Abstract
Description
Technical Field
[0001] This invention relates to the field of instrument sterilization station technology, and more particularly to an instrument sterilization station for use in medical orthopedic surgery. Background Technology
[0002] Orthopedics is one of the most important departments in a hospital. Common orthopedic diseases include frozen shoulder, cervical spondylosis, lumbar disc herniation, tendinitis, arthritis, synovitis, joint dislocation, and fractures. When these diseases are severe, they usually require surgery to be cured. Since these orthopedic surgeries are all performed using surgical instruments, the cleaning, disinfection, and sterilization of medical surgical instruments are one of the key measures to ensure the quality of surgery.
[0003] For example, a sterilization table for surgical instruments used in orthopedic surgery, as described in patent number "CN106037944B", includes a fixed frame. A base plate is mounted on the lower end of the fixed frame, and four casters are symmetrically mounted on the lower end of the base plate. Four parallel chains are mounted on the inner walls of the four sliders of the four lifting chains, and an operating platform is mounted on the top of each of the four parallel chains. A fixed column is welded to the upper end of the operating platform, and a fixed disc is welded to the upper end of the fixed column. Six fixed holes are symmetrically arranged on the fixed disc, and six sterilization lifting chains are fixedly installed in each of the six fixed holes. This invention can achieve ultrasonic cleaning, sterilization, and disinfection of surgical instruments, as well as the functions of classifying and quickly retrieving surgical instruments, thus accelerating the surgical process, improving work efficiency, and offering advantages such as simple operation, good sterilization and disinfection effect, and adjustable lifting height.
[0004] However, in existing technologies, the operating tables used for orthopedic instruments have relatively simple functions. They typically have a cleaning pool for cleaning instruments and an operating platform for packaging the cleaned instruments. Most instruments need to be placed in a special box after cleaning, wrapped with multiple layers of sterile medical cloth, and sealed. After being labeled, the box is placed in a high-temperature and high-pressure sterilization device for a period of time. This packaging step is usually performed on the operating platform. Existing orthopedic instrument operating tables usually only have these two main functions, which are relatively simple. After the instruments are packaged, they need to be placed on an additional support, and staff need to transfer them to other sterilization equipment in the sterilization room, which increases the workload of medical staff to some extent. Summary of the Invention
[0005] The purpose of this invention is to solve the problem that the existing instrument sterilization tables have relatively simple functions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an instrument sterilization table for medical orthopedic surgery, comprising a washing table and an operating table, wherein the end face of the washing table is perpendicular to one side of the operating table, a washing pool and a drain rack are respectively provided at both ends above the washing table, the drain rack is located above the end of the washing table near the operating table, a soaking pool is provided at the center of the upper part of the operating table, an adjustable operating board is provided inside the soaking pool, slide rails are provided on both sides above the operating table, a sterilization rack is slidably provided above the operating table, the sterilization rack is slidably mounted on the slide rails, a high-temperature sterilization device is provided at the end of the operating table away from the washing table, the inlet of the high-temperature sterilization device is located above the operating table, and the sterilization rack is slidably placed inside the high-temperature sterilization device.
[0007] In a preferred embodiment, the drain rack is equipped with a blower mechanism on the side near the operating table. The blower mechanism includes a fan, a side frame, air ducts, and nozzles. Multiple air ducts are provided and are respectively located below each of the inclined plates. The nozzles are connected and located below the air ducts. The side frame is located on the side of the drain rack, and the fan is located on the outside of the drain rack. One end of each of the multiple air ducts passes through the side frame and is connected to the output end of the fan. When the instruments are placed on the drain rack for draining, the fan can be turned on, and the output end of the fan will deliver air to the air ducts and blow air downwards from the nozzles to blow air onto the instruments on the drain plate below, thereby accelerating the drying speed of the instruments.
