[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to 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 present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] Traditional reusable medical devices, such as surgical scissors, have complex structures and often overlapping blades. Conventional soaking disinfection is insufficient to thoroughly remove residual dirt or pathogens, while manual scrubbing is cumbersome, inefficient, and carries the risk of operator cuts. Existing disinfection devices mostly focus on static soaking or simple rinsing, lacking dynamic cleaning mechanisms for the moving joints and contact surfaces of the devices. This results in incomplete cleaning, potentially affecting subsequent sterilization effectiveness and increasing the risk of cross-infection. In view of this, this application provides a disinfection device for reusable medical devices, the core of which is to achieve thorough cleaning and disinfection of their surfaces, especially complex joints and overlapping areas, by dynamically simulating the working movements of the medical devices themselves.

[0033] Example 1

[0034] A reusable medical device sterilization device, referring to Figures 1 to 5The system includes a sterilization chamber 1, a turntable 14, and a fixing assembly 3. The sterilization chamber 1 serves as the basic container and outer shell of the device. Its main body is a sealed box structure, typically made of corrosion-resistant stainless steel to ensure long-term chemical stability and structural strength. An opening 11 is provided at the top of the sterilization chamber 1 for inserting or removing medical devices to be processed. To maintain a sealed environment during the sterilization process and prevent leakage of disinfectant aerosols or intrusion of external contaminants, a sealing plate 12 is provided on the sterilization chamber 1, perfectly matching the size of the opening 11. The sealing plate 12 has internal space for installing various components. This sealing plate 12 is not simply a cover; it is controlled by a precise linear sliding mechanism, specifically, the sealing plate 12 slides vertically along the side wall or a dedicated guide rail of the sterilization chamber 1. The disinfection chamber 1 is equipped with a third drive unit 13 for driving the sealing plate 12 to slide vertically. This third drive unit 13 can typically be an electric push rod, a cylinder, or a linear drive mechanism such as a lead screw 49 and nut 48 driven by a motor. Its fixed end is connected to the body of the disinfection chamber 1, while its drive end is rigidly connected to the sealing plate 12, thereby achieving stable and controllable driving of the lifting and lowering movement of the sealing plate 12. The body of the disinfection chamber 1 also has two functional interfaces communicating with the internal cavity, namely, a liquid inlet 15 and a liquid outlet 16.

[0035] The inlet 15 is located on the side of the chamber and is used to connect to an external liquid supply system to pump cleaning or disinfecting solution into the chamber. The outlet 16 is also located at the bottom of the chamber and is used to discharge waste liquid after the cleaning or disinfection process, or as a return port during liquid circulation filtration. Furthermore, to further improve processing efficiency and achieve continuous cleaning, disinfection, and drying operations, a drying assembly 5 is integrated into the disinfection chamber 1. This drying assembly 5 may include a built-in hot air circulation system. In this application, an electric heating element and a matching fan are arranged on the top wall of the disinfection chamber 1, or it can be connected to a hot air or sterile air source through an external interface, thereby rapidly drying the instruments after the liquid processing steps are completed, reducing the risk of secondary contamination.

[0036] Reference Figure 2At least two turntables 14 are provided, arranged parallel to each other at a specific interval, and each is rotatably mounted on the side wall of the disinfection chamber 1 via a bearing seat or rotating shaft structure. The rotation axes of the two turntables 14 are on the same straight line, and this axis is usually parallel to the bottom surface of the disinfection chamber 1. The disinfection chamber 1 is provided with a first drive unit 2 for driving the two turntables 14 to rotate synchronously and in opposite directions. One specific configuration of the first drive unit 2 includes a first drive member 21, a first driving gear 22, and at least two first driven gears 23. The first drive member 21 is usually a servo motor or stepper motor with a reducer, and its output shaft is fixedly connected to the rotating shaft of the first driving gear 22 via a coupling to transmit power to the first driving gear 22. The number of first driven gears 23 is the same as the number of turntables 14, and each first driven gear 23 is fixedly connected to one turntable 14 on the same axis, that is, the rotation center of the first driven gear 23 coincides with the rotation center of the corresponding turntable 14, and the two are connected by a key or flange to achieve synchronous rotation. The first driving gear 22 simultaneously meshes with all the first driven gears 23, forming a shared gear transmission system. With this structure, a single first driving element 21 can drive all the first driven gears 23 and the fixed turntable 14 to rotate synchronously. Crucially, by controlling the direction and speed of the first driving element 21, the rotation direction and angle of the two turntables 14 can be precisely controlled, achieving synchronous rotation in the same direction or synchronous rotation in opposite directions.

