Description

Technical Field

[0001] The present invention relates to the technical field of laparoscope lumen cleaning, and in particular to a device and method for synchronously cleaning the inner and outer walls of a laparoscope lumen instrument. Background Art

[0002] After laparoscopic surgery, instruments are left with a large amount of organic matter, including blood, mucus, and secretions. This organic matter solidifies, rusting and corroding the instruments, causing them to prematurely fail and increasing hospital costs. Furthermore, organic matter contamination can contain numerous pathogens and pyrogens. If instruments are not properly cleaned, residue can lead to sterilization failure, directly impacting patient health and even life.

[0003] Therefore, ensuring the quality of cleaning and disinfection of laparoscopic instruments can not only reduce instrument corrosion and extend the life of the instruments, but is also a prerequisite for successful sterilization and an important part of controlling hospital infections.

[0004] When cleaning the inner wall of the laparoscope lumen, a brush is usually inserted into the lumen to perform a rotating friction scrubbing process. However, as the scrubbing progresses, the amount of impurities remaining on the brush surface will increase, resulting in a decrease in the friction of the brush on the inner wall of the lumen, and the scrubbing effect will also decrease, leading to insufficient scrubbing of the inner wall of the lumen.

[0022] A method for synchronously cleaning the inner and outer walls of a laparoscope lumen instrument comprises the following steps:

[0023] Step 1: Place the lumen instrument to be cleaned in the first tank, and prepare enzyme solution according to the proportion to perform enzyme water washing on the instrument;

[0024] Step 2: After the enzyme washing is completed, the lumen instrument is moved to the second tank body for ultrasonic cleaning;

[0025] Step 3: After the ultrasonic cleaning is completed, the tubular device is moved to the third tank body, and the cleaning brush is controlled to be inserted into the tubular device. Under the action of the driving mechanism, the cleaning brush is controlled to rotate by the rotary cleaning mechanism while moving along the length direction of the tubular device;

[0026] 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 device to perform a brushing action on the inner wall of the tubular device.

[0028] By controlling the reciprocating contact and separation of the cleaning brush with the inner wall of the tube cavity, the cleaning brush can first scrub the impurities remaining on the inner wall of the tube cavity to loosen them, 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, thereby enhancing the cleaning effect of the inner wall of the tube cavity, and prevent the problem of excessive 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.

[0029] When the distance between the two cleaning brushes changes, according to the parallelogram law, the two cleaning brushes will also undergo a certain displacement in the vertical direction. Therefore, while providing rotational friction to the inner wall of the lumen, the cleaning brushes can also provide friction in the vertical direction to ensure the best cleaning effect on the inner wall of the lumen.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0043] See also Figures 1 to 10 In an embodiment of the present invention, a device for synchronously cleaning the inner and outer walls of a laparoscope lumen instrument comprises:

[0044] A cleaning tank 1, and a first tank body 101, a second tank body 102, and a third tank body 103 formed on the cleaning tank 1. A support plate 2 is fixed to the cleaning tank 1, and an upper horizontal plate 3 and a lower horizontal plate 4 are fixed to the support plate 2;

[0045] Also includes:

[0046] A driving mechanism is provided on the upper horizontal plate 3, the driving mechanism being provided with a rotary cleaning mechanism, the rotary cleaning mechanism being connected to a symmetrically arranged cleaning brush 20, the driving mechanism being capable of driving the cleaning brush 20 to rotate through the rotary cleaning mechanism while moving in a vertical direction;

[0047] A follow-up telescopic mechanism is provided on the driving mechanism and connected to the rotating cleaning mechanism. When the driving mechanism moves, the follow-up telescopic mechanism can control the cleaning brushes 20 to move toward or away from each other through the rotating cleaning mechanism;

[0048] The gradual change regulating mechanism is provided on the driving mechanism and cooperates with the follow-up telescopic mechanism. The gradual change regulating mechanism can adjust the telescopic distance of the cleaning brush 20 through the follow-up telescopic mechanism.

