Description

Technical Field

[0001] This invention relates to the field of endoscope tubing cleaning technology, and in particular to a device and its working method for cleaning endoscope tubing. Background Technology

[0002] In gastroenterology clinical practice, endoscopes are commonly used diagnostic and treatment instruments, and the cleanliness of their internal tubing directly affects the safety of diagnosis and treatment. Therefore, endoscopic tubing cleaning is an indispensable post-treatment step. Currently, most endoscopic tubing cleaning in this field is done manually. The operator holds the cleaning tool's thread, inserts a bristle-equipped cleaning component into the endoscopic tubing, and then manually pulls the thread to move the cleaning component within the tubing to remove contaminants from the inner wall. In addition, some simple auxiliary cleaning tools exist, but the core operation still relies on manual labor.

[0003] The existing manual cleaning methods have significant technical problems, namely poor operational convenience. Because endoscope tubing typically has a curved or inclined structure, manually pulling the suture to repeatedly insert and remove the cleaning component requires operators to precisely control the force and direction to avoid suture jamming or tubing damage. Furthermore, the repeated pulling motion is cumbersome and labor-intensive, consuming considerable manpower and time, severely impacting the efficiency and user experience of endoscope tubing cleaning. Summary of the Invention

[0004] To address the shortcomings mentioned above in the background art, the present invention provides a device and its working method for cleaning endoscope tubing.

[0005] The present invention adopts the following technical solution: In a first aspect, the present invention provides an apparatus for cleaning endoscopic tubing, the apparatus comprising a placement plate and a guide device, the placement plate being used to place an endoscope, and the guide device being disposed on the placement plate, the guide device comprising: A fixing frame is fixed to the placement plate, with an arc-shaped rail at one end and a straight rail at the other end. A slider adapted to slide along the linear track; A connector, one end of which is provided with a slide rod, which passes through the slider with clearance fit, and the slide rod is perpendicular to the linear rail; A swing frame, one end of which is provided with two rotatable guide wheels, the other end of which is pivotally connected to the connecting member, and an arc-shaped groove is provided on the swing frame, which is adapted to fit outside the arc-shaped rail, so that the swing frame swings along the arc-shaped rail. A drum is disposed within the swing frame and rotates therein. A drive motor is fixed on the swing frame and drives the drum to rotate. A cleaning brush, wherein the filaments of the cleaning brush are wound inside the spool and pass through the two guide wheels, such that the brush bar of the cleaning brush is located between the two guide wheels on the side away from the swing frame; After the endoscope to be cleaned is placed on the placement plate, the connection hole of the endoscope is located at the middle of one end of the arc-shaped rail corresponding to the fixing frame.

[0006] In one possible implementation of the first aspect, upright plates are fixed on both sides of the fixing frame, and a crossbeam is fixed between the two upright plates. The crossbeam is provided with a strip hole, the length extension direction of the strip hole is parallel to the length extension direction of the straight rail, and a threaded second bolt is adapted to be connected to the connector. The stud of the second bolt passes through the strip hole and is threadedly connected to the connector.

[0007] In one possible implementation of the first aspect, the two sides of the fixed frame are support rods, the two ends of the arc-shaped rail are respectively fixed to the two support rods, the arc-shaped groove is sleeved behind the arc-shaped rail, and the swing frame is fixed with a sealing plate on the arc-shaped groove.

[0008] In one possible implementation of the first aspect, one of the guide wheels and the drum are connected by a drive.

[0009] In one possible implementation of the first aspect, the annular surface of the guide wheel forms a recessed groove, and the cleaning brush passes through the groove of the two guide wheels in an interference fit.

[0010] In a possible implementation of the first aspect, the device further includes a locking device, the locking device comprising: A cylindrical base is fixed to the placement plate, and the cylindrical base is provided with a wire through hole that passes through both ends of the cylindrical base; The comb teeth have a recessed groove on one side, and multiple comb teeth are distributed in a ring around the axis of the threading hole at one end of the cylinder seat. An elastic band is fitted over the slot of each of the comb teeth, and the elastic force of the elastic band's annular contraction brings each of the comb teeth together toward the axis of the threading hole. After the endoscope is placed on the placement plate, the water inlet of the endoscope connector or the working port of the endoscope insertion part corresponds to the end of the cylinder seat facing away from the comb teeth. The brush bar of the cleaning brush passes through the water inlet or the working port and then through the threading hole. It overcomes the elastic force of the elastic band and pushes each of the comb teeth out of the cylinder seat. After the brush bar passes through each of the comb teeth, each of the comb teeth returns to its original position and gathers under the elastic force of the annular contraction of the elastic band.

