Sterilization device for surgical instruments

Abstract

A sterilization and disinfection device for surgical instruments, belonging to the field of surgical instrument disinfection, includes a sterilization chamber, a liquid supply device, and a drying device. The liquid supply device is installed on one outer wall of the sterilization chamber, and the drying device is installed on the top of the sterilization chamber. When sterilizing scissors, the invention closes the chamber door, and a sliding column and guide rod work together to raise a protrusion that engages with the gap between the scissors, separating and fixing the scissors, eliminating the contact surface, blocking pathogens, and preventing collision and wear. Simultaneously, it moves the placement crossbar downwards. Through a connecting frame and a lifting plate, the placement crossbar is moved closer and further apart in an arc shape under the action of a tension spring, achieving blade separation and merging, ensuring thorough sterilization and removing residual biofilm. Furthermore, the placement crossbar is mechanically decoupled when the chamber door is not closed, avoiding the risk of misoperation. In addition, the placement crossbar tilts accordingly when the chamber door is opened and closed, facilitating "zero-contact" grasping by medical personnel and accurate subsequent fixing of the protrusion.

Description

Technical Field

[0001] This invention relates to the field of surgical instrument disinfection technology, and in particular to a surgical instrument sterilization and disinfection device. Background Technology

[0002] During the surgical procedure, a number of medical instruments are used to assist patients. In order to ensure the hygiene and safety of the operation, the medical instruments need to be cleaned, disinfected and sterilized before the operation to prevent residual bacteria from causing infection and other problems to the patient. Commonly used surgical instruments include knives, scissors, needles, forceps, clamps and hooks. The structure of scissors is different from the other tools, and the sterilization method should also be different.

[0003] Currently, when using sterilization devices to disinfect surgical scissors, it is usually necessary to place several scissors in the device for immersion and disinfection simultaneously. When multiple scissors are stacked and soaked, pathogenic microorganisms remaining in the crevices of the blades are prone to cross-adhesion, increasing the difficulty of cleaning and leading to incomplete disinfection. This increases the risk of secondary infection for patients. Furthermore, the lever effect of the hinge structure of the scissors causes the blades to naturally adhere in a static state, forming a closed area. This prevents the disinfectant from penetrating due to surface tension, and the disinfectant only penetrates through diffusion. The fluid exchange rate in the closed area is low, and manually opening the blades for cleaning is time-consuming and inconsistent, failing to meet the high-efficiency requirements of the daily processing volume of surgical instruments. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where residue easily remains in the blade crevices, resulting in inadequate disinfection, and the difficulty in meeting the high-efficiency requirements of the daily processing volume of surgical instruments. Therefore, a surgical instrument sterilization and disinfection device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sterilization and disinfection device for surgical instruments includes a sterilization chamber, a liquid supply device, and a drying device. The liquid supply device is installed on one outer wall of the sterilization chamber, and the drying device is installed on the top of the sterilization chamber. An operation window is provided on the front outer wall of the sterilization chamber, and a door is slidably installed on the front inner wall of the sterilization chamber corresponding to the operation window. A sliding groove is provided on the rear inner wall of the sterilization chamber.

[0007] The inner wall of the chute is provided with staggered protrusions to allow the door to be lowered and engaged in the gap between adjacent scissors for separation and fixation, laying the foundation for thorough disinfection and realizing mechanical interlocking movement.

[0008] The rear inner wall of the disinfection box is equipped with an interlocking opening and closing component, which can drive the blades to separate and merge after mechanical interlocking. This can both open the blades to ensure the comprehensiveness of disinfection and sterilization, and use the shearing force friction generated by the closing of the scissor blades to peel off the biofilm adhering to the blade surface.

[0009] The disinfection box is equipped with a bidirectional tilting component to control the tilt angle before and after lifting, which makes it convenient for medical staff to grab the scissors and enables accurate separation and fixation of the scissors afterward.

