Description

Technical Field

[0001] This utility model relates to the field of surgical technology, and in particular to a surgical spotlight. Background Technology

[0002] Spotlights are often used in surgery. They provide a bright and focused light source, allowing doctors to clearly see the surgical area during the procedure. At the same time, the angle and intensity of the spotlight can be adjusted to minimize shadows on the surgical area, thereby effectively improving the precision and safety of the surgery.

[0003] Chinese Patent Publication No. CN115789546A discloses a focusing adjustment device for a multi-source surgical lamp, comprising: a lamp holder, a main lamp cover fixedly connected to the bottom of the lamp holder, an annular groove formed inside the lower surface of the lamp holder, an adjusting seat slidably connected inside the annular groove, a rotating seat fixedly connected to the bottom of the adjusting seat near the main lamp cover, and an inflatable telescopic rod fixedly connected to the bottom of the adjusting seat away from the main lamp cover, and a spotlight fixedly connected to the bottom of the rotating seat; a focusing component, slidably connected to the side wall of the adjusting seat, the focusing component being used to adjust the number and angle of the spotlights, thereby improving the focusing effect of the device; and a dimming component, rotatably connected to the inner wall of the lamp holder, the dimming component being used to adjust the type of light source generated inside the main lamp cover.

[0004] Therefore, while the above-mentioned technical solutions can adjust the angle and light source of the spotlight, they have the following problems: existing surgical lights cannot precisely adjust the light within the surgical area, making it difficult to efficiently provide a comprehensive focused lighting effect. During surgery, it is usually necessary to precisely concentrate the light source at a designated location and adjust the brightness around that designated location in the surgical area as needed. If the surgeon manually adjusts the position, angle, or brightness of the spotlight during the procedure, it is often difficult to achieve the best lighting effect efficiently and precisely. Furthermore, the frequent changes in light during surgery can easily cause discomfort for the surgeon, thus adversely affecting the operation. Utility Model Content

[0030] It is understood that the spotlight of this utility model can be flexibly moved and adjusted to illuminate a designated position, and the illumination range and center can be flexibly adjusted. The spotlight illumination unit 1 consists of a first spotlight assembly 101 and a second spotlight assembly 102 with two central axes overlapping, which respectively position the first designated position (first spotlight assembly 101) and the second designated position (second spotlight assembly 102) to form a main illumination spot and an auxiliary illumination spot, thereby achieving all-round illumination of the surgical area.

[0033] Please see Figure 1 , Figure 3 As shown, Figure 1 This is a front structural diagram of the focused lighting unit of this utility model. Figure 3 This is a schematic diagram of the back structure of the focused lighting unit of this utility model.

[0034] Specifically, the first focusing component 101 includes at least one set of first illumination units and first positioning units; Each group of first lighting units is arranged in a ring, and each group of first lighting units includes at least five lighting lamps; The first positioning unit includes a first positioning beam emitter, which is used to emit a positioning beam to mark a first illumination range and a first illumination center.

[0035] In one specific embodiment, a first positioning beam emitter is used to emit a positioning beam to mark a first illumination range and a first illumination center. The doctor can make precise positioning illumination adjustments by remote control according to the guidance of the emitted positioning beam.

[0036] In practice, the first positioning beam emitter can be a sensor such as a laser emitter. The specific types of sensors involved in the first positioning beam emitter are not limited here, as long as the positioning beam emitter can emit a positioning beam to mark and illuminate the center. Further details will not be provided here.

[0037] The first focusing component 101 of this utility model is provided with at least one set of first annular lighting units, which provides sufficient light while ensuring uniform light distribution. At the same time, by setting a first positioning unit, the positioning beam emitter can emit a positioning beam to mark the lighting center and adjust the lighting area, thereby further ensuring that the surgical area can always obtain the best lighting effect, and enhancing the flexibility and operability of the focusing device.

[0038] Specifically, the second focusing component 102 includes at least two sets of illumination parts and a second positioning unit; Each lighting unit includes at least one row of second lighting units, each row of second lighting units is arranged in an arc, and each lighting unit forms a ring-shaped illumination area, and each row of lighting units includes at least three lighting lamps; The second positioning unit includes a second positioning beam emitter, which is used to emit a positioning beam to mark the second illumination range and the second illumination center.

[0039] In one specific embodiment, the second positioning beam emitter is used to emit a positioning beam to mark the second illumination range and the second illumination center, and the doctor can make precise adjustments to the illumination range through the control remote according to the guidance of the emitted positioning beam.

