Description

Technical Field

[0001] This invention relates to the field of aseptic protection in thoracic surgery, and more specifically to aseptic protection devices for thoracic surgery. Background Technology

[0002] Thoracic surgery (such as open-chest surgery) involves large incisions and prolonged procedures, requiring extremely high standards of sterility; however, traditional surgical environments have the following drawbacks: 1. Due to the long operation time and frequent movement of personnel and instruments, airborne particles and bacteria may contaminate the incision.

[0003] 2. In the same surgery, an instrument may be used in different steps. Therefore, cleaning instruments with sterile solution is a crucial step. It is mainly used to quickly remove bloodstains, tissue residue, or bone cement from instruments during the operation to ensure their normal function and prevent drying and scab formation. Instrument cleaning is usually performed by nurses when the operation is not too busy. In emergency situations, when there is a shortage of manpower, it is difficult to clean the joints of instruments. If multiple instruments are cleaned at the same time, they are prone to collision and wear, which has a significant impact on the durability of precision equipment that costs thousands of dollars.

[0004] Surgical forceps are frequently used instruments in thoracic surgery, and multiple types of surgical forceps are usually used in combination. If the problem of cleaning surgical forceps during surgery can be solved, the sterile environment of the surgery can be further guaranteed.

[0005] Therefore, there is a need for a sterile device for thoracic surgery that can clean instruments in batches while avoiding collisions and abrasions during cleaning. Summary of the Invention

[0006] The present invention aims to provide a sterile device for thoracic surgery, which can clean instruments in batches while avoiding collision and wear during cleaning.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a sterile surgical device for thoracic surgery, comprising a sterile cleaning box, wherein the sterile cleaning box is provided with a cleaning component, a driving component, and a supporting component. The cleaning component is disposed on both sides of the supporting component. The supporting component is used to support the surgical forceps. The supporting component includes a first supporting rod and a second supporting rod arranged horizontally and parallel to each other. The first supporting rod is provided with a plurality of first limiting parts along its length direction, and the second supporting rod is provided with a plurality of second limiting parts along its length direction. The first supporting rod and the second supporting rod respectively pass through two finger rings of the surgical forceps; the cleaning component is used to rinse the surgical forceps. In the initial state, the first limiting part and the second limiting part are positioned opposite each other, and the two finger rings of the surgical forceps are perpendicular to the first support rod; The drive assembly is used to drive the second support rod closer to the first support rod, thereby causing the first limiting part and the second limiting part to be misaligned, and the two finger rings of the surgical forceps to tilt relative to the first support rod.

[0008] The beneficial effects of this plan are: 1. Although there are different types of surgical forceps, the size specifications of the finger ring positions are similar. Even though the requirements for the opening range of the ends of surgical forceps are different, the spacing between the two finger rings can meet the requirements with two sizes. Therefore, a set of devices can be designed to be applicable to most surgical forceps.

[0009] In this invention, the finger ring is suspended by two support rods passing through it, so as to facilitate the rinsing of the surgical forceps; To prevent collisions between the surgical forceps during rinsing, rinsing is performed from both sides of the support rod. The surgical forceps sway in a direction perpendicular to the support rod, while the forceps are arranged along the length of the support rod, thus minimizing the risk of collisions. 2. Because rinsing along the length of the support rod is difficult, in this design, the drive assembly is used to move the second support rod closer to the first support rod and misalign the first and second limiting parts, thereby causing the surgical forceps to rotate. This facilitates cleaning of the remaining two sides of the forceps, preventing them from colliding even under water pressure. Thoracic surgical forceps are often precision, high-value instruments, and frequent replacement or repair is extremely costly. This device, through non-contact, isolated cleaning, significantly extends instrument life and reduces hospital operating costs, making it particularly suitable for thoracic surgeries where instrument reliability is paramount.

[0010] 3. In existing technologies, nurses are responsible for cleaning instruments. However, in thoracic surgical emergencies (such as massive bleeding), medical staff must focus on resuscitation and cannot be distracted by cleaning instruments, making it difficult to clean the joints of the instruments. This solution, through a drive component, achieves automatic misalignment of surgical forceps, automatic opening and closing of joints, and automatic rinsing. It can automatically execute the cleaning process, ensuring that instruments are restored to a sterile state in the shortest possible time, reducing the need for manpower and ensuring the continuity of surgery.