[0010] Furthermore, the staggered protrusion component includes a limiting block, and the outer wall of the limiting block is slidably connected to the inner wall of the slide groove. The inner wall of the slide groove is T-shaped. A connecting rod is fixedly connected to the top of the slide groove, and the other end of the connecting rod is fixedly connected to the outer wall of the door facing the limiting block. A shaft is fixedly connected to the side of the limiting block facing the door, and two hinge rods are hinged to the outer wall of the shaft. A movable groove is opened through the top side wall of the two hinge rods, and a rotating column is symmetrically rotatably connected to the inner wall of the movable groove. A placement crossbar is fixedly connected to the end of the two rotating columns that are close to each other. A threaded column is fixedly connected to the end of the placement crossbar facing the operation window, and a blocking handle is threadedly connected to the outer wall of the threaded column. A rotating rod is provided inside the placement crossbar, and the end of the rotating rod facing the operation window is rotatably connected to the end of the threaded column.

[0011] Furthermore, a universal joint is installed at the end of the rotating rod away from the threaded column, and a connecting rod two is movably installed at the end of the rotating rod away from the threaded column via the universal joint. A sliding plate is slidably connected to the outer wall of the connecting rod two, and a rotary groove is opened on the outer wall of the connecting rod two. A ball is fixedly connected to the inner wall of the sliding plate corresponding to the rotary groove, and the outer wall of the ball is slidably connected to the inner wall of the rotary groove. A sliding column is fixedly connected to the upper side of the end face of the sliding plate away from the rotating rod.

[0012] Furthermore, the rear inner wall of the disinfection box is symmetrically provided with grooves corresponding to the sliding column, and a guide rod is fixedly connected to the inner wall of the groove. The outer wall of the sliding column slides and matches the inner wall of the groove. The upper part of the guide rod is a long low surface, the middle part of the guide rod is a short high surface, and the lower part of the guide rod is a high arc surface.

[0013] Furthermore, the outer wall of the rotating rod is symmetrically and fixedly connected with protrusions, the inner wall of the crossbar is symmetrically and equidistantly provided with mounting grooves, the outer wall of the rotating rod is symmetrically and equidistantly provided with mounting blocks corresponding to the mounting grooves, and the top of the mounting block is fixedly connected with a spring, the other end of the spring is fixedly connected to the inner wall of the mounting groove, the top of the mounting block is fixedly connected with a protrusion, the inner wall of the mounting groove is provided with a through hole corresponding to the protrusion, and the top of the protrusion is inclined.

[0014] Furthermore, the interlocking opening and closing component includes a drive motor, one side of which is fixedly installed on the rear outer wall of the disinfection box. A cam is fixedly connected to one end of the output shaft of the drive motor. A fixing block is fixedly connected to the rear inner wall of the disinfection box, and a reciprocating rod is slidably connected to the inner wall of the fixing block. The bottom of the reciprocating rod is slidably connected to the outer wall of the cam. Limiting grooves are formed through the bottom side walls of the two hinged rods, and a connecting frame is slidably connected to the inner wall of the limiting grooves.

[0015] Furthermore, tension springs are fixedly connected to the bottom sidewalls of both hinge rods, and a lifting plate is fixedly connected to the top of the reciprocating rod corresponding to the connecting frame.

[0016] Furthermore, the bidirectional tilting component includes a support block, the bottom of which is fixedly connected to the inner wall of the bottom of the movable groove. A push rod is slidably connected to the inner wall of the support block, and one end of the push rod is fixedly connected to the lower side of the end face of the slide plate facing the operation window. A lifting block is attached to the end of the push rod away from the slide plate, and the top of the lifting block is attached to the lower surface of the placement crossbar. Slider blocks are fixedly connected to the outer walls of both ends of the lifting block. Inclined grooves are symmetrically opened on the inner wall of the movable groove corresponding to the sliders, and the outer wall of the slider is slidably connected to the inner wall of the inclined groove.

