[0009] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0011] The following reference Figures 1-38 A frame 100 for a surgical microscope 200 and a surgical microscope system 1000 are described according to embodiments of the present invention.

[0012] Combination Figures 1 to 9 According to an embodiment of the present invention, a frame 100 for a surgical microscope 200 includes: a mounting base 11, a rotating device 10, and a first angle limiting component 50. The rotating device 10 is mounted with the surgical microscope 200 and is rotatably connected to the mounting base 11. The first angle limiting component 50 cooperates with the mounting base 11 and the rotating device 10 respectively, and is used to limit the rotation angle of the rotating device 10.

[0013] For example, the mounting base 11 can serve as a mounting carrier for the rotating device 10, supporting and connecting the rotating device 10. The rotating device 10 is rotatably connected to the mounting base 11. The mounting base 11 can also provide a rotation reference for the rotating device 10 to ensure the rotation accuracy of the rotating device 10 and to reduce the risk of the rotating device 10 shifting. The rotating device 10 is equipped with a surgical microscope 200. By rotating the rotating device 10 relative to the mounting base 11, the surgical microscope 200 can be rotated, thereby adjusting the rotation angle of the surgical microscope 200 to meet different user needs.

[0014] Furthermore, considering that the surgical microscope 200 is equipped with a wire harness connected to it, if the rotating device 10 rotates freely around its rotation axis without restriction, the wire harness connected to the surgical microscope 200 may become tangled or even broken. Therefore, in order to protect the wire harness and improve the reliability of the electrical connection of the surgical microscope 200, the frame 100 of this application is equipped with a first angle limiting component 50. The first angle limiting component 50 cooperates with the mounting base 11 and the rotating device 10 respectively. For example, a part of the first angle limiting component 50 can be provided on the mounting base 11, and another part of the first angle limiting component 50 can be provided on the rotating device 10. When the rotating device 10 rotates to the point where the two parts of the first angle limiting component 50 stop, the rotating device 10 cannot rotate further, thereby limiting the rotation angle of the rotating device 10, and thus limiting the rotation angle of the surgical microscope 200, preventing the wire harness connected to the surgical microscope 200 from becoming tangled or even broken, thereby improving the reliability of the electrical connection of the surgical microscope 200.

[0015] It is understood that the way the first angle limiting component 50 limits the rotation angle of the rotating device 10 is merely an example for ease of understanding and should not be construed as a limitation of this application. The specific way the first angle limiting component 50 limits the rotation angle of the rotating device 10 can be determined according to actual production requirements and is not specifically limited here.

[0016] In related technologies, in order to improve the flexibility of use of surgical microscopes, the design of the frame for mounting the surgical microscope often focuses on how to increase the degree of freedom of movement of the frame, while ignoring the impact of excessive freedom of movement of the frame on the wiring harness. As a result, the wiring harness connected to the surgical microscope is easily pulled out when using the surgical microscope, affecting the reliability of the electrical connection of the surgical microscope.

[0017] This application sets a first angle limiting component 50, which can cooperate with the mounting base 11 and the rotating device 10 respectively. The first angle limiting component 50 is used to limit the rotation angle of the rotating device 10, thereby limiting the rotation angle of the surgical microscope 200 and preventing the wire harness connected to the surgical microscope 200 from getting tangled or even broken, so as to improve the reliability of the electrical connection of the surgical microscope 200.

[0018] Combination Figure 3 and Figure 4 In some embodiments of the present invention, the first angle limiting component 50 includes a limiting part 51 and a limiting mating part 52. The limiting part 51 is disposed in one of the mounting base 11 and the rotating device 10, and the limiting mating part 52 is disposed in the other of the mounting base 11 and the rotating device 10. In the rotation direction of the rotating device 10, the limiting part 51 is adapted to engage with the limiting mating part 52 to limit the rotation angle of the rotating device 10.

[0019] In some examples, the limiting part 51 can be provided on the mounting base 11, and the limiting mating part 52 can be provided on the rotating device 10. When the rotating device 10 rotates relative to the mounting base 11, the rotating device 10 can drive the limiting mating part 52 to rotate synchronously. When the rotating device 10 rotates to the point where it abuts against the limiting mating part 52 and the limiting part 51, since the limiting part 51 is located on the rotation path of the limiting mating part 52, it can prevent the limiting mating part 52 from rotating further, thereby preventing the rotating device 10 from rotating further, thus limiting the rotation angle of the rotating device 10.

[0020] In other examples, the limiting part 51 can be provided on the rotating device 10, and the limiting mating part 52 can be provided on the mounting base 11. The rotating device 10 can drive the limiting part 51 to rotate towards the limiting mating part 52. When the limiting part 51 and the limiting mating part 52 are in a stop-fitting engagement, the rotating shaft 16 device can be prevented from rotating further, thereby limiting the rotation angle of the rotating device 10.

[0021] Combination Figures 3 to 5 In some embodiments of the present invention, the rotating device 10 includes a first rotating shaft 110 and a first bearing 111. At least a portion of the first rotating shaft 110 is disposed in the mounting base 11 and rotates in cooperation with the mounting base 11. The first bearing 111 is sleeved on the first rotating shaft 110 and is provided with a limiting part 51 or a limiting cooperation part 52.

[0022] In some examples, the limiting engagement part 52 is provided on the mounting base 11, and the limiting part 51 is provided on the side of the first bearing 111 facing the mounting base 11. In the rotation direction of the rotating device 10, at least a portion of the limiting part 51 and the limiting engagement part 52 can be arranged opposite each other. When the rotating device 10 is driven to rotate, the first rotating shaft 110 can drive the first bearing 111 to rotate, and the first bearing 111 can drive the limiting part 51 to rotate towards the limiting engagement part 52. When the limiting engagement part 52 and the limiting part 51 are engaged, the first rotating shaft 110 can be limited by the first bearing 111, thereby limiting the rotation angle of the rotating device 10, and thus limiting the rotation angle of the surgical microscope 200.

[0023] In other examples, the limiting engagement part 52 is disposed on the first bearing 111, and the limiting part 51 is disposed on the mounting base 11. The limiting engagement part 52 is driven by the first bearing 111 to rotate toward the limiting part 51. When the limiting engagement part 52 and the limiting part 51 are engaged, the first rotating shaft 110 can be limited by the first bearing 111, thereby limiting the rotation angle of the rotating device 10, and thus limiting the rotation angle of the surgical microscope 200.

[0024] In the above technical solution, by setting the first bearing 111, it is beneficial to reduce the wear of the first rotating shaft 110 and extend its service life; by setting the limiting part 51 or the limiting mating part 52 on the first bearing 111, there is no need to set additional components for installing the limiting part 51 or the limiting mating part 52, which is beneficial to simplify the structure of the frame 100 and reduce the production cost of the frame 100.

[0025] Combination Figures 3 to 5 In some embodiments of the present invention, the first bearing 111 is provided with a first mating groove 1111 extending in the circumferential direction along the first rotating shaft 110, the limiting mating part 52 is a protrusion provided in the first mating groove 1111, the mounting base 11 is provided with a limiting part 51, the limiting part 51 extends into the first mating groove 1111, and is adapted to stop and engage with the limiting mating part 52 in the rotation direction of the rotating device 10.

[0026] For example, the limiting fitting part 52 can protrude toward the open end of the first fitting groove 1111, and the limiting part 51 can extend into the first fitting groove 1111 through the open end of the first fitting groove 1111. In the rotation direction of the rotating device 10, at least a portion of the limiting part 51 and the limiting fitting part 52 are arranged opposite to each other, so that the limiting part 51 can abut against the limiting fitting part 52 in the rotation direction of the limiting device, thereby limiting the rotation angle of the rotating device 10.

[0027] In some embodiments of the present invention, the limiting fitting part 52 is integrally formed with the first bearing 111, or the limiting fitting part 52 is part of the first bearing 111 and is located in the first fitting groove 1111. In this case, the rotation angle of the rotating device 10 can be determined by the circumferential dimension of the first fitting groove 1111 occupied by the limiting fitting part 52. For example, the rotation angle γ of the limiting part 51 rotating from one end of the limiting fitting part 52 to the other end can be 0°~170°.

[0028] In the above technical solution, by making the limiting mating part 52 and the first bearing 111 form an integral part, it is beneficial to simplify the structure of the rotating device 10, thereby simplifying the assembly steps of the rotating device 10 and improving the assembly efficiency of the rotating device 10.

[0029] like Figure 6 As shown, in some other embodiments of the present invention, a first sliding groove 1112 is provided in the first mating groove 1111, and the limiting mating part 52 is slidably mated with the first sliding groove 1112. The limiting part 51 is adapted to push the limiting mating part 52 to slide.

[0030] For example, the first mating groove 1111 is provided with a first sliding groove 1112 extending in an arc shape. A part of the limiting mating part 52 can be disposed in the first sliding groove 1112 and slide in cooperation with the first sliding groove 1112. Another part of the limiting mating part 52 can extend out from the first sliding groove 1112 and be disposed opposite to the limiting part 51 in the rotation direction of the rotating device 10.

