Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a quick-release and quick-installation device for an optical fiber transmission mechanism and an optical fiber transmission system. Background Technology
[0002] When using LITT (Limited Invasive Therapy) surgery, a detailed surgical plan is required. Guided by a stereotactic device, an optical fiber is placed intracranially. The patient is then transferred to an MRI scanner for real-time guidance and monitoring. A fiber optic drive mechanism controls the precise movement of the inserted fiber, achieving accurate ablation. This mechanism needs to be fixed to a device connected to the operating table (e.g., a bed frame). Therefore, the fiber optic drive mechanism and bed frame must be designed for quick assembly and disassembly, facilitating the surgeon's operation, reducing installation time, and expediting the surgical process. Summary of the Invention
[0003] The purpose of this utility model is to provide a quick-release and quick-installation device and structure for fiber optic transmission mechanisms, so as to achieve the effect of quick disassembly and assembly of fiber optic transmission mechanisms.
[0004] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0005] According to a first aspect of the present invention, a quick-release and quick-installation device for an optical fiber transmission mechanism is provided, comprising:
[0006] The base has a sliding connection portion extending along a first direction. The sliding connection portion is configured to allow the mating portion of the optical fiber transmission mechanism to slide into the first direction and to limit the mating portion in a second direction after the mating portion slides in. The second direction is perpendicular to the bottom surface of the sliding connection portion where the first direction is located.
[0007] A movable limiting mechanism is disposed on the base. The movable limiting mechanism has a limiting position and an unlocking position. In the limiting position, the movable limiting mechanism limits the mating part that slides into the sliding connection part in the first direction. In the unlocking position, the mating part is adapted to slide out of the sliding connection part along the first direction.
[0008] In an exemplary embodiment of the present invention, the sliding connection portion is configured as a groove.
[0009] In an exemplary embodiment of this utility model, the movable limiting mechanism is located below the bottom surface of the slide groove. The movable limiting mechanism includes a locking part and an operating part. The locking part is connected to the operating part, and the operating part is driven to switch the locking part between the limiting position and the unlocking position. In the limiting position, the locking part extends from the bottom surface of the slide groove into the interior of the slide groove and forms a locking with the mating part. In the unlocking position, the locking part retracts to below the bottom surface of the slide groove.
[0010] In an exemplary embodiment of this utility model, the movable limiting mechanism further includes a biasing member. At the limiting position, the biasing member applies a biasing force to the locking part to make the locking part lock with the mating part. By driving the operating part, the biasing force can be overcome so that the biasing member drives the locking part to switch to the unlocking position.
[0011] In an exemplary embodiment of the present invention, the biasing member is a spring, the snap-fit portion is disposed on the upper surface of the spring, and the operating portion is disposed at the other end of the spring.
[0012] In an exemplary embodiment of this utility model, a limiting block is provided at the far end of the base in the sliding direction of the slide groove, a guide slope is provided on the side of the locking part facing the slide groove inlet, and a locking surface is provided on the side facing away from the slide groove inlet, and the mating part is locked between the limiting block and the locking surface.
[0013] In an exemplary embodiment of this utility model, the base has an internal mounting cavity, the spring is installed in the mounting cavity, the mounting cavity extends through the lower surface of the base, and a base plate is provided on the lower surface of the base to cover the mounting cavity. The base plate and the base are detachably connected.
[0014] In an exemplary embodiment of this utility model, the base is fixedly provided with a connecting column in the mounting cavity, and the portion of the spring located in the mounting cavity is provided with a through hole, through which the spring is fitted onto the connecting column.
[0015] In an exemplary embodiment of the present invention, the connecting column penetrates the base plate and extends below the base plate, and the circumferential sidewall of the connecting column below the base plate is machined with a threaded structure for threaded connection with the bed frame.
