Description

Technical Field

[0001] The present application relates to the field of cleaning technology for surgical instruments, and in particular to an intelligent integrated cleaning and disinfection device for bone drill-type surgical instruments and an operating method thereof. Background Art

[0002] Bone drill and other surgical instrument cleaning equipment is a kind of equipment specially designed for cleaning and processing bone drill and other surgical instruments, which plays a vital role in the medical field. This kind of equipment is widely used in medical fields such as orthopedics, osteoarthritis, dentistry (including oral surgery), etc., especially in orthopedic trauma surgery, for the drilling operation of long bones of limbs, the use of bone drill cleaning machine is indispensable. With the development of medical technology, the precision and safety requirements of surgery are increasing day by day, which directly promotes the continuous improvement of the cleaning and disinfection standards of surgical instruments, especially fine instruments such as bone drills.

[0003] In existing medical practice, surgical instruments such as bone drills need to be strictly cleaned and disinfected before and after use to prevent cross infection and improve the success rate of surgery. Therefore, the performance of bone drill cleaning machines directly affects the use effect of surgical instruments and patient safety. Although existing cleaning methods and equipment can meet the cleaning needs to a certain extent, they still have some limitations and shortcomings.

[0004] For example, the existing CN113842232A patent discloses a bone drill cleaning machine, which adopts an immersion cleaning method to clean and disinfect the bone drill by immersing the bone drill in a specific cleaning liquid, controlling the liquid level, temperature, composition and immersion time of the cleaning liquid in the cleaning tank. This method is relatively simple to operate, but its cleaning efficiency is relatively low, especially when dealing with a large number of bone drills or bone drills of complex shapes, it takes a longer time to ensure a sufficient cleaning effect. In addition, immersion cleaning may cause water seepage in the bone drill, which places extremely high requirements on the sealing of the bone drill, which to a certain extent limits its application in the cleaning of precision surgical instruments.

[0005] Immersion cleaning may also fail to completely remove the hard dirt and sediment attached to the bone drill, which not only affects the cleaning quality, but may also have a negative impact on the disinfection effect of the bone drill. Especially in precision surgery, any tiny residue may have a significant impact on the outcome of the operation. In addition, it is often difficult to achieve the ideal disinfection effect when using room temperature cleaning fluid for cleaning, because many bacteria and viruses need to be effectively killed at higher temperatures. Therefore, although the bone drill cleaning machine of CN113842232A provides a solution for bone drill cleaning, it still needs to be further improved in terms of cleaning efficiency, cleaning quality, and disinfection effect. Especially when handling precise and complex surgical instruments, more efficient and thorough cleaning and disinfection methods are needed. This requires that the bone drill cleaning machine needs to be more intelligent and automated in design to meet the growing medical needs and ensure that the cleaning and disinfection of surgical instruments can meet higher hygiene standards.

[0006] It can be seen that in order to solve the above problems, a bone drill surgical instrument cleaning device using more advanced cleaning technology is urgently needed. Summary of the invention

[0052] A drain port 19 is designed on the bottom wall of the cleaning and disinfection space 2, and waste water is discharged from the drain port 24 on the back of the equipment body 1 through the drain port control valve 20 and the drain pipe of the bottom cavity;

[0053] The hot air supply and exhaust disinfection system 5 is installed on one side wall and connected to the bone drill hot air inlet 5-1;

[0054] The control component installation space 3 integrates a control unit, a touch operation unit 11 , a start button and an emergency stop button 12 .

[0055] Preferably, the hot air supply and exhaust disinfection system includes: a heat source module: this module is responsible for generating hot air and uses an electric heater as a heat source; the electric heater is composed of a group of heating elements and a temperature controller, which can quickly heat up and maintain a constant working temperature; a fan and air duct module: the fan is responsible for transporting the heat generated by the heat source module to the inside of the cleaning and disinfection space through the air duct system; the fan adopts a centrifugal fan; the air duct system guides the hot air to the bone drill hot air inlet 5-1; a filter module: a filter module is installed in the air duct to filter the tiny particles and microorganisms contained in the hot air to prevent pollution to the environment; an intelligent control module: connected to the control unit of the equipment, receives operating instructions and coordinates the work of the hot air disinfection system, including starting, stopping, temperature adjustment and time setting.