[0008] In a preferred embodiment, the drain rack is equipped with a blower mechanism on the side near the operating table. The blower mechanism includes a fan, a side frame, air ducts, and nozzles. Multiple air ducts are provided and are respectively located below each of the inclined plates. The nozzles are connected and located below the air ducts. The side frame is located on the side of the drain rack, and the fan is located on the outside of the drain rack. One end of each of the multiple air ducts passes through the side frame and is connected to the output end of the fan. When the instruments are placed on the drain rack for draining, the fan can be turned on, and the output end of the fan will deliver air to the air ducts and blow air downwards from the nozzles to blow air onto the instruments on the drain plate below, thereby accelerating the drying speed of the instruments.
[0009] In a preferred embodiment, an annular groove is provided above the soaking tank, and a frame is slidably arranged inside the annular groove. Multiple operating panels are provided, and adjacent operating panels are rotatably connected on one side by a rotating shaft. The two ends of the rotating shaft are engaged and slidably disposed inside the frame. A discharge pipe communicating with the outside is provided on one side of the inside of the soaking tank. During the soaking operation, multiple operating panels can be slid and folded inside the frame, leaving a large space at one end of the frame for staff to place instruments into the soaking tank. When staff need a work surface for operation, they can pull the operating panels inside the frame to one end to unfold them, and then cover the unfolded operating panels and the entire frame with sterile medical cloth, allowing operation to be performed on the sterile cloth, thus increasing the convenience of use for staff.
[0010] In a preferred embodiment, the bottom of the operating panel after it is fully folded and the frame is lowered to its lowest position is above the water level in the soaking tank. By setting the water level of the disinfectant to a low level, the operating panel is prevented from getting contaminated with disinfectant during the folding or lowering of the frame.
[0011] In a preferred embodiment, the frame has symmetrical sliding grooves on both sides, with slots spaced apart within the sliding grooves. An end cap is provided on the end face of the rotating shaft via a first spring. The end cap is slidably engaged with the slots. The distance between adjacent slots is the same as the distance between adjacent rotating shafts. The sliding grooves allow the rotating shafts on the folded operating board to slide freely within them. The engagement of the slots with the end caps ensures that when the operating board is fully unfolded, the rotating shaft end faces on both sides are engaged with the slots, making it difficult for the board to collapse easily, thus guaranteeing the stability of the instrument placed on the operating board.
[0012] In a preferred embodiment, the disinfection rack has a placement plate inside, which is a hollow structure. The placement plate is used to place the strainer. Rollers are provided on both sides below the disinfection rack. The rollers are engaged and slidably disposed in the slide rail. The disinfection rack is located directly above the soaking tank. By pushing the disinfection rack, which holds the cleaned and drained instruments, the disinfection rack can be moved smoothly on the slide rail. It can be directly pushed into the high-temperature disinfection equipment for disinfection, or it can be slid out for unloading and other operations.
[0013] In a preferred embodiment, toothed plates are provided on the lower sides of both ends of the disinfection rack. Gears are rotatably mounted above the operating platform on both ends of the soaking pool, and the gears mesh with the toothed plates. A threaded shaft is provided between the frame and the annular groove. The lower end of the threaded shaft is rotatably mounted above the annular groove. The threaded shaft is driven to rotate by the gears. The upper end of the threaded shaft is threaded through the frame and extends above the frame. When the disinfection rack needs to move above the soaking pool, the toothed plate at one end of the disinfection rack first contacts the gear. The toothed plate moves, driving the gear to rotate, which in turn drives the threaded shaft to rotate. When the threaded shaft rotates, since the frame is threaded outside the threaded shaft, it can drive the frame to move downwards, thereby driving the frame and the operating platform. The materials and instruments placed on the platform are lowered to a certain height to prevent them from being knocked off the operating board when the sterilization rack passes over them. When the sterilization rack moves to the other end of the soaking tank, the toothed plate below the sterilization rack meshes with the gear above the soaking tank at that end, causing it to rotate. This, in turn, causes the threaded shaft to rotate in the opposite direction, realizing the upward movement of the frame. In summary, the threaded shaft is triggered before the sterilization rack passes over the operating board, causing the operating board to descend. After it moves away from the operating board, the threaded shaft is triggered again, causing the operating board to rise and reset the operating board and the instruments placed on it. This saves the labor of staff who would otherwise have to manually remove and put back the instruments on the operating board. The operation is simple and convenient, and the sterilization rack does not directly contact the instruments on the operating board when it passes over them, reducing contamination of the instruments.
