Surgical Instrument Cart

[0041] Therefore, a large number of surgical instruments are required during the process of medical surgery, such as scalpels, surgical forceps, sterile drapes, etc. Before these surgical instruments enter the operating room, they are usually stored in a dedicated area outside the operating room or in an equipment storage room. The design and management of these areas or equipment storage rooms follow strict specifications and standards to ensure the safety, sterility, and ready availability of surgical instruments.

[0042] In the prior art, the instrument nurse (surgical department nurse) enters the operating room in advance before the surgery, prepares the required surgical instruments and items according to the habits of the surgeon in charge, and checks whether the surgical items are complete and applicable. When omissions are found, they are supplemented in a timely manner; the instrument nurse uses a conventional trolley to transport the prepared surgical instruments to the operating room to complete the preoperative preparation work.

[0043] However, the conventional trolley has a low degree of intelligence and must be manually controlled to be pushed to the operating room; and most conventional trolleys are of an open structure. Therefore, in order to ensure the safety of surgical instruments, the surgical instruments need to be wrapped with sterile drapes before being transported to the operating room, lacking necessary safety protection means.

[0044] Therefore, the present application provides a surgical instrument cart 1000. Please refer to Figure 1 , the surgical instrument cart 1000 is used in hospitals. The surgical instrument cart 1000 has an intelligent setting and can transport surgical instruments to target locations, such as operating rooms, emergency medical rooms, etc. The surgical instruments transported by the surgical instrument cart 1000 include but are not limited to scalpels, surgical forceps, metal trays, sterile drapes, etc. The surgical instrument cart 1000 can achieve automatic pathfinding and the function of sealing surgical instruments.

[0045] In one embodiment, please refer to Figure 1The surgical instrument cart 1000 includes a chassis structure 100 and a loading structure 200, wherein the loading structure 200 is fixed to the chassis structure 100.

The magnetic attraction member 231 is arranged on the loading frame 210, and the mating member 232 is arranged on the storage cabinet 220. In the locked state R1, the magnetic attraction member 231 cooperates with the mating member 232 to be fixed. In the unlocked state R2, the mating member 232 is separated from the magnetic attraction member 231.

[0080] In a specific embodiment, the switching between the locked state R1 and the unlocked state R2 of the storage cabinet 220 is realized through the magnetic attraction mechanism 230. The magnetic attraction member 231 may include a coil, and the mating member 232 may be made of iron. By energizing the coil to generate magnetic force, after the mating member 232 approaches the coil, the coil tightly attracts the mating member 232 to achieve locking; then by cutting off the power of the coil, the magnetic force disappears, the mating member 232 is not attracted by the magnetic attraction member 231, and the mating member 232 can be separated from the magnetic attraction member 231. The setting method of the electromagnet is technically mature, with a fast response speed, and can reduce mechanical kinetic energy.

[0081] In a specific embodiment, the magnetic attraction member 231 may also be a magnet (permanent magnet), and the mating member 232 may be made of iron or another magnet of opposite polarity. After the mating member 232 approaches the magnetic attraction member 231, the magnetic attraction member 231 tightly attracts the mating member 232 to achieve locking; then through other mechanical structures (such as motors, physical buttons, etc.), the magnetic attraction member 231 is peeled off from the mating member 232, and the mating member 232 is not attracted by the magnetic attraction member 231 to achieve unlocking. The setting method of the permanent magnet can reduce the electromagnetic structure and lower the cost of the magnetic attraction structure.

[0082] In one implementation, please refer to Figure 8 , the magnetic attraction member 231 is arranged on the loading frame 210, and is specifically located at the opening of the storage space 211; the mating member 232 is arranged on the storage cabinet 220, and is specifically located on the door panel 223 of the storage cabinet 220. Specifically, the housing 212 includes a housing plate 2121. The housing plate 2121 includes the side surfaces mentioned above. An opening is formed on the housing plate 2121, and this opening is the opening communicating with the storage space 211. In the locked state R1, the door panel 223 and the housing plate 2121 are connected, so as to ensure that a sealed space is formed inside. The magnetic attraction member 231 is installed on the housing plate 2121.