[0016] According to a second aspect of this utility model, a quick-release and quick-install structure for an optical fiber transmission mechanism is provided, comprising a quick-release and quick-install device for an optical fiber transmission mechanism as described in any one of the above claims and an optical fiber transmission mechanism. The optical fiber transmission mechanism is capable of adjusting the optical fiber forward and backward and / or rotating it. A mating part is provided at the bottom of the optical fiber transmission mechanism, enabling quick assembly and disassembly through the mating part and the quick-release and quick-install device. The connection method between the bottom of the optical fiber transmission mechanism and the mating part can be any one of fixed connection, detachable connection, or integral molding. Exemplary embodiments of this utility model may have some or all of the following beneficial effects:
[0017] In the quick-release and quick-installation device for a fiber optic transmission mechanism provided in this exemplary embodiment, the fiber optic transmission mechanism is slidably connected to the sliding connection on the base along a first direction through the mating part of the fiber optic transmission mechanism, allowing the fiber optic transmission mechanism to move precisely to the desired position. Once the fiber optic transmission mechanism has moved to the desired position, the movable limiting mechanism is moved to the limiting position, causing the movable limiting mechanism to engage with the mating part, thereby achieving the installation and fixation of the fiber optic transmission mechanism. When it is necessary to disassemble the fiber optic transmission mechanism, simply move the movable limiting mechanism from the limiting position to the unlocking position, and the fiber optic transmission mechanism can slide gently out from the sliding connection along the first direction, completing the disassembly. This structure simplifies and facilitates the disassembly and assembly of the fiber optic transmission mechanism, achieving rapid disassembly and assembly, effectively shortening operation time, providing great convenience for doctors, and accelerating the surgical process.

Example 1
[0030] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, a quick-release and quick-installation device for an optical fiber transmission mechanism is provided, comprising:
[0031] The base 1 is used to be installed on the support structure and is provided with a sliding connection part extending in a first direction. The sliding connection part is configured to be suitable for the mating part 51 of the optical fiber transmission mechanism 5 to slide into in the first direction and to limit the mating part 51 in a second direction after the mating part 51 slides in. The second direction is perpendicular to the bottom surface of the sliding connection part where the first direction is located.
[0032] An active limiting mechanism 2 is disposed on the base 1. The active limiting mechanism 2 has a limiting position and an unlocking position. In the limiting position, the active limiting mechanism 2 limits the mating part 51 that slides into the sliding connection part in the first direction. In the unlocking position, the mating part 51 is adapted to slide out of the sliding connection part along the first direction.
[0033] In this embodiment of the invention, the support structure can be configured as a bed frame installed on one side of the bed, but is not limited thereto. The sliding connection is disposed on the upper surface of the base 1, and the specific structure of the sliding connection is not specifically limited in this invention. The sliding connection can be either a slide rail structure or a slide track structure. When the sliding connection is configured as a slide rail structure, the cross-section of the slide rail can be configured as a T-shaped structure, an inverted trapezoidal structure, or an irregular shape structure; when the sliding connection is configured as a slide track, the cross-section of the slide track can be configured as an inverted T-shaped structure, a dovetail groove structure, or an irregular shape structure. Of course, the cross-sectional shapes mentioned above are only illustrative examples, and there are infinite possibilities in actual applications. Importantly, regardless of the structure adopted, the core element of the sliding connection is to effectively restrict the movement of the fiber optic transmission mechanism 5 in directions other than the first direction, ensuring the stability of the fiber optic structure after installation.
[0034] In this embodiment of the invention, the specific shape of the movable limiting mechanism 2 is not limited; for example, its shape can be trapezoidal, wedge-shaped, square, etc. When the mating part 51 slides into the sliding connecting part, the movable limiting mechanism 2 can be pressed to the unlocked position by the bottom surface of the mating part 51, or it can be moved to the unlocked position manually by the user. When the mating part 51 slides to the expected position, the movable limiting mechanism 2 can either automatically move to the limiting position to form a locking engagement with the mating part 51, or it can be moved to the limiting position manually.
[0035] Furthermore, when the fiber optic transmission mechanism 5 moves to the predetermined position along the sliding connection via the mating part 51, the movable limiting mechanism 2 only needs to be moved to the limiting position to engage with the mating part 51, preventing further movement of the fiber optic transmission mechanism 5 along the sliding connection, thus achieving a stable installation and fixation between the fiber optic transmission mechanism 5 and the base 1. When it is necessary to disassemble the fiber optic transmission mechanism 5, simply retract the movable limiting mechanism 2 from the limiting position to the unlocked position, and the fiber optic transmission mechanism 5 can slide along the sliding connection, thereby achieving disassembly. Through the above structure, the fiber optic transmission mechanism 5 can be quickly disassembled and assembled, effectively shortening the operation time, providing great convenience for doctors, and also accelerating the surgical process.