[0011] 4. Conventional static irrigation can only clean a portion of the surface. Thoracic surgery is lengthy and involves large incisions, increasing the risk of serious infection. This solution utilizes an active misalignment mechanism to change the posture of the surgical forceps during irrigation, ensuring that the water flow covers all surfaces, including joint gaps and the inner side of the finger ring. Furthermore, the first limiting part includes a first protrusion, and the second limiting part includes a second protrusion. The finger ring is hung between adjacent first protrusions on the first support rod or between adjacent second protrusions on the second support rod. In the initial state, both the first and second protrusions face downwards, and at this time, both the first and second protrusions can pass through the finger ring of the surgical forceps; The drive assembly is used to drive the second support rod and the first support rod to rotate, so that the first protrusion and the second protrusion face upward or to the side; so that the first protrusion and the second protrusion can move the ring together.

[0012] Furthermore, the drive assembly includes a moving unit, which includes a moving motor, a threaded rod, a guide rod, a moving block, and at least two lifting rods. The threaded rod and the guide rod are arranged in parallel. The threaded rod is rotatably disposed inside the sterile cleaning chamber, and the guide rod is fixed inside the sterile cleaning chamber. The output shaft of the moving motor is connected to the end of the threaded rod. The threaded rod passes through the moving block and is threadedly connected to the moving block. The guide rod passes through the moving block and is slidably connected to the moving block. A vertical through-hole is opened on the moving block. The through-hole is parallel to the first support rod, and the guide rod is perpendicular to the through-hole. The lifting rod passes through the through-hole and has an end head at the upper end, which is located on the upper side of the moving block. The through-hole restricts the end head from passing through. The upper inner surface of the sterile cleaning box is provided with a guide groove, and the end is accommodated in the guide groove. The moving block drives the end to move in the guide groove.

[0013] Furthermore, the guide groove includes straight sections and curved sections; The arc-shaped segment is used to guide the second support rod when it is driven closer to the first support rod, causing the first limiting part and the second limiting part to be misaligned; The straight segment is used to guide the second support rod away from the first support rod and separate the two rings of the surgical forceps.

[0014] Furthermore, the drive assembly includes a rotating unit, which includes a rotary motor, a first gear, and a second gear. The output shaft of the rotary motor is keyed to the first gear or the second gear, and the first gear and the second gear mesh. The first gear and the second gear are respectively connected to the ends of the first support rod and the second support rod.

[0015] Furthermore, the first gear is provided with a first connecting part, the first connecting part is provided with a first rectangular groove, the end of the first support rod is provided with a first rectangular part, the first rectangular part is used to insert into the first rectangular groove and to have a clearance fit with the first rectangular groove; the second gear is provided with a second connecting part, the second connecting part is provided with a second rectangular groove, the second rectangular groove extends in the length direction to connect with the edge of the connecting part, the end of the second support rod is provided with a second rectangular part, the second rectangular part is used to insert into the second rectangular groove, and the second rectangular part and the second rectangular groove have a clearance fit in the width direction.

[0016] Furthermore, the lower end of the boom is provided with an arc-shaped groove, which engages with the second support rod. When the moving motor drives the second support rod to rotate, it can overcome the friction after engagement and rotate. It also includes a support frame, which includes a support column and an L-shaped component. The upper end of the support column is provided with two fixing holes. The lower surfaces of the first and second support rods are both provided with fixing columns. The fixing columns are used to insert into the fixing holes and rotate horizontally with the fixing holes. The fixing holes and fixing columns are clearance-fitted, and the clearance between the fixing holes and fixing columns allows the first and second support rods to rotate vertically within a small range. The L-shaped component includes a horizontal rod, and the lower surface of the horizontal rod is provided with two small grooves. The small grooves are used to limit the ends of the first and second support rods. When the first support rod is installed on the support frame, one end of the first rectangular part contacts the small groove of the horizontal rod, and several first protrusions are arranged downward between the other end of the first rectangular part and the fixed column. When the second support rod is installed on the support frame, one end of the second rectangular part contacts the small groove of the horizontal rod, and several second protrusions are arranged downward between the other end of the second rectangular part and the fixed column. The first and second support rods are parallel, and the distance between the first and second support rods matches the distance between the two finger rings of the surgical forceps.