[0083] In a specific embodiment, please refer to Figure 8, the shell plate 2121 forms a boss 2122 protruding from the inner wall at the inner wall of the opening, so that the shell plate 2121 forms a step at the opening. The boss 2122 includes a step surface, the step surface is parallel to the side surface and is located behind the side surface. The door panel 223 includes an inner surface and an outer surface facing away from each other. The inner surface faces the step surface and is connected to the step surface in the locked state R1. The outer surface faces the same direction as the side surface and jointly forms the surface of the loading structure 200 with the side surface in the locked state R1.

[0084] In a specific embodiment, the magnetic member 231 is disposed on the boss 2122 and is exposed on the step surface, and the mating member 232 is disposed on the door panel 223 and is exposed on the inner surface. Because after the storage cabinet 220 is inserted into the storage space 211, the boss 2122 is connected and cooperated with the door panel 223, so as to achieve the functions of sealing and limiting. Utilizing the characteristics that the step surface and the inner surface face each other, the orthographic projection of the mating member 232 on the step surface at least covers the magnetic member 231, and the mating member 232 moves towards the magnetic member 231, and positive attraction is realized by the opposite movement.

[0085] In a specific embodiment, the magnetic member 231 is disposed at the opening of the shell plate 2121 and is exposed on the inner wall surface of the opening, and the mating member 232 is disposed on the door panel 223 and is exposed on the side surface of the door panel 223. It can be understood that in the locked state R1, the side surface of the door panel 223 is in contact with the inner wall surface of the opening, so this place can be set as the connection point of the magnetic member 231 and the mating member 232.

[0086] In one embodiment, the magnetic member 231 is disposed in the loading frame 210 and is exposed in the storage space 211, and the mating member 232 is disposed on the storage cabinet 220, and is specifically located on the side plate 222 of the storage cabinet 220. Specifically, the support member 213 includes an inner space wall plate 2133, and the inner space wall plate 2133 is used to enclose the accommodation space. In the locked state R1, the inner space wall plate 2133 is disposed outside the side plate 222.

[0087] In a specific embodiment, the inner space wall plate 2133 includes a part facing the opening of the shell plate 2121, and the magnetic member 231 is disposed on the part of the inner space wall plate 2133 facing the opening of the shell plate 2121 and is exposed in the storage space 211. The storage cabinet 220 includes a rear side plate 222 disposed opposite and spaced apart from the door panel 223, and the mating member 232 is disposed on the rear side plate 222. Utilizing the characteristics that the rear side plate 222 and the inner space wall plate 2133 face each other, the orthographic projection of the mating member 232 on the inner space wall plate 2133 at least covers the magnetic member 231, and the mating member 232 moves towards the magnetic member 231, and positive attraction is realized by the opposite movement.

[0088] In a specific embodiment, the magnetic attraction member 231 is disposed on the inner space wall panel 2133 and is located on the left or right side of the storage cabinet 220. The storage cabinet 220 includes a left side panel and a right side panel connected to the door panel 223, and the mating member 232 is disposed on the left side panel or the right side panel. Alternatively, the magnetic attraction member 231 is disposed on the inner space wall panel 2133 and is located below the storage cabinet 220. The mating member 232 is disposed on the bottom plate 221. It can be understood that in the locked state R1, both the side plate 222 and the bottom plate 221 of the storage cabinet 220 are located in the inner space wall panel 2133, so the connection points of the magnetic attraction member 231 and the mating member 232 can be set here.

[0089] In one embodiment, the magnetic attraction member 231 is an electromagnetic attraction member 231, and the magnetic attraction member 231 is electrically connected to the controller 140. The controller 140 controls the circuit in the magnetic attraction member 231 to conduct or turn off, so that the magnetic attraction member 231 has magnetism or the magnetism disappears. In this way, the effect of switching between the unlocked state R2 and the locked state R1 is achieved.

