Compared with traditional surgical methods, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. The endoscope used in minimally invasive surgery allows doctors to capture images of the patient's internal tissues by inserting the instrument through a natural body orifice or surgically created opening and guiding it to the target location in the patient's body.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0062] In this embodiment, refer to Figure 1 The endoscope camera system is mainly composed of several modules such as an endoscope 10, an image processing module 30 and a display. Among them, the image acquisition module 20 is arranged inside the endoscope 10. The endoscope 10 includes a pipe with a light source, which enters the human body through the natural cavity of the human body or a small incision in minimally invasive surgery to help doctors diagnose diseases or assist in surgery.

[0063] Specifically, the endoscope 10 includes a shaft and a handle coupled to the proximal end of the shaft, and when in use, the handle is configured to be located outside the patient. The shaft has a distal end or front end, which is configured to be inserted into a surgical site in the patient.

[0064] It should be noted that the patient's "surgical site" may be completely within the patient's body and may include a site in the patient's body near a planned, ongoing, or already performed surgical procedure. In other examples, the surgical site may be at least partially outside the patient. In some embodiments, the shaft may be rigid. Alternatively, the shaft may also be flexible.

[0065] In this embodiment, the image acquisition module 20 may be a CMOS module, which is disposed at the front end of the shaft and is used to acquire the surgical scene image of the surgical site; the CMOS module is connected to the image processing module 30 via a cable, and the image processing module 30 is integrated and installed on the image trolley 50. In some designs, the image trolley 50 is provided with wheels to facilitate pushing the image trolley 50 to a suitable position for arrangement and fixing.

[0066] In this embodiment, the outer shell of the shaft is covered by a metal tube, and the outer shell of the handle is covered by a metal shell, wherein both the metal tube and the metal shell can play a role of electromagnetic shielding to prevent interference to the signals therein.

[0067] Specifically, an optical lens and a serial chip are provided inside the shaft. The optical lens is composed of multiple optical lenses. With the help of light source illumination and the light transmission effect of multiple optical lenses of the optical lens, an image can be formed on the photosensitive surface of the image acquisition module 20 (i.e., CMOS module).

[0068] In one embodiment of the present application, the transmission cable includes a signal cable and a power supply cable, and the signal cable connects the image acquisition module 20 and the image processing module 30, and is used to transmit an image signal or a control signal, or a combination of the two signals therebetween. Specifically, when one signal cable is used, the image signal and the control signal are transmitted through the same signal cable, that is, a combination of the two signals. When two signal cables are used, the image signal is transmitted through one signal cable, and the control signal is transmitted through another signal cable. The latter two signals are transmitted separately, which can reduce interference between the signals.

[0069] Exemplarily, the signal cable adopts a coaxial cable or a twisted pair cable, and the outer layer of the coaxial cable or the twisted pair cable is set as a metal shielding layer.

[0070] Specifically, the CMOS module converts the optical signal into a MIPI signal, the serial chip converts the MIPI signal into a serial coaxial signal or a twisted pair differential signal, and the serial coaxial signal or the twisted pair differential signal is transmitted to the image processing module 30 via a coaxial cable or a twisted pair composite cable.

[0071] During the signal transmission process, the high-speed video signal, that is, the serial coaxial signal or the twisted pair differential signal is electromagnetically shielded by the metal tube and the metal casing inside the shaft and the handle. The high-speed video signal is electromagnetically shielded by the metal shielding layer of the cable when transmitted between the handle and the image processing module 30, so as to solve the problem of interference with the high-speed video signal and causing excessive radiation. In this way, the reliability of image information transmission can be fully guaranteed to improve the anti-interference ability and the transmission effect of the transmission cable.

[0072] In this embodiment, the power supply cable connects the image acquisition module 20 and the image processing module 30, so as to transmit the power signal to the image acquisition module 20 and the image processing module 30 after passing through the first isolation module 40, thereby providing power to both.

[0073] Reference Figure 2The first isolation module 40 includes at least an isolation transformer 41, a filter 42 and an AC / DC converter 43; the input end of the isolation transformer 41 is used to be connected to the power input port to achieve electrical isolation from the grid power supply; the filter 42 is connected between the isolation transformer 41 and the AC / DC converter 43, and is used to filter out interference signals in the grid power supply; the AC / DC converter 43 is used to convert alternating current into direct current.

[0074] The image processing module 30 is placed in the image trolley 50. The image trolley 50 is provided with a power input port. The network power supply supplies power to the image trolley 50 through the power input port of the image trolley 50. After the network power enters the image trolley 50, it is directly connected to the isolation transformer 41 and the filter 42. The isolation transformer 41 and the filter 42 perform basic electrical isolation between the network power supply and the image processing module 30, so that the image processing module 30, the endoscope 10 and other components are not subject to electrical interference from the network power supply.

