Description

Technical Field

[0001] The present invention relates to the technical field of endoscopic lumen cleaning, and specifically to a device and method for synchronously cleaning the inner and outer walls of endoscopic lumen instruments. Background Art

[0002] After endoscopic surgery, a large amount of organic matter, such as blood, mucus, and secretions, will adhere to the instruments. The coagulation of organic matter contamination will rust and corrode the instruments, causing premature scrapping of the instruments and increasing the hospital costs. Moreover, the organic matter contamination contains a large number of pathogens and pyrogens. If the instruments are not cleaned thoroughly, the residues will lead to sterilization failure, directly affecting the health and even the life safety of patients.

[0003] Therefore, ensuring the cleaning and disinfection quality of endoscopic instruments can not only reduce instrument rust and extend the instrument life, but also be a prerequisite for successful sterilization and an important link in controlling hospital infections.

[0004] When cleaning the inner wall of the endoscopic lumen, it is usually processed by inserting a brush into the lumen and rotating and rubbing it. However, as the brushing progresses, the amount of impurities remaining on the surface of the brush will increase, resulting in a decrease in the frictional force of the brush on the inner wall of the lumen, and the brushing effect will also decline, leading to the problem of insufficient brushing of the inner wall of the lumen. Summary of the Invention

[0005] The purpose of the present invention is to provide a device and method for synchronously cleaning the inner and outer walls of endoscopic lumen instruments to solve the problems raised in the above background art.

[0008] As a further solution of the present invention: The rotating assembly includes a motor fixedly installed on the bearing plate. A transmission rod connected to the output shaft of the motor is rotatably installed on the bearing plate. The transmission rod is hollow and penetrates through the upper cross plate. A first rotating rod penetrating through the movable plate is slidably installed in the transmission rod, and a first gear is fixed on the first rotating rod.

[0009] As a further solution of the present invention: The rotary cleaning mechanism includes a plurality of second rotating rods rotatably installed on the movable plate and evenly distributed at equal intervals in a circumferential manner. A second gear meshing with the first gear is fixed at the end of the second rotating rod. A plurality of water outlet holes evenly distributed are arranged on the circumferential outer wall of the second rotating rod, and a driven assembly is arranged on the second rotating rod.

[0010] As a further solution of the present invention: The driven assembly includes a rotating sleeve slidably installed on the second rotating rod. A connecting rod is hinged on the rotating sleeve, and the connecting rod is hinged to the cleaning brush; It also includes a first hinged rod and a second hinged rod hinged on the second rotating rod, and the first hinged rod and the second hinged rod are hinged to the cleaning brush.

[0011] As a further solution of the present invention: The follow-up telescopic mechanism includes a guide post fixedly installed on the movable plate. A support sleeve is slidably installed on the guide post. A follow-up plate rotatably connected to the rotating sleeve is fixed on the support sleeve, and an elastic component connected to the second rotating rod is arranged on the guide post.

[0012] As a further solution of the present invention: The elastic component includes a guide groove opened on the circumferential outer wall of the second rotating rod. A movable ring is fixed at the end of the support sleeve. A first limiting post slidably connected to the guide groove is fixed on the movable ring, and a spring abutting against the movable ring is sleeved on the guide post.

[0013] As a further solution of the present invention: The gradient regulation mechanism includes a connecting plate slidably installed on the support sleeve. A limiting ring sleeved on the second rotating rod is fixed on the connecting plate. The limiting ring is in interference fit with the first limiting post. A second limiting post is also fixed on the connecting plate, and a guiding component connected to the second limiting post is arranged on the first rotating rod.

[0014] As a further solution of the present invention: the guide assembly includes a rotating disk fixedly installed on the end of the first rotating rod, and the circumferential outer wall of the rotating disk is provided with an upper ring groove, an inclined groove, and a lower ring groove that are symmetrically arranged, and the second limiting column can slide along the upper ring groove, the inclined groove, and the lower ring groove.

