Retractor for spinal surgery

Abstract

The present invention relates to a retractor for spinal surgery, which allows an operator to obtain a maximum surgical view with a minimal incision by easily widening a skin incision site of a patient while minimizing the surgical incision area. To this end, the retractor for spinal surgery includes: a first retractor body, which has a semi-cylindrical shape and in which a space is formed to accommodate a plurality of sleeves, and simultaneously, a lower end thereof is inserted into a skin incision site; a second retractor body, which has the same shape as that of the first retractor body and is rotatably coupled to the first retractor body, and thereby accommodate the sleeves along with the first retractor body; and a pair of hinge units, which are mounted on an upper part of the first retractor body and the second retractor body, and in which an end of the first retractor body and an end of the second retractor body are hinged together by a connecting pin.

Dependencies are inferred from the claim text.
