[0056] As shown in FIGS. 1-8, in the embodiment of the present application, a support mechanism for an optical fiber transmission mechanism is provided, characterized by comprising a mounting structure 22, a connecting frame 2, a first adjusting structure 1 and a second adjusting structure 3. Figure 1 and Figure 2 As shown in FIGS. 1-8, in the embodiment of the present application, a support mechanism for an optical fiber transmission mechanism is provided, characterized by comprising a mounting structure 22, a connecting frame 2, a first adjusting structure 1 and a second adjusting structure 3.

[0057] The mounting structure 22 is used for mounting and supporting the fiber transmission mechanism;

[0058] The connecting frame 2 is arranged along the transverse direction of the patient platform;

[0059] The first adjusting structure 1 is arranged along the longitudinal direction of the patient platform, and is arranged to be capable of adjusting the longitudinal position of the mounting structure 22 relative to the patient platform;

[0060] The second adjusting structure 3 is arranged to be capable of adjusting the height position of the mounting structure 22 relative to the patient platform;

[0061] The connecting frame 2, the first adjusting structure 1 and the second adjusting structure 3 are sequentially connected in an interchangeable order, a first end structure of the sequential connection is used for detachably connecting to the patient platform, and the mounting structure 22 is arranged at a last end structure of the sequential connection.

[0062] In the preferred embodiment of the utility model, the first adjusting structure 1 is arranged as the first end structure, the connecting frame 2 is arranged as the last end structure, and the second adjusting structure 3 is connected between the first adjusting structure 1 and the connecting frame 2.

[0063] In other embodiments, the first end structure can be arranged as the first adjusting structure 1, the last end structure is arranged as the second adjusting structure 3, and the connecting frame 2 is connected between the first adjusting structure 1 and the second adjusting structure 3. Alternatively, the first end structure is arranged as the second adjusting structure 3, the last end structure is arranged as the connecting frame 2, and the first adjusting structure 1 is connected between the second adjusting structure 3 and the connecting frame 2.

[0064] In the embodiment of the utility model, the patient platform can be a bed body (for example, a surgical bed), or a magnetic resonance platform. The longitudinal direction is also the length direction of the patient platform, and the transverse direction is also the width direction of the patient platform. The optical fiber transmission mechanism can be stably supported at the head of the patient platform through the connecting frame 2, so that the optical fiber transmission mechanism has good stability during use. When the user uses the support device, the connecting frame 2 and the optical fiber transmission mechanism can be moved along the longitudinal direction of the patient platform through the first adjusting structure 1, so that the distance between the optical fiber transmission mechanism and the head of the patient platform is adjusted. The connecting frame 2 and the optical fiber transmission mechanism can be lifted and lowered through the second adjusting structure 3, so that the height of the optical fiber transmission mechanism relative to the patient platform is adjusted. Under the premise that the optical fiber transmission mechanism is connected to the patient platform, the support device not only enables the optical fiber transmission mechanism to adjust the distance relative to the patient platform, but also enables the optical fiber transmission mechanism to adjust the height relative to the patient platform. The optical fiber transmission mechanism can obtain a better optical fiber advancing angle to meet the surgical requirements under different conditions.

[0065] As shown in Figure 1 and Figure 3 , in the embodiment of the utility model, when the first end structure is the first adjusting structure 1, the last end structure is the connecting frame 2, and the second adjusting structure 3 is connected between the first adjusting structure 1 and the connecting frame 2, the first adjusting structure 1 is detachably mounted on the patient platform, and the second adjusting structure 3 is connected between the connecting frame 2 and the first adjusting structure 1. Specifically, the first adjusting structure 1 includes a connecting member 11 and a moving member 12; the connecting member 11 connects the patient platform and the moving member 12, and the moving member 12 is arranged to be movable along the longitudinal direction of the patient platform. The connecting member 11 and the patient platform can be fixedly connected, slidably connected along the longitudinal direction of the patient platform, temporarily fixed with the patient platform after sliding to a specified position, or rotatably connected. When the connecting member 11 is fixedly connected with the patient platform, the connecting member 11 can be fixed by screw connection, clamping or the like. When the connecting member 11 is slidably connected with the patient platform, a slide rail is arranged on the patient platform along the longitudinal direction of the patient platform, and the connecting member 11 moves along the longitudinal direction of the slide rail. When the connecting member 11 moves to a specified position, the patient platform can be temporarily fixed with the slide rail by clamping, screw connection or the like.