[0017] Furthermore, it includes an operating table and a mobile cart, with a cleaned instrument table and a used instrument table on the side of the operating table; In the initial state, the support frame is placed on the instrument table that has been used, the sterile cleaning box is placed on the cleaning cart, the cleaning cart is on the side of the instrument table that has been used, and the sterile cleaning box has a first door on the side closer to the instrument table that has been used, and a second door on the side farther away from the instrument table that has been used. After the support rod of the support frame is placed into the sterile cleaning box through the first box door, the cleaning cart has a second box door on the side away from the instrument table that has been used. After the sterile cleaning box is cleaned, the cleaning trolley approaches the cleaned instrument table, and the support rod and surgical forceps are taken out from the second box door. The surgical forceps are placed on the cleaned instrument table, and the support rod is placed on the support frame of the used instrument table.

[0018] This solution also has the following effects: 1. During the surgery, the support frame is placed next to the operating table. The fixing posts of the first and second support rods are inserted into the fixing holes. The ends of the first and second support rods are rotated to below the horizontal bar of the L-shaped component, and the ends of the first and second support rods are limited by small grooves. The surgeon places the used surgical forceps on the first and second support rods, with the first and second protrusions facing downwards, which will not affect the sliding of the surgical forceps on the support rods. The L-shaped component can be designed with an adjustable height as needed. After use, the surgical forceps can be placed directly on the support rods. During the instrument turnover during surgery, nurses do not need to handle each instrument individually; they only need to hang the used instruments on the support frame, and after a certain number have accumulated, they are sent to the washing box as a whole. This modular turnover method greatly shortens the time instruments are off the table, meeting the high-intensity, fast-paced surgical needs of thoracic surgery.

[0019] 2. Rotate and remove the first support rod, the second support, and the surgical forceps from the support frame. Insert the ends of the first and second support rods into the first and second rectangular slots, respectively. Snap the second support rod and the two hanging rods together so that the hanging rods can drive the second support rod to rotate. Clean both sides of the surgical forceps using the cleaning assembly. At this time, the two finger rings of the surgical forceps are perpendicular to the first support rod.

[0020] 3. The drive assembly is used to drive the second support rod closer to the first support rod. Before the second support rod approaches the first support rod, the rotary motor drives the two suspension rods to rotate, rotating the first protrusion of the first support rod to the side away from the second support rod, and rotating the second protrusion of the second support rod to the side away from the first support rod. At this time, neither the first nor the second protrusion can pass through the finger ring. Therefore, when the second support rod is driven closer to the first support rod, the first and second protrusions are misaligned. The first and second protrusions drive the finger rings to misalign as well, thereby causing the surgical forceps to rotate until the two support rods clamp the surgical forceps. The two finger rings of the surgical forceps are tilted relative to the first support rod to facilitate cleaning of the remaining two sides of the surgical forceps.

[0021] 4. By driving the second support rod away from the first support rod, the two rings of the surgical forceps are moved away, thereby opening the joint of the surgical forceps to facilitate cleaning.

[0022] 5. The lengths of the arms of different surgical forceps may vary. The distance between the two rings is determined by the shortest arm length, that is, the distance between the rings should be as large as possible while ensuring that all surgical forceps can be opened.

[0023] 6. By installing the sterile cleaning box on a mobile cart, and placing used and cleaned instrument tables next to the operating table, a closed-loop intraoperative turnover system of "dirty instrument collection—cleaning—clean instrument return" is established. Dirty instruments enter through the first door, and clean instruments are taken out through the second door, achieving physical isolation and preventing cross-contamination. The cleaning cart can be equipped with a built-in motor for mobility, so nurses do not need to run around; they can simply wait beside the operating table for the cleaning cart to approach the used and cleaned instrument tables before performing the procedure.

Detailed Implementation

[0025] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: sterile cleaning box 1, first door 11, threaded rod 12, guide rod 13, moving block 14, strip hole 15, hanging rod 16, end 17, clearance notch 18, fixing rod 19, support frame 2, base 21, support column 22, fixing hole 23, upright 24, horizontal rod 25, surgical forceps 3, finger ring 31, spray head 4, support rod 5, first support rod 51, second support rod 52, first protrusion 53, second protrusion 54, first rectangular part 55, second rectangular part 56, fixing column 57, guide groove 6, straight segment 61, arc segment 62, rotary motor 71, first gear 72, second gear 73, first connecting part 74, second connecting part 75, second rectangular groove 76, operating table 81, sterile instrument table 82, cleaned instrument table 83, used instrument table 84, moving trolley 85, second door 86.

