Description

TECHNICAL FIELD

[0002] An endoscope system mainly consists of an endoscope lens, a light source system and a camera system, and the imaging quality of the endoscope lens will directly affect the use effect. During the use of the endoscope device, due to the internal and external temperature difference and the humid environment in the use environment, the endoscope lens is prone to fogging, which makes it impossible to clearly observe the specific details of the applicable object, affects the imaging effect of the endoscope, and reduces the success rate of operation.

[0003] The fogging of the endoscope is divided into external fogging and internal fogging. The external fogging refers to the fogging of the protective window.

The optical film has poor adhesion, and after repeated wiping with gauze, medical cotton and the like, it is easy to gradually fall off; the physiological saline heating lens is slow, and the lens needs to be repeatedly pulled out, causing interruption of the operation process.

At the same time, during the use of the endoscope, the viewing window protection glass can be continuously heated under the condition of continuous illumination of the cold light source device, and the anti-fog effect is maintained during use. The operation time is shortened by avoiding the frequent operation of taking out and inserting the endoscope during operation. In addition, the structure of the components sealed in the tip of the endoscope is optimized, so that the anti-fog effect can be maintained for a long time. In addition, the structure does not introduce new components, which can effectively avoid potential risks caused by biocompatibility problems, and has a higher safety factor. Furthermore, the viewing window protection glass is the main device that causes fogging. The heat conduction ring is wrapped around the edge part of the viewing window protection glass. When the viewing window protection glass is connected to the anti-fog heat conduction structure, the heat conduction efficiency between the anti-fog heat conduction structure and the viewing window protection glass can be effectively improved through the heat conduction ring, and the temperature rising time of the viewing window protection glass is shortened, thereby further preventing fogging.

[0034] Please refer to Figure 1 , with reference to Figures 2 to 6The application provides an anti-fog structure for an endoscope, which mainly comprises an outer tube 1, an inner tube 2, a light guide material layer 3, a heat conduction ring 10, a window protection glass 4 and an anti-fog heat conduction structure 5; wherein the anti-fog heat conduction structure 5 is sleeved on the end of the inner tube 2, the anti-fog heat conduction structure 5 comprises an annular heat conduction body 11, a plurality of sector positioning blocks 12 extending in the circumferential direction and a plurality of curved heat conduction connecting layers 13 are arranged on the outer surface of the annular heat conduction body 11, each heat conduction connecting layer 13 is between two adjacent sector positioning blocks 12 and is arranged on the outer surface of the annular heat conduction body 11; an anti-fog heat conduction layer 6 extending in the circumferential direction and in an arc shape is arranged at the edge of the outer surface of the end of the heat conduction connecting layer 13, the anti-fog heat conduction layer 6 is between two adjacent sector positioning blocks 12; a first high-reflection coating 7 is coated on the outer surface of the anti-fog heat conduction layer 6; the light guide material layer 3 is arranged between the inner surface of the outer tube 1 and the outer surface of the heat conduction connecting layer 13 and is arranged on the outer surface of the heat conduction connecting layer 13, is between two adjacent sector positioning blocks 12 and abuts against the side wall of the sector positioning block 12 on the opposite side; meanwhile, a second high-reflection coating 8 is coated on the outer surface of the annular heat conduction body 11, and the light guide material layer 3 is between the first high-reflection coating 7 and the second high-reflection coating 8; the first high-reflection coating 7 is used for blocking the emission of light at the edge of the light guide material layer 3 to heat and keep warm the anti-fog heat conduction structure 5; the window protection glass 4 is arranged on the inner circumferential wall of the end of the annular heat conduction body 11 and is mainly used for sealing the lens of the endoscope, so that the internal lens is not affected by the external environment; the heat conduction ring 10 is arranged between the outer circumferential wall of the end of the window protection glass 4 and the inner circumferential wall of the end of the anti-fog heat conduction structure 5, the window protection glass 4 is the main device for fogging, the edge part of the window protection glass 4 is wrapped by the heat conduction ring 10, when the window protection glass 4 is connected to the anti-fog heat conduction structure 5, the heat conduction efficiency between the anti-fog heat conduction structure 5 and the window protection glass 4 can be effectively improved through the heat conduction ring 10, the temperature rising time of the window protection glass 4 is accelerated, and the fogging of the window protection glass 4 is further prevented. In addition, a third high-reflection coating 9 is coated between the outer surface of the light guide material layer 3 and the inner surface of the outer tube 1.