[0056] Preferably, a temperature sensor is included, wherein the temperature sensor is used to monitor the temperature in the cleaning and disinfection space 2 in real time, and the control unit receives a signal from the temperature sensor and adjusts the output of the electric heater.

[0057] Preferably, the upper nozzle 6, the lower nozzle 7 and the drill clamp nozzle 8 of the cleaning and disinfection space 2 are all made of stainless steel, and the nozzle is configured as a detachable structure.

[0058] Preferably, the inner wall of the cleaning and disinfection space 2 is covered with an anti-corrosion material layer.

[0059] Preferably, the fan in the hot air supply and exhaust disinfection system 5 adopts frequency conversion control technology, and the operating speed of the fan is adjusted by a frequency converter.

[0060] Preferably, one end of the upper and lower nozzle cleaning liquid pump 16 is connected to the cleaning liquid tank 13 through a hose, and the other end is connected to the upper and lower nozzle common pipeline through a solenoid valve; one end of the upper and lower nozzle pure water pump 17 is connected to the pure water tank 15 through a hose, and the other end is connected to the upper and lower nozzle common pipeline through a solenoid valve; the upper and lower nozzle common pipeline is connected to compressed air through a solenoid valve; the downstream branch of the upper and lower nozzle common pipeline is connected to the upper nozzle 6 through the upper water spray joint 6-1, and connected to the lower nozzle 7 through the lower water spray joint 7-1.

[0062] The compressed air in the compressed air system of the present invention can be used to enhance the force of the nozzle spraying the cleaning liquid. Through the gas-liquid mixing technology, the impact force of the cleaning liquid on the surface of the bone drill is increased, and stubborn stains and biological residues are more effectively removed. Compressed air can be used to atomize the cleaning liquid to generate extremely fine droplets, which can cover the surface of the bone drill more evenly and provide a more detailed cleaning effect. During the maintenance of the cleaning and disinfection equipment, compressed air can be used to clean the inside of the nozzle, remove impurities that may clog the nozzle, and ensure the spraying effect of the nozzle. In some cases, compressed air can also be used for auxiliary operations, such as using compressed air to remove residual cleaning liquid in the tank during replacement of the cleaning liquid tank or other maintenance tasks.

[0063] Preferably, the cleaning and disinfection space 2 is provided with a cleaning and disinfection space door 2 - 1 .

[0064] Preferably, the bone drill seat 9 can be adjusted in size and can be adapted to bone drills 10 of different models.

[0065] A thermostatic water heater 25 is arranged downstream of the solenoid valve of the water pipe to adjust the temperature of the water entering the cleaning liquid tank.

[0066] Preferably, the control unit controls the operation of the solenoid valve, the pump, and the thermostatically adjustable water heater.

[0067] Correspondingly, a method for operating a dedicated intelligent cleaning and disinfection integrated device for bone drill surgical instruments comprises the following steps:

[0068] Step 1: Power on: The operator turns on the power to provide power to the equipment and ensure that all systems and components can work normally;

[0069] Step 2, preparation: the operator opens the cleaning and disinfection space door 2-1, and pulls the bone drill cleaning workbench 4 out of the cleaning and disinfection space 2 to load the bone drill 10 to be cleaned;

[0070] Step 3, loading the bone drill: correctly install the bone drill 10 to be cleaned on the bone drill seat 9, ensuring that the bone drill is firmly placed for subsequent cleaning and disinfection processes;

[0071] Step 4, start the cleaning process: the operator presses the start button on the front of the device to officially start the cleaning process; at this time, the device will enter the automatic operation mode; the device automatically identifies the number of bone drills 10 on the current bone drill cleaning workbench through the built-in image recognition system, and provides parameters for the subsequent cleaning process;