[0017] Compared with existing technologies, the above solution has the following advantages:

[0018] 1. When disinfecting scissors, the device can place the end rings of several scissors separately using two horizontal bars. Simultaneously, when the door is closed, the sliding column and guide rod work together to raise several protrusions synchronously, automatically fitting into the gaps between adjacent scissors. This automatically separates and secures the scissors on the horizontal bars, completely eliminating contact surfaces between instruments, preventing cross-adhesion of pathogens, and avoiding collisions and wear during subsequent disinfection. This lays the foundation for thorough disinfection and sterilization, thus helping to ensure the disinfection effect of this device.

[0019] 2. When disinfecting scissors, the two hinged placement crossbars can be moved down a certain distance simultaneously when the cabinet door is closed. Through the cooperation of the connecting frame and the lifting plate, and driven by the tension spring, the two placement crossbars can be separated and brought closer together in an arc shape at their current positions. This achieves the separation and merging of the blades during several scissor immersion disinfection processes. It can both open the blades to ensure comprehensive disinfection and sterilization, and use the shearing force friction generated by the closing of the scissor blades to peel off the biofilm adhering to the blade surface, avoiding stubborn dirt on the blade surface, thus helping to ensure the disinfection effect of this disinfection device.

[0020] Furthermore, when the door is not closed, the horizontal bar does not move down, thus being in a mechanically decoupled state. This prevents accidental opening of the interlocking opening and closing components, which could cause injury to medical staff by opening and closing several scissors. It completely avoids the risk of misoperation and helps to improve the protective effect of this disinfection device.

[0021] 3. When disinfecting scissor instruments, during the opening of the box door after disinfection, the lifting block and push rod can be used to tilt the end of the horizontal bar near the box door slightly downwards as it moves upwards. This allows the instruments to slide towards the box door under the influence of gravity, enabling medical staff to grasp them with "zero contact," reducing the probability of hand contamination and meeting the high-efficiency requirements of the daily processing volume of surgical instruments.

[0022] When the box door is closed, the horizontal bar will move down synchronously and tilt slightly upward, allowing several scissors to move to the side away from the box door under the action of gravity. This allows the position and orientation of the scissors to be reconfirmed, ensuring they are close to each other and vertically downward. This ensures accurate fixation of the subsequent protrusions, making it easier for them to accurately insert into the gaps between the scissors when they are raised, thus avoiding unexpected situations that could lead to separation failure.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order, or relative importance between these entities or operations.

[0034] Example 1, referring to Figures 1-8 A surgical instrument sterilization and disinfection device includes a sterilization chamber 1, a liquid supply device 2, and a drying device 3. The liquid supply device 2 is installed on one outer wall of the sterilization chamber 1, and the drying device 3 is installed on the top of the sterilization chamber 1. An operation window 4 is provided on the front outer wall of the sterilization chamber 1, and a door 5 is slidably installed on the front inner wall of the sterilization chamber 1 corresponding to the operation window 4. A sliding groove 6 is provided on the rear inner wall of the sterilization chamber 1.

[0035] The inner wall of the slide 6 is provided with a protrusion offset component 7, which includes a limiting block 701. The outer wall of the limiting block 701 is slidably connected to the inner wall of the slide 6. The inner wall of the slide 6 is T-shaped. A connecting rod 10 is fixedly connected to the top of the slide 6, and the other end of the connecting rod 10 is fixedly connected to the outer wall of the door 5 facing the limiting block 701. A shaft post 702 is fixedly connected to the side of the limiting block 701 facing the door 5, and two hinge rods 703 are hinged to the outer wall of the shaft post 702. The top sidewall of 03 is provided with a movable groove 704, and the inner wall of the movable groove 704 is symmetrically rotatably connected with rotating columns 705. The two rotating columns 705 are fixedly connected to a placement crossbar 706 at one end that is close to each other. The end of the placement crossbar 706 facing the operation window 4 is fixedly connected with a threaded column 707, and the outer wall of the threaded column 707 is threadedly connected with a blocking handle 708. The interior of the placement crossbar 706 is provided with a rotating rod 709, and the end of the rotating rod 709 facing the operation window 4 is rotatably connected to one end of the threaded column 707.

