[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Combination Figure 1-4 As shown, an ophthalmic surgical needle storage device comprises:

[0025] The housing 1 is a cylindrical structure, and a plurality of through holes 12 are formed on its side wall to protect the needle and support and fix the internal components;

[0026] The positioning block 2 is slidably mounted inside the housing 1, and a plurality of needle holes 21 are provided on its side wall and aligned with the through hole 12, and is mainly used for placing needles;

[0027] The fixing seat 3 is rotatably mounted on the bottom of the housing 1 and is in transmission connection with the positioning block 2. By rotating, the positioning block 2 can be driven to approach or move away from the inner wall of the housing 1, so that the needle part on the positioning block 2 extends to the outside of the housing 1 for easy access;

[0028] The shielding sleeve 4 is arranged on the top of the shell 1 and is slidably inserted into the shell 1. It can be riveted to the shell 1 through a threaded structure, so that when not in use, it shields the through hole 12 on the surface of the shell 1, isolates the connection between the needle and the outside world, and plays a certain protective role.

[0029] Specifically, four slide grooves 11 are provided on the inner bottom surface of the shell 1, and the four slide grooves 11 all penetrate the bottom surface of the shell 1, and two positioning blocks 2 are movably installed inside each slide groove 11, and the four positioning blocks 2 are arranged in a circular array around the center of the bottom surface of the shell 1.

[0030] In this structure, the positioning block 2 should adopt an arc-shaped outer wall close to the arc of the inner wall of the shell 1, and the needle hole 21 is set on the arc-shaped outer wall, so that the needle hole 21 is aligned with the through hole 12, and the needle handle of the needle can be freely inserted into the through hole 12.

[0031] Based on the above structure, in this embodiment, the shell 1 can also be directly set as a rectangular box structure, and the side wall of the positioning hole facing outward is simultaneously set as a rectangular surface, and the pinholes 21 are arranged in a rectangular array on the rectangular surface.

[0032] An adjusting disk 31 is provided on the top surface of the fixing seat 3, and an adjusting groove 32 is provided on the top surface of the adjusting disk 31. The adjusting groove 32 is a spiral groove starting from the center of the adjusting disk 31 and gradually opening outward. Therefore, the top part of the positioning block 2 protrudes downward and is inserted into the adjusting groove 32. In the process of driving the adjusting groove 32, the arc-shaped inner wall can be used to drive the four positioning blocks 2 to synchronously move away from or close to the center of the bottom surface of the shell 1, and cooperate with the needle hole 21 in the above structure to realize the contraction and expansion of the needle.

[0033] In addition, in order to ensure that the above structure can rotate flexibly, an annular bearing 13 should be arranged between the top of the fixing seat 3 and the bottom of the shell 1 to ensure flexibility. At the same time, elastic friction plates are arranged on both sides of the fixing seat 3 to fix the shell 1 on the top of the fixing seat 3 when rotation is not required.

[0034] The top end of the shell 1 is opened and extends inward at the opening to form a stepped structure, and the shielding sleeve 4 is slidably inserted into the shell 1 and provided with a connector 41 at its bottom. The outer diameter of the connector 41 is larger than the inner diameter of the stepped structure, so the connector 41 will be stuck in the shell 1 and cannot be pulled out.

[0035] Matching threaded structures are provided on the side walls of the connector 41 and the inner walls of the top and bottom ends of the shell 1, wherein the thread on the inside of the top end of the shell 1 should be located below the stepped structure. Therefore, in actual use, the entire shielding sleeve 4 can determine whether to block the through hole 12 on the shell 1 through the fixed position of the connector 41.

[0036] A placement box 42 is also provided on the top of the shielding sleeve 4. The outer diameter of the placement box 42 is the same as the outer diameter of the shell 1. When the bottom surface of the placement box 42 is in contact with the top of the shell 1, the connector 41 is riveted to the thread at the bottom of the shell 1. At the same time, the interior of the placement box 42 is divided into four spaces of equal size by a cross-shaped partition for storing some auxiliary components.

[0037] A cavity should also be provided inside the positioning block 2, and the cavity is arranged toward the center of the shell 1, and an opening is provided on the top surface of the cavity, through which medical cotton is filled into the cavity, so that the needle in the needle hole 21 can be inserted into the medical cotton, thereby acting as a buffer layer. At the same time, a long strip installation groove is provided on the inner wall of the needle hole 21 of the positioning block 2 along the extension direction of the needle hole 21, and a soft magnetic plate is provided in the installation groove. The soft magnetic plate is made of magnetic rubber material, and the needle will be adsorbed and fixed by the soft magnetic plate when inside.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