[0090] In one embodiment, please refer to Figure 6 and Figure 8 , the loading structure 200 includes an ejection mechanism 240. The ejection mechanism 240 is disposed between the loading frame 210 and the storage cabinet 220. The ejection mechanism 240 includes a trigger assembly 241 and an elastic member 242 connected to each other. The trigger assembly 241 is connected to the storage cabinet 220, and the elastic member 242 is disposed on the loading frame 210. In the locked state R1, the trigger assembly 241 drives the elastic member 242 to undergo elastic deformation. During the process of switching to the unlocked state R2, the elastic member 242 resumes its original shape and reversely drives the trigger assembly 241 to drive the storage cabinet 220 to slide horizontally.

[0091] In a specific embodiment, the storage cabinet 220 can automatically eject the loading frame 210. Part of the trigger assembly 241 is disposed on the storage cabinet 220, and part of it can also be disposed on the loading frame 210. The two parts of the trigger assembly 241 drive the elastic member 242 to undergo elastic deformation through the mechanical force in contact, so that the elastic member 242 has the elastic potential energy to resume its original shape. The elastic member 242 can include a spring, and the type of the spring is not limited.

[0092] In a specific embodiment, during the process of switching from the unlocked state R2 to the locked state R1, the trigger assembly 241 generates a mechanical force and then causes the elastic member 242 to undergo elastic deformation; until the locked state R1, the magnetic attraction mechanism 230 is activated, the magnetic attraction member 231 and the mating member 232 attract each other, and the elastic member 242 cannot resume its original shape. During the process of switching to the unlocked state R2, the magnetic attraction mechanism 230 is turned off, the magnetic attraction member 231 and the mating member 232 cannot attract each other, the elastic member 242 resumes its original shape and causes the storage cabinet 220 to eject.

[0093] In one embodiment, please refer toFigure 8 When triggered, the triggering assembly 241 includes a push rod 2411, a rotating rod 2412, and a rotating shaft 2413. The push rod 2411 is disposed on the side surface of the storage cabinet 220, the rotating shaft 2413 is disposed on the inner wall of the accommodation space, the rotating rod 2412 is rotatably connected to the rotating shaft 2413, one end of the rotating rod 2412 contacts the push rod 2411, and the other end of the rotating rod 2412 is connected to the elastic member 242. The push rod 2411 pushes the rotating rod 2412 to rotate, and the rotating rod 2412 drives the elastic member 242 to undergo elastic deformation.

[0094] In a specific embodiment, one push rod 2411 is provided on each of the left side plate and the right side plate of the storage cabinet 220, for a total of two push rods 2411. The push rod 2411 is cylindrical and protrudes from the wall surface of the left side plate or the right side plate. The push rods 2411 on the left side plate and the right side plate can be symmetrically arranged; the number of the triggering assemblies 241 is also two groups, which are respectively corresponding to the push rods 2411 on the left side plate and the right side plate.

[0095] In a specific embodiment, please refer to Figure 9 and Figure 10 Taking the push rod 2411 on the left side plate as an example, the push rod 2411 extends along the first direction X. A triggering space 2134 is formed on the (left) inner space wall plate 2133. The rotating shaft 2413 is received in the triggering space 2134 and extends along the first direction X; the rotating rod 2412 is received in the triggering space 2134, and the middle part of the rotating rod 2412 is rotatably connected to the rotating shaft 2413. A sliding groove 2135 is formed on the surface of the inner space wall plate 2133 facing the left side plate. The sliding groove 2135 is used to communicate the triggering space 2134 and the storage space 211. The sliding groove 2135 extends along the second direction Y, and the push rod 2411 extends into the sliding groove 2135 and is connected to one end of the rotating rod 2412.