[0036] In this embodiment, when the device is used, the box door 5 is first opened, and then the end rings of several scissors are inserted into the outer surface of two placement crossbars 706 in sequence. Then, a threaded post 707 is fixedly connected to one end of the placement crossbar 706 facing the operation window 4, and a blocking handle 708 is threadedly connected to the outer wall of the threaded post 707. Thus, after the scissors are loaded, the blocking handle 708 is screwed into the threaded post 707 to block the loaded scissors from falling off.

[0037] Next, the door 5 is closed. The outer wall of the limiting block 701 slides against the inner wall of the slide groove 6. The inner wall of the slide groove 6 is T-shaped. A connecting rod 10 is fixedly connected to the top of the slide groove 6, and the other end of the connecting rod 10 is fixedly connected to the outer wall of the door 5 facing the limiting block 701. A shaft 702 is fixedly connected to the side of the limiting block 701 facing the door 5. Two hinge rods 703 are hinged to the outer wall of the shaft 702. A movable groove 704 is formed through the top sidewall of the two hinge rods 703, and the inner wall of the movable groove 704 is symmetrically rotatably connected to... The rotating column 705 has two rotating columns 705 with one end of each column close to the other fixedly connected to a horizontal bar 706. This allows the two horizontal bars 706 to be lowered synchronously via the connecting rod 10. The liquid supply device 2 is installed on one side of the outer wall of the disinfection box 1, and the drying device 3 is installed on the top of the disinfection box 1. After the box door 5 is closed, the liquid supply device 2 sends disinfectant into the disinfection box 1 to soak and disinfect several scissors that are loaded. After the disinfection is completed and the disinfectant is discharged, the scissors can be dried by the drying device 3 on the top.

[0038] Next, during the descent of the two horizontal bars 706, a universal joint 710 is installed at the end of the rotating rod 709 away from the threaded post 707, and a connecting rod 711 is movably installed at the end of the rotating rod 709 away from the threaded post 707 via the universal joint 710. A sliding plate 712 is slidably connected to the outer wall of the connecting rod 711, and a rotary groove 713 is formed on the outer wall of the connecting rod 711. A ball bearing 714 is fixedly connected to the inner wall of the sliding plate 712 corresponding to the rotary groove 713, and the outer wall of the ball bearing 714 is slidably connected to the inner wall of the rotary groove 713. A sliding column 715 is fixedly connected to the upper side of the end face of the sliding plate 712 away from the rotating rod 709. A groove 11 is symmetrically opened on the inner wall of the rear side of the disinfection box 1 corresponding to the sliding column 715, and a guide rod 12 is fixedly connected to the inner wall of the groove 11. The outer wall of the sliding column 715 slides and matches the inner wall of the groove 11. The upper part of the guide rod 12 is a long low surface, the middle part of the guide rod 12 is a short high surface, and the lower part of the guide rod 12 is a high arc surface. Thus, in the normal state, that is, when the box door 5 has not yet descended, the sliding column 715 will be located on the upper long low surface of the guide rod 12.

[0039] When the door 5 is closed, based on the ratio of the long lower surface to the short higher surface, it can be seen that when the door 5 is almost completely closed, the sliding column 715 can slide from the long lower surface into the short higher surface, so that the sliding column 715 will drive the sliding plate 712 to slide on the surface of the connecting rod 711. At this time, through the cooperation of the ball 714 and the rotary groove 713, the connecting rod 711 will synchronously drive the rotating rod 709 to rotate through the universal joint 710.

