Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a scraper for treating underarm odor. Background Technology

[0002] The axillary odor curette is a plastic surgical instrument specifically used for axillary odor surgery. It is mainly used to scrape away the apocrine gland tissue and skin cysts under the armpit to achieve the purpose of treatment. During the operation, the curette is inserted through a small incision of about 3mm under the armpit to scrape away the subcutaneous sweat gland tissue and close the sweat gland opening. The commonly used types are: round curettes (such as Curtis curettes), oval curettes, and scrapers, etc. Clinical feedback revealed several drawbacks to the use of traditional round scrapers, as their shape does not match the square folds of the armpit. Firstly, there is a high rate of residue in the armpit corner area: traditional scrapers tend to leave behind tissue in the armpit folds (especially apocrine sweat glands) when scraping sweat glands. Secondly, safety is poor: the sharp outer edge of the scraper is designed with a curved blade, which can easily cut through the skin. Finally, the operation is relatively cumbersome: the scraping surface is small and the scraper needs to be repeatedly pulled out of the body, and then the tissue is extracted and circulated using a suction device. Utility Model Content

[0003] Therefore, in order to solve the above problems and shortcomings, this utility model provides a scraper for treating underarm odor, including a blade and a handle. One end of the blade is embedded in the handle, and the other end of the blade has a scraper. Symmetrical outer and inner shaving surfaces are formed along the end face of the blade and the blade end is flattened. The scraper is formed by bending the flat blade end by 90°, and a right-angled surface is formed at the bend. The edge of the scraper has rake teeth, and side surfaces are formed by bending and extending along both sides of the right-angled surface to the outer and inner shaving surfaces. A suction device is provided on the inner shaving surface extending into the blade. The suction device consists of an inner tube and suction ports and interfaces connected to both ends of the inner tube. The entire inner tube is located inside the blade, and the interface extends to the tail of the handle.

[0004] Furthermore, the inner cutting surface is recessed inward on the side near the suction port to form a concave spoon surface, and the suction port is closely adjacent to the inner side of the concave spoon surface and integrally formed with the knife handle.

[0005] Furthermore, the rake teeth consist of several cutting teeth and two symmetrically distributed side teeth, with a toothed opening formed between any of the cutting teeth.

[0006] Furthermore, the concave spoon surface has a teardrop shape when viewed from above, and the depth of the end closer to the suction nozzle is greater than the depth of the end farther from the suction nozzle.

[0007] Furthermore, an outer tube surface is provided surrounding the suction port and extending towards the tool holder, and the outer tube surface and the tool holder are smoothly integrally formed.

[0008] Furthermore, the inner cutting width of the cutting tooth is smaller than the outer cutting width, and the edge of the outer cutting tooth has a rounded corner.

[0009] Furthermore, both the right-angled surfaces and the side surfaces have rounded corners.

[0010] The beneficial effects of this utility model can be specifically analyzed as follows: Advantage 1: This application adopts a curette combined with a suction device design to scrape off subcutaneous sweat gland tissue. During the scraping process, the scraped tissue is simultaneously suctioned by the suction device. This ensures thorough scraping while eliminating the need for the surgeon to repeatedly perform scraping-suction operations, thus improving scraping efficiency and reducing surgical time.

[0011] Advantage 2: In this application, the right-angled surface on the back of the scraper and the outer surface of the rake teeth are designed to be smooth, ensuring that the cutting force of the rake teeth only acts on the tissue inside the cavity, and the outer edge R-angle automatically slips off when in contact with the skin, avoiding scratching and reducing the probability of skin damage.

[0012] Advantage 3: The inner width of the blade in this application is smaller than the outer width, and the edge of the outer blade is rounded. The inner side of the two edge teeth has a cutting edge, while the outer side has a smooth design. Clinical verification has effectively increased the area removed in a single scraping, improved scraping efficiency, significantly reduced the rate of residual sweat glands, and decreased the postoperative recurrence rate.

