Description

Technical Field

[0001] This invention relates to the field of storage device technology, and in particular to a sterile storage and clamping device for ophthalmic microsurgical instruments. Background Technology

[0002] Ophthalmic microsurgical instruments are mostly high-precision and delicate instruments with fragile tips that are prone to deformation, wear, and impact damage. Furthermore, they come into direct contact with ocular tissue during surgery, requiring extremely high sterility. Therefore, postoperative disinfection and sterile storage of microsurgical instruments are essential to ensure surgical safety and the accuracy of instrument reuse. Currently, most clinical disinfection and storage devices for ophthalmic microsurgical instruments rely solely on various independent mechanical structures such as slots, clips, spring clips, and fixing brackets to limit and fix the instruments. Disinfectant solutions only perform sterilization and cannot provide auxiliary limiting or restraining effects on instruments in the soaking state.

[0003] To ensure that instruments do not shift, shake, or collide with each other during disinfection and storage, existing technologies require a large number of complex mechanical limiting mechanisms inside the device. The overall structure is cumbersome and has many parts, which not only significantly increases the manufacturing cost and overall size and weight of the device, resulting in extremely poor portability and inconvenience for transfer between operating rooms, outpatient clinics, and disinfection departments, but also greatly increases the difficulty of operation for medical staff. During the storage, placement, and retrieval of instruments, medical staff need to complete multiple operations such as alignment, locking, and unlocking one by one. The operation process is cumbersome, time-consuming, and inefficient.

[0004] Meanwhile, the numerous mechanical limiting structures come into contact with precision instruments at multiple points, easily creating blind spots for disinfection at these contact points, leading to incomplete instrument disinfection and potential medical safety hazards. Furthermore, the repeated contact and friction between rigid mechanical components and the tips of delicate instruments can easily cause wear, impact, and deformation of the instrument tips, severely affecting the accuracy and lifespan of ophthalmic microsurgical instruments. In summary, existing sterile storage and disinfection devices for ophthalmic microsurgical instruments have many shortcomings, including complex structure, poor portability, cumbersome operation, incomplete disinfection, and poor instrument protection, making it difficult to meet the clinical needs for precise, efficient, and convenient instrument disinfection, storage, and use. Summary of the Invention

[0005] The main objective of this invention is to provide a sterile storage and clamping device for ophthalmic microsurgical instruments, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A sterile storage and holding device for ophthalmic microsurgical instruments includes a storage box with a cover plate at the top. Handles are fixedly connected to the left and right sides of the upper end of the cover plate. A leakage component is fixedly installed on the middle of the left side wall and the middle of the right side wall of the inner surface of the storage box. A placement component is fixedly installed on the upper part of the outer surface of the leakage component. A floating component is fixedly installed on the lower part of the outer surface of the placement component. A tensioning component is slidably installed on the inner surface of the placement component.

[0008] Preferably, a drain pipe is fixedly connected to the lower middle part of the left end and the lower middle part of the right end of the storage box. Both drain pipes are in communication with the inner cavity of the storage box. Both drain pipes have threaded caps threadedly connected to their inner surfaces. A disinfection lamp is fixedly connected to the upper surface of the inner surface of the storage box.

[0009] Preferably, the leakage assembly includes a leakage plate that is fixedly connected to the middle of the left side wall and the middle of the right side wall of the inner surface of the storage box. The upper end of the leakage plate has a plurality of leakage holes arranged in a linear array, and the upper end of the leakage plate has a plurality of limiting holes arranged in a linear array, with the plurality of limiting holes located between the plurality of leakage holes.

[0010] Preferably, the floating assembly includes a floating plate, and the lower end of the floating plate has a plurality of water inlet grooves arranged in a linear array, and the floating plate is located below the drain plate.

[0011] Preferably, the placement assembly includes a placement plate, with a plurality of sliding rods linearly and fixedly connected to the lower end of the placement plate, a plurality of rectangular holes linearly and arranged on the front and rear sides of the upper end of the placement plate, and a plurality of protrusions fixedly connected to the upper end of the placement plate.

[0012] Preferably, the plurality of sliding rods are located on the inner surface of the plurality of limiting holes, and the lower ends of the plurality of sliding rods are all fixedly connected to the upper end of the floating plate.

[0013] Preferably, the tensioning assembly includes a plurality of support rods, which are respectively located inside a plurality of rectangular holes. Any two adjacent support rods are fixedly connected to a tensioning band at their upper ends. A plurality of leakage holes are provided on the outer surface of each tensioning band. The lower ends of the plurality of support rods are fixedly connected to the upper end of the leakage plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention abandons the traditional complex mechanical limiting mechanism and uses a floating component to automatically drive the placement plate to move up and down with the rise and fall of the liquid level. This, in turn, links the tensioning strap to achieve flexible tension and fixation of the instruments, eliminating the need for tedious operations such as individual clamping and locking. At the same time, the drain plate and the limiting hole, together with the sliding rod, not only achieve guiding and limiting but also complete the drainage function. It is multi-functional, reduces the number of parts, and has a compact and lightweight structure, reducing manufacturing costs and size and weight. It is convenient for transportation and carrying between operating rooms, outpatient clinics and disinfection departments. Medical staff only need to place the instruments, inject the fluid, and drain the fluid to complete the storage and retrieval. The operation process is simplified and effectively improves the efficiency of clinical work.

