Description

Technical Field

[0001] This utility model relates to the field of laser therapy equipment technology, and in particular to an optical fiber interface device and a laser device. Background Technology

[0002] In existing technologies, fiber optic interface protection for medical laser equipment primarily relies on manually operated mechanical protective covers. After the fiber optic connector is removed, the operator must rotate or slide the metal / plastic protective cover to close the laser window. However, this solution suffers from a high degree of reliance on human intervention. In emergency clinical scenarios or under high-intensity work conditions, medical personnel may easily forget to close the protective cover, allowing dust, liquids, and other contaminants to enter the laser's internal optical path system. Furthermore, the inefficiency of manual operation is particularly pronounced in surgical procedures that require repeated fiber optic insertion and removal, significantly extending treatment preparation time.

[0003] To mitigate the drawbacks of manual operation, some laser devices employ a spring-return protective door design, which uses a pre-compressed spring to automatically close the door when the fiber is pulled out. However, this solution suffers from insufficient sealing reliability in medical settings, making it difficult to consistently achieve the required protection level and sealing effect for medical equipment. Furthermore, the mechanical structures such as the slide rails and hinges of the spring-driven assembly are prone to accumulating debris after repeated operation, potentially creating a source of contamination inside the equipment.

[0004] Based on the above, there is an urgent need for a fiber optic interface device and a laser device to solve the aforementioned technical problems. Utility Model Content

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] The following is based on the appendix Figure 1 To be continued Figure 6 This invention introduces the fiber optic interface device and laser equipment provided by this utility model.

[0044] like Figure 1 , Figure 2As shown, in this embodiment, the laser device mainly includes a housing 100, a laser generator 200, and a fiber optic interface device. The housing 100 has a mounting slot and an internal accommodating space, with the mounting slot and accommodating space communicating with each other. The laser generator 200 is fixedly mounted within the accommodating space, and the fiber optic interface device is fixedly mounted at the mounting slot and connected to the laser generator 200 by bolts. The fiber optic interface device has a fiber optic port 11, through which the laser fiber to be connected can be inserted into the housing 100 and connected to the connector 2001 of the laser generator 200, thereby transmitting the laser light to the outside of the housing 100 via the laser fiber.

[0045] Specifically, such as Figure 3 , Figure 4 As shown, the fiber optic interface device includes an interface board 1, a baffle 2, a drive element 3, a control element 4, and a clamping element 5. The interface board 1 is fixedly connected to the device housing 100 (or the laser generator 200), and the drive element 3 and the clamping element 5 are also fixed in place. When the interface board 1 is installed on the device housing 100, it covers the mounting slot, and the interface board 1 is provided with the aforementioned fiber optic port 11 for the laser fiber to pass through.

[0046] The driving component 3 is fixedly connected to the interface plate 1 by bolts. The baffle 2 is located on the side of the interface plate 1 facing the laser generator 200 and is connected to the driving component 3 for transmission. The driving component 3 uses a motor, electromagnet, etc., and can drive the baffle 2 to move between a first position and a second position. Figure 4 As shown, when the baffle 2 moves to the first position, it blocks the optical fiber access port 11, preventing the laser optical fiber from extending into the device housing 100 through the port 11. When the baffle 2 moves to the second position, as... Figure 5 As shown, the baffle 2 can open the optical fiber through port 11, at which time the laser optical fiber can extend into the device housing 100 through the optical fiber through port 11 and connect to the laser generator 200.

[0047] The control element 4 is fixedly mounted on the drive element 3 and is signal-connected to the drive element 3. The control element 4 includes an optical fiber sensor capable of sensing the laser optical fiber. For example, the laser optical fiber is equipped with a coil. When the coil moves to a certain distance from the control element 4, the control element 4 can detect the approach of the laser optical fiber using electromagnetic principles such as mutual inductance, and send a first signal to the drive element 3, causing the drive element 3 to move the baffle 2 to a second position. Furthermore, when the control element 4 senses that the coil has moved to a certain distance from the control element 4, it can detect the departure of the laser optical fiber using a similar principle, and send a second signal to the drive element 3, causing the drive element 3 to move the baffle 2 to a first position. In other words, when the operator moves the laser optical fiber in a direction approaching the laser device, the optical fiber port 11 is automatically opened by the baffle 2, facilitating the insertion of the laser optical fiber. And when the operator pulls out the laser optical fiber and moves away from the laser device, the optical fiber port 11 is automatically blocked by the baffle 2.

[0048] The clamping member 5 is fixedly disposed within the equipment housing 100, and at least a portion of the clamping member 5 is spaced apart from the laser generator 200. When the baffle 2 moves to the first position, the clamping member 5 applies pressure to the baffle 2 toward the laser generator 200, thereby causing the clamping member 5, the baffle 2, and the laser generator 200 to abut against each other in sequence, improving the sealing performance of the baffle 2 to the insertion interface 2001.

[0049] In use, based on the distance between the laser fiber and the control element 4, the drive unit 3 can automatically move the baffle 2 between a first position and a second position, thereby switching the fiber through the port 11 between a blocked state and an open state. This maintains the seal while facilitating the connection of the laser fiber. Simultaneously, the clamping element 5 further enhances the seal in the blocked state, preventing the entry of external foreign objects.