[0015] A method for synchronously cleaning the inner and outer walls of a laparoscope lumen instrument comprises the following steps: Step 1: Place the lumen instrument to be cleaned in the first tank, and wash the instrument with enzyme solution according to the proportion; Step 2: After the enzyme washing is completed, the lumen instrument is moved to the second tank body for ultrasonic cleaning; Step 3: After the ultrasonic cleaning is completed, the tubular cavity device is moved to the third tank body, and the cleaning brush is controlled to be inserted into the tubular cavity device. Under the action of the driving mechanism, the cleaning brush is controlled to rotate by the rotating cleaning mechanism while moving along the length direction of the tubular cavity device; Step 4: At the same time, when the follow-up telescopic mechanism and the gradual control mechanism cooperate, the cleaning brush moves towards or away from the inner wall of the tubular cavity device to perform a brushing action on the inner wall of the tubular cavity device. After brushing, the residual water on the inner and outer walls of the tubular cavity device is blown away by a high-pressure air gun.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the present application can quickly process the impurities brushed out by adjusting the coordination state between the cleaning brush and the inner wall of the lumen to ensure the best cleaning effect of the inner wall of the lumen. Specifically, after the laparoscope lumen passes through the enzyme water washing and ultrasonic cleaning in the first tank body and the second tank body, it can be transferred to the third tank body, and under the action of the driving mechanism and the rotating cleaning mechanism, the cleaning brush is controlled to be inserted into the lumen while performing a rotating cleaning action, and under the action of the follow-up telescopic mechanism and the gradual control mechanism, the distance between the cleaning brush and the inner wall of the lumen is continuously adjusted to realize the reciprocating intermittent brushing of the inner wall of the lumen by the cleaning brush.

[0017] By controlling the cleaning brush to reciprocately fit and separate from the inner wall of the tube cavity, the cleaning brush can first loosen the impurities remaining on the inner wall of the tube cavity by scrubbing, and when the cleaning brush separates from the inner wall of the tube cavity, the impurities are controlled to leave the tube cavity through water impact. At the same time, the surface of the cleaning brush can also be rinsed, which can achieve the effect of changing the friction of the cleaning brush on the inner wall of the tube cavity by reciprocating scrubbing and enhancing the cleaning effect of the inner wall of the tube cavity, and prevent the problem of too much impurities remaining on the cleaning brush due to the cleaning brush always being in contact with the inner wall of the tube cavity, resulting in a decrease in the scrubbing force of the cleaning brush.

[0018] When the distance between the two cleaning brushes changes, according to the parallelogram law, the two cleaning brushes will also have a certain displacement in the vertical direction. Therefore, while the cleaning brushes provide rotational frictional force to the inner wall of the lumen, they can also provide frictional force in the vertical direction to ensure the best cleaning effect on the inner wall of the lumen.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0032] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a device for synchronously cleaning the inner and outer walls of a laparoscopic lumen instrument includes: A cleaning pool 1, and a first pool body 101, a second pool body 102, and a third pool body 103 formed on the cleaning pool 1. A support plate 2 is fixed on the cleaning pool 1, and an upper cross plate 3 and a lower cross plate 4 are fixed on the support plate 2; It further includes: A driving mechanism is disposed on the upper cross plate 3. A rotary cleaning mechanism is disposed on the driving mechanism. Symmetrically arranged cleaning brushes 20 are connected to the rotary cleaning mechanism. The driving mechanism can drive the cleaning brushes 20 to rotate and move in the vertical direction through the rotary cleaning mechanism; A follow-up telescopic mechanism is arranged on the driving mechanism and connected to the rotary cleaning mechanism. When the driving mechanism moves, the follow-up telescopic mechanism can control the cleaning brush 20 to move in a direction approaching or separating from each other through the rotary cleaning mechanism; A gradient regulation mechanism is arranged on the driving mechanism and cooperates with the follow-up telescopic mechanism. The gradient regulation mechanism can adjust the telescopic distance of the cleaning brush 20 through the follow-up telescopic mechanism.

