Description

Special intelligent cleaning and disinfecting integrated equipment for bone drill surgical instruments and operation method thereof
Technical Field
The application relates to the technical field of special cleaning of surgical instruments, in particular to intelligent cleaning and disinfecting integrated equipment special for bone drill surgical instruments and an operation method thereof.
Background
The cleaning device for surgical instruments such as bone drills is a device specially designed for cleaning and treating surgical instruments such as bone drills, and plays a vital role in the medical field. The device is widely applied to the medical fields of orthopaedics, osteoarthropathy, dentistry (including oral surgery) and the like, and is especially indispensable to the drilling operation of long bones of limbs in orthopaedics wound operation. With the development of medical technology, the requirements on the accuracy and safety of operations are increasingly increased, which directly promotes the continuous improvement of the cleaning and disinfection standards of surgical instruments, particularly fine instruments such as bone drills and the like.
In the existing medical practice, surgical instruments such as bone drills and the like need to be strictly cleaned and disinfected before and after use so as to prevent cross infection and improve the success rate of the operation. Thus, the performance of the bone drill cleaning machine directly affects the effectiveness of the surgical instrument and patient safety. Existing cleaning methods and apparatus, while capable of meeting cleaning requirements to some extent, still have some limitations and disadvantages.
For example, the prior CN113842232a patent discloses a bone drill cleaning machine which adopts a soaking type cleaning method to clean and sterilize bone drill by soaking the bone drill in a specific cleaning liquid, controlling the liquid level, temperature and composition and soaking time of the cleaning liquid in the cleaning tank. This method is simple to handle, but has a relatively low cleaning efficiency, and particularly when dealing with a large number or complex shape of bone drills, it takes a longer time to ensure a sufficient cleaning effect. In addition, the soaking type cleaning can lead to water seepage of the bone drill, and the sealing performance of the bone drill is required to a great extent, so that the application of the bone drill in the cleaning of precise surgical instruments is limited to a certain extent.
The immersion cleaning may also not completely remove the higher hardness dirt and precipitate adhering to the bone drill, which not only affects the cleaning quality, but may also negatively affect the disinfection effect of the bone drill. Particularly in delicate surgery, any small residue can have a significant impact on the outcome of the surgery. In addition, cleaning with normal temperature cleaning fluids often makes it difficult to achieve the desired disinfection results 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, there is still a need for further improvement in cleaning efficiency, cleaning quality, disinfection effect, and the like. Particularly in the treatment of delicate and complex surgical instruments, there is a need for more efficient and thorough cleaning and sterilization methods. This requires a more intelligent and automated design of the bone drill cleaning machine to accommodate the ever-increasing medical needs, ensuring that the cleaning and sterilization of surgical instruments meets higher hygienic standards.
It can be seen that in order to solve the above problems, there is an urgent need for a bone drill type surgical instrument cleaning apparatus employing a more advanced cleaning technique.

