[0002] Medical instrument refers to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators and other related articles directly or indirectly used for human body. Among numerous medical instruments, surgical instruments with opening and closing structure are commonly used medical instruments in surgical process, such as surgical scissors and surgical forceps. Such medical instruments (hereinafter collectively referred to as surgical instruments) are cross-type structure design, one end of which is a ring for holding, and the other end is a blade or a forceps head for surgical operation.

[0003] In the prior art, the disinfection of surgical instruments is generally by immersion or spraying. During the disinfection process, the blades or forceps heads on both sides of the surgical instruments cannot always be kept apart, so they cannot be kept exposed. Therefore, it is not conducive to disinfecting the blades or forceps heads when they are closed, and bacteria and viruses may still remain in the combined blades or forceps heads. The incomplete disinfection of surgical instruments may cause infection to patients and pose a great risk to surgery when they are used again. SUMMARY

[0019] In an implementation of the first aspect, the sterilization pool is fixed to a base, and the sterilization pool is a ring-shaped water tank, and the base is provided with a bearing seat located at the center of the sterilization pool, and the lower end of the mounting shaft is inserted into and fixed to the bearing seat.

[0020] In a second aspect, the application provides a working method of the sterilization device, and the method comprises the following steps:

[0021] The guide ring is rotated to drive the rotating cylinder to rotate, and the rotating cylinder is paused after the rotating plate of the clamping device faces the operation window.

Then the guide ring is reset to overturn 180° upward, so that the surgical instrument is overturned upward to be located below the heating unit and corresponds to the operation window, so that the heating unit disinfects and dries the surgical instrument at high temperature. Therefore, the present application can also realize intelligent automatic disinfection and drying of the surgical instrument, and this process is completely manual, which is very convenient.

[0044] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0045] Hereinafter, the terms “first”, “second”, and the like are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with “first”, “second”, and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of “a plurality of” is two or more.

[0046] In addition, in the present application, the orientation terms such as “up”, “down”, and the like are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0047] The present application provides an automatic medical disinfection device and a working method thereof, as shown in the accompanying drawings Figure 1and 2 As shown, the disinfection device includes a housing 1, a flipping device, a clamping device 3, and a disinfection device. A centrally fixed mounting shaft 11 is located within the housing 1, and multiple operating windows 101 are distributed on the side of the housing 1. The flipping device, clamping device 3, and disinfection device are all housed within the housing 1. The clamping device 3 is used to clamp and fix surgical instruments 5, and the flipping device is located around the mounting shaft 11 to rotate the surgical instruments 5 clamped and fixed by the clamping device 3, thereby causing the surgical instruments 5 to swing from the operating windows 101 into the disinfection device for automatic disinfection.

[0048] The flipping device includes an attached Figures 4 to 6 The attached diagram shows a mounting bracket 21, a guide ring 22, a rotating cylinder 23, and a sensing device. The mounting bracket 21 has a petal-shaped structure with multiple supporting rods distributed around its periphery. The center of the mounting bracket 21 is fitted onto the mounting shaft 11, and the mounting bracket 21 is directly fixed to the mounting shaft 11 near its center by welding. The bottom surface of the guide ring 22 has multiple protruding guide pins 221 distributed in a ring. The guide ring 22 is also connected to the mounting bracket 21 via a suspension member 25 and a ring rail 26, allowing it to rotate. Further details can be found in the attached diagram. Figure 15 and 16 An annular rail 26 is fixed above the guide ring 22, and both the inner and outer annular surfaces of the annular rail 26 are recessed inward to form a first guide groove 261. Multiple suspension members 25 are annularly distributed and fixed on the bottom surface of the fixing frame 21 near its outer edge. The suspension members 25 can be fixed under the support rod of the fixing frame 21. Each suspension member 25 includes a connecting frame 251 and a guide wheel 252. The two ends of the connecting frame 251 are mirror-shaped C-shaped curved structures, forming an opening at the bottom of the connecting frame 251. Both ends of the connecting frame 251 are connected to the guide wheel 252. Specifically, both sides of the guide wheel 252 are fitted with fixed bearings. Bolts are screwed into both ends of the connecting frame 251 from bottom to top. These bolts are screwed in spirally and tightened within the connecting frame 251 while passing through the bearings on both sides of the guide wheel 252, thus restricting the rotation of the guide wheel 252 within the connecting frame 251. The guide wheels 252 on both sides of each connecting frame 251 are respectively embedded in the first guide grooves 261 on the inner and outer ring surfaces of the annular rail 26, thereby suspending the annular rail 26 and restricting the annular rail 26 to rotate only under the fixed frame 21 with the mounting shaft 11 as the axis.

