Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a shadowless lamp. Background Technology

[0002] In modern surgery, surgical lights, as crucial medical equipment, often need to be adjusted during the procedure to meet different lighting needs. However, the handles and other contact parts of the surgical light can become pathways for bacterial transmission, increasing the risk of surgical infection. Traditional surgical light adjustment methods primarily use manual contact adjustment, which has the following drawbacks: 1. Poor user experience: Prolonged use of manual buttons or handles can degrade the tactile feel of the buttons, potentially causing stiffness or weak rebound, affecting the smoothness and accuracy of operation, thus reducing the user experience for surgical staff. 2. Poor anti-interference capability: High-frequency electrosurgical units and other electrical equipment are often used in operating rooms. The electromagnetic interference generated by these devices can affect the buttons or handles of the surgical light, causing accidental on / off activation. This electromagnetic interference not only affects the normal operation of the equipment but may also distract medical staff, increasing the risk of operational errors. 3. Risk of cross-infection: During surgery, medical staff frequently touch the adjustment components. Direct contact with buttons or handles can easily lead to cross-infection, especially when surgical light adjustments are frequent, making the transmission of bacteria even more apparent.

[0003] Currently, some high-end surgical lights utilize wireless remote control for contactless adjustment. This design reduces direct contact, lowers the risk of bacterial transmission, and improves operational convenience. However, this wireless remote control method still presents several challenges: 1. Poor signal stability: Operation of wireless remote control devices relies on wireless signals. However, the complex environment of an operating room, including walls, equipment, and other objects, can obstruct signal transmission, leading to signal instability or failure. Furthermore, electromagnetic interference between strong and weak electrical devices can affect the stability and reliability of the remote control signal, impacting the precise adjustment of the surgical light. 2. Easily lost remote control: Wireless remote controls typically require handheld operation. Due to the high frequency of operation by medical staff during surgery, remote controls are easily lost and may not conform to operational habits during intense procedures, increasing inconvenience. 3. Safety hazards: The open signal of wireless remote control devices may be interfered with by other wireless devices, causing abnormal signal fluctuations or misoperation by unauthorized devices, leading to unsafe operational risks. This potential safety hazard could threaten the stability of the surgical procedure and the operational safety of medical staff.

[0004] Therefore, although existing adjustment methods have improved the ease of operation and infection control of surgical lights to some extent, many problems still need to be solved, especially in terms of signal stability, equipment safety, and user experience. Therefore, developing a more efficient, safe, and stable surgical light adjustment method has significant clinical application value. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned defects of the prior art and thus provide a shadowless lamp.

Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of the shadowless lamp provided in an embodiment of the present utility model. Detailed Implementation

[0016] The technical solution provided by this utility model will be further illustrated below with reference to the embodiments.

[0017] Example 1

[0018] The shadowless lamp provided in this embodiment, such as Figure 1 As shown, it mainly consists of a shadowless lamp body 1, a light source module, a gesture circuit board 2, a main control board 3, and a driver board 4. The gesture circuit board 2, the main control board 3, and the driver board 4 are all integrated inside the shadowless lamp body 1. Each component is mechanically assembled and connected to the circuit to work together to achieve precise lighting control.

[0019] The main body of the shadowless lamp 1 is ring-shaped (or has a shape adapted to the needs of surgical lighting). Its interior is divided into a first accommodating cavity 1, a second accommodating cavity 2, and a third accommodating cavity 4 by a partition, which are used to install the driver board 4, the main control board 3, and the gesture circuit board 2, respectively. The third accommodating cavity 4 has a sensing window 3, and a light-transmitting protective plate is embedded in the sensing window 3.

[0020] Gesture Circuit Board 2: Gesture circuit board 2 is fixedly installed in the third accommodating cavity 4, integrating a gesture recognition sensor (such as an infrared array sensor or a miniature camera module) and a signal preprocessing circuit. The sensing direction of the gesture recognition sensor faces the sensing window 3 to ensure effective acquisition of external gesture signals. Gesture circuit board 2 is connected to the main control board 3.

[0021] Main control board 3: The main control board 3 is embedded in the second accommodating cavity 2 and serves as the system control center. The main control board 3 is connected to the drive board 4.

[0022] Drive board 4: Drive board 4 is installed in the first accommodating cavity 1 near the light source module, and it is connected to the light source module through wires.

[0023] Light source module: The light source module is evenly distributed along the annular circumference of the main body of the shadowless lamp to provide the uniform, shadowless illumination required for the surgical area.

[0024] In surgical applications, medical staff make various types of hand gestures outside the sensing window 3. The gesture circuit board 2 recognizes these gestures and converts them into corresponding gesture signals, which are then sent to the main control board 3. These gesture types include wake-up gestures, function switching gestures, and parameter adjustment gestures. The main control board 3 receives and processes the gesture signals; the driver board 4 adjusts the parameters of the shadowless lamp's light source module based on the gesture signals processed by the main control board 3, achieving real-time control of the lighting status.

[0025] The following will explain the specific working process of the shadowless lamp, but it is worth noting that the control logic of the gesture signal is a technical means well known to those in the field.