[0011] In a possible implementation of the first aspect, the annular surface of one end of the cylinder seat is provided with embedded grooves in an annular pattern, and the annular surface of the cylinder seat is provided with an annular groove. The annular groove clamps the coil and passes through each of the embedded grooves. One end of the comb tooth is provided with a rotating hole, and the end of each comb tooth with the rotating hole is embedded in each of the embedded grooves in a corresponding manner. The coil is embedded in the annular groove and passes through the rotating hole of each of the comb teeth.

[0012] In one possible implementation of the first aspect, the device further includes a positioning device, the positioning device comprising: A fixing base is fixed to the placement plate, and the fixing base is located on one side of the fixing frame; A connecting seat, wherein the middle of the connecting seat is a receiving groove, both sides of the connecting seat are provided with straight grooves, and the connecting seat is provided with a first waist-shaped hole that penetrates the receiving groove and the two straight grooves; A pressure arm, comprising a connecting part and a pressing part that are perpendicular to each other, wherein the connecting part is provided with a second oblong hole; A transverse frame, wherein movable rods are provided on both sides of the transverse frame, and a transmission rod is fixed between the two movable rods; The pressing element has a triangular structure. The connecting seat, the transverse frame, and the pressure arm are mirror-arranged at both ends of the fixed base. The connecting seat is fixed to the fixed base, the connecting part is embedded in the receiving groove, and the connecting part and the connecting seat are pivotally connected. The two moving rods of the transverse frame are respectively adapted to be embedded in the two straight grooves, and the transmission rod passes through the first waist-shaped hole and the second waist-shaped hole. Two tension springs are connected between the two transverse frames. The pressing member restricts movement between the two tension springs, and the tip of the pressing member faces the fixed base. When the endoscope is placed on the placement plate, the connector and the operating handle are placed at both ends of the fixed base. When the pressing member moves into the fixed base, it drives both sides to press against the two transverse frames respectively, pushing the two transverse frames to move out of the fixed base. The transverse frames push the connecting part of the pressure arm to swing out of the fixed base, so that the pressing part of the two pressure arms presses against the connector and the operating handle respectively.

[0013] In one possible implementation of the first aspect, the positioning device further includes a first bolt threadedly inserted into the fixing seat, and the first bolt is fixed axially relative to the pressing member.

[0014] Secondly, the present invention also discloses a method for operating the above-mentioned device, the method comprising the following steps: Place the endoscope to be cleaned on the placement plate, and place the connector and operating handle of the endoscope at both ends of the fixing base. Then straighten and arrange the insertion part of the endoscope and the light guide tube neatly. The connecting piece is moved along the straight rail, and one end of the swing frame is moved, so that the other end of the swing frame swings relative to the fixed frame along the arc rail. The angle of the swing frame is adjusted so that the axis of the cleaning brush is collinear or approximately collinear with the axis of a channel hole in the endoscope operating handle. The drive motor of the threading device is started, which drives the drum to rotate. The drum drives the guide wheel connected to it to rotate synchronously and in the same direction. The guide wheel moves the filaments of the cleaning brush through friction, so that the brush bar can be smoothly inserted into the corresponding channel hole in the operating handle, and then pass through the channel section inside the operating handle and the channel section inside the insertion part in sequence, and finally out of the insertion part. During this process, the bristles on the outer periphery of the brush bar fully contact and rub against the inner wall of the channel, scraping off and carrying away the dirt attached to the inner wall of the channel. Then the drive motor reverses, driving the drum and the guide wheel to rotate in the opposite direction. The brush bar is pulled back to the initial position along the original path by the filaments. The drive motor rotates forward again, driving the guide wheel to rotate in the forward direction, pulling the filaments to move and moving the brush bar along the channel hole again. This process of controlling the drive motor to rotate forward and reverse repeatedly makes the brush bar move back and forth in the channel multiple times, completing the thorough cleaning of the channel. Drive the connector to move along the straight rail, push one end of the swing frame to move, so that the other end of the swing frame swings relative to the fixed frame along the arc rail, and adjust the angle of the swing frame until the axis of the brush bar and the axis of another channel hole in the endoscope operating handle are collinear or approximately collinear. Using the same operating method as the first channel cleaning described above, the drive motor repeatedly rotates forward and backward, driving the guide wheel to rotate repeatedly in the forward and reverse directions. With the help of the traction of the silk thread, the brush rod is driven to move back and forth in the channel, scraping and carrying away the dirt in the channel. After cleaning each channel, remove the cleaned endoscope from the placement plate.