[0049] Furthermore, a gear ring 27 is fixed between the guide ring 22 and the annular rail 26. The fixing frame 21 is connected to the drive gear 28, which meshes with the gear ring 27. A drive motor 281 is also fixed on the fixing frame 21. The drive motor 281 drives the drive gear 28 to rotate, thereby driving the gear ring 27 and the guide ring 22 to rotate, which in turn drives the guide pins 221 distributed on the bottom surface of the guide ring 22 to rotate around the mounting shaft 11.

[0050] As attached Figure 6 and 8As shown, the inner wall of the rotating cylinder 23 is concave to form a spiral groove 231, the two ends of the spiral groove 231 pass through the two ends of the rotating cylinder 23, and the inner wall of the rotating cylinder 23 is annularly distributed with a plurality of spiral grooves 231. The guide ring 22 is sleeved with the rotating cylinder 23 outside the position corresponding to each operation window 101, and the rotating cylinder 23 is limited to only rotate relative to the fixed frame 21. Specifically, the rotating cylinder 23 is connected by two cylinder segments along its diameter, and the cross section of the cylinder segment is a semicircular ring. Specifically, the cylinder segment is attached to the fixed frame 21 by a bolt. Figure 8 As shown, the structure of the upper part of the connecting plate 233. After the two cylinder segments are respectively close to the middle from both sides of the guide ring 22 and fit, the rotating cylinder 23 is formed by being sleeved outside the guide ring 22 through the bolt.

[0051] Further, continuing to refer to the drawings Figure 4 and 6 The annular surface of the rotating cylinder 23 is provided with a reduced diameter portion 232 near the position of the two ends, and the fixed frame 21 is fixed with a limiting frame 29 at the two ends of the rotating cylinder 23. The limiting frame 29 is provided with a limiting hole (not shown in the figure), and the two reduced diameter portions 232 are respectively gap-fitted in the two limiting holes, so as to limit the rotating cylinder 23 to only rotate around its axis relative to the limiting frame 29 and the fixed frame 21. Preferably, the part of the limiting frame 29 in the limiting hole can also be divided into two parts with two concave arc shapes, one of which is fixed on the fixed frame 21 and sleeved behind the reduced diameter portion 232 of the rotating cylinder 23, and the other is sleeved on the reduced diameter portion 232 from bottom to top. The two parts can be fixed by bolts to form a structure in which the limiting frame 29 limits the reduced diameter portion 232 of the rotating cylinder 23 through the limiting hole.

[0052] After adopting the above structure, when the guide pin 221 rotates to the position of the rotating cylinder 23 in the process of rotating the guide ring 22 to drive the guide pin 221 to move, the guide pin 221 penetrates each spiral groove 231 one by one, thereby driving the rotating cylinder 23 to rotate, that is, realizing the synchronous and same direction rotation of the rotating cylinder 23 driven by the rotation of the guide ring 22. It is worth mentioning that the distance between the two adjacent guide pins 221 is consistent with the distance between the opening positions of the adjacent spiral grooves, so that after one of the guide pins 221 penetrates the spiral groove and drives the rotating cylinder 23 to rotate, the guide pin 221 behind it moves to the rotating cylinder 23, and the spiral groove 231 behind it also rotates to correspond to the guide pin 221 behind it, so that the guide pin 221 behind it also penetrates into the spiral groove 231 behind it, and the cycle is repeated to form the action mode in which the rotating cylinder 23 is always driven to rotate by the rotation of the guide ring 22.

