Description

Technical Field

[0001] This utility model relates to the field of surgical shadowless lamp technology, and in particular to a mechanism for adjusting the size of the light spot in a surgical shadowless lamp. Background Technology

[0002] Surgical shadowless lamps are indispensable key equipment in the operating room, and the high-quality illumination they provide is crucial for the smooth progress of surgery. In actual surgery, different surgical types and operational needs require different sizes of light spots. For example, in delicate eye surgeries, a smaller and more precise light spot is needed to focus on tiny surgical sites; while in large-area wound repair surgeries, a larger light spot can provide a wider illumination area.

[0003] However, existing surgical shadowless lamps have many limitations in terms of spot size adjustment. Some shadowless lamps have complex adjustment methods, making it difficult for medical staff to operate quickly and accurately in the stressful surgical environment; some adjustment mechanisms lack sufficient precision and cannot meet the strict requirements of different surgeries for spot size; and some shadowless lamps have limited adjustment ranges, which cannot cover the various spot sizes required for surgery. Therefore, we propose a spot size adjustment mechanism for surgical shadowless lamps. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for adjusting the size of the light spot in a surgical shadowless lamp, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surgical shadowless lamp with adjustable spot size mechanism includes a support plate, a mounting frame fixedly mounted on the top of the support plate, a first motor fixedly mounted on the bottom inner wall of the mounting frame, a control panel module fixedly mounted on the front side of the mounting frame, a display screen above the control panel module, a lead screw fixedly mounted on the output end of the first motor, and a sliding frame threaded onto the outer side of the lead screw.

[0007] By adopting the above technical solution, the control panel module, mounted on the mounting bracket, displays the light spot size parameters and equipment operating status on a visual screen. It allows medical personnel to easily issue light spot adjustment commands via buttons for increasing / decreasing the light spot and inputting preset values. The data acquisition module is responsible for summarizing analog signals from sensors such as temperature and current, which are used to measure the position of the reflector component and the operating status of the lamp head. These signals are then converted into digital signals and transmitted to subsequent modules. The analysis module receives data from the data acquisition module and commands from the control panel, compares the actual and ideal positions of the reflector component, and calculates the operating parameters required to adjust the motor. The microprocessor module, as the core, executes the algorithm generated by the analysis module, sends control commands to the drive module, and coordinates the work of each module to ensure system stability. The drive module, based on the commands, adjusts the rotation of the first and second motors, allowing them to adjust the positions of the aluminum alloy frame and LED beads. It also allows the drive module to control the movement of the reflector inside the aluminum alloy frame.

[0008] As a further improvement to the above solution, a fixed frame is fixedly installed on one side of the sliding frame, a second motor is fixedly installed on the inner side of the fixed frame, and a drive shaft is fixedly installed on the output end of the second motor.

[0009] As a further improvement to the above solution, a mounting plate is fixedly installed on one side of the drive shaft, an aluminum alloy frame is fixedly installed on one side of the mounting plate, and multiple LED beads are fixedly installed on the inner side of the aluminum alloy frame.

[0010] As a further improvement to the above solution, a light-transmitting window is fixedly installed at the bottom of the aluminum alloy frame, and multiple reflectors are fixedly installed on the inner side of the aluminum alloy frame. The reflectors are fixedly installed at the output end of the drive motor.

[0011] As a further improvement to the above solution, a sliding groove is provided on the top of the mounting bracket, and the sliding bracket is slidably installed on the inner side of the sliding groove; as a further improvement to the above solution, a mounting groove is provided on one side of the fixing bracket, and the second motor is fixedly installed on the inner side of the mounting groove.

[0012] By adopting the above technical solution, when the drive module controls the first motor and the second motor, the first motor can drive the lead screw to rotate, and the lead screw can drive the sliding frame, the aluminum alloy frame above, and the LED beads to be raised and lowered. The second motor can drive the mounting plate, the aluminum alloy frame, and the LED beads to be rotated and adjusted through the drive shaft, which makes it easier to adjust the LED beads within a larger range.

[0013] As a further improvement to the above solution, the control panel module is electrically connected to a data acquisition module, the data acquisition module is electrically connected to an analysis module, the analysis module is electrically connected to a microprocessor module, the microprocessor module is electrically connected to a drive module, the drive module is electrically connected to the first motor and the second motor, the control panel module is electrically connected to a communication module, the control panel module is electrically connected to a fault diagnosis and alarm module, and the control panel module is electrically connected to a storage module.

[0014] By adopting the above technical solution, when the reflector moves, the angle between the reflector and the light-transmitting window changes, thereby altering the reflection path and convergence point of the light, and adjusting the size of the light spot. For example, when the reflector moves closer to the light-transmitting window, the convergence point of the light moves forward, and the light spot becomes smaller; conversely, when the reflector moves away from the light-transmitting window, the convergence point of the light moves backward, and the light spot becomes larger. The storage module stores configuration parameters such as preset light spot values ​​for different surgical types, historical operation records, and fault information. The communication module enables connection with other medical equipment or hospital information management systems, transmitting working status and light spot adjustment data to the operating room monitoring system for centralized management. The fault diagnosis and alarm module monitors system operation according to preset rules. Once abnormalities such as motor overload or sensor failure are detected, an audible and visual alarm is immediately triggered, and the fault information is recorded in the storage module.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The surgical shadowless lamp adjustment spot size mechanism of this utility model, when the drive module controls the first motor and the second motor, can drive the lead screw to rotate, and the lead screw can drive the sliding frame and the aluminum alloy frame and LED beads above to adjust the height. The second motor can drive the mounting plate, aluminum alloy frame and LED beads to rotate and adjust through the drive shaft, so that the adjustment range of the LED beads is larger.

[0017] (2) The surgical shadowless lamp of this utility model has a control panel module. This module is set on the mounting frame and displays the light spot size parameters and the working status of the equipment on a visual display screen. The light spot adjustment instructions can be easily issued by medical staff by buttons such as increasing, decreasing the light spot and inputting preset values. The data acquisition module is responsible for summarizing the analog signals from the position of the reflective component and the working status of the lamp head, such as temperature and current, and converting them into digital signals to be transmitted to the subsequent modules.
