Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to a sterile forceps storage container. Background Technology
[0002] In medical care, surgical procedures, and various aseptic techniques, sterile forceps play a crucial role, serving as one of the core instruments for ensuring aseptic operation and protecting patient safety. To maintain their sterility, sterile forceps are typically stored properly in dedicated storage containers. These containers are designed to create and maintain a highly sterile environment, effectively preventing the intrusion of external microorganisms and thus avoiding serious adverse consequences such as cross-infection caused by instrument contamination. This is of great significance for patient recovery and medical safety.
[0003] However, many traditional sterile forceps storage containers have flawed lid designs. While the lids have notches, this design, perhaps intended for ease of use, can easily lead to healthcare workers accidentally touching the sterile forceps inside due to the uncertainty of the operation when opening or closing the lid. This accidental contact can contaminate the forceps, damaging their sterile barrier and affecting the sterility and reliability of subsequent use, posing a potential risk to medical procedures. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a sterile forceps storage container. This solution addresses the problem that when opening or closing the lid of an existing storage container, the sterile forceps inside the container are easily touched due to operational uncertainties. This can lead to contamination of the forceps, damage to their surface sterility barrier, and consequently affect the sterility and reliability of subsequent use, posing a potential risk to medical procedures.
[0005] To achieve the above objectives, this utility model provides a sterile forceps storage container, comprising: a container body and a container lid, wherein the container lid is hinged to the container body by a torsion spring, a locking block is fixedly connected to the container lid, and a locking block matching the locking block is slidably connected to the container body, the locking block being used to open or close the container lid.
[0006] This design, through the interlocking of the locking block and the latching block, completes the closing of the can lid. Then, by sliding the latching block, the locking block and the latching block are disengaged, and the can lid immediately springs back open under the initial preload of the torsion spring, thus completing the opening of the can lid. Throughout the opening and closing process of the can lid, it effectively prevents medical staff from accidentally touching the sterile forceps, thereby avoiding contamination of the sterile forceps, ensuring the normal use of the sterile forceps in subsequent procedures, and reducing the potential risks of medical operations caused by the sterility of the sterile forceps.
[0007] Furthermore, both the card block and the locking block have L-shaped sides, and the card block and the locking block interlock with each other; the sliding direction of the locking block is set along the circumference of the tank body.
[0008] Furthermore, a first sliding groove is fixedly installed on the tank body, and one end of the locking block is slidably connected in the first sliding groove. The length of the first sliding groove is longer than the sum of the length of the locking block and the length of the locking block.
[0009] Furthermore, a sliding block is fixedly connected to one side of the locking block, and the sliding block is provided with multiple protrusions.
[0010] Furthermore, a sliding rod is installed inside the tank, a sliding plate is slidably connected to the sliding rod, and a spring is provided between the sliding plate and the bottom plate inside the tank.
[0011] The sliding direction of the sliding plate and the contraction direction of the spring are both parallel to the central axis of the tank.
[0012] A first limiting block is detachably installed at the top of the sliding rod.
[0013] Furthermore, the top of the sliding rod is fixedly connected with an external thread, and the first limiting block is threadedly connected to the top of the sliding rod.
[0014] Furthermore, the sliding plate has several first through holes, and the edge of the sliding plate is in contact with the inner wall of the tank.
[0015] Furthermore, a screw is rotatably installed inside the tank, and an installation through hole is opened at the bottom of the tank. One end of the screw passes through the installation through hole and is fixedly connected to a second limiting block. A sealed bearing is fixedly sleeved between the installation through hole and the screw.
[0016] The screw is located on the central axis of the tank body. One end of the screw inside the tank body is integrally formed with an external thread. A movable plate is threadedly connected to the screw, and the movable plate is slidably connected to the inner wall of the tank body.
[0017] Furthermore, a second sliding groove is provided on the inner wall of the tank, and a second slider is fixedly connected to the movable plate. The second slider is slidably connected in the second sliding groove, and the direction of the second sliding groove is parallel to the central axis of the tank.
[0018] Furthermore, a sealing ring is provided between the tank body and the tank cover.
[0019] The beneficial effects of this embodiment are as follows:
[0020] 1. The can lid is closed by locking the locking block and the locking block. Then, the locking block is slid to disengage from the locking block. The can lid then immediately springs open under the initial preload of the torsion spring, thus opening the can lid. Throughout the opening and closing process, medical staff can be effectively prevented from accidentally touching the sterile forceps, thus avoiding contamination of the sterile forceps, ensuring the normal use of the sterile forceps, and reducing the potential risks of medical operations caused by the sterility of the sterile forceps.