[0033] Specifically, four through holes are formed in the lower cross plate 4 and are equally distributed in a circumferential manner. A plurality of groups of clamping members are rotatably installed on the lower cross plate 4. Each group of clamping members is composed of clamping plates 5 arranged symmetrically. A torsion spring is sleeved on the rotating shaft of the clamping plate 5. Under the action of the torsion spring, the two clamping plates 5 are in mutual contact. After the endoscopic lumen is subjected to enzymatic water washing and ultrasonic cleaning through the first pool 101 and the second pool 102, the washed endoscopic lumen can be moved into the third pool 103, and the endoscopic lumen is clamped by the clamping plates 5. At this time, under the action of the driving mechanism, the cleaning brush 20 is controlled to enter the endoscopic lumen through the rotary cleaning mechanism. The driving mechanism can also control the cleaning brush 20 to rotate through the rotary cleaning mechanism. And under the action of the follow-up telescopic mechanism and the gradient regulation mechanism, the cleaning brush 20 moves in a direction approaching or separating from the inner wall of the endoscopic lumen to brush the inner wall of the endoscopic lumen. When the cleaning brush 20 is separated from the inner wall of the lumen, through the flushing method, the impurities brushed out are quickly separated from the lumen until the cleaning brush 20 fully brushes the entire inner wall of the lumen. By controlling the intermittent contact brushing between the cleaning brush 20 and the inner wall of the lumen, it is possible to brush the inner wall of the lumen while ensuring that there are no impurities remaining on the inner wall of the lumen through the impact of water flow, so as to ensure the best brushing effect on the inner wall of the lumen.

[0034] Please refer to Figures 1 - 3 、 Figure 5 、 Figure 9 As shown in, the driving mechanism includes a cylinder 6 and a receiving plate 8 fixedly installed on the upper cross plate 3. A movable plate 7 is fixed on the telescopic end of the cylinder 6. A rotating assembly connected to the movable plate 7 is arranged on the receiving plate 8. Among them, the rotating assembly includes a motor 9 fixedly installed on the receiving plate 8. A transmission rod 10 connected to the output shaft of the motor 9 is rotatably installed on the receiving plate 8. The transmission rod 10 is hollow and penetrates through the upper cross plate 3. A first rotating rod 11 penetrating through the movable plate 7 is slidably installed in the transmission rod 10. A first gear 12 is fixed on the first rotating rod 11.

[0035] Specifically, when cleaning the lumen of the endoscope, it is necessary to ensure that there is no residue of impurities in the lumen of the endoscope through multi-stage cleaning to avoid the problem of patient infection caused by impurities in subsequent surgeries. The first tank body 101 is used for enzymatic water washing, and the second tank body 102 is used for ultrasonic cleaning. In the initial state, under the action of the cylinder 6, the distance between the movable plate 7 and the lower cross plate 4 is the largest, and the size of the engagement between the transmission rod 10 and the first rotating rod 11 is the largest. Specifically, pure water is added to the first tank body 101, and a cleaning enzyme is added according to the required ratio. At this time, the lumen of the endoscope to be cleaned can be added to the first tank body 101, and the outer wall of the lumen can be cleaned through the cooperation of the gauze. After the enzymatic water washing is completed, the lumen of the endoscope can be transferred to the second tank body 102 for ultrasonic cleaning. After the cleaning is completed, the lumen of the endoscope is transferred to the third tank body 103, and the lumen of the endoscope is clamped by the clamping plate 5. At this time, under the action of the cylinder 6, the movable plate 7 is controlled to move towards the lower cross plate 4, so that the cleaning brush 20 enters the lumen through the movement of the rotary cleaning mechanism. At this time, the motor 9 works and drives the transmission rod 10 to rotate, thereby driving the first rotating rod 11 to rotate. The first rotating rod 11 will control the movement of the rotary cleaning mechanism through the first gear 12 to drive the cleaning brush 20 to rotate along the central axis of the lumen. The cylinder 6 continues to move, so that the cleaning brush 20 rotates and moves along the length direction of the lumen to ensure a comprehensive cleaning of the lumen.

