Description
Technical Field
[0001] The invention belongs to the technical field of cleaning, and in particular relates to a reciprocating threading automatic cleaning system for cleaning a lumen of a flexible endoscope. Background Art
[0002] Endoscope is a commonly used minimally invasive or non-invasive medical device. It consists of a curved part, a light source and a set of lenses. It enters the human body through the natural channels of the human body or through a small incision made during surgery. When used, the endoscope is introduced into the organ to be examined to directly observe the changes in the relevant parts and perform necessary treatment or surgery.
[0003] Compared with traditional surgical operations, minimally invasive surgical techniques for medical endoscopes have been widely accepted. At present, the main cleaning and disinfection methods for soft endoscopes in hospitals are manual cleaning plus microwave vibration cleaning, decompression boiling machine, etc., but these methods are still not ideal for cleaning the cavity. At present, according to the cleaning process part of the national disinfection technical specifications, it is required that the soft endoscope must be manually pre-cleaned before being placed in the automatic cleaning machine. Manual pre-cleaning is an important part of the current soft endoscope cleaning process (SOP). According to actual work surveys, soft endoscopes are completely manually cleaned, accounting for 60% of the total cleaning volume, especially in domestic municipal and county hospitals. Cleaning personnel need to walk continuously for each procedure, with a huge workload, easy fatigue, simple and boring work procedures, etc. In addition to low work efficiency and the fact that cleaning personnel repeatedly do the same work, which can easily cause fatigue, manual cleaning has the disadvantages of difficult to quantify or keep constant the scrubbing force and cleaning time, making it difficult to implement and guarantee the cleaning process (SOP) and quality standards. In short, the current cleaning efficiency and effect of soft endoscopes are still far from the actual requirements of nosocomial infection prevention. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The motor drives the active gear to rotate, so that the fixed pressing wheel rotates, and the handle is turned to rotate the lead screw, so that the movable frame moves downward, forcing the movable pressing wheel on the movable frame to move downward, so that the movable pressing wheel presses the threading wire. At the same time, the handle is turned to better adjust the pressing force of the movable pressing wheel on the threading wire. A wire spring is provided on the lead screw between the movable frame of the driving device and the inner wall of the box. One end of the wire spring supports the movable frame, and the other end supports the inner wall of the box. After the wire spring supports the inner wall of the box and the movable frame, the pressure of the fixed pressing wheel can be adjusted during the pushing operation of the threading wire (the pressure of the lead screw wire spring can be used in many ways, this time it is directly used, but it can also be used with an external lever), so as to adjust the pressure of the threading wire during transmission. The required force, speed and propulsion stability are determined by starting the driving device to propel the threading wire and the soft endoscope power tool cleaning brush. It is necessary to ensure that the driving device has sufficient force to push the threading wire into the fixed tube of the driving device, so that it enters the cleaning brush tube storage tube. At the same time, the threading wire transmits sufficient force to the soft endoscope special power cleaning brush in the cleaning brush storage tube, so that it leaves the cleaning brush storage tube, passes through the valve of the opened connector, and then passes through the soft endoscope tooling to enter the soft endoscope lumen, and quickly reciprocates to make a brushing motion. The active gear drives the fixed wire pressing wheel to rotate. If the power required for the soft endoscope cleaning brush needs to be strengthened, a second gear belt can be installed on the second driven gear and the third driven wheel at the other end of the first rotating shaft belt. The rotating shaft rotates, so that the fixed pressing wheel on the second rotating shaft rotates. The two fixed pressing wheels rotate and drive the threading wire together. The power is also doubled than that of the original single fixed pressing wheel. At the same time, the threading wire is wound in the round disc roller, and the end of the threading wire is fixed in the roller reel. The roller reel is connected to the connecting rod bearing, so that when the pressing wheel clamps the threading wire for transmission, the roller reel can advance, retreat, reverse, and transmit continuously, or jog. The roller reel can advance and retreat with the threading wire in an infinitely variable speed regulation manner, which is more efficient. After the threading wire passes through the fixed tube on one side of the drive device housing, the diameter of the soft endoscope power cleaning brush placed in the cleaning brush storage duct is connected to the threading wire exposed outside the fixed tube, so that the soft endoscope power cleaning brush can be placed in the cleaning brush storage duct. The endoscope power cleaning brush and the threading wire in the threading drive device are integrated, and the female connector near the cleaning brush storage tube is connected to the male connector near the driving device fixed tube, and the first mortise and tenon are connected with the second mortise and tenon, and the first tongue is connected with the second mortise and tenon, so that the male connector and the female connector are connected more tightly. At the same time, when the female connector is pushed, the buckle plate of the inclined surface contacts the protrusion on the male connector, and the buckle plate moves to the rear of the protrusion, so that the buckle plate is better clamped, and the connector connection speed is faster. The spring on the bottom of the buckle plate can better clamp the buckle plate. When opening, press the tail end of the buckle plate at the same time to make one end of the buckle plate tilt up, so that the male connector and the female connector are separated, so that the catheter can be better connected. Before this,The male quick connector at the other end of the cleaning brush storage catheter has been connected to the female connector on the connecting pipe with a series valve. At the same time, the female quick connector with a sensor at the other end of the connecting pipe with the valve has been connected to the male quick connector close to the flexible endoscope tooling catheter. Make sure that all male and female connectors from the drive device to the flexible endoscope are connected. Confirm that the threading wire in the catheter and the flexible endoscope power cleaning brush are fully connected. At the same time, confirm that the connector, the one-way valve on the connecting pipe, and the valve are working normally, and then start each cleaning program in sequence, such as cleaning enzyme cavity perfusion, driving threading wire and soft endoscope cleaning brush, cavity pure water perfusion and rinsing, blow-drying, cavity disinfectant perfusion soaking, rinsing, blow-drying, alcohol disinfection and other procedures.