[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: The device of the present invention drives the drum to rotate through a drive motor, and with the guide wheel guiding and limiting the wire and the friction transmission effect, it can stably pull the wire to drive the brush rod to move back and forth relative to the endoscope tubing. The swing frame, relying on the sliding cooperation of the arc groove and the arc rail and the pivot structure with the connecting parts, can achieve flexible and precise angle adjustment, thereby adapting to the channel holes with different inclinations in the endoscope operating handle, effectively avoiding the problems of interference and jamming between the brush rod and the inner wall of the channel hole during the brush rod insertion and cleaning process, ensuring that the brush rod is always accurately aligned with the channel hole entrance and smoothly inserted into the tubing to complete the cleaning action. This automated operation method is more convenient than manually inserting and removing the wire into and out of the tubing for cleaning, and can effectively improve the convenience and smoothness of the endoscope tubing cleaning operation.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings.

[0036] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0037] Furthermore, in this embodiment, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used to describe and clarify relative positions, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0038] This invention provides a device for cleaning endoscopic tubing, as shown in the attached document. Figure 1 and 2As shown, the operating handle 11 of the endoscope being cleaned by this device has multiple relatively inclined channel structures inside, such as air / water supply channels and biopsy channels. These channels are all preset functional channels of the endoscope, mainly used to realize fluid delivery inside the endoscope and insertion of biopsy instruments. In terms of connectivity, one end of each channel extends to a connection hole on the same side of the operating handle 11, used to insert biopsy instruments or connect to air or water sources through the connection hole. The other end of each channel is respectively connected to the insertion part 13 of the endoscope or to the connector 12 of the endoscope through a light guide hose 14. Finally, multiple independent and non-interfering internal channels are formed between the operating handle 11, the insertion part 13, and the connector 12. These channels are the objects to be cleaned in the cleaning operation of this invention.

[0039] As attached Figure 3 As shown, the device of the present invention includes a placement plate 2, a threading device 3, a locking device 4, and a positioning device 5. The threading device 3, the locking device 4, and the positioning device 5 are all disposed on the placement plate 2. The placement plate 2 is also used to place the endoscope. The positioning device 5 is used to fix the connector 12 and the operating handle 11 of the endoscope on the placement plate 2. The threading device 3 is used to clean the internal tubing of the endoscope.

[0040] As attached Figures 4 to 6 As shown, the positioning device 5 includes a fixed base 51, a connecting base 52, a pressure arm 53, a transverse frame 54, and a pressing member 55. The fixed base 51 is fixed to the placement plate 2 and is located on one side of the threading device 3. The connecting base 52, the transverse frame 54, and the pressure arm 53 are mirror-mounted at both ends of the fixed base 51. The connecting base 52 is fixed to the fixed base 51. (Refer to the attached diagram...) Figure 8 The connecting seat 52 has a receiving groove 521 in the middle, and straight grooves 522 on both sides. The connecting seat 52 also has a first oblong hole 523 that penetrates the receiving groove 521 and the two straight grooves 522. (See attached diagram.) Figure 7 The pressure arm 53 includes a connecting portion 531 and a pressing portion 532 that are perpendicular to each other. A second oblong hole 533 is provided at the end of the connecting portion 531. The connecting portion 531 is embedded in a receiving groove 521, and the connecting portion 531 and the connecting seat 52 are pivotally connected. The second oblong hole 533 is located at the end of the connecting portion 531 away from the pressing portion 532. (See attached diagram.) Figure 9Moving rods 541 are provided on both sides of the transverse frame 54, and a transmission rod 542 is fixed between the two moving rods 541. The two moving rods 541 are respectively fitted into two straight grooves 522, and the transmission rod 542 passes through the first oblong hole 523 and the second oblong hole 533. In this structure, the cooperation between the straight groove 522 and the first oblong hole 523 can guide the movement trajectory of the transverse frame 54 and avoid its displacement deviation. Two tension springs 56 are connected between the two transverse frames 54. The elastic force of the tension springs 56 maintains the tension that pulls the two transverse frames 54 toward the middle of the fixed seat 51, so that the transverse frame 54 maintains its initial standby position. The pressing member 55 is restricted to linear movement only relative to the fixed seat 51 between the two tension springs 56. The pressing member 55 has a triangular plate structure, and the tip of the pressing member 55 faces the fixed seat 51.

