Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an electric preoperative dermatology knife. Background Technology

[0002] A shaving razor is a surgical instrument specifically designed to remove hair from a specific part of the body. It is generally used for pre-operative preparation. Shaving the hair in the surgical area reduces the number of bacteria on the skin surface, lowering the risk of surgical site infection. A clean skin surface allows the doctor to see the surgical incision and operating area more clearly, facilitating precise surgical procedures. Hairless areas are also easier to bandage and care for after surgery, helping to keep the wound clean and dry, thereby promoting wound healing.

[0003] Most existing shaving razors are simple, disposable, manual products with average shaving effect and low efficiency. Traditional electric shaving razors need to be cleaned and disinfected before and after use to avoid bacterial contamination. Due to the complex structure of the razor head, there are often blind spots during disinfection, resulting in incomplete disinfection and cross-infection when used again. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electric preoperative skin preparation razor to solve the problem that most of the skin preparation razors in the prior art mentioned above are disposable manual products with relatively simple structure, and the shaving effect is generally poor and the efficiency is low. In the process of disinfection before and after use of traditional electric skin preparation razors, due to the complex structure of the blade head, there are easy to have blind spots in the disinfection process, resulting in incomplete disinfection and easy to cause cross-infection when used again.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric preoperative dermatology scalpel, comprising a handle, a support plate fixedly connected to the upper end of the handle, a variable speed motor fixedly connected to the bottom of the support plate, a rotating mechanism fixedly connected to the output end of the variable speed motor, an electric push rod fixedly connected to the top of each rotating mechanism, a fixing member fixedly connected to the top of each electric push rod, a sliding rod slidably connected inside the fixing member, a spring fixedly connected to the bottom of the sliding rod, a pressure sensor fixedly connected to the bottom of the spring, a connecting frame symmetrically fixedly connected to the upper end of one side of the handle, a blade head provided at the top of the handle, a groove provided on one side inside the blade head, a fluid reservoir provided inside the groove, and a pressure plate slidably connected inside the groove.

[0006] Preferably, anti-slip pads are symmetrically fixedly connected to one side of the handle, and control buttons are symmetrically arranged on the adjacent side of the handle.

[0007] Preferably, a magnetic strip is fixedly connected to one side of the inside of the handle, a protective plate is magnetically connected to the bottom of the magnetic strip, and a battery is fixedly connected to the other side of the inside of the handle.

[0008] Preferably, the pressure sensor and the fixing component are fixedly connected.

[0009] Preferably, a locking block is fixedly connected to the top of the sliding rod, and an mounting component is engaged with the outside of the locking block. A blade is fixedly connected to the top of each mounting component, and the mounting component and the blade head are slidably connected.

[0010] Preferably, a sealing ring is fixedly connected inside the handle, and the blade is engaged with the connecting frame via a connector.

[0011] Preferably, each pressure plate has a needle fixedly connected to its bottom, and each pressure plate has a flow hole inside.

[0012] Preferably, each of the cutter heads has a blade mesh slidably connected inside, and an elastic pad is fixedly connected to the bottom of the blade mesh.

[0013] Compared with the prior art, this utility model provides an electric preoperative dermatological knife, which has the following beneficial effects:

[0014] 1. This utility model features a mounting component that engages with a locking block. Starting the variable-speed motor drives multiple mounting components to rotate, thereby enabling the blade to rotate at high speed to cut human hair, improving shaving efficiency. The blade head is connected to the connecting frame via a connector, simplifying the connection and facilitating the installation and replacement of the blade head and blades. This allows for one-time replacement of the blade head and blades, avoiding the risk of cross-infection. Furthermore, it eliminates the need for cleaning and disinfecting the shaving head before and after use, simplifying the process and enhancing the convenience of using the shaving razor.