[0026] Example 1 Example 1 is basically as follows Figures 1-8The device shown is a sterile operating room for thoracic surgery, particularly suitable for high-frequency instrument turnover scenarios in thoracic surgery. The surgeon simply hangs the used surgical forceps on a support frame. During surgical breaks or when a certain number have accumulated, the entire device is placed into a sterile cleaning box, where the system automatically completes the cleaning process. The entire process requires no manual contact, ensuring sterility and freeing up medical staff. The device includes a sterile cleaning box 1 and a support frame 2. The sterile cleaning box 1 includes a support assembly, which is shared by both the sterile cleaning box 1 and the support frame 2. The support frame 2 is placed beside the operating table 81 to facilitate placing used surgical forceps 3 on the support assembly of the support frame 2. Then, the support assembly and the surgical forceps 3 are placed together into the sterile cleaning box 1 for cleaning. This embodiment can automatically clean the surgical forceps 3 during surgery, saving manpower and also facilitating the cleaning of surgical forceps 3 used in robotic surgery, thus promoting the development of robotic surgical equipment.

[0027] like Figure 1 , Figure 2 As shown, the sterile cleaning box 1 is equipped with a cleaning component, a drive component, and a support component. The cleaning equipment is not shown in the figure. The cleaning equipment is set on both sides of the support component, that is, the front and rear sides in the figure. The cleaning equipment adopts existing cleaning equipment, including water pipes. Several spray heads 4 are provided on the water pipes to facilitate the use of sterile cleaning solution to rinse the surgical forceps 3. The inventive point of this embodiment is not in the structure of the cleaning equipment, but in clarifying the rinsing direction and position.

[0028] For ease of observation, Figure 1 The front side wall of the sterile cleaning box 1 and the first box door 11 on the right side are hidden inside. The first box door 11 is opened to facilitate the placement of the support assembly and surgical forceps 3 into the box.

[0029] The support assembly includes a first support rod 51 and a second support rod 52 arranged horizontally and parallel to each other. The first support rod 51 has several first limiting portions along its length, such as... Figure 2 As shown, the first limiting part includes a downwardly oriented first protrusion 53, and a limiting groove with a small arc (not shown in the figure) is provided between adjacent first protrusions 53, thereby providing auxiliary positioning for the finger ring 31 of the surgical forceps 3. That is, when the finger ring 31 is pushed to slide on the first support rod 51 through the limiting groove, the vibration of the finger ring 31 can be felt, but as long as force is applied, the finger ring 31 can be pushed away from the limiting groove. If the first support rod 51 is tilted more than 5°, the surgical forceps 3 can easily cross the limiting groove under the action of gravity.

[0030] Similarly, the second support rod 52 is provided with a number of second limiting parts along the length direction. In the initial state, the first limiting part and the second limiting part are positioned opposite each other. The second limiting part includes a second protrusion 54 that is set downwards. A limiting groove with a small arc (not shown in the figure) is also provided between adjacent second protrusions 54. This limiting groove is the same as the limiting groove on the first support rod 51.

[0031] The first support rod 51 and the second support rod 52 pass through the two rings 31 of the surgical forceps 3 respectively; one ring 31 is hung between the adjacent first protrusions 53 on the first support rod 51, and the other ring 31 is hung between the adjacent second protrusions 54 on the second support rod 52.