[0041] In addition, the positioning device 5 also includes a first bolt 57, which is threadedly inserted into the fixed seat 51 and is axially fixed relative to the pressing member 55. Specifically, a bearing seat is fixedly connected to the upper end of the pressing member 55, and the end of the first bolt 57 is embedded in and fixedly connected to the bearing seat. Through the assembly connection of the bearing seat, the first bolt 57 can only rotate relative to the pressing member 55 and cannot produce axial displacement. With this configuration, rotating the first bolt 57 can drive the pressing member 55 to make a smooth lifting and lowering movement along the fixed seat 51 by means of its threaded transmission with the fixed seat 51.

[0042] When placing the endoscope on the placement plate 2, first place the connector 12 and the operating handle 11 at both ends of the fixed base 51, then straighten and arrange the insertion part 13 and the light guide hose 14 so that the water inlet of the connector 12 and the port of the insertion part 13 correspond to one of the sets of locking devices 4 respectively; then move the pressing member 55 toward the middle of the fixed base 51, and simultaneously press the two transverse frames 54 on both sides of the pressing member 55, pushing the two transverse frames 54 to move horizontally toward the outside of the fixed base 51. During the movement of the transverse frames 54, the connecting part 531 of the pressure arm 53 swings to the outside of the fixed base 51, so that the pressing part 532 of the two pressure arms 53 presses the connector 12 and the operating handle 11 respectively, thereby realizing the synchronous clamping and fixing of the connector 12 and the operating handle 11. This operation process can achieve synchronous fixation of the two end components by means of the unidirectional movement of the pressing part 55, without the need to operate the two sets of positioning structures separately. This simplifies the operation steps of endoscope positioning, improves the efficiency of positioning operations, and provides a stable structural foundation for the brush rod 362 to penetrate the endoscope channel.

[0043] As attached Figures 10 to 13As shown, the threading device 3 includes a fixed frame 31, a slider 32, a connector 33, a swing frame 34, a drum 35, and a cleaning brush 36. The fixed frame 31 is fixed to the placement plate 2 and is located on one side of the fixed base 51. One end of the fixed frame 31 is provided with an arc-shaped rail 311, and the other end with a straight rail 313. Specifically, the two sides of the fixed frame 31 are support rods 312, and the ends of the arc-shaped rail 311 and the straight rail 313 are respectively fixed to the two support rods 312. This structural design allows the arc-shaped rail 311 and the straight rail 313 to maintain a stable installation posture, providing reliable structural support for the subsequent angle adjustment of the swing frame 34. The linear rail 313 can be a guide post. The slider 32 has guide holes extending through both ends, which fit around the linear rail 313 to restrict the slider 32 to slide only along the linear rail 313. One end of the connecting member 33 is provided with a sliding rod 331, which passes through the slider 32 with a clearance fit, and the sliding rod 331 is perpendicular to the linear rail 313. One end of the swing frame 34 is provided with two rotatable guide wheels 37. The other end of the fixed frame 31 and the other end of the connecting member 33 are pivotally connected. In this embodiment, the pivot connection structure can be formed by inserting a pin, allowing the two pivotally connected parts to swing relative to each other. The pin pivot connection ensures that the relative swing between the swing frame 34 and the connecting member 33 is flexible and stable, providing a smooth movement basis for angle adjustment operations.

[0044] Please refer to the appendix. Figure 14 An arc-shaped groove (not shown in the attached figure) is provided on the swing frame 34. The arc-shaped groove is fitted to the outside of the arc-shaped rail 311. After the arc-shaped groove is fitted to the outside of the arc-shaped rail 311, the swing frame 34 fixes the sealing plate 341 on the arc-shaped groove to limit the arc-shaped rail 311 to be located inside the arc-shaped groove. The addition of the sealing plate 341 can effectively prevent the arc-shaped rail 311 from detaching from the arc-shaped groove, improve the stability of the structural connection, and at the same time limit the swing frame 34 to swing only relative to the arc of the arc-shaped rail 311 at one end, ensuring that the swing trajectory of the swing frame 34 is controllable, thereby adapting to the orientation requirements of the two relatively inclined channel holes in the endoscope operating handle 11, creating conditions for the precise insertion of the brush rod 362.

