Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular, to an endoscope surgical lamp with adjustable color and brightness. Background Art

[0002] Compared with traditional surgical operations, endoscopic surgery only needs to make an incision as small as a keyhole at the position of the patient to be operated, which can meet the needs of surgeons to perform operations, minimizing the damage to human tissues. In related technologies, when performing endoscopic surgery, surgeons need to insert an endoscopic surgical lamp for illumination and an endoscopic camera for imaging into the patient's body through the opened incision. The endoscopic camera will transmit the captured images to an external display, so that surgeons can clearly see the situation inside the patient's body on the display for subsequent operations. However, the illumination effect of existing endoscopic surgical lamps is single, usually only green light or the effect of dimming the light. On the one hand, it cannot compensate for the Color Rendering Index (CRI) of the endoscopic surgical lamp. On the other hand, surgeons are prone to visual fatigue when performing operations under a single-color light for a long time. Content of the Utility Model

[0003] This application provides an endoscopic surgical lamp with adjustable color and brightness, aiming to solve the problems of low color rendering index of endoscopic surgical lamps and easy visual fatigue of surgeons in related technologies.

[0004] To solve the above technical problems existing in related technologies, this application provides an endoscopic surgical lamp with adjustable color and brightness. The endoscopic surgical lamp includes a single-chip microcomputer, a first driving module, and a first endoscopic lamp module. The single-chip microcomputer is electrically connected to the first driving module, and the first driving module is electrically connected to the first endoscopic lamp module. Specifically, the first endoscopic lamp module is used to emit target visible light; the first driving module is used to transmit a driving current to the first endoscopic lamp module under the control of the single-chip microcomputer to drive the first endoscopic lamp module to emit target visible light, and by adjusting the driving current, change the color and / or brightness of the target visible light.

[0005] It can be understood that through the implementation of the above technical solutions of the present application, the single-chip microcomputer is used to control the first driving module, so that the first driving module transmits a driving current to the first endoscope lamp module, so as to drive the first endoscope lamp module to emit the target visible light through the driving current, and the single-chip microcomputer can also be used to control the first driving module to adjust the driving current, so as to change the color and / or brightness of the target visible light. Then, when the endoscope surgical lamp of the present application is applied to endoscopic surgery, the surgeon can issue an instruction to the single-chip microcomputer, and then the single-chip microcomputer can control the first driving module to adjust the driving current according to the received instruction, so as to change the color and / or brightness of the target visible light emitted by the first endoscope lamp module; that is to say, the endoscope surgical lamp of the present application can perform arbitrary adjustment of color and brightness, not only compensating the color rendering index of the endoscope surgical lamp, but also providing lights of multiple colors and multiple brightness levels for the surgeon to choose from, meeting the surgeon's usual eye habits while avoiding visual fatigue caused by the surgeon performing surgery under a single-color light for a long time.

Detailed implementation manners

[0014] In order to make the purpose, technical solutions and advantages of the present application more obvious and understandable, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. It should be understood that the various embodiments of the present application described below are only used to explain the present application and are not used to limit the present application. That is, based on the various embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0015] In the related art, the lighting effect of the endoscope operating lamp is single, usually only green light or the effect of dimming the light. On the one hand, it is impossible to compensate the color rendering index of the endoscope operating lamp (used to measure the ability of the light source to restore the color of an object). On the other hand, surgeons are prone to visual fatigue when performing surgery under a single-color light for a long time. For this reason, in the embodiments below of the present application, an endoscope operating lamp with adjustable color and brightness is proposed to avoid the above-mentioned drawbacks existing in the related art.

[0016] Figure 1It is a structural block diagram of a laparoscopic surgical lamp. In some embodiments, the laparoscopic surgical lamp includes a single-chip microcomputer 100, a first driving module 200, and a first laparoscopic lamp module 300. The single-chip microcomputer 100 is electrically connected to the first driving module 200, and the first driving module 200 is electrically connected to the first laparoscopic lamp module 300. In actual applications, on the one hand, the single-chip microcomputer 100 can control the first driving module 200 to transmit a driving current to the first laparoscopic lamp module 300, so as to drive the first laparoscopic lamp module 300 to emit a target visible light through the driving current. On the other hand, the single-chip microcomputer 100 can control the first driving module 200 to adjust the driving current to change the color and / or brightness of the target visible light. Based on this, during laparoscopic surgery, a surgeon can issue a dimming instruction to the single-chip microcomputer 100, and then the single-chip microcomputer 100 can control the first driving module 200 to adjust the driving current according to the received dimming instruction, thereby changing the color and / or brightness of the target visible light emitted by the first laparoscopic lamp module 300. That is to say, the laparoscopic surgical lamp of the present application can perform arbitrary adjustment of color and brightness, not only compensating the color rendering index of the laparoscopic surgical lamp, but also providing lights of multiple colors and multiple brightness levels for the surgeon to choose from. While meeting the usual eye habits of the surgeon, it also avoids the visual fatigue caused by the surgeon performing surgery under a single-color light for a long time.