[0015] 2. This utility model adjusts the blade height by using an electric push rod to move the fixing component and sliding rod upwards. During normal skin preparation, the blade is moved to a suitable position, such as reducing the distance between the blade and the blade net. When encountering skin folds or special areas, the blade is pulled downwards to increase the distance between the blade and the blade net, thus avoiding excessive cutting of the skin. It can also flexibly handle hair in complex terrain. During use, a pressure sensor monitors the pressure between the body and the blade. If the pressure is too high, the control mechanism will cut off the circuit, stopping the blade from rotating. When the pressure decreases, it will rotate again, ensuring safety and preventing skin damage due to excessive pressure.

[0016] 3. Before use, the pressure plate is pressed downwards to puncture the liquid reservoir at the bottom of the pressure plate. The soap liquid stored inside the liquid reservoir flows out through the flow hole and is applied to the skin preparation area. The soap liquid acts as a lubricant and cleaner, making it easier for the hair to be removed by the blade. At the same time, it reduces the friction between the blade and the skin, avoids skin damage, and increases the practicality of the skin preparation knife.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 This utility model provides a technical solution: an electric preoperative dermatology scalpel, including a handle 1, a support plate 7 fixedly connected to the upper end of the handle 1, a variable speed motor 8 fixedly connected to the bottom of the support plate 7, a rotating mechanism 9 fixedly connected to the output end of the variable speed motor 8, an electric push rod 10 fixedly connected to the top of each rotating mechanism 9, a fixing member 11 fixedly connected to the top of the electric push rod 10, a sliding rod 12 slidably connected inside the fixing member 11, a spring 13 fixedly connected to the bottom of the sliding rod 12, a pressure sensor 14 fixedly connected to the bottom of the spring 13, a connecting frame 17 symmetrically fixedly connected to the upper end of one side of the handle 1, and a blade head 18 provided at the top of the handle 1. A groove 20 is provided on one side of the part, and a liquid storage bladder 21 is provided inside the groove 20. A pressure plate 22 is slidably connected inside the groove 20. A locking block 15 is fixedly connected to the top of the sliding rod 12. An installation part 25 is engaged with the outside of the locking block 15. A blade 26 is fixedly connected to the top of the installation part 25. The installation part 25 and the blade head 18 are slidably connected. A sealing ring 16 is fixedly connected inside the handle 1. The blade head 18 is engaged with the connecting frame 17 through the connecting part 19. A needle 23 is fixedly connected to the bottom of the pressure plate 22. A flow hole 24 is provided inside the pressure plate 22. A blade net 27 is slidably connected inside the blade head 18. An elastic pad 28 is fixedly connected to the bottom of the blade net 27.

[0029] In actual operation, the first step is to install the blade head 18 by connecting it to the connecting frame 17 via the connector 19. At this time, the blade 26 is engaged with the locking block 15 via the mounting part 25. The connection method is simple and facilitates the installation and replacement of the blade head 18 and the blade 26, enabling the blade head 18 and the blade 26 to be used and replaced one at a time, avoiding the risk of cross-infection of bacteria. At the same time, there is no need to clean and disinfect the skin preparation knife before and after use. The blade 26 is engaged with the locking block 15 via the mounting part 25. This engaging connection method cleverly utilizes the shape matching and mechanical principles between the components, so that the blade 26 can be firmly connected to the locking block 15, simplifying the use process and improving the convenience of using the skin preparation knife.

[0030] After the blade head 18 and blade 26 are installed, the user can start using the device. The user simply needs to press down on the pressure plate 22. During the pressing process, the pressure plate 22 will move smoothly along the predetermined track into the groove 20. It is worth noting that the bottom of the pressure plate 22 is specially equipped with a needle 23. When the pressure plate 22 moves, the needle 23 also moves downward. Due to the sharpness of the needle 23 and its corresponding position to the reservoir 21, when the pressure plate 22 moves to a certain position, the needle 23 will precisely puncture the reservoir 21. The reservoir 21 is pre-stored with soap solution. Once punctured by the needle 23, the soap solution will flow out from the flow hole 24 under the action of pressure difference and its own gravity. The flowing soap solution will be evenly applied to the area that needs to be prepared. The soap solution plays an important role in this process. On the one hand, it can provide good lubrication, reducing the friction between the hair and the skin, making it easier for the hair to be shaved by the blade 26. On the other hand, the soap solution has a cleaning function, which can pre-clean the skin in the preparation area, further ensuring the smooth progress of the preparation work. At the same time, due to the lubrication effect of the soap solution, it can also effectively reduce the friction between the blade 26 and the skin during the hair removal process, greatly reducing the possibility of skin damage and providing users with a safer and more comfortable preparation experience.

