Description

Technical Field

[0001] This invention relates to an endoscope cleaning device, specifically an endoscope lens cleaning device. Background Technology

[0002] Endoscopes are commonly used equipment in minimally invasive surgery. With the promotion of minimally invasive surgery, their application is becoming more and more widespread. Endoscopes can help observe and diagnose the affected area during minimally invasive surgery.

[0003] However, during the procedure, the endoscope lens may fog up due to the temperature difference between the inside and outside. Cutting operations during the procedure may also cause smoke to adhere to the lens surface. Additionally, liquid may adhere to the lens during the procedure, resulting in blurred and obstructed vision, hindering observation and affecting the progress of the surgery.

[0004] If the camera's field of vision is obstructed during surgery, the surgery cannot continue. The camera must be completely removed, cleaned, and then reinserted. This not only reduces surgical efficiency and prolongs the surgical time, but also affects the quality of the surgery. Repeated insertion and removal of the camera can also cause unnecessary damage to the affected area. Summary of the Invention

[0005] To address the problem that cleaning the endoscope lens is inconvenient in existing minimally invasive surgeries, and that cleaning requires removing the entire lens and then reinserting it, which affects surgical efficiency and quality, this invention provides an endoscope lens cleaning device.

[0006] The endoscope lens cleaning device provided by this invention can drive the transmission device at the rear of the endoscope cleaning device to wipe the lens if it becomes contaminated during surgery. This allows the cleaning of the surgical field of view to be completed without removing the endoscope. After cleaning, the transmission device can also move the cleaning block to a position that does not affect the field of view.

[0007] The specific technical solution of the present invention is as follows:

[0008] An endoscope lens cleaning device includes a sleeve and a handle disposed at one end of the sleeve. An inlet is provided inside the upper part of the handle. A main cavity and a secondary cavity are correspondingly disposed inside the sleeve and the handle. The main cavity corresponds to the size of the endoscope, and a drive wire is disposed inside the secondary cavity.

[0009] One end of the transmission wire is connected to one end of the connecting part inside the handle, and the other end of the transmission wire is equipped with a cleaning block, which is located in front of the opening at the front end of the sleeve. The middle part of the connecting part has a guide structure, and the surface of the guide structure is provided with a guide groove. The guide structure is wrapped inside the upper positioning block and the lower positioning block. A guide post is provided on the inner surface of the upper positioning block. The shape and position of the guide post correspond to the guide groove. After assembly, the guide post is placed in the guide groove. The outer surfaces of the upper positioning block and the lower positioning block are provided with external threads. The inner side of the adjuster is provided with internal threads that cooperate with the upper positioning block and the lower positioning block. The adjuster is set at the threads of the upper positioning block and the lower positioning block through threaded engagement. The adjuster is fixed to the corresponding position inside the handle by the limiting structure inside the handle. An opening is provided on the outer surface of the handle corresponding to the limiting structure and the adjuster. The adjuster part is exposed outside the handle.

[0010] A protrusion is fixedly installed at the top of the handle, and a silicone sleeve is fixedly installed on the protrusion. When the endoscope is inserted into the inlet and main cavity, the silicone sleeve can be fitted onto the fixing post on the endoscope to assist in fixing the endoscope. Inside the handle, from top to bottom, an upper limit structure, a limiting structure, an anti-rotation structure, and a lower limit structure are fixedly installed.

[0011] Furthermore, the transmission wire passes through the secondary cavity into the interior of the handle and connects to the transmission handle via the connecting part.

[0012] Furthermore, the upper part of the inlet of the handle has a groove that should match the fixing post 6-2 on the endoscope. When the endoscope is inserted into the handle and sleeve through the inlet, the fixing post enters the corresponding position of the groove. The silicone sleeve fixed on the upper protrusion of the handle is then placed on the fixing post to assist in fixing the endoscope.