[0017] As one of the embodiments, Figure 2 It is another structural block diagram of a laparoscopic surgical lamp. The first laparoscopic lamp module 300 includes a red light unit 310, a green light unit 320, and a blue light unit 330. In actual applications, the red light unit 310 can emit red visible light, the green light unit 320 can emit green visible light, and the blue light unit 330 can emit blue visible light. Based on this, the target visible light emitted by the first laparoscopic lamp module 300 includes any one of red visible light, green visible light, and blue visible light, or at least two of red visible light, green visible light, and blue visible light are mixed to form the target visible light. That is to say, when only the red light unit 310 is working, the target visible light emitted by the first laparoscopic lamp module 300 is red visible light; when only the green light unit 320 is working, the target visible light emitted by the first laparoscopic lamp module 300 is green visible light; when only the blue light unit 330 is working, the target visible light emitted by the first laparoscopic lamp module 300 is blue visible light; when at least two of the red light unit 310, the green light unit 320, and the blue light unit 330 are working, the corresponding at least two visible lights are mixed to produce the target visible light emitted by the first laparoscopic lamp module 300. It can be understood that the three colors of red, green, and blue are called primary colors in the art, and they can produce any color when mixed in different proportions. Then, for the red visible light, green visible light, and blue visible light of the present application, they can also produce target visible light of any color when mixed in different proportions.

[0018] In some implementation manners of this embodiment, Figure 3 The following shows a schematic structural diagram of the first endoscope lamp module. The structures of the red lamp unit 310, the green lamp unit 320, and the blue lamp unit 330 are the same, and they are all as shown in Figure 3 (a), that is: the red lamp unit 310 includes a plurality of series-connected red lamp bead groups 311 (4 red lamp bead groups 311 are taken as an example in the figure). Each red lamp bead group 311 includes a plurality of red lamp beads 3111 (5 red lamp beads 3111 are taken as an example in the figure), and the plurality of red lamp beads 3111 in the same red lamp bead group 311 are connected in parallel; the green lamp unit 320 includes a plurality of series-connected green lamp bead groups 321 (4 green lamp bead groups 321 are taken as an example in the figure). Each green lamp bead group 321 includes a plurality of green lamp beads 3211 (5 green lamp beads 3211 are taken as an example in the figure), and the plurality of green lamp beads 3211 in the same green lamp bead group 321 are connected in parallel; the blue lamp unit 330 includes a plurality of series-connected blue lamp bead groups 331 (4 blue lamp bead groups 331 are taken as an example in the figure). Each blue lamp bead group 331 includes a plurality of blue lamp beads 3311 (5 blue lamp beads 3311 are taken as an example in the figure), and the plurality of blue lamp beads 3311 in the same blue lamp bead group 331 are connected in parallel. Preferably, as shown in Figure 3 (b), the red lamp unit 310, the green lamp unit 320, and the blue lamp unit 330 are arranged in a staggered manner, and each adjacent red lamp bead 3111, a green lamp bead 3211, and a blue lamp bead 3311 are encapsulated together to form a three-color LED (Light-Emitting diode). When the structures of the red lamp unit 310, the green lamp unit 320, and the blue lamp unit 330 are all as shown in Figure 3 (a), the first endoscope lamp module 300 includes 20 three-color LEDs as shown in Figure 3 (b). In addition, it should be noted that taking the red lamp unit 310 as an example, the number of the red lamp bead groups 311 and the number of the red lamp beads 3111 in a single red lamp bead group 311 are both designed according to actual requirements. The same is true for the green lamp unit 320 and the blue lamp unit 330. The present application does not make a unique limitation on this.