[0072] Step 5, start cleaning: according to the number of bone drills automatically identified, the enzyme liquid pump 18, the upper and lower nozzle cleaning liquid pumps 16 and the drill clamp nozzle cleaning liquid pump 26 start working, and the corresponding solenoid valves are also started; the cleaning liquid is sprayed through the upper nozzle 6, the lower nozzle 7 and the drill clamp nozzle 8 to perform preliminary cleaning on the bone drill;

[0073] Step 6: Pulse cleaning: The equipment performs pulse cleaning on the drill holder and drill body, with a set time of 1-300 seconds, and effectively removes dirt and residues on the surface of the bone drill through pulse water flow;

[0074] Step 7, first rinsing: the upper and lower nozzle pure water pumps 17 and the drill clamp nozzle pure water pump 27 start working to perform the first rinsing; pure water is sprayed through the corresponding nozzles to remove the cleaning liquid and residual dirt on the surface of the bone drill, and the rinsing time is also set to 1-300 seconds;

[0075] Step 8, second rinsing: Repeat the operation of step 7 and perform a second rinse to ensure that the cleaning fluid and residual dirt on the surface of the bone drill are completely removed;

[0076] Step nine, drying and disinfection: after the cleaning process is completed, the hot air supply and exhaust disinfection system 5 starts to work and generates hot air; the hot air enters from the hot air inlet 5-1 of the bone drill and is discharged through the exhaust port 5-2 inside the bone drill to achieve drying and disinfection of the cleaned bone drill; during the disinfection process, the temperature is maintained at 90 degrees Celsius, the quantitative index of the disinfection effect of the Ao value is greater than 600, and the disinfection time is controlled within 1-30 minutes;

[0077] Step 10, cleaning is completed: After the drying and disinfection is completed, the equipment automatically discharges the hot air in the cleaning and disinfection space 2, and then the disinfection machine stops working and issues a completion alarm prompt sound, and the entire cleaning and disinfection process is completed.

[0078] In step 10, after the drying and disinfection is completed, the hot air supply and exhaust disinfection system 5 operates to generate normal temperature wind, and the hot air in the cleaning and disinfection space 2 is discharged through the drain port. The drain port can quickly discharge the hot air in the cleaning and disinfection space, so that the bone drill can be quickly cooled down. In addition, the removal of hot air can speed up the cooling process of the cleaning and disinfection space and shorten the time of the entire disinfection cycle. This can improve the working efficiency of the equipment and save time. Moreover, by discharging the hot air in time, the chance of the operator contacting with the hot air can be reduced, reducing the risk of scalds or thermal burns.

[0079] Among them, in step five, a camera is set in the cleaning and disinfection space 2 so that the bone drill placed in the cleaning and disinfection space can be photographed, and the position and number of each bone drill are detected and identified through the image processing algorithm, and then the drill clamp nozzle corresponding to the bone drill is turned on. Step five is the starting stage of the whole process. The enzyme liquid pump, the upper and lower nozzle cleaning liquid pumps and the drill clamp nozzle cleaning liquid pump start working, the corresponding solenoid valve is opened, and the cleaning water flow is sprayed from the upper nozzle, the lower nozzle and the drill clamp nozzle to start cleaning. The main function of this step is to clean the impurities inside and outside the bone drill and the drill clamp, and prepare for subsequent rinsing and disinfection.

[0080] Step six is ​​to clean the drill holder and drill body using pulse cleaning technology for 1-300 seconds. Pulse cleaning is an efficient decontamination method that can wash away stubborn dirt from the drill holder and drill body through rapidly changing water pressure. This step makes the bone drill cleaner and reduces the difficulty of rinsing and disinfection.

[0081] Step seven is the first rinse, which is performed using a pure water pump. The purpose of rinsing is to rinse away the cleaning solution and residual impurities in preparation for the next rinse and disinfection. Using pure water for rinsing ensures that there is no residual cleaning agent on the bone drill.

[0082] Step eight is the second rinse, which is also performed using a pure water pump. This step further removes impurities and residual cleaning fluid that were not removed in the previous rinse, making the bone drill cleaner and more hygienic.

