Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a sealing structure for sealing sterile equipment. Background Technology

[0002] During surgery, a drive block that moves on the main body of sterile instruments is often required. At this time, a sealed structure is needed to follow the movement of the drive block to ensure that the drive block remains sterile during the movement. There are usually two ways to move the existing sealed structure: (1) By reserving a section of the sterile cover's travel, the drive block is moved by folding the sterile cover. This method may result in wrinkles in the sealed structure, which may interfere with the drive block and waste the drive block's travel. (2) The drive block is moved by the gap of the misaligned double-layer sealed structure. However, this method is prone to problems such as poor sterility, convection, or accidental contact with contaminated areas.

[0003] Therefore, how to improve the sealing structure to maintain good sterility during the movement of the drive block has become an urgent problem to be solved. Summary of the Invention

[0004] The main objective of this invention is to provide a sealing structure for sealing sterile instruments, aiming to solve the technical problem of how to improve the sealing structure so that the drive block maintains a good sterility effect throughout its movement.

[0005] To achieve the above objectives, the present invention proposes a sealing structure for sealing sterile equipment, comprising a body, a sterile cover, a sterile bag, a drive block, and a guide mechanism; The sterile cover is provided with a zipper, the zipper has an opening, and the guide mechanism is located at the opening position of the zipper; The sterile bag has an opening, and the opening of the sterile bag is tightly fitted to the side of the guide mechanism away from the zipper opening. The sterile cover and the sterile bag form a sealed space. Both the machine body and the drive block are located within the sealed space. The drive block is simultaneously connected to the guide mechanism and the machine body. When the drive block moves, it drives the sterile bag and the guide mechanism to move synchronously, so that the drive block, sterile bag and guide mechanism move on the machine body at the same time, ensuring that the drive block is always wrapped by the sterile bag during the movement. The area where the zipper is closed is sealed, and the sealing structure remains sealed when the drive block moves.

[0006] Furthermore, the guiding mechanism includes an outer frame and two connectors, the outer frame being provided with zipper heads, and the connectors being disposed on the opening of the zipper.

[0007] Furthermore, the connector is provided with a sliding groove, and the outer frame can slide along the sliding groove.

[0008] Furthermore, the drive block is provided with a mounting part, and the connector is detachably connected to the mounting part; The zipper head is provided with a lower limit position, and the connector is provided with an upper limit position, which abuts against the mounting part.

[0009] Furthermore, the connector is also provided with a guide plate, and a groove is provided between the guide plate and the connector. The guide plate is located on the outside of the sterile cover, and the connector is located on the inside of the sterile cover.

[0010] Furthermore, the guide plate has a buckle on the side near the connector, and the zipper is disposed between the buckle and the groove.

[0011] Furthermore, the outer frame is also provided with an installation seam, the first end of the zipper head is fixed in the installation seam, and the second end of the zipper head engages with the zipper teeth located on the zipper.

[0012] Furthermore, the main body of the drive block is located on the side of the guide plate away from the connector, and the opening of the sterile bag is tightly fitted to the side of the connector away from the main body of the drive block.

[0013] Furthermore, the guide mechanism is detachably connected to the mounting portion located on the drive block via the connector.

[0014] Furthermore, the connector is provided with a limiting groove, and the mounting part is provided with a limiting ridge, the limiting ridge being installed in the limiting groove.

[0015] This invention discloses a sealing structure for sealing sterile equipment, comprising a body, a sterile cover, a sterile bag, a drive block, and a guide mechanism. The sterile cover has a zipper with an opening, and the guide mechanism is positioned at the opening of the zipper. The sterile bag has an opening that tightly fits against the side of the guide mechanism away from the zipper opening, forming a sealed space with the sterile cover and the sterile bag. The body and the drive block are both located within this sealed space, and the drive block is simultaneously connected to both the guide mechanism and the body. When the drive block moves, it drives the sterile bag and the guide mechanism to move synchronously, ensuring that the drive block, sterile bag, and guide mechanism move simultaneously on the body, guaranteeing that the drive block is always enveloped by the sterile bag during its movement. Simultaneously, the area where the zipper is closed is sealed, and the sealing structure maintains good sealing performance throughout the drive block's movement, ensuring that the entire sealing structure remains sealed during the drive block's movement.

[0023] Reference Figure 1 and Figure 2 This invention discloses a sealing structure for sealing sterile equipment, comprising a body 1, a sterile cover 2, a sterile bag 3, a drive block 4, and a guide mechanism 5; the sterile cover 2 is provided with a zipper 6, the zipper 6 having an opening, and the guide mechanism 5 being disposed at the opening position on the zipper 6; the sterile bag 3 has an opening, the opening of the sterile bag 3 being tightly fitted to the side of the guide mechanism 5 away from the opening of the zipper 6, the sterile cover 2 and the sterile bag 3 forming a sealed space; the body 1 and the drive block 4 are both disposed within the sealed space, and the drive block 4 is simultaneously connected to the guide mechanism 5 and the body 1; when the drive block 4 moves, it drives the sterile bag 3 and the guide mechanism 5 to move synchronously; the area where the zipper 6 is closed is sealed, and the sealing structure remains sealed when the drive block 4 moves.