[0036] Preferably, through the cooperation of the first gear 12 and the rotary cleaning mechanism, four cleaning brushes 20 can synchronously clean the inner walls of four endoscope lumens, and by controlling the rotation and movement of the cleaning brushes 20, the effect of mimicking manual brushing can be achieved to ensure that the entire inner wall of the lumen can be brushed.

[0037] Please refer to Figures 1 - 3 、 Figures 5 - 7 As shown in, the rotary cleaning mechanism includes a plurality of second rotating rods 14 rotatably installed on the movable plate 7 and distributed at equal intervals in a circumferential manner. A second gear 15 meshing with the first gear 12 is fixed at the end of the second rotating rod 14. A plurality of water outlet holes 1404 are arranged at equal intervals on the circumferential outer wall of the second rotating rod 14. A driven assembly is arranged on the second rotating rod 14. Among them, the driven assembly includes a rotating sleeve 16 slidably installed on the second rotating rod 14. A connecting rod 17 is hinged on the rotating sleeve 16, and the connecting rod 17 is hinged to the cleaning brush 20; it also includes a first hinge rod 18 and a second hinge rod 19 hinged on the second rotating rod 14, and the first hinge rod 18 and the second hinge rod 19 are hinged to the cleaning brush 20.

[0038] It should be noted that the second rotating rod 14 is hollow and can be connected to a water supply pipe to convey water into the second rotating rod 14. A water supply pipe is also provided on the movable plate 7, and the water supply direction is towards the cleaning brush 20. The first hinge rod 18 and the second hinge rod 19 are parallel and equal. According to the parallelogram law, when the distance between the two cleaning brushes 20 changes, the cleaning brush 20 and the second rotating rod 14 can always maintain a parallel state. In the initial state, under the action of the follow-up telescopic mechanism, the rotating sleeve 16 is located at the end of the stroke towards the movable plate 7. At this time, the included angle between the connecting rod 17 and the second rotating rod 14 is the smallest, making the distance between the two cleaning brushes 20 the smallest. The distance between the two cleaning brushes 20 is smaller than the inner diameter of the endoscopic lumen. Therefore, the cleaning brush 20 can be smoothly inserted into the lumen. When the endoscopic lumen is clamped, under the action of the cylinder 6, the movable plate 7 is pushed to move, thereby controlling the cleaning brush 20 to move towards the lumen. When the side of the cleaning brush 20 away from the movable plate 7 enters the lumen, at this time, water can be sent into the second rotating rod 14 and the lumen through the water supply pipe. The water in the second rotating rod 14 will be discharged through the water outlet holes 1404 and impact on the inner wall of the lumen. The flowing water in the lumen can play a certain flushing effect. At the same time, the motor 9 works, drives the first gear 12 to rotate through the transmission rod 10 and the first rotating rod 11, thereby driving the second gear 15 to rotate, making the second rotating rod 14 rotate. The second rotating rod 14 will control the cleaning brush 20 to move around the second rotating rod 14 through the first hinge rod 18 and the second hinge rod 19. At the same time, under the action of the follow-up telescopic mechanism, the rotating sleeve 16 is driven to move away from the movable plate 7, thereby controlling the two cleaning brushes 20 to move away from each other through the connecting rod 17, so that the bristles of the cleaning brush 20 are attached to the inner wall of the lumen, and under the action of friction, the impurities remaining on the inner wall of the lumen are brushed. When the distance between the two cleaning brushes 20 reaches the maximum, the follow-up telescopic mechanism can also control the rotating sleeve 16 to move towards the movable plate 7 to control the distance between the two cleaning brushes 20 to decrease, and repeat the above steps to achieve the effect of intermittently brushing the inner wall of the lumen.

