Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to a surgical specimen storage box. Background Art

[0002] In medical practice, specimens generated during surgery are extremely valuable for the diagnosis, treatment, and subsequent research of diseases. These specimens need to be properly preserved and processed to ensure their integrity and reliability, providing an accurate basis for doctors' decision-making.

[0003] There are many specimens in gynecological and cardiothoracic surgeries. For example, when patients with cervical cancer undergo gynecological extensive total hysterectomy, in addition to specimens of the entire uterus and bilateral adnexa, the corresponding lymph node groups must also be cleared to prevent the possibility of lymph node metastasis after cancer cells invade the lymph nodes. There are about 8-10 small specimens of uterine lymph nodes. Similarly, in cardiothoracic surgery for radical resection of lung cancer, in addition to specimens on the side of the lesion, the corresponding lymph node groups must also be cleared. The specimens are small and numerous. The removed lymph nodes need to be collected and stored as specimens, so that they can be sent for pathological examination and provide a basis for clinical treatment.

[0004] For example, a surgical specimen box disclosed in the authorization announcement number CN220786586U can limit the protective cover by the cooperation of the limiting block and the fixed block. The user can move the limiting plate through the push plate, and then the limiting block can be separated from the fixed block. The operation is simple, and the protective cover can be fixed and opened quickly. However, in the structure of the surgical specimen box, when the protective cover is opened to take out one of the specimens, if other storage boxes are not in a sealed state, they will come into contact with the air to accelerate air drying, and the storage box needs to be sealed with a sealing plate and a metal plate. When taking out, it is necessary to use the magnet on the connecting rod to remove the sealing plate from the storage box through the metal plate, so that the storage box is in an open state for personnel to take out the specimen. There are complex structures and many specimen storage steps, which increase the storage time of a single specimen and affect efficiency. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0036] like Figures 1 to 8As shown, a surgical specimen storage box comprises an outer shell 1 and a box body 2, wherein the outer shell 1 has a receiving cavity 12; the box body 2 is slidably connected to the inner wall of the receiving cavity 12, and the box body 2 can be slid to reveal itself outwardly and retracted inwardly to close the receiving cavity 12; the box body 2 has a plurality of first compartments 21 and second compartments 22 for storing specimens, and a third compartment 23 for placing surgical tools; the first compartments 21 and the second compartments 22 are both rotatably provided with cover plates 24 at the open positions, and the cover plates 24 are both rotatable to close and open the openings; wherein, a fixing rod 25 is provided on the top of the cover plates 24, and a limiting plate 3 cooperating with the fixing rod 25 is provided in the receiving cavity 12; the box body 2 slides and retracts into the receiving cavity 12, and the limiting plate 3 abuts against the fixing rod 25, so that the cover plate 24 and the box body 2 are tightly fitted to close and seal the opening.

[0037] Specifically, the box body 2 is provided with a first compartment 21 for storing conventional specimens, a second compartment 22 for storing rapid specimens, and a third compartment 23 for placing surgical tools; the third compartment 23 is located in front of the first compartment 21 and the second compartment 22, the second compartment 22 is located in the middle of the box body 2, and a plurality of first compartments 21 are respectively distributed on the left and right sides of the second compartment 22. Such a structural design is helpful for classifying and storing specimens, thereby improving the efficiency and convenience of storage. A rotatable cover plate 24 is provided at the open position of the first compartment 21 and the second compartment 22; when it is necessary to place or remove specimens in the first compartment 21 or the second compartment 22, the medical staff can rotate the cover plate 24 to open it; and when it is not needed, the cover plate 24 can be rotated back to its original position, closing the corresponding first compartment 21 or the second compartment 22 to prevent the specimens from being contaminated or damaged, and at the same time preliminarily sealing the specimens to avoid long-term contact with the outside air, effectively delaying the drying of the specimens. The box body 2 is slidably connected to the inner wall of the accommodating cavity 12, so that the box body 2 can slide outward to be exposed as needed, so that medical staff can easily place or remove surgical specimens and tools therein; at the same time, the box body 2 can also retract inward to completely seal the accommodating cavity 12, thereby ensuring the safe storage of specimens and tools.

