Description

Technical Field

[0001] This utility model relates to the field of ophthalmic surgical instruments, specifically to an incision retractor for small incision cataract surgery. Background Technology

[0002] Specialized surgical hooks are required for ophthalmic surgical incisions. Currently, ophthalmic surgical incision hooks are generally manufactured by punching out a blank from a single sheet of stainless steel, followed by bending, grinding, polishing, and patterning. Because the hooks are supported by a single piece of material, the overall strength performance is good. However, this manufacturing process consumes a large amount of steel and generates a large amount of scrap material that needs to be recycled. Therefore, the manufacturing process needs to be optimized. Utility Model Content

[0003] The technical problem to be solved: The existing one-piece stamping manufacturing process for eye surgery incision hooks consumes a large amount of steel and generates a large amount of scrap material during the production process.

[0004] To address the shortcomings of existing technologies, this invention provides an incision retractor for small-incision cataract surgery, which solves the problems mentioned in the background art.

[0005] Technical solution:

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cataract small incision surgery incision hook includes a handle, a hook shank, and a hook. The handle, hook shank, and hook are connected by a bent stainless steel strip. The hook shank is located between the handle and the hook, and the two steel strips constituting the handle and hook shank are parallel to each other. The structure of the hook is as follows: the two steel strips at the end of the hook shank away from the handle are bent at right angles to both sides, then bent at right angles downwards, and then bent at right angles towards the handle, and then connected and closed in an arc shape.

[0008] In one possible implementation, the handle is wider than the hook shank, and there is a smooth transition between the handle and the hook shank.

[0009] In one possible implementation, a first support bar is clamped between the two steel wires of the handle, and a first stainless steel sleeve is fixedly fitted onto the outside of the handle.

[0010] In one possible implementation, a second support bar is clamped between the two steel wires of the hook handle, and a second stainless steel sleeve is fixedly fitted onto the outside of the hook handle.

[0011] In one possible implementation, the outer wall of the first sleeve is provided with anti-slip texture along its width direction, and the anti-slip texture is uniformly distributed along the length direction of the first sleeve.

[0012] In one possible implementation, the end of the handle away from the hook is set as a weld point for a stainless steel strip.

[0013] Beneficial effects: The main body of the device is made by bending a section of stainless steel strip, and then the support strip is inserted into the handle 1 and hook 2 and tightened and fixed by the sleeve interference fit. Compared with the steel plate die stamping process, the device has a simple and readily available structure, is lightweight and easy to operate, and has very little processing loss and processing waste. It effectively solves the problem that the existing ophthalmic surgical incision hook integrated stamping manufacturing process consumes a lot of steel and generates a lot of scrap during the production process.

[0021] The technical solution of the invention will now be clearly and completely described in conjunction with the accompanying drawings. In the description of the invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, not to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying their relative importance.

[0022] This application provides an incision retractor for small-incision cataract surgery, which solves the problems in the prior art.

[0023] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0024] The specific structure of this embodiment is as follows: Figures 1-4 A cataract small incision surgery incision hook includes a handle 1, a hook shank 2, and a hook 3. The handle 1, hook shank 2, and hook 3 are connected by a bent stainless steel strip. The hook shank 2 is located between the handle 1 and the hook 3, and the two steel strips constituting the handle 1 and the hook shank 2 are parallel to each other. The structure of the hook 3 is as follows: the two steel strips of the hook shank 2 away from the handle 1 are bent at right angles to both sides, then bent at right angles downwards, and then bent at right angles towards the handle 1, and then connected and closed in an arc shape.

[0025] In some examples, reference Figure 3 and Figure 4 The width of the handle 1 is greater than that of the hook shank 2, making the device easy to operate. There is a smooth transition between the handle 1 and the hook shank 2. A first support bar 102 is clamped between the two steel wires of the handle 1, and a stainless steel first sleeve 103 is fixedly sleeved on the outside of the handle 1. A second support bar 201 is clamped between the two steel wires of the hook shank 2, and a stainless steel second sleeve 202 is fixedly sleeved on the outside of the hook shank 2. The sleeve and support bar define the steel wire strips, thus enhancing the structural strength and stability.

[0026] In some examples, reference Figure 1 The outer wall of the first sleeve 103 is provided with anti-slip texture along its width direction, and the anti-slip texture is evenly distributed along the length direction of the first sleeve 103 to reduce possible slippage when operating the device and reduce operational errors.

[0027] In some examples, reference Figure 3 The end of the handle 1 away from the hook 2 is set as a weld point 101 for welding stainless steel strips. Weld point 101 is the final welded connection between the two ends of a section of stainless steel strip used in the production of the device.

[0028] In specific application scenarios, the device is used in the same way as existing products. Hold the handle 1 part and hook the hook 3 to the edge of the cut and gently pull open the cut. However, the difference is that the main body of the device is made of a section of stainless steel strip bent into shape. Then, support strips are inserted into the handle 1 and hook 2 parts and tightened and fixed by the sleeve interference fit. Compared with the steel plate die stamping process, the device has the advantages of simple structure, easy to obtain, easy to operate, and very little processing loss and processing waste.

[0029] The above are merely preferred embodiments of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the invention. These improvements and modifications should also be considered within the scope of protection of the invention. Other parts not detailed in the invention belong to the prior art and will not be elaborated here. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the invention and are not intended to limit it. Although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the invention.