[0014] In a preferred embodiment, the two gears located at the same end are linked by a linkage shaft. The threaded shaft is located on one side of the annular groove, and a rack is rotatably mounted on the annular groove on one side of the threaded shaft. The lower end of the rack's sidewall meshes with the lower end of the threaded shaft's sidewall. The threaded shaft or rack is connected to the linkage shaft at the corresponding end in the same way. The linkage shaft at one end of the threaded shaft is linked to the threaded shaft via a first connecting shaft and a second connecting shaft. The first connecting shaft, the second connecting shaft, and the linkage shaft are perpendicular to each other, and their end faces are connected by bevel teeth. The second connecting shaft and the threaded shaft are vertically meshed by bevel gears. When the toothed plate at one end of the disinfection rack meshes with the gear at one end, it sequentially drives the linkage shaft, the first connecting shaft, and the second connecting shaft to rotate, which in turn drives the threaded shaft to rotate, thereby causing the frame to move downward. When the toothed plate meshes with the gear at the other end of the soaking tank, it sequentially drives the linkage shaft, the first connecting shaft, the second connecting shaft, and the rack to rotate. The rack meshes with the threaded shaft, which drives the threaded shaft to rotate in the opposite direction to the previous rotation, thereby realizing the upward operation of the frame and the reset of the frame.
[0015] In a preferred embodiment, the threaded shaft has stops at both its upper and lower ends, and the frame is located between the two stops. The gear has a limiting groove and a limiting ring on its inner side. The two outer ends of the linkage shaft have limiting blocks and ring grooves adapted to the limiting groove and ring. The limiting ring is rotatably engaged within the ring groove. The linkage shaft has an assembly groove on its outer side, and one end of the limiting block is slidably disposed within the assembly groove via a second spring. The outer end of the limiting block is chamfered. By setting two stops at the upper and lower ends of the threaded shaft, the movement range of the frame on the threaded shaft can be limited. Since both ends of the disinfection rack have toothed plates, and gears are also provided on the operating platforms at both ends of the soaking pool, when the front toothed plate of the disinfection rack contacts the first gear, the toothed plate can drive the gear to rotate, thereby driving the threaded shaft to rotate. When the threaded shaft rotates, it directly moves the frame from the top to the bottom, and connects with the bottom... When the stop block contacts the frame, the sterilization rack continues to move forward. When the toothed plate at the rear of the sterilization rack contacts the same gear, since the frame has already moved to the bottom, the gear cannot continue to rotate and drive the frame to move. At this time, the sterilization rack continues to apply moving force, which can cause the limiting groove between the gear and the linkage shaft to disengage from the limiting block. Since the edge of the connection between the limiting block and the limiting groove is chamfered, when sufficient force is applied, the limiting block can squeeze the second spring and retract into the assembly groove. At this time, the limiting groove and the limiting block disengage, the gear can rotate independently, but cannot drive the linkage shaft to rotate, and therefore cannot drive the threaded shaft to rotate. At this time, the sterilization rack can move normally, but the frame will not change. The sterilization rack continues to move. When the front toothed plate of the sterilization rack contacts the gear at the other end, the same principle applies, except that the rotation direction of the threaded shaft is opposite, which can drive the frame to move downward, achieving the effect of resetting the operating panel, but without hindering the normal movement of the sterilization rack.
[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0017] 1. This invention separates the cleaning station from the operating station, preventing water from splashing onto the already cleaned instruments on the operating station during the cleaning process in the cleaning tank, thus effectively reducing contamination. The included drain rack facilitates the drying of the cleaned instruments. A sterilization rack slides directly onto the operating station, and in conjunction with the high-temperature sterilization equipment, instruments can be directly transferred to the sterilization rack after drying. A gentle push of the rack transfers the instruments directly into the high-temperature sterilization equipment. This process eliminates the need for staff to move around, saving labor. Simultaneously, the immersion tank on the operating station facilitates the soaking and sterilization of certain instruments, and the adjustable operating panel allows staff to operate directly from the panel, achieving a multi-functional design and effectively improving space utilization.
