[0015] A usage method of an instrument disinfection device for an operating room is as follows: Step 1: The staff fixes the surgical instruments on the storage rack; Step 2: The residual tissue and blood on the surface of the surgical instruments are cleaned by the cleaning mechanism; Step 3: Use the steam disinfection mechanism to perform high-temperature steam disinfection on surgical instruments; Step 4: Cool down the surgical instruments after steam disinfection so that they can meet the requirement of being quickly retrieved and used again.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the staff manually slides the cover plate to open the upper end of the disinfection box, pushes out the four upper limiting clamping plates outward, compresses the first spring, pushes down the hook plate, hooks the limiting clamping plates to prevent the first spring from pushing them back to their original positions, then places the surgical instruments to be disinfected on the four lower limiting clamping plates in the storage rack, pushes up the hook plate, and the first spring pushes the upper limiting clamping plates back to their original positions. A total of eight limiting clamping plates, four on the upper and lower sides, limit the upper and lower ends of the surgical instruments. Combined with the storage rack, the surgical instruments are limited on the front, back, left, and right sides, facilitating the fixation of the surgical instruments on the storage rack. The provided hook plate is convenient for limiting the four limiting clamping plates, which is conducive to the single-person operation of the staff and saves labor.

[0017] 2. In the present invention, the hydraulic cylinder is started to push the lifting plate downward. The lifting plate drives the support frame to descend. The support frame drives the storage rack and the surgical instruments to descend synchronously until the storage rack drives the movable plate, the hollow shaft, and the top bar to descend to the same horizontal line as the convex block plate and then stops. Then, disinfectant is injected into the bottom of the disinfection box through the liquid inlet pipe, so that the liquid level of the disinfectant submerges the surgical instruments on the storage rack. The disinfectant is convenient for disinfecting the surgical instruments. The driving device two is started to drive the first screw rod to rotate. The first screw rod drives the movable plate to slide to the right. The movable plate drives the hollow shaft, the support plate, the flexible block, and the top bar to slide to the right synchronously. The provided flexible block passes over the upper surface of the surgical instruments, which is beneficial to cleaning the residual tissue and blood on the upper surface of the surgical instruments, ensuring the surface cleanliness of the surgical instruments, and thus ensuring the quality of subsequent steam disinfection of the surgical instruments.

[0018] 3. In the present invention, after the upper surface of the surgical instruments is cleaned, the driving device one is started to drive the storage rack and the surgical instruments to turn over, and then the lower surface of the surgical instruments is cleaned, without the need for manual reassembly and disassembly of the surgical instruments for turning over, which is efficient and fast.

[0019] 4. In the present invention, when the top bar is intermittently blocked by the convex block plate, it will drive the hollow shaft, the support plate, and the flexible block to rotate on the movable plate, compress the torsion spring, and reset under the action of the torsion spring, realizing the reciprocating small-amplitude rotation of the hollow shaft, the support plate, and the flexible block. The multiple provided flexible blocks swing back and forth, which can extend into the irregular dead corners of the surgical instruments for adaptive cleaning of residual tissue and blood, thus being beneficial to ensuring the comprehensive and dead-corner-free cleaning of the surgical instruments, improving the cleaning quality, and ensuring the quality of subsequent steam disinfection of the surgical instruments.

[0020] 5. In the present invention, when the movable plate moves left and right, it will drive the arc-shaped top block to move synchronously. The arc-shaped top block is convenient for squeezing and pushing the two limit clamping plates on both sides to slide away from each other in advance when the flexible block is about to pass through the surface of the surgical instrument, compressing the first spring, so that the flexible block can also clean the area where the limit clamping plates are in contact with the surgical instrument without dead angles, thus ensuring the cleaning quality of the surgical instrument.

[0021] 6. In the present invention, when one of the limit clamping plates is squeezed and moved away, the other limit clamping plate will still clamp the surgical instrument, and will not affect the clamping stability of the surgical instrument.