[0083] Step nine is drying and disinfection. Use the hot air supply and exhaust disinfection system to generate hot air to dry and disinfect the cleaned bone drill at a temperature of 90°C, an Ao value greater than 600, and a time of 1-30 minutes. Drying and disinfection can effectively kill various microorganisms and prevent cross infection. The hot air supply and exhaust disinfection system has a reliable disinfection effect and can ensure complete disinfection of the bone drill, thereby helping to reduce the occurrence of postoperative infection and complications.

[0084] Further, in order to reduce the heating power of the adjustable temperature instant water heater 25, the following method is adopted: Figure 7 The heat exchange system shown heats and regulates the temperature of the water entering the washer fluid tank.

[0085] Among them, the heat exchange system includes: a cylindrical tank body 29, a spiral tube 30, a tap water inlet, a tap water outlet, a waste water inlet and a waste water outlet; wherein the spiral tube is arranged inside the heat exchange box, one end of the spiral tube is the tap water inlet, which is connected to the tap water pipe through the adjustable temperature instant water heater 25 and the tap water pipe solenoid valve, and the other end is the tap water outlet, which is connected to the cleaning liquid tank 13; the waste water inlet and the waste water outlet are arranged on the cylindrical tank body 29, wherein the waste water inlet is connected to the drain outlet 24, which is arranged at the top of the side of the cylindrical tank body 29; the waste water outlet is arranged at the bottom of the side of the cylindrical tank body 29, and is discharged to the sewage treatment system 28 through the overflow pipe.

[0086] Among them, hot wastewater is introduced from the top of the cylindrical tank body 29, and the entry speed is tangential to the wall surface, and the fluid generates a vortex. At the bottom, the colder wastewater is discharged through the overflow pipe, so that the colder wastewater is discharged from the bottom by the hot wastewater entering from the top. Due to the tangential flow at the top, the mixing between the colder wastewater and the hot wastewater is minimized. This results in that the water temperature in the cylindrical tank body 29 is still quite high after the filling / emptying is completed. If the flow rate is high enough, the cold water is quickly driven out, and the vortex is well formed at the top, and the mixing of hot wastewater and cold wastewater is limited. Therefore, after the disinfectant is drained, the temperature in the cylindrical tank body 29 is quite high.

[0087] For effective heat recovery, the performance and length of the spiral tube 30 need to be calculated. The heat transferred to the cold water in the spiral tube 30 is:

At the same time, the stable workbench design effectively prevents the instrument from shifting during the cleaning process, thereby significantly improving the cleaning quality, ensuring the hygiene standards of the instrument, and providing solid equipment support for various medical operations.

[0118] (2) The present invention incorporates a hot air supply and exhaust disinfection system, which provides an efficient drying and disinfection method for cleaned bone drills. Compared with traditional chemical or ultraviolet disinfection methods, hot air disinfection is not only fast, but also more thorough and safer. The system can effectively eliminate microorganisms such as bacteria and viruses, greatly reducing the risk of infection and ensuring the hygienic safety of medical equipment. In addition, the temperature and working time of the system can be adjusted according to actual needs, enhancing the flexibility and controllability of the disinfection process.

The multi-nozzle design simplifies the placement process of the bone drill, and the touch screen control interface makes the equipment operation more intuitive and user-friendly, reduces the difficulty of operation, and improves the work efficiency of medical staff.

[0120] (4) The heat exchange system in the present invention makes full use of heat energy such as wastewater and hot air after disinfection to preheat cold water, effectively reducing energy consumption. During the preheating of tap water, the hot water output temperature is optimized by accurately calculating the performance and length of the spiral tube, thereby achieving efficient recovery of heat energy. The control unit automatically adjusts the heating power of the instant water heater according to the outlet water temperature, ensuring the stability and accuracy of the cleaning water temperature and further improving the cleaning effect. During the heat exchange process, multiple parameters such as the heat transfer coefficient, convection coefficient, and mass flow rate are comprehensively considered to ensure the optimal performance and efficiency of the system. While cooling the water in the cylindrical tank, the water in the spiral tube is more effectively heated, further improving the overall heat transfer efficiency.
