[0001] The invention relates to the field of ophthalmic treatment, and in particular to an ophthalmic laser treatment system. Background Art

[0002] In ophthalmic laser treatment, a laser treatment device for producing incisions in the eye tissue by means of a laser beam or for ablating or for coagulating the eye tissue is often combined with an examination device, either by integrating them into a common system or by installing the examination device in the vicinity of the laser treatment device so that switching between the two devices can be carried out without placing the patient in another room;

[0003] However, the existing ophthalmic laser treatment system requires the alternating use of inspection equipment and laser treatment equipment. In this process, the relative position between the laser treatment equipment and the patient will change, and repositioning is required. Repositioning requires high technical costs to achieve a large range of movement, and also requires a larger space. The system size of the non-integrated laser device and inspection device is relatively large. Summary of the invention

[0025] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0026] Embodiment 1

[0027] like Figures 1 to 3 As shown, an ophthalmic laser treatment system provided by an embodiment of the present invention comprises two coaxially arranged working arms and a base 3, both of which are rotatably mounted on the base 3, and a cavity is provided in the base 3, in which an adjustment mechanism for driving one of the working arms to rotate or driving both working arms to rotate simultaneously is provided;

[0028] The two working arms of the present embodiment are respectively a laser arm 1 and a microscope arm 2. The laser arm 1 and the microscope arm 2 both include a working portion and a connecting portion. The connecting portion of the laser arm 1 is coaxial with the connecting portion of the microscope arm 2. The working portion of the laser arm 1 of the present embodiment is located below the working portion of the microscope. Of course, the positions can also be interchanged. The connecting portion of the laser arm 1 is provided with a receiving groove capable of receiving the connecting portion of the microscope arm 2, so that the connecting portion of the microscope arm 2 can extend into the base 3.

[0029] In this embodiment, both working arms are mounted on the base 3 through the bearing seat 4, specifically the upper wall of the cavity and the lower arm of the cavity. This is an existing installation method, so it will not be repeated here;

[0030] The adjusting mechanism includes a driving mechanism and a linkage mechanism. The driving mechanism includes a driving unit 16. The driving unit 16 of this embodiment uses a motor, which is fixedly installed on the inner wall of the cavity. The output shaft of the driving unit 16 is connected to one of the working arms (laser arm 1) through a transmission mechanism. The linkage mechanism is fixedly installed on the other working arm (microscope wall). The linkage mechanism includes a driving unit 2 12 and a connector. The driving unit 2 13 uses a cylinder / oil cylinder. The working arm (laser arm 1) connected to the output shaft of the driving unit 16 is provided with a card slot 15 that matches the connector. The second driving unit 12 can drive the connector to be inserted into the card slot 15 to realize the connection of the two working arms. After the two working arms are connected, the driving mechanism can drive the two working arms to rotate simultaneously to reach the treatment position. When the treatment is completed, the connection between the two working arms is disconnected through the linkage mechanism, and the laser arm 1 can be moved away through the driving mechanism, and then the microscope arm 2 is used for inspection. After the inspection, the laser arm 1 is reset through the driving mechanism. After the linkage mechanism determines that the laser arm 1 is accurately reset, the treatment can be performed again, without the need for cumbersome positioning steps, which is more convenient and effectively shortens the treatment time.

[0031] Embodiment 2

[0032] This embodiment discloses an ophthalmic laser treatment system based on the first embodiment, wherein the connector comprises a connection seat 13 connected to the second drive unit 12 and a plurality of plug rods 14 mounted on the connection seat 13, the connection seat 13 is sleeved on the microscope arm 2 and is not fixedly connected thereto, an ear plate 5 is mounted on the working arm corresponding to the connector, and a plurality of card slots 15 corresponding to the plurality of plug rods 14 are provided on the ear plate 5;

[0033] like Figure 6 As shown, the multiple insertion rods 14 of this embodiment are evenly distributed along the circumference of the working arm, and the outer diameters of the multiple insertion rods 14 are increased and the lengths are decreased in sequence, while the size of the slots 15 remains unchanged. When docking, the thinnest insertion rod 14 is first inserted into the corresponding slot 15, and the remaining insertion rods 14 are inserted into the corresponding slots 15 in sequence, which has a certain anti-drift effect and reduces the influence of wear of the driving mechanism after long-term use on the reset accuracy of the laser arm 1;

[0034] In some other embodiments, the top end of the insertion rod 14 is designed to be a cone-shaped structure.

[0035] Embodiment 3

[0036] like Figure 1-Figure 6As shown, this embodiment discloses an ophthalmic laser treatment system based on the second embodiment. Since the microscope arm 2 is located in the laser arm 1 and its shape is 7-shaped, the center of gravity is offset. During the movement of the laser arm 1, the position of the microscope arm 2 will be affected. To avoid this effect, this embodiment adopts a method of fixing the microscope arm 2 while the laser arm 1 moves, as follows:

[0037] The transmission mechanism includes a gear 7, a gear ring 8, and a matching mechanism for driving the gear 7 to move axially. The gear 7 is splined to the output shaft of the driving unit 6, and the gear ring 8 is fixedly connected to the working arm. Under the action of the matching mechanism, the gear 7 can be meshed and connected with the gear ring 8. The connecting seat 13 is located on the moving path of the mounting seat 10. When the gear 7 is meshed and connected with the gear ring 8, the mounting seat 10 can contact the connecting seat 13 (when the mechanical arm is not linked with the microscope arm 2). Since the linkage mechanism is fixedly connected with the microscope arm 2, it is equivalent to fixing the microscope arm 2 (such as Figure 4 As shown, when the laser arm 1 rotates, the position of the microscope arm 2 will not be affected. During inspection, it is also effective to prevent the position from changing due to touching the microscope arm 2, which affects the subsequent reset of the laser arm 1. After the laser arm 1 is reset, the drive unit 2 12 drives the insertion rod 14 to be inserted into the card slot 15 to complete the linkage between the two. During this process, the connecting seat 13 rises and separates from the mounting seat 10 (as shown in FIG. Figure 5 As shown), the microscope arm 2 is unlocked while the two working arms are linked, which facilitates the subsequent synchronous adjustment of the two arms;

[0038] Specifically, the matching mechanism of the present embodiment includes a mounting seat 10 and a driving unit three 9. The driving unit three 9 is installed in the base 3, and its output end is connected to the mounting seat 10. The driving unit three 9 of the present embodiment uses a cylinder / hydraulic cylinder. A slewing bearing 11 is installed on the mounting seat 10. The slewing bearing 11 is located on the lower side of the gear 7 and plays a role in supporting the gear 7. When the driving unit 16 drives the gear 7 to rotate, the matching mechanism will not affect the rotation of the gear 7. In addition, two slewing bearings 11 located on the upper and lower sides of the gear 7 can be installed on the mounting seat 10. Correspondingly, the mounting seat 10 needs to extend an additional part to support the slewing bearing 11 located on the upper side of the gear 7. In addition, in order to avoid hard contact, a plurality of positioning rods can be installed on the mounting seat 10, and a plurality of ear plates 5 are installed on the slewing bearing 11. The ear plates 5 are provided with through holes that cooperate with the positioning rods. A spring is placed between the slewing support and the mounting seat 10, thereby reducing the hard collision between the gear 7 and the ring gear 8 and improving the service life.