Preferably, the bone drill seat 9 is adjustable in size to accommodate different types of bone drill 10.
Wherein a temperature-adjustable instant water heater 25 is arranged downstream of the tap water pipe electromagnetic valve to adjust the water temperature entering the cleaning solution tank.
Preferably, the control unit controls the operation of the solenoid valve, the pump, the adjustable temperature, i.e. the water heater.
Correspondingly, the operation method of the intelligent cleaning and disinfecting integrated equipment special for the bone drill surgical instruments comprises the following steps of:
step one, starting a power supply, namely switching on the power supply by an operator to provide electric energy for equipment, and ensuring that all systems and components can work normally;
Step two, preparing work, namely opening the cleaning and disinfecting space door 2-1 by an operator, and pulling out the bone drill cleaning workbench 4 from the cleaning and disinfecting space 2 so as to load the bone drill 10 to be cleaned;
Loading the bone drill, namely correctly mounting the bone drill 10 to be cleaned on the bone drill seat 9, and ensuring that the bone drill is stably placed so as to carry out subsequent cleaning and disinfection processes;
Step four, starting a cleaning program, namely pressing a starting button at the front end of the equipment by an operator to formally start the cleaning program, wherein the equipment enters an automatic operation mode at the moment, and automatically identifying the number of bone drills 10 on a current bone drill cleaning workbench by the equipment through a built-in image identification system to provide parameters for a subsequent cleaning process;
Step five, starting cleaning, namely starting to work an enzyme liquid pump 18, an upper and lower spray head cleaning liquid pump 16 and a drill bit clamp spray head cleaning liquid pump 26 according to the number of the automatically identified bone drills, and starting corresponding electromagnetic valves;
Step six, pulse cleaning, namely, the equipment carries out pulse cleaning on the drill bit clamp and the drill body, and dirt and residues on the surface of the bone drill are effectively removed through pulse water flow in a set time of 1-300 seconds;
Step seven, rinsing for the first time, namely starting the upper and lower spray head pure water pumps 17 and the drill bit clamp spray head pure water pump 27 to work, and performing the first rinsing, wherein pure water is sprayed out through the corresponding spray heads to remove cleaning liquid and residual dirt on the surface of the bone drill, and the rinsing time is also set to be 1-300 seconds;
step eight, rinsing for the second time, namely repeating the operation of the step seven, and rinsing for the second time to ensure that the cleaning liquid and residual dirt on the surface of the bone drill are thoroughly removed;
Step nine, drying and sterilizing, namely after the cleaning process is finished, the hot air supply and heat air sterilization system 5 starts to work to generate hot air, the hot air enters from the bone drill hot air inlet 5-1 and is discharged through the bone drill inner air outlet 5-2, so that the bone drill after cleaning is dried and sterilized, wherein in the sterilizing process, the temperature is maintained at 90 ℃, the quantitative index of the Ao value sterilizing effect is greater than 600, and the sterilizing time is controlled to be 1-30 minutes;
and step ten, after the drying and the sterilization are finished, the equipment automatically discharges hot air in the cleaning and sterilizing space 2, then the sterilizer stops working, and gives out a prompt tone for finishing the alarm, and the whole cleaning and sterilizing process is finished.
In the step ten, after the drying and the sterilization are finished, the heat supply and air exhaust sterilization system 5 works to generate normal-temperature air, and hot air in the cleaning and sterilizing space 2 is exhausted through the water outlet. The water outlet can discharge the hot air in the cleaning and sterilizing space rapidly, so that the bone drill is cooled down rapidly. In addition, the cooling process of the cleaning and sterilizing space can be quickened by exhausting hot air, and the time of the whole sterilizing period is shortened. Therefore, the working efficiency of the equipment can be improved, and the time is saved. Furthermore, through timely exhaust steam, can reduce the chance that operating personnel contacted with steam, reduce the risk of scalding or thermal burn.
In the fifth step, a camera is arranged in the cleaning and disinfecting space 2 so as to be capable of shooting bone drills placed in the cleaning and disinfecting space, and the position and the number of each bone drill are detected and identified through an image processing algorithm, so that a drill bit clamp spray head corresponding to the bone drill is started. And fifthly, in the beginning stage of the whole flow, the enzyme liquid pump, the upper and lower spray head cleaning liquid pump and the drill bit clamp spray head cleaning liquid pump start to work, corresponding electromagnetic valves are opened, and cleaning water flows are sprayed out from the upper spray head, the lower spray head and the drill bit clamp spray head to start cleaning. The main function of this step is to clean the impurities inside, outside and drill bit holder of the bone drill, ready for subsequent rinsing and sterilization.
And step six, cleaning the drill bit clamp and the drill body by using a pulse cleaning technology for 1-300 seconds. Pulse cleaning is an efficient decontamination method that can wash stubborn dirt from drill bit holders and drill bit bodies by rapidly changing water flow pressure. This step makes the bone drill cleaner, reduces the difficulty of rinsing and disinfection.
Step seven, rinsing for the first time by using a pure water pump. The purpose of rinsing is to rinse the cleaning liquid and residual impurities clean, and prepare for the next rinsing and disinfection. Rinsing with pure water ensures that the bone drill is free of any residual cleaning agent.
Step eight is a second rinse, again 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 sanitary.
And step nine, drying and sterilizing, namely drying and sterilizing the cleaned bone drill by using hot air generated by a hot air supply and sterilization system, wherein the temperature is 90 ℃, the Ao value is more than 600, and the time is 1-30 minutes. The drying and disinfection can effectively kill various microorganisms and prevent cross infection. The heat supply and exhaust air sterilization system has reliable sterilization effect, and can ensure complete sterilization of the bone drill, thereby being beneficial to reducing postoperative infection and complications.
Further, in order to reduce the heating power of the temperature-adjustable water heater 25, the water temperature entering the cleaning solution tank is adjusted by heating and matching with a heat exchange system as shown in fig. 7.
The heat exchange system comprises a cylindrical tank 29, a spiral pipe 30, a tap water inlet, a tap water outlet, a waste water inlet and a waste water outlet, wherein the spiral pipe is arranged in the heat exchange box, one end of the spiral pipe is the tap water inlet, a tap water pipe is connected with a tap water pipe through a temperature-adjustable water heater 25 and a tap water pipe electromagnetic valve, the other end of the spiral pipe is the tap water outlet and is connected with a cleaning liquid tank 13, the waste water inlet and the waste water outlet are arranged on the cylindrical tank 29, the waste water inlet is communicated with a drain outlet 24 and is arranged at the top of the side face of the cylindrical tank 29, the waste water outlet is arranged at the bottom of the side face of the cylindrical tank 29, and the waste water is discharged to a sewage treatment system 28 through an overflow pipe.
Wherein the hot wastewater is introduced from the top of the cylindrical tank 29 at a speed tangential to the wall and the fluid is swirled. At the bottom, the colder wastewater is discharged through an 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, mixing between the colder and hot wastewater is minimized. This results in a relatively high water temperature in the cylindrical tank 29 after filling/emptying is completed. If the flow rate is high enough, the cold water is rapidly driven out and the vortex forms well at the top, and the mixing of the hot and cold wastewater waters is limited. Therefore, after the disinfectant has been drained, the temperature in the cylindrical tank 29 is quite high.
For efficient heat recovery, the performance and length of the coil 30 is calculated, and the heat transferred to the cold water in the coil 30 is:
(1)
(2)

(5)
Wherein m tank is the water mass in the tank body.
The total heat transfer coefficient k is determined as:
(6)
Wherein d u is the outside diameter of the tube, d i is the inside diameter of the tube, h i is the inside convection coefficient, h i is the outside convection coefficient, Is the thermal conductivity.

The system of calculation equations is established using the above equation, and for each time step, assuming a constant water temperature in the cylindrical tank 29, the temperature of the water leaving the coil 30 is determined using equation (4). At this temperature, the transferred heat is calculated using equation (1), and then the new water temperature in the cylindrical tank 29 can be calculated using equation (5).
After the control unit determines the temperature of the water leaving the coil 30, it calculates the heating power of the variable temperature water heater 25 to further heat the tap water to meet the cleaning water temperature requirements while reducing the energy consumption of the variable temperature water heater 25 alone.
In addition, when step nine is dried and disinfected and step ten is discharged hot gas, the generated hot waste gas can enter the heat exchange system through the water outlet, hot gas is formed for preheating cold water in the spiral pipe, the heat of the system is fully utilized, and the energy consumption is further reduced.