[0024] In this embodiment, the sealing structure includes a body 1, a sterile cover 2, a sterile bag 3, a drive block 4, and a guide mechanism 5. The sterile cover 2 is equipped with a zipper 6 with an opening for mounting the guide mechanism 5. The sterile bag 3 has an opening that fits tightly against the side of the guide mechanism 5 away from the zipper 6 opening, ensuring a sufficiently small gap between the sterile cover 2 and the sterile bag 3, preventing air from entering the sealing structure. The sterile cover 2 and the sterile bag 3 form a sealed space. The body 1 and the drive block 4 are both located within the sealed structure. Within the enclosed space, the drive block 4 is simultaneously connected to both the guide mechanism 5 and the body 1, and the drive block 4 can move on the body 1. When the drive block 4 moves, it drives the sterile bag 3 and the guide mechanism 5 to move synchronously, ensuring that the drive block 4 remains inside the sterile cover 2 and the sterile bag 3. The area where the zipper 6 is closed is sealed, ensuring that bacteria cannot pass through the area where the zipper 6 is closed and enter the enclosed space. When the drive block 4 moves, the sealing structure remains sealed, ensuring that the entire interior of the sealing structure remains sterile throughout the movement of the drive block 4.

[0025] Reference Figure 3 The guide mechanism 5 includes an outer frame 51 and two connectors 52. The outer frame 51 is provided with a zipper head 53, and the connectors 52 are disposed on the opening of the zipper 6.

[0026] In this embodiment, the guiding mechanism 5 includes an outer frame 51 and two connectors 52. The outer frame 51 is provided with a zipper head 53, and the two connectors 52 are respectively located on both sides of the zipper head 53. The connectors 52 are disposed on the opening of the zipper 6. When the guiding mechanism 5 is driven to move by the driving block 4, the two zipper heads 53 are also driven by the outer frame 51 to move synchronously, so that the opening position of the zipper 6 follows the driving block 4. Since the sterile bag 3 is also located at the opening position of the zipper 6, this structure can also ensure that the sterile bag 3 moves synchronously with the driving block 4.

[0027] Reference Figure 3 The connector 52 is provided with a sliding groove 521, and the outer frame 51 can slide along the sliding groove 521.

[0028] In this embodiment, both connectors 52 have grooves 521 on their sides, and the outer frame 51 is simultaneously disposed within the grooves 521 of both connectors 52. The outer frame 51 can slide along the grooves 521, allowing the distance between the two connectors 52 to be freely adjusted by sliding the two connectors 52 relative to the outer frame 51 in some scenarios. In another embodiment, the two connectors 52 can also slide along the grooves 521, so that the two connectors 52 are directly spaced a certain distance apart. In this case, the structure and position of the sterile bag 3 and the drive block 4 near the connectors 52 can be adjusted and inspected, improving the safety and maintenance convenience of the sealing structure.

[0029] Reference Figure 4 and Figure 5 The drive block 4 is provided with an installation part 41, and the connector 52 is detachably connected to the installation part 41; the zipper head 53 is provided with a lower limit 531, and the connector 52 is provided with an upper limit 526, the upper limit 526 abutting against the installation part 41.

[0030] In this embodiment, since the mounting part 41 is located on the drive block 4, the connector 52 can be detachably connected to the mounting part 41, thus realizing the detachable connection between the connector 52 and the drive block 4. The zipper head 53 is provided with a lower limit 531 to ensure that the two connectors 52 always maintain a certain distance. The two connectors 52 are separated by the lower limit 531, and the minimum distance between the two connectors 52 during relative movement is the distance between the two lower limit 531. As the connectors 52 gradually approach the zipper head 53, the connectors 52 will eventually contact the lower limit 531. After that, the connectors 52 are blocked by the lower limit 531 and cannot get closer to the zipper head 53, ensuring that there is always a certain gap between the two connectors 52 for installing the drive block 4. At the same time, the connectors 52 are provided with an upper limit 526, which abuts against the mounting part 41. The upper limit 526 can prevent the connectors 52 from getting too far away from the zipper head 53 or even detaching from the outer frame 51. When the distance between the connectors 52 and the zipper head 53 is greater than a certain value, the upper limit 526 on the connectors 52 is blocked by the outer frame 51 to prevent the connectors 52 from detaching from the outer frame 51 and ensure the safety of the entire sealing structure.