[0053] Each rotating cylinder 23 is connected with the clamping device 3, as shown in the drawings Figure 6 and 7As shown, the clamping device 3 comprises a rotating plate 31, a placing piece 32 and a pressing piece 33. The rotating plate 31 is fixed to the rotating cylinder 23, and both ends of the rotating plate 31 are fixed with the placing piece 32. The placing piece 32 can be L-shaped, one side of which is fixed to the rotating plate 31, and the other side is used to hang one of the finger rings 51 of the end of the surgical instrument 5. The pressing piece 33 is limited to rotate relative to the placing piece 32, and can be, for example, as shown in the attached Figure 12 As shown, the middle part of the pressing piece 33 and the placing piece 32 are hinged by a pin shaft, and a torsion spring 34 is arranged between the pressing piece 33 and the placing piece 32. The torsion spring 34 can be sleeved outside the pin shaft, and both ends of the torsion spring 34 are respectively abutted against the placing piece 32 and the end of the pressing piece 33 close to the rotating plate 31, so that the torsion of the torsion spring 34 pushes the end of the pressing piece 33 away from the rotating plate 31 to the finger ring 51 of the surgical knife hung on the placing piece 32, thereby fixing the surgical instrument 5, and further keeping the two side blade parts or the clamping heads of the surgical instrument 5 in a fixed open state to be completely exposed. Preferably, the end of the placing piece 32 and the end of the pressing piece 33 can be provided with guide inclined surfaces, and when the surgical instrument 5 is clamped, the two finger rings 51 of the surgical instrument 5 are respectively pushed along the guide inclined surfaces of the placing piece 32 and the pressing piece 33 to push up the pressing piece 33, so that the finger ring 51 of the surgical instrument 5 is clamped between the placing piece 32 and the pressing piece 33 to be fixed. This clamping method is more convenient.

[0054] As shown in the attached Figure 8 One of the cylinder sections of the rotating cylinder 23 can be fixed with a connecting plate 233, and the connecting plate 233 is screw-connected with an adjusting bolt 35, and the adjusting bolt 35 is screw-connected with the connecting plate 233 after passing through the fixed hole in the center of the rotating plate 31, so that the rotating plate 31 is fixed relative to the rotating cylinder 23. When it is necessary to adjust the parallel or vertical state of the rotating plate 31 relative to the rotating cylinder 23, the adjusting bolt 35 is loosened and then the rotating plate 31 is rotated to achieve the adjustment. This way, the clamping device 3 can fix various surgical instruments 5, and after the rotating cylinder 23 is rotated downward, the whole surgical instrument 5 can be immersed in the disinfection pool 41. Specifically, it can be applied to fix, for example, the attached Figure 6 In addition, it can also be applied to fix, for example, the attached Figure 13 The separating forceps.

[0055] As shown in the attached Figure 6 and 11As shown, the second guide slot 311 of T-shaped structure is also arranged in the rotating plate 31, which penetrates the center of the rotating plate 31 and is used for passing the fixing hole of the adjusting bolt 35. The second guide slot 311 is also fitted with the slider 36 of T-shaped structure on both sides of the fixing hole. The two placing pieces 32 are respectively fixed to the two sliders 36 on one side of the rotating plate 31, so that the distance between the two placing pieces 32 can be adjusted, thereby the surgical instruments 5 of different sizes can be kept in an open state, which is convenient for sterilization and drying. Further, the two ends of the rotating plate 31 are rotated inwardly into the positioning bolt 37, and the studs of the two positioning bolts 37 are respectively pushed towards the two sliders 36. The rotating plate 31 is also fixed with two stop blocks in the second guide slot 311, which can be fixed by the way of passing the screw. The spring is arranged between the two stop blocks and the two sliders 36 respectively, and the elastic force of the spring can push the slider 36 towards the positioning bolt 37. When operating, the positioning bolt 37 is moved towards the fixing hole by rotating the positioning bolt 37, so that the placing piece 32 is pushed towards the center of the rotating plate 31, thereby reducing the distance between the two placing pieces 32. The positioning bolt 37 is moved outwardly from the rotating plate 31 by rotating the positioning bolt 37 outwardly, so that the placing piece 32 is pushed outwardly from the rotating plate 31 under the action of the spring, thereby expanding the distance between the two placing pieces 32. It can be seen that the structure of the second guide slot 311, the slider 36, the positioning bolt 37 and the spring connecting the placing piece 32 can change the distance between the two placing pieces 32 as required, so that the surgical instruments 5 of different sizes can be kept in a fixed open angle after being clamped by the two placing pieces 32.