[0039] Preferably, by controlling the reciprocating contact and separation of the cleaning brush 20 with the inner wall of the lumen, the cleaning brush 20 can first brush and loosen the impurities remaining on the inner wall of the lumen. When the cleaning brush 20 separates from the inner wall of the lumen, through the impact of water flow, the impurities are controlled to break away from the lumen. At the same time, the surface of the cleaning brush 20 can also be rinsed. This can not only achieve the reciprocating brushing to change the friction force of the cleaning brush 20 on the inner wall of the lumen and enhance the cleaning effect on the inner wall of the lumen, but also prevent the problem that due to the cleaning brush 20 always being in contact with the inner wall of the lumen, too many impurities remain on the cleaning brush 20, resulting in a decrease in the brushing force of the cleaning brush 20. Among them, when cleaning the inner wall of the endoscope lumen, the outer wall of the lumen can also be synchronously cleaned through the first pool body 101 and the second pool body 102 to achieve the effect of continuous cleaning of the endoscope lumen.

[0040] Please refer to Figures 1 - 8 、 Figure 10 As shown in FIGS.

[0041] Furthermore, the guiding groove can be divided into three sections, namely the arc groove 1401, the spiral groove 1402, and the allowance groove 1403. The two ends of the spiral groove 1402 are respectively connected to the ends of the arc groove 1401 and the allowance groove 1403. In the initial state, the first limiting post 23 is located in the arc groove 1401, making the distance between the movable ring 22 and the movable plate 7 the smallest. Under the action of the movable ring 22, the distance between the rotating sleeve 16 and the movable plate 7 is controlled to be the smallest through the support sleeve 25 and the follower plate 29, so as to control the distance between the two cleaning brushes 20 to be the smallest through the connecting rod 17. At this time, the spring 24 is in a compressed state. When the second rotating rod 14 rotates, the first limiting post 23 will slide along the arc groove 1401. When the first limiting post 23 disengages from the arc groove 1401 and enters one of the spiral grooves 1402, the spring 24 elastically releases and drives the movable ring 22 to move away from the movable plate 7, so as to drive the support sleeve 25 to move. The support sleeve 25 will control the movement of the rotating sleeve 16 through the follower plate 29, so as to control the two cleaning brushes 20 to move away from each other through the connecting rod 17. The bristles of the cleaning brushes 20 will gradually fit with the inner wall of the lumen, and the scrubbing force on the inner wall of the lumen will gradually increase. When the first limiting post 23 disengages from the spiral groove 1402 and enters the end of the allowance groove 1403, the distance between the cleaning brushes 20 is the largest. When the first limiting post 23 disengages from the allowance groove 1403 and enters the other spiral groove 1402, the movable ring 22 moves towards the initial position, and the two cleaning brushes 20 move towards each other until the first limiting post 23 returns to the arc groove 1401, repeating the above steps, thereby realizing the scrubbing of the inner wall of the lumen.

[0042] Preferably, when the rotating sleeve 16 reciprocates along the length direction of the second rotating rod 14, the connecting rod 17 can adjust the distance between the two cleaning brushes 20. According to the parallelogram law, when the distance between the two cleaning brushes 20 changes, there will also be a certain displacement in the vertical direction. Therefore, while the cleaning brushes 20 provide rotational friction force to the inner wall of the lumen, they can also provide friction force in the vertical direction to ensure the best cleaning effect on the inner wall of the lumen.

