Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic surgical instruments, in particular to a disposable ophthalmic scalpel. Background Art

[0002] An ophthalmic scalpel is an instrument specifically used in ophthalmic surgery, used for cutting and excision during eye surgery. Its fine, sharp blade ensures high-precision cutting, ensuring a safe and successful operation. The key features of an ophthalmic scalpel are as follows: First, its exceptionally sharp blade easily cuts ocular tissue, minimizing surgical trauma. Second, its small size allows for delicate surgical procedures while protecting the integrity of surrounding tissue. Furthermore, an ophthalmic scalpel features excellent blade retention, ensuring blade stability during surgery and minimizing surgical risks. An ophthalmic scalpel typically consists of a handle and a blade. The handle is typically made of stainless steel, offering an excellent grip and excellent handling. The blade is crafted from high-quality medical stainless steel and meticulously processed and polished to ensure its sharpness and durability.

[0003] Ophthalmic scalpel products are used for ophthalmic surgery. The product structure usually consists of two parts: a blade and a handle. There are many types of ophthalmic scalpel products. Commonly used products include side cutters, implant knives, puncture knives, tunnel knives, etc.

[0004] For example, application number 201810967873.8 discloses a scalpel equipped with a safety blade protection cover, comprising a scalpel body and a blade protection cover. The rear end of the scalpel body is configured as a handle, and the front end of the scalpel body is configured as a blade. The end surfaces of the blade head are provided with strip-shaped marking ribs, and the bottom of the blade head is provided with an arc-shaped blade surface. The blade protection cover is correspondingly sleeved onto the scalpel body. One open end of the blade protection cover is a flush end surface, and the other open end of the blade protection cover is a curved surface. The end surfaces of the blade protection cover are provided with openings extending through them, and the end surface of the blade protection cover at the rear end of the opening is engraved with scale marks. Through the above-mentioned method, the present invention is a safe scalpel for use by doctors and assistant doctors. The blade protection cover is sleeved on the scalpel body to protect medical staff from scratches. When in use, the blade protection cover is pushed toward the handle to expose the blade. The push-pull length is determined by the expected cutting depth.

[0005] However, existing disposable ophthalmic scalpels have limited optional additional functions. Although attempts are made to reduce manufacturing costs, auxiliary applications and prompt functions such as anti-counterfeiting identification and safe use during the application process are obviously insufficient. For example, disposable products are used repeatedly, or due to the lack of a blade protection structure, there is a risk of accidental scratches when taking the knife out of the packaging box and passing it. At the same time, the differentiated structural features that support products of different brands are not obvious enough. Utility Model Content

DETAILED DESCRIPTION

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Example 1

[0026] Reference Figure 1-2 A disposable ophthalmic scalpel includes a knife rod 2 and a knife head 1. The knife rod 2 is fixedly connected to a knife seat 3 on the side close to the knife head 1. The knife seat 3 is fixedly connected to the knife head 1 at one end away from the knife rod 2. An external mounting knife sleeve 5 is provided on the knife head 1. One end of the external mounting knife sleeve 5 is closed and the other end is open. Product marks 4 are provided on the outer walls of the knife seat 3 and the knife rod 2.

[0027] In the present utility model, the open end of the externally mounted knife sheath 5 is sleeved on the knife seat 3, and the open end of the externally mounted knife sheath 5 cooperates with the knife seat 3. A blade cover 6 is sleeved on the knife head 1, and the blade cover 6 cooperates with the knife head 1. The externally mounted knife sheath 5 and the knife seat 3 are connected through a tear opening 7.

[0028] In the present invention, when in use, the front end of the externally mounted knife sheath 5 is closed, and the rear end is sleeved and fixed on the knife holder 3. Before using the surgical knife, check that the appearance is normal and complete. Then, apply sufficient force to destroy the tear opening 7 and pull open the rear end of the externally mounted knife sheath 5 fixed on the surface of the knife holder 3. Pull the externally mounted knife sheath 5 out to the front side to expose the knife head 1, the knife holder 3 or the complete product mark 4.

[0029] Example 2

[0030] Reference Figure 3-4 The difference between Example 2 and Example 1 is that, in this embodiment, a telescopic ring thread 51 is provided on the externally mounted knife sleeve 5, a heat shrink ring mouth 52 is provided on the end of the externally mounted knife sleeve 5 close to the knife seat 3, two symmetrically arranged front blocking rings 31 are provided on the knife seat 3, a front end ring groove 53 is provided on the side wall of the end of the externally mounted knife sleeve 5 away from the knife rod 2, an easy-to-tear end cover 54 is provided on the end of the externally mounted knife sleeve 5 close to the cutter head 1, two flat grooves 8 are provided on the outer wall of the knife rod 2, and the two flat grooves 8 are symmetrically arranged, a cutting edge direction mark 9 is provided on the product mark 4 located on the knife seat 3, an embedded wire 10 is provided in the knife rod 2, and the end of the embedded wire 10 is fixedly connected to the side wall of the open end of the external knife sleeve 5.

[0031] In this embodiment, the externally mounted knife sleeve 5 is configured as a telescopic tube structure having a telescopic ring groove 51, which can facilitate the externally mounted knife sleeve 5 to be pulled out from the front end, or to be pulled back backward and fixed so as to expose the cutter head 1. In the latter case, for the externally mounted knife sleeve 5 structure with a closed front end, it is necessary to remove the tearable end cover 54 structure at the front end of the externally mounted knife sleeve 5 in advance.

[0032] In the case of pursuing higher quality, an embedded wire 10 is set at the same time. The embedded wire 10 is connected to the outer mounting knife cover 5 on the front side. When the outer mounting knife cover 5 is removed, the embedded wire 10 is pulled out together to cause obvious changes on the surface of the knife seat 3 or the knife rod 2, showing the use mark, so as to achieve the effect of preventing reuse. The outer mounting knife cover 5 is suitable for side cutting knives, tunnel knives, spear-type puncture knives and other ophthalmic surgical knives, such as Figure 1 、 4 The cutter head 1 in the figure is shown as a tunnel cutter. Figure 2 The blade head 1 in the figure is shown as a side incision knife. Figure 3 The blade head 1 in FIG. 1 is shown as a puncture blade.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