[0022] 7. In the present invention, when the support frame descends below the liquid level of the disinfectant solution, the disinfectant solution will naturally flow into the hollow tube from the inlet hole. As the hollow shaft rotates back and forth, it will also drive the push block to rotate back and forth, and then push the piston rod to slide backward, compressing the second spring. The piston rod will pass through and exceed the position of the inlet hole, and will pass the disinfectant solution in the hollow tube through the inside of the connecting tube, the hollow shaft and the support plate, and finally spray out from between the flexible blocks. This is beneficial for spraying high-pressure disinfectant solution water on the surface of the surgical instrument when the flexible block brushes the surgical instrument, so as to facilitate the flexible block to clean the tissue and blood on the surface of the surgical instrument with high quality, and improve the quality of subsequent steam disinfection.

[0023] 8. In the present invention, it is also convenient to clean the tissue sandwiched between the flexible blocks, and avoid the situation that the tissue remains in the gap between the flexible blocks for a long time and deteriorates.

[0024] 9. In the present invention, when the hydraulic cylinder is started to drive the support frame and the surgical instrument to rise, the support frame will be blocked by the elastic block and slide on the lifting plate, compressing the third spring. When the elastic block deforms until the support frame can cross over, the third spring drives the support frame to reset, so that the support frame quickly slides on the lifting plate and shakes, which is beneficial to shake off the residual disinfectant solution on the storage rack and the surgical instrument, facilitating subsequent steam disinfection and improving the quality of steam disinfection.

[0025] 10. In the present invention, until the support frame drives the first driving device and the second gear to rise, when the second gear meshes with the first gear, at this time the lifting plate continues to rise, compressing the third spring, so that the third spring is in a tense state, ensuring the meshing stability between the first gear and the second gear.

[0026] 11. In the present invention, the starting steam device sprays steam on the surface of the surgical instruments below through the connecting pipe and the steam nozzle pipe to perform high-temperature disinfection on the surgical instruments. At the same time, the driving device one is started to drive the storage rack and the surgical instruments to rotate, and the gear two drives the gear one to rotate. The gear one drives the screw two to rotate, and the screw two drives the steam nozzle pipe to reciprocate on the lower end of the cover plate, which is beneficial to uniformly spraying the high-temperature steam on both sides of the surgical instruments, improving the quality of high-temperature steam disinfection of the surgical instruments, and ensuring that the surgical instruments can be completely disinfected.

[0027] 12. In the present invention, after the steam disinfection is completed, the cover plate is pushed open, and the blower is started to blow air on the surgical instruments below, which is beneficial to quickly discharging the high-temperature steam in the disinfection box to the outside through the other through port. The internal air of the disinfection box circulates, enabling the surgical instruments to be quickly cooled and dried, preventing the staff from being scalded by the surgical instruments, and improving the efficiency and quality of the staff's reuse of the surgical instruments.