[0013] Furthermore, a balance block is also provided on the upper and lower positioning blocks. The balance block has a square structure. When assembled into the handle, the balance block and the anti-rotation structure work together to restrict the rotation of the two positioning blocks. The other end of the upper and lower positioning blocks relative to the balance block is provided with a protrusion. This protrusion, in conjunction with the upper limit distance structure, can prevent the adjuster from adjusting the positioning block distance too much, which would cause the threads to come off. When the protrusion abuts against the upper limit distance structure, it cannot move upward any further.

[0014] Furthermore, the transmission handle includes a gripping part located outside the handle. One end of the connecting part is connected to the gripping part, and the connecting part passes through the handle and enters the handle. The other end of the connecting part is connected to the transmission wire. The guide structure is fixedly set in the middle of the connecting part and can rotate with the connecting part. The surface of the guide structure is provided with a guide groove. The guide groove is arc-shaped and divided into a high position and a low position. At the high position and the low position, there is a parallel groove of a certain length, which is at the same height and has a certain length. The high position groove and the low position groove are connected by an arc-shaped groove and form a continuous and uninterrupted guide groove on the surface of the guide structure.

[0015] In actual operation, in order to ensure that the guide post is in contact with the lens surface when it moves to the high position of the guide groove, the adjuster should be adjusted before use. By rotating the exposed part of the handle, the threaded engagement between the adjuster and the positioning block will rotate. The anti-rotation structure and the square engagement with the balance block prevent the positioning block from rotating when the thread rotates. The rotation of the adjuster will cause the two positioning blocks and the connecting parts, guide structure and guide post inside the positioning blocks to move relative to the handle. The cleaning block will be in contact with the lens when the guide post moves to the high position of the guide groove.

[0016] After the above conditions are met, the gripping part of the rotatable transmission handle can be rotated. At this time, the positioning block is fixed relative to the handle due to the threaded fit of the adjuster and the anti-rotation effect of the anti-rotation structure. The rotation of the gripping part drives the relative movement of the guide groove and the guide post. When the guide post moves to the high position groove, the cleaning block is exactly located on the lens surface when the endoscope is inserted and fixed. At this time, the guide post moves back and forth along a certain length of parallel section in the high position groove. At this time, the cleaning block does not move back and forth, but only rotates at a certain angle, which allows the cleaning block to rotate on the lens surface and be wiped. After the guide post moves from the high position groove to the low position groove, the guide post moves relative to the parallel section of a certain length in the low position groove, moving the cleaning block to a position that does not affect the lens field of view, thus completing the wiping of the lens.

[0017] Furthermore, the limiting structure consists of two plate-like structures fixed inside the handle, with no overlapping area between it and the upper and lower positioning blocks in the handle's extension direction. This ensures that the limiting structure only limits and fixes the adjuster. The distance between the two limiting structures is equal to the height of the adjuster, and the adjuster is fixed between the two limiting structures, so that the relative position of the adjuster and the handle does not change. An opening is provided on the surface of the handle corresponding to the adjuster, allowing part of the adjuster to be exposed on the outer surface of the handle. By rotating the part of the adjuster exposed on the handle, the relative position of the positioning block and its covered guide structure on the handle can be finely adjusted, thereby finely adjusting the distance between the cleaning block and the lens when the guide post moves to the high position groove, so that the cleaning block just abuts against the lens when the guide post moves to the high position groove.

[0018] The anti-rotation structure has a square groove in the middle that corresponds to the balance block. After assembly, since both the groove in the middle of the anti-rotation structure and the balance block are square, the rotation of the positioning block inside the handle is restricted. When the adjuster is rotated, the relative position of the adjuster on the external thread of the positioning block changes only by rotating the adjuster. The positioning block cannot rotate due to the action of the anti-rotation structure. The number of anti-rotation structures can be set according to requirements.

