Description

Preparation skin knife

This utility model relates to a kind of the operation and prepares the preparation skin knife of usefulness, belongs to the operation medical apparatus and instruments.

At present the preparation skin knife that uses all adopts common shaver, and blade, knife rest are rectangle, because four angles are the right angle, and the little and complex region of skin, particularly department of obstetrics and gynecology, Pediatrics Department, the department of eye that easily scratches fold and uneven position during preserved skin.And easily press from both sides hair between knife rest and the blade.

The purpose of this utility model is to overcome the weak point in the background technology and a kind of hair that do not press from both sides is provided, and is difficult for scratching the preparation skin knife of the unequal complex region skin of fold.

The purpose of this utility model be achieved in that it be on the basis of original shaver, carry out improved, it is made up of handle, interior knife rest, outer knife rest, blade, blade places between interior knife rest and the outer knife rest, double-screw bolt on the outer knife rest passes blade and interior knife rest is fixed on the handle, interior knife rest and outer knife rest one side are ellipse garden shape, the blade of blade one side also is ellipse garden shape, and it is consistent with the radian of interior knife rest and outer knife rest, and the ellipse garden of knife rest shape one side is provided with opening outside.

This utility model is compared with background technology has following advantage:

1, because the sword of inside and outside knife rest and blade one side is ellipse garden shape, the knife rest of opposite side, blade, two angles of blade are to meet at right angles, therefore, the little of fold injustice and around complex region such as femoribus internus, ear, the umbilicus, during uneven place such as nose skin preserved skin, use ellipse garden shape blade one side, be difficult for scratching skin and cause infection, solved the problem of department of obstetrics and gynecology, Pediatrics Department, department of eye preserved skin difficulty, the bigger and smooth position of area then uses the straight side of blade to carry out preserved skin;

2, since outside the ellipse garden of knife rest shape one side be provided with opening, thereby the Mao Buhui that scrapes in the preserved skin process is clipped on the preparation skin knife, and is easy to use, easy to clean.

Description of drawings is as follows:

Fig. 1 is this utility model structural representation;

Fig. 2 is this utility model left view.

Among the figure: outer knife rest (1), blade (2), interior knife rest (3), double-screw bolt (4), handle (5), opening (6).
