Description

Technical Field

[0001] The utility model belongs to the technical field related to medical equipment, and in particular relates to a guide rail ceiling type operating lamp. Background Art

[0002] A surgical light is a special lighting device used in operating rooms. It is usually used to provide bright, even light so that doctors and medical staff can clearly see the patient's body parts during surgery. Surgical lights usually have adjustable light brightness and color temperature to accommodate different types of surgeries and medical procedures. Some surgical lights are also equipped with shadowless technology to reduce shadows and reflections in surgical scenes and provide a clearer field of vision. Surgical lights usually use LED or fluorescent lamps as light sources, which have a long service life and low energy consumption. The lighting working distance of surgical lights is generally about 1m, and the illumination values ​​at different distances are different. Doctors may need to move the position of the surgical light at any time during the operation.

[0003] However, since there is no way to ensure that the lighting distance after the move is the same as before, the illumination value of the operating area will also change, which will have an adverse effect on the doctor's surgical results. Traditional surgical lights can only reduce the adverse effects caused by this by increasing the lighting depth, but cannot fundamentally maintain the constant illumination value of the operating area. Utility Model Content

[0007] A center handle is arranged inside the handle shell, and a distance measuring component is arranged inside the center handle. The distance measuring component consists of a laser transmitter, a laser receiver and an information transmission line. The laser transmitter is provided with a transmission line, and a pressure sensing component is arranged at the end of the transmission line. The laser receiver is provided with an information transmission line, and an illumination feedback component is arranged at the end of the information transmission line.

[0013] Preferably, the longitudinally rotating ring arm is fixedly connected to the lamp shaft, and the longitudinally rotating ring arm is movably connected to the operation screen, and the longitudinally rotating ring arm can drive the lamp head of the surgical lamp to rotate longitudinally.

[0014] Compared with the prior art, the utility model provides a guide rail ceiling type surgical lamp, which has the following beneficial effects:

[0015] 1. Through the setting of the distance measuring component, the distance measuring component adopts a laser distance measuring system, which includes a laser transmitter, a laser receiver and an information transmission line. When the laser distance measuring system is used, the laser transmitter emits a laser and the laser receiver starts counting at the same time. When the laser beam encounters the obstruction of the patient's surgical site, it is scattered and part of the scattered light is received by the laser receiver. At this time, the laser receiver stops counting and calculates the distance of the obstruction. The effective distance measuring range of the laser distance measuring system is set to 0.5m~2m, so that the interference signal generated by other obstructions can be avoided as much as possible. Through the setting of the illumination feedback component, the laser receiver sends the distance information to the illumination feedback component through the information transmission line. The illumination feedback component compiles the lamp head brightness correction coefficient table corresponding to different distances through software. The correction coefficient corresponding to the distance is found by comparison and the brightness of the light source is corrected. The illumination value of the surgical area after correction is consistent with the previous one. The surgical lamp uses the distance measuring component to feed back the distance information to the surgical lamp, and the correction coefficient corresponding to the distance is found through the illumination feedback component and the brightness of the light source is automatically adjusted accordingly, so that the illumination value of the surgical area remains unchanged.

[0016] 2. Through the setting of the pressure sensing component, when there is no pressure on the surface of the handle shell, the capacitive sensor in the pressure sensing component will generate a lower frequency. When the doctor holds the handle shell to move the operating light head, the capacitive sensor in the pressure sensing component senses the change in pressure and generates a higher frequency. The high-frequency signal can pass through the high-frequency filter and generate an activation signal. The activation signal then activates the laser transmitter through the transmission line to start the laser ranging component. When the pressure is eliminated, the activation signal disappears and the entire laser ranging system stops working. The operating light uses the pressure sensing method of the pressure sensing component to activate the ranging component, so that the entire system only works when the operating light head moves, avoiding adverse effects on the operation during the operation when the operating light head is stationary.

[0027] Preferably, through the setting of the distance measuring component 4, the distance measuring component 4 adopts a laser distance measuring system, which includes a laser transmitter 8, a laser receiver 9 and an information transmission line 10. When the laser distance measuring system is used, the laser transmitter 8 emits a laser, and the laser receiver 9 starts counting at the same time. When the laser beam encounters the obstruction of the patient's surgical site, it is scattered, and part of the scattered light is received by the laser receiver 9.
