Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a novel ophthalmic deep retractor device. Background Technology

[0002] In ophthalmic surgery, especially lateral retinal surgery, orbital foreign body removal, or tumor extraction, the exposure of the surgical area and the blocking traction of adjacent tissues are crucial. Existing deep ophthalmic retractor devices are mostly solid, plate-like structures with a narrowed, outwardly curved trapezoidal shape. The blocking area provided by the hook is relatively small, failing to effectively block surrounding tissues. The solid hook plate is often located precisely in the center of the surgical field, obstructing the operation. The outwardly curved structure conflicts with the spherical ocular surface, further narrowing the longitudinal space of the deep surgical field. The retractor structure lacks length markings, often requiring additional ruler measurements during surgery, increasing the complexity of the procedure due to instrument interference. In cases where the retinal tear is located below the extraocular muscles, the solid retractor plate is obscured by the rectus muscles, preventing simultaneous exposure of the surgical field, leading to prolonged surgery time, increased complexity, and an inability to adequately meet the needs of deep ophthalmic surgery, thus affecting surgical outcomes. Therefore, developing a retractor device suitable for use in deep surgeries is of paramount importance. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a novel ophthalmic deep retractor device to solve the issues raised in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel ophthalmic deep retractor device, wherein the retractor body is an inverted trapezoid with an enlarged end, a U-shaped hollow groove is formed through the middle of the retractor body, and two toothed edges are formed on both sides of the U-shaped hollow groove of the retractor body. The outer surface of the two toothed edges of the retractor body is provided with scale lines, and the inner edge of the retractor body located in the U-shaped hollow groove is provided with scale protrusions corresponding to the scale lines. The two retractor bodies are connected by the same handle.

[0005] Furthermore, the hook bodies are located on both sides of the handle, forming a Z-shape with the handle.

[0006] Furthermore, the hook body is divided into three parts: an arc-shaped part, a etched part, and a hook tip part. The end connected to the handle is the arc-shaped part. The etched part is an arc-shaped concave part, the curvature of which matches the curvature of the eyeball. The end of the hook tip part is a blunt round protrusion.

[0007] Furthermore, the handle has a length of 50-80mm and a thickness of 1mm.

[0008] Furthermore, the height of the arc-shaped portion of the hook body is 10mm, the total length of the scale line portion and the hook tip portion is 30mm, and the thickness of the hook body is 1mm.

[0009] Furthermore, the total length of the hook body is 40mm, and the width of the arc-shaped part connected to the handle is 10mm, the width of the two toothed edges is 5mm, and the distance between the two toothed edges is 5mm.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model provides a larger blocking area through the inverted trapezoidal design, the double-tooth hollow design reduces obstruction and has strong adaptability, the hook tip is designed as a blunt round protrusion to avoid damage to the eye tissue, and has high safety.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] This utility model provides a novel deep ophthalmic retractor device, such as... Figure 1-2 As shown, the device includes a retractor body 1, which is an inverted trapezoid with an enlarged end. A U-shaped hollow groove 101 is formed through the middle of the retractor body 1, and two toothed edges 102 are formed on both sides of the U-shaped hollow groove 101. The V-shaped groove 101 leaves the main area in the middle of the retractor body 1 open, exposing more of the core surgical field and reducing the impact on surgical operations. The open toothed edges 102 in the middle of the retractor body 1 can straddle the rectus abdominis muscle, facilitating a single exposure of the surgical field where the retinal tear is located under the extraocular muscle. The two toothed edges 102 of the retractor body 1... The outer surface of the toothed edge 102 is provided with scale lines 103. The inner edge of the hook body 1 located in the U-shaped hollow groove 101 is provided with scale protrusions 104 corresponding to the scale lines 103. Clear scale markings are provided on the hook body 1 to facilitate real-time measurement of the depth and position of the hook during surgery, reduce the need for other measuring tools, and improve surgical efficiency. The two hook bodies 1 are connected by the same handle 2. The hook body 1 is made of medical-grade stainless steel or titanium alloy and has a certain degree of curvature and elasticity to adapt to the curvature of the eyeball.

[0019] like Figure 1-2 As shown, the retractor body 1 is located on both sides of the handle 2, forming a Z-shape with the handle 2. This ergonomic design facilitates gripping and operation by the surgeon. The retractor body 1 is divided into three parts: an arc-shaped part 3, a scribed part 4, and a hook tip 5. The end connected to the handle 2 is the arc-shaped part 3. The scribed part 4 is concave, its curvature matching the curvature of the eyeball. The end of the hook tip 5 is a blunt, rounded protrusion 6, which allows it to penetrate deep into the eyeball tissue without damaging the surface or internal tissues. The outer protrusion... This facilitates further opening of the sclera and peribulbar fascia at the end, exposing more surgical space; the handle 2 is 50-80mm long and 1mm thick; the arc-shaped part 3 of the hook body 1 is 10mm high, the total length of the scale line 103 and the hook tip 5 is 30mm, and the thickness of the hook body 1 is 1mm; the total length of the hook body 1 is 40mm, and the width of the end where the arc-shaped part 3 connects to the handle 2 is 10mm, the width of the two toothed edges 102 is 5mm, and the distance between the two toothed edges 102 is 5mm.

[0020] Although the present 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 of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