Both the driving device 6 and the second driving device 12 are composed of a driving motor and an external waterproof and heat-insulating shell. The output shafts of the driving motors are respectively fixedly connected to the rotating shaft and the first screw rod 11. The upper and lower ends of the storage rack 5 are symmetrically slidably installed with limiting clamping plates 7 in the left-right, front-back directions. One end of the limiting clamping plate 7 is fixedly installed with a first spring 8, and the other end of the first spring 8 is fixedly installed on the storage rack 5. Hook plates 9 are slidably installed on the storage rack 5 corresponding to the limiting clamping plates 7. Arc-shaped top blocks 13 are fixedly installed on the front and rear sides of the lower end of the movable plate 10 corresponding to the limiting clamping plates 7. A support plate 14 is arranged on the lower side of the movable plate 10. Flexible blocks 15 are fixedly installed at equal intervals at the lower end of the support plate 14. A hollow shaft 16 is fixedly installed in the middle of the upper end of the support plate 14. The upper end of the hollow shaft 16 is rotatably installed through the movable plate 10. A torsion spring 17 is sleeved on the outer side of the hollow shaft 16. A top bar 18 is fixedly installed on the front end of the hollow shaft 16. A convex block plate 19 is fixedly installed corresponding to the top bar 18 on the lower side inside the disinfection box 1. A hollow pipe 20 is fixedly installed at the rear side of the upper end of the movable plate 10. A piston rod 21 is slidably installed through the front end of the hollow pipe 20. A second spring 24 is sleeved on the outer side of the piston rod 21. An inlet hole 22 is opened on the outer side of the hollow pipe 20. A push block 23 is fixedly installed on the rear end of the hollow shaft 16 corresponding to the piston rod 21. A connecting pipe 25 is communicated with the rear side of the hollow pipe 20. The other end of the connecting pipe 25 is fixedly communicated with the inside of the hollow shaft 16. An air passage is opened inside the support plate 14, and the outlets of the air passage are respectively arranged between the flexible blocks 15. The hollow pipe 20, the connecting pipe 25, the hollow shaft 16 and the inside of the air passage are mutually communicated; During operation, the staff manually slide the cover plate 30 to open the upper end of the disinfection box 1, push the four upper limiting clamping plates 7 outwards, compress the first spring 8, push the hook plate 9 downwards to hook the limiting clamping plate 7 and prevent the first spring 8 from pushing it back to its original position. Then, place the surgical instruments to be disinfected on the four lower limiting clamping plates 7 in the storage rack 5, push the hook plate 9 upwards, and the first spring 8 pushes the upper limiting clamping plate 7 back to its original position. A total of eight limiting clamping plates 7, four on the upper and lower sides, limit the upper and lower ends of the surgical instruments, and together with the storage rack 5, limit the surgical instruments on the front, back, left, and right sides, facilitating the fixation of the surgical instruments on the storage rack 5. The set hook plate 9 facilitates the limitation of the four limiting clamping plates 7, which is conducive to the single-person operation of the staff, saving labor. Cover the cover plate 30, start the hydraulic cylinder 28 to push the lifting plate 26 downwards. The lifting plate 26 drives the support frame 4 to descend, and the support frame 4 drives the storage rack 5 and the surgical instruments to descend synchronously until the storage rack 5 drives the movable plate 10, the hollow shaft 16, and the top strip 18 to descend to the same horizontal line as the convex block plate 19 and then stop. Then, inject the disinfectant into the bottom of the disinfection box 1 through the liquid inlet pipe 2, so that the liquid level of the disinfectant submerges the surgical instruments on the storage rack 5, facilitating the disinfection of the surgical instruments by the disinfectant. Start the second driving device 12 to drive the first screw rod 11 to rotate. The first screw rod 11 drives the movable plate 10 to slide to the right. The movable plate 10 drives the hollow shaft 16, the support plate 14, the flexible block 15, and the top strip 18 to slide to the right synchronously. The set flexible block 15 passes over the upper surface of the surgical instruments, which is conducive to cleaning the residual tissue and blood on the upper surface of the surgical instruments, ensuring the surface cleanliness of the surgical instruments, and thus ensuring the quality of subsequent steam disinfection of the surgical instruments. When the cleaning of the upper surface of the surgical instruments is completed, start the first driving device 6 to drive the storage rack 5 and the surgical instruments to turn over, and then clean the lower surface of the surgical instruments, without the need for manual reassembly and disassembly of the surgical instruments for turning over, which is efficient and fast. When the top strip 18 is intermittently blocked by the convex block plate 19, it will drive the hollow shaft 16, the support plate 14, and the flexible block 15 to rotate on the movable plate 10, compress the torsion spring 17, and reset under the action of the torsion spring 17, realizing the reciprocating small-amplitude rotation of the hollow shaft 16, the support plate 14, and the flexible block 15. The set multiple flexible blocks 15 swing back and forth, which can extend into the irregular dead corners of the surgical instruments for adaptive cleaning of residual tissue and blood, thus being conducive to ensuring the comprehensive and non-dead-angle cleaning of the surgical instruments, improving the cleaning quality, and ensuring the quality of subsequent steam disinfection of the surgical instruments. Moreover, when the movable plate 10 moves left and right, it will drive the arc-shaped top block 13 to move synchronously. The arc-shaped top block 13 is convenient for squeezing and pushing the two side limiting clamping plates 7 to slide away from each other in advance when the flexible block 15 is about to pass over the surface of the surgical instruments, compressing the first spring 8, so as to facilitate the flexible block 15 to also clean the area where the limiting clamping plate 7 abuts and fits on the surgical instruments without dead angles, thus ensuring the cleaning quality of the surgical instruments. And when one side of the limiting clamping plate 7 is squeezed away, the other side of the limiting clamping plate 7 will still clamp the surgical instruments.It does not affect the clamping stability of the surgical instrument. When the support frame 4 drops below the level of the disinfectant, the disinfectant will naturally flow into the hollow tube 20 from the inlet hole 22. As the hollow shaft 16 reciprocates, it will also drive the push block 23 to reciprocate, thereby pushing the piston rod 21 to slide backward and compress the spring 24. The piston rod 21 will pass through and exceed the inlet hole 22, and the disinfectant in the hollow tube 20 will pass through the connecting tube 25, the hollow shaft 16 and the inside of the support plate 14, and finally be ejected from between the flexible blocks 15. When the flexible block 15 is brushed off the surgical instrument, the surface of the surgical instrument is sprayed with a high-pressure disinfectant water flow, thereby facilitating the flexible block 15 to clean the tissue and blood on the surface of the surgical instrument with high quality, improving the quality of subsequent steam disinfection, and also facilitating the cleaning of the tissue sandwiched between the flexible blocks 15, so as to avoid the tissue remaining in the gap between the flexible blocks 15 for a long time, causing deterioration.