[0096] In a specific embodiment, please refer to Figure 8 The first direction X and the second direction Y are perpendicular, and the second direction Y is the direction in which the storage cabinet 220 is inserted or withdrawn. The function of the sliding groove 2135 is to enable the push rod 2411 to be received in the triggering space 2134 and connected to the rotating rod 2412, and the push rod 2411 moves along the second direction Y to push the rotating rod 2412 to rotate. At the same time, the sliding groove 2135 can also be used as a limiting component for the movement of the storage cabinet 220, so that the storage cabinet 220 can move smoothly.

[0097] In a specific embodiment, the rotating shaft 2413 is disposed in the middle of the trigger space 2134. In the height direction, the sliding groove 2135 is located above the rotating shaft 2413, and the elastic member 242 is located below the rotating shaft 2413. Alternatively, in the height direction, the sliding groove 2135 is located below the rotating shaft 2413, and the elastic member 242 is located above the rotating shaft 2413. The deformation mode of the elastic member 242 is not limited and can be stretching or compression, and the stretching or compression mode should be determined according to the rotation direction of the rotating rod 2412.

[0098] In a specific embodiment, please refer to Figure 9 and Figure 10 , the magnetic attracting member 231 is disposed on the top wall of the trigger space 2134 and is located at the end in the second direction Y. The cooperating member 232 is disposed at one end of the push rod 2411 away from the left side plate. It can be understood that the push rod 2411 extends into the trigger space 2134 through the sliding groove 2135. During the sliding process of the push rod 2411 along the second direction Y, the storage cabinet 220 is inserted. When the push rod 2411 slides to the deepest part of the trigger space 2134, the cooperating member 232 at the end of the push rod 2411 is attracted by the magnetic attracting member 231 to achieve locking. Moreover, the push rod 2411 keeps pressing the rotating rod 2412 so that the elastic member 242 has elastic potential energy.

[0099] In a specific embodiment, the trigger assembly 241 only includes the push rod 2411, and the push rod 2411 is disposed on the side of the storage cabinet 220; the inner space wall plate 2133 is provided with a trigger space 2134, and the elastic member 242 is received in the trigger space 2134; a sliding groove 2135 is provided on the surface of the inner space wall plate 2133 facing the left side plate, and the sliding groove 2135 is used to communicate the trigger space 2134 and the storage space 211. The sliding groove 2135 extends along the second direction Y, and the push rod 2411 extends into the sliding groove 2135 and is connected to one end of the elastic member 242. In this way, the push rod 2411 can directly press the elastic member 242 until it is compressed, so that the elastic member 242 has elastic potential energy.

[0100] In one implementation manner, please refer to Figures 11 - 14 , the magnetic attracting member 231 includes a first magnetic attracting member 2311 and a second magnetic attracting member 2312, and the cooperating member 232 is a cooperating hole 232A opened on the storage cabinet 220. In the locked state R1, the first magnetic attracting member 2311 and the second magnetic attracting member 2312 are separated, and the second magnetic attracting member 2312 extends into the cooperating hole 232A. In the unlocked state R2, the second magnetic attracting member 2312 is magnetically connected to the first magnetic attracting member 2311, and the second magnetic attracting member 2312 disengages from the cooperating hole 232A.

[0101] In a specific embodiment, please refer to Figure 11 and Figure 12, the loading frame 210 has slide rails 233, the storage cabinet 220 has sliding rods 234, and the sliding rods 234 are slidably connected to the slide rails 233. The slide rails 233 are arranged on the wall plate in the storage space 211, and the slide rails 233 extend along the second direction Y. The number of the slide rails 233 is two, and the two slide rails 233 are relatively spaced along the first direction X. The storage cabinet 220 is located between the two slide rails 233, and the two slide rails 233 are symmetrically arranged.

[0102] In a specific embodiment, please refer to Figure 11 and Figure 12 , the sliding rods 234 are arranged outside the side plates of the storage cabinet 220, and the sliding rods 234 extend along the second direction Y. The number of the sliding rods 234 is two, and the two sliding rods 234 are arranged away from each other along the first direction X. The two sliding rods 234 are in one-to-one correspondence and cooperation with the two sliding rods 234. It can be understood that the two sliding rods 234 are installed on both sides of the storage cabinet 220, and the storage cabinet 220 is inserted or withdrawn along the second direction Y through the two sliding rods 234.

