Description

Technical Field

[0001] The present invention belongs to the research field of storage technology, and particularly relates to a multifunctional laparoscopic surgical instrument storage device. Background Art

[0002] Laparoscopic surgery refers to a surgery completed using modern high-tech medical technology. It is to operate surgical instruments outside the abdomen under the monitoring and guidance of a high-tech display screen through a laparoscope in a closed abdominal cavity to complete operations such as exploration, electrocoagulation, hemostasis, tissue separation and incision, and suture of diseased tissues. The surgical instruments used in laparoscopic surgery include an electric hook, a dissecting forceps, a grasping forceps, an intestinal forceps, a suction tube, a puncture needle, a needle holder, intraoperative cholangiography, a stapler, a closure device, etc.; due to the variety of instruments used in laparoscopic surgery, there is an urgent need to design a device that is convenient for storing the instruments used in laparoscopic surgery.

[0003] A patent with the publication number CN113509275B discloses a multifunctional laparoscopic surgical instrument storage device, which includes: a box body for placing surgical instruments, the box body includes a placement table for placing laparoscopic surgical instruments and a circuit storage table for storing the wires of surgical instruments; the placement table and the circuit storage table are both located on the same horizontal plane of the box body, and the placement table and the circuit storage table are detachably connected; a disinfection mechanism for disinfecting and cleaning laparoscopic surgical instruments is provided on the placement table; a reel mechanism for winding the wires is provided in the circuit storage table, and the reel mechanism adjusts the release length of the wires according to the movement range of the surgical instruments; when in use, the laparoscopic surgical instruments are placed on the placement table, and the disinfection mechanism is used to disinfect and clean the laparoscopic surgical instruments; the reel mechanism is used to store the wires connected to the laparoscopic surgical instruments; to prevent them from being placed in a mess and affecting the use by doctors.

[0004] The placement table provided by the above technical solution can only store surgical instruments with wires. If it is necessary to store surgical instruments without wires such as a puncture needle and a needle holder, it will occupy the storage position of surgical instruments with wires, and all the surgical instruments used in laparoscopic surgery cannot be stored, resulting in poor storage effect.

[0005] In addition, the above technical solution does not provide a space for storing the electrocoagulation hook. During the operation, the end of the electrocoagulation hook has a high temperature after use. Therefore, in the above solution, the electrocoagulation hook needs to be naturally cooled before being placed in the box for storage. If a medical staff accidentally touches it during the cooling process, it will damage the medical staff, posing a safety hazard. Summary of the Invention

[0006] The object of the present invention is to overcome the problems of poor storage effect and safety hazards existing in the existing multifunctional laparoscopic surgical instrument storage device.

The first storage bag can store surgical instruments such as scalpels and surgical forceps, and surgical instruments with wires can also be placed in the second-layer drawer to achieve the storage of all surgical instruments used in laparoscopic surgery. A linkage opening mechanism is also provided in the double-layer storage box. After the linkage opening mechanism is activated, it can turn up the lid of the double-layer storage box, open the second-layer drawer, and turn the first storage bag upwards to a vertical state to facilitate medical staff to take surgical instruments. Among them, an electrocoagulation hook hanging mechanism is also provided on the first-layer placement tray. The electrocoagulation hook hanging mechanism can be used to hang the used electrocoagulation hook so that the high-temperature end of the electrocoagulation hook can naturally cool, thereby preventing the high temperature of the used electrocoagulation hook from scalding medical staff, reducing potential safety hazards, and ensuring the smooth progress of the operation.

[0041] Beneficial effects:

[0042] 1. Through the combined design of the double-layer storage box, the linkage opening structure and the electrocoagulation hook suspension mechanism in the present invention, medical staff only need to turn on the switch to open the box cover, the second-layer drawer, and flip the first-layer storage bag. That is, in actual use, the linkage opening structure and the electrocoagulation hook suspension mechanism are opened simultaneously. The first electric push rod in the linkage opening structure flips the box cover of the double-layer storage box, so that when the first-layer placement tray is opened, the first sliding block in the linkage opening structure moves. The first sliding block gradually switches the first storage bag from a horizontal state to a vertical state through the first storage bag flipping component, and the first sliding block opens the second-layer drawer through the second drawer opening component. Medical staff can take surgical instruments such as scalpels and surgical forceps in the first-layer storage bag, and surgical instruments with wires in the second-layer drawer. That is, the first storage bag and the second-layer drawer in the double-layer storage box can store all the surgical instruments used in laparoscopic surgery;