[0016] 2. This invention uses protrusions on the placement plate to support the lower side of the instrument, allowing disinfectant to flow over the bottom surface. Several perforations are created in the tension band to ensure that the area where the upper surface of the instrument contacts the tension band remains in contact with the disinfectant. A disinfection lamp is installed inside the storage box, providing high-temperature and ultraviolet-assisted sterilization. Disinfectant flows from both sides of the placement plate into the leakage plate, collects through the leakage holes on the lower side of the box, achieving dynamic flow rinsing. Compared to traditional rigid slots with multiple points of contact creating blind spots, this solution uses a flexible tension band with point-like contact combined with a porous permeable design, reducing the obstructed area and ensuring that all surfaces of the instrument are fully immersed and irradiated, resulting in more thorough disinfection and eliminating potential medical safety hazards.

[0017] 3. This invention uses a tension band as the fixing medium. Its flexible material replaces traditional rigid buckles and spring clips, avoiding hard friction and collisions with the instrument tips. When the floating board floats, the tension band only applies uniform tension to the front and back sides of the instrument, making the instrument firmly attached to the placement board without local stress concentration. At the same time, the tension band has a small contact area with the instrument and is made of soft material, which is not easy to cause wear or deformation. After drainage, the floating component resets and the tension is automatically released. There is no additional unlocking operation when removing the instrument, reducing accidental damage caused by human touch. This design effectively protects the integrity and service life of the precision tips of microsurgical instruments and meets the protection requirements of high-precision instruments in clinical practice.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sterile storage and clamping device for ophthalmic microsurgical instruments includes a storage box 1 with a cover plate 2 at the upper end of the storage box 1. A handle 3 is fixedly connected to the upper left and upper right sides of the cover plate 2. A leakage component 4 is fixedly installed in the middle of the left side wall and the middle of the right side wall of the inner surface of the storage box 1. A placement component 6 is fixedly installed on the upper part of the outer surface of the leakage component 4. A floating component 5 is fixedly installed on the lower part of the outer surface of the placement component 6. A tensioning component 7 is slidably installed on the inner surface of the placement component 6.

[0029] In use, the instruments to be stored on the cover plate 2 are first placed on the upper side of the placement component 6 by holding the handles 3 on both sides. Then, the disinfectant required for disinfection and cleaning is sprayed into the inner cavity of the storage box 1 using the spraying device in the existing technology. During the spraying process, the disinfectant is sprayed onto the surface of the instruments. The disinfectant then flows from both sides of the placement component 6 to the upper side of the leakage component 4. The leakage component 4 not only limits and guides the placement component 6, but also guides the used disinfectant into the lower side of the inner cavity of the storage box 1. After the used disinfectant accumulates in the lower side of the inner cavity of the storage box 1, the floating component 5 floats upward. The floating component 5 then moves the placement component 6, causing the tensioning component 7 to tighten the tilted part placed on the upper side of the placement component 6, so as to facilitate the subsequent high-temperature disinfection operation.

[0030] This embodiment achieves the overall simplification of the device by linking the floating component 5 and the tensioning component 7, eliminating the need for a large number of complex mechanical limiting structures, reducing the size and weight, and facilitating transfer between the operating room and the sterilization department. At the same time, medical staff only need to complete simple steps such as placement, spraying, and drainage to fix and remove the instruments, reducing the complexity of operation and improving clinical work efficiency.

[0031] The spraying device mentioned above is a conventional setup in the prior art. In this solution, it is only necessary to spray the disinfectant into the inner cavity of the storage box 1. The specific spraying equipment and spraying method can be adjusted according to actual usage requirements, so this solution will not elaborate on them in detail.

[0032] Example 2, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, drain pipes 81 are fixedly connected to the lower middle of the left end and the lower middle of the right end of the storage box 1. Both drain pipes 81 are connected to the inner cavity of the storage box 1. Threaded caps 82 are threadedly connected to the inner surfaces of both drain pipes 81. A disinfection lamp 10 is fixedly connected to the upper surface of the inner surface of the storage box 1.

[0033] Furthermore, the leakage component 4 includes a leakage plate 41 that is fixedly connected to the middle of the left side wall and the middle of the right side wall of the inner surface of the storage box 1. The upper end of the leakage plate 41 has a plurality of leakage holes 42 linearly arranged, and the upper end of the leakage plate 41 has a plurality of limiting holes 43 linearly arranged, with the plurality of limiting holes 43 located between the plurality of leakage holes 42.

[0034] Furthermore, the floating assembly 5 includes a floating plate 51, with a plurality of water inlet grooves 52 linearly arrayed at the lower end of the floating plate 51, and the floating plate 51 is located below the drain plate 41.

