Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and more specifically to a scrubbing mechanism. Background Art

[0002] With the development of modern medicine, endoscopes are increasingly used in minimally invasive surgeries. Specifically, the endoscope is passed through the mouth into the stomach or into the body through other natural orifices.

[0003] An endoscope usually includes an operating part, an insertion part and a connecting part, wherein the insertion part includes an insertion tube and a tip located at the head end of the insertion tube, and a camera unit, a lighting unit, a working forceps channel, a water vapor channel, etc. are provided inside the insertion part. The tail end of the insertion tube is connected to one side of the operating part, and a connecting part is provided on the other side of the operating part to connect to a host and a display. When in use, the insertion part is inserted into the human body from the oral cavity or other natural orifices of the human body, and the medical staff holds the operating part to control the position of the tip in the human body. The treatment instrument extends from the tip through the working forceps channel to sample or treat the patient's lesion location.

[0004] Endoscopes are invasive instruments and are contaminated with many types of contaminants, including proteins, mucopolysaccharides, fats and carbohydrates. If the endoscopes are not cleaned and disinfected, cross infection is very likely to occur, endangering the health and life safety of patients. The routine operations for cleaning and disinfecting endoscopes are as follows: manually scrub the outside of the endoscope, fill the inner cavity of the endoscope with liquid and air to achieve bedside pre-cleaning of the endoscope, then transport the endoscope to the disinfection room and immerse the endoscope in the disinfectant, fill the inner cavity of the endoscope with liquid, hold a soft cloth to wipe the outer surface of the endoscope, hold a brush to scrub the inner cavity wall of the endoscope, and finally fill the endoscope with liquid again to complete the cleaning and disinfection of the endoscope.

[0005] However, when manually cleaning and disinfecting endoscopes, medical staff are required to hold a soft cloth and repeatedly wipe the outer surface of the endoscope. This operation is cumbersome, and the cleanliness of each cleaning process by different medical staff is difficult to ensure.

[0006] In summary, how to ensure the cleanliness of the outer surface of the endoscope after scrubbing is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] The core of the utility model is to provide a scrubbing mechanism, through which the endoscope can be automatically scrubbed to effectively ensure the cleanliness thereof.

[0045] Please refer to Figure 1 The utility model provides a scrubbing mechanism, comprising a moving assembly 1 and a scrubbing assembly 2. The moving assembly 1 comprises a linear slide rail 11 extending in a first direction and a sliding assembly 12 slidably arranged on the linear slide rail 11; the scrubbing assembly 2 comprises a driving assembly 21 and a cleaning assembly 22, the output end of the sliding assembly 12 is fixedly connected to the cleaning assembly 22 to drive the cleaning assembly 22 to move along the linear slide rail 11, and the cleaning assembly 22 is connected to the driving assembly 21 to drive the cleaning assembly 22 to approach or move away from the tubular structure to be scrubbed.

[0046] like Figure 1 As shown, the linear slide rail 11 is placed horizontally, and the sliding assembly 12 is placed on the linear slide rail 11. Then, under the drive of the linear slide rail 11, the sliding assembly 12 can slide horizontally, and the scrubbing assembly 2 installed on the sliding assembly 12 can slide therewith.

[0047] Furthermore, the cleaning component 22 may adopt a sheet-shaped or clip-shaped cleaning wipe, and under the drive of the driving component 21, the cleaning component 22 may rotate or slide, so that the cleaning component 22 may be close to or away from the tubular structure to be scrubbed. Optionally, the driving component 21 may adopt a motor and a reducer, and the cleaning component 22 is arranged at the output end of the reducer, so that the driving component 21 can drive the cleaning component 22 to rotate while outputting rotation. Optionally, the driving component 21 may adopt a motor, a gear and a rack, and the cleaning component 22 is connected to the rack, so that the driving component 21 can drive the cleaning component 22 to move in a straight line while outputting linear motion. Of course, the output component can also adopt any other type of structure, as long as it can drive the cleaning component 22 to be close to or away from the tubular structure to be scrubbed.