[0043] And when the first electric push rod flips the box cover of the double-layer storage box, so that the first-layer placement tray is opened, the hanger in the electrocoagulation hook suspension mechanism gradually moves towards the outer edge of the double-layer storage box driven by the second sliding block. The third motor in the hanger drives the suspension plate to switch from a horizontal state to an inclined state, and the rotating rod rotates upward, so that the suspension plate rises, so as to place the used electrocoagulation hook on the suspension plate, so that the high-temperature end of the electrocoagulation hook cools naturally. And after use, only need to turn off the switch to close the opening structure and the electrocoagulation hook suspension mechanism at the same time to realize the storage of the electrocoagulation hook, and the operation is simple and convenient.

[0044] Second, through the combined design of the third motor, the rotating rod and the hanger, the hanging plate in the hanger can be raised and tilted, so that medical staff can place the electrocoagulation hook on the hanging plate. Among them, the hanging plate is provided with a fixed clip for clamping the hand-held end of the electrocoagulation hook and a placing block for placing the electrocoagulation hook, which can realize the storage of the electrocoagulation hook and ensure the natural cooling of the electrocoagulation hook to avoid accidental scalding of medical staff.

[0045] Third, the combined design of the torsion spring, the connecting rope, the rotating rod and the rotating gear provided by the embodiment of the present invention can release the connecting rope wound on the connecting rod of the rotating gear while the rotating gear rotates, so that the hanging plate tilts quickly.

[0046] Fourth, through the combined design of the hand-held strip and the limiting strip, while the medical staff holds the double-layer storage box by hand, the limiting strip can limit the surgical instruments located in the second-layer drawer groove to prevent the surgical instruments from falling out of the groove.

[0047] Fifth, the inside of the second-layer drawer provided by the embodiment of the present invention is also provided with a wire winding mechanism, which can wind and store the wires of surgical instruments to avoid the situation where the wires between different surgical instruments are wound around each other and cannot be distinguished.

[0079] Embodiment 1

[0080] This embodiment provides a multifunctional laparoscopic surgical instrument storage device, as Figure 1-16As shown in the figure, it includes a double-layer storage box 1, and a first storage bag 2, a second storage bag 5, a linkage opening mechanism 3 and an electrocoagulation hook suspension mechanism 4 arranged in the double-layer storage box 1.

[0081] As Figure 1 shown, the double-layer storage box 1 includes a first-layer placement tray 11 and a second-layer drawer 12;

[0082] Above the first-layer placement tray 11, there is a box cover 13 rotatably connected to the first-layer placement tray 11.

[0083] Inside the second-layer drawer 12, there are multiple grooves 12a for placing surgical instruments with wires, and on the two opposite inner surfaces of the groove 12a, there are limiting grooves perpendicular and communicating with the groove 12a respectively; the limiting strip 12b is located in the limiting groove. After placing the surgical instrument in the groove 12a, when the medical staff holds the double-layer storage box 1 by hand, the limiting strip 12b freely falls from the limiting groove to the inner wall surface of the groove 12b on the opposite side, so as to limit the surgical instrument in the groove 12a to prevent the surgical instrument from scattering.

[0084] Among them, the limiting strip 12b is of a long strip structure, and the length of the limiting strip 12b is greater than the width of the groove 12a.

[0085] The first storage bag 2 is located on the first-layer placement tray 11, and the bottom end of the first storage bag 2 is rotatably connected to the inner wall of the double-layer storage box 1 through a rotating rod. Specifically, the first storage bag 2 includes a backboard and a storage cloth bag arranged on the backboard; in actual use, the lower end of the backboard in the first storage bag 2 is rotatably connected to the inner wall of the double-layer storage box 1 through a rotating rod, and the backboard in the first storage bag 2 is rotatably connected to the linkage opening mechanism 3.

[0086] As Figure 2-8 shown, the linkage opening mechanism 3 includes two box cover flipping components 31, two second-layer drawer flipping components 32 and a first storage bag flipping component 33; among them, the two second-layer drawer flipping components 32 are respectively arranged at both ends of the linkage opening mechanism 3 and are respectively rotatably connected to the linkage opening mechanism 3; the first storage bag flipping component 33 is fixedly connected to the linkage opening mechanism 31.

