Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a shadowless lamp suitable for thoracic surgery. Background Technology

[0002] The shadowless lamp is a core piece of equipment for surgical lighting in the medical device field. Through the coordinated emission of multiple LEDs and optimized optical design, it effectively eliminates shadows in the surgical area, providing surgeons with a clear and uniform lighting environment. This helps surgeons accurately identify tissue layers, blood vessel pathways, and lesion sites, making it a crucial guarantee for the smooth execution of various surgical procedures, including thoracic surgery. In thoracic surgery, the lighting effect of the shadowless lamp directly affects the surgeon's judgment of the surgical field, especially in delicate procedures (such as vascular anastomosis and tumor resection). Stable and appropriate lighting is key to reducing surgical risks and improving surgical precision.

[0003] Based on the above, the inventors have discovered the following problems: current shadowless lamps are not convenient for adjusting the illumination range and brightness. Some shadowless lamps have a fixed illumination range, which can only meet the needs of a single surgical scenario and cannot be flexibly switched according to the type of surgery. Thoracic open-chest surgery requires focused local high-brightness illumination of the incision area to clearly present the details of deep tissues; while thoracoscopic surgery requires the operation instruments to move over a large range, requiring large-area uniform illumination to cover the surgical field. Traditional shadowless lamps are difficult to adapt to both surgical scenarios at the same time.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a shadowless lamp suitable for thoracic surgery, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a shadowless lamp suitable for thoracic surgery to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A shadowless lamp suitable for thoracic surgery includes a support assembly and a shadowless lamp body. The shadowless lamp body includes a housing connected to the support assembly. A second auxiliary lamp board is installed inside the housing, a first auxiliary lamp board is installed inside the second auxiliary lamp board, and a main lamp board is installed inside the first auxiliary lamp board. A light-transmitting plate is installed on the bottom surface of the housing. A beam adjustment module and a brightness adjustment module are respectively installed on the top surface of the main lamp board. A driver module is installed on one side of the beam adjustment module. The main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board are respectively connected to the driver module via wires. A PWM module is installed on one side of the brightness adjustment module. The main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board are respectively connected to the PWM module via wires.

[0007] The beneficial effects of adopting the above-mentioned further solution are that, by nesting the main lamp panel, the first auxiliary lamp panel, and the second auxiliary lamp panel within the housing, the beam range can be flexibly switched by relying on the combination of different lamp panels. In focused mode, only the main lamp panel is activated, meeting the high-brightness concentrated illumination requirements for local fine operations in thoracic open-chest surgery; in non-focused mode, the main lamp panel, the first auxiliary lamp panel, and the second auxiliary lamp panel are activated simultaneously, expanding the illumination coverage and adapting to scenarios requiring large-area uniform illumination in thoracoscopic surgery; the beam adjustment module directly controls the main lamp panel, the first auxiliary lamp panel, and the second auxiliary lamp panel through the drive module. The brightness adjustment module uses a PWM module to precisely control the current of the main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board. The core of the PWM module is to generate pulse electrical signals with different duty cycles (duty cycle is the ratio of the high-level duration within one pulse cycle to the total cycle). The brightness of the main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board is directly proportional to the average current passing through them. Therefore, the higher the duty cycle, the longer the high-level duration, the greater the average current flowing through the lamp beads per unit time, and the higher the brightness. The lower the duty cycle, the smaller the average current, and the lower the brightness. This achieves brightness control.

[0008] Furthermore, optical sensors are installed on one side of the bottom surface near the center of the main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board, and photoelectric sensors are installed on the other side of the bottom surface near the center of the main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board. The optical sensors are connected to the drive module, and the photoelectric sensors are connected to the PWM module.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the photoelectric sensor monitors the actual brightness in real time and feeds the data back to the control center through the wireless communication module. The control center compares the actual brightness with the target brightness. If there is a deviation (such as the actual brightness not reaching the target value), it sends a correction signal to the PWM module to fine-tune the duty cycle until the actual brightness matches the target brightness, forming a closed-loop adjustment. At the same time, the optical sensor monitors the beam range and distribution state of each lamp panel in real time and feeds the data back to the control center through the wireless communication module. The control center compares it with preset beam standard parameters (such as the beam diameter in focused mode and the illumination uniformity threshold in non-focused mode). If a deviation is found (such as insufficient brightness in the edge area when non-focused, or the beam range not reaching the preset value), it sends a correction command to the beam adjustment module, forming a closed-loop adjustment.

