[0026] One preferred embodiment of this application, such as Figures 1 to 7 As shown, a disposable medical shaving razor includes a razor body 1; a hair-adhesive component 2 is provided on at least one side of the razor body 1, and the hair-adhesive component 2 and the razor body 1 are connected by a connecting structure 3; by providing the hair-adhesive component 2 on the side of the razor body 1, it is convenient to collect and clean the shaved hair, thereby enabling the razor body 1 to shave more effectively; when shaving hair, the razor body 1 with the hair-adhesive component 2 is in contact with the skin, and the hair-adhesive component 2 can adhere to the hair. When the razor body 1 moves to shave, the hair-adhesive component 2 rotates and stretches and fixes the adhered hair, so that the razor body 1 can shave the fixed hair when moving, thereby improving the shaving effect of the razor body 1. Subsequently, the cut hair can adhere to the hair-adhesive component 2 as it rotates, making it convenient to shave and collect the hair, facilitating better hair removal, simple and convenient operation, strong practicality, and high safety.

[0027] In this embodiment, as Figure 1 and Figure 2As shown, it should be understood that the shaving knife body 1 includes a handle frame 11, a blade 12, and a fixing block 13; one side of the handle frame 11 is for personnel to hold, and the blade 12 is installed on the other side of the handle frame 11. The fixing block 13 is located on the side of the blade 12 and is installed on the handle frame 11 to fix the blade 12, so that the blade 12 can be stably installed on the handle frame 11 for shaving.

[0028] It is understandable that, such as Figures 1 to 3 As shown, the lint-adhesive assembly 2 cooperates with the blade 12. Therefore, when the shaving razor body 1 can shave on both sides, two sets of lint-adhesive assemblies 2 can be provided. The two sets of lint-adhesive assemblies 2 are installed on both sides of the shaving razor body 1 through the connecting structure 3. When the shaving razor body 1 is single-sided, one set of lint-adhesive assemblies 2 can be provided. One set of lint-adhesive assemblies 2 is installed on the side of the shaving razor body 1 used for shaving through the connecting structure 3, thereby making the device more adaptable and convenient.

[0029] In this embodiment, as Figure 1 As shown, in order for personnel to better hold the shaving knife body 1 for shaving, anti-slip texture is provided on the side of the handle frame 11, which can make the personnel hold the handle frame 11 more stably, thereby improving the safety during shaving.

[0030] In this embodiment, as Figure 1 , Figures 3 to 6 As shown, the lint-removing assembly 2 includes a U-shaped plate 21 and a lint roller 22. The U-shaped plate 21 is mounted on the side of the handle holder 11 via a connecting structure 3, and the lint roller 22 is detachably and rotatably mounted on the side of the U-shaped plate 21. The lint roller 22 facilitates the adhesion and removal of hair, resulting in better shaving results and making shaving easier for the operator. When shaving, the lint roller 22 can be first installed on both sides of the U-shaped plate 21. After installation, the U-shaped plate 21 can be mounted on the handle holder 11 via the connecting structure 3. Then, during shaving, the operator holds the handle holder 11 and places the shaving blade body 1, along with the lint roller 22, against the skin. The lint roller 22 adheres to the hair, and the blade 12 can shave the hair as the shaving razor body 1 moves. At this time, the lint roller 22 rotates on the skin surface to stretch and fix the adhered hair, so that the blade 12 can shave the fixed hair when it moves, thereby improving the shaving effect of the shaving razor body 1. Subsequently, the cut hair can adhere to the lint roller 22 as it rotates. At the same time, the lint roller 22 can adhere to the hair as it moves downward, so that it can be cut and collected by the blade 12, which facilitates better hair removal. The operation is simple and convenient, making it easy to remove and collect hair. It is highly practical and safe.

[0031] In this embodiment, as Figure 3, Figure 5 and Figure 6 As shown, the lint roller 22 is provided with an anti-adhesive paper on the outside, which helps to protect the adhesiveness of the lint roller 22, so that it can better adhere to hair.

[0032] It should be known that, as Figure 3 , Figure 5 and Figure 6 As shown, the lint roller 22 has arc-shaped protrusions on both sides, and the U-shaped plate 21 has mounting grooves on both sides, so the lint roller 22 can be detachably installed on the U-shaped plate 21. Since the lint roller 22 is detachably installed on the U-shaped plate 21, when the lint roller 22 has adhered to a sufficient amount of hair, the lint roller 22 can be removed and replaced with a new lint roller 22, thereby enabling the device to better adhere, collect and clean, and further improve the practicality and convenience of the device.