[0029] In this embodiment, the driving gear 30 is driven to rotate by the motor 22, and the first gear belt 31 is meshed with the driving gear 20 and the first driven gear 32, so that the first driven gear 32 drives the first rotating shaft 23 to rotate, so that the fixed pressing wheel 21 rotates, and at the same time, the first rotating shaft 23 drives the second driven gear 24 at the other end to rotate, and at the same time, the second gear belt 25 is meshed with the second driven gear 26 and the third driven gear 27, so that the second rotating shaft 27 rotates, so that the fixed pressing wheel 21 on the second rotating shaft 27 rotates, and at the same time, the screw rod 12 is rotated by rotating the handle 11, and the screw rod outer sleeve steel wire spring 43 between the inner wall of the driving device housing 1 and the movable frame, and at the same time, the slider 16 at one end of the screw rod 12 slides with the slide groove 17 on the movable frame 18. The movable frame 18 is connected to the driving device housing 1 by a screw thread, so that the movable frame 18 moves downward, and the movable pressing wheel 19 on the movable frame 18 moves downward, so that the movable pressing wheel 19 presses the threading wire 50. At the same time, the pressing force of the movable pressing wheel 19 on the threading wire 50 is better adjusted by rotating the handle 11, and the pressure of the pressing wheel on the threading wire 50 is adjusted. The wire spring 43 is mounted on the screw rod 12 between the inner wall of the driving device housing 1 and the movable frame. The wire spring 43 can automatically adjust the pressure of the movable pressing wheel 19 through its elastic force on the movable frame 18, so as to achieve the adjustment of the force, speed and stability of the threading wire 50 when transmitting. At the same time, at least one pair of movable crimping wheels 19 and fixed crimping wheels 21 are required. When necessary, a second gear belt 25 is added to drive the threading wire 50 with another movable crimping wheel 19 and another fixed crimping wheel 21 to increase the original double driving force. When multiple sets of movable crimping wheels 19 and multiple sets of fixed crimping wheels 21 are set, the driving forces are multiplied by multiple sets. If the connecting card plate 29 on the second group of movable frames 18 and fixed plates 20 is opened, the second rotating shaft 27, the third driven gear 26 and the fixed crimping wheel 21 are placed on the second group of movable frames 18 and fixed plates 20, and the connecting card plate 29 is fixed to the second group of movable frames 18 and fixed plates 20 with bolts, and the second gear belt 25 is added again.

The spring 28 on the bottom surface of the snap plate 38 is used to better clamp the snap plate 38. When opening, press the tail end of the snap plate 38 at the same time to make one end of the snap plate 38 tilt up, so that the male connector 6 and the female connector 7 are separated.

The purpose is to prevent the liquid from flowing back. The connector 9 is connected to the connecting conduit 10. The connector on the connecting conduit 10 is provided with a one-way valve 41. When the liquid perfuses the soft endoscope, this one-way valve 41 automatically opens. After the liquid perfusion cleaning procedure is completed, the one-way valve 41 automatically closes.

The power cleaning brush enters the lumen of the connector 9. The other end of the connector 9 is connected to a female connector 46. The front end of the snap plate 38 of the female connector 46 is provided with a pressure sensor 40. At the same time, the pressure sensor 40 on the snap plate 38 contacts the bump 33 to better determine that the connector is connected. The purpose of the pressure sensor 40 is to ensure that the female connector 46 is completely sealed and connected to the male connector 47, so as to ensure that the soft endoscope power cleaning brush passes smoothly through the female connector 46 and the male connector 47, and through the flexible endoscope tooling catheter 48 and the flexible endoscope tooling 49, and at the same time through the biopsy port or steam port water port of the flexible endoscope, the soft endoscope power cleaning brush is completed.