[0031] After the rotating device 10 rotates and drives the limiting part 51 to contact the limiting mating part 52, the rotating device 10 rotates further so that the limiting part 51 can push the limiting mating part 52 to slide in the first slide groove 1112. When the limiting mating part 52 slides to abut against one side wall of the first slide groove 1112 in the rotation direction of the rotating device 10, the limiting mating part 52 can prevent the rotating device 10 from continuing to rotate through the limiting part 51, thereby limiting the rotation angle of the rotating device 10.

[0032] Therefore, by providing a first sliding groove 1112 in the first mating groove 1111 and making the limiting mating part 52 slide in the first sliding groove 1112, it is beneficial to increase the rotatable angle of the rotating device 10, thereby improving the rotatable angle range of the surgical microscope 200 and enhancing the flexibility of the surgical microscope 200 in use.

[0033] Understandably, the length of the first slide 1112 can be designed according to actual usage requirements to ensure that the range of rotation angles of the surgical microscope 200 can meet the usage requirements. For example, the length of the first slide 1112 can be increased to increase the unidirectional rotation angle of the rotating device 10 to meet the user's usage requirements.

[0034] In some embodiments of the present invention, the first groove 1112 is configured as a settling blind groove, and the groove wall of the first groove 1112 in the direction parallel to the rotation axis of the rotating device 10 is spaced apart from the end face of the first bearing 111 on the side away from the mounting base 11, so as to ensure the structural strength of the first mating groove 1111.

[0035] like Figure 3 As shown, in some embodiments of the present invention, a first mating groove 1111 is provided on the axial end face of the first bearing 111 in the axial direction of the first rotating shaft 110.

[0036] For example, one side axial end face of the first bearing 111 can be disposed opposite to the mounting base 11. The first mating groove 1111 is disposed on the axial end face of the first bearing 111 and can be recessed in a direction away from the mounting base 11. The end of the mounting base 11 opposite to the first bearing 111 can be provided with a limiting part 51. The limiting part 51 can extend into the first mating groove 1111 through the open end of the first mating groove 1111 so that the limiting part 51 can cooperate with the limiting mating part 52.

[0037] In other embodiments of the present invention, the first mating groove 1111 may be provided on the peripheral side wall of the first bearing 111 and open in the radial direction. At least a portion of the first bearing 111 may be provided in the mounting base 11. The portion of the mounting base 11 that is radially opposite to the first bearing 111 is provided with a limiting part 51. The limiting part 51 may extend into the first mating groove 1111 through the open end of the first mating groove 1111 so as to cooperate with the limiting mating part 52.

[0038] Combination Figure 2 and Figure 7 In some embodiments of the present invention, the rotating device 10 further includes a mounting bracket 12, which is axially connected to one end of the first rotating shaft 110 extending from the mounting base 11. The first bearing 111 is located between the first rotating shaft 110 and the mounting bracket 12, and the first rotating shaft 110 is rotatable relative to the mounting base 11.

[0039] For example, one axial end of the mounting bracket 12 is fixedly connected to the first rotating shaft 110, the first bearing 111 is located between the first rotating shaft 110 and the mounting bracket 12 in the radial direction, and a first mating groove 1111 is provided on one axial end face of the first bearing 111. The first mating groove 1111 can be arranged opposite to the mounting seat 11 in the axial direction.

[0040] By setting up the mounting bracket 12 and connecting one end of the mounting bracket 12 to the first rotating shaft 110, the first rotating shaft 110 can be positioned and installed. At the same time, the mounting bracket 12 can also protect the first bearing 111 and the first rotating shaft 110, thereby reducing the risk of damage to the first bearing 111 and the first rotating shaft 110.

[0041] Combination Figures 7 to 9 In some embodiments of the present invention, a second angle limiting component 60 is provided between the mounting bracket 12 and the first bearing 111. The second angle limiting component 60 is adapted to cooperate with the first angle limiting component 50 to limit the rotation angle of the first rotating shaft 110 relative to the mounting base 11. For example, the second angle limiting component 60 may be disposed between the side of the first bearing 111 away from the mounting base 11 and the mounting bracket 12, and a part of the second angle limiting component 60 may be disposed on the first bearing 111, and another part of the second angle limiting component 60 may be disposed on the mounting bracket 12.

[0042] In the rotation direction of the rotating device 10, when the limiting part 51 and the limiting mating part 52 are engaged, the rotation of the first bearing 111 is hindered. At this time, the first rotating shaft 110 can continue to rotate. When the two parts of the second angle limiting component 60 are engaged, a part of the second angle limiting component 60 provided on the mounting bracket 12 can be blocked by the first bearing 111. At this time, the mounting bracket 12 cannot continue to rotate, thereby preventing the first rotating shaft 110 from continuing to rotate. This achieves the limitation of the rotation angle of the first rotating shaft 110 relative to the mounting base 11.

[0043] Therefore, by setting the first angle limiting component 50 and the second angle limiting component 60 respectively, the first rotation shaft 110 can be limited in two ways, which is beneficial to increase the rotation angle range of the rotating device 10, thereby increasing the rotation angle range of the surgical microscope 200 and improving the rotation flexibility of the surgical microscope 200.

[0044] When the single-level limit (which can also be understood as the limit achieved by the first angle limit component 50) can make the unidirectional rotation angle range of the first rotating shaft 110 0°~170°, the second-level limit can make the maximum unidirectional rotation angle range of the first rotating shaft 110 0°~340°, effectively increasing the rotation angle range of the rotating device 10.

[0045] Combination Figures 7 to 9In some embodiments of the present invention, the second angle limiting component 60 includes a second mating groove 61 and a limiting protrusion 62. The limiting protrusion 62 extends into the second mating groove 61 and is adapted to abut against the end face of the second mating groove 61. The first bearing 111 is provided with one of the second mating groove 61 and the limiting protrusion 62, and the mounting bracket 12 is provided with the other of the second mating groove 61 and the limiting protrusion 62.

[0046] For example, the second mating groove 61 can be formed as an annular groove with one end open in the axial direction, and the second mating groove 61 is provided with a raised structure. The raised structure can block the second mating groove 61, and the two side walls of the raised structure in the extension direction of the second mating groove 61 are the end faces of the second mating groove 61. The limiting protrusion 62 can extend into the second mating groove 61 through the open end of the second mating groove 61 and slide in the second mating groove 61.

[0047] For ease of explanation, taking the example of the second mating groove 61 being provided on the first bearing 111 and the limiting protrusion 62 being provided on the mounting bracket 12, when the rotating device 10 rotates to the point where the limiting part 51 and the limiting mating part 52 are in a stop-fitting engagement, the first bearing 111 is locked. At this time, the first rotating shaft 110 can continue to rotate. When the rotating device 10 rotates further to the point where the limiting protrusion 62 and one side end face of the second mating groove 61 are in a stop-fitting engagement, the first bearing 111 can hinder the rotation of the limiting protrusion 62. Thus, the limiting protrusion 62 hinders the rotation of the mounting bracket 12, thereby hindering the rotation of the first rotating shaft 110. This limits the rotation angle of the rotating device 10, and thus limits the rotation angle of the surgical microscope 200.

[0048] In some embodiments of the present invention, a first sliding groove 1112 is provided in the first mating groove 1111, and the limiting mating part 52 is slidably engaged with the first sliding groove 1112, and the limiting part 51 is adapted to push the limiting mating part 52 to slide; and / or, a limiting boss is provided in the second mating groove 61, the limiting boss participates in defining the end face forming the second mating groove 61, and a second sliding groove is also provided in the second mating groove 61, the limiting boss is slidably engaged with the second sliding groove, and the limiting protrusion 62 is adapted to push the limiting boss to slide.

[0049] In some examples, the first mating groove 1111 is provided with a first sliding groove 1112 extending in an arc shape. A part of the limiting mating part 52 can be disposed in the first sliding groove 1112 and slide in cooperation with the first sliding groove 1112. The other part of the limiting mating part 52 can extend out of the first sliding groove 1112 and be disposed opposite to the limiting part 51 in the rotation direction of the rotating device 10. At the same time, the second mating groove 61 can be formed as an annular groove with one end open in the axial direction, and a limiting boss fixed in the second mating groove 61 is provided. The limiting boss can block the second mating groove 61. The two side walls of the limiting boss in the extension direction of the second mating groove 61 are the end faces of the second mating groove 61. The limiting protrusion 62 can extend into the second mating groove 61 through the open end of the second mating groove 61 and slide in the second mating groove 61.

[0050] After the rotating device 10 rotates and drives the limiting part 51 to contact the limiting mating part 52, the rotating device 10 rotates further so that the limiting part 51 can push the limiting mating part 52 to slide in the first slide groove 1112. When the limiting mating part 52 slides to abut against one side wall of the first slide groove 1112 in the rotation direction of the rotating device 10, the first bearing 111 is locked. At this time, the first rotating shaft 110 can continue to rotate. When the limiting protrusion 62 abuts against one side wall of the limiting boss, the mounting bracket 12 is blocked by the first bearing 111. At this time, the mounting bracket 12 cannot continue to rotate, thereby preventing the first rotating shaft 110 from continuing to rotate, thus limiting the rotation angle of the first rotating shaft 110 relative to the mounting base 11.