[0019] The positions of the upper and lower limit structures inside the handle can be determined based on the external thread on the positioning block and the size of the positioning block. Their purpose is to limit the distance the positioning block moves up and down when adjusted by the adjuster, preventing the internal thread of the adjuster from disengaging from the external thread of the positioning block. Furthermore, the upper and lower limit structures are equipped with through holes for the connecting part to pass through. The size of these through holes is not smaller than the cross-sectional size of the connecting part, but should be smaller than the cross-sectional size of the upper and lower positioning blocks after they are joined, in order to limit the movement of the positioning block.

[0020] In addition, the inventors have provided another feasible form of the endoscope lens cleaning device, whose main structure is the same as the above structure. The difference is that there is no limiting structure, lower limit structure, adjuster and anti-rotation structure inside the handle. Only a slide rail is fixed inside the handle. The shape of the slide rail corresponds to the balance block. The balance block can be moved back and forth in the slide rail by pushing the transmission handle through the grip.

[0021] Preferably, blocking structures are provided at both ends of the slide rail, allowing the balance block to move on the slide rail between the two blocking structures. In addition, the guide structure fixedly mounted on the connecting part of the transmission handle has a circular guide groove on its surface that is flush with the surface.

[0022] When cleaning the lens using the second type of cleaning device described above, first push the grip of the transmission handle forward to move the balance block in the slide rail. Rotate the grip to rotate the cleaning block to the lens. Then pull the grip backward to move the cleaning block back until it contacts the lens. At this point, rotate the grip to rotate the cleaning block as it contacts the lens, wiping and cleaning the lens. After cleaning, rotate the grip to rotate the cleaning block 2-1 to a position that does not obstruct the lens's field of view, and then pull the grip back.

[0023] More preferably, the position of the blocking structure at the high end of the slide rail can be adjusted so that when the balance block moves to the high end of the slide rail blocking structure, the cleaning block driven by it will just come into contact with the lens. When in use, push the grip forward until it can no longer be pushed, and then rotate the grip to drive the cleaning block to rotate and wipe the lens. At this time, the upper limit distance structure can be omitted at the high end of the positioning block, and the function of the upper limit distance structure is replaced by the blocking structure at the high end of the slide rail.

[0024] The endoscope lens cleaning device of the present invention achieves the following technical effects:

[0025] 1) Through the cooperation of the guide column and guide groove inside the transmission device in this endoscope cleaning device, the automatic advancement effect during rotation can be achieved, making operation convenient and quick;

[0026] 2) The position of the transmission device inside the handle can be finely adjusted by the adjustment mechanism exposed on the side of the handle, thereby finely adjusting the relative position of the cleaning block and the lens, so that the cleaning device can adapt to the size of lenses of various sizes.

[0027] 3) This device allows for cleaning of the endoscope lens without removing the endoscope, improving the efficiency, quality, and safety of the surgery. After cleaning, the cleaning block can be moved to a position that does not affect the lens's field of vision by operating the drive device. Attached Figure Description

Detailed Implementation

[0044] The technical solution of the present invention will be further described below with reference to specific embodiments. These embodiments are only used to illustrate the technical solution of the present invention in more detail and should not be construed as limiting the scope of protection of the present invention.

[0045] Example 1

[0046] Figure 1 The diagram shown is a side view of the first type of endoscope lens cleaning device, which includes a sleeve 1-2 and a handle 1 located at one end of the sleeve 1-2. An inlet 1-1 is provided inside the handle 1 for the endoscope 6 to enter. A main cavity 1-21 and a secondary cavity 1-22 are correspondingly provided inside the sleeve 1-2 and the handle 1. The main cavity 1-21 corresponds to the size of the endoscope 6 and the endoscope 6 can be inserted through the main cavity 1-21. A transmission wire 2 is provided inside the secondary cavity 1-22.

