Abstract
The invention relates to a detachable vertebral plate rongeur. The detachable vertebral plate rongeur is composed of an upper piece, a lower piece, a gill shaft screw and a left rongeur handle. The rear portion of the lower piece is a right rongeur handle which is matched with the left rongeur handle. The right rongeur handle is hinged to the left rongeur handle through the gill shaft screw in an intersecting mode. The front end of the upper piece and the front end of the lower piece are respectively provided with a cutting edge capable of conducting cutting. The upper piece can slide frontwards or backwards along the lower piece. The upper end of the left rongeur handle is provided with an open groove. A hinge pin is arranged at the rear end of the upper piece. The hinge pin is arranged in the open groove. A rotatable limiting block is arranged on the left end face of the left rongeur handle. The limiting block is located at the position of the included angle between the left rongeur handle and the lower piece and is in the shape of a long strip. When the long end face of the limiting block is not in contact with the lower piece, the hinge pin can be disengaged from the open groove. A detachable structure is arranged between the upper piece and the lower piece. Limiting is achieved through rotation of the limiting block. After the detachable vertebral plate rongeur is detached, the whole vertebral plate rongeur can be cleaned and disinfected, blood residues in gaps can be completely removed, and therefore cross infection is effectively avoided.