[0032] like Figure 1 , Figure 2 As shown, the drive assembly includes a moving unit and a rotating unit. The moving unit includes a moving motor, a threaded rod 12, a guide rod 13, a moving block 14, and two lifting rods 16. The threaded rod 12 and the guide rod 13 are arranged in parallel. The moving motor and... Figure 2 The bolt connection is located at the upper left rear corner of the sterile cleaning box 1. Figure 2 (Not shown in the image), the output shaft of the moving motor is keyed to the rear end of the threaded rod 12. The front end of the threaded rod 12 is inserted into the side wall of the sterile cleaning box 1 and rotatably connected to the sterile cleaning box 1. Both ends of the guide rod 13 are bolted to the sterile cleaning box 1. The threaded rod 12 passes through the moving block 14 and is threadedly connected to the moving block 14. The guide rod 13 passes through the moving block 14 and is slidably connected to the moving block 14. Figure 6 As shown, the movable block 14 has a vertical through-hole 15, which is parallel to the first support rod 51. The guide rod 13 is perpendicular to the through-hole 15. Both hanging rods 16 pass through the through-hole 15. The upper end of the hanging rod 16 is integrally formed with a disc-shaped end 17, which is located on the upper side of the movable block 14. The through-hole 15 restricts the end 17 from passing through. The lower end of the hanging rod 16 has an arc-shaped groove for engaging with the second support rod 52. The angle of the arc-shaped groove is greater than 180°.

[0033] The upper inner surface of the sterile cleaning box 1 is bolted with a fixing rod 19. The lower end of the fixing rod 19 is also opened with an arc-shaped groove. The arc-shaped groove is used to engage with the first support rod 51. The moving block 14 is provided with a clearance notch 18 at the corresponding position to prevent it from colliding with the fixing rod 19 when moving. The upper inner surface of the sterile cleaning box 1 has a guide groove 6, and the end 17 is accommodated in the guide groove 6. The moving block 14 drives the end 17 to move within the guide groove 6, such as... Figure 7 As shown, the guide groove 6 includes a straight section 61 and an arc section 62. The straight section 61 is perpendicular to the first support rod 51. The arc section 62 is used to guide the second support rod 52 when it moves closer to the first support rod 51 and causes the first limiting part and the second limiting part to be misaligned. The straight section 61 is used to guide the second support rod 52 when it moves away from the first support rod 51 and separates the two rings 31 of the surgical forceps 3.

[0034] like Figure 2 , Figure 6As shown, the rotating unit includes a rotating motor 71, a first gear 72, and a second gear 73. The rotating motor 71 is embedded in the side wall of the sterile cleaning box 1, that is, a motor cavity is opened in the side wall of the sterile cleaning box 1. The rotating motor 71 is bolted to the motor cavity. The output shaft of the rotating motor 71 passes through the side wall and is keyed to the first gear 72. The first gear 72 and the second gear 73 mesh. The first gear 72 and the second gear 73 are respectively connected to the ends of the first support rod 51 and the second support rod 52.

[0035] like Figure 6 As shown, the first gear 72 has a first connecting part 74 integrally formed on the left side, and a first rectangular groove is formed on the left side of the first connecting part 74. Figure 6 (Not shown in the text), such as Figure 1 As shown ( Figure 1 and Figure 6 (Due to different angles, the left and right sides are also opposite). The left end of the first support rod 51 is integrally formed with a first rectangular portion 55. The first rectangular portion 55 is used to insert into the first rectangular groove and to fit with the first rectangular groove with a clearance. Figure 6 As shown, a second connecting portion 75 is integrally formed on the second gear 73. A second rectangular groove 76 is formed on the left side of the second connecting portion 75, extending in the length direction to connect with the upper edge of the connecting portion. A second rectangular portion 56 is integrally formed on the right end of the second support rod 52. The second rectangular portion 56 is used to insert into the second rectangular groove 76. The second rectangular portion 56 and the second rectangular groove 76 are clearance-fitted in the width direction. The clearance between the second rectangular portion 56 and the second rectangular groove 76 does not hinder the second rectangular portion 56 from moving out of the second rectangular groove 76 along the trajectory of the arc groove. The height of the second rectangular portion 56 is less than the height of the second rectangular groove 76. When the moving motor drives the first support rod 51 and the second support rod 52 to rotate, it can overcome the friction after the engagement and rotate.

[0036] like Figure 8 As shown, the support frame 2 includes a base 21, on which a support column 22 and an L-shaped component are bolted. The upper surface of the support column 22 has two fixing holes 23 (only one is shown in the figure). The lower surfaces of the first support rod 51 and the second support rod 52 are both integrally formed with fixing columns 57. The fixing columns 57 are used to insert into the fixing holes 23 and are horizontally rotatably connected to the fixing holes 23. The fixing holes 23 and the fixing columns 57 are clearance-fitted. The upper cross-sectional radius of the fixing holes 23 is larger than the lower cross-sectional radius, that is, the clearance between the fixing holes 23 and the fixing columns 57 allows the first support rod 51 and the second support rod 52 to rotate vertically within a small range. The L-shaped component includes a vertical rod 24, the lower end of which is bolted to the base 21. The upper end of the vertical rod 24 is integrally formed with the rear end of the horizontal rod 25. The lower surface of the horizontal rod 25 is provided with two small grooves, which are used to contact and limit the contact of the ends of the first support rod 51 and the second support rod 52.

