Definitions

• the present disclosure relates to medical devices, more particularly, to a skin removing device.
• a water-proof treatment and a sealing treatment for the switch and the motor base are required.
• the life of the sealing structure is limited. Thus, some elements of the skin removing device may be aged or worn after long-term use and several times of disinfection, which may influence the normal operation of the skin removing device. In order to maintain the skin removing device in a good operation condition, the sealing structure needs to be replaced in time.
• the skin removing device comprises: a cutting assembly adapted to cut skin; an adjusting assembly adapted to adjust a cutting area of the cutting assembly and configured to fixedly couple with the cutting assembly; a handle-switch assembly comprising a handle assembly configured to fixedly couple with a first end of the adjusting assembly, and a switch assembly configured to mount on the handle assembly; and a motor-housing assembly adapted to provide a cutting driving force and configured to detachably disposed in the handle assembly; and a connecting assembly adapted to connect the cutting assembly with the motor-housing assembly.
• the motor-housing assembly comprises a housing.
• a motor, a battery, a button, and an electric circuit are electrically connected in turn and disposed in the housing.
• the motor has a first end coupled with the cutting assembly via the connecting assembly, and the button has a top end contacted with the switch assembly.
• a soft starter for the motor a voltage regulating module, and a charging module for the battery are disposed on the electric circuit.
• Fig.5 is a left side, cross-section view of the adjusting assembly of the skin removing device according to an embodiment of the present disclosure
• Fig.6 is a schematic view of the adjusting assembly of the skin removing device according to an embodiment of the present disclosure
• Fig.9 is a cross-section of the skin removing device formed without the motor-housing assembly according to an embodiment of the present disclosure.
• the terms “mounted,” “connected,” “coupled,” and “secured” and variations thereof are used broadly, such as rigid attachments, also movable attachments, or integrated attachments; mechanical connections, also refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, or structures having their interiors connected.
• mechanical connections also refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, or structures having their interiors connected.
• the skin removing device may comprise: a cutting assembly 100 adapted to cut skin, an adjusting assembly 200 adapted to adjust a cutting area so as to obtain different size of skin, a connecting assembly 300, a motor-housing assembly 400, and a handle-switch assembly.
• the handle-switch assembly provides a gripping and controlling area for users. Users may hold the handle-switch assembly in hand and control the operation the skin removing device.
• the operation of the skin removing device comprises the following steps: placing the skin removing device on the skin, the angle between the skin removing device and the skin being between 30 degrees to 45 degrees; pressing the switch assembly 600 of the skin removing device; and moving the skin removing device along the skin.
• the skin is elastic and may pass through the skin cutting groove in the cover plate 16 and reach the cutting blade 17.
• the cutting blade 17 may keep on contacting with the skin, and in that way, skin may be removed or cut.
• the removed skin may pass through the gap between the cutting blade 17 and the pressing plate 15, then stretch out along the curved front edge of the cutting blade 17, and then the removed skin can be obtained by a plier.
• the adjusting assembly 200 further comprises two eccentric adjusting pins 14.
• the two eccentric adjusting pins 14 are disposed at two opposite sides of the pressing plate 15. In that way, a deflexion of the pressing plate 15 which may be caused by the pressure on the eccentric shaft 12 can be effectively avoided.
• the handle assembly 500 comprises a handle 22, and an end cover 28 mounted on a second end of the handle and configured to open or close the handle.
• the handle 22 has a first end fixedly coupled with the connecting support 6, so as to fixedly couple the handle assembly 500.
• the end cover 28 is disposed at the second end of the handle 22, and the handle assembly 500 can be opened or closed via the end cover 28.
• the motor-housing assembly 400 is disposed in the handle 22.
• the handle assembly 400 may be opened by removing the end cover 28, then the motor-housing assembly 400 may be taken out of the handle assembly 400 and recharged, while the remaining elements of the skin removing device may be disinfected.
• the motor-housing assembly 400 may be inserted into the handle 22, and the end cover 28 is closed to seal the handle 22.
• the protrusion rod 27 has a first end extended into the handle 22 so as to contact with the button 3, and a second end extended to out of the switch support 25 so as to contact with the switch pressing piece 20.
• the switch support 25 may further comprise an upper cover 24. The upper cover 24 may prevent the spring 26 from moving out of the switch support 25.
• an end portion of the switch pressing rod 23 is formed with a slide groove.