[0018] 2. The present invention provides a blower mechanism at one end of the drain rack, which facilitates the drying of instruments placed on the drain rack by blowing air, thereby accelerating the drying speed of the instruments.
[0019] 3. This invention utilizes the engagement of toothed plates at both ends of the disinfection rack with gears at both ends of the soaking pool. Before the disinfection rack passes through the soaking pool, the toothed plate at the front end of the disinfection rack meshes with the gears, causing the gears to rotate, which in turn causes the threaded shaft to rotate. This causes the frame to move downward, thereby lowering the instruments placed on the operating board inside the frame by a certain height, preventing the disinfection rack from colliding with the instruments placed on the operating board when it passes through. After the disinfection rack moves out of the soaking pool, it can cause the threaded shaft to rotate in the opposite direction, causing the frame to move upward, thus achieving automatic reset.
[0020] 4. When performing the soaking operation, multiple operating panels can be slid and folded within the frame, leaving a large space at one end of the frame for staff to place instruments into the soaking tank. When staff need a work surface, they can pull the operating panels within the frame to one end to unfold them, and then cover the unfolded operating panels and the entire frame with sterile medical cloth, allowing them to perform the operation on the sterile cloth, thus increasing the convenience for staff.

Detailed Implementation
[0034] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Example 1
[0036] Please see Figure 1-11This invention provides a technical solution: a sterilization table for instruments used in orthopedic surgery, comprising a washing table 1 and an operating table 2. The end face of the washing table 1 is perpendicular to one side of the operating table 2. A washing pool 3 and a drain rack 4 are respectively provided at both ends of the washing table 1. The drain rack 4 is positioned above the end of the washing table 1 closest to the operating table 2. A soaking pool 5 is located at the center of the operating table 2. An adjustable operating board 6 is located above the soaking pool 5. Slide rails 7 are provided on both sides of the operating table 2. A sterilization rack 9 is slidably mounted on the slide rails 7 above the operating table 2. A high-temperature sterilization device 8 is located at the end of the operating table 2 away from the washing table 1. The inlet of the high-temperature sterilization device 8 is located above the operating table 2. The sterilization rack 9 is slidably placed inside the high-temperature sterilization device 8. After orthopedic surgery, surgical instruments can be uniformly cleaned using the washing table 1. After cleaning, the instruments are placed on the drain rack 4 to drain. Some instruments or equipment require different sterilization processes. For some instruments requiring high-temperature sterilization, such as soaking in chemical disinfectant solutions, medical staff can arrange the instruments to be soaked in the soaking tank 5, add an appropriate amount of disinfectant, and soak for a certain period of time. During the soaking process, the operating board 6 can be adjusted and unfolded above the soaking tank 5, allowing medical staff to perform other operations on the operating board 6, effectively utilizing the operating space. For instruments requiring high-temperature sterilization, after draining and arranging, they are placed on the sterilization rack 9, and then the sterilization rack 9 is pushed along the slide rail 7 until it is pushed into the high-temperature sterilization equipment 8. The inlet of the high-temperature sterilization equipment 8 is then closed, and the equipment is started for high-temperature heating sterilization. During the soaking and sterilization process, staff can perform other operations on the operating board 6 and the cleaning table 1 without obstructing the normal use of the operating table 2 and the cleaning table 1.
[0037] like Figure 1-11 As shown, a drainage channel 10 is provided above the washing platform 1 directly below the drain rack 4. The end of the drainage channel 10 near the washing pool 3 is lower than the other end. The drain rack 4 is provided with a drain plate 111 at intervals inside the upper part. A sloping plate 112 is provided below the drain plate 111. The end of the sloping plate 112 near the washing pool 3 is lower than the other end. The drain plates 111 are engaged and slidably disposed on both sides inside the drain rack 4. After the staff has cleaned the instruments in the washing pool 3, they place them on the drain plate 111 of the drain rack 4. The water drips down onto the sloping plate 112 and then flows down along the sloping plate 112 until it drips down into the drainage channel 10 or the washing pool 3. When placing or removing instruments, the drain plate 111 can be slid off the drain rack 4 for operation, which is quite convenient.
