Oral surgery mainly provides surgical scope illumination by doctors wearing headlamps, but there are still clinical restrictions on use. The limitations are (1) due to the angle of the head swing and the shadow of the visual field during the operation and (2) due to projection of the light source being worn on the doctor’s head and the length of the wire, and the fiber-optic wire will affect the relative position of the surgical instrument and limit the scope of the doctor’s activity. This study will focus on the development of oral lighting optical microstructure devices to solve and improve the abovementioned clinical use limitations. The production method is to make an oral lighting mold by 3D printing technology and use the polydimethylsiloxane (PDMS) of liquid silicone material to make an oral lighting device with mold casting technology. The results show that the optical simulation achieves the target light distribution by optimizing the three geometric reflection surfaces combined with the lens design by the optimization method, and the maximum illumination value can reach 5102 lux. According to the measurement results of mold casting technology, the average errors of the profile of the 3D printing finished product and the PDMS finished product of the oral device structure are about 1.4% and 16.9%, respectively. Because the contour of the PDMS finished product’s error caused the light to shift by 0.5∼3 mm distance, the light is still concentrated in the range of the tonsils, so this study can be defined as within the acceptable range of within 16.9% of the intra lighting error. The development of oral lighting devices in this study will reduce the burden on physicians in nonprofessional fields, reduce the time of surgery for patients to maintain the health of doctors, and rise the level of medical equipment to increase surgical safety.

用于口腔的光学设备的最佳照明

口腔外科手术主要由戴大灯的医生提供手术范围照明，但仍然存在临床使用限制。局限性在于（1）由于操作过程中头部摆动的角度和视野的阴影，以及（2）由于光源在医生头上的投影以及导线的长度以及光纤线会影响手术器械的相对位置并限制医生的活动范围。这项研究将集中在口腔照明光学微结构装置的开发上，以解决和改善上述临床使用限制。生产方法是通过3D打印技术制造口腔照明模具，并使用液态有机硅材料的聚二甲基硅氧烷（PDMS）通过铸模技术制造口腔照明装置。结果表明，光学仿真是通过优化三个几何反射面，再结合优化设计的透镜设计，实现了目标光分布，最大照度可以达到5102 lux。根据铸模技术的测量结果，口腔器械结构的3D打印成品和PDMS成品轮廓的平均误差分别约为1.4％和16.9％。由于PDMS成品的轮廓误差导致光线偏移了0.5〜3 mm的距离，光线仍然集中在扁桃体的范围内，因此本研究可以定义为在16.9％的可接受范围内。内部照明错误。