[0032] As an embodiment of the present invention, a steam sterilization mechanism for steam sterilizing surgical instruments is also provided, the steam sterilization mechanism includes a lifting plate 26 slidably mounted on the rear end of the support frame 4, a hydraulic cylinder 28 is fixedly mounted on the upper end of the lifting plate 26, the hydraulic cylinder 28 is fixedly mounted on the upper end of the disinfection box 1, a spring 3 27 is fixedly mounted on the upper end of the lifting plate 26, the upper end of the spring 3 27 is fixedly mounted on the support frame 4, and an elastic block 29 is fixedly mounted on the bottom of the disinfection box 1 corresponding to the support frame 4, a through opening is opened on the lifting plate 26 corresponding to the elastic block 29, a cover plate 30 is slidably mounted on the upper end of the disinfection box 1, and a cover plate 30 is slidably mounted on the left side of the lower end of the cover plate 30 A steam nozzle pipe 31, a screw rod 32 is threadedly installed on the middle part of the steam nozzle pipe 31, and the screw rod 32 is rotatably installed on the cover plate 30. A gear rod 33 is fixedly installed on the right side of the screw rod 32, and a gear rod 34 is fixedly installed on the output shaft of the left end of the driving device 6 corresponding to the gear rod 33. A connecting pipe 35 is fixedly connected on the right side of the steam nozzle pipe 31, and a steam device 36 is connected at the other end of the connecting pipe 35. The steam device 36 is fixedly installed on the upper end of the cover plate 30. Through holes 37 are opened on both sides of the cover plate 30, and a fan 38 is fixedly installed in the through hole 37 on the right side. A sealing plate 39 is slidably installed on the upper end of the cover plate 30 corresponding to the through hole 37; During operation, open the solenoid valve on the drain pipe 3 to discharge the disinfected solution mixed with tissue blood outside the disinfection box 1. Start the hydraulic cylinder 28 to drive the support frame 4 and the surgical instruments to rise. The support frame 4 will be blocked by the elastic block 29 and slide on the lifting plate 26, compressing the third spring 27. When the elastic block 29 deforms until the support frame 4 can cross over, the third spring 27 drives the support frame 4 to reset, causing the support frame 4 to slide rapidly on the lifting plate 26 and vibrate, which is conducive to shaking off the residual disinfected solution on the storage rack 5 and the surgical instruments, facilitating subsequent steam disinfection and improving the quality of steam disinfection. Until the support frame 4 drives the first driving device 6 and the second gear 34 to rise, when the second gear 34 meshes with the first gear 33, at this time the lifting plate 26 continues to rise, compressing the third spring 27 to make the third spring 27 in a tense state, ensuring the stability of the meshing between the first gear 33 and the second gear 34. Start the steam device 36 to spray steam on the surface of the lower surgical instruments through the connecting pipe 35 and the steam nozzle pipe 31 for high-temperature disinfection of the surgical instruments. At the same time, start the first driving device 6 to drive the storage rack 5 and the surgical instruments to rotate, and the second gear 34 drives the first gear 33 to rotate. The first gear 33 drives the second screw 32 to rotate, and the second screw 32 drives the steam nozzle pipe 31 to slide reciprocally under the cover plate 30, which is conducive to evenly spraying the high-temperature steam on both sides of the surgical instruments, improving the quality of high-temperature steam disinfection of the surgical instruments and ensuring that the surgical instruments can be completely disinfected. After the steam disinfection is completed, push open the cover plate 39 and start the blower 38 to blow air on the lower surgical instruments, which is conducive to quickly discharging the high-temperature steam in the disinfection box 1 from the other through port 37 to the outside. The air inside the disinfection box 1 circulates, enabling the surgical instruments to cool down and dry quickly, so that the staff will not be scalded by the surgical instruments, and improving the efficiency and quality of the staff to pick up the surgical instruments again.