[0021] 2. Utilizing the elastic potential energy of the spring, when the lid is opened, the sliding plate moves upward under the elastic deformation of the spring, thereby allowing the sterile forceps to extend out of the canister opening. Medical staff do not need to put their hands into the canister, reducing contact between their hands and the environment inside the canister, thus reducing the risk of contaminating sterile instruments.
[0022] 3. By rotating the screw, the specific height of the moving plate inside the container can be controlled, making it easier for medical staff to pick up sterile forceps; at the same time, it can also prevent medical staff from touching the inside of the container when picking up sterile forceps, thus avoiding contamination of the inside of the container.

Moreover, those skilled in the art will understand that the illustrations provided herein are for illustrative purposes and are not necessarily drawn to scale.
[0036] Please see Figure 1-2 This utility model provides an embodiment of a sterile forceps storage container, comprising: a container body 1 and a lid 2. The lid 2 is hinged to the container body 1 by a torsion spring 3. A locking block 4 is fixedly connected to the lid 2, and a locking block 41 matching the locking block 4 is slidably connected to the container body 1. The locking block 41 is used to open or close the lid 2. When the lid 2 needs to be closed, the lid 2 is pressed against the container body 1, and then the locking block 41 is slid, so that the locking block 41 and the locking block 4 lock together, achieving the effect of sealing the container body 1. When the lid 2 needs to be opened, the locking block 41 is slid again, so that the locking block 41 and the locking block 4 disengage. At this time, the lid 2 springs open in the opposite direction under the initial preload of the torsion spring 3, thus completing the opening of the lid 2. Throughout the opening and closing process of the canister lid 2, medical staff can be effectively prevented from accidentally touching the sterile forceps, thereby avoiding contamination of the sterile forceps, ensuring the normal use of the sterile forceps, and reducing the potential risks of medical operations caused by the sterility of the sterile forceps.
[0037] Please see Figure 1An installation box is fixedly installed on one side of the tank body 1, and an installation rod is fixedly connected to the installation box. A torsion spring 3 is movably sleeved on the installation rod. One end of the torsion spring 3 is fixedly connected inside the installation box, and the other end of the torsion spring 3 is fixedly connected to the tank lid 2. When the torsion spring 3 is in the initial position, the tank lid 2 is in the open position.
[0038] Please see Figure 4 In this embodiment, a sealing ring 11 is provided between the can body 1 and the can lid 2, and the sealing ring 11 is fixedly installed on the top of the can body 1. After the can lid 2 is placed on the can body 1 by the latching block 4 and the locking block 41, the sealing ring 11 is locked between the can body 1 and the can lid 2, filling the gap between the can body 1 and the can lid 2, forming a physical barrier, effectively preventing bacteria, viruses and other microorganisms in the air from entering the can, and ensuring the sterility of the sterile forceps during storage. The sealing ring 11 can be made of silicone.
[0039] Please see Figure 2 and Figure 4 In this embodiment, both the locking block 4 and the locking block 41 have L-shaped sides, and the locking block 4 and the locking block 41 interlock with each other. The sliding direction of the locking block 41 is set along the circumference of the tank body 1. When the locking block 4 and the locking block 41 interlock, a hook-like mechanical structure is formed. This design has extremely high anti-separation capability in the direction perpendicular to the interlocking surface, which can effectively prevent the tank body 1 from accidentally separating from the tank cover 2 and ensure structural stability. At the same time, the locking block 41 slides along the circumference of the tank body 1. This direction is perpendicular to the main force axis of the tank body 1, which can avoid structural displacement caused by radial sliding. The circumferential sliding trajectory is synchronized with the contour of the tank body 1, so that the interlocking connection is always in the optimal stress state, further enhancing the stability of the overall structure. When the locking block 41 slides along the circumferential direction, the L-shaped interlocking structure can simultaneously achieve engagement or disengagement; the operation can be completed by sliding the locking block 41 without disassembling other parts, which greatly shortens the operation time and improves work efficiency.
[0040] Please see Figure 2 and Figure 4 In this embodiment, a first slide groove 42 is fixedly installed on the tank body 1. One end of the locking block 41 is slidably connected in the first slide groove 42. The length of the first slide groove 42 is longer than the sum of the lengths of the locking block 4 and the locking block 41. The locking block 41 slides along the first slide groove 42, and the length of the first slide groove 42 is sufficient for the locking block 41 to completely disengage from the locking block 4, thereby ensuring the smooth completion of the unlocking operation.