[0038] The utility model provides a fixing rod 25 on the top of the cover plate 24, and a limiting plate 3 cooperating with the corresponding fixing rod 25 is provided inside the accommodating chamber 12. When the box body 2 retracts inward into the accommodating chamber 12, the limiting plate 3 will abut against the fixing rod 25, and through physical action, the rotation of the cover plate 24 is restricted and the fixing rod 25 is pressed downward, so that the cover plate 24 and the box body 2 are tightly fitted, and the openings of the first sub-grid 21 and the second sub-grid 22 are further sealed, thereby improving the sealing effect, effectively ensuring the safety of the specimen in the preservation box, and achieving a good storage effect of the specimen. At the same time, when the box body 2 is pulled out of the accommodating chamber 12 and the first sub-grid 21 and the second sub-grid 22 are exposed, the cover plate 24 is automatically unlocked, and the corresponding first sub-grid 21 or second sub-grid 22 is opened to take out the specimen without affecting the storage of other specimens, thereby improving the specimen storage effect; when the box body 2 retracts into the accommodating chamber 12, the first sub-grid 21 and the second sub-grid 22 are moved to the accommodating chamber 12 and automatically locked and limited by the fixing rod 25 and the limiting plate 3, thereby improving the convenience of specimen access. After the box body 2 is completely retracted into the accommodating chamber 12, the box body 2 cooperates with the shell 1 to close the accommodating chamber 12, and the first sub-grid 21 and the second sub-grid 22 are closed by the cover plate 24, thereby achieving a double sealing effect.

[0039] It should be noted that the number of first grids 21 is 24, the number of second grids 22 is two, the two second grids 22 are located in the middle of the box body 2, and the two second grids 22 are distributed front to back, the 24 first grids 21 are respectively arranged on both sides of the second grid 22, the number of first grids 21 on each side is 12, and the 12 first grids 21 are distributed in an array to form 3 columns, the number of first grids 21 in one column is 4, and there are 6 columns on both sides, and the number of limiting plates 3 is 7, of which 6 limiting plates 3 are respectively matched with the fixing rods 25 at the positions of the first grids 21 in 6 columns, and the other 1 limiting plate 3 is matched with the fixing rods 25 at the positions of the two second grids 22. The number of first grids 21, second grids 22, third grids 23 and limiting plates 3 is not limited, and the number and the corresponding positions can be adjusted accordingly according to actual needs.

[0040] In other embodiments, the box body 2 may be made of PVC (polyvinyl chloride) material, which has good corrosion resistance, high temperature resistance and sealing properties.

[0041] In other embodiments, the cover plate 24 can be made of a transparent material to facilitate medical staff to view the specimen. The transparent material can be one of polycarbonate, polypropylene, and polystyrene, which has good light transmittance and durability.

[0042] In other embodiments, the first grid 21 and the second grid 22 are both provided with writable marking areas, which can be written with an oil pen or a whiteboard pen. At the same time, a QR code label is provided on the outside of the box body 2, and information query and tracking can be performed by scanning the QR code.

[0043] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the side portion of the limiting plate 3 close to the opening of the accommodating cavity 12 is inclined upward to form an inclined surface 31. Specifically, the inclined surface 31 is located at the front end of the limiting plate 3, and is gradually inclined upward from the back to the front. With the setting of the inclined surface 31, when the box body 2 is retracted into the accommodating cavity 12, the fixing rod 25 first contacts the inclined surface 31, and gradually fits tightly with the box body 2 through the guidance of the inclined surface 31. At the same time, it also prevents the cover plate 24 that is not completely closed from getting stuck after contacting the limiting plate 3, thereby improving the matching stability between the fixing rod 25 and the limiting plate 3.

[0044] In some embodiments of the present application, a roller 26 is rotatably provided on the fixed rod 25, and the fixed rod 25 cooperates with the limiting plate 3 through the roller 26. Specifically, after the fixed rod 25 contacts and cooperates with the limiting plate 3 through the roller 26, the friction resistance between the two is reduced because the roller 26 is rotatable, so that the cooperation between the fixed rod 25 and the limiting plate 3 is smoother.