[0049] Specifically, four through holes are provided on the lower cross plate 4 and are equidistantly distributed around the circumference. A plurality of groups of clamping members are rotatably installed on the lower cross plate 4. Each group of clamping members is composed of a symmetrically arranged clamping plate 5. 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 brought into contact with each other. After the laparoscope lumen passes through the first cell body 101 and the second cell body 102 for enzyme water washing and ultrasonic cleaning, the cleaned laparoscope lumen can be moved to the third cell body 103 and clamped by the clamping plate 5. At this time, under the action of the driving mechanism, the cleaning brush 20 is controlled to enter the laparoscope lumen by the rotating cleaning mechanism to drive the cleaning brush 20 into the laparoscope lumen. The dynamic mechanism can also control the rotation of the cleaning brush 20 through the rotating cleaning mechanism, and under the action of the follow-up telescopic mechanism and the gradual control mechanism, the cleaning brush 20 moves toward or away from the inner wall of the laparoscope lumen to brush the inner wall of the laparoscope lumen. When the cleaning brush 20 is separated from the inner wall of the lumen, the impurities brushed out are quickly separated from the lumen by flushing until the cleaning brush 20 fully brushes the entire inner wall of the lumen. By controlling the intermittent contact and 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 no impurities remain on the inner wall of the lumen through water impact, thereby ensuring the best brushing effect of the inner wall of the lumen.

[0050] See also Figure 1-Figure 3 、 Figure 5 、 Figure 9The driving mechanism includes a cylinder 6 and a receiving plate 8 fixedly mounted on the upper horizontal plate 3, a movable plate 7 is fixed on the telescopic end of the cylinder 6, and a rotating assembly connected to the movable plate 7 is provided on the receiving plate 8, wherein the rotating assembly includes a motor 9 fixedly mounted on the receiving plate 8, and a transmission rod 10 connected to the output shaft of the motor 9 is rotatably mounted on the receiving plate 8, the transmission rod 10 is hollow and passes through the upper horizontal plate 3, and a first rotating rod 11 passing through the movable plate 7 is slidably installed in the transmission rod 10, and a first gear 12 is fixed on the first rotating rod 11.

[0051] In detail, when cleaning the laparoscope lumen, it is necessary to ensure that no impurities remain in the laparoscope lumen through multi-stage cleaning to avoid the problem of patient infection caused by impurities in subsequent operations. The first pool body 101 is used for enzyme water washing, and the second pool 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 horizontal plate 4 is maximized, and the size of the mutual fit between the transmission rod 10 and the first rotating rod 11 is maximized. Specifically, pure water is added to the first pool body 101, and cleaning enzymes are added according to the required proportion. At this time, the laparoscope lumen to be cleaned can be added to the first pool body 101, and the outer wall of the lumen can be cleaned with the cooperation of gauze. After the enzyme water washing is completed, the laparoscope lumen can be transferred to The cleaning brush 20 is moved into the second tank body 102 and ultrasonic cleaning is performed. After the cleaning is completed, the laparoscope lumen is transferred to the third tank body 103 and the laparoscope lumen 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 toward the lower horizontal plate 4, thereby rotating the cleaning mechanism to make the cleaning brush 20 enter the lumen. 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 rotating 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 moves along the length direction of the lumen while rotating to ensure comprehensive cleaning of the lumen.

[0052] Preferably, through the cooperation of the first gear 12 and the rotating cleaning mechanism, four groups of cleaning brushes 20 can be used to clean the inner walls of the four laparoscope lumens synchronously, and by controlling the rotation and movement of the cleaning brushes 20, the effect of imitating manual brushing can be achieved, ensuring that the entire inner wall of the lumen can be brushed.

[0053] See also Figure 1-Figure 3 、 Figure 5-Figure 7The rotary cleaning mechanism includes a plurality of second rotating rods 14 rotatably mounted on the movable plate 7 and circumferentially equidistantly distributed, a second gear 15 meshing with the first gear 12 being fixed to the end of the second rotating rod 14, a plurality of water outlet holes 1404 equidistantly distributed are opened on the circumferential outer wall of the second rotating rod 14, and a driven assembly is provided on the second rotating rod 14, wherein the driven assembly includes a rotating sleeve 16 slidably mounted 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 hinged rod 18 and a second hinged rod 19 hinged on the second rotating rod 14, and the first hinged rod 18 and the second hinged rod 19 are hinged to the cleaning brush 20.