[0041] Please see Figure 2In this embodiment, a sliding block 43 is fixedly connected to one side of the locking block 41, and the sliding block 43 is provided with a plurality of protrusions 44. When it is necessary to slide the locking block 41, medical staff can place their fingers on the sliding block 43 and slide the locking block 41 quickly, which improves the comfort of use; at the same time, the protrusions 44 on the sliding block 43 increase the friction between the fingers and the sliding block 43, which can effectively prevent slippage.
[0042] This embodiment also includes a timer. In actual use, the timer can be fixedly installed on the tank 1, for example, by adhesive bonding; it can also be detachably installed on the tank 1, for example, by magnetic adsorption; or it can be placed beside the tank 1. When it is necessary to soak sterile forceps, after placing the sterile forceps into the tank 1 and closing the tank lid 2, turn on the timer switch to start timing. When the soaking time is reached, the timer will sound an alarm to remind the staff; the timer can also be used to time the time the tank lid 2 is open and the time the sterile forceps are stored, to standardize the operating procedure and ensure the sterility of the tank 1. In actual use, the timer can be a Baijie electronic timer (e.g., CYD-96), as the timer is an existing device, it will not be described in detail here.
[0043] Example 1:
[0044] Please see Figure 3 In this embodiment, a sliding rod 6 is installed inside the canister 1, and a sliding plate 62 is slidably connected to the sliding rod 6. A spring 61 is provided between the sliding plate 62 and the bottom plate inside the canister. The spring 61 is sleeved on the sliding rod 6, with one end of the spring 61 abutting against the bottom plate inside the canister and the other end abutting against the bottom of the sliding plate 62. The sliding direction of the sliding plate 62 and the contraction direction of the spring 61 are both parallel to the central axis of the canister. A first limiting block 64 is detachably installed at the top of the sliding rod 6. After the sterile forceps are placed into the canister and the canister lid 2 is closed, the sliding plate 62 is pressed down by the sterile forceps, thereby compressing the spring 61. When the canister lid 2 is opened, the sliding plate 62 moves upward under the elastic deformation of the spring 61, thereby allowing the sterile forceps to extend out of the canister opening. Medical personnel do not need to put their hands into the canister, reducing contact between their hands and the environment inside the canister, thus reducing the risk of contaminating sterile instruments. The first limiting block 64 is used to prevent the sliding plate 62 from detaching from the sliding rod 6. Meanwhile, the entire retrieval process is efficient and quick, improving the work efficiency of medical staff. In actual use, spring 61 can be selected with a large elastic potential energy to facilitate smooth reset after the lid 2 is opened; and the first end of spring 61 can be fixedly connected to the bottom of sliding plate 62, and the other end can be fixedly connected to the bottom of sliding plate 62. One end of sliding rod 6 can be snapped or threaded into the can body for easy disassembly and cleaning later.
[0045] Please see Figure 3In this embodiment, the top of the sliding rod 6 is fixedly connected with an external thread, and the first limiting block 64 is threadedly connected to the top of the sliding rod 6. This facilitates the later disassembly and cleaning of the first limiting block 64.
[0046] Please see Figure 3 In this embodiment, the sliding plate 62 has several first through holes 63, and the edge of the sliding plate 62 is in contact with the inner wall of the tank 1. This prevents the sterile forceps from falling along the gap between the sliding plate 62 and the inner wall of the tank 1 during sliding, as the plane of the sliding plate 62 is smaller than the plane inside the tank 1. This would not only make it inconvenient to handle the sterile forceps, but could also cause damage to the sterile forceps or the tank 1. The first through holes 63 facilitate the normal flow of liquids such as disinfectant within the tank 1.
[0047] The specific usage method of this embodiment is as follows:
[0048] When in use, place the sterile forceps into the canister 1, press the canister lid 2 against the canister 1, and then slide the locking block 41 along the first sliding groove 42 so that the locking block 41 and the locking block 4 interlock, thereby closing the canister lid 2.
[0049] At this point, the timer can be turned on to calculate the time the sterile forceps are stored in container 1.
[0050] When it is necessary to open the can lid 2, slide the locking block 41 along the first slide groove 42 to disengage the locking block 41 from the locking block 4. At this time, the can lid 2 will spring open in the opposite direction under the initial preload of the torsion spring 3, thus completing the opening of the can lid 2.