[0037] Reference Figure 2 and Figure 3 The fixing component 3 is the part that directly clamps and fixes the medical device, and it is disposed on each turntable 14. Each fixing component 3 includes a mounting rod 31 and at least two sets of fixing claws 32. The mounting rod 31 is fixedly disposed in a direction perpendicular to the surface of the turntable 14 on which it is mounted, that is, the axis of the mounting rod 31 is perpendicular to the surface of the turntable 14. However, the mounting position of the mounting rod 31 is not located at the rotation center of the turntable 14, but is offset from the rotation axis of the turntable 14, with a fixed eccentricity. This means that when the turntable 14 rotates about its own axis, the mounting rod 31 and all its components will move in a circle around the axis of the turntable 14. At least two sets of fixing claws 32 are arranged circumferentially on the mounting rod 31, preferably at uniform intervals. The fixing claws 32 are not directly fixed to the mounting rod 31, but are rotatably connected to the mounting rod 31 through a hinge shaft, and the axial direction of the hinge shaft is perpendicular to the axial direction of the mounting rod 31. In other words, the fixed claw 32 can swing about a horizontal axis (assuming the mounting rod 31 is vertical).

[0038] The fixing claw 32 has a specific shape, with an installation area on its outer wall and a clamping area on its inner wall. The functional design of the installation and clamping areas enables two distinctly effective and stable fixing modes for different types of medical devices. When handling instruments such as surgical scissors with closed or semi-closed finger rings at the end of the handle, the installation claw 322 at the front end of the fixing claw 32, with its relatively slender profile, can directly penetrate into the finger ring of the scissor handle. Subsequently, the second drive unit 4 precisely drives the parallel four-bar linkage mechanism, causing the two sets of fixing claws 32 to perform synchronous rotations in opposite directions, i.e., the fixing claw 32 swings outward around its hinge axis with the installation rod 31. This expansion movement forces the specifically constructed installation area on the outer wall of the installation claw 322 to tightly press against and lock onto the inner wall of the finger ring of the scissor handle, thereby achieving a reverse locking from the inside out using the instrument's own structure, ensuring a secure fixation and preventing accidental dislodgement. Correspondingly, the clamping area is mainly used for instruments with handles lacking finger rings or structures unsuitable for expansion and fixation from the inside out, such as the smooth handles of certain forceps and needle holders. In this mode, the second drive unit 4 drives the parallel four-bar linkage mechanism, driving the two sets of fixing claws 32 to perform synchronous, inward rotation towards each other. This causes the clamping area on the inner wall of the fixing claws 32 to converge from both sides towards the center, thereby generating a uniform, inward clamping force on the instrument handle and achieving a firm grip. These two fixation modes share the same drive mechanism and can be flexibly switched simply by controlling the drive direction and replacing the mounting claw 322 components, greatly expanding the device's adaptability and handling capabilities for medical devices with different structures.

[0039] Example 2

[0040] Reference Figure 4 and Figure 5The second drive unit 4 is a precision transmission mechanism that controls the clamping and releasing actions of the fixing claw 32, and it is located inside the sealing plate 12. One specific embodiment includes a drive rod 41, a first connecting rod 42, a second connecting rod 43, a drive connecting rod 44, and a second drive source 45. First, the mounting rod 31 is designed as a hollow tubular structure, forming an internal channel through which other parts can pass. The drive rod 41 slides through the hollow mounting rod 31, and its axial sliding is constrained by the inner wall of the mounting rod 31, allowing it to only reciprocate linearly along the axis of the mounting rod 31. The first connecting rod 42 and the second connecting rod 43 are two sets of equal and parallel connecting rods, forming the kinematic connection between the fixing claw 32 and the mounting rod 31. One end of the first connecting rod 42 is hinged to the outer wall of the mounting rod 31 via a first hinge point, and the other end is hinged to the main body of a fixing claw 32 via a second hinge point. Similarly, one end of the second link 43 is hinged to the outer wall of the mounting rod 31 via the third hinge point, and the other end is hinged to the main body of the same fixed claw 32 via the fourth hinge point. The first and third hinge points are axially spaced at a certain distance on the mounting rod 31, and the second and fourth hinge points are also axially spaced at a corresponding distance on the fixed claw 32, thus forming a parallel four-bar linkage together with the first link 42 and the second link 43. The drive link 44 is used to convert the linear motion of the drive rod 41 into the oscillation of the second link 43, thereby driving the entire parallel four-bar linkage to move, so that the multiple fixed claws 32 can always be in a parallel state. One end of the drive link 44 is hinged to the end of the drive rod 41 via the fifth hinge point, and the other end is hinged to the middle of the second link 43 or the end near the mounting rod 31 via the sixth hinge point. Of particular importance is that the hinge axes of all the aforementioned hinge points must be parallel to each other and parallel to the main hinge axis between the fixed claw 32 and the mounting rod 31. Typically, they are perpendicular to the axis of the mounting rod 31 to ensure the accuracy and consistency of motion transmission. A second drive source 45 is fixedly mounted on the turntable 14 to provide power to drive the drive rod 41 to slide along the axis of the mounting rod 31. The second drive source 45 can be a linear motor, a cylinder, or more commonly, a rotary motor combined with a motion conversion mechanism.

