Description

Technical Field

[0001] The utility model relates to a light effect improving device for a rigid endoscope, in particular to a light effect improving device for a rigid endoscope with a viewing angle of 30 degrees. Background Art

[0002] The rigid optical endoscope is mainly composed of an imaging system and a lighting system. The imaging system is composed of a slender outer tube, which contains an optical system composed of many lenses. The lighting system is mainly composed of three parts: a light source, a fiber optic transmission system, and a lighting port. The light source generates high-brightness, high-uniformity light, which is transmitted to the lighting port through the fiber optic transmission system. The lighting port then evenly irradiates the light onto the surface of the object being inspected. In this way, the operator can capture clear images through the endoscope's camera for subsequent analysis and diagnosis.

[0003] At present, the lighting system of rigid optical endoscopes consists of 4 channels, such as Figure 4 As shown, the emission direction is designed to be evenly distributed with the endoscope imaging port. Theoretically, the lighting effect is uniform. However, since the diameter of the fiber bundle is smaller than the fiber port and the fiber has resilience, the actual emission direction of the fiber deviates from the design value, causing the endoscope lighting effect to change and deviate from the design value.

[0017] like Figures 1 to 3 As shown, the rigid endoscope light efficiency enhancement device involved in the present application includes a base plate 1, on which a fixing seat 17 is fixedly connected, for assembling a rigid endoscope A.

The horizontal lower plate 1701 and the vertical plate 1702 are fixedly connected to the bottom plate 1. And the horizontal upper plate 1703 form a U shape, and the three can be an integrated structure. A first opening 1704 is provided at the side end surface of the horizontal lower plate 1701 away from the vertical plate 1702, and correspondingly, a second opening 1705 is provided at the side end surface of the horizontal upper plate 1703 away from the vertical plate 1702, and a T-shaped fixing block 18 that can be fixed by magnetic attraction is provided at the second opening 1705, and the outer tube of the rigid endoscope can be fixed by the cooperation of the second opening 1705 and the T-shaped fixing block 18. When the rigid endoscope A needs to be assembled, the rigid endoscope A is assembled into the fixing seat 17 from one side of the first opening 1704 and the second opening 1705, so that the prism chamber A01 of the rigid endoscope A is located between the horizontal upper plate 1703 and the horizontal lower plate 1701. The outer tube of the rigid endoscope A passes through the second opening 1705 and is magnetically fixed at the second opening 1705 by the T-shaped fixing block 18, thereby fixing the rigid endoscope A.

[0018] A connecting plate 5 is provided above the rigid endoscope A. In the present embodiment, the connecting plate 5 includes a first connecting plate and a second connecting plate connected to each other. The two can be an integrated structure, and the angle between the two is an obtuse angle, which faces the bottom plate 1, and the length of the first connecting plate is less than the length of the second connecting plate.

[0019] One end of the connecting plate 5 (one end of the second connecting plate) is fixedly connected to a guide rail fixing plate 9, on which a guide rail 10 is provided. The guide rail 10 is located below the connecting plate 5, and a slider 11 used in conjunction with the guide rail 10 is fixed on an optical fiber fixing plate 12. Specifically, a plurality of positioning wire holes 19 are provided on the optical fiber fixing plate 12, and the slider 11 is connected to the optical fiber fixing plate 12 by tightening screws. The optical fiber fixing plate 12 has N optical fiber input ports 15 spaced apart on its surface close to the rigid endoscope, and the number of the optical fiber input ports 15 is consistent with the number of the optical fiber illumination ports A02 of the rigid endoscope. The optical fiber fixing plate 12 has N optical fiber output ports 16 correspondingly disposed on its surface away from the rigid endoscope, and each optical fiber input port 15 is correspondingly connected to each optical fiber output port 16, and the diameter of the optical fiber input port 15 is larger than the diameter of the corresponding optical fiber output port 16, and the diameter of the through hole formed by the connected optical fiber input ports 15 and optical fiber output ports 16 gradually decreases.

[0020] A screw hole 13 is provided at the upper end surface of the optical fiber fixing plate 12, and the adjusting screw rod 14 includes a head and a screw rod portion that are connected to each other. The screw rod portion passes through a first through hole provided on the connecting plate 5 and is used in conjunction with the screw hole 13. The head size of the adjusting screw rod 14 is larger than the diameter of the first through hole. The head of the adjusting screw rod 14 and the optical fiber fixing plate 12 are disposed on the upper and lower sides of the connecting plate 5. When the adjusting screw rod 14 is manipulated, the optical fiber fixing plate 12 can slide together with the slider 11 along the guide rail 10 until the optical fiber fixing plate 12 is adjusted to a suitable position.

[0021] The base plate 1 is fixedly connected to the column plate 2 . In order to firmly connect the two, the column plate 2 is connected to the reinforcing rib 3 . The column plate 2 and the reinforcing rib 3 are both connected to the base plate 1 .

[0022] The middle part of the upper end surface of the column plate 2 is recessed downward to form a third opening 4, and a connecting shaft 6 is connected between the two opposite side walls of the third opening 4, and the connecting shaft 6 is connected to the other end of the connecting plate 5, and the connecting plate 5 can rotate relative to the column plate 2. Specifically, the connecting shaft 6 is fixedly connected between the two opposite side walls of the third opening 4, and an axial hole is provided in the connecting plate 5, through which the connecting plate 5 is sleeved on the connecting shaft 6, so that the connecting plate 5 can rotate relative to the column plate 2.

When it is necessary to adjust the angle of the optical fiber fixing plate 12, it is sufficient to adjust the degree of threaded connection between the screw 8 and the adapter plate 7. Due to the gravity of the connecting plate 5, the optical fiber fixing plate 12, the guide rail fixing plate 9, etc., the connecting plate 5 will rotate downward until the nut of the screw 8 abuts against the column plate 2, and the adjustment of the angle of the optical fiber fixing plate 12 is completed.

[0024] During specific use, the rigid endoscope A is assembled at the fixing seat 17, and the optical fiber at the optical fiber illumination port A02 of the rigid endoscope A is passed through the optical fiber inlet 15 and passed through the optical fiber outlet 16. According to actual needs, the adjusting screw 14 is manipulated to enable the optical fiber fixing plate 12 and the slider 11 to slide along the guide rail 10 until the optical fiber fixing plate 12 is adjusted to a suitable position. When it is necessary to adjust the angle of the optical fiber fixing plate 12, the degree of threaded connection between the screw 8 and the adapter plate 7 can be adjusted. The above operation is used to adjust the emission direction of the optical fiber of the rigid endoscope to meet the demand for the optical fiber emission direction.

[0025] During the production process of rigid endoscopes, the optical fiber at the head of the rigid endoscope must first be fixed in direction using the device involved in the present application, and then undergo the production processes of gluing, baking, trimming, and polishing.

[0026] The rigid endoscope light efficiency enhancement device involved in the present application has the characteristics of stable placement, easy use, and obvious improvement effect. It can change the optical fiber emission direction, correct the optical fiber that deviates from the direction, and improve the light efficiency of the endoscope lighting system, thereby making the endoscope lighting system have the characteristics of high brightness, good uniformity, and easy observation.

Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
