Please refer to fig. 1. An endoscope light source system according to the present embodiment includes: the device comprises a laser light source 11, a first collimating lens 13, an LED light source 14, a second collimating lens 15, a dichroic mirror 17, a focusing lens 19 and a fiber tube 20; the laser light source 11 and the LED light source 14 output a first parallel light beam and a second parallel light beam after being collimated by the first collimating lens 13 and the second collimating lens 15, respectively, and both the first parallel light beam and the second parallel light beam are incident on the dichroic mirror 17, and are vertically incident on the focusing lens 19 after being reflected and transmitted by the dichroic mirror 17, respectively; and the combined beam is focused at the focal point of the focusing lens 19 and enters the fiber tube 20; the optical fiber tube 20 is used for connecting with external equipment.
In use, the optical fiber tube 20 is connected to an external device (e.g. a laparoscope), and the laser light source 11 and the LED light source 14 are turned on simultaneously, so that the laser light source 11 and the LED light source 14 can be focused at the focus of the focusing lens 19 and enter the optical fiber tube 20; and the light in the optical fiber tube 20 can be irradiated on the patient by operating the external device, so as to diagnose and treat the patient.
As can be seen from the above solutions, in the endoscope light source system according to the embodiment of the present application, the laser light source 11, the first collimating lens 13, the LED light source 14, the second collimating lens 15, the dichroic mirror 17, the focusing lens 19, and the optical fiber tube 20 are arranged such that the laser light source 11 and the LED light source 14 are first collimated and shaped by the first collimating lens 13 and the second collimating lens 15, respectively, to output the first parallel light beam and the second parallel light beam; then the first parallel light beam and the second parallel light beam are respectively reflected and transmitted by the dichroic mirror 17 and then vertically incident on the focusing lens 19; the combined beam is focused at the focal point of the focusing lens 19 and enters the fiber tube 20; therefore, the laser light source 11 and the LED light source 14 can be focused and shaped; therefore, the light energy utilization rate of the LED light source 14 and the laser light source 11 is improved by shaping the laser light source 11 and the LED light source 14, so that the LED light source 14 has the characteristics of high luminous flux, high color rendering, high color temperature and good uniformity, and the laser light source 11 has the characteristics of high precision, high stability and good uniformity.
As shown in fig. 1, in the present embodiment, the laser light source 11 and the LED light source 14 output the first parallel light beam and the second parallel light beam after being collimated by the first collimating lens 13 and the second collimating lens 15, respectively. That is, the laser light source 11 outputs a first parallel beam after being collimated by the first collimating lens 13. The LED light source 14 outputs a second parallel light beam after being collimated by the second collimating lens 15. For example, as shown in fig. 1, light emitted from the laser light source 11 is irradiated onto the first collimating lens 13 in a downward direction, and is collimated by the first collimating lens 13 to output a first parallel beam in the downward direction. The light emitted by the LED light source 14 travels right and irradiates the second collimating lens 15, and is collimated by the second collimating lens 15 to output a second parallel light beam traveling right. In this way, the laser light source 11 and the LED light source 14 can be collimated and shaped by the first collimating lens 13 and the second collimating lens 15, respectively. Further, the first parallel light beam and the second parallel light beam are both incident on the dichroic mirror 17, and are vertically incident on the focusing lens 19 after being reflected and transmitted by the dichroic mirror 17 respectively; and the combined beam is focused at the focal point of the focusing lens 19 and enters the fiber tube 20. For example, as shown in fig. 1, the first parallel light beam propagates downward and is incident on the right surface of the dichroic mirror 17, and propagates rightward by being reflected by the right surface of the dichroic mirror 17 and is perpendicularly incident on the focusing lens 19, is converged at the focal point of the image plane of the focusing lens 19 by the focusing lens 19, and enters the fiber tube 20. The second parallel light beam propagates rightward to be incident on the left surface of the dichroic mirror 17, and is transmitted from the left surface of the dichroic mirror 17 to the right surface of the dichroic mirror 17; and propagates rightward with normal incidence on the focusing lens 19, converges at the focal point of the image plane of the focusing lens 19 via the focusing lens 19, and enters the fiber tube 20. The laser light source 11 and the LED light source 14 can be focused and shaped by the focusing lens 19. Therefore, the light energy utilization rate of the LED light source 14 and the laser light source 11 is improved by shaping the laser light source 11 and the LED light source 14, so that the LED light source 14 has the characteristics of high luminous flux, high color rendering, high color temperature and good uniformity, and the laser light source 11 has the characteristics of high precision, high stability and good uniformity.
Further, the laser source 11 may be a fluorescence excitation light source emitted by a semiconductor laser. Of course, the laser light source 11 is not limited to one emitted by a semiconductor laser, and may be one emitted by another laser, and the present application is not limited thereto. Further, the output power of the semiconductor laser is 1W. The central wavelength of the fluorescence excitation light source is 785 nm.
Further, the laser light source 11 is located upstream of the first collimating lens 13 in the light traveling direction, so that the light emitted from the laser light source 11 can be collimated and shaped by the first collimating lens 13. For example, as shown in fig. 1, the laser light source 11 is located above the first collimating lens 13. For example, as shown in fig. 1, the optical axis of the laser light source 11 and the optical axis of the first collimating lens 13 extend in the vertical direction. Further, the optical axis of the laser light source 11 coincides with the optical axis of the first collimating lens 13.
In one embodiment, the first collimating lens 13 includes a first convex lens 21 and a second convex lens 22 that are coaxially disposed. For example, as shown in fig. 1, the first convex lens 21 and the second convex lens 22 are arranged in parallel in the vertical direction. Further, the distance between the first convex lens 21 and the second convex lens 22 is 23.5 nm; the focal lengths of the first convex lens 21 and the second convex lens 22 are 175 nm and 49 nm, respectively.