The connecting clamps 29 on the second group of movable frames 18 and the fixed plate 20 are opened to place the second rotating shaft 27, the third driven gear 26 and the fixed wire pressing wheel 21 on the second group of movable frames 18 and the fixed plate 20, and then the connecting clamps 29 are fixed to the second group of movable frames 18 and the fixed plate 20 with bolts, and the second gear belt 25 is replaced again to better rotate the multiple fixed wire pressing wheels 21. At the same time, the pressure can be better controlled through the movable wire pressing wheel 19 on the second group of movable frames 18.
[0039] Working principle and use process of the present invention: After the present invention is installed, when in use, the motor 22 drives the driving gear 30 to rotate, and the first gear belt 31 meshes with the driving gear 20 and the first driven gear 32, so that the first driven gear 32 drives the first rotating shaft 23 to rotate, so that the fixed pressing wheel 21 rotates, and at the same time, the first rotating shaft 23 drives the second driven gear 24 at the other end to rotate, and at the same time, the second gear belt 25 meshes with the second driven gear 26 and the third driven gear 27, so that the second rotating shaft 27 rotates, so that the fixed pressing wheel 21 on the second rotating shaft 27 rotates, and at the same time, the screw rod 12 is rotated by rotating the handle 11, and the screw rod outer sleeve steel wire spring 43 between the inner wall of the driving device box body 1 and the movable frame, and at the same time, the slider 16 at one end of the screw rod 12 is slidably connected with the slide groove 17 on the movable frame 18, so that the movable frame 1 can be better 8 moves downward, and at the same time, the screw rod 12 is threadedly connected with the driving device housing 1, so that the movable frame 18 moves downward, and the movable pressing wheel 19 on the movable frame 18 moves downward, so that the movable pressing wheel 19 presses the threading wire 50, and at the same time, the pressing force of the movable pressing wheel 19 on the threading wire 50 is better adjusted by turning the handle 11, and the pressure of the pressing wheel pressing the threading wire 50 is adjusted. The wire spring 43 is jacketed on the screw rod 12 between the inner wall of the driving device housing 1 and the movable frame. The wire spring 43 can automatically adjust the pressure of the movable pressing wheel 19 through its elastic force on the movable frame 18. At the same time, the movable pressing wheel 19 and the fixed pressing wheel 21 need at least one pair. When necessary, the second gear belt 25 is added to implement the threading wire 50 drive of another movable pressing wheel 19 and another fixed pressing wheel 21 to increase the original double driving force. When multiple sets of movable pressing wheels 19 and multiple sets of fixed pressing wheels 21 are set, their driving forces are all multiplied by multiple sets. If the connecting clamp 29 on the second group of movable frames 18 and the fixed plate 20 is opened, the second rotating shaft 27, the third driven gear 26 and the fixed pressing wheel 21 are also placed on the second group of movable frames 18 and the fixed plate 20, and the connecting clamp 29 is fixed to the second group of movable frames 18 and the fixed plate 20 with bolts, and the second gear belt 25 is added again. At this time, a total of 4 fixed pressing wheels 21 are driven to rotate, and 4 movable pressing wheels 19 work together to compress the threading wire 50. 4 pairs of fixed pressing wheels and movable pressing wheels are driven at the same time, and the driving force is 4 times that of the original pair of movable pressing wheels and fixed pressing wheels.At the same time, the threading wire 50 is wound in the circular disc roller, and the end of the threading wire 50 is fixed in the roller drum 15. At the same time, the roller drum 15 is connected to the bearing of the connecting rod 14, and the threading wire 50 is passed through the fixed tube 5 on one side of the drive device box 1. At the same time, the female connector 7 is connected to the male connector 6 on the fixed tube 5, and the first mortise and tenon groove 35 is connected with the second mortise and tenon tongue 36, and the first mortise and tenon tongue 34 is connected with the second mortise and tenon groove 37, so that the male connector 6 The connection with the female connector 7 is tighter. At the same time, by pushing the female connector 7, the buckle plate 38 on the inclined surface contacts the protrusion 33 on the male connector 6, and the buckle plate 38 moves to the rear of the protrusion 33, so that the buckle plate 38 is better clamped, and the connector connection speed is faster. The buckle plate 38 is better clamped by the spring 28 on the bottom of the buckle plate 38. When opening, the tail end of the buckle plate 38 is pressed at the same time to make one end of the buckle plate 38 tilt up, so that the male connector 6 and the female connector 7 are separated. The completion of the connection between the male connector 6 and the female connector 7 ensures a better connection between the cleaning brush storage tube 8 and the driving device. The male connection head 44 at the other end of the cleaning brush storage tube 8 is buckled to connect the female connector 45, completing the connection between the cleaning storage tube 8 and the connector 9 that carries the input of various liquids. At the same time, the connector 9 is connected, and a valve 42 is provided on the connector 9. This valve 42 is closed before