[0040] In practice, the second positioning beam emitter can be a sensor such as a laser emitter. The types of sensors involved in the second positioning beam emitter are not specifically limited here and will not be elaborated further.

[0041] In this embodiment, the second focusing component 102 includes four groups of lighting sections and a second positioning unit. Each group of lighting sections includes a row of second lighting units, and each row of second lighting units is arranged in a ring. Each group of lighting sections forms a ring-shaped illumination area, and each row of second lighting units includes five lighting lamps.

[0042] In practice, the number of lighting units in the second focusing assembly 102, the number of second lighting units in each group of lighting units, and the number of lighting lamps in each column of second lighting units can be determined according to the actual situation. No specific limit is made here, as long as the second focusing assembly 102 can completely focus light on the designated position of the surgical area. Further details are not provided here.

[0043] The second focusing component 102 of this utility model is provided with at least two sets of lighting units, which can ensure that all important parts in the surgical area receive all-round lighting and sufficient light. At the same time, a second positioning unit is provided to determine the corresponding lighting center, which helps to ensure that the surgical position receives sufficient lighting. Precise global lighting and precise positioning improve the accuracy of lighting, thereby further ensuring that the surgical area always receives the best lighting effect, and enhancing the flexibility and operability of the focusing device.

[0044] Specifically, the first light-concentrating component 101 is circular, and the second light-concentrating component 102 is an annular ring composed of several arcs. The inner diameter of the annular ring of the second light-concentrating component 102 is larger than the diameter of the first light-concentrating component 101.

[0045] It is understood that the first focusing component 101 is the central illumination area of ​​the spotlight, and the second focusing component 102 is arranged around the first focusing component 101. The inner diameter of the second focusing component 102 is the diameter of the inner circle of the arc-shaped illumination part in the second focusing component 102.

[0046] In practice, the range and preferred values ​​of the inner diameter of the second focusing component 102 and the diameter of the first focusing component 101 are not specifically limited here. As long as the inner diameter of the second focusing component 102 is larger than the diameter of the first focusing component 101, and the first focusing component 101 and the second focusing component 102 can achieve complete focused illumination of the surgical area, it will not be elaborated here.

[0047] Specifically, the first focusing component 101 and the second focusing component 102 are provided with a distance adjustment unit 2, which is used to adjust the positional distance between the first focusing component 101 and the second focusing component 102 and the illumination angle of the second focusing component 102.

[0048] Specifically, the adjusting unit 2 includes: The slide rail 201 is used to allow each lighting area to move stably along the slide rail 201 in a direction away from / closer to the first focusing component 101; The first drive motor 203 is used to drive each group of lighting units to move on the slide rail 201 to adjust the connection distance between the first focusing component and the second focusing component. The second drive motor 204 is used to drive the rotating shaft to rotate, thereby driving the second focusing component to rotate axially on the rotating shaft to adjust the illumination angle of the second focusing component; The slider 202 cooperates with the slide rail 201 and is used to slide on the slide rail 201. The slider 202 is connected to the second focusing component 102 by a rotating shaft. A lead screw, which is connected to the slider 202, is used to convert the rotational motion of the first drive motor 203 into linear motion, thereby driving each group of lighting units to move on the slide rail 201.

[0049] It is understandable that the positional distance between the first focusing component 101 and the second focusing component 102 and the illumination angle of the second focusing component 102 can be adjusted by adjusting the distance unit 2, thereby adjusting the illumination area.

[0050] In implementation, the adjustment unit 2 can be either mechanical or electric. For example, a mechanical adjustment can be a slider-rail mechanism, where the slider 202 is connected to the second focusing component 102 via a rotating shaft. The rail 201 provides a stable movement path, and the slider 202 slides freely on the rail 201. By mechanically pushing the slider 202, the connection distance between the first focusing component 101 and the second focusing component 102 can be adjusted. By rotating the rotating shaft, the second focusing component 102 can rotate along the axial direction of the rotating shaft, facilitating the adjustment of the illumination angle of the second focusing component 102. For example, the electric distance adjustment can be a combination of an electric push rod structure and an electric rotation structure. The electric distance adjustment includes a first drive motor 203, a second drive motor 204, a reducer, and a lead screw. The two ends of the electric push rod are connected to two focusing components respectively. The motor rotation drives the lead screw, thereby adjusting the connection distance between the first focusing component 101 and the second focusing component 102. The electric rotation structure includes a first drive motor 203, a second drive motor 204, a rotating shaft, and a reducer. The second drive motor 204 drives the rotating shaft at the connection point of the second focusing component 102 to rotate, thereby adjusting the illumination angle of the second focusing component 102. The distance adjustment method and related structure of the distance adjustment unit 2 can be determined according to actual conditions and will not be elaborated here.