[0036] In this embodiment of the invention, the sliding connection is configured as a sliding groove 11. Specifically, two parallel guide plates are fixed on the upper surface of the base 1 along a first direction. Guide grooves are chiseled on opposite sides of the two guide plates along the first direction. A limiting plate covers the guide plates, and the sliding groove 11 is formed between the two guide grooves. This structure not only achieves stable fixation of both sides of the mating part 51, but also improves the stability of the fiber optic transmission mechanism 5 during sliding and fixing with the base 1. Furthermore, the sealing plate effectively constrains the upper surface of the mating part 51, ensuring that the mating part 51 will not separate from the base 1, thereby improving the stability of the fiber optic transmission mechanism 5 during use.
[0037] like Figure 1 and Figure 3 As shown in this embodiment of the present invention, the base 1 has a cavity at the location of the movable limiting mechanism 2, and the cavity is connected to the slide groove 11. The movable limiting mechanism 2 is located below the bottom surface of the slide groove 11 (i.e., inside the cavity). The movable limiting mechanism 2 can be set between two guide grooves, or in any one of the guide grooves, or in both guide grooves respectively. In this present invention, it is preferable to set the movable limiting mechanism 2 in one of the guide grooves, which not only saves the space of the base 1, but also reduces the manufacturing cost of the device.
[0038] In this embodiment of the invention, the movable limiting mechanism 2 includes a locking part 21 and an operating part 22. The locking part 21 is connected to the operating part 22, and the locking part 21 can be switched between a limiting position and an unlocking position via the driving part and the operating part 22. Specifically, the limiting position is located above the slide groove 11, while the unlocking position is located below the bottom of the slide groove 11. When it is necessary to fix the fiber optic transmission mechanism 5, it is only necessary to move the locking part 21 from the bottom of the slide groove 11 to the inside of the slide groove 11, so that the locking part 21 is in the limiting position, thereby realizing the locking of the locking part 21 and the mating part 51. The locking part 21 can be moved to the limiting position by the movable limiting structure 2 itself, or it can be moved to the limiting position by manual operation, without limitation. When it is necessary to disassemble the fiber optic transmission mechanism 5, simply apply force to the operating part 22. The movement of the operating part 22 will drive the locking part 21 to move, so that the locking part 21 returns to the unlocked position below the bottom of the slide groove 11. Then the fiber optic transmission mechanism 5 can be slid to separate the mating part 51 from the base 1, thereby realizing the disassembly of the fiber optic transmission mechanism 5 from the base 1.
[0039] In a further optimization of this invention, the movable limiting mechanism 2 also includes a biasing member 23. The biasing force applied to the locking part 21 by the biasing member 23 ensures that the locking part 21 can automatically move upward to the limiting position and remain stably in the limiting position, thereby forming the required tight locking state with the mating part 51, achieving stable fixation of the fiber optic transmission mechanism 5. Specifically, when a force is applied to the locking part 21 or the operating part 22, and this force overcomes the biasing force provided by the biasing member 23, the locking part 21 can be moved from the limiting position to the unlocking position, allowing the mating part 51 to continue sliding along the slide groove 11. Once the force is removed, the biasing force can cause the locking part 21 to return to the limiting position. By applying a biasing force to the locking part 21 by the biasing member 23, the locking part 21 can re-establish a stable connection with the mating part 51, ensuring good stability of the fiber optic transmission mechanism 5 in the fixed state.
[0040] Furthermore, the biasing member 23 is configured as a spring, which is embedded inside the base 1. The locking part 21 is located on the upper surface of the spring, and one end of the spring extends out from inside the base 1. The end of the spring on the outside of the base 1 is configured as the operating part 22. When the user presses the operating part 22, the spring deforms, thereby moving the locking part 21 to the unlocked position below the bottom of the slide groove 11. When the spring is not pressed and the locking part 21 is aligned with the mating part 51, the spring returns to its original shape, thus engaging the locking part 21 with the mating part 51. Of course, the structure of the biasing member 23 is not limited to a spring. For example, a combination of a connecting plate and an elastic member can be used, where the locking part 21 is located on the upper surface of the connecting plate, and the operating part 22 is located at one end of the connecting plate. The elastic member can be a torsion spring, a spring, or other structures.