[0045] Continue to refer to the appendix Figure 10The fixing frame 31 has two upright plates 314 fixed on both sides, and the support rod 312 is located between the two upright plates 314. A crossbeam 315 is fixed above the two upright plates 314. The crossbeam 315 is provided with a strip hole. The length extension direction of the strip hole is parallel to the length extension direction of the straight rail 313. The connecting piece 33 is adapted to connect the second bolt 39 with a thread. The stud of the second bolt 39 passes through the strip hole and is threadedly connected to the connecting piece 33. When adjusting the angle of the swing frame 34 relative to the fixed frame 31, the second bolt 39 can be loosened and moved along the strip hole. The second bolt 39 drives the slider 32 to move along the straight rail 313, thereby pushing one end of the swing frame 34 to move through the connector 33, so that the other end of the swing frame 34 swings relative to the fixed frame 31 along the arc rail 311. The sliding adjustment method after loosening the screw is convenient to operate. With the guidance of the straight rail 313 and the trajectory constraint of the arc rail 311, the angle of the swing frame 34 can be smoothly adjusted, which can meet the alignment requirements of the channel holes with different inclination angles relative to the connecting hole in the endoscope operating handle 11. Then, the second bolt 39 can be tightened downwards onto the crossbeam 315 to lock the swing frame 34. After tightening, the screw, with the self-locking characteristic of the thread and the pressing force of the crossbeam 315, can lock the swing frame 34 firmly at the target angle, preventing the swing frame 34 from shifting during the cleaning operation and ensuring the accuracy of the brush rod 362's insertion and reciprocating cleaning action.

[0046] The drum 35 rotates within the swing frame 34. A drive motor 38 is fixed above the swing frame 34, and the output shaft of the drive motor 38 is connected to the drum 35, causing the drive motor 38 to drive the drum 35 to rotate. One of the guide wheels 37 is connected to the drum 35, allowing the drum 35 and the guide wheel 37 to rotate synchronously and in the same direction. The filaments 361 of the cleaning brush 36 are wound inside the drum 35. The filaments 361 at the end of the cleaning brush 36 pass through the two guide wheels 37, and the brush bar 362 of the cleaning brush 36 is located between the two guide wheels 37 on the side away from the swing frame 34. Furthermore, the annular surface of the guide wheel 37 forms a recessed groove 422. The filaments 361 of the cleaning brush 36 pass through the grooves 422 of the two guide wheels 37 with an interference fit. This method can increase the frictional resistance between the guide wheel 37 and the filaments 361, so that the guide wheel 37 can stably pull the filaments 361 when rotating, effectively preventing slippage between the filaments 361 and the guide wheel 37.

[0047] During the cleaning operation, after the endoscope to be cleaned is fixed on the placement plate 2, the connection hole of the endoscope operating handle 11 is aligned with the middle of one end of the arc-shaped rail 311 of the fixing frame 31. Then, by adjusting the swing frame 34, the axis of the brush 362 of the cleaning brush 36 is made collinear or nearly collinear with the axis of one of the channel holes inside the operating handle 11, so that the brush 362 is aligned with the entrance end of the channel hole. Then, the swing frame 34 is locked and fixed. Next, the guide wheel 37 is driven to rotate forward. Through the transmission cooperation between the guide wheel 37 and the wire 361, the wire 361 is pulled to move linearly, driving the brush 362 to smoothly extend into the corresponding channel hole, passing through the internal channel section of the operating handle 11, the internal channel section of the insertion part 13, and finally out of the insertion part 13. During this process, the bristles on the outer periphery of the brush 362 fully contact and rub against the inner wall of the channel, effectively scraping away and carrying away residual mucus, tissue debris, and other contaminants from the gastroscopy examination. Then, the guide wheel 37 is driven to rotate in the opposite direction, pulling the brush 362 back to its initial position along the original path via the thread 361. The guide wheel 37 is then controlled to rotate forward again, causing the brush 362 to move back and forth along the channel. This cycle is repeated multiple times to thoroughly clean the channel. After cleaning one channel, the locking constraint of the swing frame 34 is released, and the angle of the swing frame 34 is adjusted by swinging it again, ensuring that the brush 362 is precisely aligned with the entrance end of the other channel hole. The swing frame 34 is then locked and fixed again. Using the same cleaning operation method as the first channel mentioned above, the guide wheel 37 is controlled to rotate repeatedly in the forward and reverse directions. With the traction of the silk thread 361, the brush rod 362 is driven to move back and forth in the channel, thereby scraping away and carrying out the dirt in the channel, and finally achieving a comprehensive and thorough cleaning of the two inclined channels in the endoscope operating handle 11.