[0075] Specifically, the output end of the isolation transformer 41 supplies power to the AC / DC converter 43, which converts 220V AC power into 12 / 5V DC power and supplies power to the image processing module 30. The image processing module 30, the image trolley 50 and the first isolation module 40 are not designed to share a common ground. An insulation distance of more than 8 mm is set between the ground of the image processing module 30 and the ground of the image trolley 50 and the first isolation module 40.

[0076] Furthermore, the output end of the AC / DC converter 43 is connected to a DC / DC isolator 44 ; an electrical isolation distance is set at both ends of the DC / DC isolator 44 to achieve DC power supply isolation with the image acquisition module 20 and the image processing module 30 .

[0077] It should be noted that the image processing module 30 is connected to the negative pole of the output end of the AC / DC converter 43 or the DC / DC isolator 44 in the first isolation module 40, and the image processing module 30 does not share a common ground with the image trolley 50 and the first isolation module 40. The image trolley 50 and the first isolation module 40 share a common ground, that is, the image processing module 30 is not connected to a common ground with the image trolley 50 and the first isolation module 40.

[0078] In other embodiments, the endoscope camera system further includes a battery module; the battery module is connected between the image acquisition module 20 and the image processing module 30 through a power supply cable, so that the power signal is transmitted to the image acquisition module 20 through the battery module, so as to further play the role of electrical isolation. Specifically, the battery module can be set at the handle position.

[0079] Reference Figure 3The image processing module 30 includes a main computing unit 31, magnetic beads 32, a network port to optical fiber unit 33 and a HDMI to optical fiber unit 34; the output end of the first isolation module 40 is connected to the main computing unit 31 through the magnetic beads 32; the network port to optical fiber unit 33 and the HDMI to optical fiber unit 34 are arranged in parallel, and one end of each is respectively connected to the main computing unit 31, and the other end of each is respectively used to connect to the surgical robot.

[0080] Specifically, the 12 / 5V DC power output by the first isolation module 40 is used to power the main computing unit, the network port to optical fiber unit, and the HDMI to optical fiber unit through the magnetic beads 32 of the image processing module 30. The magnetic beads 32 can further filter out high-frequency interference signals in the 12 / 5V DC power.

[0081] The network port to optical fiber unit 33 converts the network communication electrical signal between the image processing module 30 and the surgical robot into an optical signal, which is transmitted through optical fiber; the HDMI to optical fiber unit 34 converts the HDMI video signal generated by the image processing module 30 into an optical signal, which is transmitted to the surgical robot through optical fiber, for imaging of the surgical robot's main hand display. The network port to optical fiber unit 33 and the HDMI to optical fiber unit achieve complete electrical isolation between the image processing module 30 and the surgical robot.

[0082] In other embodiments, the aforementioned isolation module may be replaced by an electrostatic absorption module. Specifically, the metal tube, metal shell and metal shielding layer of the endoscope 10 and the transmission cable are connected to the electrostatic absorption module in the image processing module 30, and the electrostatic absorption module is connected to the ground of the image processing module 30 to absorb the static electricity existing on the tube wall, handle and transmission cable of the electronic endoscope.

[0083] Exemplarily, the static electricity absorption module may adopt a capacitor device that can absorb static electricity.

[0084] Please continue to refer to Figure 3 The endoscope camera system also includes a second isolation module 60, which is arranged at the ends of the power supply cable connected to the image acquisition module 20 and the image processing module 30 respectively, and is used to shield the interference waveform generated by the electromagnetic radiation acting on the power supply cable. Among them, the second isolation module 60 includes a DC / DC isolator or a filter. Such a setting can filter out the influence of the interference waveform generated by the electromagnetic radiation in the space during the long-distance transmission of the cable on the power supply signal, and at the same time, the module can shield the influence of static electricity on the cable on the image acquisition module 20 and the image processing module 30.

[0085] In this embodiment, since the first isolation module 40 is connected to the image processing module 30 and is electrically isolated from the image processing module 30 and the image acquisition module 20, the image processing module 30 and the image acquisition module 20 can be protected from electrical interference from the mains power supply; when the transmission cable adopts a coaxial cable or a twisted pair cable to achieve long-distance transmission requirements, a second isolation module 60 is provided at the ends of the power supply cable respectively connected to the image acquisition module 20 and the image processing module 30, which can not only further shield the power supply signal from the interference waveform generated by the electromagnetic waves in the space during the transmission process of the power supply cable, but also shield the static electricity on the power supply cable from the image acquisition module 20 and the image processing module 30; on this basis, the signal cable connects the image acquisition module 20 and the image processing module 30 to transmit the image signal and / or the control signal therebetween, and the power supply cable is used to transmit the power supply signal. Transmitting different signals through different cables can further reduce the interference of other signals on the signal on the power supply cable. On the premise that the signal on the power supply cable reaches the lowest interference, coupled with the electrical isolation effect of the first and second isolation modules, electrical isolation can be achieved to the greatest extent, thereby improving the safety of the system.