the liquid perfusion procedure of the flexible endoscope such as the cleaning enzyme solution is implemented, in order to prevent the liquid from flowing back. The connector 9 is connected to the connecting catheter 10, and a one-way valve 41 is provided on the connector of the connecting catheter 10. When the liquid perfuses the flexible endoscope, this one-way valve 41 automatically opens, and after the liquid perfusion cleaning procedure is completed, the one-way valve 41 automatically closes. The angle between the connecting tube 10 and the connector 9 through which the washing enzyme solution, disinfectant, pure water, alcohol, gas, and other fluids pass can be adjusted according to the usage, and the angle between the connecting tube 10 and the connector 9 is 0 degrees to 90 degrees. Through the one-way valve 41 on the connector 10, the inflow of fluid can be better controlled, which is more efficient and more convenient. At the same time, through the control of the valve 42, the backflow of the fluid on the connecting tube 10 can be better prevented. After that, the motor of the driving device is turned on, and all gears and the fixed wire pressing wheel begin to rotate. When the threading wire 50 is driven to move, the valve 42 opens, allowing the threading wire 50 to first pass through the cavities of the male connector 6 and the female connector 7 and enter the cleaning brush storage tube 8, while pushing the soft endoscope power cleaning brush that is pre-connected with the threading wire 50 and pre-placed in the cleaning brush storage tube 8.The soft endoscope power cleaning brush enters the lumen of the connector 9, and the other end of the connector 9 is connected to a female connector 46. The front end of the snap plate 38 of the female connector 46 is provided with a pressure sensor 40. At the same time, the pressure sensor 40 on the snap plate 38 contacts the bump 33 to better determine that the connector is connected. The purpose of the pressure sensor 40 is to ensure that the female connector 46 is completely sealed to connect the male connector 47 to ensure that the soft endoscope power cleaning brush passes through the female connector 46 and the male connector 47 smoothly, and through the connection of the soft endoscope tooling catheter 48 and the soft endoscope tooling 49, and at the same time through the biopsy port or steam port water port of the soft endoscope, the soft endoscope power cleaning brush is completed. Efficient cleaning in the soft endoscope tube. The input ends of the electrical equipment in this device are all electrically connected to the external power supply, and the device has an operation panel of an embedded software automatic operating system.
[0040] Before turning on the power, first connect the flexible endoscope tooling to the biopsy port or the air port and water port to ensure that the flexible endoscope and the flexible endoscope tooling, connector and catheter are completely unobstructed without leakage. At the same time, close the air holes or water inlet holes at the laparoscope handle and the connection part. If the connection part is the air hole and the water inlet hole, the biopsy port can be closed first. In principle, only one hole at the front end of the flexible endoscope is opened to ensure that various liquids are injected into the laparoscope and the state of smooth unobstructedness is prepared for the washing enzyme solution, disinfectant, flushing solution, alcohol, and gas circulation out. Similarly, after starting the embedded driver of the flexible endoscope power cleaning brush, when it is reciprocated back and forth, let the brush head extend from the front end and reciprocate again to achieve the effect of thoroughly brushing the serpentine part and the front end lumen. If it is a duodenoscope, the lifting forceps needs to be opened manually or automatically according to the embedded program. At this time, the brush can thoroughly brush the lifting forceps channel.
[0041] After the power switch is turned on, the entire integrated embedded cleaning software system is started. When the cleaning program is started, the software program operation requirements are as follows: Close the valve 42 of the connecting tube 9 to prevent liquid backflow. First, according to the different stages of cleaning and different needs, when the liquid or gas passes through, the one-way valves 41 of the multiple connecting tubes 10 on the connector 9 are automatically opened. The one-way valve does not need to be controlled by the software system. The washing enzyme solution, disinfectant, pure water, and compressed gas pass through the valves on their respective connecting tubes 10 and are injected into the flexible endoscope cavity through the connector 9. Start the software program for injecting various liquids or gases according to demand. For example, after starting the injection program of the washing enzyme liquid injection pump or the running water injection pump, the injected washing enzyme liquid or water will automatically pass through the one-way valve 41 and enter the flexible endoscope cavity through one end of the connector 9. The perfusion of the washing enzyme solution has two main functions. One is to remove the dirt in the lumen of the digestive flexible endoscope, and the other is to lubricate the flexible endoscope power cleaning brush, so that the flexible endoscope power cleaning brush can easily and quickly enter the flexible endoscope, and then facilitate the flexible endoscope power cleaning brush to perform multiple reciprocating motions to achieve the purpose of thoroughly brushing the flexible endoscope cavity.