[0054] It should be noted that the second rotating rod 14 is hollow and can be connected to a water supply pipe to deliver water to the second rotating rod 14. A water supply pipe is also provided on the movable plate 7, and the water supply direction is toward the cleaning brush 20. The first hinged rod 18 and the second hinged rod 19 are parallel and equally arranged. 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 always remain parallel. In the initial state, under the action of the follow-up telescopic mechanism, the rotating sleeve 16 is located toward the movable plate 7 direction of travel end, at this time, the angle between the connecting rod 17 and the second rotating rod 14 is the smallest, so that the distance between the two cleaning brushes 20 is the smallest, and the distance between the two cleaning brushes 20 is smaller than the inner diameter of the laparoscope lumen. Therefore, the cleaning brush 20 can be smoothly inserted into the lumen. When the laparoscope lumen is clamped, the movable plate 7 is pushed to move under the action of the cylinder 6, thereby controlling the cleaning brush 20 to move toward the lumen. When the cleaning brush 20 is away from one side of the movable plate 7 and enters the lumen, water can be supplied to 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 1404 and impact the inner wall of the tube cavity. The water flowing in the tube cavity can play a certain flushing effect. At the same time, the motor 9 works and 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, so that the second rotating rod 14 rotates. 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 It moves in the direction away from the movable plate 7, thereby controlling the two cleaning brushes 20 to move in the directions away from each other through the connecting rod 17, so that the bristles of the cleaning brushes 20 fit into 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 toward 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.

[0055] Preferably, by controlling the cleaning brush 20 to reciprocately fit and separate from 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, and when the cleaning brush 20 separates from the inner wall of the lumen, the impurities are controlled to leave the lumen through water impact. At the same time, the surface of the cleaning brush 20 can also be rinsed, which can achieve the effect of changing the friction of the cleaning brush 20 on the inner wall of the lumen by reciprocating brushing, thereby enhancing the cleaning effect of the inner wall of the lumen, and prevent the cleaning brush 20 from always fitting with the inner wall of the lumen, causing too many impurities to 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 laparoscope lumen, the outer wall of the lumen can also be cleaned synchronously by the first pool body 101 and the second pool body 102 to achieve the effect of continuous cleaning of the laparoscope lumen.

[0056] See also Figures 1-8 、 Figure 10 The follow-up telescopic mechanism includes a guide column 21 fixedly mounted on the movable plate 7, a support sleeve 25 is slidably mounted on the guide column 21, a follow-up plate 29 rotatably connected to the rotating sleeve 16 is fixed on the support sleeve 25, and an elastic component connected to the second rotating rod 14 is provided on the guide column 21, wherein the elastic component includes a guide groove opened on the outer wall of the circumference of the second rotating rod 14, a movable ring 22 is fixed to the end of the support sleeve 25, and a first limiting column 23 slidably connected to the guide groove is fixed on the movable ring 22, and a spring 24 abutting against the movable ring 22 is provided on the guide column 21.

[0057] Furthermore, the guide groove can be divided into three sections, namely the arc groove 1401, the spiral groove 1402, and the margin groove 1403, and the two ends of the spiral groove 1402 are respectively connected to the ends of the arc groove 1401 and the margin groove 1403. In the initial state, the first limiting post 23 is located in the arc groove 1401, so that the distance between the movable ring 22 and the movable plate 7 is minimized. Under the action of the movable ring 22, the support sleeve 25 and the follower plate 29 are used to control the distance between the rotating sleeve 16 and the movable plate 7 to be minimized, so as to control the distance between the two cleaning brushes 20 to be minimized 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 Release, and drive the movable ring 22 to move in the direction away from the movable plate 7 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 to control the two cleaning brushes 20 to move in the direction away from each other through the connecting rod 17. The bristles of the cleaning brush 20 will gradually fit into the inner wall of the lumen, and the brushing force on the inner wall of the lumen will gradually increase. When the first limiting column 23 disengages from the spiral groove 1402 and enters the end of the stroke of the margin groove 1403, the distance between the cleaning brushes 20 is the largest. When the first limiting column 23 disengages from the margin groove 1403 and enters the other spiral groove 1402, the movable ring 22 moves toward the initial position, and the two cleaning brushes 20 move in the direction of approaching each other until the first limiting column 23 returns to the arc groove 1401, and repeats the above steps to achieve brushing of the inner wall of the lumen.

