New description: [New technical field] The present invention relates to a picking device, in particular to a corneal picking device. [Prior Art] Refer to Figure 1, the existing corneal extraction device! The utility model comprises an outer cylinder u, a ring ore 12 which is movably disposed on the outer 胄u+, and a plurality of blocks 13 which are arranged on the outer peripheral surface of the scorpion u and are generally triangular. The outer cylinder 11 has an inner peripheral surface ι 2 formed with an internal thread ι, and a through hole 113 defined by the inner circumferential surface 112; the circular saw 12 has a ring cutting edge capable of penetrating the through hole 113 12 and an external thread 122 formed on the surface in cooperation with the internal thread in. In practical application, the ring saw 12 is rotated, so that the ring cutting edge 121 can protrude the through hole ιΐ3 and the block 13 by using the matching inner and outer threads (1), 122, and then picking the cornea The picking device 1 is placed on a cornea 100, and the card 13 is used to abut the surface of the corner 胄1〇〇, so that the ring cutter 121 can cut into the cornea 1 to form a mouth η, and then Others use the incision to deepen the incision to gradually remove the cornea 100 cut by the circular cutting edge 2', which is not only inconvenient to use, but also easily breaks the flatness of the incision η. Therefore, how to make the operation of removing the cornea 1 更为 is more convenient and rapid, and the damage of the incision can be avoided at the same time, so as to maintain the flatness of the incision, which becomes the primary problem that the corneal extraction operation needs to overcome. [New content] 3 Therefore, the purpose of the present invention is to provide a corneal extraction device that performs the circumcision and extraction operations in one go. Thus, the present corneal extraction device is used for circumcision of a cornea, the corneal extraction device comprising a base, a ring saw movably disposed on the base, and a picking pivoted on the ring saw unit. The ring ore includes a body portion surrounding the extraction space and reciprocating on the base, a ring edge portion formed at one end of the body for circumcising the cornea, and a body formed on the body a receiving groove that is connected to the extraction space. The S-hai picking unit includes two driving rods correspondingly disposed in the body portion along the length direction of the body portion of the ring saw, and two slits respectively connected to one end of each of the driving rods facing the ring-shaped blade portion blade. The driving rod can drive each of the blades to move between a receiving position and a picking position, and when in the receiving position, the cutting edge is received in the receiving groove, and when the picking is in the picking In the material, the cutting edge protrudes from the receiving groove and is located in the picking space. The utility model has the beneficial effects that: after the ring mine completes the circumcision operation of the cornea, the cutting edge of the extracting piece is moved from the accommodating position to the picking position for corneal picking operation' Cutting and picking the cornea's 'energy-gas-making' without the need to replace other utensils, not only makes the cornea picking operation more convenient and rapid, but also maintains the flatness of the incision. [Embodiment] Points and Effects, in the description, the above-mentioned and other technical contents of the present invention, and the detailed description of the two preferred embodiments of the present preferred embodiment, M434579, will be clearly presented. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 2, a preferred embodiment of the present corneal extraction device 2 includes a base 21, a ring saw movably disposed on the base 21, and a pick-up pivoting on the ring saw 22. Unit 24. The base 21 includes an opposite first end 211 and a second end us, a through portion 213 extending straight through the first end 211 and the second end 212, and a base formed on the through portion 213 Thread 214. The ring saw 22 includes a body portion 221 that is movably inserted into the through portion of the base 21 and defines a picking space 222. The body portion 221 is oriented toward the first end 211. An annular extending portion 223 formed on the main body portion 221 and communicating with the extraction space 222, and a ring-shaped receiving groove 224 formed on the main body portion 221 and the internal thread 214 of the base Cooperating ring saw external thread 225. The picking unit 24 has two driving rods 241 correspondingly disposed in the main body portion 221 of the ring saw 22 along the length direction of the base 21, and two connected to each of the driving rods 241 facing the ring portion A cutting edge 244 on one end of the 223. Each of the driving rods 241 has a connecting end 242 connecting the cutting edge 244, and a driving end 243 opposite to the connecting end 242 and projecting the body portion 222 and the second end 212 of the base 21. When used in a continuous manner, 'the body portion 221 of the ring ore 22 is rotated so that the % blade portion 223 of the ring record 22 can be coupled with the internal thread 214 of the base 5 M434579 by the mating ring outer thread 225 Move between standby positions. The illustrated circumscribed position, as shown in FIG. 2, FIG. 3, 4', when the ring knife portion 223 is in the tangential position, the HI blade portion 223 protrudes from the first portion of the pedestal 21. End 2 ιι cut a cornea 200 ' At this time, the first end 211 of the base 21 can be touched to the cornea 2 〇〇 to provide feedback force i 'read high for corneal circumcision when cutting depth The degree of perception 'causes the ring cutter 223 to form a slot 201 having a predetermined depth of cut on the cornea 2' to avoid overcutting. Referring to FIGS. 3 and 4, when the ring cutter portion 223 forms the slit 2 (H|) on the cornea 200, the driving rod 241 can be driven to interlock with each of the substantially curved cutting edges 244 as shown in FIG. The accommodating position is moved to the picking position as shown in Fig. 6. Referring to Figures 5 and 6, and referring back to Figure 4, when in the accommodating position, the cutting edge 244 is to accommodate the accommodating # (10) order, and when in the picking position, the cutting edge 244 protrudes from the receiving groove 224, and goes deep along the slit 2〇1 to gradually extract the cornea, which is convenient and not convenient. The flatness of the slit 201 is broken. Referring to Fig. 7', the second preferred embodiment of the novel corneal picking device 2 is substantially similar to the first preferred embodiment in that the base 21 is located there. The extraction space 222 includes a base external thread 215, and the ring ore 22 further includes a ring saw internal thread 226 formed on the body portion 221 and engaging with the external thread 215. The example is substantially the same as the first preferred embodiment, and therefore, in addition to achieving the effect of the fourth preferred embodiment, the M434579 also provides - In view of the above, the corneal extraction device 2 of the present invention utilizes a matching ring error 23 and a picking unit 24 pivotally mounted on the rib 23 to cut and pick the cornea. The operation can be done in a timely manner, which not only makes the picking operation of the cornea 2 更为 more convenient and rapid, but also can maintain the smoothness of the incision because the circumcision and the extraction can be performed without the need to replace other utensils. The first end 2U of the mating base η can also contact the cornea 2〇〇 to provide a feedback force, and the degree of perception of the depth of cut during the thin ring cutting operation of the film causes the ring edge portion 223 to form on the cornea 200. A slot 2〇1 having a predetermined depth of cut is effective to avoid the occurrence of (4), so the purpose of (4) can be achieved. However, the above description is only a preferred embodiment of the present invention, and cannot be limited thereto. The scope of the present invention, that is, the simple equivalent changes and modifications made by the present invention in accordance with the scope of the novel application and the novel description are still within the scope of the present patent.