[0048] In the above cleaning operation, the swing frame 34, with its angle adjustable and locking structure around the arc-shaped rail 311, can adapt to the different orientation requirements of the two relatively inclined channel holes inside the endoscope operating handle 11 after it is fixed. This ensures that the brush rod 362 is aligned with the entrance end of each channel hole at the connection hole 101 of the operating handle 11, effectively avoiding interference or jamming between the brush rod 362 and the inner wall of the channel hole during the insertion process, and ensuring the stable transmission of the traction power of the wire 361. At the same time, with the help of the forward and reverse cyclic drive of the guide wheel 37, the brush rod 362 can be automatically reciprocated in the channel for cleaning. Compared with the traditional manual cleaning method, this not only greatly improves the cleaning efficiency, but also ensures the uniformity of the cleaning force in each channel section, significantly improves the cleaning effect, reduces the risk of dirt residue, and provides a guarantee for the subsequent safe use of the endoscope.

[0049] As attached Figures 15 to 17As shown, the locking device 4 includes a base 41, comb teeth 42, elastic band 43, and coil 44. The base 41 is fixed to the placement plate 2 and has a threading hole 401 that passes through both ends of the base 41, providing a guiding channel for the passage of the cleaning brush 362. Multiple insertion slots 411 are arranged in a ring array around the axis of the threading hole at one end of the base 41. Each insertion slot 411 is fitted with a comb tooth 42, and the ring array arrangement allows each comb tooth 42 to form a uniform circumferential constraint on the brush 362. An annular groove 412 is also formed on the annular surface of the base 41, within which the coil 44 is clamped, and the annular groove 412 extends through each insertion slot 411. A recessed slot 422 is provided on one side of the comb tooth 42, and a rotating hole 421 is provided at one end of the comb tooth 42. The end of each comb tooth 42 with the rotating hole 421 is embedded into the corresponding insertion slot 411. The coil 44 passes through the rotating hole 421 of each comb tooth 42 and is embedded in the annular groove 412. Through the coordinated cooperation of the coil 44, the rotating hole 421, and the annular groove 412, each comb tooth 42 can be limited to a structure that can only swing relative to the threading hole, which not only ensures the flexibility of the comb tooth 42 swinging, but also prevents the comb tooth 42 from falling off or shifting. The elastic band 43 can be made of rubber ring, and the elastic band 43 is simultaneously wrapped around the groove 422 of each comb tooth 42 to hold each comb tooth 42 in place. The elastic pre-tightening force of the elastic band 43 shrinks in an annular shape to gather each comb tooth 42 toward the axis of the threading hole. This elastic gathering structure allows the comb tooth 42 to flexibly block the inserted brush bar 362, without generating excessive resistance to the reciprocating movement of the brush bar 362, thus ensuring the smoothness and stability of the brush bar 362's movement.

[0050] Please refer to the appendix. Figure 1After the endoscope is placed on the placement plate 2, the water inlet of the endoscope connector 12 or the working port of the endoscope insertion part 13 corresponds to the end of the cylinder base 41 facing away from the comb teeth 42. This alignment design ensures that the brush rod 362's passage path is connected to the endoscope channel, providing a stable structural foundation for subsequent dirt cleaning. Specifically, after the brush rod 362 of the cleaning brush 36 passes through the water inlet or operating port, it enters and passes through the threading hole 401, overcoming the elastic force of the elastic band 43 to push each comb tooth 42 out of the cylinder base 41. The elastic expansion and contraction performance of the elastic band 43 can adapt to the passage movement of the brush rod 362, neither causing excessive resistance to the movement of the brush rod 362 nor providing a continuous force for the comb teeth 42 to reset. After the brush rod 362 passes through each comb tooth 42, each comb tooth 42 resets and gathers under the elastic force of the annular contraction of the elastic band 43, quickly restoring the circumferential constraint state on the threading hole. When the thread 361 pulls the brush 362 back to its original position, the bristles of the brush 362 are blocked by the gathered comb teeth 42 and bend back. At the same time, the blocking effect of each comb tooth 42 can effectively trap the dirt carried out by the brush 362, thereby achieving the purpose of cleaning the brush 362. This instant cleaning structure can prevent dirt from adhering to the surface of the brush 362. In this way, each time the brush 362 moves back and forth through each comb tooth 42, the removal and trapping of dirt can be completed simultaneously, fundamentally preventing the brush 362 from bringing dirt back when it returns to the inside of the channel, significantly improving the cleanliness of the endoscope channel and reducing the risk of secondary contamination.