[0087] The structures of the two box cover flipping components 31 are the same. As Figure 4 and 8 shown, each box cover flipping component 31 includes a first fixed block 31a, a first electric push rod 31b, a threaded rod 31c, a first sliding block 31d and a first motor 31e. Among them, the first electric push rod 31b and the first motor 31e are both connected to a switch 14 arranged on the box cover 13, that is, the first electric push rod 31b and the first motor 31e are started synchronously.

[0088] The first fixing block 31a is fixedly arranged on the inner surface of the lid 13 of the double-layer storage box 1.

[0089] The first sliding block 31d has a square structure, and a threaded through-hole is provided at its center; the first sliding block 31d is sleeved on the threaded rod 31c through this threaded through-hole.

[0090] The threaded rod 31c is connected to the output end of the first motor 31e.

[0091] The end of the push rod part of the first electric push rod 31b is rotatably connected to the first fixing block 31a, and the end of the fixed tube part of the first electric push rod 31b is rotatably connected to the upper end of the first sliding block 31d.

[0092] Among them, as Figure 7 shown, the first sliding block 31d is also sleeved on the guide rod 9, and both ends of the guide rod 9 are fixedly connected to the inner wall of the double-layer storage box 1. In this way, during the movement of the first sliding block 31d, it will not rotate along with the threaded rod 31c.

[0093] In practical applications, in the closed state of the double-layer storage box 1, the initial position of the first sliding block 31d is at one end of the threaded rod 31c close to the lid 13. After the medical staff activates the linkage opening mechanism 3, the push rod part of the first electric push rod 31b extends, causing the lid 13 to flip upward and the first layer placement tray 11 to be opened; at the same time, the first motor 31e starts, and the first motor 31e drives the threaded rod 31c to rotate, thereby causing the first sliding block 31d threadedly connected to the threaded rod 31c to move towards the end away from the lid 13. In this way, the first sliding block 31d drives the second-layer drawer 12 to be opened through the second-layer drawer opening assembly 32 connected thereto, and drives the first storage bag 2 to flip upward through the first storage bag flipping assembly 33 connected thereto, so that the medical staff can take surgical instruments. Among them, during the movement of the first sliding block 31d towards the end away from the lid 13, the fixed tube part of the first electric push rod 31b moves synchronously, and at the same time, the push rod part of the first electric push rod 31b extends outward, keeping the lid 13 in the open state.

[0094] As Figure 8 shown, the structures of the two second-layer drawer opening assemblies 32 are the same. Each second-layer drawer opening assembly 2 includes a strip-shaped hole 21a, a second fixing block 32b and a linkage rod 32c arranged on the first layer placement tray 11;

[0095] Among them, the second fixing block 32b is fixedly arranged on the inner bottom surface of the second-layer drawer 12;

[0096] One end of the linkage rod 32c passes through the strip-shaped hole 21a and is rotatably connected to the side surface of the first sliding block 31d, and the other end is rotatably connected to the second fixing block 32b;

[0097] In this way, during the process of the first sliding block 31d moving towards the end away from the box cover 13, the first sliding block 31d drives the second fixed block 32b to move in the same direction through the linkage rod 32c, and further the second - layer drawer 12 fixedly connected to the second fixed block 32b moves in the same direction. At this time, the second - layer drawer 12 is opened.

[0098] The first storage bag flipping assembly 33 includes a cross - bar 33a and two longitudinal bars 33b connected to the cross - bar 33a, wherein the two longitudinal bars 33b are arranged in parallel with each other.

[0099] Specifically, both ends of the cross - bar 33a are fixedly connected to the sides of the first sliding blocks 31d in the two groups of box - cover flipping assemblies 31. It should be noted that the embodiment of the present invention does not limit the fixed - connection method between the cross - bar 33a and the first sliding block 31d. By way of example, the cross - bar 33a is integrally connected to the first sliding block 31d.

[0100] The lower end of each longitudinal bar 33b is rotatably connected to the cross - bar 33a, and its upper end is rotatably connected to the back plate in the first storage bag 2.

[0101] In this way, during the process of the first sliding block 31d moving towards the end away from the box cover 13, the cross - bar 33a moves in the same direction as the first sliding block 31d, and further the upper end of the longitudinal bar 33b flips upwards, so that the longitudinal bar 33b, the first storage bag 2 and the first - layer placement tray 11 form a triangular support, realizing the upward flipping of the first storage bag 2, so as to facilitate medical staff to take the medical instruments placed in the storage cloth bag of the first storage bag 2.