[0103] In a specific embodiment, please refer to Figure 11 and Figure 12 , the structures of the two sliding rods 234 are opposite and symmetrically arranged, so the following descriptions are all about one of the sliding rods 234 and the slide rails 233. Along the height direction of the surgical instrument cart 1000 (hereinafter referred to as the third direction Z), the sliding rod 234 is arranged above the slide rail 233. The above-mentioned mating hole 232A is formed in the sliding rod 234, and the mating hole 232A penetrates the sliding rod 234 along the third direction Z. A limiting hole 2331 is formed in the slide rail 233, and the limiting hole 2331 penetrates the slide rail 233 along the third direction Z, and the limiting hole 2331 extends along the second direction Y on the slide rail 233.

[0104] In a specific embodiment, please refer to Figure 13 and Figure 14 , along the third direction Z, the first magnetic member 2311 is arranged above the second magnetic member 2312, and the second magnetic member 2312 is arranged above the sliding rod 234. The first magnetic member 2311 can be an electromagnet, and the second magnetic member 2312 can be made of iron or another piece of opposite-sex magnet. The first magnetic member 2311 is fixedly arranged, and the second magnetic member 2312 is slidable along the third direction Z. That is, the second magnetic member 2312 is slidably connected to the loading frame 210.

[0105] In a specific embodiment, please refer to Figure 13 and Figure 14During the process of inserting the storage cabinet 220 into the storage space 211 along the second direction Y, the first magnetic member 2311 does not generate magnetic attraction, and the second magnetic member 2312 can fall naturally under the action of gravity. The sliding rod 234 moves to squeeze the second magnetic member 2312 and abuts against the second magnetic member 2312 to move upward (in the third direction Z). The sliding rod 234 remains passing through the second magnetic member 2312 until when the mating hole 232A passes through the second magnetic member 2312, the second magnetic member 2312 is inserted into the mating hole 232A, thereby reaching the locked state R1. Then, when it is necessary to switch to the unlocked state R2, the first magnetic member 2311 generates magnetic attraction, the second magnetic member 2312 moves upward and disengages from the mating hole 232A, and the storage cabinet 220 resumes the movable state.

[0106] In a specific embodiment, please refer to Figure 13 and Figure 14 , the end of the sliding rod 234 has a first inclined surface T1, and the second magnetic member 2312 has a second inclined surface T2. The first inclined surface T1 and the second inclined surface T2 face each other and are parallel. When the sliding rod 234 moves to squeeze the second magnetic member 2312, the first inclined surface T1 and the second inclined surface T2 abut against each other, and the sliding rod 234 uses the cooperation of the two inclined surfaces to squeeze the second magnetic member 2312 to move. Preferably, after the second magnetic member 2312 passes through the mating hole 232A, at least a part of it extends into the limiting hole 2331.

[0107] In a specific embodiment, the cooperation mode of the first magnetic member 2311, the second magnetic member 2312 and the mating hole 232A can reduce the utilization of the first magnetic member 2311, that is, contrary to the above embodiment, the first magnetic member 2311 generates magnetic force only during the unlocking process, and there is no need for the first magnetic member 2311 to always maintain magnetic force. At the same time, the second magnetic member 2312 uses the action of gravity to penetrate into the mating hole 232A to achieve locking, which can not only save kinetic energy, but also has a greater vertical force and a more secure locking. In addition, the present invention also sets the cooperation of the first inclined surface T1 and the second inclined surface T2 so that the sliding rod 234 can smoothly squeeze the second magnetic member 2312, and the sliding rod 234 moves toward the second inclined surface T2, so that the second inclined surface T2 provides a greater resistance effect after locking.