[0066] The following are some structural examples of the connecting member 11 and the moving member 12. The patient platform connecting member 11 can be provided as a threaded sleeve, and the moving member 12 can be provided as a threaded rod. By rotating the threaded sleeve, the threaded rod can be extended or retracted from the threaded sleeve. The connecting member 11 can also be provided as a gear, and the moving member 12 can be provided as a rack capable of engaging with the gear. By rotating the gear, the rack can be moved along the longitudinal direction of the patient platform. It should be understood that the above is only an exemplary description of the connecting member 11 and the moving member 12, and the specific structure of the two is not limited thereto.

[0067] The following is a specific implementation of the connecting member 11 and the moving member 12 in the embodiment of the utility model. The connecting member 11 comprises:

[0068] The connecting seat 111 has a through hole through which the moving member 12 passes.

[0069] The first fastener 112 is located on one side of the through hole and can extend into the through hole to apply a locking force to the moving member 12 to prevent the moving member 12 from moving.

[0070] When the distance between the fiber-optic transmission mechanism and the patient platform head needs to be adjusted, the fiber-optic transmission mechanism can be moved to the desired position by sliding the moving member 12 in the through hole, and then the first fastener 112 can be used to apply a locking force to the moving member 12 to prevent the moving member 12 from moving further, thereby ensuring that the moving member 12 has good stability during use.

[0071] Further, the moving member 12 is provided as a slide rod, the longitudinal direction of the slide rod passes through the connecting seat 111 along the longitudinal direction of the patient platform. The shape of the cross section of the slide rod is not limited, and it can be square, triangular, or irregular. The shape of the through hole is adapted to the shape of the slide rod to ensure good stability between the slide rod and the connecting seat 111. It should be noted that in the embodiment of the utility model, the cross section of the slide rod is circular to facilitate processing. Therefore, when the cross section of the slide rod is circular, two slide rods are provided to ensure stability between the slide rods and the connecting seat 111. The two slide rods are parallel to each other and pass through the connecting seat 111. It should be understood that the slide rod can also be three or more.

[0072] In the embodiment of the utility model, the first adjusting structure 1 is provided on the side of the patient platform, or can be provided on the bed surface of the patient platform or the bed bottom of the patient platform. It is suitable for different types of operating platforms, such as different manufacturers of magnetic resonance equipment.

[0073] In the embodiment of the utility model, the connecting member 11 is preferably arranged in sliding connection with the patient platform along the longitudinal direction of the patient platform, and the connecting member 11 further comprises a connecting piece 13, which is used for fixing the connecting seat 111 to a certain position beside the patient platform. Specifically, the first fastener 112 and the connecting piece 13 are both arranged as hand screws, and the first fastener 112 and the connecting piece 13 are both in threaded connection with the connecting seat 111.

[0074] When the connecting member 11 is arranged beside the patient platform, the side wall of the patient platform is fixed with a sliding rail along the longitudinal direction of the side wall, and the side of the connecting seat 111 facing the sliding rail is provided with a sliding groove 1111 (as shown in Figure 4 ) adapted to sliding with the sliding rail. Of course, as an equivalent modification, the side wall of the patient platform can be provided with a sliding groove along the longitudinal direction of the side wall, and the side of the connecting seat 111 facing the sliding rail is provided with a sliding block adapted to sliding with the sliding groove.

[0075] When the connecting member 11 is arranged on the bed surface of the patient platform, the bed surface of the patient platform is provided with a groove along the longitudinal direction of the bed surface, and the bottom of the connecting seat 111 is fixed with a guide block 1112 located in the groove and adapted to sliding with the groove (as shown in Figure 5 ).

[0076] When the connecting member 11 needs to be used, the connecting seat 111 is first slid along the sliding rail to a suitable position, and then the connecting piece 13 is tightened to fix the connecting seat 111 to the patient platform. When the support mechanism needs to be disassembled, the connecting seat 111 can be slid away from the sliding rail or the guide rail. It can be understood that the above is only an exemplary description of the structure of the connecting seat 111, and is not limiting.

