Abstract

Provided are skin incision instrument to efficiently incise minimal portions and a method for incising skin with the skin incision instrument. The skin incision instrument according to the present invention comprises a holder, a needle, a needle drive unit, a skin expander, and a reader, wherein the needle and the skin expander are mounted at an end of the holder, the needle drive unit is mounted in the holder, the needle drive unit is capable of forming an incision portion in a skin caused to contact the end of the holder by moving the needle, the skin expander is capable of expanding skin at both sides of the linear incision portion away from the linear incision portion in a direction to expand the linear incision portion, and the reader determines position of the skin expander by rotating the skin expander around the needle in order to adjust an angle to 45 degrees or more and 90 degrees or less wherein the angle is a smaller angle among angles formed by the representative line connecting both ends of the linear incision portion and the direction to expand skin at both sides of the linear incision portion with the skin expander, and minimal portions are efficiently incised.

Claims

1. A skin incision instrument comprising:

a holder;

a needle;

a needle drive unit;

a skin expander; and

a reader;

wherein

the needle and the skin expander are mounted at an end of the holder,

the needle drive unit is mounted in the holder,

the needle drive unit is capable of forming linear incision portion in a skin caused to contact the end of the holder by moving the needle,

the skin expander comprises a first skin expander and a second skin expander,

the first skin expander and the second skin expander are positioned around the needle which is a symmetry axis,

the first skin expander and the second skin expander are capable of expanding skin at both sides of the linear incision portion away from the linear incision portion and expanding the linear incision portion in a direction to expand the linear incision portion,

the first skin expander and the second skin expander are capable of rotating around the needle which is a rotation axis, and

the reader is capable of reading a direction of the linear incision portion.

2. The instrument according to claim 1, wherein said skin expander operates in association with said reader.

3. The instrument according to claim 1, wherein said reader comprises an imaging unit, a light source, and a calculating unit.

4. The instrument according to claim 1, wherein said reader comprises a mechanism to read a direction of said linear incision portion formed by slightly opening said incision portion with said skin expander.

5. The instrument according to claim 1, wherein said holder comprises a mark indicating a direction of said blade surface.

6. A blood test kit comprising the instrument according to claim 1.