[0108] In a specific embodiment, please refer to Figure 13 and Figure 14, the triggering component 241 is a bump 241A. The bump 241A is connected to the sliding rod 234 and extends into the limiting hole 2331. The elastic member 242 is installed in the limiting hole 2331 and extends along the second direction Y. It can be understood that the ejection mechanism is integrated on the sliding rod 234 and the slide rail 233. During the movement of the sliding rod 234, the bump 241A moves towards the elastic member 242 along the extending direction of the limiting hole 2331 until the bump 241A abuts against the elastic member 242, and the bump 241A drives the elastic member 242 to undergo elastic deformation.

[0109] In a specific embodiment, please refer to Figure 13 and Figure 14 , after the second magnetic attracting member 2312 extends into the mating hole 232A, the bump 241A squeezes the elastic member 242 to elastically deform. However, under the cooperation restriction of the second magnetic attracting member 2312 and the mating hole 232A, the elastic member 242 cannot recover. After the second magnetic attracting member 2312 disengages from the mating hole 232A, the elastic member 242 recovers under the action of elastic potential energy and reversely drives the bump 241A to drive the storage cabinet 220 to slide horizontally. Further, when the surgical instrument cart 1000 runs out of power, the second magnetic attracting member 2312 ensures that the storage cabinet 220 will not pop out under the action of gravity, which is more reliable in the power-off state compared to the above embodiment.

[0110] In one implementation manner, the loading structure 200 further includes a second driving member. The second driving member is installed in the loading frame 210. The second driving member is a motor, and the second driving member is used to drive the storage cabinet 220 to move along the second direction Y. Specifically, after the triggering component 241 ejects the storage cabinet 220, due to the limitation of the elastic member 242, the storage cabinet 220 will not be fully opened. Therefore, in order to improve the degree of automation, a driving member can be set to drive the storage cabinet 220 to move along the second direction Y until it is fully pulled out.

[0111] In a specific embodiment, when the storage cabinet 220 needs to be closed, the second driving member can also drive the storage cabinet 220 to move along the second direction Y until it is fully inserted, and the second driving member transfers the kinetic energy to the elastic member 242 to be converted into elastic potential energy. The second driving member can be electrically connected to the controller 140, and the controller 140 controls the start and stop of the second driving member. The advantage of setting the second driving member is to improve the degree of automation and avoid direct contact between medical staff and the storage cabinet 220; and the cooperation between the triggering component 241 and the second driving member can achieve the effect of energy conversion and storage.

[0112] In one implementation manner, please refer to Figure 15, the loading frame 210 further includes a top surface 210S facing away from the chassis structure 100. A mating groove 250 is defined in the top surface 210S. The contour dimensions of the mating groove 250 are adapted to the medical tray. The mating groove 250 is configured to receive the medical tray, and the depth of the mating groove 250 is less than the height of the medical tray.

[0113] In a specific embodiment, during the surgical procedure, to ensure the orderly placement and convenient access of surgical instruments, the surgical instruments are placed in a medical tray. Therefore, the medical tray, together with the surgical instruments, needs to be directly placed on the top surface 210S of the loading frame 210 after being taken out of the storage cabinet 220. The mating groove 250 defined in the top surface 210S can be used to fix the medical tray, and the depth of the mating groove 250 is relatively small, so that the medical tray protrudes from the mating groove 250, facilitating access.

[0114] In a specific embodiment, please refer to Figure 15 , a plurality of elastic pieces 251 are provided on the side wall of the mating groove 250. The elastic pieces 251 are elastic and protrude from the side wall of the mating groove 250. Thus, after the medical tray is placed in the mating groove 250, the medical tray presses the elastic pieces 251 to deform, and the elastic pieces 251 can also fix the medical tray thereby. This can avoid the scattering of surgical instruments caused by the impact on the surgical instrument cart 1000 due to the movement of personnel during the surgical procedure.