[0047] One end of the transmission wire 2 is connected to one end of the connecting part 3-3 inside the handle 1. The other end of the transmission wire 2 is equipped with a cleaning block 2-1, and the cleaning block 2-1 is located in front of the opening at the front end of the sleeve 1-2. The middle part of the connecting part 3-3 has a guide structure 3-4, and the surface of the guide structure 3-4 is provided with a guide groove 3-2. The guide structure 3-4 is wrapped inside the upper positioning block 4-1 and the lower positioning block 4-2. The inner surface of the upper positioning block 4-1 is provided with a guide post 4-4, and the shape and position of the guide post 4-4 correspond to the guide groove 3-2. That is, the guide post 4-4 is placed in the guide groove 3-2 after assembly.

[0048] The outer surfaces of the upper positioning block 4-1 and the lower positioning block 4-2 are respectively provided with external threads. The inner side of the adjuster 5 is provided with internal threads that cooperate with the upper positioning block 4-1 and the lower positioning block 4-2. The adjuster 5 is set at the threads of the upper positioning block 4-1 and the lower positioning block 4-2 through threaded engagement. The adjuster 5 is fixed to the corresponding position inside the handle 1 by the limiting structure 1-6 inside the handle 1. An opening is provided on the outer surface of the handle 1 corresponding to the limiting structure 1-6 and the adjuster 5, so that part of the adjuster 5 is exposed outside the handle 1.

[0049] A protrusion is fixedly provided on the top of the handle 1, and a silicone sleeve 1-3 is fixedly provided on the protrusion. When the endoscope 6 is inserted through to the inlet 1-1 and the main cavity 1-21, the silicone sleeve 1-3 can be fitted onto the fixing post 6-2 on the endoscope 6 to assist in fixing the endoscope 6.

[0050] Inside the handle 1, from top to bottom, are fixedly installed an upper limit distance structure 1-7, a limiting structure 1-6, an anti-rotation structure 1-4, and a lower limit distance structure 1-5.

[0051] The following explanation, in conjunction with the accompanying drawings, further clarifies the matter:

[0052] Figure 2 The diagram shows a cross-sectional view of the cannula 1-2. The cannula 2 is provided with a main cavity 1-21 and a secondary cavity 1-22. The size of the main cavity 1-21 corresponds to that of the endoscope 6. The secondary cavity 1-22 is provided with a transmission wire 2. The transmission wire 2 passes through the secondary cavity 1-22 and enters the interior of the handle 1, and is connected to the transmission handle 3 through the connecting part 3-3.

[0053] Figure 3 The diagram shows a top view of the endoscope cleaning device. After the adjuster 5 is fixed to the corresponding position of the handle 1 by the limiting structure 1-6, an opening is provided on the handle 1 corresponding to the adjuster 5 and the limiting structure 1-6. Part of the adjuster 5 is exposed outside the handle 1 through the opening. There is a groove on the upper part of the inlet 1-1 of the handle 1. The groove corresponds to and cooperates with the fixing post 6-2 on the endoscope 6. When the endoscope 6 is inserted into the handle 1 and the sleeve 1-2 through the inlet 1-1, the fixing post 6-2 enters the corresponding position of the groove. The silicone sleeve 1-3 fixed on the upper protrusion of the handle 1 is put on the fixing post 6-2 to assist in fixing the endoscope 6.

[0054] Figure 4 and Figure 5The diagram shows the upper positioning block 4-1 and the lower positioning block 4-2. The inner surface shapes of the upper positioning block 4-1 and the lower positioning block 4-2 correspond to the guide structure 3-4 and can be combined to cover the guide structure 3-4. A protruding guide post 4-4 is provided on the inner surface of the upper positioning block 4-1. The shape and position of the guide post 4-4 correspond to the guide groove 3-2 on the guide structure 3-4. After assembly, the guide post 4-4 is inserted into the guide groove 3-2 and can move inside the guide groove 3-2. The outer surfaces of the upper positioning block 4-1 and the lower positioning block 4-2 are provided with corresponding external threads. After splicing and assembly, the external threads form a whole. The internal thread on the inner side of the adjuster 5 corresponds to the upper positioning block 4-1. The external thread engagement allows for assembly with the two assembled positioning blocks. A balance block 4-3 is also provided on the upper positioning block 4-1 and lower positioning block 4-2, with a square structure. When assembled into the handle 1, the balance block 4-3, in conjunction with the anti-rotation structure 1-4, restricts the rotation of the two positioning blocks. A protrusion is provided on the other end of the upper positioning block 4-1 and lower positioning block 4-2 opposite to the balance block 4-3. This protrusion, in conjunction with the upper limit distance structure 1-7, prevents the adjuster 5 from adjusting the positioning block distance too much, causing the thread to come loose. When the protrusion contacts the upper limit distance structure 1-7, it cannot move upwards further.

