On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0029] Reference below Figure 1-6 , the implementation of the lens capsule polisher proposed in accordance with an embodiment of the utility model is described in detail.
[0030] The lens capsule polisher according to the embodiment of the utility model comprises: a handle 1 and a polishing part 2 .
[0031] Specifically, the handle 1 has a first part 11 and a second part 12, and the first part 11 and the second part 12 are connected in a manner that can rotate relative to each other around the axis of the handle 1; the polishing part 2 has a scraping edge 21 and a connecting part 22, the scraping edge 21 is installed on the connecting part 22, and the connecting part 22 is swingably connected to the first part 11.
[0032] That is to say, the connecting part 22 is swingably connected to the first part 11, so that the angle of the connecting part 22 can be swingably adjusted, and the first part 11 and the second part 12 of the handle 1 are rotatably connected, so that the connecting part 22 has both a swinging function and a rotation function relative to the second part 12, thereby facilitating the rotation and turning over of the scraping edge 21 and the adjustment of the angle, and then facilitating the scraping edge 21 to perform all-round polishing of the anterior capsule and the posterior capsule of the lens, which has the advantages of high efficiency, safety, convenience, etc., can avoid damage to intraocular tissues and reduce complications.
[0033] Thus, the connection part 22 of the polishing part 2 is swingably connected to the first part 11 of the handle 1, so that the scraping edge 21 on the connection part 22 can swing relative to the handle 1, and the first part 11 and the second part 12 of the handle 1 can be relatively rotatably connected, so that the scraping edge 21 can rotate relative to the second part 12, so that the scraping edge 21 can both swing and rotate, and it is convenient for the scraping edge 21 to adjust different angles and directions to polish the anterior capsule and the posterior capsule of the lens. The lens capsule polisher has a simple structure and can perform all-round polishing on the anterior capsule and the posterior capsule of the lens.
[0034] Regarding the connection between the scraping edge 21 and the connecting portion 22, the scraping edge 21 and the connecting portion 22 are detachably connected. It can be understood that the detachable connection between the scraping edge 21 and the connecting portion 22 facilitates the replacement of the scraping edge 21. The scraping edge 21 can be connected to the connecting portion 22 by threaded connection or plug-in connection.
[0035] As for the outer contour of the scraping edge 21, the scraping edge 21 is in an arc shape, the arc length of the scraping edge 21 is 2mm-4mm, the edge width is 0.5mm-1mm, and the edge height is 0.5mm-1.5mm. It can be understood that by setting the arc length of the scraping edge 21 to 2mm-4mm, the arc length of the scraping edge 21 is smaller than the radius of the lens capsule, which not only ensures the flexibility of the scraping edge 21 in the capsule, but also ensures that there is enough contact area to ensure polishing efficiency and safety; by setting the edge width of the scraping edge 21 to 0.5mm-1mm, it can be ensured that the scraping edge 21 has enough contact area to ensure polishing efficiency; by setting the edge height of the scraping edge 21 to 0.5mm-1.5mm, it is convenient for the scraping edge 21 to enter the eye through a corneal incision less than 2mm, meeting the requirements of minimally invasive surgery.
[0036] As for the second part 12, the second part 12 is provided with a plurality of annular grooves 121. It can be understood that by providing a plurality of annular grooves 121, the friction between the palm or fingers can be increased, and the grip can be more firmly during use. Among them, the second part 12 can be cylindrical.
[0037] Regarding the size of the handle 1, the length of the handle 1 is 5 cm-15 cm. It can be understood that by setting the length of the handle 1 to 5 cm-15 cm, it is convenient for the user to better hold the handle 1 with one hand for use under the surgical microscope, and the specific length can be set according to actual conditions.
[0038] For the connection between the first part 11 and the second part 12, the first part 11 is provided with an insertion shaft 111, and the second part 12 is provided with a socket 122. The insertion shaft 111 is inserted into the socket 122 in a manner that it can rotate relative to its axis. It can be understood that the connection between the first part 11 and the second part 12 is facilitated by the cooperation between the insertion shaft 111 and the socket 122, and the relative rotation function of the first part 11 and the second part 12 is realized. Among them, the insertion shaft 111 and the socket 122 can be connected by the cooperation of a rib and a groove or a buckle and a slot.
[0039] For the plug shaft 111 and the plug hole 122, the plug shaft 111 and the plug hole 122 are damped. It can be understood that the plug shaft 111 and the plug hole 122 are damped, which can facilitate the scraping edge 21 to rotate and maintain after the angle, thereby preventing the scraping edge 21 from being displaced during polishing. Among them, the plug shaft 111 and the plug hole 122 can be made of damping material, or a damping member can be provided between the plug hole 122 and the plug shaft 111.
[0040] For the connection between the connecting portion 22 and the first portion 11, the first portion 11 defines a first connecting hole 113, the connecting portion 22 defines a second connecting hole 221, and the first connecting hole 113 and the second connecting hole 221 are connected through a connecting member 13. It can be understood that the first connecting hole 113 and the second connecting hole 221 can be easily connected by the connecting member 13, thereby facilitating the connection between the first portion 11 and the connecting portion 22, so that the connecting portion 22 can swing relative to the first portion 11. The connecting member 13 can be a pin or a threaded screw.
[0041] Regarding the connection between the connecting portion 22 and the first portion 11, the first portion 11 defines a connecting groove 112, a first connecting hole 113 is provided on both sides of the connecting groove 112, and the second connecting hole 221 is located between the two first connecting holes 113. It can be understood that by the second connecting hole 221 being located between the two first connecting holes 113, one end of the connecting portion 22 can swing in the connecting groove 112 with the connecting member as a fulcrum, and at the same time, it is convenient to restrict the connecting portion 22 to swing in the connecting groove 112, so that the scraping edge 21 is not easy to deviate after adjusting the angle, and the structure is more stable. Among them, a damping member can be provided between the first connecting hole 113 and the second connecting hole 221 to facilitate maintaining the adjusted angle of the scraping edge 21.