[0014] The present invention will now be described in detail with reference to the accompanying drawings, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Throughout the invention, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. It should be understood that ordinal numbers and directional descriptions, such as "first," "second," "third," "upper," "lower," "left," and "right," are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly and not as limiting the scope of this utility model.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the attached drawings. Figure 1-5 As shown, this application provides a scraper for treating underarm odor, including a blade 1 and a handle 2. One end of the blade 1 is embedded in the handle 2. The blade 1 is made of hollow 420 stainless steel, TC4 titanium alloy, etc. The handle 2 and the suction device 4 are designed with appropriate special materials to meet medical sterility standards. The other end of the blade 1 has a scraper 3. Symmetrical external cutting surfaces 31a and internal cutting surfaces 31b are respectively opened along the end face of the blade 1 towards the blade 1. The two cutting surfaces make the end of the blade 1 flat. The scraper 3 is flat. The blade handle 1 is formed by bending the end at 90°, creating a right-angled surface 33. The scraper 3 has serrated edges 34, and side surfaces 32 extend outwards towards the outer and inner cutting surfaces 31a and 31b respectively, along the right-angled surface 33. An aspirator 4 extends inwards from the inner cutting surface 31b into the blade handle 1. The aspirator 4 consists of an inner tube 41 and suction ports 42 and interfaces 43 connected to both ends of the inner tube 41. The inner tube 41 is entirely within the blade handle 1, and the interfaces 43 extend to the tail of the handle 2. Based on this structure, the scraper 3, located at the end of the blade handle 1, is inserted through a small incision to scrape away subcutaneous sweat gland tissue. During the scraping process, the aspirator 4 simultaneously suctions the scraped tissue, ensuring thorough scraping without requiring repeated scraping-suction operations by the surgeon, thus improving scraping efficiency and reducing surgical time.

[0016] Please see Figure 2-3 As shown, the inner facet 31b is recessed inward on the side near the suction port 42 to form a concave spoon surface 421. The suction port 42 is close to the inner side of the concave spoon surface 421 and is integrally formed with the knife bar 1. An outer tube surface 423 is provided surrounding the suction port 42 and extending towards the knife bar 1. The outer tube surface 423 and the knife bar 1 are integrally formed with a smooth surface. The right angle surface 33 and the side surface 32 are both rounded.

[0017] Based on the above embodiments, the outer cutting surface 31a and the inner cutting surface 31b make the head of the blade 1 flat, which facilitates the construction of the scraper 3. The right-angled surface 33 and the outer surface of the rake teeth 34 on the back of the scraper 3 are both designed to be smooth, ensuring that the cutting force of the rake teeth 34 only acts on the tissue inside the cavity. The outer edge R angle automatically slips off when it contacts the skin, avoiding scratching and reducing the probability of skin damage.

[0018] Please refer to the following: Figure 4-5 As shown, the rake tooth 34 is composed of several blade teeth 343 and two symmetrically distributed side teeth 342. A toothed edge 341 is formed between any blade teeth 343. The blade teeth 343 adopt an isosceles triangular design, and their inner blade width is smaller than their outer blade width. The edge of the outer blade teeth 343 has a rounded corner. The inner side of the two side teeth 342 has a cutting edge, while the outer side has a smooth design, so that the rake tooth 34 forms a right-angled structure with a square head. In this way, it can completely fit the rectangular fold area of ​​the armpit, and can scrape away sweat glands and tissues to the greatest extent, eliminating the "crescent-shaped dead angle" of traditional curved scrapers. More importantly, the inner blade width used in this application is smaller than the outer blade width, which avoids the sharp outer edge of the scraper. This avoids accidental damage to the subcutaneous vascular network and hematoma, and also prevents the need for excessive pressure from blunt edge instruments, which increases the risk of skin necrosis.

[0019] like Figure 2-3 As shown, the concave spoon surface 421 has a teardrop shape when viewed from above, and the depth of the end closer to the suction nozzle 422 is greater than the depth of the end farther away from the suction nozzle 422. The concave spoon surface 421 is located within the inner enclosure of the inner shaving surface 31b, while the suction nozzle 422 is located at the deepest part of the concave spoon surface 421. The suction nozzle 422 can maintain most of its protrusion while maintaining a smooth connection with the inner shaving surface 31b, avoiding the skin being scratched by the protruding suction nozzle 422 during scraping. In other words, the inner enclosure design of the suction nozzle 422 can work with the square rake teeth 34 to increase the area scraped in a single operation while achieving rapid suction, thereby avoiding repeated scraping-suction operations. Only a final suction check can be performed at the last stage using a suction device.

[0020] It should be noted that the interface 43 at the tail of the suction device 4 is used to maintain a detachable connection with the external negative pressure device. The negative pressure device is equipped with a sweat gland tissue collection box. After skin cysts or sweat glands and other tissues are scraped off, they are sucked into the negative pressure collector through the suction nozzle 422, passing through the inner tube 41 and the interface 43.

[0021] In summary, this utility model of axillary odor scraping tool adopts a design that combines a scraping tool 3 with a suction device 4, which increases the area to be scraped in a single operation to improve scraping efficiency, reduce operation time, improve clinical efficacy, significantly reduce the rate of residual sweat glands, decrease the postoperative recurrence rate, and reduce the probability of skin damage.

[0022] The above are merely embodiments of this utility model. Common knowledge such as specific structures and characteristics in the solutions are not described in detail here. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and they will not affect the implementation effect of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