[0102] As Figure 9-14 shown, the electro - coagulation hook suspension mechanism 4 includes a bidirectional threaded rod 41 and a hanger sleeved on the bidirectional threaded rod 41;

[0103] Specifically, the bidirectional threaded rod 41 is connected to the output end of the second motor 42.

[0104] In practical applications, the first electric push rod 31b, the first motor 31e and the second motor 42 are turned on simultaneously. In this way, while the first motor 31e drives the first sliding block 31d to move through the threaded rod 31c and drives the first storage bag 2 to flip upwards, the second motor 42 drives the two hangers arranged on the bidirectional threaded rod 41 to move towards the opposite sides.

[0105] The structures of the above - mentioned two hangers are the same, and each hanger includes a second sliding block 43, a rotating rod 44 and a hanging plate 45.

[0106] The second sliding block 43 has a square structure with a threaded through-hole centered thereon. When in use, the second sliding block 46 is sleeved on the bidirectional threaded rod 44; and the second sliding block 43 is further provided with a through-hole. Similar to the first sliding block 31d, the second sliding block 43 is also sleeved on the guide rod 9, and both ends of the guide rod 9 are fixedly connected to the inner wall of the double-layer storage box 1. In this way, during the movement of the second sliding block 43, the second sliding block 43 will not rotate along with the bidirectional threaded rod 41.

[0107] Specifically, a rotating gear 43a, a connecting rope 43b, and a third motor embedded in the second sliding block 43 are provided on the side surface of the second sliding block 43; wherein, one end of the rotating gear 43a is connected to the output end of the third motor, and a connecting rod for connecting with the connecting rope 43b is provided at the end of the rotating gear 43a away from the third motor. When in use, one end of the connecting rope 43b is connected to the hanging plate 45, and the other end is wound around the connecting rod on the side surface of the rotating gear 43a and is connected to the connecting rod on the side surface of the rotating gear 43a.

[0108] The rotating rod 27 has a sheet-like structure with a threaded hole provided at the lower end. One end of the rotating rod 27 is provided with a connecting hole, and a gear track is provided on the inner wall of the connecting hole. The rotating rod 27 is meshed and connected with the rotating gear 43a through the gear track, and its upper end is connected to the hanging plate 45 through a torsion spring;

[0109] One end of the connecting rope 43b is fixedly connected to the connecting rod provided on the rotating gear 43a, and the other end is fixedly connected to the hanging plate 45.

[0110] In this way, the two second sliding blocks 43 are respectively located on the opposite threaded portions of the bidirectional threaded rod 41. In this way, when the bidirectional threaded rod 41 rotates, the two second sliding blocks 43 move in opposite directions.

[0111] When the double-layer storage box is closed, the two second sliding blocks 4 are located at the center of the bidirectional threaded rod 41, the connecting rope 43b is wound around the connecting rod provided on the rotating gear 43a, and the hanging plate 45 is in a horizontal state under the pulling force of the connecting rope 43b;

[0112] When the second motor 42 is started, the third motor is also started simultaneously. That is, while the second motor 42 drives the two second sliding blocks 43 to move towards the edges of the double-layer storage box 1 respectively, the third motor embedded in the second sliding block 46 drives the rotating gear 43a to rotate. Furthermore, the rotating gear 43a drives the rotating rod 44 to rotate, so that while the upper end of the rotating rod 44 is lifted upward, the connecting rope 43b wound around the connecting rod of the rotating gear 43a is released. At this time, the torsion spring for connecting the hanging plate 45 and the rotating rod 44 returns to its natural state, making the hanging plate 45 in an inclined state so that medical staff can place the electrocoagulation hook on the hanging plate 45.

[0113] The hanging plate 45 is in a plate-like structure, and a fixing clip 45a and two placing blocks 45b located on the side of the fixing clip 45a are provided on the surface of the hanging plate 45; among them, a pressure sensor 45c is provided on the placing block 45b close to the fixing clip 45a. The pressure sensor 45c is electrically connected to a second electric push rod provided on the hanging plate 45.