[0041] A detailed configuration of the second drive source 45 integrated with the turntable 14 is as follows: The second drive source 45 is specifically located in the back or side space of the first driven tooth 23 corresponding to the turntable 14. It includes a second drive element, a second driving tooth 46, a second driven tooth 47, a nut 48, and a lead screw 49. After passing through the mounting rod 31, the drive rod 41 continues to extend and passes through the central through hole of the first driven tooth 23 of the turntable 14. A lead screw 49 is coaxially fixed on the extension of the drive rod 41, that is, the axis of the lead screw 49 is consistent with the sliding direction of the drive rod 41. A nut 48 is rotatably supported on a specific bracket of the first driven tooth 23 by a bearing, and the internal thread of the nut 48 forms a threaded transmission connection with the external thread of the lead screw 49. The second driven tooth 47 is coaxially fixedly fitted on the outer circumference of the nut 48 and rotates with it. The second drive element (such as a small motor) is fixedly mounted on the support structure of the first driven tooth 23 or the turntable 14, and its output shaft is connected to the second driving tooth 46. The second driving tooth 46 is meshed with the second driven tooth 47 for transmission. When the second driving component is working, it drives the second driving tooth 46 to rotate, which in turn drives the second driven tooth 47 and the nut 48 to rotate together. The rotational motion of the nut 48 is converted into the linear motion of the lead screw 49 through the threaded pair. Since the lead screw 49 is fixed to the driving rod 41, the driving rod 41 is pushed and pulled, realizing its sliding along the axis of the mounting rod 31.

[0042] Example 3

[0043] Reference Figure 2 and Figure 3 The specific structure of the fixing claw 32 can be further optimized. The fixing claw 32 consists of two parts: a main body 321 and a mounting claw 322. The main body 321 is the base part that is directly hinged to the mounting rod 31 and the linkage mechanism, forming the motion skeleton of the fixing claw 32. The mounting claw 322 is the functional component that actually supports the mounting area and the clamping area. It is set on the main body 321 through a detachable connection method (such as screw fixing, snap connection, dovetail groove sliding fit and locking, etc., not shown in the figure). This split design allows the mounting claw 322 to be quickly replaced according to the clamping requirements of different medical devices, improving the versatility of the device. The mounting claws 322 on the multiple fixing claws 32 remain parallel to each other in the working state to ensure parallel clamping of the two symmetrical parts of the device. The mounting area is set on the mounting claw 322, specifically manifested as multiple specific structures spaced apart along the length of the mounting claw 322, such as a series of holes, slots or standard clamp interfaces. These mounting areas can be used to mount different adapter heads or directly fix instrument handles of different sizes. By selecting different mounting area positions, the clamping points can be fine-tuned to accommodate size variations of surgical instruments ranging from small to medium. The clamping area is located on the inner wall of the mounting claw 322, facing the instrument being clamped, and is usually covered with flexible or non-slip material to increase friction and prevent damage to the instrument surface.

[0044] The specific workflow of this device fully demonstrates the synergistic effect of its mechanical structure. When cleaning and disinfecting instruments such as surgical scissors, which have two movable handles and are hinged by a pivot pin, the operator first raises the sealing plate 12 on top of the disinfection tank 1 via the third drive unit 13, opening the opening 11. The two scissor handles are respectively placed onto the mounting claws 322 of the corresponding fixing claws 32 on the two turntables 14. At this time, the parallel four-bar linkage is precisely driven by the second drive unit 4, causing the two sets of fixing claws 32 to perform synchronous rotations in opposite directions, that is, the fixing claws 32 swing outward around their hinge axis with the mounting rod 31. This expansion movement forces the mounting area with a specific structure on the outer wall of the mounting claw 322 to press tightly against and lock onto the inner wall of the scissor handle finger ring, thereby achieving reverse locking from the inside out using the instrument's own structure, ensuring a secure fixation and preventing accidental dislodgement. Then, the sealing plate 12 is closed, and disinfectant is injected into the disinfection tank 1 through the inlet 15 until the instruments are submerged. Next, the first drive unit 2 operates: the first drive component 21 is activated, driving the two turntables 14 to begin synchronous but opposite rotational motions through gear transmission via the first active gear 22 and two first driven gears 23. Because the mounting rod 31 is misaligned with the rotation axis of the turntable 14, when the two turntables 14 rotate in opposite directions, the two mounting rods 31 respectively drive the scissor handles held by their fixing claws 32, performing a relative opening and closing motion, perfectly simulating the opening and closing action of surgical scissors in actual use. During this dynamic process, disinfectant is forcibly pumped into and out of areas that are difficult to thoroughly clean through static soaking, such as the overlapping parts of the scissor blades and the gaps between hinge joints, achieving a full combination of physical rinsing and chemical disinfection. After the cleaning and disinfection process is completed, the waste liquid is discharged from the outlet 16, and then the drying component 5 is activated, sending clean hot air into the chamber to dry the instruments. Finally, the sealing plate 12 is opened to remove the instruments. The entire process is highly automated, requiring no direct manual contact with the sharp instruments during cleaning, making it safe and efficient, and the cleaning effect is significantly better than static soaking.

[0045] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
