Also, the main body 110 may include a light transmission region 110A through which light irradiated from the first light source 122A is transmitted at least in part, and for example, the first light source section 1100A includes the light transmission region 110A in at least part of the main body 110 to enlarge an area to which light irradiated from the first light source 122A reaches, so that the inside of a human organ can be easily observed by a camera section 400 described later, or a sterilization area can be increased.
Referring to fig. 3, the first light source 1100B may further include a collimator lens 130 in addition to the first light source 1100A described above with reference to fig. 2. The parallel light lens 130 may be incident light from the light emitting diode 172 irradiating light in a form diffused in a radiation direction from the center, and may convert it to constitute parallel light. At this time, when the parallel light lens 130 is arranged between the first light source 122A and the end of the main body 110, the first light source section 1100B may be made not to include the aforementioned light transmission region 110a, or a region from the position where the parallel light lens 130 is arranged to the end of the main body 110 may be constituted as the light transmission region 110 a.

That is, the first light source unit 100A can further promote the sterilization effect and the hemostatic effect on the bleeding part by the ultraviolet rays irradiated from the first light source 122A by controlling the arrangement order of the first light source 122A, the collimator lens 130, and the narrow-angle lens 140 to improve the efficiency of reaching the light condensed at the focal point F. In addition, a reflection plate (not shown in the drawing) is provided on an inner wall of the body 110, for example, an inner wall provided between the parallel light lens 130 and the narrow angle lens 140, so that the light condensing efficiency can be further improved.
Referring to fig. 6, the body 110 includes a light source setting part 111 and a focus adjustment part 112 in the first light source part 100B, and since movement of the focus adjustment part 112 can be achieved, a focal length can be adjusted. For example, the light source setting part 111 may be arranged with the first light source 122A and the parallel light lens 130, and the focus adjusting part 112 may be arranged with the narrow angle lens 140, and the focus adjusting part 112 may be in a form capable of being moved by the distance adjusting part 150. For example, the distance adjusting unit 150 may be configured as follows: the telescopic movement can be achieved and the forward and backward movement can be performed by the screw-type rotation, and the distance between the parallel light lens 130 and the narrow angle lens 140 increases when rotating in one direction and shortens when rotating in the opposite direction. At this time, the narrow angle lens 140 is disposed at a position spaced apart from the end of the long distance adjusting part 150 by a predetermined distance when the distance between the light source setting part 111 and the focus adjusting part 112 becomes the shortest distance, so that the narrow angle lens 140 may not be damaged by the movement of the distance adjusting part 150, or a separate stopper 151 may also be provided behind the narrow angle lens 140. That is, the focal length of the endoscope apparatus is adjusted by the movement of the focus adjusting part 112 in which the narrow-angle lens 140 is disposed according to the use environment of the endoscope apparatus, so that the sterilization efficiency and the hemostatic effect can be further improved.
Referring to fig. 7, the first light source part 100C may include a plurality of light emitting diodes 172 irradiating light of at least two different wavelengths.

The form of the substrate 121C is not particularly limited as long as the internal space of the first light source unit 100C can be effectively used, but a plate form inclined at a predetermined angle may be applied in order to reduce the thickness of the tube 1 at a level where the assembling of the plurality of light emitting diodes 172 is possible and the pain of the patient can be alleviated, or a flexible form, a conical form, a polyhedral form 121D (fig. 8), or a cylindrical form 121E (fig. 9) may be applied in order to increase the number of light emitting diodes 172 to be assembled. In this case, in order to improve the light condensing efficiency of the light irradiated from the light emitting diode 172 mounted on the substrate in a plate form, a flexible form, a cone form, a polyhedron form, or a cylinder form inclined at a predetermined angle, the main body 110 may be provided with a reflection plate 160 on an inner wall thereof. Further, the distance adjusting part 150 described above with reference to fig. 3 is further provided, so that the focal distance can be adjusted according to the use environment. That is, the first light source unit 121C is configured such that a plurality of light emitting diodes 172 are mounted on a substrate having a plate shape, a flexible shape, a conical shape, a polyhedral shape 121D (fig. 8), or a cylindrical shape 121E (fig. 9) inclined at a predetermined angle, thereby reducing the thickness and alleviating pain of a patient, and the light collection efficiency can be improved by allowing light to pass through the collimator lens 130 and the narrow-angle lens 140 in order while maintaining the light irradiation efficiency by the reflector 160 disposed on the inner wall of the body 110. Therefore, the endoscope apparatus is provided with the plurality of light emitting diodes 172 irradiating light of at least two different wavelengths, so that the driving of the light emitting diodes 172 can be controlled according to the purpose of use, such as observation, sterilization, hemostasis, or the like, or the amount of light irradiation can be controlled by controlling the number of the light emitting diodes 172 to be driven, thereby not only improving the observation effect by the camera unit 400 but also further improving the sterilization and hemostasis effects.