[0051] In other examples, the limiting engagement part 52 is fixed in the first engagement groove 1111, the second engagement groove 61 is provided with a limiting boss, the limiting boss participates in defining the end face forming the second engagement groove 61, the second engagement groove 61 is provided with a second sliding groove, the limiting boss and the second sliding groove are slidably engaged, and the limiting protrusion 62 is adapted to push the limiting boss to slide.

[0052] After the rotating device 10 rotates and drives the limiting part 51 to engage with the limiting mating part 52, the first bearing 111 is locked. At this time, the first rotating shaft 110 can continue to rotate. When the limiting protrusion 62 pushes the limiting boss to engage with the side wall of the second slide groove, the mounting bracket 12 is blocked by the first bearing 111. At this time, the mounting bracket 12 cannot continue to rotate, thereby preventing the first rotating shaft 110 from continuing to rotate. This achieves the limitation of the rotation angle of the first rotating shaft 110 relative to the mounting base 11.

[0053] In some other examples, the first mating groove 1111 is provided with a first sliding groove 1112, and the limiting mating part 52 is slidably engaged with the first sliding groove 1112. The limiting part 51 is adapted to push the limiting mating part 52 to slide. At the same time, the second mating groove 61 is provided with a limiting boss, which participates in defining the end face forming the second mating groove 61. The second mating groove 61 is provided with a second sliding groove, and the limiting boss is slidably engaged with the second sliding groove. The limiting protrusion 62 is adapted to push the limiting boss to slide.

[0054] After the rotating device 10 rotates and drives the limiting part 51 to contact the limiting mating part 52, the rotating device 10 rotates further so that the limiting part 51 can push the limiting mating part 52 to slide in the first slide groove 1112. When the limiting mating part 52 slides to abut against one side wall of the first slide groove 1112 in the rotation direction of the rotating device 10, the first bearing 111 is locked. At this time, the first rotating shaft 110 can continue to rotate. When the limiting protrusion 62 pushes the limiting boss to slide to abut against one side wall of the second slide groove, the mounting bracket 12 is blocked by the first bearing 111. At this time, the mounting bracket 12 cannot continue to rotate, thereby preventing the first rotating shaft 110 from continuing to rotate, thus limiting the rotation angle of the first rotating shaft 110 relative to the mounting base 11.

[0055] Therefore, by setting the first angle limiting component 50 and the second angle limiting component 60 respectively, a two-stage limiting of the first rotating shaft 110 can be achieved, which is beneficial to increasing the rotation angle range of the rotating device 10. By further setting the first sliding groove 1112 in the first mating groove 1111 and making the limiting mating part 52 slide in the first sliding groove 1112, and / or setting the second sliding groove in the second mating groove 61 and making the limiting boss slide in the second sliding groove, the unidirectional rotation angle range of the first rotating shaft 110 can reach 360° or more, which is beneficial to further increase the rotatable angle of the rotating device 10, thereby benefiting the rotatable angle range of the surgical microscope 200.

[0056] like Figure 7 As shown, in some embodiments of the present invention, a second locking unit 70 is provided in the mounting base 11, and the first rotating shaft 110 is connected to the second locking unit 70. The second locking unit 70 can selectively lock the first rotating shaft 110 to prevent the rotating device 10 from rotating due to accidental contact.

[0057] In some specific embodiments of the present invention, the second locking unit 70 is configured as an electromagnetic brake, combined with Figure 36 and Figure 37The electromagnetic brake includes: a fixed plate 71, a friction disc 72, a spring 74, a movable plate 73, a brake body 76, and a support frame 75 at least supported on the brake body 76, arranged sequentially along the axial direction. The fixed plate 71 is mounted on a mounting base 11. The end of the first rotating shaft 110 away from the mounting base 11 in the axial direction is connected to the spring 74 through a threaded connection. At the same time, the friction disc 72 is connected to the spring 74 through a threaded connection, and the connection point between the friction disc 72 and the spring 74 is located at the outer edge of the spring 74. The movable plate 73 is disposed between the friction disc 72 and the brake body 76. The brake body 76 is provided with at least one elastic drive member, which is connected to the movable disc and is used to drive the movable plate 73 to slide in the axial direction, so that the movable plate 73 can selectively clamp the friction disc 72 onto the fixed plate 71.

[0058] Specifically, when the electromagnetic brake is energized, the brake body 76 generates electromagnetic force and attracts the moving plate 73 onto the brake body 76. At this time, the elastic drive member is in a compressed state, the friction disc 72 is not pressed against the fixed plate 71 by the moving plate 73, and the spring 74 is not deformed. At this time, the first rotating shaft 110 can drive the friction disc 72 to rotate synchronously through the spring 74.

[0059] When the electromagnetic brake is de-energized, the electromagnetic force generated by the brake body 76 disappears. The movable plate 73 located on the brake body 76 can move towards the fixed plate 71 under the drive of the elastic drive member. The movable plate 73 can drive the friction disc 72 to move towards the fixed plate 71. During this process, the friction disc 72 drives the spring 74 to deform. When the movable plate 73 presses the friction disc 72 onto the fixed plate 71, the fixed plate 71 and the movable plate 73 can clamp the friction disc, and the friction disc 72 cannot rotate, thereby locking the first rotating shaft 110.

[0060] In related technologies, in order to ensure that the friction disk can slide relative to the rotating shaft in the axial direction and to lock the rotating shaft by clamping the friction disk, the friction disk and the rotating shaft are usually coaxially fitted by a keyway structure. However, the keyway structure usually causes a gap between the rotating shaft and the friction disk, which causes the rotating shaft to rotate and wobble, affecting the reliability and stability of the rotating device and the surgical microscope.

[0061] By using a spring 74 to connect the first rotating shaft 110 to the friction disk 72, this application can ensure that the friction disk 72 can move in the axial direction and selectively lock the first rotating shaft 110. It can also avoid the rotational stability of the first rotating shaft 110 due to the presence of a fit gap between the friction disk 72 and the first rotating shaft 110, thereby improving the stability of the rotating device 10 and the surgical microscope 200.

[0062] Combination Figures 10 to 15In some embodiments of the present invention, the rotating device 10 includes: a mounting bracket 12, a first drive motor 13, a rotating arm 14, and a transmission mechanism 15. The first drive motor 13 is fixed to the mounting bracket 12. The rotating arm 14 is equipped with a surgical microscope 200. The transmission mechanism 15 is connected to at least the first drive motor 13, the rotating arm 14, and the surgical microscope 200. The first drive motor 13 drives the rotating arm 14 to rise and fall relative to the mounting bracket 12 and the surgical microscope 200 to rotate relative to the rotating arm 14 through the transmission mechanism 15.

[0063] For example, combined Figure 16 and Figure 17 The mounting bracket 12 can serve as a mounting carrier for the first drive motor 13, providing stable support for the first drive motor 13. The first drive motor 13 is equipped with a first motor adapter 19, and can be mounted on the mounting bracket 12 through the first motor adapter 19, thereby improving the installation convenience and assembly stability of the first drive motor 13.

[0064] The transmission mechanism 15 may include two parts. One part is connected between the first drive motor 13 and the rotating arm 14, and the connection positions of the first drive motor 13 and the rotating arm 14 with the transmission mechanism 15 are spaced apart. The first drive motor 13 can drive the rotating arm 14 to rise and fall through the transmission mechanism 15 connected between it and the rotating arm 14. Specifically, the first drive motor 13 can drive the transmission mechanism 15 connected to it to rotate around the output shaft of the first drive motor 13. During the rotation of the transmission mechanism 15, the height of the end of the transmission mechanism 15 away from the first drive motor 13 in the vertical direction changes, thereby driving the rotating arm 14 to rise and fall, which can drive the surgical microscope 200 to rise and fall, so as to adjust the height of the surgical microscope 200.

[0065] Another part of the transmission mechanism 15 can be connected to the surgical microscope 200. During the process of the first drive motor 13 driving the rotating arm 14 to rise and fall relative to the mounting bracket 12 through the transmission mechanism 15, the first drive motor 13 can also drive the surgical microscope 200 to rotate relative to the rotating arm 14 through the part of the transmission mechanism 15 connected to the surgical microscope 200, so as to adjust the rotation angle of the surgical microscope 200.

[0066] Therefore, the rotating device 10 can not only adjust the height of the surgical microscope 200, but also adjust the rotation angle of the surgical microscope 200, thereby improving the degree of freedom of movement of the surgical microscope 200, which is conducive to meeting different user needs and improving the user experience.

[0067] Combination Figures 10 to 15In some embodiments of the present invention, the transmission mechanism 15 includes: a first transmission component 151, one end of the first transmission component 151 is connected to the mounting bracket 12 and the first drive motor 13 respectively, the first drive motor 13 is used to drive the first transmission component 151 to rotate around the first axis, and the other end of the first transmission component 151 is connected to at least the rotating arm 14, the first transmission component 151 is used to drive the rotating arm 14 to rise and fall.

[0068] It should be noted that the first axis is parallel or collinear with the central axis of the output shaft of the first drive motor 13.