[0038] like Figure 1-11As shown, the drain rack 4 is equipped with a blower mechanism on the side near the operating table 2. The blower mechanism includes a blower 121, a side frame 122, air ducts 123, and nozzles 124. Multiple air ducts 123 are provided and are respectively located below each inclined plate 112. The nozzles 124 are connected and located below the air ducts 123. The side frame 122 is located on the side of the drain rack 4, and the blower 121 is located on the outside of the drain rack 4. One end of the multiple air ducts 123 passes through the side frame 122 and is connected to the output end of the blower 121. When the instruments are placed on the drain rack 4 for draining, the blower 121 can be turned on. The output end of the blower 121 delivers air to the air ducts 123 and blows air downward from the nozzles 124 to blow air onto the instruments on the lower drain plate 111, thereby accelerating the drying speed of the instruments.
[0039] like Figure 1-11 As shown, an annular groove 13 is provided above the soaking tank 5, and a frame 14 is slidably installed inside the annular groove 13. Multiple operating panels 6 are provided, and adjacent operating panels 6 are rotatably connected on one side by a rotating shaft 15. The two ends of the rotating shaft 15 are engaged and slidably installed inside the frame 14. A discharge pipe 16 communicating with the outside is provided on one side of the inside of the soaking tank 5. When performing soaking operations, multiple operating panels 6 can be slid and folded inside the frame 14, leaving a large space at one end of the frame 14 for staff to place instruments into the soaking tank 5. When staff need a table for operation, they can pull the operating panels 6 inside the frame 14 to one end to unfold them, and then cover the unfolded operating panels 6 and the frame 14 with a sterile medical cloth, allowing them to operate on the sterile cloth, which increases the convenience of use for staff.
[0040] like Figure 1-11 As shown, after the control panel 6 is fully folded and the frame 14 is lowered to its lowest position, the bottom of the control panel 6 is above the water level in the soaking tank 5. By setting the water level of the disinfectant to a low level, the control panel 6 is prevented from getting contaminated with disinfectant during the folding of the control panel 6 or the lowering of the frame 14.
[0041] like Figure 1-11 As shown, the frame 14 has symmetrical sliding grooves 171 on both sides inside, and slots 172 are spaced apart in the sliding grooves 171. The end face of the rotating shaft 15 is provided with an end cap 174 through the first spring 173. The end cap 174 is slidably engaged with the slots 172. The distance between adjacent slots 172 is the same as the distance between adjacent rotating shafts 15. The sliding grooves 171 facilitate the free sliding of the rotating shaft 15 on the folded operating plate 6. The slots 172 and end caps 174 are engaged. When the operating plate 6 is fully unfolded, the end faces of the rotating shafts 15 on both sides of the operating plate 6 are engaged with the slots 172, making it difficult for them to collapse easily, thus ensuring the stability of the instrument placed on the operating plate 6.
[0042] like Figure 1-11As shown, the disinfection rack 9 has a placement plate 181 inside. The placement plate 181 has a hollow structure and is used to place the drain plate 111. Rollers 182 are provided on both sides below the disinfection rack 9. The rollers 182 are engaged and slidably set in the slide rail 7. The disinfection rack 9 is located directly above the soaking tank 5. By pushing the disinfection rack 9, which contains cleaned and drained instruments, the disinfection rack 9 can be moved smoothly on the slide rail 7. It can be directly pushed into the high-temperature disinfection equipment 8 for disinfection, or it can be slid out for unloading and other operations.