[0045] In some embodiments of the present application, the end surface of the cover plate 24 that contacts the box body 2 is provided with a sealing layer. Specifically, the sealing layer is provided on the end surface of the cover plate 24 that contacts the box body 2. After the cover plate 24 rotates and fits with the box body 2, the sealing layer can effectively fill the gap between the cover plate 24 and the box body 2, further improving the sealing effect and achieving good storage of the specimen. The material of the sealing layer can be selected from silicone.

[0046] In some embodiments of the present application, the housing 1 includes a guide rail 11, which is located on the inner wall of the accommodating cavity 12. A slide bar 28 slidably connected to the guide rail 11 is provided on the side of the box body 2, and one end of the slide bar 28 protrudes from the side of the box body 2 away from the open opening of the accommodating cavity 12. Specifically, the left and right side walls of the accommodating cavity 12 are provided with guide rails 11, and the left and right sides of the box body 2 are also provided with slide bars 28. The box body 2 can slide back and forth in the accommodating cavity 12 through the cooperation of the slide bar 28 and the guide rail 11. In addition, the rear end of the slide bar 28 exceeds the rear side of the box body 2, increasing the slidable range of the box body 2, so that the box body 2 can be fully extended out of the accommodating cavity 12 and exposed to the outside, ensuring that medical staff can take and place specimens well.

[0047] In some embodiments of the present application, Fig. 9 and Fig.10As shown, it also includes a guide cylinder 41, a positioning shaft 42 and an elastic member 43. The guide cylinder 41 is arranged on the inner wall of the accommodating cavity 12 and is located below the box body 2. The positioning shaft 42 slides in the guide cylinder 41. A plurality of positioning grooves 44 are arranged at the bottom of the box body 2. The plurality of positioning grooves 44 are spaced apart along the sliding direction of the box body 2. The positioning shaft 42 can be inserted into the positioning grooves 44 for positioning. The two ends of the elastic member 43 are respectively connected to the positioning shaft 42 and the guide cylinder 41. Specifically, the number of the positioning grooves 44 is 4. The elastic member 43 is a spring and is located inside the guide cylinder 41. The two ends of the elastic member 43 are respectively connected to the bottom end of the positioning shaft 42 and the bottom inside the guide cylinder 41. The box body 2 is completely retracted into the accommodating chamber 12, and the positioning shaft 42 is inserted into the positioning groove 44 located at the front side. When the box body 2 is pulled outward, the positioning shaft 42 moves out from the positioning groove 44 located at the front side, and the elastic member 43 is deformed. The box body 2 continues to slide and is positioned at three different stages of the extension of the box body 2 through the other three positioning grooves 44. In this way, the degree of extension of the box body 2 can be adjusted when taking out the specimen. The positioning groove 44 and the positioning shaft 42 are used to cooperate and position, so as to prevent the box body 2 from sliding easily when taking and placing the specimen, thereby affecting the use experience of medical staff and improving the storage and use flexibility of the present invention.

[0048] In some embodiments of the present application, a plurality of bosses 51 are provided in the third compartment 23, and a support plate 52 matching the shape of the third compartment 23 is placed on the plurality of bosses 51, the support plate 52 is a hollow structure, and a handle 53 is provided at at least one end of the support plate 52. Specifically, there are four bosses 51, which are respectively provided at the four corners of the bottom of the third compartment 23, and the four corners of the support plate 52 are supported by the four bosses 51. When it is necessary to place the surgical tool in the third compartment 23, the surgical tool is placed on the support plate 52 with a hollow structure. If there is liquid on the surgical tool, the liquid will flow through the support plate 52 into the bottom of the third compartment 23, thereby improving the placement effect of the surgical tool.

[0049] In some embodiments of the present application, the bottom of the first sub-grid 21 and the bottom of the second sub-grid 22 are at least partially recessed to form a placement groove 27. Specifically, the bottom of the first sub-grid 21 and the bottom of the second sub-grid 22 are provided with a placement groove 27, and the specimen is placed in the placement groove 27, so that the specimen can be placed in the sub-grid more stably, reducing the risk of damage to the specimen due to shaking or collision during movement or transportation. For specimens that need to be frequently taken and inspected, the design of the placement groove 27 can make it easier to take out and put back; it can not only improve work efficiency, but also reduce damage to the specimen caused by improper operation.