[0019] As one of the embodiments, please refer to Figure 2, the first driving module 200 includes a red light driving unit 210, a green light driving unit 220, and a blue light driving unit 230. In actual applications, the red light driving unit 210 can output a red light driving current to drive the red light unit 310 to emit red visible light, the green light driving unit 220 can output a green light driving current to drive the green light unit 320 to emit green visible light, and the blue light driving unit 230 can output a blue light driving current to drive the blue light unit 330 to emit blue visible light. Based on this, the single-chip microcomputer 100 can control the first driving module 200 to adjust the ratio among the red light driving current, the green light driving current, and the blue light driving current, so as to change the mixing ratio among the red visible light, the green visible light, and the blue visible light, and further change the color of the target visible light emitted by the first cavity mirror lamp module 300. It can be understood that, taking the red light driving current as an example, when the ratio corresponding to only the red light driving current is 0, it means that only the red light unit 310 does not work, that is, only the red light unit 310 does not emit red visible light, while the green light unit 320 emits green visible light and the blue light unit 330 also emits blue visible light. At this time, the target visible light emitted by the first cavity mirror lamp module 300 is the mixture of the green visible light and the blue visible light. In addition, the situations where only the ratio corresponding to the green light driving current is 0, only the ratio corresponding to the blue light driving current is 0, and the ratios corresponding to any two of the red light driving current, the green light driving current, and the blue light driving current are 0 can all be analogized to the description here, and the present application will not elaborate on this. Of course, the single-chip microcomputer 100 can also control the first driving module 200 to keep the ratio among the red light driving current, the green light driving current, and the blue light driving current unchanged, that is, keep the mixing ratio among the red visible light, the green visible light, and the blue visible light unchanged, and increase or decrease the driving current (that is, increase or decrease the red light driving current, the green light driving current, and the blue light driving current simultaneously, and the increase or decrease amplitude of the three is the same), so as to adjust the brightness of the target visible light without changing the color of the target visible light. In one example, the circuit structure of the first driving module 200 is as Figure 4 shown. U5 is a driving chip. A total of 4 patch positions are set on U5. Among them, 3 patch positions are respectively used to set the red light driving unit 210, the green light driving unit 220, and the blue light driving unit 230, and the other patch position is idle. The switch nodes for driving current output in the red light driving unit 210, the green light driving unit 220, and the blue light driving unit 230 are LED_SW01, LED_SW02, and LED_SW03 respectively. In addition, LED_PWM_01~LED_PWM_03 are all input pins of the target enable signal to be given below, and LED_VADJ_01~LED_VADJ_03 are all input pins of the analog dimming signal to be given below.

[0020] As one of the embodiments, please refer toFigure 1 and / or Figure 2 In addition to the structures listed above, the endoscopic surgical lamp further includes a level converter 400 and a digital-to-analog converter 500. The single-chip microcomputer 100 is electrically connected to the level converter 400 and the digital-to-analog converter 500, and the level converter 400 and the digital-to-analog converter 500 are respectively electrically connected to the first driving module 200. In actual applications, the level converter 400 can receive the initial enable signal from the single-chip microcomputer 100, perform level conversion on the initial enable signal to obtain the corresponding target enable signal, and transmit the target enable signal to the first driving module 200. At the same time, the level converter 400 also plays a role in isolating the first driving module 200 from the single-chip microcomputer 100 and strengthening the analog dimming signal below; the digital-to-analog converter 500 can receive the digital dimming signal from the single-chip microcomputer 100, perform digital-to-analog conversion on the digital dimming signal to obtain the corresponding analog dimming signal, and transmit the analog dimming signal to the first driving module 200; the first driving module 200 can respond to the target enable signal to transmit a driving current to the first endoscopic lamp module 300, so that the first endoscopic lamp module 300 emits the target visible light under the drive of the driving current; the first driving module 200 can also adjust the driving current according to the analog dimming signal, thereby changing the color and / or brightness of the target visible light emitted by the first endoscopic lamp module 300. In one example, the initial enable signal is a level signal of 3.3V, and the target enable signal is a level signal of 5.0V. Here, the level signal is preferably a PWM (Pulse Width Modulation) signal.

[0021] Furthermore, the endoscopic surgical lamp further includes a reference voltage source 600 and a human-machine interaction interface 700. The reference voltage source 600 is electrically connected to the digital-to-analog converter 500, and the human-machine interaction interface 700 communicates with the single-chip microcomputer 100. In actual applications, the reference voltage source 600 can provide a reference voltage to the digital-to-analog converter 500 as a reference for the digital-to-analog converter 500 to perform digital-to-analog conversion; the human-machine interaction interface 700 can transmit the dimming information input by the user to the single-chip microcomputer 100 to guide the single-chip microcomputer 100 to generate a digital dimming signal through the dimming information. In one example, the digital-to-analog conversion part of the present application is as Figure 5 shown. U1 is the reference voltage source 600 of the present application, U2 is a digital-to-analog conversion chip (i.e., the digital-to-analog converter 500). U1 outputs a reference voltage of 2.5V through its pin 5, and after being divided by two resistors R1 and R2, it is provided to U2 as a reference for U2 to perform digital-to-analog conversion.