[0010] Furthermore, it also includes a control component, which includes a touch screen control panel, and the touch screen control panel is provided with a beam adjustment plus button, a beam adjustment minus button, a brightness adjustment plus button, and a brightness adjustment minus button.

[0011] The beneficial effects of adopting the above-mentioned further solution are that by setting up beam adjustment plus, beam adjustment minus, brightness adjustment plus, and brightness adjustment minus buttons on the touch screen control panel, the operator can achieve function control through intuitive button operation; the beam adjustment button can quickly switch the lamp panel combination mode (e.g., pressing the beam adjustment plus button increases the number of lamp panels activated to expand the beam range, and pressing the beam adjustment minus button decreases the number of lamp panels activated to narrow the beam range); the brightness adjustment button can directly increase or decrease the brightness of each lamp panel without the need for complex operation logic.

[0012] Furthermore, an instruction encoding module is installed on one side of the inside of the touch screen control panel, and a control hub is set near the bottom of the inside of the touch screen control panel. The beam adjustment plus button, beam adjustment minus button, brightness adjustment plus button, and brightness adjustment minus button are connected to the input end of the instruction encoding module through wires. The output end of the instruction encoding module is connected to one input end of the control hub through wires. The control hub is wirelessly connected to the beam adjustment module and the brightness adjustment module through a wireless communication module.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the instruction encoding module can convert the physical signals of the touch screen buttons into digital instructions that the system can recognize, ensuring that the control center can accurately receive control instructions; as the core processing unit, the control center can integrate instructions and transmit them to the beam adjustment module and brightness adjustment module through the wireless communication module, eliminating the need for complex wiring and simplifying the connection structure between the shadowless lamp body and the control components.

[0014] Furthermore, a sound groove is provided on one side of the touch screen control panel, and a microphone array is provided inside the touch screen control panel near the sound groove. A voice preprocessing module is installed inside the touch screen control panel below the microphone array. A voice recognition module is provided on one side of the voice preprocessing module. The voice preprocessing module is connected to the microphone array and the voice recognition module. The output end of the voice recognition module is connected to another input end of the control center through a wire.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the opening of the sound slot can improve the efficiency of the microphone array in collecting voice commands and reduce the interference of operating room environmental noise; after the microphone array collects the surgeon's voice, the voice preprocessing module reduces noise and filters the signal to optimize it, and then the voice recognition module converts the voice into control commands and transmits them to the control center to realize voice control operation. During the operation, the lighting parameters can be adjusted without touching the touch screen control panel.

[0016] Furthermore, the control center is wirelessly connected to the output terminals of several optical sensors and several photoelectric sensors via a wireless communication module.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the control center consists of core hardware (such as a microcontroller MCU or PLC, with supporting power supply, filtering, and storage circuits), functional software (including instruction parsing, closed-loop control, task management, and other programs), and an integrated wireless communication module (such as a Bluetooth or Wi-Fi module). The control center receives feedback data from optical and photoelectric sensors through the wireless communication module. The control center can quickly compare the actual lighting parameters (beam range, brightness) with the target parameters. If there is a deviation, it will promptly send adjustment commands to the beam adjustment module and brightness adjustment module to form a closed-loop control, ensuring that the lighting effect is always accurately adapted to the surgical needs.