[0069] For example, one end of the first transmission component 151 is connected to the first drive motor 13 and rotatably connected to the mounting bracket 12. The end of the first transmission component 151 away from the first drive motor 13 can be connected to at least the rotating arm 14. The first drive motor 13 can drive the first transmission component 151 to rotate around the first axis. During the rotation of the first transmission component 151 around the first axis, the height of the end of the first transmission component 151 away from the first drive motor 13 changes in the vertical direction, so as to drive the rotating arm 14 to rise and fall. The surgical microscope 200 is mounted on the rotating arm 14, so the rotating arm 14 can drive the surgical microscope 200 to rise and fall, thereby adjusting the height of the surgical microscope 200.

[0070] Furthermore, the transmission mechanism 15 also includes a second transmission component 152, which is movably disposed within the rotating arm 14. The second transmission component 152 is connected to the first transmission component 151 and the surgical microscope 200 respectively. The first transmission component 151 is adapted to drive the surgical microscope 200 to rotate relative to the rotating arm 14 through the second transmission component 152. That is, during the process of the first drive motor 13 driving the rotating arm 14 to rise and fall through the first transmission component 151, the first transmission component 151 can also drive the second transmission component 152 to move within the rotating arm 14. The second transmission component 152 is connected to the surgical microscope 200 so that the first transmission component 151 can drive the surgical microscope 200 to rotate relative to the rotating arm 14 through the second transmission component 152, thereby realizing the adjustment of the rotation angle of the surgical microscope 200.

[0071] Reference Figure 15In some embodiments of the present invention, the first transmission assembly 151 includes: a first connecting rod 1511 and a second connecting rod 1512. One end of the first connecting rod 1511 is connected to the first drive motor 13, and the other end of the first connecting rod 1511 is connected to the rotating arm 14 and the second transmission assembly 152 respectively. The first drive motor 13 drives the second transmission assembly 152 through the first connecting rod 1511. The second connecting rod 1512 is spaced apart from the first connecting rod 1511. The two ends of the second connecting rod 1512 are respectively hinged to the mounting bracket 12 and the rotating arm 14. The first drive motor 13 drives the rotating arm 14 to rise and fall through the first connecting rod 1511 and the second connecting rod 1512.

[0072] For example, the first link 1511 is rotatably connected to the rotating arm 14, and the second link 1512 is parallel to and spaced apart from the first link 1511. The second link 1512 is rotatably connected to the mounting bracket 12 and the rotating arm 14 respectively. The connection points of the first link 1511 and the first drive motor 13, the first link 1511 and the rotating arm 14, the second link 1512 and the mounting bracket 12, and the second link 1512 and the rotating arm 14 are distributed at the four vertices of a parallelogram. The first link 1511, the second link 1512, the mounting bracket 12, and the rotating arm 14 form a parallelogram mechanism, so that the first drive motor 13 can drive the rotating arm 14 to translate and lift through the first transmission assembly 151, and it is beneficial to distribute the load to improve the stability of the lifting and lowering of the rotating arm 14, thereby improving the stability of the rotating arm 14 driving the surgical microscope 200 to lift and lower.

[0073] A portion of the first connecting rod 1511 extends into the rotating arm 14 and is connected to the second transmission assembly 152. While the first drive motor 13 drives the first connecting rod 1511 to rotate around the first axis, the first connecting rod 1511 can drive the second transmission assembly 152 to move within the rotating arm 14, thereby driving the surgical microscope 200 to rotate relative to the rotating arm 14 through the second transmission assembly 152.

[0074] like Figure 15 As shown, in some embodiments of the present invention, the first connecting rod 1511 includes: a first rod 1 and a yaw rod 2. One end of the first rod 1 is connected to the first drive motor 13, and the yaw rod 2 is connected to the other end of the first rod 1 and disposed in the rotating arm 14. The yaw rod 2 is connected to the second transmission assembly 152, and the first rod 1 drives the second transmission assembly 152 to move through the yaw rod 2.

[0075] For example, when the first drive motor 13 drives the first rod 1 to rotate around the first axis, the first rod 1 can drive the yaw rod 2 to rotate relative to the rotating arm 14 within the rotating arm 14. The end of the yaw rod 2 away from the first rod 1 is connected to the second transmission assembly 152, so that the first rod 1 can drive the second transmission assembly 152 to move relative to the rotating arm 14 within the rotating arm 14 through the yaw rod 2, thereby driving the surgical microscope 200 to rotate relative to the rotating arm 14.

[0076] like Figure 15 As shown, in some embodiments of the present invention, the rotating arm 14 is provided with a limiting groove 141 at one end where the surgical microscope 200 is mounted, and the second transmission assembly 152 is provided with a first connecting shaft 1521. The first connecting shaft 1521 passes through the limiting groove 141 and is connected to the surgical microscope 200, and the first connecting shaft 1521 is adapted to slide with the limiting groove 141.

[0077] For example, the end of the second transmission assembly 152 away from the deflection rod 2 is hinged to the surgical microscope 200 via the first connecting shaft 1521. When the first drive motor 13 drives the first connecting rod 1511 to rotate, the first connecting rod 1511 can pull the second transmission assembly 152 to move within the rotating arm 14. The second transmission assembly 152 drives the first connecting shaft 1521 to slide within the limiting groove 141, and can pull the surgical microscope 200 to rotate relative to the rotating arm 14 via the first connecting shaft 1521.

[0078] The limiting groove 141 can guide and limit the sliding of the first connecting shaft 1521. By limiting the sliding distance of the first connecting shaft 1521, the rotation angle of the surgical microscope 200 relative to the rotating arm 14 is limited, which prevents the wire harness electrically connected to the surgical microscope 200 from getting tangled or even broken due to the excessive rotation angle of the surgical microscope 200. This helps to ensure the reliability of the electrical connection of the surgical microscope 200.

[0079] It is understandable that the length of the limiting groove 141 can be determined according to actual usage requirements, and no specific limitation is made here.

[0080] Reference Figure 15 In some embodiments of the present invention, the rotating device 10 further includes a rotating shaft 16 connected to the rotating arm 14 and the surgical microscope 200 respectively. The rotating shaft 16 is located at one end of the rotating arm 14 where the surgical microscope 200 is mounted, and is offset from the limiting groove 141. The first drive motor 13 is adapted to drive the surgical microscope 200 to rotate around the central axis of the rotating shaft 16 through the transmission mechanism 15.

[0081] For example, the limiting groove 141 is configured as an arc-shaped slide groove located on the circumferential outer side of the rotating shaft 16. The first drive motor 13 can drive the first connecting shaft 1521 to slide in the limiting groove 141 along the circumferential direction of the rotating shaft 16 through the first transmission assembly 151 and the second transmission assembly 152. Furthermore, the first connecting shaft 1521 pulls the surgical microscope 200 to rotate around the central axis of the rotating shaft 16, thereby realizing the rotation of the surgical microscope 200 relative to the rotating arm 14. The rotation center line of the surgical microscope 200 relative to the rotating arm 14 is the central axis of the rotating shaft 16.

[0082] Combination Figure 11 and Figure 15 In some embodiments of the present invention, the rotating arm 14 includes an upper swing arm 142 and a lower swing arm 143. One end of the upper swing arm 142 is connected to the first transmission assembly 151, and the lower swing arm 143 is connected to the other end of the upper swing arm 142. A limiting groove 141 is provided at the end of the lower swing arm 143 away from the upper swing arm 142, and a surgical microscope 200 is installed thereon. The upper swing arm 142 and the lower swing arm 143 are arranged at an angle.

[0083] In the above technical solution, by arranging the upper swing arm 142 and the lower swing arm 143 at an angle, a space can be formed between the upper swing arm 142 and the lower swing arm 143 to avoid the surgical microscope 200. This helps to prevent the rotating arm 14 from obstructing the user's field of view, and at the same time helps to prevent the surgical microscope 200 from interfering with the rotating arm 14 when rotating relative to the rotating arm 14, thus ensuring the rotation effect of the surgical microscope 200.

[0084] Combination Figure 10 , Figure 11 and Figure 37 In some embodiments of the present invention, the included angle α between the upper swing arm 142 and the lower swing arm 143 satisfies: 100°≤α≤120°. Considering that when one eyepiece of the surgical microscope 200 is positioned opposite the rotating arm 14 and between the upper swing arm 142 and the lower swing arm 143, if the angle between the upper swing arm 142 and the lower swing arm 143 is unreasonable, it may prevent the user from using the eyepiece. Therefore, this application designs the angle between the upper swing arm 142 and the lower swing arm 143 to ensure that α satisfies: 100°≤α≤120°, thereby increasing the space between the upper swing arm 142 and the lower swing arm 143 for the surgical microscope 200 to avoid obstruction, ensuring the convenience of the user in using the surgical microscope 200. At the same time, it helps to reduce the space occupied by the rotating arm 14, and thus helps to reduce the space occupied by the frame 100, so as to avoid the frame 100 occupying too much space in the operating room and affecting the arrangement of other equipment in the operating room.

[0085] Preferably, α can be 106°.

[0086] In some embodiments of the present invention, the minimum vertical distance between the surgical microscope 200 and the central axis of the rotation axis 16 is defined as L1, and the vertical distance between the end of the lower swing arm 143 connected to the upper swing arm 142 and the central axis of the rotation axis 16 is defined as L2, where L2 > L1, in order to further improve the avoidance effect of the rotating arm 14 on the surgical microscope 200 and prevent the surgical microscope 200 from interfering with or colliding with the rotating arm 14 when rotating relative to the rotating arm 14.