[0055] The structure of the transmission handle 3 is as follows Figure 6 and Figure 7 As shown, the device includes a gripping part 3-1 located outside the handle 1. One end of a connecting part 3-3 is connected to the gripping part 3-1. The connecting part 3-3 passes through the handle 1 and enters the interior of the handle 1. The other end of the connecting part 3-3 is connected to the transmission wire 2. A guide structure 3-4 is fixedly installed in the middle of the connecting part 3-3 and can rotate with the connecting part 3-3. The surface of the guide structure 3-4 is provided with a guide groove 3-2. The guide groove 3-2 is arc-shaped and divided into a high position and a low position. The guide groove 3-2 has a parallel groove of a certain length at the high position and the low position, which is called the high position groove and the low position groove. The high position groove and the low position groove are connected by an arc-shaped groove and form a continuous and uninterrupted guide groove 3-2 on the surface of the guide structure 3-4.

[0056] To ensure that the guide post 4-4 moves to the high position of the guide groove 3-2 and abuts against the surface of the lens 6-1, the adjuster 5 is first adjusted before use. By rotating the exposed part of the handle 1, the threaded engagement between the adjuster 5 and the positioning block is rotated. The square engagement between the anti-rotation structure 1-4 and the balance block 4-3 prevents the positioning block from rotating when the thread rotates. The rotation of the adjuster 5 causes the two positioning blocks and the connecting part 3-3 inside the positioning blocks, the guide structure 3-4 and the guide post 4-4 to move relative to the handle 1. The cleaning block 2-1 abuts against the lens 6-1 when the guide post 4-4 moves to the high position of the guide groove 3-2.

[0057] After adjusting the guide post 4-4 to the high position of the guide groove 3-2, ensuring that the cleaning block 2-1 abuts against the lens 6-1, the gripping part 3-1 of the drive handle 3 can be rotated. At this time, the positioning block is fixed relative to the handle 1 due to the threaded fit of the adjuster 5 and the anti-rotation effect of the anti-rotation structure 1-4. The rotation of the gripping part 3-1 drives the relative movement between the guide groove 3-2 and the guide post 4-4. When the guide post 4-4 moves to the high position groove, the cleaning block 2-1 is exactly positioned when the endoscope 6 is inserted and fixed. At the position of the lens 6-1 surface, the guide post 4-4 moves back and forth along a certain length of parallel section in the high position groove. At this time, the cleaning block 2-1 does not move back and forth, but only rotates at a certain angle, allowing the cleaning block 2-1 to rotate on the surface of the lens 6-1 and be wiped. After the guide post 4-4 moves from the high position groove to the low position groove, the guide post 4-4 moves relative to the parallel section of a certain length in the low position groove, moving the cleaning block 2-1 to a position that does not affect the field of view of the lens 6-1, thus completing the wiping of the lens 6-1.

[0058] Figure 8 The diagram shows the regulator 5. The regulator 5 is preferably a nut structure with an internal thread that mates with the external threads of the upper positioning block 4-1 and the lower positioning block 4-2 after assembly. After the two positioning blocks are joined together, the regulator 5 can be rotated to its external thread, making the regulator 5 and the two positioning blocks a single unit. Figure 9 The diagram shown is a schematic of the assembled regulator 5, upper positioning block 4-1, lower positioning block 4-2 and guide structure 3-4.