[0031] Reference Figure 6 The connector 52 is also provided with a guide plate 522, and a groove 523 is provided between the guide plate 522 and the connector 52. The guide plate 522 is located on the outside of the sterile cover 2, and the connector 52 is located on the inside of the sterile cover 2.

[0032] In this embodiment, the connector 52 is also provided with a guide plate 522, which is in direct contact with the exterior. A groove 521 is located on the guide plate 522, and the outer frame 51 is located in the groove 521. At the same time, a groove 523 is provided between the guide plate 522 and the connector 52. The guide plate 522 is located on the outside of the sterile cover 2, and the connector 52 is located on the inside of the sterile cover 2. This structure allows the sterile cover 2 to be clamped between the guide plate 522 and the connector 52, which is beneficial for fixing the sterile cover 2.

[0033] Reference Figure 6 The guide plate 522 is provided with a buckle 524 on the side near the connector 52, and the zipper 6 is disposed between the buckle 524 and the groove 523.

[0034] In this embodiment, the guide plate 522 is provided with a buckle 524 on the side near the connector 52. The zipper 6 is disposed between the buckle 524 and the groove 523. When the zipper 6 moves away from the groove 523 by a certain distance, the position of the zipper 6 is locked by the buckle 524, preventing the sterile cover 2 connected to the zipper 6 from falling off the guide plate 522, thus ensuring the stability and effectiveness of the sealing structure.

[0035] Reference Figure 7 The outer frame 51 is also provided with an installation seam 511, the first end of the zipper head 53 is fixed in the installation seam 511, and the second end of the zipper head 53 engages with the chain teeth located on the zipper 6.

[0036] In this embodiment, the outer frame 51 is also provided with an installation seam 511. The first end of the zipper head 53 is fixed in the installation seam 511, and the second end of the zipper head 53 engages with the zipper teeth located on the zipper 6. The two ends of the zipper head 53 are respectively connected to the outer frame 51 and the zipper 6. The zipper head 53 and the outer frame 51 are fixed, the zipper head 53 and the zipper teeth of the zipper 6 are engaged, and the zipper head 53 can move along the zipper 6 with the outer frame 51.

[0037] Reference Figure 1-3 The main body of the drive block 4 is located on the side of the guide plate 522 away from the connector 52, and the opening of the sterile bag 3 is tightly fitted to the side of the connector 52 away from the main body of the drive block 4.

[0038] In this embodiment, the drive block 4 includes a main body and a mounting part 41. The main body of the drive block 4 is located on the side of the guide plate 522 away from the connector 52, that is, away from the body 1. Simultaneously, the opening of the sterile bag 3 is tightly fitted to the side of the connector 52 away from the main body of the drive block 4, ensuring that bacteria cannot enter the sealed space from the gap between the sterile bag 3 and the connector 52. In this embodiment, because the opening of the sterile bag 3 is tightly fitted to the side of the connector 52 away from the main body of the drive block 4, that is, a portion of the sterile bag 3 passes through the guide mechanism 5, the two connectors 52 on the guide mechanism 5 also have a certain clamping effect on the sterile bag 3, further stabilizing the stability of the fit between the sterile bag 3 and the connector 52.

[0039] Reference Figure 5 The guide mechanism 5 is detachably connected to the mounting portion 41 located on the drive block 4 via the connector 52.

[0040] In this embodiment, the connector 52 is located on the guide mechanism 5, and the mounting part 41 is located on the drive block 4. The connector 52 and the mounting part 41 are detachably connected, thus ensuring a detachable connection between the guide mechanism 5 and the drive block 4. In another embodiment, the drive block 4 is replaceable. Since the guide mechanism 5 and the drive block 4 are detachable, the sterile bag 3 can be installed on the guide mechanism 5 along with the drive block 4 in a sterile environment, or removed from the guide mechanism 5.

[0041] Reference Figure 7 The connector 52 is provided with a limiting groove 525, and the mounting part 41 is provided with a limiting ridge 411, which is installed in the limiting groove 525.

[0042] In this embodiment, the connector 52 is provided with a limiting groove 525, and the mounting part 41 is provided with a limiting ridge 411. The specific structures of the limiting groove 525 and the limiting ridge 411 are not limited in this application, as long as their structures cooperate to ensure that the limiting ridge 411 can be installed within the limiting groove 525. The tight fit between the limiting groove 525 and the limiting ridge 411 ensures that the drive block 4 will not detach from the guide mechanism 5 during movement. In some embodiments, the contact portion between the limiting ridge 411 and the limiting groove 525 is made of a material with a relatively high coefficient of friction to further prevent relative sliding between the limiting ridge 411 and the limiting groove 525 during the movement of the drive block 4, thereby improving the stability of the drive block 4 mounted on the guide mechanism 5.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