[0087] like Figure 15 As shown, in some embodiments of the present invention, the second transmission assembly 152 includes: an upper connecting rod 1522, a lower connecting rod 1523, and an eccentric bearing 1524. The upper connecting rod 1522 is disposed in the upper swing arm 142 and connected to the first transmission assembly 151. The lower connecting rod 1523 is disposed in the lower swing arm 143, and a first connecting shaft 1521 is provided at the end of the lower connecting rod 1523 away from the upper connecting rod 1522. The eccentric bearing 1524 is rotatably disposed in the rotating arm 14 and is located at the junction of the upper swing arm 142 and the lower swing arm 143, and is hinged to the upper connecting rod 1522 and the lower connecting rod 1523 respectively.

[0088] For example, the upper connecting rod 1522 can be connected to the oscillating rod 2, and the lower connecting rod 1523 can be hinged to the surgical microscope 200 via the first connecting shaft 1521. An eccentric bearing 1524 rotatable relative to the rotating arm 14 is provided between the upper connecting rod 1522 and the lower connecting rod 1523. The upper connecting rod 1522 and the lower connecting rod 1523 can be hinged to the eccentric bearing 1524 respectively, and the connection points of the upper connecting rod 1522 and the eccentric bearing 1524 and the lower connecting rod 1523 and the eccentric bearing 1524 are located on both sides of the rotation center of the eccentric bearing 1524. The rotation center line of the eccentric bearing 1524 is parallel to the first axis.

[0089] When the first drive motor 13 drives the first transmission assembly 151 to rotate around the first axis, the first transmission assembly 151 can drive the upper connecting rod 1522 to move away from or towards the rotation center of the eccentric bearing 1524. For example, Figure 15As shown, when the first drive motor 13 drives the first transmission assembly 151 to rotate counterclockwise around the first axis, the first transmission assembly 151 can pull the upper connecting rod 1522 to move away from the rotation center of the eccentric bearing 1524. The upper connecting rod 1522 drives the eccentric bearing 1524 to rotate counterclockwise. The eccentric bearing 1524 further drives the first connecting shaft 1521 to slide closer to the eccentric bearing 1524 in the limiting groove 141. The first connecting shaft 1521 drives the surgical microscope 200 to rotate counterclockwise around the central axis of the rotation shaft 16. When the first drive motor 13 drives the first transmission assembly 151 to rotate clockwise around the first axis, the movement directions of the upper connecting rod 1522, the eccentric bearing 1524, the lower connecting rod 1523, and the first connecting shaft 1521 are all opposite to the above movement directions, thereby driving the surgical microscope 200 to rotate clockwise around the central axis of the rotation shaft 16, thereby adjusting the rotation angle of the surgical microscope 200 relative to the rotating arm 14.

[0090] In some specific examples of the present invention, the surgical microscope 200 can rotate about the central axis of the rotation axis 16 relative to the rotating arm 14 at an angle ranging from -45° to 45°.

[0091] Combination Figure 10 , Figure 16 and Figure 18 In some embodiments of the present invention, the rotating device 10 further includes: a microscope connecting seat 17 and a second drive motor 18 for driving the surgical microscope 200 to rotate around a second axis. The microscope connecting seat 17 is connected to the first connecting shaft 1521 and the rotating shaft 16 respectively. The second drive motor 18 is disposed on the microscope connecting seat 17 and connected to the surgical microscope 200. The second drive motor 18 is adapted to drive the surgical microscope 200 to rotate around the rotating shaft 16 under the drive of the second transmission assembly 152. The second axis is perpendicular to the first axis.

[0092] For example, the lower connecting rod 1523 is hinged to the microscope connecting seat 17 via the first connecting shaft 1521, and the lower swing arm 143 is hinged to the microscope connecting seat 17 via the rotating shaft 16. The microscope connecting seat 17 can be used to install the second drive motor 18. The output shaft of the second drive motor 18 can be connected to the surgical microscope 200 via the second motor adapter flange sleeve 181. Thus, the surgical microscope 200 can be mounted on the rotating arm 14.

[0093] The first drive motor 13 can drive the microscope connecting seat 17 to rotate relative to the rotating arm 14 around the central axis of the rotating shaft 16 via the transmission mechanism 15. The microscope connecting seat 17 can drive the surgical microscope 200 to rotate relative to the rotating arm 14 around the central axis of the rotating shaft 16 via the second drive motor 18. The second drive motor 18 can drive the surgical microscope 200 to rotate around a second axis independently. Thus, the surgical microscope 200 can rotate around different axes to improve the rotational freedom of the surgical microscope 200, thereby meeting different user needs and improving the user experience.

[0094] Combination Figure 1 , Figure 19 , Figure 23 and Figure 25 In some embodiments of the present invention, the frame 100 further includes a lifting device 20 for adjusting the height of the surgical microscope 200, and the mounting bracket 12 is rotatably connected to the lifting device 20 about a third axis to adjust the rotation angle of the surgical microscope 200.

[0095] For example, one end of the lifting device 20 is provided with a mounting base 11, and the mounting bracket 12 can be connected to the mounting base 11 and can rotate relative to the mounting base 11 about a third axis, so that the rotating device 10 can rotate relative to the lifting device 20 about the third axis. The rotating device 10 can drive the surgical microscope 200 to rotate about the third axis, so as to further improve the rotational freedom of the surgical microscope 200. At the same time, the lifting device 20 can drive the rotating device 10 to move in the vertical direction, so as to further adjust the height of the surgical microscope 200 mounted on the rotating device 10, thereby improving the flexibility of use of the surgical microscope 200 through the frame 100, which is conducive to further improving the user experience.

[0096] It should be noted that the center of gravity of the surgical microscope 200 should be as close as possible to the third axis to reduce the eccentric force generated when the surgical microscope 200 rotates, thereby helping to reduce the wear of the frame 100 and extend the service life of the frame 100.

[0097] Furthermore, combined Figure 1 , Figures 19 to 21 as well as Figure 23 and Figure 24 To the diagram and Figure 27 and Figure 28Considering that the surgical microscope 200 and the rotating device 10 have their own weight, after the surgical microscope 200 is adjusted to a position that meets the user's needs, the surgical microscope 200 and the rotating device 10 may cause the lifting device to move in the opposite direction under the action of gravity, which may cause the surgical microscope 200 to fall. In order to ensure that the surgical microscope 200 can remain stable during the operation and prevent the surgical microscope 200 from falling and causing its position to shift, the frame 100 of this embodiment of the application also includes a first locking component. The first locking component cooperates with the lifting device 20 to be suitable for positioning the rotating device 10 at the current height.

[0098] It should be noted that "current height" can be understood as the height at which the surgical microscope 200 is moved to meet the user's needs.

[0099] For example, after the height of the surgical microscope 200 is adjusted to a suitable position, the first locking component can cooperate with the lifting device 20 and lock the lifting device 20. The locking of the lifting device 20 by the first locking component can counteract the external force acting on the lifting device 20, so that the lifting device 20 can be positioned at the current position. This can achieve the positioning of the rotating device 10 at the current height, so as to ensure the stability of the position of the surgical microscope 200 during the surgical operation.

[0100] It should be noted that "the external force acting on the lifting device 20" can be understood as the gravity and / or external collision force of the surgical microscope 200 and the rotating device 10.

[0101] Combination Figures 19 to 21 as well as Figures 23 to 26 In some embodiments of the present invention, considering the limited space in the operating room, in order to prevent collisions caused by excessive lifting of the lifting device 20, the frame 100 further includes a limiting unit 30, which is disposed on the rotating device 10 and / or the lifting device 20, and is used to prevent the rotating device 10 from exceeding the limit height.

[0102] It should be noted that the limiting unit 30 can prevent the rotating device 10 from exceeding the limit height in the following ways: either by physically limiting the lifting device 20 to prevent it from continuing to work, thereby preventing the rotating device 10 from exceeding the limit height; or by the limiting unit 30 cooperating with the first locking component and controlling the first locking component to work through an output signal, so that the first locking component prevents the lifting device 20 from continuing to work, thereby preventing the rotating device 10 from exceeding the limit height; in addition, "limit height" refers to the maximum lifting height that can prevent the rotating device 10 from excessively lifting and lowering and causing a collision.

[0103] To facilitate understanding, we will take the example of the lifting device 20 being composed of a gear and rack.

[0104] In some examples, a portion of the limiting unit 30 may be located on the rack, and another portion of the limiting unit 30 may be located on the rotating device 10. When the rotating device 10 reaches its maximum height, the portion of the limiting unit 30 located on the rack may engage with the other portion of the limiting unit 30 located on the rotating device 10 to prevent the gear from continuing to drive the rack, thereby preventing the lifting device 20 from continuing to work and preventing the rotating device 10 from exceeding its maximum height.

[0105] In other examples, the limiting unit 30 is located on the rotating device 10 and is configured as a position sensor. The limiting unit 30 can detect the height of the rotating device 10 and feed back a corresponding signal. The first locking component can selectively cooperate with the lifting device 20 according to the signal fed back by the limiting unit 30, thereby selectively preventing the lifting device 20 from continuing to work.