[0051] When the can lid 2 is opened, the sliding plate 62 moves upward under the elastic deformation of the spring 61, thereby allowing the sterile forceps to extend out of the can opening, making it easier for medical staff to take the sterile forceps.
[0052] Example 2:
[0053] Please see Figure 5In this embodiment, a screw is rotatably installed inside the tank body 1. A mounting through hole is provided at the bottom of the tank body 1. One end of the screw 52 passes through the mounting through hole and is fixedly connected to a second limiting block 54. A sealing bearing 55 is fixedly sleeved between the mounting through hole and the screw 52. The screw 52 is located on the central axis of the tank body 1. One end of the screw 52 inside the tank body 1 is integrally formed with an external thread. A movable plate 53 is threadedly connected to the screw 52, and the movable plate 53 is slidably connected to the inner wall of the tank body 1. When it is necessary to slide the movable plate 53 up and down, medical personnel hold and rotate the second limiting block 54, thereby rotating the screw 52, causing the movable plate 53 to rise or fall along the external thread on the screw 52, thus achieving the effect of sliding the movable plate 53 up and down along the screw 52. Additionally, the second limiting block 54 prevents the screw 52 from moving arbitrarily upwards along the mounting through hole. In practical applications, the NSK 693ZZ bearing can be selected for sealing bearing 55. The NSK 693ZZ bearing is a deep groove ball bearing with an inner diameter of 3mm, an outer diameter of 8mm, and a thickness of 4mm. It is suitable for the medical device field. Its compact size and good sealing performance make it an ideal choice for medical equipment.
[0054] Please see Figure 5 In this embodiment, the movable plate 53 has several second through holes, and the edge of the movable plate 53 fits against the inner wall of the tank 1. This prevents the sterile forceps from falling along the gap between the movable plate 53 and the inner wall of the tank 1 during the lifting and lowering process, because the size of the movable plate 53 is smaller than the internal size of the tank 1. This would not only make it inconvenient to handle the sterile forceps, but could also cause damage to the sterile forceps or the tank 1. The second through holes also facilitate the normal flow of liquids such as disinfectant within the tank 1.
[0055] Please see Figure 5 In this embodiment, a second sliding groove 51 is provided on the inner wall of the tank 1, and a second slider is fixedly connected to the moving plate 53. The second slider is slidably connected within the second sliding groove 51, and the direction of the second sliding groove 51 is parallel to the central axis of the tank 1. If the tank 1 is cylindrical, the moving plate 53 will not rotate with the screw 52 when the screw 52 is rotated, thereby avoiding the situation where the screw 52 rotates ineffectively, allowing the moving plate 53 to move smoothly up and down along the second sliding groove 51. The second sliding groove 51 and the second slider can be symmetrically arranged, so that the moving plate 53 can slide more smoothly up and down.
[0056] The specific usage method of this embodiment is as follows:
[0057] When in use, place the sterile forceps into the canister 1, press the canister lid 2 against the canister 1, and then slide the locking block 41 along the first sliding groove 42 so that the locking block 41 and the locking block 4 interlock, thereby closing the canister lid 2.
[0058] At this point, the timer can be turned on to calculate the time the sterile forceps are stored in container 1.
[0059] When it is necessary to open the can lid 2, slide the locking block 41 along the first slide groove 42 to disengage the locking block 41 from the locking block 4. At this time, the can lid 2 will spring open in the opposite direction under the initial preload of the torsion spring 3, thus completing the opening of the can lid 2.
[0060] When the can lid 2 is opened, medical staff can grasp and rotate the second limiting block 54, thereby rotating the screw 52, causing the moving plate 53 to rise along the external thread on the screw 52, so that the sterile forceps can be extended out of the can body 1, making it easier for medical staff to take the sterile forceps.
[0061] In summary, this invention achieves the closing of the can lid 2 by interlocking the locking block 4 and the locking block 41. Then, by sliding the locking block 41, the locking block 41 disengages from the locking block 4, and the can lid 2 immediately springs open under the initial preload of the torsion spring, thus completing the opening of the can lid 2. Throughout the opening and closing process of the can lid 2, it effectively prevents medical personnel from accidentally touching the sterile forceps, thereby preventing contamination of the sterile forceps, ensuring the normal use of the sterile forceps, and reducing the potential risks of medical operations due to the sterility of the sterile forceps. Therefore, this invention effectively overcomes the various shortcomings of the prior art.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