[0040] Next, convex strips 716 are symmetrically fixedly connected to the outer wall of the rotating rod 709. The inner wall of the horizontal bar 706 is symmetrically and equidistantly provided with mounting grooves 717. Mounting blocks 718 are symmetrically and equidistantly provided on the outer wall of the rotating rod 709 corresponding to the mounting grooves 717. A spring 719 is fixedly connected to the top of each mounting block 718, and the other end of the spring 719 is fixedly connected to the inner wall of the mounting groove 717. A protrusion 720 is fixedly connected to the top of each mounting block 718. A through hole 721 is provided on the inner wall of the mounting groove 717 corresponding to the protrusion 720, and the top of the protrusion 720 is beveled. Therefore, when the rotating rod 709 rotates 90 degrees, the convex strips 716 can simultaneously... Several mounting blocks 718 symmetrically arranged vertically within the horizontal bar 706 are compressed, causing them to retract into the mounting groove 717 and compress the spring 719. This allows the protrusions 720 to simultaneously extend from the through holes 721 through the engagement of the protrusions 720 and the through holes 721, automatically embedding themselves into the gaps between adjacent scissors. This automatically separates and fixes several scissors on the horizontal bar 706, completely eliminating the contact surface between adjacent instruments, preventing cross-adhesion of pathogens, and avoiding collisions and wear during subsequent disinfection. This lays the foundation for thorough disinfection and sterilization, thus helping to ensure the disinfection effect of this disinfection device.

[0041] Next, the interlocking opening and closing component 8 includes a drive motor 801, and one side of the drive motor 801 is fixedly installed on the rear outer wall of the disinfection box 1. One end of the drive motor 801 output shaft is fixedly connected to a cam 802. A fixing block 803 is fixedly connected to the rear inner wall of the disinfection box 1. A reciprocating rod 804 is slidably connected to the inner wall of the fixing block 803. The bottom of the reciprocating rod 804 is slidably connected to the outer wall of the cam 802. A limit groove 805 is opened through the bottom side wall of the two hinge rods 703. A connecting frame 806 is slidably connected to the inner wall of the limit groove 805.

[0042] In this embodiment, when the door 5 is fully closed, several protrusions 720 separate and fix several scissors. At this time, the sliding column 715 slides into the junction of the short, high surface and the high arc surface, and the bottom of the connecting frame 806 contacts the lifting plate 808. A cam 802 is fixedly connected to one end of the output shaft of the drive motor 801. A fixing block 803 is fixedly connected to the rear inner wall of the disinfection box 1, and a reciprocating rod 804 is slidably connected to the inner wall of the fixing block 803. The bottom of the reciprocating rod 804 is slidably connected to the protrusions 720. The outer wall of wheel 802 has a limiting groove 805 through the bottom side wall of the two hinge rods 703, and the inner wall of the limiting groove 805 is slidably connected to the connecting frame 806. The bottom side wall of the two hinge rods 703 is fixedly connected to a tension spring 807. The top of the reciprocating rod 804 is fixedly connected to the connecting frame 806 with a lifting plate 808. Under normal conditions, the intersecting angle of the two hinge rods 703 is controlled by the elastic force of the tension spring 807, that is, the elastic force of the tension spring 807 can be used to pull the two sliding columns 715 to keep them at the junction of the short high surface and the high arc surface.

[0043] At this time, the drive motor 801 drives the cam 802 to rotate, which in turn drives the lifting plate 808 to squeeze and lift the connecting frame 806. With the cooperation of the limiting groove 805, when the connecting frame 806 rises, the sliding column 715 cooperates with the high arc surface to make the two placement crossbars 706 separate in an arc shape. Then, the tension spring 807 drives the two sliding columns 715 back to the junction position of the short high surface and the high arc surface. This realizes the separation and merging of the blades in several scissor soaking and disinfection processes. It can open the blades to ensure the comprehensiveness of disinfection and sterilization, and use the shearing force friction generated by the closing of the scissor blades to peel off the biofilm adhering to the blade surface, avoiding the presence of stubborn dirt on the blade surface, thus helping to ensure the disinfection effect of this disinfection device.