[0059] The structure in which the two positioning blocks, the adjuster 5, and the guide structure 3-4 enclosed by the positioning blocks are fixed inside the handle 1 is as follows: Figure 10 As shown.

[0060] The limiting structure 1-6 is a two-layer plate-like structure fixed inside the handle 1, and it has no overlapping area with the upper positioning block 4-1 and the lower positioning block 4-2 in the extension direction of the handle 1, so as to ensure that the limiting structure 1-6 only limits and fixes the adjuster 5. The distance between the two limiting structures 1-6 is equal to the height of the adjuster 5. The adjuster 5 is fixed between the two limiting structures 1-6, so that the relative position of the adjuster 5 and the handle 1 does not change. An opening is provided on the surface of the handle 1 corresponding to the adjuster 5, so that part of the adjuster 5 is exposed on the outer surface of the handle 1. By rotating the part of the adjuster 5 exposed on the handle 1, the relative position of the positioning block and the guide structure 3-4 it covers on the handle 1 can be finely adjusted, thereby finely adjusting the distance between the cleaning block 2-1 and the lens 6-1 when the guide post 4-4 moves to the high position groove, so that the cleaning block 2-1 just abuts against the lens 6-1 when the guide post 4-4 moves to the high position groove.

[0061] The anti-rotation structure 1-4 has a square groove in the middle that corresponds to the balance block 4-3. After assembly, since the groove in the middle of the anti-rotation structure 1-4 and the balance block 4-3 are both square, the rotation of the positioning block inside the handle 1 is restricted. When the adjuster 5 is rotated, the relative position of the adjuster 5 on the external thread of the positioning block changes only by the rotation of the adjuster 5. The positioning block cannot rotate due to the action of the anti-rotation structure 1-4.

[0062] The number of anti-rotation structures 1-4 can be set according to requirements. In this embodiment, two sets of anti-rotation structures 1-4 are set. The purpose is that when the positioning block moves relative to the handle 1 due to the rotation of the regulator 5, the balance block 4-3 will never leave the limiting range of the anti-rotation structure 1-4, and it is beneficial to maintain balance and avoid tilting during the process, which would affect the operation.

[0063] Inside the handle 1, an upper limit distance structure 1-7 and a lower limit distance structure 1-5 are also provided. The positions of the upper limit distance structure 1-7 and the lower limit distance structure 1-5 can be determined according to the external thread on the positioning block and the size of the positioning block. The purpose is to limit the distance of movement of the positioning block when the adjusting device 5 adjusts the up and down movement, so that the internal thread of the adjusting device 5 will not come out of the external thread of the positioning block.

[0064] The upper limit distance structure 1-7 and the lower limit distance structure 1-5 are provided with through holes for the connecting part 3-3 to pass through. The size of the through hole is not less than the cross-sectional size of the connecting part 3-3, but should be smaller than the cross-sectional size of the upper positioning block 4-1 and the lower positioning block 4-2 after they are combined, so as to limit the movement of the positioning block.

[0065] Figure 13 and Figure 15 This diagram illustrates how the cleaning block 2-1 is moved to the high position slot to clean the lens 6-1 during actual use. At this time, the endoscope 6 has been assembled into the endoscope cleaning device through the inlet 1-1 and the main cavity 1-21, and the silicone sleeve 1-3 has been fixed to the fixing post 6-2 on the endoscope 6. The puncture tube 7 is fitted onto the sleeve 1-2. When the lens 6-1 of the endoscope 6 is inserted into the human body for examination, if phenomena such as fogging, smoke from cutting, or liquid adhesion occur on the surface of the lens 6-1, obstructing the field of vision and hindering observation, the gripping part 3-1 is rotated to drive the relative movement of the guide groove 3-2 and the guide post 4-4. When the guide post 4-4 moves to the high position slot of the guide groove 3-2, the position of the cleaning block 2-1 corresponds to the position of the lens 6-1. The guide post 4-4 is moved back and forth in the parallel section with a certain length in the high position slot, so that the cleaning block 2-1 can be rotated and cleaned at the lens 6-1.

