodiment provides an image processor, which includes a chassis 100 with a housing cavity 110, a processing motherboard and a power supply module 300 both disposed in the housing cavity 110. The power supply module 300 is connected to the processing motherboard to provide it with power to meet its power requirements and ensure normal operation.

[0059] Combination Figure 1 and Figure 4The chassis 100 includes an upper shell and a lower shell (not shown in the attached drawings). The lower shell includes a base plate 120 and a surrounding plate. The surrounding plate is connected to the base plate 120 and encloses a cavity 110. The upper shell is sealed to the lower shell. This arrangement allows a relatively sealed cavity 110 to be formed inside the chassis 100, which is beneficial for electromagnetic shielding and prevents electromagnetic interference such as static electricity from affecting the motherboard and other components, ensuring their normal operation. Optionally, the chassis 100 can be made of an electromagnetically shielding metal material, such as copper, aluminum, steel, or iron.

[0060] It should be noted that the specific structural design of the chassis 100 is not limited, as long as the structure can form a relatively sealed receiving cavity 110, it is within the protection scope of this utility model.

[0061] Please continue to refer to Figures 1 to 4 The side wall of the chassis 100 is provided with a video input interface 11, two video output interfaces 12 (for ease of description, the two video output interfaces 12 are referred to as the first video output interface and the second video output interface) and a network port 13; the processing motherboard includes a main circuit board 210 and a sub-circuit board 220 arranged adjacent to each other. The main circuit board 210 and the sub-circuit board 220 are communicatively connected and are both covered by a shielding cover 400; the main circuit board 210 is connected to the video input interface 11 and the first video output interface respectively, and is used to receive endoscopic video signals and output a first processing signal to the first video output interface and the sub-circuit board 220; the sub-circuit board 220 is connected to the second video output interface, and is used to receive the first processing signal and output a second processing signal to the second video output interface; the main circuit board 210 and the sub-circuit board 220 are respectively connected to the network port 13 for network communication with the doctor's console.

[0062] With the aforementioned configuration, the main circuit board 210 can receive endoscopic video signals and output a first processing signal to the first video output interface and the secondary circuit board 220 for the first display mode. Simultaneously, the secondary circuit board 220 can receive the first processing signal and output a second processing signal to the second video output interface for the second display mode. Furthermore, the main circuit board 210 and the secondary circuit board 220 are respectively connected to network port 13 for network communication with the doctor's console. Therefore, the division of labor between the main circuit board 210 and the secondary circuit board 220 effectively reduces the processing burden on the main circuit board 210, which helps reduce the display latency of the first display mode, improves the real-time performance and stability of the first display mode imaging, and also enables auxiliary display through the secondary circuit board 220 to meet different usage scenarios.

[0063] In this embodiment of the image processor, on the one hand, the chassis 100 has a receiving cavity 110, within which both the main circuit board 210 and the sub-circuit board 220 are located, providing a certain degree of electromagnetic shielding for both. On the other hand, the main circuit board 210 and the sub-circuit board 220 are arranged adjacently and are both covered by a shielding cover 400, which further reduces electromagnetic interference to both, thus meeting the requirements for successful imaging. Furthermore, the adjacent arrangement of the main circuit board 210 and the sub-circuit board 220, along with the shared shielding cover 400, facilitates the spatial layout of the receiving cavity 110 and the placement of the shielding cover 400.

[0064] In practical applications, the first display mode can be a three-dimensional display mode for the primary physician to view, such as a three-dimensional monitor or a 4K monitor; the second display mode can be a two-dimensional display mode for the nurse or assistant physician to view, such as a two-dimensional touch screen. The specific mode can be adjusted or selected according to actual needs.

[0065] Combination Figure 1 and Figure 4 The shield 400 of this embodiment includes a cover 410 with a side opening. The four edges of the side opening of the cover 410 extend outward to form a flange 420. A first connection hole 421 is provided on the flange 420. A second connection hole is provided on the bottom surface of the chassis 100 at a corresponding position. A fastener is connected between the first connection hole 421 and the second connection hole. For example, the fastener can be a bolt or a screw. In order to ensure the reliability of the connection between the two, the fastener can be set to two, three, four or more sets. For example, four sets of fasteners are arranged in a rectangle.

[0066] In this embodiment, refer to Figures 1 to 3 The video input interface 11 is located on the front panel 130; the two video output interfaces 12 and the network port 13 are located on the rear panel 140; the front panel 130 of the chassis 100 is also equipped with a power switch 15. In actual applications, the interfaces are not limited to the aforementioned arrangement. Any arrangement that can meet the actual connection requirements is within the protection scope of this utility model.

The main circuit board 210 and the secondary circuit board 220 are respectively connected to the network switch 230, and both are connected to the same network port 13 via the network switch 230. This configuration allows for communication between any two of the main circuit board 210, the secondary circuit board 220, and the doctor's console via the network switch 230. Generally, both the main circuit board 210 and the secondary circuit board 220 have only one network port. The network switch 230 effectively reduces the number of network cables and ports required while still enabling communication.

[0068] Specifically, the main circuit board 210 and the secondary circuit board 220 are respectively connected to the first video output interface and the second video output interface via HDMI cables; the main circuit board 210 and the secondary circuit board 220 are respectively connected to the network switch 230 via network cables.

[0069] like Figure 4 or Figure 5 As shown, the network switch 230 is fixedly connected to the bottom surface of the chassis 100 via a mounting bracket 500. For example, the mounting bracket 500 is a cross-shaped bracket, with bends at each of its four ends. Connection holes are provided in the bends for fixing the switch to the bottom surface of the chassis 100 using fasteners.

[0070] Furthermore, the side wall of the chassis 100 is provided with two USB ports 14; a hub 240 is provided on one side of the sub-circuit board 220, and the sub-circuit board 220 is connected to the two USB ports 14 through the hub 240 respectively for data storage and data transmission.

[0071] Specifically, two USB ports 14 are installed on the front panel 130 and the rear panel 140 of the chassis 100, respectively. One USB port 14 is used for data storage, and the other USB port 14 is connected to the two-dimensional touch screen to realize touch operation of the two-dimensional touch screen.

[0072] In this embodiment, the power supply module 300 includes a power socket 310 and a DC power supply 320 connected in series. The power socket 310 is located on the side wall of the chassis 100, and the DC power supply 320 is located in the receiving cavity 110. A splitter 250 is provided on one side of the DC power supply 320 to separate multiple sets of charging interfaces for power supply. The multiple sets of charging interfaces are connected to the main circuit board 210, the sub-circuit board 220, and the network switch 230 respectively via wires to provide power to the three respectively. Exemplarily, the power socket 310 is configured as an integrated product combining a socket, fuse, and filter.

[0073] Reference Figure 4 or Figure 5 The shielding cover 400 and the mounting bracket 500 are both mounted on the same intermediate plate 600, which is fixedly connected to the bottom of the chassis 100. This arrangement facilitates the installation of the processing motherboard and the network switch 230.

[0074] During installation, the main circuit board 210, the secondary circuit board 220 and the network switch 230 can be placed or installed on the intermediate board 600. Then, the intermediate board 600 is placed in the corresponding position of the receiving cavity 110. The shielding cover 400 and the mounting bracket 500 are aligned with the holes on the bottom surface of the intermediate board 600 and the chassis 100, and are fixed in place by fasteners.

[0075] In this embodiment, the shielding cover 400 and the mounting bracket 500 can be made of stainless steel, which can further play the role of electromagnetic shielding, thereby reducing the interference of electromagnetic signals on the main circuit board 210 and the sub-circuit board 220 and ensuring imaging quality.