[0037] The method for using the aseptic protection device for thoracic surgery is as follows: 1. During the operation, the support frame 2 is placed next to the operating table 81. The fixing posts 57 of the first support rod 51 and the second support rod 52 are inserted into the fixing holes 23. The ends of the first support rod 51 and the second support rod 52 are rotated to be below the horizontal bar 25 of the L-shaped component. Under the action of gravity, the left end of the first support rod 51 and the second support rod 52 descends and the right end rises. The right end of the first support rod 51 and the second support rod 52 is limited by the small groove. At this time, the first protrusion 53 and the second protrusion 54 face downwards. The doctor places the used surgical forceps 3 on the first support rod 51 and the second support rod 52.

[0038] 2. Rotate and remove the first support rod 51, the second support, and the surgical forceps 3 from the support frame 2. Insert the ends of the first support rod 51 and the second support rod 52 into the first rectangular slot and the second rectangular slot 76, respectively. Engage the second support rod 52 with the two suspension rods 16 so that the suspension rods 16 can drive the second support rod 52 to rotate. Figure 3 As shown, the surgical forceps 3 are cleaned using the cleaning component.

[0039] 3. For example Figure 4 As shown, before the drive assembly drives the second support rod 52 to approach the first support rod 51, the rotary motor 71 drives the two hanging rods 16 to rotate, rotating the first protrusion 53 of the first support rod 51 to the side away from the second support rod 52, and rotating the second protrusion 54 of the second support rod 52 to the side away from the first support rod 51. At this time, neither the first protrusion 53 nor the second protrusion 54 can pass through the ring 31. Therefore, when the second support rod 52 is driven to approach the first support rod 51, when the first protrusion 53 and the second protrusion 54 are misaligned, the first protrusion 53 and the second protrusion 54 drive the ring 31 to misalign as well, thereby causing the surgical forceps 3 to rotate until the two support rods 5 clamp the surgical forceps 3, so as to facilitate cleaning the remaining two sides of the surgical forceps 3.

[0040] 4. For example Figure 5 As shown, by driving the second support rod 52 away from the first support rod 51, the two rings 31 of the surgical forceps 3 are moved away, thereby opening the joint of the surgical forceps 3 for easy cleaning.

[0041] Example 2 The difference between Embodiment 2 and Embodiment 1 is that the straight section 61 of the guide groove 6 is inclined relative to the first support rod 51 so as to drive the surgical forceps 3 to rotate so as to wash the side of the surgical forceps 3 that was originally perpendicular to the first support rod 51.

[0042] Example 3 like Figure 10As shown, in the prior art, an instrument table is usually placed next to the operating table 81 for placing instruments. The instrument table is further divided into sections according to the sterility of the instruments: sterile instruments, cleaned instruments, and used instruments. Sterile instruments become used instruments after use, used instruments become cleaned instruments after cleaning, and cleaned instruments become used instruments after use.

[0043] Example 3 is based on Example 2: It includes an operating table 81 and a mobile cart 85. The left side of the operating table 81 is a sterile core area, and the right side of the operating table 81 is equipped with an instrument table, which includes a sterile instrument table 82, a cleaned instrument table 83, and a used instrument table 84. The sterile instruments, cleaned instruments, and used instruments are placed on the sterile instrument table 82, the cleaned instrument table 83, and the used instrument table 84, respectively. The nurse stands between the operating table 81 and the instrument table.

[0044] In the initial state, the support frame 2 is placed on the used instrument table 84, and the sterile cleaning box 1 is placed on the cleaning cart, which is located to the side of the used instrument table 84. The first door 11 is located on the left side of the sterile cleaning box 1, and the second door 86 is located on the right side of the sterile cleaning box 1. The relative positions of the first door 11 and the second door 86 are as follows: Figure 14 As shown, the cleaning cart is equipped with wheels on its underside. The wheels are used to drive the cleaning cart to move or turn.
