Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a micro-ring knife used for sebaceous cysts. Background Art

[0002] Sebaceous cysts are cysts formed by the accumulation of sebaceous glands after the sebaceous gland duct is blocked. They are commonly known as "pimples". They are a common benign skin tumor, which is more common in young people in the period of vigorous growth and development. Sebaceous cysts are prone to occur on the skin of the scalp, face and body, showing different depths, different amounts of contents, and different sizes. Sebaceous cysts are prone to infection, causing the cyst to rupture and temporarily subside, but scars will form and are prone to recurrence. Surgery is the best treatment for sebaceous cysts. At present, sebaceous cyst surgery is to make a fusiform skin incision along the skin texture in the center of the cyst to completely remove the cyst. If the cyst wall remains, it is easy to relapse. In order to completely remove the cyst, the surgical incision is usually longer, and if there is a concurrent infection, the skin needs to be cut for drainage, which causes great harm to the patient, especially for sebaceous cysts on the face. The aesthetics of the incision treatment has a greater impact on the appearance, so a micro-ring knife suitable for removing sebaceous cysts is needed. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is clearly and completely described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 The micro-ring knife for sebaceous cysts shown in the figure comprises a ring body 1, a connecting part 2 and a knife body 3, wherein the ring body 1 and the knife body 3 are respectively arranged at the two ends of the connecting part 2, the ring body 1 is a closed circular ring, the outer side of which is fixedly connected to the connecting part 2, one end of the knife body 3 is fixedly connected to the connecting part 2, and the other end is provided with a blade 3-1, the width of the blade 3-1 does not exceed the diameter of the knife body 3, and the width of the blade 3-1 can be less than or equal to the width of the knife body 3 to prevent the wound from expanding during operation; the knife body 3 and the blade 3-1 are integrally formed, and the blade 3-1 is heat-treated to ensure toughness and strength. It is used to make a minimally invasive incision in a sebaceous cyst. The ring body 1 is used to remove the infected necrotic tissue in the cyst, and the necrotic tissue is hooked into the ring to pull out the wound; transition areas 2-1 are provided at both ends of the connecting part 2, and the transition areas 2-1 are chamfers symmetrically arranged along the axis of the connecting part 2. The transition area 2-1 at one end is connected to the ring body 1, and the transition area 2-1 at the other end is connected to the knife body 3. The transition area 2-1 smoothly transitions all connections without sharp convex parts. The annular structure of the ring body 1 and the smooth connection with the transition area 2-1 will not cause secondary damage to the patient, and have clinical safety and convenience; the connection The part 2 includes a rod body 2-2 and a hand-held plate 2-3, the rod body 2-2 is nested in the hand-held plate 2-3 and both ends extend out of the hand-held plate 2-3, and both ends of the rod body 2-2 are fixedly connected to the ring body 1 and the knife body 3 through the transition zone 2-1; the ring body 1, the connecting part 2 and the rod body 2-2 are all made of medical grade stainless steel, such as 316L for scalpels; the hand-held plate 2-3 can be round, oval or irregular fluid shape; the hand-held plate 2-3 is provided with an anti-slip pattern, which can be a convex point, a groove or a texture; the hand-held plate 2-3 can be made of non-metallic material or stainless steel The rod body 2-2 of Example 1 is an integrated structure that passes through the hand-held plate 2-3 and extends from both ends.