[0106] It should be noted that the configuration of the limiting unit 30 and the method by which the limiting unit 30 prevents the rotating device 10 from exceeding the limit height are merely examples for ease of understanding and should not be construed as limitations on this application. The specific configuration of the limiting unit 30 and the specific method by which the limiting unit 30 prevents the rotating device 10 from exceeding the limit height can be determined according to actual production requirements and are not specifically limited here. Figures 19 to 21 as well as Figures 23 to 26 In some embodiments of the present invention, when the rotating device 10 is raised to the limit height, the limiting unit 30 can be triggered, and the first locking component is adapted to selectively lock the lifting device 20 according to the triggering state of the limiting unit 30 to position the rotating device 10.

[0107] For example, the limiting unit 30 includes a pressure block 31 and a contact switch 32. The pressure block 31 is located at one end of the lifting device 20 connected to the rotating device 10. The lifting device 20 is rotatably connected to the rotating device 10. The contact switch 32 is located on the rotating device 10, and at least a portion of the contact switch 32 is disposed opposite to the pressure block 31. The lifting device 20 drives the pressure block 31 to rotate relative to the contact switch 32.

[0108] When the lifting device 20 is in a horizontal position, the pressure block 31 and the contact switch 32 are spaced apart. When the lifting device 20 is raised, it can rotate relative to the rotating device 10 and drive the pressure block 31 to rotate toward the contact switch 32. When the rotating device 10 is raised to its limit height, the pressure block 31 rotates to engage with the contact switch 32, and the pressure block 31 presses against the contact switch 32 to close the contact switch 32. At this time, the contact switch 32 is triggered and can send a feedback signal. The first locking component engages with the lifting device 20 and locks the lifting device 20 to prevent the lifting device 20 from further raising the rotating device 10. This helps to reduce the risk of collision and improves the safety and service life of the frame 100 or the surgical microscope 20.

[0109] In other embodiments of the present invention, the limiting unit 30 may also be configured as a photoelectric switch, a position sensor, a reflective photoelectric switch, or a through-beam photoelectric switch, etc. The signal transmitting end of the limiting unit 30 may be disposed on the rotating device 10, and the signal receiving end may be disposed on the lifting device 20. It is understood that as long as the signal receiving end can receive the signal transmitted by the signal transmitting end when the rotating device 10 is raised to the limit height, the specific installation position is not specifically limited here.

[0110] Combination Figure 19 , Figure 20 , Figure 23 and Figure 25 In some embodiments of the present invention, the frame 100 further includes a base 40, and the lifting device 20 includes a lifting arm 21. The lifting arm 21 includes a first arm 213 and a second arm 214 arranged in the height direction. One end of the first arm 213 and the second arm 214 are respectively rotatably connected to the base 40, and the other end of the first arm 213 and the second arm 214 are respectively rotatably connected to the rotating device 10. The first arm 213 is adapted to drive the second arm 214 to rotate synchronously.

[0111] For example, the two ends of the first arm 213 are rotatably connected to the mounting base 11 and the base 40 of the rotating device 10, respectively, and the second arm 214 is disposed below the first arm 213, and the two ends of the second arm 214 can be rotatably connected to the mounting base 11 and the base 40 of the rotating device 10, respectively.

[0112] The connection points of the first arm 213 and the mounting base 11, the first arm 213 and the base 40, the second arm 214 and the mounting base 11, and the second arm 214 and the base 40 are distributed at the four vertices of a parallelogram. The first arm 213, the second arm 214, the mounting base 11, and the base 40 form a parallelogram mechanism. The first arm 213 can drive the second arm 214 to rotate synchronously relative to the base 40 through the mounting base 11. During the lifting and lowering process of the lifting arm 21, the first arm 213 and the mounting base... The connection point of the lifting arm 21 and the connection point of the second arm 214 with the mounting base 11 remain relatively stationary, so that during the process of the lifting device 20 driving the rotating device 10 to rise and fall, the rotating device 10 only undergoes translational movement along the height direction, avoiding the rotation of the rotating device 10 when the lifting device 20 drives the rotating device 10 to rise and fall, so as to ensure the uniqueness of the motion trajectory of the rotating device 10 during the rise and fall, and prevent the generation of invalid degrees of freedom. At the same time, the arrangement of the first arm 213 and the second arm 214 also helps to distribute the load and improve the load-bearing capacity and stability of the lifting arm 21.

[0113] Combination Figure 20 , Figure 23 and Figure 24 or combination Figure 27 and Figure 28 In some embodiments of the present invention, the lifting device 20 further includes a lifting drive 22, which is rotatably connected between the base 40 and the first support arm 213, and the length of the lifting drive 22 is adjustable to drive the first support arm 213 to rotate and change its height.

[0114] For example, the lifting drive 22 is connected between the base 40 and the first support arm 213. During the extension and retraction process, the lifting drive 22 can push and pull the first support arm 213. The driving force generated by the lifting drive 22 during extension and retraction can drive the first support arm 213 to rotate relative to the base 40 around the fourth axis. The first support arm 213 can drive the second support arm 214 to rotate synchronously around the fourth axis through the mounting base 11, so that the lifting support arm 21 rotates relative to the base 40.

[0115] It should be noted that the fourth axis is parallel or collinear with the central axis of the connecting axis described below, and the first, third and fourth axes are perpendicular to each other.

[0116] For example, when the lifting drive 22 extends, it can push the first arm 213 to a position close to the mounting base 11. Since the other end of the first arm 213 is rotatably connected to the base 40, under the pushing action of the lifting drive 22, the first arm 213 can rotate around the connecting axis rotatably connected to the base 40. At this time, the end of the first arm 213 connected to the mounting base 11 moves upward to drive the rotating device 10 to move upward, thereby lifting the surgical microscope 200.

[0117] When the lifting drive 22 is shortened, it can pull the end of the first arm 213 near the mounting base 11 inward. Under the pulling force of the lifting drive 22, the end of the first arm 213 connected to the base 40 rotates in the opposite direction around the connecting axis rotatably connected to the base 40. At this time, the end of the first arm 213 connected to the mounting base 11 moves downward to drive the rotating device 10 to move downward, thereby reducing the height of the surgical microscope 200.

[0118] Therefore, adjusting the height of the surgical microscope 200 improves its ease of use and enhances the user experience.

[0119] In some specific embodiments of the present invention, the lifting drive component 22 can be configured as a cylinder, hydraulic cylinder or gas spring, etc. The specific configuration of the lifting drive component 22 can be determined according to actual production requirements, and is not specifically limited here.

[0120] Combination Figures 23 to 26 In some embodiments of the present invention, the first locking component includes a first locking unit 33, which is disposed on the connecting shaft of the first support arm 213 or the second support arm 214 and the rotating device 10, and the first locking unit 33 is adapted to selectively lock the lifting device 30 according to the triggering state of the limiting unit 30.

[0121] For example, one end of the first arm 213 facing the rotating device 10 is provided with a connecting shaft, and one end of the second arm 214 facing the rotating device 10 is provided with a connecting shaft. The first arm 213 and the second arm 214 are rotatably connected to the mounting base 11 of the rotating device 10 through their corresponding connecting shafts. The first locking unit 33 can be provided on the connecting shaft corresponding to the first arm 213, or the first locking unit 33 can be provided on the connecting shaft corresponding to the second arm 214.

[0122] When the rotating device 10 is raised to its limit height, the limiting unit 30 is triggered. The limiting unit 30 can output a signal to make the first locking unit 33 cooperate with the lifting device 30. For example, the first locking unit 33 can lock the connecting shaft in the rotation direction of the connecting shaft to prevent the lifting device 20 from continuing to rotate relative to the base 40, thereby locking the lifting device 20 and preventing the lifting device 20 from further driving the surgical microscope 200 to rise through the rotating device 10, thus reducing the risk of collision.

[0123] Combination Figures 19 to 21 as well as Figures 23 to 26 In some embodiments of the present invention, the first locking unit 33 is configured as an electromagnetic brake.

[0124] For example, the electromagnetic brake can cooperate with the connecting shaft to selectively lock the connecting shaft. For instance, when the pressure block 31 presses against the contact switch 32 and causes the contact switch 32 to close, the electromagnetic brake is de-energized and the connecting shaft can be locked to prevent the lifting device 20 from excessively lifting and falling and causing a collision. This is beneficial to improving the safety and service life of the frame 100 or the surgical microscope 200. Furthermore, by configuring the first locking unit 33 as an electromagnetic brake, the locking reliability is improved, thereby reducing the risk of locking failure.

[0125] Combination Figure 30 and Figure 31 In some embodiments of the present invention, the lifting drive 22 has an adjustment switch 221, which has an open state and a closed state. In the open state, the length of the lifting drive 22 is adjustable so that the lifting drive 22 can provide driving force to the lifting arm 21, thereby driving the lifting arm 21 to rotate relative to the base 40, so that the lifting arm 21 can drive the surgical microscope 200 to rise and fall through the rotating device 10. In the closed state, the length of the lifting drive 22 is fixed, that is, in the closed state, the lifting drive 22 cannot extend or retract, so that the lifting drive 22 cannot provide driving force to the lifting arm 21 to achieve the positioning of the lifting arm 21. In other words, the lifting arm 21 can be locked by closing the adjustment switch 221 to prevent collisions caused by excessive lifting and falling of the lifting device 20.