[0043] like Figure 1-11 As shown, toothed plates 183 are provided on the lower sides of both ends of the disinfection rack 9. Gears 191 are rotatably provided on the upper sides of the operating platform 2 on both ends of the soaking pool 5. The gears 191 mesh with the toothed plates 183. A threaded shaft 192 is provided between the frame 14 and the annular groove 13. The lower end of the threaded shaft 192 is rotatably positioned above the annular groove 13. The threaded shaft 192 is driven to rotate by the gears 191. The upper thread of the threaded shaft 192 passes through the frame 14 and extends to the top of the frame 14. When the disinfection rack 9 needs to move above the soaking pool 5, the toothed plate 183 at one end of the disinfection rack 9 first contacts the gear 191. The toothed plate 183 moves, driving the gear 191 to rotate, which in turn drives the threaded shaft 192 to rotate. When the threaded shaft 192 rotates, since the frame 14 is threaded on the outside of the threaded shaft 192, it can drive the frame 14 to move downward, thereby driving the frame 14 and the operating platform. Materials and instruments placed on the operating plate 6 are lowered to a certain height to prevent the materials on the operating plate 6 from being knocked off when the sterilization rack 9 passes by. When the sterilization rack 9 moves to the other end of the soaking tank 5, the toothed plate 183 below the sterilization rack 9 meshes with the gear 191 above the soaking tank 5 at that end, causing it to rotate, which in turn causes the threaded shaft 192 to rotate in the opposite direction, realizing the upward movement of the frame 14. Therefore, in summary, the threaded shaft 192 is triggered before the sterilization rack 9 passes above the operating plate 6, causing the operating plate 6 to descend. After it moves away from above the operating plate 6, the threaded shaft 192 is triggered again, causing the operating plate 6 to rise, resetting the operating plate 6 and the instruments placed on it. This saves the labor of staff when manually removing and re-placing the instruments on the operating plate 6. The operation is simple and convenient, and the sterilization rack 9 does not directly contact the instruments on the operating plate 6 when it passes by, reducing the contamination of the instruments.
[0044] like Figure 1-11As shown, two gears 191 located at the same end are linked together by a linkage shaft 193. A threaded shaft 192 is located on one side of an annular groove 13. A rack 194 is rotatably mounted on the annular groove 13 on one side of the threaded shaft 192. The lower end of the side wall of the rack 194 meshes with the lower end of the side wall of the threaded shaft 192. The threaded shaft 192 or the rack 194 is connected to the linkage shaft 193 at the corresponding end in the same way. The linkage shaft 193 located at one end of the threaded shaft 192 is linked to the threaded shaft 192 by a first connecting shaft 195 and a second connecting shaft 196. The first connecting shaft 195, the second connecting shaft 196, and the linkage shaft 193 are arranged perpendicularly to each other and their end faces are meshed by bevel gears. The second connecting shaft 196... The toothed plate 183 at one end of the sterilization rack 9 is vertically engaged with the threaded shaft 192 via a bevel gear. When the toothed plate 183 at one end of the sterilization rack 9 engages with the gear 191 at one end, it sequentially drives the linkage shaft 193, the first connecting shaft 195, and the second connecting shaft 196 to rotate, thereby driving the threaded shaft 192 to rotate and causing the frame 14 to move downward. When the toothed plate 183 engages with the gear 191 at the other end of the soaking pool 5, it sequentially drives the linkage shaft 193, the first connecting shaft 195, the second connecting shaft 196, and the rack 194 to rotate. The rack 194 engages with the threaded shaft 192, which drives the threaded shaft 192 to rotate in the opposite direction to the previous rotation, thereby realizing the upward operation of the frame 14 and the reset of the frame 14.