[0056] As shown in the accompanying drawings, Figure 2 and 3 As shown, the center of the top surface of the shell 1 is provided with a penetrating mounting hole, and the top surface of the mounting shaft 11 is screw-connected with the fixing bolt 12. When fixing the mounting shaft 11, the stud of the fixing bolt 12 is penetrated through the mounting hole and is screw-connected with the mounting shaft 11 to be fastened, so that the mounting shaft 11 is fixed in the shell 1, and the turnover device and the clamping device 3 are suspended in the shell 1. Further, the top surface in the shell 1 is also fixed with the shaft sleeve 17, the shaft sleeve 17 is provided with a positioning hole of regular hexagonal section, the positioning hole penetrates the bottom surface of the shaft sleeve, the top surface of the mounting shaft 11 is provided with the hexagonal prism 113 matched with the positioning hole, the fixing bolt 12 is screwed from the top surface of the hexagonal prism 113, the hexagonal prism of the mounting shaft 11 is sleeved in the positioning hole of the shaft sleeve 17, and then the stud of the fixing bolt 12 is penetrated through the mounting hole and is screw-connected with the mounting shaft 11 to be fastened. The positioning hole of the shaft sleeve 17 is used for positioning the hexagonal prism 113 of the mounting shaft 11, so that the mounting shaft 11 is fixed, and each clamping device 3 is kept corresponding to the operation window 101 of the shell 1.

[0057] As shown in the accompanying drawings, Figure 2 and 14As shown, the disinfecting device comprises a disinfecting tank 41, a heating unit 42 and a lamp holder 43. The lamp holder 43 is fixed to the mounting shaft 11, and the lamp holder 43 is also fixed with the heating unit 42 at the position between each rotating cylinder 23 and the mounting shaft 11, which is equivalent to connecting the heating unit 42 to the side of the mounting shaft 11 and above the fixed frame 21. The heating unit 42 in this embodiment can be an electric heating tube or other electrical element that converts electric energy into heat energy. The fixing structure of the lamp holder 43 can be as shown in the attached Figure 4 and 15 As shown, the upper end of the mounting shaft 11 is provided with a section of external thread 111 with reduced outer diameter, so that the mounting shaft 11 forms a shaft shoulder 112 at the lower end of the external thread 111. The external thread 111 is also screw-connected with a fixing nut 13. When fixing the lamp holder 43, the center of the lamp holder 43 is sleeved outside the external thread 111, and then the fixing nut 13 is screwed downward to fasten, so that the fixing nut 13 presses and fixes the lamp holder 43 on the shaft shoulder 112 of the mounting shaft 11, thereby arranging the heating unit 42 between each rotating cylinder 23 and the mounting shaft 11, i.e. arranging the heating unit 42 in each clamping device 3, so that the heating unit 42 can perform high-temperature disinfection and drying on the surgical instrument 5 clamped by the clamping device 3.

[0058] Continuing to refer to the attached Figure 2 The disinfecting tank 41 is arranged below the housing 1, and an ultrasonic generator is arranged in the disinfecting tank 41, so that the disinfecting liquid in the disinfecting tank 41 forms ultrasonic vibration. When the rotating cylinder 23 rotates to immerse the surgical instrument 5 in the disinfecting tank 41, the disinfecting liquid in the disinfecting tank 41 is used to disinfect the surgical instrument 5, and at the same time, the cavitation effect, acceleration effect and direct flow effect of the ultrasonic wave in the disinfecting liquid are used to directly and indirectly act on the liquid and dirt, so that the dirt layer on the surface of the surgical instrument 5 is dispersed, emulsified and peeled off, thereby achieving the purpose of cleaning and disinfecting the surgical instrument 5.