[0051] After leak testing, enzyme washing to disinfect surface mucus, and rinsing with enzyme disinfectant, this device achieves channel cleaning based on the two relatively inclined and independent channel hole structures within the operating handle 11 of the endoscope to be cleaned, and the connection relationship between each channel hole and the insertion part 13 and the connector 12. This is achieved through the coordinated action of the positioning device 5 to fix the endoscope, the insertion device 3 to adjust the alignment of the brush 362 and drive it to reciprocate for cleaning, and the locking device 4 to trap contaminants and prevent secondary contamination. The following details the specific working method of this device for cleaning endoscope tubing, based on the functions of each component: Place the endoscope to be cleaned on the placement plate 2, and place the connector 12 and operating handle 11 of the endoscope at both ends of the fixing base 51. Then straighten and arrange the insertion part 13 and the light guide hose 14 of the endoscope so that the water inlet of the connector 12 and the port of the insertion part 13 correspond to a set of locking devices 4. It should be noted that the insertion part 13 and the light guide hose 14 should not be bent directly. The turning parts should be placed in a curved position so that the wire 361 and the brush 362 can pass through smoothly. The pressing part 55 of the moving positioning device 5 moves toward the fixed base 51, so that the two sides of the pressing part 55 simultaneously press the two transverse frames 54, pushing the two transverse frames 54 to move outward toward the fixed base 51. During the movement of the transverse frames 54, the connecting part 531 of the pressing arm 53 swings outward toward the fixed base 51, so that the pressing part 532 of the two pressing arms 53 presses the connector 12 and the operating handle 11 respectively, realizing the synchronous clamping and fixing of the connector 12 and the operating handle 11. Loosen the second bolt 39 of the threading device 3, move the second bolt 39 along the strip hole of the crossbeam 315 to drive the connecting piece 33 to move along the straight rail 313, push one end of the swing frame 34 to move, so that the other end of the swing frame 34 swings relative to the fixed frame 31 along the arc rail 311, so that the axis of the brush rod 362 of the cleaning brush 36 is collinear or nearly collinear with the axis of one of the channel holes in the endoscope operating handle 11. Then tighten the second bolt 39 downward on the crossbeam 315 to lock and fix the swing frame 34 at the target angle. The drive motor 38 of the threading device 3 is started, which drives the drum 35 to rotate. The drum 35 drives the guide wheel 37, which is connected to it, to rotate synchronously and in the same direction. The guide wheel 37 pulls the silk thread 361 to move linearly through friction with the silk thread 361, so that the brush rod 362 can be smoothly inserted into the corresponding channel hole and pass through the internal channel section of the operating handle 11 and the internal channel section of the insertion part 13 in sequence, and finally out of the insertion part 13. During this process, the bristles on the outer periphery of the brush rod 362 fully contact and rub against the inner wall of the channel hole, scraping off and carrying away the dirt attached to the inner wall of the channel. Then, the drive motor 38 is controlled to reverse, driving the drum 35 and the guide wheel 37 to rotate in the opposite direction, and the brush rod 362 is pulled back to the initial position along the original path by the silk thread 361. The drive motor 38 is controlled to rotate forward, which drives the guide wheel 37 to rotate forward. The traction wire 361 moves and drives the brush bar 362 to move again along the channel (i.e., the channel hole, the channel section inside the operating handle to the channel section inside the insertion part). The drive motor 38 is controlled to rotate forward and backward repeatedly, so that the brush bar 362 moves back and forth in the channel multiple times to complete the thorough cleaning of the channel. During this process, the brush bar 362 passes through the wire hole of the locking device 4 and overcomes the elastic force of the elastic band 43 to push open each comb tooth 42. After the brush bar 362 passes through, the comb tooth 42 resets and gathers under the action of the elastic band 43. When the wire 361 pulls the brush bar 362 to reset, the gathered comb tooth 42 blocks the bristles and makes them bend back, while trapping dirt and preventing dirt from being carried back into the pipe with the brush bar 362. Loosen the second bolt 39 to release the locking constraint of the swing frame 34, move the second bolt 39 again to drive the connecting piece 33 to move along the straight rail 313, push one end of the swing frame 34 to move so that the other end of the swing frame 34 swings relative to the fixed frame 31 along the arc rail 311, adjust the angle of the swing frame 34 until the axis of the brush rod 362 is collinear or nearly collinear with the axis of another channel hole in the endoscope operating handle 11, and then tighten the second bolt 39 downwards onto the crossbeam 315 to lock and fix the swing frame 34. Using the same operating method as cleaning the first channel, the drive motor 38 is controlled to repeatedly rotate forward and reverse, driving the guide wheel 37 to rotate repeatedly in the forward and reverse directions. With the traction of the wire 361, the brush bar 362 is driven to move back and forth in the other channel, scraping away and carrying out the dirt in the channel. The same brush bar 362 repeatedly passes through the thread hole of the blocking device 4, and each comb tooth 42 can trap the dirt on the brush bar 362, preventing the dirt from being carried back into the pipe with the brush bar 362. After cleaning the second channel, loosen the second bolt 39 to release the lock of the swing frame 34, loosen the first bolt 57 to release the clamping on the connector 12 and the operating handle 11, and remove the cleaned endoscope from the placement plate 2.