[0114] In this way, after the medical staff place the electrocoagulation hook on the placing block 45b, when the pressure sensor 45c is subjected to the pressure of the electrocoagulation hook, the second electric push rod connected to the fixing clip 45a is turned on, so that the second electric push rod extends, and the clamping end of the fixing clip 45a is opened. Then, the second electric push rod is turned off, and the push rod part of the second electric push rod retracts to the initial position. At this time, the second electric push rod clamps the fixed end of the electrocoagulation hook to prevent the electrocoagulation hook from falling until the operating end of the electrocoagulation hook naturally cools to room temperature for storage.

[0115] Specifically, the fixing clip 43a includes two rotation link rods with the same structure and symmetrically arranged up and down;

[0116] As Figure 7 shown, each rotation link rod includes a straight rod 43a-1 and a "V"-shaped rod 43a-2; in practical applications, one end of the straight rod 43a-1 is rotatably connected to the fixed pipe part of the second electric push rod, and the other end is rotatably connected to the "V"-shaped rod 48a-2;

[0117] A rack for increasing the surface friction of the electrocoagulation hook is provided at one end of the "V"-shaped rod 43a-2 away from the straight rod 43a-1, and the central rotation angle of the "V"-shaped rod 43a-2 is rotatably connected to the end of the push rod part of the second electric push rod.

[0118] In this way, during the process of the push rod part of the second electric push rod extending, the included angle between the straight rod 48a-1 and the "V"-shaped rod 48a-2 becomes larger. At this time, the racks on the two "V"-shaped rods 48a-2 move away from each other, so that the end of the electrocoagulation hook is located between the two racks. Then, the push rod part of the second electric push rod retracts. At this time, the included angle between the "V"-shaped rods 43a-2 becomes smaller, and the racks on the two "V"-shaped rods 43a-2 move closer to each other, thereby realizing the clamping and fixing of the end of the electrocoagulation hook.

[0119] It should be noted that in the embodiment of the present invention, the first motor 31e, the second motor 42, the third motor, and the first electric push rod 31b are all electrically connected to the switch 14.

[0120] Embodiment 2

[0121] Based on Embodiment 1, the difference from Embodiment 1 is that as Figure 1 and 8As shown in the figure, a second storage bag 5 is further provided on the inner surface of the lid 13 provided by the embodiment of the present invention, and a third electric push rod 6 connected to the second storage bag 5.

[0122] The structure of the second storage bag 5 is the same as that of the first storage bag 2, and both include a back plate and a storage cloth bag provided on the back plate. In practical applications, the lower end of the back plate in the second storage bag 5 is rotatably connected to the first fixing block 31a through a rotating rod.

[0123] The third electric push rod 6 is fixedly provided on the inner surface of the lid 13, and the second electric push rod 6 is located at the upper end of the second storage bag 5;

[0124] Specifically, a spherical groove is provided at the end of the push rod part of the third electric push rod 6, and a rotating ball 61 is provided in the spherical groove. Among them, the rotating ball 61 is fixedly connected to the second storage bag 5. In this way, while the push rod part of the second electric push rod 6 extends, the rotating ball 61 can adjust the inclination angle of the second storage bag 5, so as to ensure the normal extension of the push rod part of the third electric push rod 6.

[0125] In this way, while the first motor 31e and the third motor 49 are started, the third electric push rod 6 is started at the same time, so that the upper end of the second storage bag 5 is inclined, so that medical staff can take the surgical instruments located in the second storage bag 5.

[0126] It should be noted that the first motor 31e, the second motor 42, the third motor, the first electric push rod 31b and the third electric push rod 6 provided by the embodiment of the present invention are all electrically connected to the switch 14.

[0127] Embodiment 3

[0128] Based on Embodiment 1, what is different from both Embodiment 1 and Embodiment 2 is that, as Figure 15 shown, a winding limit mechanism 8 is further provided inside the second-layer drawer 12 provided by the embodiment of the present invention.

[0129] Specifically, the winding mechanism 8 includes a fourth motor 82 and a winding rod 81 provided on the output end of the fourth motor 82.