[0031] In this utility model, anti-slip pads 2 are symmetrically fixedly connected to one side of the handle 1, and control buttons 3 are symmetrically arranged on the adjacent side of the handle 1. One control button 3 controls the start and stop of the variable speed motor 8 and the adjustment of the speed of the variable speed motor 8, and the other control button 3 controls the opening and closing of the electric push rod 10. The design of the anti-slip pads 2 makes it easy for medical staff to hold the handle 1 stably for skin preparation operations. The two control buttons 3 control the operation process of the variable speed motor 8 and the electric push rod 10 respectively, which is convenient for medical staff to operate and also helps medical staff to distinguish the operation of the two components.

[0032] In this utility model, a magnetic strip 4 is fixedly connected to one side of the inside of the handle 1, and a protective plate 5 is magnetically connected to the bottom of the magnetic strip 4. A storage battery 6 is fixedly connected to the other side of the inside of the handle 1. The protective plate 5 is attached to the magnetic strip 4, which facilitates the installation and removal of the protective plate 5. When in use, the protective plate 5 can protect the storage battery 6. When the storage battery 6 needs to be charged, the protective plate 5 can be removed to expose the charging hole at the bottom of the storage battery 6 for easy charging.

[0033] In this invention, the pressure sensor 14 and the fixing member 11 are fixedly connected. The pressure sensor 14 monitors the squeezing force between the human body and the blade 26. If the squeezing force is too large, the control mechanism will cut off the circuit and stop the blade 26 from rotating. If the force is reduced, it will rotate again to ensure safety and avoid damage to the skin due to excessive force.

[0034] The working principle and usage process of this utility model are as follows: When in use, first connect the blade head 18 to the connecting frame 17 through the connector 19. At this time, the blade 26 is engaged with the locking block 15 through the mounting part 25. The connection method is simple and facilitates the installation and replacement of the blade head 18 and the blade 26, realizing one-time replacement of the blade head 18 and the blade 26, avoiding the risk of cross-infection of bacteria. At the same time, there is no need to clean and disinfect the skin preparation blade head 18 before and after use, simplifying the usage process and improving the convenience of using the skin preparation blade. Then, press down on the pressure plate 22 to move the pressure plate 22 into the groove 20. During the process, the needle 23 at the bottom of the pressure plate 22 punctures the liquid reservoir 21. The soap liquid stored in the liquid reservoir 21 flows out from the flow hole 24 and is applied to the skin preparation area. The soap liquid plays a lubricating and cleaning role, making it easier for the hair to be scraped by the blade 26, while reducing the friction of the blade 26 on the skin and avoiding skin damage.

[0035] Then, based on the skin condition of the preparation area, a control button 3 activates the electric push rod 10 to move the fixing member 11 and sliding rod 12 up and down, thereby adjusting the height of the blade 26. For example, during normal skin preparation, the blade 26 is moved to a suitable position, such as reducing the distance between the blade 26 and the blade net 27. When encountering skin folds or special areas, the blade 26 is pulled down to increase the distance between the blade 26 and the blade net 27 to avoid over-cutting the skin. It can also flexibly handle hair in complex terrain. Then, another control button 3 controls the variable speed motor 8 to start. The variable speed motor 8 is equipped with a high speed and a low speed. The low speed is suitable for areas with skin folds or special areas, while the high speed is used to smooth areas with dense hair. This allows for flexible adjustment of the cutting speed according to different skin preparation needs, improving skin preparation efficiency and ensuring patient safety. During use, the pressure sensor 14 monitors the squeezing force between the human body and the blade 26. If the squeezing force is too large, the control mechanism will cut off the circuit, causing the blade 26 to stop rotating.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