[0048] When in use, the tubular structure to be scrubbed is laid at a preset position. At this time, the tubular structure to be scrubbed extends laterally, the sliding component 12 and the driving component 21 are started, and the cleaning component 22 is driven to approach the tubular structure to be scrubbed, and then the cleaning component 22 is driven to move laterally to continuously scrub the tubular structure. After the cleaning component 22 moves to the end, the cleaning component 22 is driven away from the tubular structure to complete the scrubbing of the tubular structure. The endoscope can be automatically scrubbed by the scrubbing mechanism to effectively ensure the cleanliness of each endoscope.

[0049] On the basis of the above-mentioned embodiment, the driving component 21 includes a shell 211, an elastic member 212, a guide member 213 and a movable member 214; the shell 211 is fixedly connected to the output end of the sliding component 12; the guide member 213 is inserted into the interior of the shell 211 along a first direction, and the guide member 213 can slide relative to the shell 211, and the bottom end of the circumference of the middle shaft section of the guide member 213 is gradually reduced in size along the first direction; the movable member 214 is inserted into the interior of the shell 211 along a second direction, the second direction is perpendicular to the first direction, and the movable member 214 can slide relative to the shell 211; the elastic member 212 is sleeved on the outside of the movable member 214, and the top end of the elastic member 212 abuts the movable member 214, and the bottom end abuts the shell 211; the top end of the movable member 214 abuts against the bottom end of the circumference of the guide member 213 and can move relatively; the bottom end of the movable member 214 is connected to the cleaning component 22 to drive the cleaning component 22.

[0050] like Figure 5As shown, the housing 211 is a hollow structure for mounting and supporting the elastic member 212, the guide member 213 and the movable member 214, wherein the guide member 213 is arranged on the housing 211, and the movable member 214 is arranged on the housing 211 in a direction perpendicular to the guide member 213, and the guide member 213 and the movable member 214 can slide relative to the housing 211 in their own directions; furthermore, the middle part of the guide member 213 is a variable cross-section shaft section, and optionally, the cross-section shape of the shaft section along its length direction is an isosceles trapezoid, and optionally, the shaft section along its length direction is a variable cross-section shaft section. The cross-sectional shape is a right-angled trapezoid, etc., and the variable-section position of the rotating shaft can contact the movable part 214. When the external force pushes the guide part 213 to slide relative to the shell 211, the movable part 214 can contact the circumferential surface of the variable-section shaft segment in the guide part 213; secondly, an elastic part 212 is sleeved on the circumferential surface of the movable part 214. The elastic part 212 can be a linear spring or a torsion spring, etc., and the elastic part 212 is always in a contracted state, so that the elastic part 212 provides a push for the movable part 214 to have a movement tendency close to the guide part 213.

[0051] by Figures 1 to 5 As a reference, when in use, the sliding component 12 drives the shell 211 fixedly connected thereto, thereby driving the entire driving component 21 in this embodiment to move horizontally. After the driving component 21 moves to the left end, a force toward the right end is applied to the guide member 213, so that the guide member 213 moves to the right. During the movement, under the action of the variable-section shaft section and the elastic member of the guide member 213, the movable member 214 moves downward. Conversely, after the driving component 21 moves to the right end, a force toward the left end is applied to the guide member 213, so that the guide member 213 moves to the left. During the movement, under the action of the variable-section shaft section and the elastic member of the guide member 213, the movable member 214 moves upward. With such a configuration, the scrubbing mechanism has a simple structure and is effectively energy-saving.

[0052] Optionally, the cleaning component 22 is rotatably connected to the shell 211 and the movable member 214 . When in use, the cleaning component 22 can be driven to rotate relative to the shell 211 by the pushing or pulling action of the movable member 214 .

[0053] Optionally, the cleaning component 22 is fixedly connected to the movable part 214 , and when in use, the cleaning component 22 can be driven to rise and fall under the pushing or pulling action of the movable part 214 .

[0054] On the basis of the above-mentioned embodiment, the top end of the movable member 214 is movably matched with the circumference of the guide member 213 through the rotating disc structure 215 .

[0055] like Figure 5As shown, a rotatable disc structure 215 is provided at the upper end of the movable part 214, and the movable part 214 can roll with the guide part 213 through the disc structure 215, thereby effectively reducing the movement resistance of the driving component 21, reducing the wear of the movable part 214 and the guide part 213, and extending the service life of the scrubbing mechanism.