[0126] In some embodiments of the present invention, the regulating switch 221 is adapted to selectively switch to the closed state according to the triggering state of the limit unit 30.

[0127] For example, when the rotating device 10 is raised to the limit height, the limiting unit 30 is triggered, and the limiting unit 30 can output a signal and control the adjusting switch 221 to switch to the closed state. At this time, the lifting drive 22 cannot extend or retract, and the lifting drive 22 stops providing driving force to the lifting arm 21. Since the driving force that can drive the lifting arm 21 to rotate relative to the base 40 disappears, the lifting arm 21 cannot further drive the surgical microscope 200 to rotate through the rotating device 10, thereby preventing the lifting device 20 from rising excessively and causing a collision.

[0128] Combination Figure 30 and Figure 31 In some embodiments of the present invention, the first locking component includes an electromagnetic locking mechanism 34, which is disposed on the lifting drive member 22 and is disposed opposite to the adjusting switch 221. The electromagnetic locking mechanism 34 is adapted to selectively press against the adjusting switch 221 according to the triggering state of the limiting unit 30, so that the adjusting switch 221 is selectively closed.

[0129] For example, when the rotating device 10 is raised to the limit height, the limiting unit 30 is triggered. At this time, the limiting unit 30 can output a signal and cause the electromagnetic locking mechanism 34 to press against the adjusting switch 221, so that the adjusting switch 221 is switched to the closed state. At this time, the lifting drive 22 cannot extend or retract, so that the lifting drive 22 stops providing driving force to the lifting arm 21. The lifting arm 21 can be positioned at the current position to prevent the lifting arm 21 from further driving the rotating device 10 to rise, thereby preventing a collision.

[0130] When the height of the surgical microscope 200 needs to be adjusted, the electromagnetic locking mechanism 34 releases the pressure on the adjustment switch 221, and the adjustment switch 221 switches to the open state. At this time, the lifting drive component 22 can extend and retract to provide driving force to the lifting arm 21, thereby driving the lifting arm 21 to rotate. The lifting arm 21 can drive the surgical microscope 200 to rise or fall through the rotating device 10, thereby realizing the adjustment of the height of the surgical microscope 200.

[0131] Combination Figure 30 and Figure 31 In some embodiments of the present invention, the electromagnetic locking mechanism 34 includes a pressing member 341 and a magnetic member 342. The pressing member 341 is rotatably disposed on the lifting drive member 22, and at least a portion of the pressing member 341 is disposed opposite to the adjusting switch 221. The magnetic member 342 can selectively attract the pressing member 341 so that the pressing member 341 presses against the adjusting switch 221.

[0132] For example, the magnetic component 342 can be fixed on the lifting drive component 22, and the pressing component 341 is rotatably disposed at the end of the lifting drive component 22 where the adjusting switch 221 is located, so that the pressing component 341 can be disposed opposite to the adjusting switch 221. The magnetic component 342 is configured to generate magnetic attraction when energized, and the pressing component 341 can be constructed as a ferromagnetic material. Under the action of the magnetic attraction, the pressing component 341 rotates toward the direction closer to the adjusting switch 221, so that the pressing component 341 can press against the adjusting switch 221, so that the adjusting switch 221 switches to the closed state. At this time, the lifting drive component 22 cannot extend or retract, so that the lifting drive component 22 stops providing driving force to the lifting arm 21, and the lifting arm 21 can be positioned at the current position.

[0133] When the limiting unit 30 is triggered, the magnetic component 342 can be energized and attract the pressing component 341, causing the pressing component 341 to press against the adjusting switch 221 and switch to the closed state. In the above technical solution, the magnetic component 342 does not bear the torque of the microscope, and when the pressing component 341 is released from its engagement with the adjusting switch 221, the force acting on the pressing component 341 also disappears. Therefore, the wear of the electromagnetic drive mechanism can be effectively reduced, thereby improving the service life of the electromagnetic drive mechanism and reducing the maintenance frequency of the lifting device 20.

[0134] It should be noted that the aforementioned first locking unit 33 selectively locks the lifting device 20 according to the triggering state of the limiting unit 30, the adjusting switch 221 selectively switches to the closed state according to the triggering state of the limiting unit 30, or the electromagnetic locking mechanism 34 selectively presses against the adjusting switch 221 according to the triggering state of the limiting unit 30. It is emphasized that when the rotating device 10 is raised to the limit position, the limiting unit 30 cooperates with the first locking unit 33, the adjusting switch 221, or the electromagnetic locking mechanism 34 to adjust the opening and closing state of the first locking unit 33, the adjusting switch 221, or the electromagnetic locking mechanism 34. It should not be understood that the first locking unit 33, the adjusting switch 221, or the electromagnetic locking mechanism 34 can only play a locking and positioning role when the rotating device 10 is raised to the limit position.

[0135] When the rotating device 10 is at any height other than the limit height, the first locking unit 33, the adjusting switch 221, or the electromagnetic locking mechanism 34 can also be selectively opened or closed manually or by other electronic control methods to achieve the positioning of the rotating device 10.

[0136] Combination Figures 28 to 31In some embodiments of the present invention, the lifting drive component 22 is provided with a connecting joint 222 at one end of the adjusting switch 221. The lifting drive component 22 is rotatably connected to the base 40 through the connecting joint 222. The connecting joint 222 can avoid the adjusting switch 221. The pressing component 341 is rotatably mounted on the connecting joint 222 through a reset component such as a torsion spring or spring. When the magnetic component 342 attracts the pressing component 341, the pressing component 341 drives the reset component to deform. When the magnetic component 342 is de-energized, the magnetic attraction force it generates on the pressing component 341 disappears, and the pressing component 341 can automatically reset under the action of the reset component.

[0137] like Figure 28 As shown, in some embodiments of the present invention, a slide rod 41 is provided on the base 40. In the upward direction of the lifting device 20, the distance between the slide rod 41 and the rotating device 10 gradually increases. Conversely, in the downward direction of the lifting device 20, the distance between the slide rod 41 and the rotating device 10 in the horizontal direction gradually decreases.

[0138] The lifting drive component 22 is sleeved on the slide rod 41 and is adapted to slide along the slide rod 41. The slide rod 41 can guide and support the lifting drive component 22. The lifting drive component 22 can slide to different positions according to the load it bears. Specifically, the load borne by the lifting drive component 22 can be decomposed into a component force extending along the slide rod 41 and a component force perpendicular to the slide rod 41. By sliding the lifting drive component 22 to different positions of the slide rod 41, the installation angle between the lifting drive component 22 and the slide rod 41 can be adjusted, so that the component force perpendicular to the slide rod 41 (which can also be understood as the supporting force of the slide rod 41 on the lifting drive component 22) can be adapted to different load requirements.

[0139] Combination Figures 20 to 26 In some embodiments of the present invention, the lifting device 20 further includes a second locking component 23, which is respectively disposed on the first support arm 213 and the second support arm 214 and is used to lock the first support arm 213 and the second support arm 214. By using the second locking component 23 to lock the first support arm 213 and the second support arm 214, the risk of the lifting device 20 being raised or lowered under external force or its own weight due to the failure of the first locking component during transportation of the frame 100 equipped with the surgical microscope 200 is prevented. This improves the stability of the lifting device 20 during transportation and reduces the risk of damage to the surgical microscope 200 due to collision.

[0140] Combination Figures 20 to 26In some embodiments of the present invention, the second locking assembly 23 includes: a first locking engagement portion 231, a second engagement portion, and a locking member 233. The first locking engagement portion 231 is disposed on the first support arm 213, and the second locking engagement portion 232 is disposed on the second support arm 214. At least a portion of the locking member 233 is movably disposed on the first locking engagement portion 231 or the second locking engagement portion 232, and the locking member 233 can pass through the first locking engagement portion 231 and the second locking engagement portion 232 to lock the first support arm 213 and the second support arm 214.

[0141] For example, the first locking engagement portion 231 may be disposed on the side of the first support arm 213 facing the second support arm 214, and the first locking engagement portion 231 may extend in the direction of the second support arm 214. The second locking engagement portion 232 may be disposed on the side of the second support arm 214 facing the first support arm 213, and the second locking engagement portion 232 may extend in the direction of the first support arm 213.

[0142] When the lifting device 20 is in a roughly horizontal position, the first locking engagement part 231 and the second locking engagement part 232 can face each other in a direction parallel to the fourth axis. The locking member 233 can move to the position where it passes through the first locking engagement part 231 and the second locking engagement part 232 respectively, so as to lock the first support arm 213 and the second support arm 214. At this time, neither the first support arm 213 nor the second support arm 214 can rotate relative to the rotating device 10 and the base 40, so as to prevent the lifting device 20 from rising or falling.

[0143] When the surgical microscope 200 needs to be raised or lowered via the lifting device 20, the locking member 233 can be driven to disengage from at least one of the first locking engagement part 231 and the second locking engagement part 232. At this time, the first arm 213 and the second arm 214 can rotate relative to the rotating device 10 and the base 40. The lifting drive member 22 can drive the first arm 213 to rotate around the fourth axis, and the first arm 213 drives the second arm 214 to rotate synchronously. Thus, the lifting drive member 22 can drive the lifting arm 21 and drive the rotating device 10 to rise or fall, thereby adjusting the height of the surgical microscope 200.