[0058] 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, and according to the parallelogram law, when the distance between the two cleaning brushes 20 changes, a certain displacement will also occur in the vertical direction. Therefore, the cleaning brush 20 can provide rotational friction to the inner wall of the lumen while also providing friction in the vertical direction to ensure the best cleaning effect on the inner wall of the lumen.

[0059] See also Figure 1-Figure 7 、 Figure 9 、 Figure 10The gradual control mechanism includes a connecting plate 26 slidably mounted on the supporting sleeve 25, and a limiting ring 28 mounted on the second rotating rod 14 is fixed on the connecting plate 26, and the limiting ring 28 cooperates with the first limiting column 23, and a second limiting column 27 is also fixed on the connecting plate 26, and a guide assembly connected to the second limiting column 27 is provided on the first rotating rod 11, wherein the guide assembly includes a rotating disk 13 fixedly mounted on the end of the first rotating rod 11, and the outer wall of the rotating disk 13 is provided with an upper annular groove 1301, an inclined groove 1302, and a lower annular groove 1303 that are symmetrically arranged, and the second limiting column 27 can slide along the upper annular groove 1301, the inclined groove 1302, and the lower annular groove 1303.

[0060] Furthermore, four second rotating rods 14 are provided. 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 minimized, and the second limiting post 27 is located in the upper ring groove 1301, so as to control the limiting ring 28 to be located at the end of the stroke toward 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 margin groove 1403 is minimized. When the first limiting post 23 moves into the margin groove 1403, it will abut against the limiting ring 28, so that the displacement of the movable ring 22 along the length direction of the guide post 21 is small. Therefore, the unfolded distance between the two cleaning brushes 20 is also small. 11 will also drive the rotating disk 13 to rotate, so 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 in the direction away from the movable plate 7, so that the conduction amount of the residual groove 1403 increases. Therefore, the displacement of the movable ring 22 also increases, so that the expansion distance between the two cleaning brushes 20 increases, and the cleaning force of the cleaning brush 20 on the inner wall of the tubular cavity increases. 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, the residual groove 1403 is fully conductive, and the expansion distance between the two cleaning brushes 20 reaches the maximum.

[0061] Preferably, when the second limiting column 27 slides along the upper annular groove 1301, the inclined groove 1302, and the lower annular groove 1303, the maximum spacing of the cleaning brush 20 will be adjusted synchronously, thereby adjusting the brushing force on the inner wall of the lumen. When the spacing between the cleaning brush 20 and the inner wall of the lumen changes, the friction force will be continuously changed to achieve the effect of brushing the impurities remaining on the inner wall of the lumen by acting on the inner wall of the lumen with different friction forces, thereby further enhancing the brushing effect on the impurities. After the brushing is completed, the water remaining on the inner and outer walls of the laparoscope lumen can be blown dry with an air gun, and then packaged after ultraviolet disinfection.

[0062] A method for synchronously cleaning the inner and outer walls of a laparoscope lumen instrument comprises the following steps:

[0063] Step 1: Place the lumen instrument to be cleaned in the first tank 101 and wash the instrument with enzyme solution according to the proportion;

[0064] Step 2: After the enzyme washing is completed, the lumen instrument is moved into the second tank body 102 for ultrasonic cleaning;

[0065] Step 3: After ultrasonic cleaning is completed, the tubular device is moved into the third tank body 103, and the cleaning brush 20 is controlled to be inserted into the tubular device. Under the action of the driving mechanism, the cleaning brush 20 is controlled to rotate by the rotary cleaning mechanism and move along the length direction of the tubular device;

[0066] Step 4: At the same time, when the follow-up telescopic mechanism and the gradual control mechanism cooperate, the cleaning brush 20 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.