[0050] Specifically, such as Figures 3 to 5 As shown, in this embodiment, the optical fiber is arranged along the axial direction of the port 11 and the insertion interface 2001 in a preset first direction. The interface plate 1 and the baffle 2 are both arranged parallel to a preset second direction, and the preset second direction is perpendicular to the preset first direction. The clamping member 5 is a spring, one end of which is welded and fixed to the interface plate 1, and the other end is spaced apart from the interface plate 1. When the baffle 2 reaches the first position, the other end of the spring can press the baffle 2 against the laser generator 200, so that the other end of the spring, the baffle 2 and the laser generator 200 abut against each other in sequence, thereby enhancing the sealing of the laser equipment.

[0051] Preferably, in this embodiment, the reed has a U-shaped structure, and the axes of the optical fiber through the port 11 and the insertion interface 2001 both pass through the middle space of the U-shaped structure. When the baffle 2 reaches the first position, the two ends of the U-shaped structure can respectively abut against the two side edges of the baffle 2, thereby pressing the baffle 2 parallel to the laser generator 200, further ensuring the reliability of the sealing. Preferably, the ends of the U-shaped structure are bent in a direction close to the interface plate 1 to form a guiding arc surface for guiding the baffle 2, which facilitates the baffle 2 to directly enter the space between the reed and the laser generator 200 during its movement to the first position, and causes the reed to deform.

[0052] Of course, in some embodiments, a spring can also be used to press the baffle 2 against the interface plate 1, thereby achieving a good seal for the optical fiber port 11. Exemplarily, in some embodiments, the end of the spring and the interface plate 1 can be spaced apart, so that when the baffle 2 moves to the first position, it enters between the spring and the interface plate 1, causing the spring to deform. At this time, the spring will press the baffle 2 against the interface plate 1, thereby sealing the optical fiber port 11 and improving the sealing performance of the laser equipment.

[0053] Optionally, in some embodiments, the clamping member 5 further includes an O-ring, which is coaxially arranged with the optical fiber port 11 and disposed between the baffle 2 and the interface plate 1. When the baffle 2 is in the first position, the O-ring abuts against the baffle 2 along a preset first direction, pressing the baffle 2 against the laser generator 200, which can also improve the sealing effect of the connector 2001. Of course, in some other embodiments, the O-ring can also be disposed between the baffle 2 and the laser generator 200, thereby improving the sealing effect of the optical fiber port 11.

[0054] It should be noted that compared to O-rings, springs are smoother, have less friction and greater deformation, which makes the movement of the baffle smoother and its service life longer. Compared to springs, O-rings provide pressure while also providing a better sealing effect.

[0055] refer to Figures 3 to 5 As shown, in this embodiment, the driving component 3 is connected to the end of the baffle 2 away from the pressing component 5, and can drive the baffle 2 to slide along a preset second direction, thereby moving the baffle 2 between a first position and a second position. Optionally, the driving component 3 may be a motor or other driving component 3, and is connected to the control element 4 via a signal connection.

[0056] Preferably, in this embodiment, the driving element 3 is an electromagnet, and under the control of the control element 4, it can move the baffle 2 to the second position, thereby automatically opening the baffle 2. Simultaneously, the fiber optic interface device also includes a reset elastic element 7, which is a spring. The spring is connected to the electromagnet and is driven to the baffle 2, causing the baffle 2 to tend to move towards the first position. For example, as... Figure 4 , Figure 5 As shown, when the baffle 2 moves from the first position to the second position, the spring is compressed and generates a spring force. This spring force causes the baffle 2 to tend to move towards the first position, so that after the electromagnet is de-energized, the baffle 2 automatically moves towards the first position.

[0057] Using an electromagnet greatly simplifies the structure of the drive component 3, reduces costs, and eliminates the need for high precision fitting, facilitating assembly. The reset elastic component 7 not only provides power for the automatic closing of the baffle 2, but also ensures that the baffle 2 remains in the first position during power outages, thus maintaining the airtightness of the laser equipment in abnormal situations.

[0058] More preferably, the output end of the electromagnet and the baffle 2 are connected by a cylindrical pin 6, so that the two can rotate relative to each other, thereby further improving the smoothness of the baffle 2 when it moves along the preset second direction and reducing jamming and other phenomena.

[0059] like Figure 6 As shown, in this embodiment, the interface plate 1 has a recessed groove 12 on the side facing the baffle 2. At least a portion of the baffle 2 is embedded in the recessed groove 12 and slides along the recessed groove 12 under the action of the driving member 3. The recessed groove 12 can guide the baffle 2, thereby further improving the smoothness when moving along the preset second direction and reducing phenomena such as jamming.

[0060] Optionally, in some other embodiments, the baffle 2 can also be rotated in a direction parallel to the interface plate 1 to open and close the optical fiber port 11. In this case, the driving component 3 can be a swing motor, or the linear motion of the electromagnet can be converted into rotation through a transmission assembly to achieve the rotation of the baffle 2. Therefore, in this embodiment, the specific movement form of the baffle 2 is not limited, as long as it can achieve the blocking and opening of the optical fiber port 11.

[0061] This utility model also provides a laser device, including a device housing 100, a laser generator 200, and the aforementioned fiber optic interface device. The fiber optic interface device is installed in the device housing 100, and an accommodating space is defined within the device housing 100. The laser generator 200 is fixedly disposed within the accommodating space. In use, based on the distance between the laser fiber and the control element 4, the drive component 3 can automatically move the baffle 2 between a first position and a second position, thereby switching the fiber optic cable through the port 11 between a blocked state and an open state. This maintains the seal while facilitating the connection of the laser fiber. Simultaneously, the clamping component 5 can press the baffle 2 against the interface plate 1 or the laser generator 200 in the blocked state, further improving the seal and preventing the entry of external foreign objects.