[0035] When the endoscope is used, the imaging clarity is reduced due to fogging of the window protection glass 4, so the window protection glass 4 is installed on the anti-fogging and heat-conducting structure 5. When the edge part of the light guide material layer 3 is blocked by the first high-reflection coating 7, that is, the optical fibers of the edge part of the light guide material layer 3 meet the blocked first high-reflection coating 7 at the exit end, the light cannot normally exit, and further, the light can be concentrated on the anti-fogging and heat-conducting structure 5, so that the light energy is converted into heat energy, and at the same time, the first high-reflection coating 7 can prevent the heat energy from escaping, so that the temperature of the anti-fogging and heat-conducting structure 5 rises. When the first high-reflection coating 7 on the anti-fogging and heat-conducting layer 6 is irradiated by the light in the light guide material layer 3, the temperature of the anti-fogging and heat-conducting structure 5 rises, and at the same time, the first high-reflection coating 7 enhances the heat preservation function, based on the principle of heat conduction, so that the temperature of the window protection glass 4 also rises, and at the same time, a certain temperature can be maintained for a long time, so that the endoscope lens anti-fogging is realized.

[0036] The light guide material layer 3 is used to conduct the illumination light generated from the cold light source device, the light enters from the tail end of the endoscope and exits from the head end of the endoscope, providing illumination for endoscope observation. During use of the endoscope, the cold light source device needs to work continuously, that is, part of the light exiting from the light source device will continuously enter the first high-reflection coating 7, the first high-reflection coating 7 will block the edge part of the light guide material layer 3, so that the light conducted by the edge part of the light guide material layer 3 enters the anti-fogging and heat-conducting layer 6, the light energy is continuously enriched on the anti-fogging and heat-conducting layer 6, and then the light energy is converted into heat energy, and the first high-reflection coating 7, the second high-reflection coating 8 and the third high-reflection coating 9 are used to store and heat lock the heat energy, which is not easy to lose, so that the temperature of the anti-fogging and heat-conducting structure 5 rises, the temperature of the front end of the endoscope is increased, and the endoscope anti-fogging effect is achieved. The heating and heat locking are used to heat the window protection glass 4 at the front end, the original working principle of the endoscope is maintained, and no additional heating device is added, which does not affect the service life of the endoscope.

[0037] At the same time, there is a certain length of the second high-reflection coating 8 and the third high-reflection coating 9 on the front half of the light guide material layer 3, which is used to collect the light energy lost due to fiber breakage during the transmission of light by the light guide material layer 3, and the lost light energy is reflected back by the second high-reflection coating 8 and the third high-reflection coating 9 to convert into heat energy, so that the front half of the endoscope is kept at a constant temperature, which can ensure that the window protection glass 4 does not produce fogging problems, and at the same time, the first high-reflection coating 7 on the anti-fogging and heat-conducting structure 5 can also be supplemented with heat.

[0038] It should be noted that in the present embodiment, the light guide material layer 3 and the heat conduction connecting layer 13 are both two and symmetrically arranged relative to the center of the annular heat conduction body 11; the fan-shaped positioning block 12 is two and symmetrically arranged relative to the center of the annular heat conduction body 11. In other embodiments, the heat conduction connecting layer 13 can be three, four, etc., and the design is not limited to the number and structure form in the present embodiment.