[0045] like Figure 1-11As shown, the threaded shaft 192 has stop blocks 201 at both ends, and the frame 14 is located between the two stop blocks 201. The inner side of the gear 191 has a limiting groove 202 and a limiting ring 203. The outer sides of both ends of the linkage shaft 193 have limiting blocks 205 and annular grooves 204 that are adapted to the limiting grooves 202 and 203. The limiting ring 203 is engaged and rotatably disposed inside the annular groove 204. The outer side of the linkage shaft 193 has an assembly groove 207. One end of the limiting block 205 is slidably disposed in the assembly groove 207 via a second spring 206. The limiting block 205 is disposed on the outer side... One end is chamfered. By setting two stops 201 above and below the threaded shaft 192, the movement range of the frame 14 on the threaded shaft 192 can be limited. Since both ends of the disinfection rack 9 are equipped with toothed plates 183, and the operating tables 2 at both ends of the soaking pool 5 are also equipped with gears 191, when the front toothed plate 183 of the disinfection rack 9 contacts the first gear 191, the toothed plate 183 can drive the gear 191 to rotate, thereby driving the threaded shaft 192 to rotate. When the threaded shaft 192 rotates, it directly moves the frame 14 from the top to the bottom, and it contacts the bottom stop 201. Upon contact, the sterilization rack 9 continues to move forward. When the toothed plate 183 at the rear of the sterilization rack 9 contacts the same gear 191, since the frame 14 has already moved to the bottom, the gear 191 can no longer rotate to drive the frame 14 to move. At this time, the sterilization rack 9 continues to apply moving force, which can cause the limiting groove 202 between the gear 191 and the linkage shaft 193 to disengage from the limiting block 205. Since the edge of the connection between the limiting block 205 and the limiting groove 202 is chamfered, when sufficient force is applied, the limiting block 205 can compress the second spring 206 and retract to the mounting position. Inside the slot 207, the limiting slot 202 disengages from the limiting block 205, and the gear 191 can rotate independently, but cannot drive the linkage shaft 193 to rotate, and thus cannot drive the threaded shaft 192 to rotate. At this time, the disinfection rack 9 can move normally, while the frame 14 remains unchanged. The disinfection rack 9 continues to move. When the front toothed plate 183 of the disinfection rack 9 contacts the gear 191 at the other end, it operates on the same principle as above, except that the rotation direction of the threaded shaft 192 is opposite, which can drive the frame 14 to move downward, achieving the effect of resetting the operating plate 6, but without hindering the normal movement of the disinfection rack 9.
[0046] Example 2
[0047] Based on Example 1, this application provides a mobile automated disposal system for explosive materials, the general concept of which is as follows:
[0048] like Figure 1-11As shown, the frame 14 has symmetrical sliding grooves 171 on both sides inside, and slots 172 are spaced apart in the sliding grooves 171. The end face of the rotating shaft 15 is provided with an end cap 174 through an elastic sheet. The end cap 174 is slidably engaged with the slots 172. The distance between adjacent slots 172 is the same as the distance between adjacent rotating shafts 15. The sliding grooves 171 facilitate the free sliding of the rotating shaft 15 on the folded operating plate 6. The slots 172 and end caps 174 are engaged. When the operating plate 6 is fully unfolded, the end faces of the rotating shafts 15 on both sides of the operating plate 6 are engaged with the slots 172, making it difficult for them to collapse easily, thus ensuring the stability of the instrument placed on the operating plate 6.
[0049] Working Principle: After orthopedic surgery, surgical instruments can be cleaned uniformly through the cleaning station 1. After cleaning, the instruments are placed on the drain rack 4 to drain. Some equipment or instruments require different disinfection methods, such as soaking in chemical disinfectant, while others require high-temperature sterilization. In this case, medical staff can arrange the instruments to be soaked and placed in the soaking tank 5, add an appropriate amount of disinfectant to the soaking tank 5, and soak for a certain period of time. During the soaking process, the operating board 6 can be adjusted and unfolded above the soaking tank 5 to lay flat on top of the soaking tank 5. Medical staff can perform other operations on the operating board 6, effectively utilizing the operating space. For instruments that require high-temperature sterilization, after draining and arranging, they are placed on the sterilization rack 9, and then the sterilization rack 9 is pushed to move on the slide rail 7 until the sterilization rack 9 is pushed into the high-temperature sterilization equipment 8. The inlet of the high-temperature sterilization equipment 8 is closed, and the equipment is started to perform high-temperature heating sterilization. The soaking and sterilization process continues. Staff can perform other operations on the operating board 6 and the cleaning station 1 without hindering the normal use of the operating station 2 and the cleaning station 1.