[0059] As shown in the attached Figure 9 and 10As shown, the sensing device is arranged below the fixing frame 21, and the sensing device comprises an infrared emitter 241 and two infrared receivers 242, specifically a first receiver and a second receiver. The infrared emitter 241 is fixed below the fixing frame 21, and the first receiver and the second receiver are both fixed on the upper surface of the driving gear 28 at different positions. The first receiver and the second receiver are both in signal connection with a control system, so that the control system controls the driving motor 281 to start and stop according to the received signals, thereby controlling the driving gear 28 to rotate to a specified angle and then pause, and further realizing that the rotating cylinder 23 rotates to a specified angle and then pauses through the sensing of the sensing device 24. The specified angle of the rotation of the rotating cylinder 23 is the angle at which the surgical instrument 5 held by the clamping device 3 driven by the rotating cylinder 23 reciprocates upward and downward to face the operation window 101 and immerse into the sterilization pool 41. Preferably, the connection line between the first receiver and the center of the driving gear 28 and the connection line between the second receiver and the center of the driving gear 28 form a specified angle, which is the specified angle of the rotation of the rotating cylinder 23 or an integer multiple of the specified angle. In addition, the control system is also used to control the working state of the ultrasonic generator and the heating unit 42.

[0060] Specifically, in the process of the rotation of the driving gear 28 and the driving of the guide ring 22, when the driving gear 28 rotates to the first receiver to sense the infrared signal emitted by the infrared emitter 241, the first receiver transmits the signal to the control system, and the control system controls the driving motor 281 to pause according to the signal. At this time, the rotating cylinder 23 rotates to the vertical upward of the clamping device 3 to face the operation window 101. When the driving gear 28 rotates to the second receiver to sense the infrared signal emitted by the infrared emitter 241, the second receiver transmits the signal to the control system, and the control system controls the driving motor 281 to pause according to the signal. At this time, the rotating cylinder 23 rotates to the vertical downward of the clamping device 3 to immerse the surgical instrument 5 into the sterilization pool 41. Based on the above sensing of the rotation angle of the driving gear 28 by the sensing device, the intelligent positioning of the driving gear 28 during rotation is realized by the information exchange and communication of the driving gear 28 through the information transmission medium, so that the present application can form the following working mode:

[0061] The driving motor 281 drives the driving gear 28 to rotate to drive the guide ring 22 to rotate. When the driving gear 28 rotates to the first receiver to receive the signal of the infrared emitter 241, the control system controls the driving motor 281 to pause according to the signal, so that the rotating cylinder 23 rotates to the rotation plate 31 of the clamping device 3 to face the operation window 101 and then pauses.

[0062] The medical staff places the surgical instrument 5 into the shell 1 from the operation window 101, so that the two finger rings 51 of the surgical instrument 5 are clamped and fixed by the placing pieces 32 and the pressing pieces 33 at both ends of the rotation plate 31.

[0063] The driving motor 281 drives the driving gear 28 to rotate reversely to drive the guide ring 22 to rotate reversely, when the driving gear 28 receives the signal from the infrared emitter 241, the control system controls the ultrasonic generator to start and controls the driving motor 281 to pause according to the signal, at this time, the driving gear 28 drives the guide ring 22 to rotate reversely by 180°, so that the surgical instrument 5 is turned down to immerse in the disinfectant in the disinfection pool 41 to be disinfected by ultrasonic wave;

[0064] When the preset time arrives, the control system controls the heating unit 42 to start, and at the same time, the control system controls the driving motor 281 to work to drive the driving gear 28 to rotate, so that the guide ring 22 is reset to rotate by 180° upwards, so that the surgical instrument 5 is turned up to be located below the heating unit 42 and faces the operation window 101, so that the heating unit 42 disinfects and dries the surgical instrument 5 at high temperature;

[0065] When the preset time arrives, the control system controls the heating unit 42 to close, and then the disinfected surgical instrument 5 is taken out from the operation window 101.