[0022] As one of the embodiments, please refer to Figure 1 and / or Figure 2, in addition to the structures listed above, the laparoscopic operating lamp further includes a second driving module 800 and a second laparoscopic lamp module 900. The single-chip microcomputer 100 is electrically connected to the second driving module 800 through the digital-to-analog converter 500 of the previous embodiment. The second driving module 800 is electrically connected to the second laparoscopic lamp module 900. A level converter 400 of the previous embodiment is also electrically connected between the second driving module 800 and the single-chip microcomputer 100. In actual applications, relying solely on the first driving module 200 to drive the first laparoscopic lamp module 300 to emit the target visible light may not meet the needs of surgeons to perform operations. Therefore, in this embodiment, a second driving module 800 and a second laparoscopic lamp module 900 that play a major lighting role are additionally provided. The single-chip microcomputer 100 can control the second driving module 800 to drive the second laparoscopic lamp module 900, so that the second laparoscopic lamp module 900 emits white visible light. As for the control of the second driving module 800 by the single-chip microcomputer 100, reference can be made to the control of the first driving module 200 by the single-chip microcomputer 100 through the digital-to-analog converter 500 and the level converter 400 in the previous embodiment, and this embodiment will not elaborate on this. It should be noted that similar to the first laparoscopic lamp module 300, the second laparoscopic lamp module 900 can be composed of several LED lamp beads. As for the number of LED lamp beads included in a single second laparoscopic lamp module 900 and their connection forms, they are all designed according to actual needs, and this embodiment does not make a unique limitation on this.

[0023] Further, in order to enable the laparoscopic operating lamp to have excellent lighting effects, both the combination of the first driving module 200 and the first laparoscopic lamp module 300, and the combination of the second driving module 800 and the second laparoscopic lamp module 900 can be set to several independent groups. The single-chip microcomputer 100 controls each group independently. That is to say, both the first laparoscopic lamp module 300 and the first driving module 200 can include several independent ones, and one first driving module 200 corresponds to driving one first laparoscopic lamp module 300; both the second laparoscopic lamp module 900 and the second driving module 800 can include several independent ones, and one second driving module 800 corresponds to driving one second laparoscopic lamp module 900. Preferably, the combination of the first driving module 200 and the first laparoscopic lamp module 300 includes 3 independent groups, while the combination of the second driving module 800 and the second laparoscopic lamp module 900 includes 4 independent groups. In an example, the circuit structure of the second driving module 800 is as Figure 6 shown. Similar to the first driving module 200, U6 is a driving chip. There are 4 patch positions on U6, and each patch position is used to set a second driving module 800. The switching nodes of the driving current output in the 4 second driving modules 800 are LED_SW04, LED_SW05, LED_SW06, and LED_SW07 respectively.

[0024] The above embodiments are only the preferred implementations of the present application, and they are not the only limitations on the content related to the laparoscopic surgical lamp. In this regard, those skilled in the art can make flexible settings based on the above embodiments according to the actual application scenarios. In addition, it can be understood that through the implementation of the above embodiments of the present application, the single-chip microcomputer 100 is used to control the first driving module 200, so that the first driving module 200 transmits a driving current to the first laparoscopic lamp module 300, so as to drive the first laparoscopic lamp module 300 to emit the target visible light through the driving current, and the single-chip microcomputer 100 can also be used to control the first driving module 200 to adjust the driving current, so as to change the color and / or brightness of the target visible light. Then, when the laparoscopic surgical lamp of the present application is applied to laparoscopic surgery, the surgeon can issue an instruction to the single-chip microcomputer 100, and then the single-chip microcomputer 100 can control the first driving module 200 to adjust the driving current according to the received instruction, so as to change the color and / or brightness of the target visible light emitted by the first laparoscopic lamp module 300. That is to say, the laparoscopic surgical lamp of the present application can perform arbitrary adjustment of color and brightness, not only compensating the color rendering index of the laparoscopic surgical lamp, but also providing lights of multiple colors and multiple brightness levels for the surgeon to choose from, meeting the usual eye habits of the surgeon while avoiding the visual fatigue caused by the surgeon performing surgery under a single-color light for a long time.