[0077] When the slide rod needs to be fixed, the user only needs to rotate the first fastener 112 to make the end of the first fastener 112 extend into the through hole to exert a locking force on the side wall of the slide rod, so that the slide rod cannot move through the friction between the first fastener 112 and the slide rod. By reversely rotating the first fastener 112, the locking of the slide rod is released, and the slide rod can continue to slide along the longitudinal direction of the patient platform. The operation is simple and convenient, and provides convenience for the user to adjust the optical fiber transmission mechanism in the horizontal direction.

[0078] When the device needs to be connected to the patient platform, the connecting piece 13 is only needed to be rotated to abut against the sliding rail or the groove after passing through the connecting seat 111. If the device needs to be disassembled, the connecting piece 13 is only needed to be reversely rotated. Thus, the effect of conveniently installing and disassembling the device for the user is achieved.

[0079] As shown in Figure 2 and Figure 6As shown, in the embodiment of the utility model, for the second adjustment structure 3 can set up as the cylinder, the hydraulic cylinder, the screw sleeve screw structure. It is worth noting that, above is only the second adjustment structure 3 exemplary explanation, and is not limited to this.

[0081] When the height of connecting frame 2 and fiber transmission mechanism needs to be adjusted, the user drives connecting frame 2 and fiber transmission mechanism to rise or fall together through swing height adjustment member 31, thereby realizing the height adjustment of fiber transmission mechanism, and swing member 31 also makes certain adjustment to the pitch angle of fiber transmission mechanism when adjusting the height of fiber transmission mechanism, and the fiber transmission mechanism can have better angle to push the fiber. When the fiber transmission mechanism is adjusted to the appropriate position, the user can lock swing height adjustment member 31 through locking member 32, so that it cannot continue to rotate, thereby providing good stability for the fiber transmission mechanism in the use process.

[0082] In the embodiment of the utility model, swing height adjustment member 3 includes fixed seat 311, swing rod 312 and support rod 313, fixed seat 311 is fixedly connected with mobile member 12, first end of swing rod 312 is hinged with first hinge point of fixed seat 311, second end of swing rod 312 is used to connect connecting frame 2, first end of support rod 313 is hinged with second hinge point of fixed seat 311, second end of support rod 313 is slidably connected to swing rod 312 through sliding block.

[0085] Second fastener 322 can pass through the side wall of sliding block 321 to apply locking force to swing rod 312, so that sliding block 321 is relatively fixed with swing rod 312.

[0086] Specifically, the hinged point of the swing rod 312 and the fixed seat 311 is located above the hinged point of the support rod 313 and the fixed seat 311, so that the fixed seat 311, the swing rod 312 and the support rod 313 form a triangular structure, which can have good stability. In order to facilitate the processing of the slide rod, while ensuring that the slide block 321 and the swing rod 312 cannot rotate relative to each other, the cross section of the swing rod 312 is circular and the swing rod 312 is provided as two, and the two swing rods 312 are parallel to each other. Both swing rods 312 pass through the slide block 321. Of course, this is not restrictive, the cross section of the swing rod 312 can also be triangular, square or special-shaped, and the stability between the swing rod 312 and the slide block 321 is provided by the non-circular cross section. It can be understood that the slide rod can also be three or more.

[0087] The second fastener 322 is provided as a hand screw and is threadedly connected with the slide block 321. By rotating the second fastener 322, the slide block 321 can be locked and unlocked through the friction between the second fastener 322 and the side wall of the swing rod 313.

The second fastener 322 is installed on the telescopic rod for preventing the mutual sliding of the plurality of rod bodies.

[0089] As shown in Figure 2 and Figure 7 In the embodiment of the utility model, the connecting frame 2 includes an adjusting rail 21 arranged transversely to the patient platform and a mounting structure 22 arranged on the adjusting rail 21 for mounting the optical fiber transmission mechanism, and the mounting structure 22 can be adjusted in position on the patient platform in the transverse direction along the adjusting rail 21.