[0066] After cleaning, rotate the grip 3-1 to move the guide groove 3-2 and guide post 4-4 relative to each other. The guide post 4-4 moves to the lower part of the guide groove 3-2 and then moves within a parallel section of a certain length in the lower part of the groove. Rotate the cleaning block 2-1 to a position that does not obstruct the field of view of the lens 6-1. Figure 14 As shown.

[0067] It should be noted that, in order to ensure that the guide post 4-4 moves to the high position of the guide groove 3-2 and just abuts against the surface of the lens 6-1, the adjuster 5 should be adjusted before use. By rotating the adjuster 5 at the exposed part of the handle 1, the two guide posts will move relative to the handle 1 until the guide post 4-4 moves to the high position of the guide groove 3-2 and just abuts against the lens 6-1.

[0068] Example 2

[0069] The main structure of the endoscope lens cleaning device is the same as that of Embodiment 1, except that the limiting structure 1-6, the lower limit structure 1-5, the adjuster 5, and the anti-rotation structure 1-4 are not provided inside the handle 1. Instead, a slide rail 1-8 is fixed inside the handle 1. The shape of the slide rail corresponds to and matches the balance block 4-3. The balance block 4-3 can be moved back and forth in the slide rail 1-8 by pushing the transmission handle 3 through the grip 3-1. Figure 11 As shown.

[0070] A blocking structure is provided at both ends of the slide rail 1-8, and the balance block 4-3 can move on the slide rail 1-8 between the two blocking structures.

[0071] It should be noted that in this embodiment, whether or not the upper limit distance structure 1-7 is set is irrelevant. The function and corresponding effect of this embodiment can still be achieved without setting the upper limit distance structure 1-7, because the blocking structure at one end of the slide rail 1-8 plays the same role as the upper limit distance structure 1-7.

[0072] In this embodiment, as Figure 12 As shown, the guide structure 3-4 is fixedly installed on the connecting part 3-3 of the transmission handle 3. The guide groove 3-2 on its surface is a circular groove, and the guide groove 3-2 has no high and low displacement as in Embodiment 1, and is flush with the whole.

[0073] When cleaning the lens using the cleaning device described in this embodiment, first push the gripping part 3-1 of the transmission handle 3 forward to move the balance block 4-3 in the slide rail 1-8, rotate the gripping part 3-1 to rotate the cleaning block 2-1 to the lens 6-1, and then pull the gripping part 3-1 backward to move the cleaning block 2-1 backward to abut against the lens 6-1. At this time, rotate the gripping part 3-1 to rotate the cleaning block 2-1 when it abuts against the lens 6-1 to wipe and clean the lens 6-1.

[0074] After cleaning, rotate the grip 3-1 to rotate the cleaning block 2-1 to a position that does not affect the field of view of the lens 6-1, and then pull the grip 3-1 back.

[0075] More preferably, the position of the blocking structure at the high end of the slide rail 1-8 can be adjusted so that when the balance block 4-3 moves to the high blocking structure of the slide rail 1-8, the cleaning block 2-1 driven by it will just abut against the lens 6-1. When in use, push the grip 3-1 forward until it can no longer be pushed, and then rotate the grip 3-1 to drive the cleaning block 2-1 to rotate and wipe the lens 6-1. At this time, the upper limit distance structure 1-7 can be omitted at the high end of the positioning block, and the function of the upper limit distance structure 1-7 is replaced by the blocking structure at the high end of the slide rail 1-8.

[0076] Alternatively, an upper limit distance structure 1-7 can be set at the high end of the positioning block, and its position can be preset so that when the positioning block and the upper limit distance structure 1-7 are in contact, the cleaning block 2-1 is exactly in contact with the lens 6-1.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the spirit and principle of the present invention without any creative effort should be included within the protection scope of the present invention.