[0044] Furthermore, after the disinfection soaking is completed and the disinfectant solution is drained, the scissors can continue to open and close while still being dried, which facilitates thorough drying of the scissors.

[0045] Furthermore, when the door 5 is not closed, the horizontal bar 706 does not move down, thus being in a mechanically decoupled state. That is, there is a certain distance between the connecting frame 806 and the lifting plate 808. This can prevent the interlocking opening and closing component 8 from being accidentally opened, which could cause several scissors to open and close and cause injury to medical staff. This completely avoids the risk of misoperation and helps to improve the protective effect of this disinfection device.

[0046] The bidirectional tilting component 9 includes a support block 901, the bottom of which is fixedly connected to the bottom inner wall of the movable groove 704. A push rod 902 is slidably connected to the inner wall of the support block 901, and one end of the push rod 902 is fixedly connected to the lower side of the end face of the slide plate 712 facing the operation window 4. A lifting block 903 is attached to the end of the push rod 902 away from the slide plate 712, and the top of the lifting block 903 is attached to the lower surface of the crossbar 706. Slider blocks 904 are fixedly connected to the outer walls of both ends of the lifting block 903. An inclined groove 905 is symmetrically opened on the inner wall of the movable groove 704 corresponding to the slider 904, and the outer wall of the slider 904 is slidably connected to the inner wall of the inclined groove 905.

[0047] In this embodiment, the horizontal bar 706 is deflected at an angle around the rotating column 705. When the door 5 is open, the sliding column 715 should be located at the lower long surface. At this time, the bottom of the support block 901 is fixedly connected to the bottom inner wall of the movable groove 704. The inner wall of the support block 901 is slidably connected to the push rod 902, and one end of the push rod 902 is fixedly connected to the lower side of the end face of the sliding plate 712 facing the operation window 4. The end of the push rod 902 away from the sliding plate 712 is fitted with a lifting block 903. The top of 903 fits against the lower surface of the placement crossbar 706, thereby supporting and restricting the slide plate 712 and the connecting rod 711 through the cooperation of the support block 901 and the push rod 902. The lifting block 903 controls the current angle of the two placement crossbars 706, so that the end near the box door 5 is slightly tilted downward. Under the action of gravity, the instrument slides towards the box door 5, allowing medical staff to grasp it with "zero contact", reducing the probability of hand contamination and meeting the high efficiency requirements of the daily processing volume of surgical instruments.

[0048] Similarly, when the door 5 is closed, the slide plate 712 will move towards the door 5, thereby synchronously driving the push rod 902 to push the lifting block 903. At this time, the slider 904 is fixedly connected to the outer walls of both ends of the lifting block 903. The inner wall of the movable groove 704 is symmetrically provided with inclined grooves 905 corresponding to the slider 904, and the outer wall of the slider 904 is slidably connected to the inner wall of the inclined groove 905. Thus, through the cooperation of the inclined groove 905 and the slider 904, the lifting block 903 can be slightly raised during the movement, so that when the horizontal bar 706 moves down, it can be slightly tilted upward. This allows several scissors to move to the side away from the door 5 under the action of gravity, thereby re-guiding and confirming the position and posture of several scissors, so that they are close to each other and vertically downward, realizing the accurate fixation of the subsequent protrusion 720. This makes it easy for several protrusions 720 to be accurately inserted into the gaps between several scissors when they are raised, avoiding unexpected situations that may lead to separation failure.

[0049] Furthermore, when loading new scissors, the blades may not be vertically downwards during manual installation by medical personnel, resulting in an angular deviation. After the scissors with this deviation are placed, the already placed scissors will compress and shape the newly placed scissors, making it impossible to correct the angular deviation. This can easily lead to mechanical jamming or damage to the scissors during subsequent dynamic opening and closing of all scissors due to the non-parallelism of the pivots and the angular deviation. Therefore, after loading, when the crossbar 706 is moved downwards, it can be slightly tilted upwards, allowing several scissors to move to the side away from the box door 5 under the action of gravity, thereby enabling the position and posture of several scissors to be re-guided and confirmed.