[0033] A method for using an instrument disinfection device for an operating room is as follows: Step 1: The staff fix the surgical instruments on the storage rack 5. Step 2: Clean the residual tissue and blood on the surface of the surgical instruments through the cleaning mechanism. Step 3: Disinfect the surgical instruments with high-temperature steam through the steam disinfection mechanism. Step 4: Cool down the surgical instruments after steam disinfection so that they can meet the requirement of being quickly picked up and used again.

[0034] Working principle: When the present invention is in use, the staff manually slides the cover plate 30 to open the upper end of the disinfection box 1, pushes the four upper limiting clamping plates 7 outwards, compresses the first spring 8, pushes the hook plate 9 downwards, hooks the limiting clamping plate 7, and prevents the first spring 8 from pushing it back to its original position. Then, the surgical instruments to be disinfected are placed on the four lower limiting clamping plates 7 in the storage rack 5. The hook plate 9 is pushed upwards, and the first spring 8 pushes the upper limiting clamping plate 7 back to its original position. A total of eight limiting clamping plates 7, four on the upper and lower sides, limit the upper and lower ends of the surgical instruments. Combined with the storage rack 5, the surgical instruments are limited in the front, back, left, and right directions, facilitating the fixation of the surgical instruments on the storage rack 5. The set hook plate 9 is convenient for limiting the four limiting clamping plates 7, which is beneficial for the single-person operation of the staff, saving labor. The cover plate 30 is covered, and the hydraulic cylinder 28 is started to push the lifting plate 26 downwards. The lifting plate 26 drives the support frame 4 to descend. The support frame 4 drives the storage rack 5 and the surgical instruments to descend synchronously until the storage rack 5 drives the movable plate 10, the hollow shaft 16, and the top strip 18 to descend to the same horizontal line as the convex block plate 19 and then stops. Then, the disinfectant is injected into the bottom of the disinfection box 1 through the liquid inlet pipe 2, so that the liquid level of the disinfectant submerges the surgical instruments on the storage rack 5. The disinfectant is convenient for disinfecting the surgical instruments. The driving device two 12 is started to drive the first screw rod 11 to rotate. The first screw rod 11 drives the movable plate 10 to slide to the right. The movable plate 10 drives the hollow shaft 16, the support plate 14, the flexible block 15, and the top strip 18 to slide to the right synchronously. The set flexible block 15 passes through the upper surface of the surgical instrument, which is beneficial for cleaning the residual tissue and blood on the upper surface of the surgical instrument, ensuring the surface cleanliness of the surgical instrument, and thus ensuring the quality of subsequent steam disinfection of the surgical instrument. When the upper surface of the surgical instrument is cleaned, the driving device one 6 is started to drive the storage rack 5 and the surgical instruments to turn over, and then the lower surface of the surgical instrument is cleaned. There is no need for manual disassembly and reassembly of the surgical instruments to turn them over, which is efficient and fast. When the top strip 18 is intermittently blocked by the convex block plate 19, it will drive the hollow shaft 16, the support plate 14, and the flexible block 15 to rotate on the movable plate 10, compress the torsion spring 17, and reset under the action of the torsion spring 17, realizing the reciprocating small-amplitude rotation of the hollow shaft 16, the support plate 14, and the flexible block 15. The set multiple flexible blocks 15 swing back and forth, and can extend into the irregular dead corners of the surgical instrument to adaptively clean the residual tissue and blood, which is beneficial for ensuring the comprehensive and dead-corner-free cleaning of the surgical instrument, improving the cleaning quality, and ensuring the quality of subsequent steam disinfection of the surgical instrument. Moreover, when the movable plate 10 moves left and right, it will drive the arc-shaped top block 13 to move synchronously. The arc-shaped top block 13 is convenient for squeezing and