[0035] Furthermore, the placement component 6 includes a placement plate 61, with a plurality of sliding rods 62 linearly and fixedly connected to the lower end of the placement plate 61, and a plurality of rectangular holes 63 linearly and fixedly opened on the front and rear sides of the upper end of the placement plate 61, and a plurality of protrusions 64 fixedly connected to the upper end of the placement plate 61.

[0036] Furthermore, several sliding rods 62 are located on the inner surface of several limiting holes 43, and the lower ends of several sliding rods 62 are fixedly connected to the upper end of the floating plate 51.

[0037] Furthermore, the tensioning assembly 7 includes several support rods 71, which are located inside several rectangular holes 63. Any two adjacent support rods 71 ​​are fixedly connected to a tensioning band 72 at their upper ends. Several leakage holes 73 are opened on the outer surface of the tensioning bands 72. The lower ends of the support rods 71 ​​are fixedly connected to the upper end of the leakage plate 41.

[0038] In the process of using this solution, the instruments to be stored are first placed on the upper side of the placement plate 61 in sequence, so that the front and rear sides of the instruments are located below the front and rear holes 73 respectively.

[0039] Then, the disinfectant required for cleaning and disinfection can be sprayed into the inner cavity of the storage box 1. When the disinfectant is sprayed into the inner cavity of the storage box 1, it will be sprayed on the surface of the instrument. Then the disinfectant will flow downward along the cavity between the left and right sides of the placement plate 61 and the storage box 1. And because several protrusions 64 are fixedly connected to the upper end of the placement plate 61, the protrusion of the protrusions 64 will support the lower side of the instrument so that the disinfectant can pass through the lower side of the instrument.

[0040] The disinfectant water flowing into the lower side of the storage box 1 will enter the lower side of the inner cavity of the storage box 1 through several leakage holes 42 opened at the upper end of the leakage plate 41, and then be stored in the lower side of the inner cavity of the storage box 1. When the amount of disinfectant water collected in the lower side of the inner cavity of the storage box 1 increases, since the inner cavity of the float plate 51 is hollow and several water inlet grooves 52 opened on the lower side of the float plate 51 can allow some disinfectant water to flow to the lower side of the float plate 51. Then, under the action of buoyancy, the float plate 51 floats upward in the inner cavity of the storage box 1.

[0041] When the float plate 51 floats upward, it can cause the upper end of the float plate 51 to drive several sliding rods 62 to move upward. When the several sliding rods 62 move upward, under the limiting and guiding action of several limiting holes 43, the placement plate 61 can be prevented from shifting. When the placement plate 61 moves upward, since several support rods 71 ​​are located inside several rectangular holes 63 respectively, and several support rods 71 ​​are fixedly connected to the upper end of the leakage plate 41, the distance between the tensioning band 72 on the same side and the placement plate 61 can be reduced, thereby allowing the tensioning band 72 to tighten the front and back sides of the instrument at the same time.

[0042] Then, by holding the handles 3 on both sides, the cover plate 2 can be closed on the upper side of the storage box 1. At this time, by turning on the disinfection lamp 10, the high temperature generated by the disinfection lamp 10 will disinfect the inclined device held inside the tension straps 72. Furthermore, by opening several holes 73 at the upper end of the tension straps 72, the overall disinfection area of ​​the device can be increased.

[0043] When the instruments need to be retrieved later, simply rotate the threaded caps 82 on both sides to open them, so that the disinfectant stored in the lower part of the inner cavity of the storage box 1 can be discharged from the drain pipes 81 on both sides. Then the floating component 5 and the placement component 6 are returned to their initial positions. Then the cover plate 2 can be opened to take out the cleaned and disinfected instruments. This operation is the opposite of the above operation, so this solution will not elaborate on it further.

[0044] In this embodiment, the protrusion 64 props the bottom of the instrument away from the placement plate 61, preventing the bottom of the instrument from sticking tightly to the plate and forming an obstruction. At the same time, the leakage hole 73 on the tension strap 72 allows the disinfectant to penetrate and contact the upper surface of the instrument, effectively eliminating the disinfection dead corners caused by traditional rigid supports, ensuring that all parts of the instrument can be fully soaked. In combination with the disinfection lamp 10, a more thorough sterilization effect can be achieved.

[0045] The tension band 72 is a flexible band that applies a uniformly distributed elastic tension force to the instrument, rather than a point-like squeezing force from a rigid component. This effectively prevents the instrument tip from repeatedly rubbing or bumping against hard materials, preventing deformation and wear of precision instruments, thus ensuring the accuracy and lifespan of the instruments. Furthermore, the tension force is automatically released after drainage, eliminating the need for additional unlocking action, further simplifying the removal process and preventing damage to the instruments due to human error.

[0046] The disinfection lamp 10 mentioned above is an ultraviolet lamp in the prior art. In this solution, it is only necessary to ensure that it generates high temperature and ultraviolet light during use to disinfect the instruments. Its specific installation method, circuit connection method and control method are all conventional designs, so this solution will not elaborate on them in detail.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