[0086] In short, this embodiment can achieve a better electrical isolation effect. Through the joint action of the first isolation module 40, the second isolation module 60, the independent setting of the power supply cable and the signal cable, and the use of coaxial cable or twisted pair cable to transmit signals, while meeting the long-distance transmission requirements, it can both reduce signal interference and achieve electrical isolation.

[0087] It should be noted that when the transmission cable is long, the electromagnetic waves in the space (electromagnetic waves generated by devices other than the product itself, such as mobile phones, motors or switching power supplies, etc.) will form interference waveforms again. Therefore, on the premise of achieving electrical isolation through the first isolation module 40, adding a second isolation module 60 can further achieve electrical isolation.

[0088] Reference Figure 4 This embodiment also provides a signal transmission method, which is applied to an endoscope camera system. The system includes an image acquisition module 20, an image processing module 30 and an isolation module. The image acquisition module 20, the image processing module 30 and the isolation module are communicatively connected. The method includes:

[0089] S10, receiving a power supply signal from an external power supply;

[0090] S20, electrically isolating and processing the network power signal through the first isolation module 40 to obtain a power supply with a required voltage;

[0091] S30, filtering the high-frequency components in the DC power supply and transmitting them to the image acquisition module 20 and the image processing module 30 respectively, wherein during the transmission to the image acquisition module 20, the electromagnetic wave interference in the space is filtered through the second isolation module 60.

[0092] An isolation module is used to achieve electrical isolation between the image acquisition module 20, the image processing module 30 and the mains power supply. The mains power supply provides a power supply with an appropriate voltage to the image acquisition module 20 and the image processing module 30 after passing through the isolation module, and is electrically isolated from the image acquisition module 20 and the image processing module 30.

[0093] Further, see Figure 5 , the step S20 of electrically isolating and processing the network power signal to obtain a power supply of the required voltage specifically includes:

[0094] S21, isolating and transforming the grid power signal through the isolation transformer 41;

[0095] S22, performing interference signal filtering processing on the grid power signal after the isolation and transformation processing;

[0096] S23, performing an AC-to-DC conversion operation on the filtered mains power signal to obtain a DC power supply of a required voltage.

[0097] In this embodiment, a power input port is provided on the imaging trolley 50 , and the network power enters the isolation module through the power input port of the imaging trolley 50 .

[0098] Specifically, after the mains power enters through the power input port, it first enters the isolation transformer 41. The function of the isolation transformer 41 is to achieve basic electrical isolation between the image acquisition module 20 and the image processing module 30 and the mains power;

[0099] Then, the image acquisition module 20 and the image processing module 30 are filtered out through the filter 42. The filter 42 is used to further filter out interference signals in the network power supply to prevent the interference signals in the network power supply from interfering with the image acquisition module 20 and the image processing module 30. After passing through the filter 42, the image acquisition module 20 and the image processing module 30 enter the AC / DC converter 43. The AC / DC converter 43 converts the 220V AC power supply into the 5V, 12V, and 24V DC power supply required by the image acquisition module 20 and the image processing module 30, and further enhances the electrical isolation effect between the image acquisition module 20 and the image processing module 30 and the 220V network power supply.

[0100] Furthermore, the power supply enters the DC / DC isolator 44 after passing through the AC / DC converter 43. This module can realize the isolation of the DC power supply. At the same time, sufficient electrical isolation distance is set at both ends of the DC / DC isolator 44. Through this module, the electrical isolation of the image acquisition module 20, the image processing module and the metal shell of the image trolley 50 is realized; after passing through the DC / DC isolator 44, the power supply passes through the magnetic beads 32. The magnetic beads 32 can filter the high-frequency components in the DC power supply to ensure that the power supply signal waveform of the image acquisition module 20 is smooth, thereby ensuring the stable acquisition and output of the high-speed signal of the image acquisition module 20.

[0101] Furthermore, a power supply DC / DC isolation and filtering module is added at each end of the power supply cable, i.e., at the connection between the cable and the handle and the image processing module. The function of this module is to filter out the interference waveform of the power supply signal generated by electromagnetic radiation in the space during the cable transmission process. At the same time, this module shields the static electricity on the cable from affecting the image acquisition module 20 and the image processing module 30. At the same time, the network communication between the image processing module 30 and the surgical robot is transmitted through optical fiber, realizing complete electrical isolation between the image processing module 30 and the surgical robot.

[0102] This embodiment also provides an electronic device, including a processor and a memory, wherein the memory stores computer executable instructions that can be executed by the processor, and the processor executes the computer executable instructions to implement the steps of the signal transmission method of the aforementioned embodiment.

[0103] An embodiment of the present application also provides a computer-readable storage medium, which stores computer-executable instructions. When the computer-executable instructions are called and executed by a processor, the computer-executable instructions prompt the processor to implement the above method.