[0050] The working principle of this invention is as follows: First, the box door 5 is opened, and then the end rings of several scissors are inserted into the outer surface of the two placement crossbars 706 in sequence. After the scissors are loaded, the loaded scissors are blocked by screwing the blocking handle 708 into the threaded post 707 to prevent them from falling off. Then, the box door 5 is closed, and the disinfectant is sent into the disinfection box 1 through the liquid supply device 2 to soak and disinfect the loaded scissors. After the disinfection and sterilization are completed and the disinfectant is discharged, they can be dried through the drying device 3 on the top.

[0051] Then, when the box door 5 is almost completely closed, the sliding column 715 will slide from the long lower surface to the short higher surface, so that the sliding column 715 will drive the sliding plate 712 to slide on the surface of the connecting rod 711. At this time, through the cooperation of the ball 714 and the rotating groove 713, the connecting rod 711 will drive the rotating rod 709 to rotate synchronously through the universal joint 710. When the rotating rod 709 rotates ninety degrees, it can simultaneously squeeze the several mounting blocks 718 symmetrically arranged in the horizontal bar 706 through the protrusion 716, so that they retract into the mounting groove 717 and squeeze the spring 719. Thus, through the cooperation of the protrusion 720 and the through hole 721, several protrusions 720 can simultaneously extend out of the through hole 721 and automatically embed into the adjacent scissor gap, thereby automatically separating and fixing several scissors on the horizontal bar 706.

[0052] When the door 5 is fully closed, several protrusions 720 separate and fix several scissors. At this time, the sliding column 715 slides into the junction of the short, high surface and the high, curved surface, and the bottom of the connecting frame 806 contacts the lifting plate 808. The drive motor 801 then rotates the cam 802, causing the lifting plate 808 to press and lift the connecting frame 806. With the cooperation of the limiting groove 805, as the connecting frame 806 rises, the sliding column 715 and the high... The curved surfaces allow the two horizontal bars 706 to separate in an arc shape, and the tension spring 807 then drives the two sliding columns 715 back to the junction of the short high surface and the high arc surface. This achieves the separation and merging of the blades during several scissor immersion disinfection processes. It can both open the blades to ensure comprehensive sterilization and use the shearing friction generated by the closing of the scissor blades to peel off the biofilm adhering to the blade surface, avoiding stubborn dirt on the blade surface, thus helping to ensure the disinfection effect of this disinfection device.

[0053] Next, with the door 5 open, the sliding column 715 should be in the long lower position. This allows the support block 901 and the push rod 902 to support and restrict the sliding plate 712 and the connecting rod 711. The lifting block 903 controls the current angle of the two horizontal bars 706, making them slightly tilted downwards at the end near the door 5. This allows the instruments to slide towards the door 5 under the influence of gravity, enabling medical staff to grasp them with "zero contact," reducing the probability of hand contamination and meeting the high-efficiency requirements of the daily processing volume of surgical instruments.

[0054] Then, while the door 5 is closing, the slide plate 712 moves towards the door 5, simultaneously driving the push rod 902 to push the lifting block 903. Through the cooperation of the tilting groove 905 and the slider 904, the lifting block 903 rises slightly during the movement, allowing the horizontal bar 706 to tilt slightly upwards when it moves downwards. This allows several scissors to move away from the door 5 under gravity, thus re-guiding and confirming the position and orientation of the scissors, ensuring they are close together and vertically downwards. This ensures accurate fixing of the subsequent protrusion 720, facilitating accurate insertion of the subsequent protrusions 720 into the gaps between the scissors when they rise, preventing unexpected separation failures.

[0055] While the present invention has been disclosed above, it is not limited thereto. Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