[0130] A plurality of buckles for fixing the wires of surgical instruments are provided on the winding rod 81. Among them, the number of buckles is the same as the number of grooves 12a, and the buckles are located at the ends of the grooves 12a, and the buckles correspond to the grooves 12a one by one. Implementation case:

[0131] Step 1: The medical staff turns on the switch 14. At this time, the first motor 31e, the second motor 42, the third motor, the first electric push rod 31b and the third electric push rod 6 are started simultaneously;

[0132] The push rod part of the first electric push rod 31b extends, and the box cover 13 flips upward under the action of the push rod part of the electric push rod 31b. At this time, the first layer placement tray 11 is opened;

[0133] The first motor 31e drives the first sliding block 31a to move towards the end away from the box cover 13. The first sliding block 31a drives the second layer drawer 12 to be opened through the linkage rod 32c. At the same time, the first sliding block 31a drives the cross bar 33a to gradually move towards the end away from the box cover 13, so that the first storage bag 2 flips upward. At this time, the vertical rod 33b connected to the cross bar 33a, the first storage bag 2, and the first layer placement tray 11 form a triangular support, so that the first storage bag 2 maintains an inclined state for medical staff to take the medical devices in the first storage bag 2;

[0134] The third motor drives the rotating gear 43a to rotate, so that the rotating gear 43a drives the rotating rod 44 to rotate upward, raising the suspension plate 45; at the same time, the connecting rod provided at the end of the rotating gear 43a rotates synchronously with the rotating gear 43a to release the connecting rope 43b wound around the connecting rod of the rotating gear 43a, so that the torsion spring for connecting the suspension plate 45 and the rotating rod 44 returns to its natural state, further enabling the suspension plate 45 to quickly switch from the horizontal state to the inclined state;

[0135] The second motor 42 drives the bidirectional threaded rod 41 to rotate, so that the two second sliding blocks 43 sleeved on the two opposite threaded parts of the bidirectional threaded rod 41 move in opposite directions at the same time until the suspension plate 45 is located on the side of the double-layer storage box 1 for medical staff to hang and place the electrocoagulation hook on the suspension plate 45;

[0136] The push rod part of the third electric push rod 6 extends, so that the second storage bag 5 is in a vertical state for medical staff to take the surgical instruments located in the second storage bag 5;

[0137] Step 2: The medical staff places the used electrocoagulation hook on the placement block 45b of the suspension plate 45, and places the high-temperature end of the electrocoagulation hook on the side away from the fixed clip 45a; after the pressure sensor 45c provided on the placement block 45b is subjected to the pressure of the electrocoagulation hook, the second electric push rod connected to the fixed clip 45a is opened, so that the second electric push rod extends;

[0138] During the process of the push rod part of the second electric push rod extending, the angle between the straight rod and the "V"-shaped rod in the fixed clamp 45a becomes larger, and the racks at the ends of the two "V"-shaped rods move away from each other, causing the opening formed by the racks to become larger, so that the end of the electrocoagulation hook far from the high-temperature operation end is located within the opening. Then, the second electric push rod is closed, causing the push rod part of the second electric push rod to retract. At this time, the angle between the straight rod and the "V"-shaped rod in the fixed clamp 45a becomes smaller, and the racks at the ends of the two "V"-shaped rods move closer to each other, causing the opening formed by the racks to become smaller, thereby realizing the clamping and fixing of the electrocoagulation hook, so that the high-temperature end of the electrocoagulation hook can naturally cool for storage.

[0139] Step 3: Turn on the fourth motor 81 in the wire winding mechanism 8. The fourth motor 81 drives the wire winding rod 82 to rotate, so that the wire wound around the wire winding rod 820 is released, facilitating the medical staff to take out the surgical instrument.

[0140] After use, after the medical staff place the medical instrument in the groove 12a, they start the fourth motor 81, causing the wire of the medical instrument to wind around the wire winding rod 82 therein, realizing the storage of the medical device.

[0141] Furthermore, the medical staff press the switch 14 again, and the first motor 31e, the second motor 42, the third motor, the first electric push rod 31b, and the third electric push rod 6 are simultaneously turned off. At this time,

[0142] The suspension plate 45 is driven by the third motor to switch from the inclined state to the horizontal state;

[0143] The second sliding block 43 returns to the initial position under the drive of the second motor 42;

[0144] The first sliding block 31d is driven by the first motor 31e to retract to the initial position, causing the second-layer handle 12 to retract into the double-layer storage box 1. At the same time, the first storage bag 2 is driven by the first sliding block 31d to switch from the inclined state to the horizontal state;

[0145] The second storage bag 5 is driven by the third electric push rod 6 to fit against the inner surface of the box cover 13, facilitating the closing of the box cover 13;

[0146] The push rod part of the first electric push rod 31b gradually retracts until the push rod of the first electric push rod 31b completely retracts to the initial position. At this time, the box cover 13 is completely closed under the drive of the first electric push rod 31b, realizing the storage of the medical device.

[0147] The content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.
