[0017] As Figure 1The utility model discloses an endoscope, including endoscope tip, the endoscope tip includes the end head body 1 and is located on the first accommodating cavity 2, second accommodating cavity 3 and third accommodating cavity 4 of end head body 1, and the first accommodating cavity 2 and second accommodating cavity 3 are located in the lateral array distribution of third accommodating cavity 4, is equipped with image acquisition module 5 in third accommodating cavity 4, is equipped with first light source device 20 in first accommodating cavity 2, is equipped with second light source device 30 in second accommodating cavity 3, is equipped with first light -transmitting part 21 in the front end of first light source device 20, is equipped with light -transmitting part 31 in the front end of second light source device 30, and the light -transmitting part is used to gather and emit the light of light source device.
[0018] The light -transmitting part in the endoscope can make the outgoing light more concentrated, thereby increasing the brightness of the outgoing light, and accordingly reducing the influence of the outgoing light on the imaging of the image acquisition module 5.
[0019] Optionally, in an embodiment of the present application, the first accommodating cavity 2, the second accommodating cavity 3, the third accommodating cavity 4 and the end head body 1 are integrally injection molded using a COC (cyclic olefin copolymer) material, and the convex side of the first light -transmitting part 21 and the second light -transmitting part 31 is located on the outside of the end head body 1. Integrally injection molding reduces the processing procedure, thereby improving the production efficiency, and also increases the sealing property of the entire assembly.
[0020] The COC material has the following advantages:
[0021] High transparency: light transmittance up to 91%, suitable for optical elements;
[0022] High heat resistance: glass transition temperature reaches 140~170℃, suitable for high temperature environment;
[0023] Low hygroscopicity: small saturated water absorption rate, good dimensional stability;
[0024] Low birefringence: excellent optical performance, suitable for precision optical elements;
[0025] Good biocompatibility: very suitable for medical and food.
[0026] Therefore, the COC material is preferably used as the integrally injection molding material.
[0027] Optionally, in an embodiment of the present application, the accommodating cavities arranged on the lateral side of the third accommodating cavity 4 can be 2, 3, 4 or the like, which are not limited herein, and these accommodating cavities are provided with the light source device and the light -transmitting part like the first accommodating cavity 2 and the second accommodating cavity 3. Each more accommodating cavity increases one irradiation light source, thereby increasing the light brightness of the endoscope.

[0029] Preferably, the plane side of the first light-transmitting piece 21 and the second light-transmitting piece 31 is a regular circle, and a predetermined length of the plane side extends outward in the circumferential direction, and the extended part is used for adhering the light-transmitting piece; the plane side adopts a regular circle, which corresponds to the shape of the first light-transmitting piece 21 and the second light-transmitting piece 31, and the design and manufacture of the mold are simpler and more convenient, thereby improving the production efficiency.
[0030] Optionally, in an embodiment of the present application, the first light-transmitting piece 21 and the second light-transmitting piece 31 converge and emit the light emitted by the light source devices 20 and 30, and the emission angle of the light is 100-110 degrees; if the emission angle of the light is too large, the light is not sufficiently converged, and the effect of increasing the brightness of the emitted light cannot be achieved; if the emission angle of the light is too small, the irradiation area of the light is too small, which reduces the irradiation range of the emitted light and makes the observation range too small; therefore, the emission angle of the light is selected to be 100-110 degrees.
[0031] Optionally, in an embodiment of the present application, the first light source device 20 and the second light source device 30 adopt LED lamps, which are used for providing illumination light sources. The LED lamps have the advantages of high efficiency, long service life, environmental protection, fast response and controllability.

[0033] Optionally, in some embodiments of the present application, the shape of the plane side of the first light-transmitting piece 21 and the second light-transmitting piece 31 can be any shape that can adhere the first light-transmitting piece 21 and the second light-transmitting piece 31, such as a regular circle, an ellipse, a square and the like.
[0034] As described above, the light emitted by the first light source device 20 and the second light source device 20 in the first accommodating cavity 2 and the second accommodating cavity 3 of the end body of the endoscope is converged and emitted by the first light-transmitting piece 21 and the second light-transmitting piece 31, so that the emitted light is more concentrated, thereby increasing the brightness of the emitted light, and correspondingly reducing the influence of the emitted light on the imaging of the image acquisition module.
[0035] The various embodiments in the specification are described in a related manner, and the same or similar parts between the various embodiments can be mutually referred to, and each embodiment focuses on the difference from other embodiments.
[0036] The above merely describes the specific embodiments of the present application, and the protection scope of the present application is not limited thereto.