[0115] In one embodiment, please refer to Figure 15 , the top view projection of the top surface 210S is rectangular. The loading structure 200 further includes two armrests 260. The armrests 260 are connected to the loading frame 210. The two armrests 260 are disposed at opposite ends of the top surface 210S, and the mating groove 250 is located between the two armrests 260; fixing portions 270 are further provided at the four corners of the top surface 210S. The fixing portions 270 are configured to fix the sterile cloth laid on the surgical instrument cart 1000.

[0116] In a specific embodiment, please refer to Figure 15 , the fixing portion 270 includes a positioning hole and a positioning pin. The positioning pin is insertable and removable into the positioning hole, and the positioning hole is defined in the top surface 210S. When it is necessary to lay the sterile cloth, the positioning pin is pulled out, then the sterile cloth is laid, and then the positioning pin is inserted through the sterile cloth into the positioning hole to complete the fixation of the sterile cloth.

[0117] In one embodiment, please refer to Figure 15 , the loading structure 200 further includes a protective cover 280. One side of the protective cover 280 has an opening. A lifting handle and a sterilization label slot are provided at the top of the protective cover 280. The protective cover 280 is configured to cover the outer periphery of the medical tray placed in the mating groove 250.

[0118] In a specific embodiment, after the operation is completed, the nurse can directly cover the protective cover 280 around the medical tray, thereby preventing cross-infection between the surgical instruments inside and the external environment. The protective cover 280 and the top surface 210S of the loading frame 210 can be magnetically coupled. That is, magnets are provided on the open-side end surface of the protective cover 280, and corresponding fixed magnets are provided on the top surface 210S of the loading frame 210, so that the protective cover 280 and the loading frame 210 are fixedly coupled.

[0119] In one embodiment, the loading structure 200 further includes an ultraviolet irradiation disinfection system and a heating and constant temperature disinfection system. The ultraviolet irradiation disinfection system is used to provide ultraviolet light to the storage cabinet, and the heating and constant temperature disinfection system is used to heat the storage cabinet and maintain a constant temperature. Specifically, the ultraviolet irradiation disinfection system and the heating and constant temperature disinfection system are provided inside the loading structure 200 and can disinfect the storage cabinet.

[0120] In a specific embodiment, the ultraviolet irradiation disinfection system includes an ultraviolet lamp, which is provided at the top of the storage space 211. By setting up the ultraviolet disinfection system, the environment inside the storage cabinet 220 can be greatly improved, and the growth of bacteria can be avoided. The heating and constant temperature disinfection system includes a heater and an exhaust fan. The heater and the exhaust fan are provided in the loading frame 210. The exhaust fan sends air into the storage cabinet 220, and the heater can be located on the air outlet channel of the exhaust fan.

[0121]

Control Method of Surgical Instrument Cart

[0122] Step S200, the chassis structure carries the loading structure to reach the target position, the storage cabinet switches from the locked state to the unlocked state, and the storage cabinet is released from the storage space.

[0123] In a specific embodiment, the chassis structure obtains surgical information, where the surgical information includes the target position and the surgical time. Among them, the target position is the operating room where the operation is to be performed, and the surgical time is the specific time point when the operation starts. It can be understood that the chassis structure needs to first obtain the target position and arrive at the target position before the operation starts. Optionally, specifically, the interaction unit in the chassis structure obtains the surgical information.

[0124] In a specific embodiment, the controller formulates a preset path and activates the power system. The specified preset path can be a movement path stored in the storage unit or a movement path planned according to the environment. The controller formulates data of the preset path and controls the power system to travel to the target position along the preset path.

[0125] In a specific embodiment, when the surgical instrument cart is in the starting position, the storage cabinet can be in an unlocked state, so as to facilitate placing surgical instruments into the storage cabinet. After the surgical instrument cart receives surgical information and completes the storage of surgical instruments, the storage cabinet switches from the unlocked state to the locked state and remains in the locked state throughout the travel along the preset path.

[0126] In one implementation, during the movement of the chassis structure from the starting position to the target position along the preset path, it will encounter the operating room door. In the prior art, in order to maintain the environmental conditions in the operating room, the operating room door is always in a closed state and needs to be manually opened. The movement of the surgical instrument cart requires the cooperation of the opening and closing of the operating room door.