In one embodiment, the second collimating lens 15 includes a third convex lens 23 and a fourth convex lens 24 that are coaxially disposed. For example, as shown in fig. 1, the third convex lens 23 and the fourth convex lens 24 are juxtaposed in the left-right direction. The distance between the third convex lens 23 and the fourth convex lens 24 is 5 nm; the third convex lens 23 and the fourth convex lens 24 have respective focal lengths of 39 nm and 30 nm, respectively.
In one embodiment, the focusing lens 19 includes a fifth convex lens 25, a sixth convex lens 26, and a seventh convex lens 28, which are coaxially arranged in this order. For example, as shown in fig. 1, the fifth convex lens 25, the sixth convex lens 26, and the seventh convex lens 28 are arranged in this order in the left-right direction. The distance between the fifth convex lens 25 and the sixth convex lens 26 is 8 nm; the distance between the sixth convex lens 26 and the seventh convex lens 28 is 2 nm; the focal lengths of the fifth convex lens 25, the sixth convex lens 26, and the seventh convex lens 28 are 49 nm, 40 nm, and 32 nm, respectively.
Further, the LED light source 14 emits light having a wavelength of 400 nm to 700 nm.
In one embodiment, the focusing lens 19 is disposed coaxially with the second collimating lens 15. For example, as shown in fig. 1, the optical axes of the third lens, the fourth lens, the fifth lens, and the sixth lens are collinear and extend in the left-right direction. The dichroic mirror 17 is located between the second collimating lens 15 and the focusing lens 19. So that the second parallel light beam output after the collimation and shaping by the second collimating lens 15 can be vertically irradiated on the focusing lens 19 through the dichroic mirror 17. Further, the first collimating lens 13 is located on a side of the dichroic mirror 17 facing away from the second collimating lens 15. For example, as shown in fig. 1, the first collimating lens 13 is located on the right side of the dichroic mirror 17. The second collimating lens 15 is located to the left of the dichroic mirror 17. So that the dichroic mirror 17 can reflect and transmit the collimated and shaped first and second parallel light beams by the first and second collimating lenses 13 and 15, respectively.
Further, the optical axis of the first collimating lens 13 is perpendicular to the optical axis of the second collimating lens 15. So that the first parallel light beam and the second parallel light beam after being collimated and shaped by the first collimating lens 13 and the second collimating lens 15 are perpendicular. The optical axis of the collimator lens 13 makes an angle of 45 ° with the normal to the dichroic mirror 17. The optical path of the first parallel light beam reflected by the dichroic mirror 17 coincides with the optical axis of the second collimator lens 15. Specifically, according to snell's law, the dichroic mirror 17 changes the focal lengths of the first collimating lens 13 and the second collimating lens 15, and the light emitted from the dichroic mirror 17 has the same slope as the light entering, and according to the paraxial ray tracing formula, the 45 dichroic mirror 17 generates a longitudinal displacement of 0.5mm, so that the displacement compensation of 0.5mm is performed after the transmission light path passes through the dichroic mirror 17 and the displacement compensation of 0.5mm is performed after the reflection light path passes through the dichroic mirror 17. In this way, the reflected light energy of the first parallel light beam reflected by the dichroic mirror 17 and the transmitted light energy of the second parallel light beam transmitted by the dichroic mirror 17 can be combined.
Further, the optical fiber tube 20 is used for connection with an external device. In particular, the external device may be a laparoscope, for example. So that the focused combined beam of light can be irradiated on the affected part of the patient through the optical fiber tube 20 for diagnosis and treatment through the optical fiber tube 20.
In one embodiment, the endoscope light source system according to the embodiment of the present application further includes: a housing 33 having a sealed chamber 35. As shown in fig. 1, for example, the housing 33 is hollow as a whole. The hollow portion forms the sealed chamber 35. Further, the housing 33 is provided with a first opening 27, a second opening 29, and a third opening 31 communicating with the sealed chamber 35. The laser light source 11 is arranged in the first opening 27 in a penetrating way; the LED light source 14 is arranged in the second opening 29 in a penetrating way; the optical fiber tube 20 is inserted into the third opening 31. For example, as shown in fig. 1, the first opening 27 is provided on the upper side of the housing 33. The second opening 29 is disposed on the left side of the housing 33. The third opening 31 is provided on the right side of the housing 33. Further, a connecting pipe 37 is hermetically connected to the wall of the first opening 27. The connection pipe 37 extends in a direction perpendicular to the direction in which the housing 33 extends. The laser light source 11 and the first collimating lens 13 are arranged in sequence from outside to inside in the extending direction of the connecting pipe 37, so that the space occupied by the sealed chamber 35 is reduced; on the other hand, the laser light source 11 and the first collimating lens 13 can be fixed through the hole wall of the first opening 27, so that the laser light source 11 and the first collimating lens 13 are prevented from shaking, and the stability of a light path is further influenced. Further, for example, as shown in fig. 1, the LED light source 14 and the second collimating lens 15 are arranged in sequence from outside to inside in the extending direction of the second opening 29, so that the space occupied by the sealed chamber 35 is reduced; on the other hand, the LED light source 14 and the second collimating lens 15 can be fixed through the hole wall of the second opening 29, so that the LED light source 14 and the second collimating lens 15 are prevented from shaking, and the stability of the light path is further affected. Further, as shown in fig. 1, for example, the dichroic mirror 17 and the focusing lens 19 are located in the sealed chamber 35. So that the light emitted by the laser light source 11 and the LED light source 14 can be protected by the sealed chamber 35 to avoid injury to the operator.
