Referring to figs. 1 to Fig. 4, this is the embodiments of the present invention, specifically:
A kind of attraction hoe scaler of multi-directionally removing, including being in vertically arranged stripping rod 1, the stripping rod 1
Upper end is connected with cutter hub 2, and for the cutter hub 2 in vertically arranged, described cutter hub 2 in flat-shaped, the edge of the cutter hub 2 is in arc
Shape, the edge of the cutter hub 2 are equipped with blade 3, and the blade 3 is arranged along the edge of cutter hub 2, on the stripping rod 1
The side wall surface in portion is connect with the leading flank of cutter hub 2, and the junction of the stripping rod 1 and cutter hub 2 is close to a left side for 2 leading flank of cutter hub
Side, so that stripping rod 1 and cutter hub 2 are in p-shaped shape in forward sight, the upper surface of the stripping rod 1 is equipped with suction port 11, is removing
It is in the first vertically arranged attraction channel 12, the upper end of first attraction channel 12 and suction port 11 that the inside of bar 1, which is equipped with,
Connection, the lower end of the stripping rod 1 are connected in vertically arranged handle body 4, and the inside of the handle body 4 is equipped in perpendicular
To the second attraction channel 41 of setting, the upper end of second attraction channel 41 is connected to the lower end of the first attraction channel 12.
By being in flat-shaped cutter hub 2, for blade 3 along the setting of the edge of the arc-shaped shape of cutter hub 2, stripping rod 1 and cutter hub 2 are in p-shaped in forward sight
Shape can be moved forward and backward along ear canal and be removed, and existing scalpel can only individually be moved along and be removed, or individually
Movement is removed backward, and the technical program is by the overall structure in p-shaped shape, so that scalpel all can be right when being moved forward and backward
Position is removed in ear canal accordingly to be removed, so that multi-directionally is removed, improves the use scope of scalpel, avoids frequency
Numerous replacement scalpel, the second attraction channel 41 in vacuum extractor and handle body 4, first in stripping rod 1 inhale at the time of surgery,
Draw the connection of channel 12, bleeding, bits body is attracted by the suction port 11 of the upper surface of stripping rod 1, doctor can operate in surgical cut
When side cutting edge attract, remain that visual area is clear, so reduce operation time；By the edge of the arc-shaped shape of cutter hub 2 with
The location contacts of removing, so that the uniform force between blade 3 and removing position, compared with the blade of existing linear, arc
The blade 3 of shape makes the point pressure of each contact uniform, to improve the success rate of operation.
It is further used as preferred embodiment, the section triangular shape of the blade 3.Cutter hub 2 ear canal forward
It is mobile or backward mobile when being cut, so that blade 3 is consistent to position peeling effect to be stripped in ear canal, improve operation
