[0002] The light guide arm is an important structure of the phototherapy device, which is mainly used for guiding light and changing the light path propagation path. In actual treatment, in order to meet the treatment needs of different positions and improve the convenience of operation, the light guide arm is usually connected with the base in a swing mode, so as to adjust the position of the light guide arm. At the same time, a limiting piece is arranged between the base and the light guide arm, and the swing angle range of the light guide arm relative to the base is limited, so as to prevent the light guide arm from colliding with other structures of the device due to the too large swing amplitude.

[0050] The utility model provides a light guide arm.

[0051] In combination Figures 1 to 3 As shown in the utility model, in an embodiment of the utility model, the light guide arm comprises a base 1 with a first axial direction a, a light guide arm body 2 with a second axial direction b and a limiting assembly 3 with a third axial direction c; one end of the light guide arm body 2 is a connecting end, and the light guide arm body 2 is swing-connected with the base 1 around a rotation shaft d with the connecting end as a fulcrum; the limiting assembly 3 is fixed at one end of the light guide arm body 2 close to the base 1. The limiting assembly 3 has a working position and a storage position; when the limiting assembly 3 is in the working position, the limiting assembly 3 limits the swing angle range of the light guide arm body 2, and the critical angle of the swing angle range is the angle when the first axial direction a intersects with the third axial direction c; when the limiting assembly 3 is in the storage position, the limiting assembly 3 removes the limitation on the swing angle range of the light guide arm body 2, so that the light guide arm body 2 rotates to the second axial direction b parallel to the first axial direction a.

[0052] In the embodiment, the light guide arm body 2 is internally provided with a light path propagation cavity, and a plurality of reflecting sheets are arranged in the light path propagation cavity, and the propagation path of the light is guided and changed through the plurality of reflecting sheets. When treating, medical staff needs to hold and drive the end of the light guide arm body 2 away from the base 1 to move, so as to conduct the laser to the treatment site on the skin of the patient, so as to meet the treatment needs of different positions. Therefore, the light guide arm body 2 and the base 1 are swing connected, one end of the base 1 is installed on the equipment body and is used to support the light guide arm body 2. The other end of the base 1 is swing connected with the connecting end of the light guide arm body 2. Specifically, the base 1 and the connecting end can be swing connected through a hinged structure, a rotating shaft structure or a bearing structure. The light guide arm body 2 swings around the base with the rotating shaft 2 as the axis.

[0053] For example Figure 1 As shown, the light guide arm body 2 includes a plurality of sequentially connected arm bodies, and each arm body is movably connected with each other. According to the medical staff moving the end of the light guide arm body 2 away from the base, each arm body is flexibly rotated to adjust the light path of the laser and finally conduct the laser along the end of the light guide arm body 2 away from the base 1 to the corresponding treatment site. The extension direction of the connecting end is perpendicular to the arm body connected therewith, and the end of the base 1 is bent and connected with the connecting end. At this time, the rotating shaft is arranged between the connecting end and the bent end of the base 1, so that the light guide arm body 2 swings around the base 1 with the connecting end as the fulcrum.

[0054] Referring to Figure 1 and Figure 2 , the base 2 is in a columnar structure and has a first axial direction a. The light guide arm body 2 is formed by a plurality of arm bodies and a plurality of joints in series. The arm body closest to the base 2 is in a columnar structure and has a second axial direction b. The limiting assembly 3 has a long strip-shaped structure member for limiting, which has a third axial direction c. When the light guide arm body 2 rotates around the base 1, the axis of the center is the rotating shaft d. As Figure 1In the shown state, the limiting assembly 2 is in the working position. When the light guide arm body 2 rotates clockwise, the limiting assembly 3 rotates with the light guide arm body 2, and the limiting assembly 3 can abut against the base 1, so that the light guide arm body cannot continue to rotate clockwise. At this time, the third axial direction c intersects the first axial direction a, and the limiting assembly 3 has the function of limiting the swing angle range of the light guide arm body 2 relative to the base 1. Regarding the working position, in a preferred embodiment, the third axial direction c is parallel to the rotation shaft d when the limiting assembly 2 is in the working position; in some other embodiments, the third axial direction c intersects the rotation shaft d, but when the light guide arm body 2 swings within its swingable angle range, it can drive the limiting assembly 2 to swing to the state of abutting against the base 1 and cannot continue to swing the light guide arm body 2. At this time, the limiting assembly 2 can still be defined as being in the working position. In addition, it should be noted that the default axial direction is the direction along the length of the main body and penetrating the center of the cross section. Since the base 3 and the limiting assembly 3 have a certain volume, the third axial direction c and the first axial direction a will not be in the same plane and will not intersect. If the volume of the base 3 and the limiting assembly 3 is ignored, the third axial direction c and the first axial direction a will intersect.

[0055] Then, if the light guide arm is to be stored, since the axial directions of the light guide arm body 2 and the base 1 are not parallel, a longitudinal space that can accommodate the first axial direction a and the second axial direction b vertically is needed to store the light guide arm. Referring again to Figure 2 At this time, the limiting assembly 3 is moved to the storage position, and the third axial direction c is parallel to the second axial direction b at this time, which eliminates the limitation of the swing angle range of the light guide arm body 2 relative to the base 1, and moves the light guide arm body 2 to the second axial direction b and the first axial direction a parallel, so that the longitudinal height of the light guide arm is reduced, so that a higher longitudinal space is not needed when the light guide arm is stored. In some other embodiments, the above-mentioned storage position can also be that the third axial direction c and the second axial direction b are approximately parallel, which does not affect the movement of the light guide arm body 2 to the second axial direction b and the first axial direction a parallel. At the same time, in combination with Figure 1 and Figure 2 Referring to the drawings, the base and the light guide arm body can be swung to the same side of the rotation shaft d, so that the overall length is shorter, and the transverse space in the length direction can also be saved.

