Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an ultrasonic-based gastrointestinal surgical instrument cleaning and disinfection device. Background Art

[0002] In gastrointestinal surgery, surgical instruments often come into contact with the patient's body fluids, tissues, etc., and are easily attached with a large amount of dirt and microorganisms. The ultrasonic cleaning and disinfection device is equipped with an ultrasonic transducer, which transmits energy to the cleaning fluid through high-frequency vibration. The tiny bubbles in the cleaning fluid expand and burst rapidly under the action of ultrasound, generating strong shock waves. These shock waves can penetrate the tiny gaps and holes on the surface of the surgical instrument and thoroughly clean the dirt, blood, tissue residues, etc.

[0003] The conventional existing technical solutions have the following defects: a large amount of dirt and microorganisms will adhere to the surgical instruments after the operation, which will be separated into the cleaning solution during the cleaning process. The cleaning solution is always in a turbid state, which affects the cleaning effect of the surgical instruments. In addition, the dirt left by the surgical instruments will float on the surface of the cleaning solution and become suspended matter. After the instruments are taken out after cleaning, they are easily contaminated again, which affects the cleaning effect and the efficiency of subsequent processing. Summary of the invention

[0004] The purpose of the present invention is to provide an ultrasonic gastrointestinal surgical instrument cleaning and disinfecting device to solve the defect of insufficient cleaning effect of the existing ultrasonic gastrointestinal surgical instrument cleaning and disinfecting device.

[0006] Preferably, the chain comprises a connecting shaft, a scraper and a toothed disc; the chain is symmetrically distributed about the center line of the cleaning tank, and the inner walls of the shells on both sides of the chain are rotatably connected to the connecting shaft.

[0007] Preferably, both ends of the connecting shaft are fixedly mounted with toothed discs, and the toothed discs and the chain are meshingly connected, and the scraper is fixedly mounted on one end of the chain.

[0008] Preferably, the cleaning tank comprises a water outlet pipe, a connecting pipe and a baffle; the baffle is fixedly arranged on one side of the cleaning tank, the bottom ends of both sides of the baffle are connected to the water outlet pipe, and the bottom end of the cleaning tank is connected to the connecting pipe.

[0009] Preferably, the filtering mechanism includes a water pipe, a water pump and a tank body; the water pump is installed inside the shell, the input end of the water pump is connected to the tank body through a pipe body, the output end of the water pump is connected to the water pipe, and the end of the water pipe away from the water pump extends to the bottom end of the cleaning tank.

[0010] Preferably, the impeller is movably mounted inside the water conduit, and the turbine and the worm are meshingly connected.

[0011] Preferably, the trough body includes a filter plate, a handle and a slide groove; the filter plate is movably installed inside the trough body, two groups of filter plates are provided, and a handle is fixedly installed at one end of the filter plate, slide grooves are provided on both sides of the filter plate, and a sliding structure is formed between the filter plate and the trough body.

[0012] Preferably, the heat dissipation mechanism includes fan blades, an air pipe, a large gear, a small gear and an aeration plate; the fan blade is movably mounted at one end inside the shell, an air inlet hole is provided on the outer wall of the shell at one end of the fan blade, and the inner wall of the shell at the top end of the fan blade is connected to the small gear through a pulley mechanism.

[0013] Preferably, a large gear is rotatably mounted inside the housing at the top end of the pinion gear, and the large gear and the pinion gear are meshingly connected, and one end of the large gear is connected to the connecting shaft through a pulley mechanism.

[0014] Preferably, the air pipe is fixedly arranged on one side of the shell, and an aeration plate is fixedly installed on the inner wall of the cleaning tank at one end of the air pipe.

[0015] The ultrasonic cleaning and disinfecting device for gastrointestinal surgical instruments provided by the present invention has the following advantages:

[0016] By providing a cleaning mechanism, the water pump is started to pump the cleaning liquid being cleaned inside the cleaning tank through the filter plate for filtration. The filter plates are respectively a non-woven filter screen and a polypropylene filter screen. The non-woven filter screen has good air permeability and filtration performance, and the polypropylene filter screen has excellent chemical corrosion resistance, heat resistance and high mechanical strength, and can effectively remove dirt and particulate matter. The filtered cleaning liquid flows to the inside of the cleaning tank through the water guide pipe, so that the cleaning liquid is always in a relatively clean state, and the cleaning effect of the surgical instrument is enhanced. The filter plate and the tank body are slidably connected, and the filter plate can be taken out for cleaning and replacement by pulling the handle, which simplifies the operation, and the connection between the filter plate and the tank body is provided with a sealing gasket to ensure the sealing performance;

[0017] Furthermore, when water flows through the water pipe, it drives the impeller in the pipe to rotate. Through the cooperation of the turbine and the worm, the pulley mechanism drives the connecting shaft to rotate, so that the chain and the scraper fixed at the outer end rotate. When the scraper rotates to the bottom of the chain, it overlaps with the surface of the cleaning liquid, and the suspended matter on the surface can be scraped off from one side to the baffle position, so that when the surgical instrument is taken out after cleaning, the suspended matter can be prevented from sticking and contaminating again, thereby improving the cleaning efficiency.

[0018] By providing a heat dissipation mechanism, a pulley mechanism is connected between the large gear and the connecting shaft. When the connecting shaft rotates, the large gear rotates. The gear differential between the large gear and the small gear enables the high-speed rotation of the fan blades through the pulley mechanism, and the air outside the shell is pumped into the inside. The ultrasonic vibration head is cooled during operation to avoid reducing its working efficiency due to overheating and slowing down the aging of its internal components. The fan installed on the air pipe pumps the hot air in the shell into the aeration plate, generating a large number of bubbles that can stir the cleaning liquid, forming a more complex fluid dynamics environment, and enhancing the cleaning effect.

[0032] Reference Figure 3 , Figure 5 and Fig.10As shown, when the device is used, the surgical instrument is first placed inside the placement net 6, and then the placement net 6 is placed inside the cleaning tank 3, and the cleaning liquid is injected until the baffle 33 is flush with the position, and then the ultrasonic vibration head 7 is started to work, and the signal emitted by the ultrasonic wave is converted into a high-frequency mechanical vibration, which produces a cavitation effect in the cleaning liquid.