[0056] On the basis of the above embodiment, it also includes a limit component 3, which includes a first limit member 31 and a second limit member 32. The first limit member 31 is located at one end of the linear guide rail 11, and the second limit member 32 is located at the other end of the linear guide rail 11. The scrubbing component 2 can abut against the first limit member 31 or the second limit member 32.

[0057] like Figures 1 to 3 As shown, a first limit member 31 is provided at the left end of the linear guide rail 11, and a second limit member 32 is provided at the right end. It should be noted that the first limit member 31 and the second limit member 32 may be the same or different, and the types of the first limit member 31 and the second limit member 32 are not limited, as long as they can cooperate with the scrubbing component 2 to achieve its limitation.

[0058] Preferably, Figures 1 to 3 As shown, the second limit member 32 is a door-type structure, and the movable component 1 is arranged on the top beam of the second limit member 32, while the first limit member 31 adopts an L-shaped structure, and one end of the first limit member 31 is connected to the second limit member 32, and the other end cooperates with the scrubbing component 2 to realize the function. With such an arrangement, the structural stability of the scrubbing mechanism is relatively high, and it is convenient to stably install the scrubbing mechanism on other cleaning equipment.

[0059] Optionally, the housing 211 of the driving assembly 21 and / or the cleaning assembly 22 may abut against the first limiting member 31 and the second limiting member 32. Figures 1 to 5 Taking the orientation as a reference, after the sliding component 12 drives the driving component 21 to move horizontally to the left end, the shell 211 and / or the cleaning component 22 abut against the first limiting member 31 located on the left side, and apply a force toward the right end to the guide member 213, so that the guide member 213 moves to the right. During the movement, under the action of the variable-section shaft section and the elastic member of the guide member 213, the movable member 214 moves downward. Conversely, after the sliding component 12 drives the driving component 21 to move horizontally to the right end, the shell 211 and / or the cleaning component 22 abut against the second limiting member 32 located on the right side, and apply a force toward the left end to the guide member 213, so that the guide member 213 moves to the left. During the movement, under the action of the variable-section shaft section and the elastic member of the guide member 213, the movable member 214 moves upward. Such a configuration makes it easy to control the end position of the movement of the scrubbing component 2.

[0060] Optionally, an end of the guide member 213 in the driving assembly 21 may abut against the first limiting member 31 or the second limiting member 32 .

[0061] like Figures 1 to 3 As shown, the first stopper 31 and the second stopper 32 can contact the guide member 213. Figures 1 to 5 Taking the orientation as a reference, when the sliding assembly 12 drives the driving assembly 21 to move laterally toward the left side, the left end of the guide member 213 first abuts against the first limiting member 31 located on the left side, and the driving assembly 21 continues to move to the left under the drive of the sliding assembly 12. At this time, the guide member 213 does not move, and the shell 211 drives the movable member 214 to continue to move to the left, and under the action of the variable-section shaft section and the elastic member of the guide member 213, the movable member 214 moves downward. Conversely, when the sliding assembly 12 drives the driving assembly 21 to move laterally toward the left side, the left end of the guide member 213 first abuts against the second limiting member 32 located on the right side, and the driving assembly 21 continues to move to the right under the drive of the sliding assembly 12. At this time, the guide member 213 does not move, and the shell 211 drives the movable member 214 to continue to move to the right, and under the action of the variable-section shaft section and the elastic member of the guide member 213, the movable member 214 moves upward.

[0062] In this embodiment, the first limiting member 31 and the second limiting member 32 physically block the guide member 213 to drive the movable member 214 to achieve movement in a preset direction. With this arrangement, the scrubbing mechanism is automated and has a simple and reliable structure.

[0064] The first force arm 222 and the second force arm 223 can be a rod-shaped structure or a triangular plate-shaped structure, wherein Figure 4 and Figure 5 As shown, the first lever arm 222 has three non-co-located connecting parts, one connecting part of the first lever arm 222 is used to fixedly connect the scrubbing member 221, another connecting part is used to rotatably connect the shell 211, and the remaining connecting part is used to rotatably connect the third lever arm 224. The second lever arm 223 has two connecting parts, one connecting part of the second lever arm 223 is used to rotatably connect the first lever arm 222, and the other connecting part is movably connected to the movable member 214. Optionally, the movable member 214 is rotatably connected to the second lever arm 223.