[0018] Furthermore, the support assembly includes a connecting frame, a first rotating frame is mounted on one side of the bottom surface of the connecting frame, a second rotating frame is rotatably connected to one end of the first rotating frame, the housing is disposed inside the second rotating frame, and the outer wall of the housing is rotatably connected to the inner wall of the second rotating frame.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the connecting frame provides the installation base for the entire shadowless lamp, the first rotating frame can rotate horizontally around the connecting frame, the second rotating frame can rotate at multiple angles around the first rotating frame, and the shell can rotate freely within the second rotating frame; through the multi-dimensional rotating structure, the surgeon can flexibly adjust the illumination angle and position of the shadowless lamp body.

[0020] Furthermore, a connecting column is installed on the outer wall of the other end of the first rotating frame, and the outer wall of the connecting column is fixedly connected to the outer wall of the touch screen control panel.

[0021] The advantage of adopting the above-mentioned further solution is that the touch screen control board is fixed on the first rotating frame by the connecting column, thereby supporting the control components.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This shadowless lamp suitable for thoracic surgery, when the lamp body is turned on, the main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board inside the housing can be activated in different combinations according to the surgical needs: the beam adjustment module controls the start and stop status of each lamp board through the drive module; if focused illumination is required, only the main lamp board is activated; if wide-area illumination is required, the main lamp board, the first auxiliary lamp board, and the second auxiliary lamp board are activated simultaneously, and the light is emitted through the light-transmitting plate on the bottom surface; the brightness adjustment module regulates the LED current of each lamp board through the PWM module; when the brightness needs to be adjusted, the PWM module outputs pulse signals with different duty cycles to change the current flowing through the lamp beads. The average current enables precise brightness adjustment, meeting the illumination intensity requirements of open-chest or thoracoscopic surgery. When the surgeon operates the beam adjustment plus, beam adjustment minus, brightness adjustment plus, and brightness adjustment minus buttons on the touchscreen control panel, the button signals are transmitted to the instruction encoding module, converted into digital instructions, and sent to the control center. If a voice instruction is issued, the microphone array collects the voice through the sound slot, which is then noise-reduced by the voice preprocessing module and converted into an instruction by the voice recognition module before being transmitted to the control center. The control center, as the core processing unit, can integrate the instructions and transmit them to the beam adjustment module and brightness adjustment module via the wireless communication module.

When the operator operates the beam adjustment plus button, beam adjustment minus button, brightness adjustment plus button, and brightness adjustment minus button on the touch screen control panel 31, the button signal is transmitted to the instruction encoding module 32, converted into a digital instruction, and sent to the control center 36. If a voice instruction is issued, the microphone array 33 collects the voice through the sound slot, which is then noise-reduced by the voice preprocessing module 34 and converted into an instruction by the voice recognition module 35, and transmitted to the control center 36. The control center 36, as the core processing unit, can integrate instructions and transmit them to the beam adjustment module 25 and brightness adjustment module 210 via the wireless communication module. The adjustment module 28 and photoelectric sensor 210 monitor the actual brightness in real time and feed the data back to the control center 36 via the wireless communication module. The control center 36 compares the actual brightness with the target brightness. If there is a deviation, it sends a correction command to the brightness adjustment module 28.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 This utility model provides a technical solution: the support component 1 includes a connecting frame 11, a first rotating frame 12 is mounted on one side of the bottom surface of the connecting frame 11, a second rotating frame 13 is rotatably connected to one side of one end of the first rotating frame 12, a housing 21 is disposed inside the second rotating frame 13, the outer wall of the housing 21 is rotatably connected to the inner wall of the second rotating frame 13, a connecting column is mounted on the outer wall of the other side of one end of the first rotating frame 12, and the outer wall of the connecting column is fixedly connected to the outer wall of the touch screen control panel 31; after the support component 1 is fixedly installed by the connecting frame 11, the first rotating frame 12 can rotate around the connecting frame 11, the second rotating frame 13 can rotate around the first rotating frame 12, and the housing 21 can rotate inside the second rotating frame 13, thereby realizing multi-dimensional angle adjustment of the shadowless lamp body 2, so that the shadowless lamp can be precisely aimed at the surgical area. See also Figure 3 As shown, a connector 14 is mounted on the top surface of the connecting frame 11 for connection with external structural components. The other end of the first rotating frame 12 is connected to the connecting frame 11 via a first damping shaft 15, which facilitates adjustment of the rotation angle of the first rotating frame 12 and keeps it fixed at a specified angle. One end of the first rotating frame 12 has a second damping shaft 16 and a third damping shaft 17. The second rotating frame 13 is mounted on the second damping shaft 16, and the connecting column is mounted on the third damping shaft 17. This allows for adjustment of the angle between the second rotating frame 13 and the connecting column, and also allows them to be kept at a fixed angle. The first damping shaft 15 and the second damping shaft 16 provide significant resistance to maintain the stability of the shadowless lamp body 2 during use.