[0042] At this time, the software program controls the valve 42 to be in a closed state to prevent liquid or gas from flowing back into the cleaning brush storage tube 8 through the connecting tube 9, and further flowing back to the driving device 1 to pollute the environment. After the cleaning enzyme solution is perfused, the software program turns on the motor 22 of the driving device 1, and each gear and the fixed wire pressing wheel 21 start and rotate according to the embedded program. When the threading wire 50 is driven to move, the valve 42 is opened in the design software program, allowing the threading wire 50 to pass through the male connector 6 and the female connector 7 first, and enter the cleaning brush storage tube 8, while pushing the soft endoscope power cleaning brush that is pre-connected with the threading wire 50 and pre-placed in the cleaning brush storage tube 8. The soft endoscope power cleaning brush enters the lumen of the connector 9 and the connecting tube, and passes through the biopsy port or the steam port water port of the soft endoscope by connecting the soft endoscope tooling catheter 48 and the soft endoscope tooling 49, and at the same time completes the efficient cleaning of the soft endoscope power cleaning brush in the soft endoscope tube according to the design program.
[0043] When the motor 22 that pushes the threading wire 50 runs according to the program, the shaft is driven to rotate, and the pressure wheel is driven by the above-mentioned multiple sets of gears. The entire rotation can be implemented in forward and reverse according to the software program. The purpose is to realize the insertion and retraction of the soft endoscope power cleaning brush in the soft endoscope cavity. It can not only ensure the friction between the brush and the lumen wall, but also limit the direction of the cleaning brush and the number of back and forth brushing. The speed of the motor push is stable and powerful, that is, to improve the stability of the cleaning brush when moving. With the sufficient power of the designed machine and the characteristics of software automatic control, it is completely possible to ensure the smooth collection and release of the cleaning brush, save time, and reduce the labor intensity of the cleaning staff. On the entire 1600-2200mm long soft endoscope power cleaning brush, there is a 5-100mm long bristle body every 20-600mm, so when this soft endoscope power cleaning brush enters the cavity, the drive device 1 will continuously alternate forward and reverse rotation for more than 5 times according to the software program. The continuous alternation of forward and reverse rotation must ensure that the soft endoscope power cleaning brush has a back and forth movement distance of about 20-700mm in the soft laparoscope cavity (the time required for one reciprocating movement can be designed based on the principle of operating speed * operating time = operating distance). This can ensure that every part of the entire cavity is fully and thoroughly cleaned, and avoid cleaning blind spots in the lumen that are not properly cleaned.
[0044] The reciprocating scrubbing motion of the soft endoscope power cleaning brush is driven by the motion of the threading wire 50 connected thereto, and the motion of the threading wire 50 is implemented by the thrust generated by the squeezing and rotation of the fixed wire pressing wheel 21 of the driving device. The length of the threading wire 50 is generally 400-3000mm, and the diameter, softness and toughness of the threading wire are selected according to the power requirements.
[0045] After the soft endoscope power cleaning brush finishes brushing according to the required number of cleaning times and time, the threading wire 50 is rolled out of the cleaning brush storage tube 8 in the established software program design under the pressure drive of the fixed wire pressing wheel 21 of the driving device 1. At this time, the roller reel 15 also helps to roll up and retract the threading wire 50 as the roller rotates, and the soft endoscope power cleaning brush is also automatically retracted into the cleaning brush storage tube 8 according to the set program.
[0046] When the washing enzyme solution is perfused and the soft endoscope power cleaning brush is reciprocated and scrubbed according to the program, the embedded software program will start the pure water flushing according to the program, and then start the compressed air blowing program to dry the soft endoscope lumen. Similarly, when the liquid perfusion or gas drying program is started, the valve 42 is in the closed state according to the program design.
[0047] If the disinfectant is selected as the disinfection program, press the disinfection cleaning button. The required design program and implementation process are similar to those of the cleaning enzyme solution. The difference is that different disinfectants have different soaking times, and the required disinfection time is different from the cleaning enzyme infusion time. The cleaning and drying procedures required for disinfection cleaning are similar to the rinsing and drying procedures after cleaning enzyme cleaning.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