[0041] In this embodiment of the invention, one end of the slide groove 11 is configured as the groove inlet. The mating part 51 can only slide into the slide groove 11 from the groove inlet end. The locking part 21 is configured with a guide inclined surface facing the groove inlet. Specifically, the guide inclined surface is gradually inclined from top to bottom towards the groove inlet. When the mating part 51 slides into the slide groove 11, the mating part 51 will gradually apply pressure along the guide inclined surface of the locking part 21, causing the locking part 21 to automatically retract to the unlocked position, thereby ensuring that the mating part 51 can slide smoothly and without obstruction along the slide groove 11. The sliding process of the mating part 51 in the slide groove 11 can automatically press the locking part 21 to the unlocked position. The user only needs to focus on the movement operation of the fiber optic transmission mechanism 5 and the mating part 51, without any additional steps, which greatly simplifies the installation process of the fiber optic transmission mechanism 5.
[0042] Furthermore, the snap-fit part 21 is configured as a snap-fit surface on the side opposite to the guide inclined surface, and a limiting block 12 is fixed on the upper surface of the base 1. The limiting block 12 is located at the end of the slide groove 11 away from the groove inlet. When the side wall of the mating part 51 abuts against the limiting block 12, the snap-fit part 21 is precisely aligned with the mating part 51. Under the elastic action of the spring, the snap-fit part 21 and the mating part 51 complete the snap-fit engagement, thereby snapping the mating part 51 between the snap-fit surface and the limiting block 12. The limiting block 12 acts as a blocking force on the mating part 51, preventing the mating part 51 from continuing to slide along the slide groove 11 after abutting against the limiting block 12, thereby improving the stability of the fiber optic transmission mechanism 5 during use.
[0043] In this embodiment of the utility model, the base plate 3 is provided with a connecting structure for connecting with the supporting structure. Specifically, the base 1 has an internal mounting cavity 13, and the connecting structure is a connecting post 4. The connecting post 4 is fixedly connected to the inner top wall of the base 1 in the mounting cavity 13. The mounting cavity 13 penetrates the lower surface of the base 1. The end of the spring away from the operating part 22 has a through hole. The end of the spring away from the operating part 22 is inserted into the mounting cavity 13 from below the base 1, and the connecting post 4 passes through the through hole. The connecting post 4 plays a positioning role for the spring in the through hole, thereby realizing the positioning and fixing of the spring and ensuring good stability of the spring during use.
[0044] Furthermore, a base plate 3 is provided below the base 1. The base plate 3 is used to cover the mounting cavity 13. The base plate 3 is connected to the base 1 by threaded nails. Of course, the connection method between the base plate 3 and the base 1 is not limited to this. It can also be connected and fixed by magnetic attraction, snap-fit, locking, welding, or pasting.
[0045] In this embodiment of the utility model, the connecting post 4 penetrates the base plate 3 and extends to the bottom of the base plate 3. The part of the connecting post 4 located below the base plate 3 is used to connect with the bed frame. The connecting post 4 can be connected to the bed frame by welding, plugging, threaded connection, snap-fit, etc. In this utility model, the connecting post 4 has a threaded connection processed on the circumferential side wall of the part below the base plate 3. The connecting post 4 is connected to the bed frame by the threaded connection, which not only ensures the tight fixation between the base 1 and the bed frame and guarantees the stability and reliability of the overall structure, but also provides great convenience for users, making the disassembly and installation of the base 1 easy and quick. Example 2
[0046] like Figure 3 and Figure 4 As shown in the present invention, a quick-release and quick-install structure for an optical fiber transmission mechanism is provided, including any of the quick-release and quick-install devices for an optical fiber transmission mechanism described in Embodiment 1. The quick-release and quick-install structure for an optical fiber transmission mechanism further includes an optical fiber transmission mechanism 5, which can adjust the optical fiber forward and backward and rotate. The bottom of the optical fiber transmission mechanism 5 is provided with a mating part 51 that can form a snap-fit with the snap-fit part 21. Quick disassembly and assembly are achieved through the mating part 51 and the quick-release and quick-install device for the optical fiber transmission mechanism. The connection method between the bottom of the optical fiber transmission mechanism 5 and the mating part 51 can be set to any one of fixed connection, detachable connection, or integral molding.
[0047] Reference Figure 4 and Figure 5 The lower surface of the mating part 51 is provided with a slot 511 for engaging with the snap-fit part 21. The fiber optic transmission mechanism 5 can precisely realize the longitudinal displacement and / or rotational movement of the ablation fiber.