[0032] In other embodiments, the first damping shaft 15, the second damping shaft 16, and the third damping shaft 17 can all be replaced by a rotating structure. For example, the rotating structure includes a fixed shaft and a rotating sleeve rotatably sleeved on the outside of the fixed shaft. A threaded hole is provided on the side wall of the rotating sleeve, and a locking bolt is provided in the threaded hole. By tightening the locking bolt, the locking bolt presses against the fixed shaft, thereby locking the position of the rotating sleeve. The first rotating frame 12, the second rotating frame 13, and the connecting column are all connected and fixed to the corresponding rotating sleeve.

[0033] Specifically, the working principle of this shadowless lamp suitable for thoracic surgery is as follows: During use, after the support assembly 1 is fixedly installed via the connecting frame 11, the first rotating frame 12 rotates around the connecting frame 11, the second rotating frame 13 rotates around the first rotating frame 12, and the housing 21 rotates within the second rotating frame 13, achieving multi-dimensional angle adjustment of the shadowless lamp body 2, allowing the shadowless lamp to be precisely aimed at the surgical area. When the surgeon operates the beam adjustment plus button, beam adjustment minus button, brightness adjustment plus button, and brightness adjustment minus button on the touchscreen control panel 31, the button signals are transmitted to the finger... The encoding module 32 converts the commands into digital instructions and sends them to the control center 36. If a voice command is issued, the microphone array 33 collects the voice through the sound slot, which is then processed by the voice preprocessing module 34 for noise reduction and the voice recognition module 35 for conversion into a command, which is then transmitted to the control center 36. The control center 36, as the core processing unit, can integrate commands and transmit them to the beam adjustment module 25 and the brightness adjustment module 28 via a wireless communication module. The beam adjustment module 25 controls the start / stop status of each light panel through the drive module 26. For focused lighting, only the main light panel 22 is activated; for large-area lighting... For ambient lighting, the main light panel 22, the first auxiliary light panel 23, and the second auxiliary light panel 24 are activated simultaneously, with light emitted through the bottom light-transmitting plate. The brightness adjustment module 28 controls the LED current of each light panel through the PWM module 29. When brightness adjustment is needed, the PWM module 29 outputs pulse signals with different duty cycles to change the average current flowing through the LED beads, achieving precise brightness adjustment to meet the lighting intensity requirements of open-chest surgery or thoracoscopic surgery scenarios. The photoelectric sensor 210 monitors the actual brightness in real time and feeds the data back to the control center 36 via the wireless communication module. The control center 36 compares the actual brightness with the target brightness. If there is a deviation, it sends a correction command to the brightness adjustment module 28. The PWM module 29 receives the correction signal and fine-tunes the duty cycle until the actual brightness matches the target brightness, forming a closed-loop adjustment. At the same time, the optical sensor 27 monitors the beam range and distribution status of each lamp panel in real time and feeds the data back to the control center 36 through the wireless communication module. The control center 36 compares it with the preset beam standard parameters. If a deviation is found, it sends a correction command to the beam adjustment module 25, forming a closed-loop adjustment.

[0034] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