[0056] In some embodiments, the limiting component 3 comprises a mounting seat 31, a limiting piece 32, and a locking piece 33. The limiting piece has a second axial direction c. The mounting seat 31 is fixedly connected to the connecting end of the light guide arm body 2. The locking piece 33 has a locked state and an unlocked state. When the locking piece 33 is in the unlocked state, the limiting piece 32 can be switched between the working position and the storage position. When the locking piece 33 is in the locked state, the limiting piece 32 is fixed on the mounting seat. By setting the locking piece 33 in the locked state, the limiting piece 32 can be fixed, which can be fixed in the working position, which plays a limiting role, limits the swing angle range of the light guide arm body, or is fixed in the storage position, which releases the swing angle range of the light guide arm body, so that the light guide arm body can freely swing to a convenient storage state. The unlocking state of the locking piece 33 can make the limiting piece 32 freely move to flexibly switch between the storage position and the working position. By setting the locking piece 33 and setting the limiting piece 32 and the mounting seat 31 as a movable connection structure, the position locking or unlocking between the limiting piece 32 and the mounting seat 31 can be realized by moving the locking piece 33. For example, a hole is opened on the surface of the limiting piece 32 and the mounting seat 31. When it is necessary to lock the limiting piece 32 and the mounting seat 31, the locking piece 33 is inserted into the hole to limit the rotation between them. When it is necessary to adjust the angle of the limiting piece 32, the locking piece 33 is pulled out of the hole to make the limiting piece 32 rotate relative to the mounting seat 31.

[0057] Since the principle of the limiting piece 32 limiting the swing of the light guide arm body 2 relative to the base 1 is that the limiting piece 32 is located on the swing path of the light guide arm body 2, by setting the locking piece 33 and setting the limiting piece 32 and the mounting seat 31 as a rotatable connection, when it is necessary to store the light guide arm, the limiting piece 32 and the mounting seat 31 can be unlocked by moving the locking piece 33 to the second position, and then the limiting piece 32 is rotated to make the limiting piece 32 leave the swing path of the light guide arm body 2, so as to realize the free swing of the light guide arm body 2, so that the light guide arm body 2 can swing to a convenient storage angle as needed, for example Figure 2 and Figure 3 The light guide arm body 2 is swung to be coplanar with the base 1, which greatly reduces the structural volume occupied by the light guide arm, and facilitates the transportation and storage of the light guide arm. At the same time, since the light guide arm does not need to be disassembled during transportation and storage, the components such as the light guide arm body 2, the limiting component 3, and the base 1 are not disassembled, so as to improve the convenience of transportation.

[0058] The mounting seat 31 can be mounted on the base 1 or the light guide arm body 2, which is used to fix the limiting piece 32. When the light guide arm body 2 swings relative to the base 1, the limiting piece 32 can limit the light guide arm body 2, and then the swing amplitude of the light guide arm body 2 can be limited to avoid collision with other structures of the equipment.

[0059] As shown in Figure 1 , the mounting seat 31 is mounted on the connecting end, when the light guide arm body 2 swings relative to the base 1, the mounting seat 31 and the limiting piece 32 are driven to swing, when the limiting piece 32 swings to abut against the base 1, at this time, the base 1 limits the light guide arm body 2 from continuing to swing through the limiting piece 32.

[0060] Referring to Figure 6 and Figure 8 , the limiting piece 32 in the locking state of the locking piece 33 is respectively in the working position and the storage position. Figure 5 An exploded schematic view of the limiting assembly 3 is shown.

[0062] In this embodiment, the first section 331 can be a multi-prism structure, for example Figure 4 the quadrangular prism structure in the figure, at this time, the shapes corresponding to the first insertion hole 312 and the second insertion hole 321 are also cuboids, and the sizes of the first insertion hole 312 and the second insertion hole 321 are adapted to the first section 331, so when the first section 331 is embedded in the first insertion hole 312 and the second insertion hole 321, the rotation between the limiting piece 32 and the mounting seat 31 can be effectively limited, so that it is in the locking state. When the locking piece 33 is moved to the first section 331 and the second insertion hole 321 are separated, at this time, the limiting piece 32 can not be stopped by the locking piece 33, and can rotate relative to the mounting seat 31.

[0063] Further, a circular chamfer is arranged on the outer circumferential surface of the first section 331 to improve the convenience when the first section 331 moves in the first insertion hole 312 and the second insertion hole 321.

The limiting piece 32 is sequentially provided with the second insertion hole 321 and the fourth insertion hole 322 along the axial direction of the second section 332, and the second insertion hole 321 and the fourth insertion hole 322 are adjacent and connected.

[0066] When the locking piece 33 is in the first position, that is, as shown in Figure 6 and Figure 7 The second section 332 of the locking piece 33 is inserted into the fourth insertion hole 322 and the third insertion hole 313, and the first section 331 is inserted into the first insertion hole 312 and the second insertion hole 321, at this time, the locking piece 33 is in the locked state, and under the limiting of the first section 331, the limiting piece 32 and the mounting base 31 remain in the locked state, and the limiting piece 32 limits the swing of the light guide arm body 2 in the first range.

[0067] When the locking piece 33 is in the second position, that is, as shown in Figure 8 and Figure 9 The second section 332 of the locking piece 33 is inserted into the second insertion hole 321, the fourth insertion hole 322 and the third insertion hole 313, and the first section 331 is away from the second insertion hole 321, at this time, the locking piece 33 is in the unlocked state, and the limiting piece 32 can rotate relative to the mounting base 31, at this time, the first section 331 also has the effect of rotationally connecting the limiting piece 32 and the mounting base 31, thereby simplifying the structure.
