Referring to fig. 1 to 4, an ear canal scraper is provided with a central plane.

The ear canal scraper includes a grip operating body 100, a cutter head 200, a blade 300 and a protection structure 400.

The grip operation body 100 is provided with a central axis that coincides with a central plane (the dotted line in fig. 4 indicates the central plane). The grip operation body 100 includes a handle 110 and an extension rod 120, and the handle 110 and the extension rod 120 are fixedly connected. Both the handle 110 and the extension pole 120 extend along a central axis. The handle 110 is a cylindrical structure, the axis of the handle coincides with the central axis, the diameter of the handle 110 is about 6-10mm, the length of the handle is 6-10cm, and the outer peripheral surface of the handle 110 is provided with anti-skid grains. The extension rod 120 is a round rod-shaped structure, the extension rod 120 is used for connecting the handle 110 and the tool bit 200, so that the tool bit 200 can extend into the ear canal, and the diameter of the extension rod 120 is about 2.5 mm.

The cutter head 200 is provided at the front end of the extension pole 120. The cutting head 200 has an extending path, the extending path coincides with the central plane, the extending path is arc-shaped, the arc-shaped opening of the extending path faces the central axis, and the cutting head 200 is arc-shaped as a whole (in other embodiments, the shape of the cutting head 200 may also be a three-dimensional structure with a wavy shape or a multi-segment bending shape extending along the extending path), so that the cutting head 200 can adapt to the curvature of the external auditory canal. The cutting head 200 is gradually separated from the central axis away from the holding operation body 100, and the inclined angle between the cutting head 200 and the central axis is about 45 degrees, so that the cutting head 200 can be more easily inserted into the ear canal of a patient. The cutter head 200 comprises a mounting seat 210 and a sealing cover 220, the mounting seat 210 is fixedly connected with the front end of the extension rod 120, and the sealing cover 220 is detachably and fixedly connected through a clamping structure. The front end of the mounting base 210 is provided with a hemispherical smooth top end 211. The mounting seat 210 is provided with a mounting groove 212, and a limiting protrusion 213 is arranged in the mounting groove 212.

The blade 300 is provided with a limiting groove 320, the limiting groove 320 is a through groove, the limiting groove 320 corresponds to the limiting protrusion 213 one by one, the limiting groove 320 penetrates through the blade 300 along the thickness direction of the blade 300, and the limiting groove 320 is matched with the limiting protrusion 213 to limit the blade 300. The blade 300 is provided with an arc-shaped sharp edge 310, the sharp edge 310 is arranged at the edge of the blade 300 far away from the cutter head 200, and the arc-shaped opening of the sharp edge 310 faces the central axis. The sharp edge 310 and the central plane are arranged at an included angle of 45 degrees, and in order to ensure that the cutter head 200 extends into the external auditory canal, the sharp edge 310 and the longitudinal axis of the external auditory canal form an included angle of 45 degrees, so that the sharp edge 310 can play a good scraping effect on the ear hair.

The protective structure 400 is a grid structure, the protective structure 400 wraps the sharp edge 310, and the grid-shaped protective structure 400 forms a plurality of cutting grooves for the sharp edge 310 to contact with the hair of a patient. The protection structure 400 is relatively fixed with the blade 300 and the cutter head 200 through the compression of the mounting seat 210 and the cover 220, and the protection structure 400 exceeds the sharp edge 310 by about 0.2mm, so that the protection effect is achieved, and the blade 300 is prevented from directly cutting the skin of a patient.