[0127] In a specific embodiment, the operating room doors in the prior art include a mechanical door and a manual door. Among them, the mechanical door is controlled by electro-mechanics and can be automatically opened by control, but the manual door needs to be manually pushed open by a person. Therefore, for the situation of encountering the operating room door during the movement, the following specific steps are included: Step S110, when the chassis structure moves to in front of the operating room door, the chassis structure sends an opening signal to the operating room door and waits for the first reply signal.

[0128] Step S120, within the preset time, if the chassis structure does not receive the first reply signal, the chassis structure emits a reminder signal and waits for the second reply signal.

[0129] Step S130, within the preset time, if the chassis structure receives the first reply signal; or, if the chassis structure receives the second reply signal, the chassis structure moves and passes through the operating room door.

[0130] In a specific embodiment, the chassis structure moves along the preset path. After moving to in front of the operating room door, the interaction unit (such as an infrared sensor, etc.) detects an obstacle ahead. After determining that the obstacle is the operating room door, the chassis structure sends an opening signal to the operating room door and waits for the first reply signal.

[0131] In a specific embodiment, the first reply signal is sent by the interaction unit. The first reply signal can be a signal indicating no obstacle detected by the interaction unit. It can be understood that after the operating room door is opened, there is no obstacle in front of the surgical instrument cart and it can continue to move forward. Or, the first reply signal is sent by the operating room door. The operating room door is a mechanical door and sends a signal to the chassis structure immediately after it is opened.

[0132] In a specific embodiment, during a preset time, the situation where the chassis structure does not receive the first reply signal may correspond to the operating room door needing to be manually pushed open by a person or the operating room door malfunctioning. Therefore, the chassis structure cannot receive the signal that the operating room door has been opened. The chassis structure continues to emit a reminder signal, which is used to remind the surrounding personnel to assist in opening the door and waits for the first reply signal. The surrounding personnel can be doctors, nurses, etc.

[0133] In a specific embodiment, the second reply signal is sent by the interaction unit, and the second reply signal can be a signal without obstacles detected by the interaction unit. It can be understood that after the operating room door is opened, there are no obstacles in front of the surgical instrument cart and it can continue to move forward. Or, the second reply signal is sent by the surrounding personnel, and the surrounding personnel send a signal that it can continue to move forward through the interaction unit (such as a touch screen).

[0134] In a specific embodiment, the preset time can be 5s to 10s, specifically 5s, 6s, 7s, 8s, 9s, 10s. The reminder signal includes an indicator light, a prompt sound, etc. Specifically, it can be indicator lights of yellow, red, and blue, and can also be a continuously emitted voice prompt or a short sound prompt.

[0135] In one implementation, the surgical instrument cart can arrive at the operating room prior to the medical staff. In order to ensure the hygienic safety of the surgical instruments, the change of the storage cabinet from the locked state to the unlocked state can be switched according to the needs of the medical staff. Specifically, it includes the following steps: Step S210, the chassis structure carries the loading structure to the target position, and the loading structure remains in a standby state.

[0136] Step S220, the loading structure obtains an opening signal, the storage cabinet is switched from the locked state to the unlocked state, and the storage cabinet is released from the storage space.

[0137] In a specific embodiment, when the loading structure arrives at the target position (operating room), the loading structure does not immediately switch the storage cabinet from the locked state to the unlocked state, but keeps the storage cabinet in the locked state, and the loading structure remains in standby, waiting for the command signal to open the storage cabinet.

[0138] In a specific embodiment, the opening signal is sent by the medical staff through the interaction unit. The medical staff sends an opening signal for unlocking the storage cabinet through the interaction unit (such as a touch screen). The storage cabinet is switched from the locked state to the unlocked state, and the storage cabinet is released from the storage space.

[0139] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0140] The above-disclosed is only a preferred embodiment of the present application, and of course, it cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
