[0002] Endoscopes are increasingly common in clinical practice, allowing doctors to observe the characteristics of patient lesions and tailor treatment plans accordingly. After using an endoscope, medical staff must scrub the openings, including the suction port, biopsy port, and water and air supply ports. The existing cleaning method requires medical staff to select an appropriate brush based on the diameter of the opening and then manually scrub the endoscope up and down. This is cumbersome, and the lack of a rotating cleaning mechanism results in poor cleaning results.

[0003] To this end, we have designed an electric brush that can automatically rotate and clean endoscopes. The appropriate brush can be plugged in according to the diameter of the tube orifice, and can realize the rotational cleaning of the endoscope. It has a good cleaning effect, reduces the workload of medical staff, improves cleaning efficiency, and the brush is easy to disassemble and assemble, and is highly practical. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0019] See also Figure 1-4 The present embodiment provides an electric brush for cleaning endoscopes, comprising a handle 1 and a brush rod 13, the end of the brush rod 13 is provided with bristles 14, an opening 2 is provided on the front side of the handle 1, and a rotating shaft 3 is rotatably provided at the bottom of the opening 2. As a conventional design, a motor 15 for driving the rotating shaft 3 to rotate should be provided in the handle 1, a connecting sleeve 7 is inserted in the opening 2, a rotating rod 8 is rotatably provided in the middle of the connecting sleeve 7, the head of the rotating rod 8 is connected to the brush rod 13, and the rotating shaft 3 can drive the rotating rod 8 to rotate, a limiting component for fixing the connecting sleeve 7 is provided in the opening 2, and in order to facilitate the disassembly of the connecting sleeve 7, a sliding sleeve 9 for allowing the limiting component to release the limit of the connecting sleeve 7 is provided on the outer wall of the handle 1; specifically, the limiting component includes a plurality of mounting openings 20 evenly opened on the side wall of the opening 2, a limiting ball 12 is movably provided in the mounting opening 20, and a limiting groove 18 corresponding to the limiting ball 12 is provided on the outer wall of the connecting sleeve 7. Its structure is as follows Figure 3 As shown, the sleeve 9 is slidably mounted on the outside of the handle 1, and a raised pressure ring 17 is provided on the inner side of the sleeve 9. The raised pressure ring 17 contacts one end of the limiting ball 12, and the other end of the limiting ball 12 is pressed into the limiting groove 18. A fixing ring 10 and a limiting ring 16 are provided on the outer wall of the handle 1 on both sides of the raised pressure ring 17, and a second spring 11 is provided between the fixing ring 10 and the raised pressure ring 17.

[0020] It should be noted that, as a common sense, the inner side of the mounting opening 20 should be a tapered opening to prevent the limiting ball 12 from escaping from the inner side of the mounting opening 20; at the same time, the shape of the sliding sleeve 9 and the raised pressure ring 17 is as follows: Figure 2 As shown, when the raised pressure ring 17 leaves the mounting opening 20, the sliding sleeve 9 can prevent the limiting ball 12 from escaping from the outside of the mounting opening 20. Its structure should be a conventional shape structure familiar to those skilled in the art, and will not be described in detail in this application.

[0021] In addition, it should be noted that a clamping platform 21 corresponding to the connecting sleeve 7 can be designed in the opening 2 to achieve the positioning of the connecting sleeve 7. This is a conventional design familiar to those skilled in the art and will not be described in detail in this application.

[0022] At the same time, in order to facilitate the disassembly of the connecting sleeve 7, an ejection assembly for ejecting the connecting sleeve 7 out of the opening 2 is provided on the rotating shaft 3. Specifically, the ejection assembly includes a top sleeve 4, the tail of the top sleeve 4 is slidably sleeved on the rotating shaft 3, a support ring 5 is provided at the tail of the rotating shaft 3, a first spring 6 is provided between the support ring 5 and the top sleeve 4, a plug 19 is provided at the tail of the rotating rod 8, and the plug 19 is inserted into the head of the top sleeve 4. Among them, as a conventional design, the plug 19 preferably adopts a cross plug, and it is only necessary to open a corresponding cross jack at the top of the top sleeve 14.

[0023] It should be noted that in actual applications, as a conventional design, the motor 15 should be a rechargeable motor, and a corresponding battery can also be designed in the handle 1. At the same time, a corresponding control button 22 should also be designed on the handle 1, so that the appearance of the handle 1 is similar to the handle of an electric toothbrush, which can facilitate the operation of medical staff. During processing, it can be designed to an appropriate size, and this application will not go into details.

[0024] In actual application, when it is necessary to connect the handle 1 with the brush rod 13, pull down the sleeve 9, insert the connecting sleeve 7 into the opening 2, insert the plug 19 at the bottom of the rotating rod 8 into the top sleeve 4, and press the top sleeve 4 to move down. When the bottom of the connecting sleeve 7 contacts the card table 21, release the sleeve 9, and the second spring 11 causes the sleeve 9 to move up and reset. During this process, the connecting sleeve 7 is rotated at the same time. When the position of the limiting ball 12 corresponds to the limiting groove 18 of the connecting sleeve 7, the limiting ball 12 is pressed into the limiting groove 18 to limit the connecting sleeve 7. By operating the control button 22, the brush rod 13 can be driven to rotate, and the endoscope can be brushed. It should be noted that, for better operation, multiple limiting grooves 18 can be directly designed as an integrated annular groove, and there is no need to rotate the connecting sleeve 7 when plugging in. This is a conventional structural replacement familiar to those skilled in the art, and this application will not go into details.

[0025] When the handle 1 and the brush rod 13 need to be separated, Figure 2 As shown, it is only necessary to pull down the sliding sleeve 9 so that the raised pressure ring 17 no longer presses the limiting ball 12. At this time, the first spring 6 pushes the top sleeve 4 to move upward, so that the connecting sleeve 7 moves upward, and the limiting ball 12 is squeezed into the installation port 20, and the connecting sleeve 7 can be pushed out of the opening 2, so that the handle 1 and the brush rod 13 can be easily separated.

[0026] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, solutions or features that belong to the prior art or common knowledge will not be described in detail in the above embodiments.

[0027] In addition, the technical solutions of the present application are not limited to the above-mentioned embodiments. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