[0066] The preset time in the above working method can be the time input to the control system in advance, that is, the time of ultrasonic decontamination and high-temperature disinfection, so as to form intelligent control. And through the above method, it can be seen that the surgical instrument 5 only needs to be clamped from the operation window 101, and then the surgical instrument 5 is taken out from the operation window 101 after disinfection is completed, which is very convenient.

[0067] In addition, as shown in the accompanying drawings, Figure 2 The disinfection pool 41 is fixed to the base 18, and the disinfection pool 41 is a ring-shaped water tank, so that the disinfection pool 41 leaves a space in the center of the base 18, and the bearing seat is fixed on the space, that is, the bearing seat is located in the center of the disinfection pool 41, and the lower end of the shaft 11 penetrates and is fixed to the bearing seat, so that the shell 1 can rotate relative to the base. When the surgical instrument 5 is clamped, after the medical staff clamps the surgical instrument 5 into the shell 1 at one operation window 101, the shell 1 can be directly rotated to the next operation window 101 facing the medical staff to clamp the surgical instrument 5 again, without rotating the shell 1 to clamp the surgical instrument 5 from each operation window 101 one by one, which can improve the convenience of operation.

[0068] Continuing to refer to the accompanying drawings, Figure 1The shell 1 is further provided with a protective cover 14 which is adapted to be sleeved outside the shell 1, and the position of the shell 1 below the operation window 101 is further fixed with a supporting table 15 to block the protective cover 14, so that after the protective cover 14 is sleeved outside the shell 1, the supporting table 15 can support the protective cover 14, and the protective cover 14 can shield each operation window 101, so that a relatively closed space is formed inside the shell 1, and the high-temperature air is prevented from leaking out during the process of heating and disinfecting the surgical instrument 5 by the heating unit 42, so as to affect the efficiency of high-temperature disinfection and drying of the surgical instrument 5. Figure 17 The shell 1 is provided with a vertical moving groove 102 and a horizontal limiting groove 103 which is connected to the upper end of the moving groove 102, and a limiting bolt 16 is screwed into the protective cover 14, and the limiting bolt 16 can be adapted to be penetrated into the moving groove 102 and the limiting groove 103. When the surgical instrument 5 needs to be clamped, the protective cover 14 is lifted upward, the limiting bolt 16 is moved upward along the moving groove 102, and then the protective cover 14 is rotated until the limiting bolt 16 is moved into the limiting groove 103, so that the limiting bolt 16 is blocked by the limiting groove 103, and the protective cover 14 lifted upward cannot drop downward, so that each operation window 101 is kept in an open state.

[0069] As described above, the intelligent positioning of the driving gear 28 during rotation is realized based on the sensing of the driving gear 28 by the inductive device 24, so that the 180° reciprocating rotation of the rotating cylinder can be realized by driving the guide ring 22 to rotate during the process of driving the driving gear 28 to rotate by the driving motor 281. Therefore, after the surgical instrument 5 is fixed in the clamping device from the operation window 101 into the shell 1, the rotation of the driving gear 28 drives the guide ring 22 to rotate 180°, so that the rotating cylinder 23 drives the surgical instrument 5 to overturn downward to immerse in the disinfectant in the disinfecting pool 41 for ultrasonic decontamination and disinfection, and then the driving gear 28 is rotated again to drive the guide ring 22 to rotate reversely by 180° to reset, so that the surgical instrument 5 is overturned upward to face the heating unit 42, and the heating unit 42 performs high-temperature disinfection and drying on the surgical instrument 5. Therefore, the intelligent automatic disinfection and drying of the surgical instrument 5 can be realized, and the process is operated without manual operation, which is very convenient.

[0070] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application by using the concept should be regarded as an infringement of the protection scope of the present application.