[0026] The main control board 3 can be used to determine whether the gesture signal is a wake-up gesture. If it is a wake-up gesture, subsequent gesture actions are allowed to switch functions or adjust parameters; if it is not a wake-up gesture, the signal is ignored.

[0027] If the gesture is a wake-up gesture, the main control board 3 continues to receive gesture signals sent by the gesture circuit board 2 and determines the type of the gesture signal to be received. If the received gesture signal is a function switching gesture, a corresponding function switching command is sent to the driver board 4, causing the driver board 4 to switch to the corresponding function. Then, it receives parameter adjustment gesture signals sent by the gesture circuit board 2 and sends the corresponding parameter adjustment command to the driver board 4, causing the driver board 4 to adjust the parameters of the current function according to the parameter adjustment command. If the received gesture signal is a parameter adjustment gesture signal, the corresponding parameter adjustment command is sent to the driver board 4, causing the driver board 4 to adjust the parameters of the current function according to the parameter adjustment command. The functions include: brightness function, color temperature function, and light spot function. The parameter adjustment commands include: increasing parameters and decreasing parameters.

[0028] The wake-up gesture can be a forward gesture. Forward gesture: used to wake up the gesture recognition function and activate subsequent gesture operations.

[0029] The function switching gestures include an upward gesture and a downward gesture. The upward gesture corresponds to switching to the previous function, and the downward gesture corresponds to switching to the next function. The upward and downward gestures are used to switch the main functions of the shadowless lamp. Specifically, the upward gesture switches to the light spot adjustment function, while the downward gesture switches to the color temperature adjustment function. For example, in illuminance adjustment mode, the upward gesture switches to light spot adjustment, and the downward gesture switches to color temperature adjustment, allowing users to quickly switch between different adjustment modes.

[0030] The parameter adjustment gestures include a left gesture and a right gesture. The left gesture corresponds to a parameter reduction command, and the right gesture corresponds to a parameter increase command. The left and right gestures are used to adjust the parameters of the shadowless lamp, specifically adjusting the illuminance level. In illuminance mode, the left gesture decreases the illuminance by one level, while the right gesture increases the illuminance by one level, allowing users to make precise lighting adjustments as needed.

[0031] The gesture types also include a turn-off gesture. Upon receiving a turn-off gesture signal, the main control board 3 turns off the shadowless lamp. The turn-off gesture can be a backward gesture, used to disable the gesture recognition function and stop subsequent operations. Forward and backward gestures, through explicit triggering methods, make system startup and shutdown more flexible and efficient.

[0032] These gestures allow users to efficiently and intuitively adjust various functions of the surgical light.

[0033] The main control board 3 continues to receive gesture signals within a preset time period after sending the corresponding parameter adjustment command to the driver board 4; if no gesture signal is received within the preset time period, it enters a sleep state.

[0034] The shadowless lamp also includes a display panel for displaying the current function and for displaying gesture prompts.

[0035] Compared with the prior art, this utility model has at least the following advantages:

[0036] Reduce the risk of cross-infection: This invention uses gesture recognition, eliminating the need for medical staff to directly touch the equipment, thus significantly reducing the risk of cross-infection caused by frequent touching of the equipment. Especially during surgery, this design is of great significance in ensuring the hygiene and safety of the surgical environment.

[0037] Improving ease of use and efficiency: Gesture control allows medical staff to quickly and intuitively adjust parameters such as brightness, color temperature, and light spot of the surgical light without interrupting the procedure, avoiding problems such as button malfunction and inconvenience that may occur with traditional manual adjustment methods. Gesture recognition offers fast response times and greater ease of operation, significantly improving the efficiency and accuracy of surgical procedures.

[0038] Overcoming signal instability issues: Compared to traditional wireless remote control adjustment methods, this invention does not rely on wireless signal transmission, thus avoiding signal instability or failure caused by external factors such as obstacles and electromagnetic interference, ensuring the stability and reliability of operation.

[0039] Improving the user experience: Gesture control allows medical staff to focus more on the procedure itself during surgery, reducing negative experiences caused by unresponsive buttons or complex operations. Gesture control not only meets the needs of the surgical environment but also effectively reduces the discomfort that traditional manual buttons may cause.

[0040] Enhanced safety: Because the gesture control system does not involve direct contact, it avoids the risk of accidental operation that may occur with buttons or touchscreens in traditional devices. Furthermore, the gesture recognition system is designed to prevent interference from other wireless devices, ensuring the safety and stability of device operation.

[0041] Simplified equipment maintenance and operation: Compared to traditional buttons or remote controls, gesture control systems reduce wear and tear on physical buttons and avoid the hassle of lost remote controls. Furthermore, gesture control aligns with the operating habits of medical staff, allowing them to focus more on surgical procedures without frequently searching for and operating remote-controlled devices.

[0042] In summary, this invention provides a more efficient and safer surgical light gesture adjustment solution by introducing gesture recognition technology, overcoming several shortcomings of traditional technologies and greatly improving the operating experience and safety during surgery.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