[0052] It is worth mentioning that after the endoscope is fixed on the placement plate 2, the entire placement plate 2 can be placed into the water tank. At the same time, the connection hole of the operating handle 11 is aligned with the water outlet of the faucet. This allows the flowing clean water to simultaneously rinse and clean the reciprocating filaments 361 and the brush rod 362 during the cleaning operation. Meanwhile, the clean water can flow into the endoscope tube, forming a synergistic effect with the friction cleaning of the brush rod 362, thus helping to improve the cleanliness of the inner wall of the tube.

[0053] The above method first involves properly positioning the endoscope and securing the connector 12 and operating handle 11 using the positioning device 5. Then, the angle of the swing frame 34 of the insertion device 3 is adjusted to precisely align and lock the brush rod 362 within the channel hole. The brush rod 362 is then driven to reciprocate and clean within the channel section, while the retaining device 4 traps contaminants to prevent secondary contamination. After cleaning one channel, the process is repeated to clean the other channel. Finally, the endoscope is released and removed. This method, through the coordinated operation of various devices, simplifies the operation process and ensures stability during cleaning.

[0054] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using the concept of the present invention shall constitute an infringement of the protection scope of the present invention.

A method of operating the device as described in any one of claims 1 to 9, characterized in that, The method includes the following steps: Place the endoscope to be cleaned on the placement plate, and place the connector and operating handle of the endoscope at both ends of the fixing base. Then straighten and arrange the insertion part of the endoscope and the light guide tube neatly. The connecting piece is moved along the straight rail, and one end of the swing frame is moved, so that the other end of the swing frame swings relative to the fixed frame along the arc rail. The angle of the swing frame is adjusted so that the axis of the cleaning brush is collinear or approximately collinear with the axis of a channel hole in the endoscope operating handle. The drive motor of the threading device is started, which drives the drum to rotate. The drum drives the guide wheel connected to it to rotate synchronously and in the same direction. The guide wheel moves the filaments of the cleaning brush through friction, so that the brush bar can be smoothly inserted into the corresponding channel hole in the operating handle, and then pass through the channel section inside the operating handle and the channel section inside the insertion part in sequence, and finally out of the insertion part. During this process, the bristles on the outer periphery of the brush bar fully contact and rub against the inner wall of the channel, scraping off and carrying away the dirt attached to the inner wall of the channel. Then the drive motor reverses, driving the drum and the guide wheel to rotate in the opposite direction. The brush bar is pulled back to the initial position along the original path by the filaments. The drive motor rotates forward again, driving the guide wheel to rotate in the forward direction, pulling the filaments to move and moving the brush bar along the channel hole again. This process of controlling the drive motor to rotate forward and reverse repeatedly makes the brush bar move back and forth in the channel multiple times, completing the thorough cleaning of the channel. Drive the connector to move along the straight rail, push one end of the swing frame to move, so that the other end of the swing frame swings relative to the fixed frame along the arc rail, and adjust the angle of the swing frame until the axis of the brush bar and the axis of another channel hole in the endoscope operating handle are collinear or approximately collinear.

With the help of the traction of the silk thread, the brush rod is driven to move back and forth in the channel, scraping and carrying away the dirt in the channel. After cleaning each channel, remove the cleaned endoscope from the placement plate.