[0043] Please refer to Figures 1 - 7 、 Figure 9 、 Figure 10, the gradual change control mechanism includes a connecting plate 26 slidably mounted on the support sleeve 25. A limiting ring 28 sleeved on the second rotating rod 14 is fixed on the connecting plate 26. The limiting ring 28 is in contact and cooperation with the first limiting post 23. A second limiting post 27 is also fixed on the connecting plate 26. A guiding component connected to the second limiting post 27 is arranged on the first rotating rod 11. Among them, the guiding component includes a rotating disc 13 fixedly installed at the end of the first rotating rod 11. Symmetrically arranged upper ring grooves 1301, inclined grooves 1302, and lower ring grooves 1303 are formed on the circumferential outer wall of the rotating disc 13. The second limiting post 27 can slide along the upper ring groove 1301, the inclined groove 1302, and the lower ring groove 1303.

[0044] Furthermore, there are four second rotating rods 14. Taking one of the second rotating rods 14 as an example, in the initial state, the first limiting post 23 is located in the arc groove 1401, so that the distance between the two cleaning brushes 20 is the smallest. The second limiting post 27 is located in the upper ring groove 1301 to control the limiting ring 28 to be at the end of the stroke towards the movable plate 7 through the connecting plate 26. At this time, under the action of the limiting ring 28, the conduction amount of the surplus groove 1403 is the smallest. When the first limiting post 23 moves into the surplus groove 1403, it will abut against the limiting ring 28, making the displacement of the movable ring 22 along the length direction of the guiding post 21 smaller. Therefore, the unfolded distance between the two cleaning brushes 20 is also smaller. Since the first rotating rod 11 will also drive the rotating disc 13 to rotate, the second limiting post 27 will slide along the upper ring groove 1301. When the second limiting post 27 disengages from the upper ring groove 1301 and enters the inclined groove 1302, the limiting ring 28 is controlled by the connecting plate 26 to move away from the movable plate 7, increasing the conduction amount of the surplus groove 1403. Therefore, the displacement of the movable ring 22 also increases, increasing the unfolded distance between the two cleaning brushes 20 and increasing the cleaning force of the cleaning brushes 20 on the inner wall of the lumen. When the second limiting post 27 disengages from the inclined groove 1302 and enters the lower ring groove 1303, the limiting ring 28 no longer cooperates with the second limiting post 27, and the surplus groove 1403 is completely conducted, and the unfolded distance between the two cleaning brushes 20 reaches the maximum.

[0045] Preferably, when the second limiting post 27 slides along the upper ring groove 1301, the inclined groove 1302, and the lower ring groove 1303, the maximum unfolded distance of the cleaning brush 20 will be synchronously adjusted, thereby adjusting the brushing force on the inner wall of the lumen. When the distance between the cleaning brush 20 and the inner wall of the lumen changes, the frictional force will be continuously changed to realize the brushing action on the impurities remaining on the inner wall of the lumen by means of different frictional forces acting on the inner wall of the lumen, further enhancing the brushing effect on the impurities. Among them, after the brushing is completed, the water remaining on the inner and outer walls of the endoscope lumen can be blown dry by an air gun and then disinfected by ultraviolet rays and packed.

[0046] A method for synchronously cleaning the inner and outer walls of a laparoscopic lumen instrument, comprising the following steps: Step 1: Place the lumen instrument to be cleaned in the first tank 101, and prepare an enzyme solution according to a ratio to perform enzymatic water washing on the instrument; Step 2: After the enzymatic water washing is completed, move the lumen instrument to the second tank 102 for ultrasonic cleaning; Step 3: After the ultrasonic cleaning is completed, move the lumen instrument to the third tank 103, and control the cleaning brush 20 to insert into the inside of the lumen instrument. Under the action of the driving mechanism, while controlling the cleaning brush 20 to rotate through the rotating cleaning mechanism, move along the length direction of the lumen instrument; Step 4: At the same time, when the follow-up telescopic mechanism and the gradient regulation mechanism cooperate, make the cleaning brush 20 move in the direction of approaching or departing from the inner wall of the lumen instrument to perform a brushing action on the inner wall of the lumen instrument. After the brushing is completed, blow the remaining water on the inner and outer walls of the lumen instrument clean with a high-pressure air gun.
