Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a nail plate separator for treating paronychia. Background Technology

[0002] The nail groove refers to the junction where the nail root connects to the skin. Paronychia is an inflammatory disease caused by bacterial infection of the soft tissue in the depression around the nail plate or toenail. In the fingers, paronychia is often caused by injuries such as puncture wounds, tearing off hangnails, or cutting nails too short. In the toes, it is often caused by ingrown toenails or shoes that are too tight, which compress the side edge of the toenail and cause it to grow into the soft tissue of the nail groove, rubbing against the nail and nail fold, causing swelling of the soft tissue and aggravating the ingrown toenail. The symptoms of paronychia include acute or chronic suppurative, tender, and painful swelling of the periungual tissue. If not treated in time, it can become chronic paronychia or chronic osteomyelitis of the finger bones.

[0003] Traditional instruments for treating paronychia mostly consist of nail clippers or nail razors, which have the following drawbacks: Insufficient operational precision: Conventional scalpels or nail curettes cannot penetrate the narrow nail groove area, easily causing accidental injury to the healthy nail bed or surrounding skin, resulting in a high postoperative recurrence rate; Low debridement efficiency: When necrotic tissue is tightly adhered to the nail plate, ordinary curettes cannot completely remove necrotic tissue, requiring repeated operations and prolonging wound exposure time; Poor instrument compatibility: Existing tools have limited functions, requiring frequent instrument changes during surgery, increasing patient pain and infection risks; Ergonomic defects: Straight-handled instruments have limited operating angles under the arc-shaped anatomical structure of the nail groove, severely obstructing the surgical field and affecting the surgeon's operational fluency. Therefore, a nail plate separator for treating paronychia is designed to overcome the above-mentioned technical defects. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a nail plate separator for treating paronychia to solve the above-mentioned technical problems.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a nail plate separator for treating paronychia, including a handle, with blades connected to both ends of the handle via connecting rods. The blades are integrally formed with the connecting rods, and the blades include a straight part and a curved part, with a serrated part in the middle of one end of the curved part.

[0008] Preferably, the handle has a hexagonal cross-section with rounded corners, and the outer side of the handle is uniformly provided with anti-slip texture.

[0009] Preferably, threaded holes are provided at the center of both ends of the handle.

[0010] Furthermore, the end of the connecting rod away from the cutter head is integrally formed with a threaded post, and the end of the threaded post away from the connecting rod is threaded into a threaded hole.

[0011] Furthermore, a support ring is fitted on the outer side of the connecting rod near the cutter head, and the support ring is made of plastic.

[0012] Furthermore, the straight section and the curved section are integrated into one structure, with an angle of 10-15 degrees between the curved section and the straight section.

[0013] Furthermore, both the upper and lower ends of the straight section and the upper and lower ends of the curved section are provided with smooth cutting edges, and the tooth pitch of the serrated section is 0.5-1.2mm.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes connecting rods screwed to both ends of the handle to easily replace damaged blades. The blade consists of a straight section, a curved section, and a serrated section. The curved and straight sections have a biomimetic angle, allowing the curved section to conform to the natural curvature of the nail groove and nail bed, enabling it to penetrate deep into the nail groove. Combined with the serrated section, it precisely separates ingrown nails and necrotic tissue, increasing the preservation rate of healthy tissue, reducing intraoperative bleeding, and shortening the postoperative recovery period. Furthermore, its multi-functional integration reduces the number of instrument changes, decreases the time required for a single surgery, and lowers the risk of complications. The integrated operation reduces wound exposure, resulting in a lower postoperative infection rate. Attached Figure Description

[0024] Example 1

[0025] This specific embodiment is a nail plate separator for treating paronychia, and its structural schematic diagram is shown below. Figures 1-6 As shown, it includes a handle 1, and both ends of the handle 1 are connected to a blade 3 via a connecting rod 2. The blade 3 is integrally formed with the connecting rod 2. The blade 3 includes a straight part 5 and a curved part 6. A serrated part 7 is provided in the middle of one end of the curved part 6.

[0026] Specifically, this separator is based on a dental periosteal separator and adapted for cross-domain functions. The curved part 6 adopts a human biomimetic engineering design, so that the curved part 6 conforms to the natural curvature of the nail groove and nail bed, reducing the compression damage to the healthy tissue around the nail. The serrated part 7 can realize bidirectional cutting (pushing and pulling action) and necrotic tissue scraping simultaneously on one side of the curved part 6. The gap between the serrations can hook fibrotic necrotic tissue to prevent slippage.

[0027] In addition, the grip 1 has a hexagonal cross-section with rounded corners, and the outer side of the grip 1 is uniformly provided with anti-slip texture; the addition of anti-slip texture to the grip 1 can increase the friction between the hand and the grip 1, and improve the stability of operation.

[0028] In addition, the straight part 5 and the curved part 6 are integrated into one structure, and the angle between the curved part 6 and the straight part 5 is 10-15 degrees. The straight part 5, together with the curved part 6, allows the blade 3 to penetrate deep into the nail groove. Combined with the serrated part 7, it can accurately separate the embedded nail from the necrotic tissue, thus improving the preservation rate of healthy tissue.

[0029] In addition, the upper and lower ends of the straight part 5 and the upper and lower ends of the curved part 6 are provided with smooth cutting edges, and the tooth pitch of the serrated part 7 is 0.5-1.2mm; the smooth cutting edge of the middle section of the original periosteum stripper is used for plate separation, and combined with the necrotic tissue removal function of the serrated section, a single instrument can complete the entire process of "separation-cutting-debridement".

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that threaded holes are provided at the middle of both ends of the handle 1; a threaded post 8 is integrally formed at the end of the connecting rod 2 away from the blade 3, and the end of the threaded post 8 away from the connecting rod 2 is threaded into the threaded hole; a support ring 4 is sleeved on the side of the connecting rod 2 near the blade 3, and the support ring 4 is made of plastic; the blade 3 can be threadedly connected to the handle 1 through the connecting rod 2. The service life of the handle 1 is much longer than that of the blade 3. The blade 3 is easily damaged by collisions and falls. In this case, it is only necessary to separate the damaged blade 3 from the handle 1 and replace it with a new blade 3, which can save some costs; at the same time, the support ring 4 can support the fingers holding the handle 1 and the connecting rod 2 when treating paronychia through this separator, thereby facilitating the application of force by the fingers and greatly improving the flexibility and accuracy of operation.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