[0051] Specifically, the distance adjustment unit 2 also includes a limit protection switch, which is disposed at both ends of the slide rail 201 to prevent the lighting area from exceeding the preset lighting range.

[0052] It is understood that this invention precisely adjusts the position of each lighting component on the slide rail 201 by driving a motor, thereby changing the connection distance between the first focusing component 101 and the second focusing component 102. Simultaneously, by driving the rotating shaft on the slider 202, the lighting angle of the second focusing component 102 is adjusted, achieving flexible adjustment of the lighting range. Furthermore, the limit protection switches provided at both ends of the slide rail 201 effectively prevent the lighting area from exceeding the preset lighting range, thus affecting the focused lighting effect.

[0053] In implementation, the number of slide rails 201 can be determined according to the number of lighting units. No specific limit is made here, as long as the lighting units can move stably along the slide rails 201. Further details are omitted here. The rotation angle between the slider 202 and the second focusing component 102 can be determined according to the actual situation. No specific limit is made here.

[0054] This utility model is equipped with an adjustment unit 2, which uses a slide rail 201, a slider 202, a first drive motor 203, and a second drive motor 204 to adjust the position and move stably of each lighting part in the second focusing assembly 102. This achieves precise control of the lighting range, ensures the stable movement and positional safety of the lighting parts, and further ensures that the surgical area always receives the best lighting effect. This enhances the flexibility and operability of the equipment and improves the accuracy of the lighting.

[0055] Specifically, this utility model also includes a remote control, which is equipped with an illuminance measuring device to acquire illuminance data of the surgical area in real time.

[0056] The remote control displays the illuminance data and controls the first drive motor 203 and the second drive motor 204 to precisely adjust the position of the lighting unit by controlling the control signals emitted by the buttons on the remote control.

[0057] In one specific embodiment, the control remote includes a microprocessor capable of analyzing illuminance data. The control remote has left and right buttons. Based on the analysis results of the illuminance data, the control remote sends commands to the first drive motor 203 and the second drive motor 204 via the buttons, such as moving left / right or driving the rotating shaft. Upon receiving the commands, the first drive motor 203 and the second drive motor 204 adjust the position of the focused illumination unit 1, such as moving left / right or rotating the second focused illumination component 102, to optimize the illumination effect in the surgical area.

[0058] This invention integrates an illuminance meter and a remote control to acquire illuminance data of the surgical area in real time, and flexibly adjusts the position of the spotlight unit 1 based on the data results, thereby ensuring that the surgical area obtains the best lighting effect, enhancing the flexibility and operability of the spotlighting equipment, and improving the accuracy of the lighting.

[0059] Specifically, this invention uses an LED matrix as the output light source of the spotlight unit 1, and at the same time, a variable reflector is set inside the lamp panel of the spotlight unit 1 to realize the light source processing of the spotlight unit 1 and ensure the spotlight focusing quality during surgery.

[0060] In one specific embodiment, the LED matrix used in the spotlight unit 1 prevents the illuminated area from heating up due to prolonged spotlight illumination. At the same time, a variable reflector is set inside the lamp panel of the spotlight unit 1 so that the light source output by the lighting unit is processed by filtering infrared rays, uniform illumination and shadow compensation. Through the superposition of multi-angle light, the shadow dead corners of the surgical area can be effectively eliminated. At the same time, it avoids the drying or heat damage of the surgical area tissue due to prolonged light source exposure, reduces the stimulation of the doctor's eyes, and reduces visual fatigue during long-term surgery.

[0061] Specifically, the spotlight unit 1 has intelligent adjustment of the size and diameter of the light spot, anti-flicker function, and adjustable color temperature function.

[0062] In one specific embodiment, the spotlight unit 1 can precisely adjust the size and diameter of the light spot according to the received control signal and the illuminance data obtained by the illuminance meter, thereby ensuring that the light intensity matches the procedure in different surgical steps. At the same time, the spotlight has an adjustable color temperature function, which can avoid tissue color distortion caused by low color temperature light (yellowish) and prevent visual fatigue caused by high color temperature light (blueish). In addition, the "flicker-free" characteristic (frequency ≥100Hz) of the spotlight can prevent visual fatigue of surgical staff due to prolonged surgery, thereby improving the quality of surgery.

[0063] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