[0033] In this embodiment, as Figures 3 to 5 As shown, the connecting structure 3 includes round protrusions 31 installed on both sides of the U-shaped plate 21 and round grooves 32 formed on both sides of the handle holder 11; the round protrusions 31 and the round grooves 32 cooperate with each other; thus, when shaving hair, the lint roller 22 can be installed on both sides of the U-shaped plate 21 first. After installation, the round protrusions 31 at both ends of the U-shaped plate 21 can be aligned with the round grooves 32 on both sides of the handle holder 11, so that the U-shaped plate 21 can be installed on the handle holder 11. Then, when shaving, the person takes the handle holder 11 and places the shaving knife body 1 with the lint roller 22 against the skin. The lint roller 22 can adhere to the hair. When the shaving knife body 1 moves, the hair can be scraped off by the blade 12. The lint roller 22 rotates on the skin surface to stretch and fix the adhered hair, allowing the blade 12 to shave off the fixed hair as it moves, thus improving the shaving effect of the shaving knife body 1. The cut hair then adheres to the lint roller 22 as it rotates, and the lint roller 22 can also adhere to the hair as it moves downwards, allowing it to be cut and collected by the blade 12 for better hair removal. The operation is simple and convenient, facilitating hair removal and collection. When the lint roller 22 has adhered to a sufficient amount of hair, it can be removed and replaced with a new lint roller 22, allowing the device to better adhere, collect, and clean, further improving the device's practicality and convenience.

[0034] In this embodiment, as Figure 1 , Figure 6 and Figure 7As shown, it should be understood that in order to better protect the skin of the personnel during the preparation and shaving of hair, and to prevent the blade 12 of the preparation knife body 1 from scratching the skin, a removable protective toothed sleeve 4 is provided on the side of the U-shaped plate 21 by means of a buckle. The protective toothed sleeve 4 is provided to protect the blade 12, thereby preventing the blade 12 from scratching the skin of the personnel, protecting the integrity of the skin, reducing the infection rate of the surgical site, making the operation simple and convenient, and further improving the safety of the device.

[0035] It is understandable that, such as Figure 1 , Figure 6 and Figure 7 As shown, the length of the protective sleeve 4's teeth 42 can be 4mm, 5mm, 6mm, 7mm, 8mm, etc., so as to adapt to the needs of different personnel.

[0036] It should be understood that when the shaving razor body 1 is used for shaving, the blade 12 is relatively close to the hair and is quite sharp. Therefore, the blade 12 can easily scratch the skin during pre-operative shaving, leading to damage to the surgical site and potentially causing infection. To better protect the integrity of the skin and prevent scratches during shaving, a removable protective sleeve 4 is attached to the side of the U-shaped plate 21 via a buckle. The length of the guard teeth 42 of the protective sleeve 4 can be selected to accommodate different shaving needs. The protective sleeve 4 ensures that the blade 12 is at a certain distance from the hair root, so that the hair root is at the same length as the guard teeth 42 of the protective sleeve 4 during shaving, thus preventing the blade 12 from scratching the skin and ensuring the integrity of the surgical site, thereby avoiding surgical site infection caused by skin scratches.

[0037] In this embodiment, as Figures 3 to 7As shown, the protective sleeve 4 includes an mounting strip 41 and multiple guard teeth 42. The mounting strip 41 is installed on the side of the U-shaped plate 21 via a snap-fit ​​mechanism. The multiple guard teeth 42 are equidistantly arranged on the side of the mounting strip 41 and cooperate with the blade 12. When shaving, the protective sleeve 4 can be installed on the U-shaped plate 21 via a snap-fit ​​mechanism to protect the user's skin and prevent the blade 12 of the shaving knife body 1 from scratching the skin. Then, the lint roller 22 is installed on both sides of the U-shaped plate 21. After installation, the round protrusions 31 at both ends of the U-shaped plate 21 can be aligned with the round grooves 32 on both sides of the handle holder 11, so that the U-shaped plate 21 can be installed on the handle holder 11. Then, when shaving, the user takes the handle holder 11 and places the shaving knife body 1 with the lint roller 22 against the skin. The lint roller 22 can then be used to remove hair. The lint roller 22 adheres to the skin and, as the shaving blade 1 moves, scrapes the hair off with the blade 12. Simultaneously, the rotating lint roller 22 stretches and fixes the adhered hair, allowing the blade 12 to shave off the fixed hair, thus improving the shaving effect of the shaving blade 1. The cut hair then adheres to the lint roller 22 as it rotates, and the lint roller 22 also adheres to the hair as it moves downwards, allowing for cutting and collection by the blade 12. This facilitates better hair removal, is simple and convenient to operate, and makes hair removal and collection easy. When the lint roller 22 has adhered to a sufficient amount of hair, it can be removed and replaced with a new one, allowing for better adhesion, collection, and cleaning, further enhancing the device's practicality and convenience.