pushing the two side limiting clamping plates 7 to slide away from each other in advance when the flexible block 15 is about to pass through the surface of the surgical instrument, compressing the first spring 8, so that the flexible block 15 can also clean the area where the limiting clamping plate 7 abuts and fits on the surgical instrument without dead corners, thus ensuring the cleaning quality of the surgical instrument. When one side of the limiting clamping plate 7 is squeezed and moved away, the other side of the limiting clamping plate 7 will still clamp the surgical instrument.It will not affect the clamping stability of the surgical instrument. When the support frame 4 descends below the liquid level of the disinfectant solution, the disinfectant solution will naturally flow into the hollow tube 20 from the inlet hole 22. As the hollow shaft 16 rotates reciprocally, it will also drive the push block 23 to rotate reciprocally, thereby pushing the piston rod 21 to slide backward, compressing the second spring 24. The piston rod 21 will pass through and exceed the position of the inlet hole 22, and the disinfectant solution in the hollow tube 20 will pass through the inside of the connecting tube 25, the hollow shaft 16, and the support plate 14, and finally spray out between the flexible blocks 15. This is beneficial for spraying high-pressure disinfectant solution water on the surface of the surgical instrument when the flexible blocks 15 brush the surgical instrument, so as to facilitate the flexible blocks 15 to clean the tissue and blood on the surface of the surgical instrument with high quality, improve the quality of subsequent steam disinfection, and at the same time facilitate the cleaning of the tissue sandwiched between the flexible blocks 15, avoiding the situation of tissue deterioration due to long-term retention in the gap between the flexible blocks 15. After completion, open the solenoid valve on the drain pipe 3 to discharge the disinfectant solution mixed with tissue blood outside the disinfection box 1. Start the hydraulic cylinder 28 to drive the support frame 4 and the surgical instrument to rise. The support frame 4 will be blocked by the elastic block 29 and slide on the lifting plate 26, compressing the third spring 27. When the elastic block 29 deforms to the point where the support frame 4 can pass over, the third spring 27 drives the support frame 4 to reset, causing the support frame 4 to slide rapidly on the lifting plate 26 and vibrate, which is beneficial for shaking off the remaining disinfectant solution on the storage rack 5 and the surgical instrument, facilitating subsequent steam disinfection and improving the quality of steam disinfection. Until the support frame 4 drives the first driving device 6 and the second gear 34 to rise, when the second gear 34 meshes with the first gear 33, at this time the lifting plate 26 continues to rise, compressing the third spring 27, making the third spring 27 in a taut state to ensure the meshing stability between the first gear 33 and the second gear 34. Start the steam device 36 to spray steam on the surface of the surgical instrument below through the communication pipe 35 and the steam nozzle pipe 31 for high-temperature disinfection of the surgical instrument. At the same time, start the first driving device 6 to drive the storage rack 5 and the surgical instrument to rotate, and the second gear 34 drives the first gear 33 to rotate. The first gear 33 drives the second screw 32 to rotate, and the second screw 32 drives the steam nozzle pipe 31 to slide reciprocally on the lower end of the cover plate 30, which is beneficial for evenly spraying the high-temperature steam on both sides of the surgical instrument, improving the quality of high-temperature steam disinfection of the surgical instrument and ensuring that the surgical instrument can be completely disinfected. After the steam disinfection is completed, push open the cover plate 39 and start the fan 38 to blow air on the surgical instrument below, which is beneficial for quickly discharging the high-temperature steam in the disinfection box 1 from the other through hole 37 to the outside. The air circulation inside the disinfection box 1 can quickly cool and dry the surgical instrument, so that the staff will not be scalded by the surgical instrument, improving the efficiency and quality of the staff's subsequent access to the surgical instrument.,