[0144] In some specific embodiments, both the first locking engagement portion 231 and the second locking engagement portion 232 are configured as locking plates, and both the first locking engagement portion 231 and the second locking engagement portion 232 are formed with locking holes that pass through them in an axial direction parallel to the outer casing 2331. At least a portion of the locking member 233 can pass through the locking holes on the first locking engagement portion 231 and the second locking engagement portion 232 respectively to lock the first locking engagement portion 231 and the second locking engagement portion 232.

[0145] Combination Figure 21 , Figure 22 , Figures 32 to 34 In some embodiments of the present invention, the locking member 233 includes: a housing 2331, a locking pin 2332, and an elastic member 2333. The housing 2331 is fixedly disposed on the side of the second locking engagement portion 232 opposite to the first locking engagement portion 231. At least a portion of the locking pin 2332 is inserted into the housing 2331, and the locking pin 2332 can slide relative to the housing 2331 in a direction parallel to the fourth axis. The elastic member 2333 is elastically supported between the locking pin 2332 and the housing 2331. The elastic member 2333 is adapted to drive the locking pin 2332 through the first locking engagement portion 231 and the second locking engagement portion 232.

[0146] For example, the housing 2331 can be used to support the locking pin 2332 to improve the assembly reliability of the locking pin 2332 and reduce the risk of the locking pin 2332 falling off. The elastic member 2333 can be elastically supported between the side wall of the housing 2331 opposite to the second locking engagement part 232 and the locking pin 2332. When the locking pin 2332 disengages from the first locking engagement part 231, the locking pin 2332 drives the elastic member 2333 to deform. When it is necessary to engage the locking pin 2332 with the first locking engagement part 231, the locking pin 2332 can release the elastic member 2333, and the locking pin 2332 can pass through the first locking engagement part 231 under the drive of the elastic member 2333, so that the locking pin 2332 can lock the first locking engagement part 231 and the second locking engagement part 232 again.

[0147] Therefore, by setting the elastic element 2333, it is beneficial to improve the driving convenience of the locking pin 2332 and reduce the operational difficulty when the locking element 233 locks the first locking engagement part 231 and the second locking engagement part 232.

[0148] Combination Figure 33 and Figure 34 In some embodiments of the present invention, the locking pin 2332 is provided with a limiting pin 2334 arranged in its radial direction, and the outer shell 2331 is provided with a limiting groove 2335 extending in the circumferential direction of the outer shell 2331. The limiting pin 2334 slides with the limiting groove 2335 and extends out of the outer shell 2331 through the limiting groove 2335. The limiting pin 2334 is adapted to abut against the groove wall of the limiting groove 2335 to position the locking pin 2332 at a position disengaged from the first locking engagement part 231.

[0149] For example, to prevent the locking pin 2332 from sliding again towards the first locking engagement part 231 after disengaging from the elastic element 2333, it is necessary to position the locking pin 2332 to maintain the state in which the locking pin 2332 presses and deforms the elastic element 2333. Therefore, a limiting groove 2335 can be provided on the housing, and a limiting pin 2334 can be provided on the locking pin 2332. The limiting pin 2334 can be fixedly connected to the locking pin 2332. When pin 2332 slides to the position where it disengages from the first locking engagement part 231, in the direction in which the elastic member 2333 recovers its deformation, the limiting pin 2334 can engage with the groove wall of the limiting groove 2335 to position the locking pin 2332 at the position where it disengages from the first locking engagement part 231. This ensures that after the locking pin 2332 disengages from the first locking engagement part 231, it can maintain the state of pressing and deforming the elastic member 2333, making it easier for the elastic member 2333 to drive the locking pin 2332 again.

[0150] like Figure 34 As shown, in some embodiments of the present invention, the limiting groove 2335 includes: a first groove segment a and a second groove segment b. The first groove segment a extends spirally along the circumferential direction of the outer shell 2331, and the second groove segment b is connected to the first groove segment a. The second groove segment b is recessed in the direction close to the first locking mating part 231 along the axial direction of the locking member 233.

[0151] For example, since the locking pin 2332 needs to slide in a direction parallel to the fourth axis during the selective locking engagement with the first locking engagement part 231, in order to prevent the limiting pin 2334 from interfering with the sliding of the locking pin 2332 in the direction parallel to the fourth axis, the first groove segment a can be spirally extended in the circumferential direction of the outer shell 2331. When the limiting pin 2334 slides in the first groove segment a, the locking pin 2332 can slide in a direction parallel to the fourth axis, so that the locking pin 2332 can disengage from the first locking engagement part 231 or pass through the first locking engagement part 231, thereby achieving selective locking of the first locking engagement part 231 and the second locking engagement part 232.

[0152] When the limiting pin 2334 slides from the first groove a to the second groove b, the limiting pin 2334 can be embedded in the second groove b. The limiting pin 2334 can not only stop and cooperate with the groove wall of the second groove b near the first locking engagement part 231, but also stop with the groove wall of the second groove b opposite to the groove wall in the circumferential direction of the outer shell 2331, so that the second groove b can play the role of limiting the limiting pin 2334, thereby realizing the positioning of the locking pin 2332.

[0153] In the above technical solution, the limiting pin 2334 extends out of the housing through the limiting groove 2335. The locking pin 2332 can be slid relative to the housing by driving the limiting pin 2334, so as to selectively lock the first locking engagement part 231 and the second locking engagement part 232; or, the limiting pin 2334 can be moved relative to the housing by driving the locking pin 2332, so as to selectively lock the first locking engagement part 231 and the second locking engagement part 232.

[0154] Reference Figure 34 In some embodiments of the present invention, the locking member 233 further includes a driving part 2336, which is disposed at the end of the locking pin 2332 away from the first locking engagement part 231 and located on the outside of the housing 2331. The driving part 2336 is used to drive the locking pin 2332 to slide relative to the housing 2331, and the engagement state of the locking pin 2332 and the first locking engagement part 231 can be identified by the driving part 2336.

[0155] For example, in the radial direction parallel to the locking pin 2332, both sides of the driving part 2336 may protrude from the locking pin 2332 to facilitate the user's grip on the driving part 2336, thereby facilitating the sliding of the locking pin 2332 relative to the housing 2331 by the driving part 2336. Furthermore, the portion of the driving part 2336 protruding from the locking pin 2332 may be parallel to or perpendicular to the axial direction of the limiting pin 2334, so as to determine whether the limiting pin 2334 is located in the second groove segment b based on the rotation angle of the driving part 2336, thereby facilitating the identification of the engagement state between the locking pin 2332 and the first locking engagement part 231 based on the driving part 2336.

[0156] Combination Figure 1 , Figure 37 and Figure 38 According to an embodiment of the present invention, a surgical microscope system 1000 includes: a surgical microscope 200, an equipment integration cabinet 300, and a frame 100. The equipment integration cabinet 300 is provided with at least a display 310, which is electrically connected to the surgical microscope 200 and used to display images provided by the surgical microscope 200. The frame 100 is connected to the equipment integration cabinet 300 and the surgical microscope 200 respectively, and is used to adjust the position of the surgical microscope 200.

[0157] For example, the equipment integration cabinet 300 can serve as the mounting carrier for the rack 100, and can support the rack 100. The equipment integration cabinet 300 is equipped with a display 310, which is electrically connected to the microscope camera device 210 of the surgical microscope 200. The images acquired by the microscope camera device 210 can be transmitted to the display 310, so that the user can observe them through the display 310.

[0158] According to an embodiment of the present invention, the surgical microscope system 1000 adopts the aforementioned frame 100. The frame 100 is equipped with a rotating device 10 including a first drive motor 13, a rotating arm 14, and a transmission mechanism 15. The transmission mechanism 15 is connected to at least the first drive motor 13, the rotating arm 14, and the surgical microscope 200. This allows the first drive motor 13 to drive the rotating arm 14 to rise and fall and the surgical microscope 200 to rotate via the transmission mechanism 15. This not only allows for adjustment of the height of the surgical microscope 200 but also for adjustment of the rotation angle of the surgical microscope 200 to meet different user needs and improve the user experience.

[0159] like Figure 37 As shown, in some embodiments of the present invention, the lifting device 20 is rotatably connected to the equipment integration cabinet 300 via a rotating shaft, and a large pulley is coaxially connected to the rotating shaft of the lifting device 20. The surgical microscope system 1000 also includes a third locking unit, which is used to selectively lock the rotating shaft of the lifting device 20. A small pulley is provided on the output shaft of the third locking unit, and the large pulley and the small pulley are connected by a belt drive. The third locking unit is configured as an electromagnetic brake.

[0160] In the above technical solution, by setting a pulley transmission mechanism between the electromagnetic brake and the rotating shaft of the lifting device 20, the torque of the electromagnetic brake can be amplified and transmitted to the rotating shaft of the lifting device. This is beneficial to the miniaturization design of the electromagnetic brake, thereby reducing the volume of the surgical microscope system 1000 and reducing the cost of the surgical microscope system 1000.

[0161] It is understandable that the pulleys mentioned above can also be configured as gears or other transmission components. The specific configuration can be selected according to actual production requirements, and no specific limitations are made here.