[0050] In some embodiments of the present application, a slide groove 8 is provided at the bottom of the shell 1, and a convex strip 7 matching the shape of the slide groove 8 is provided at the bottom of the shell 1, so that two adjacent shells 1 can be stacked through the slide groove 8 and the convex strip 7. Specifically, when multiple storage boxes need to be stored, the shells 1 of two adjacent storage boxes can be aligned up and down, and the convex strip 7 at the top of the lower shell 1 can be inserted into the slide groove 8 at the bottom of the upper shell 1 to achieve a stacking arrangement. And through the coordinated arrangement of the slide groove 8 and the convex strip 7, several storage boxes can be stacked, which effectively reduces the space occupied by the storage boxes and is more convenient for the storage and access of surgical specimens.

[0051] In other embodiments, the number of the convex strips 7 and the slide grooves 8 of the shell 1 are both two, and the two convex strips 7 are respectively distributed on two opposite sides of the top of the shell 1, and the two slide grooves 8 are respectively distributed on two opposite sides of the bottom of the shell 1. The two adjacent shells 1 are fixed by the slide grooves 8 and the convex strips 7 on both sides, so as to achieve the purpose of stacking. The number of the convex strips 7 and the slide grooves 8 is set to two, which further improves the stability of the fixation between the two adjacent storage boxes and ensures a good connection effect. The number and position of the convex strips 7 and the slide grooves 8 are not limited here, and the number of the convex strips 7 and the slide grooves 8 can be set to 3, 4, 5 or 6 according to actual needs.

[0052] In other embodiments, in order to further improve the stability of the two storage boxes after stacking, magnets with opposite magnetic properties can be respectively provided in the convex strip 7 and the slide groove 8, so as to fix the two connected storage boxes by magnetic attraction. In other embodiments, the convex strip 7 and the slide groove 8 can also be provided with mutually cooperating buckle structures to achieve the snap-fitting of the two adjacent storage boxes to fix the stacked storage boxes.

[0053] In other embodiments, the handle is a groove formed by partially recessing the front side of the box body 2 , and the groove is L-shaped when viewed from the side, so that the user can pull the box body 2 .

[0054] In some embodiments of the present application, a clamping rod 61 and a clamping block 62 are also included. The clamping block 62 is arranged on the box body 2, and a clamping groove 63 is formed between the clamping block 62 and the box body 2. The clamping rod 61 is rotatably arranged on the shell 1 and is close to the accommodating chamber 12. After the clamping rod 61 is rotated to a vertical state, the end of the clamping rod 61 can be clamped into the clamping groove 63 to limit the sliding of the box body 2. Specifically, the shape and size of the clamping groove 63 match the end of the clamping rod 61, and the clamping rod 61 can be rotated on the shell 1 to change it from a horizontal state to a vertical state. When the clamping rod 61 is rotated to a vertical state and clamped into the clamping groove 63, the sliding of the box body 2 in the accommodating chamber 12 is effectively restricted. This design ensures that the box body 2 can maintain a stable position when it does not need to be moved, and prevents damage or loss of specimens or tools caused by accidental sliding. The coordination and operation of the clamping rod 61 and the clamping block 62 are simple. Medical staff only need to gently rotate the clamping rod 61 to achieve the locking and unlocking of the box body 2, which is convenient and quick. By quickly locking and unlocking the box body 2, medical staff can store and retrieve surgical specimens and tools more efficiently, which helps to reduce unnecessary time waste and improve the overall efficiency of medical work.

[0055] It should be noted that the box body 2 can be thoroughly sterilized by ethylene oxide or other sterilization methods. Before sterilization, the cover plate 24 inside the box body 2 needs to be completely opened to ensure that the sterilizing agent can fully penetrate into every corner. After sterilization, the box body 2 needs to be placed in a dry and ventilated place to dry to avoid residual moisture affecting the use effect.

[0056] In some embodiments of the present application, an infusion assembly can be provided on the box body 2 as required, and the infusion assembly can transport the preservation liquid into the first compartment 21 and the second compartment 22 .

[0057] Preferably, the infusion assembly includes a box for storing a preservation solution, and a delivery pipeline connecting the box with each compartment (the first compartment 21 and the second compartment 22) to meet the need to deliver the preservation solution to each compartment. The preservation solution may be formalin, including but not limited to one.

[0058] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
