The invention discloses a cutter for
cutting gluteal
muscle contracture fascia. The cutter includes an adjustment column, a pair of clamping frames and a pushing knife; each clamping frame has a semi-cylindrical tubular structure, and the two clamping frames are arranged symmetrically; the interior of the adjustment column is hollow, a penetrating strip-shaped groove is arranged in the axial direction of the adjustment column, the width of the strip-shaped groove is the same as the
diameter of each clamping frame, and the clamping frames pass through the strip-shaped groove of the adjustment column; an adjustment
handle is arranged in the adjustment column, the adjustment
handle can rotate axially along the adjustment column, and the adjustment
handle and the adjustment column are respectively slidingly connected with the clamping frames; and the length of the pushing knife is smaller than the length of each clamping frame, and the pushing knife is perpendicular to a cross section between the two clamping frames and is slidingly connected in the tube walls of the clamping frames. Compared with the prior art, the cutter effectively reaches a predetermined position under minimally
invasive surgery, the cutter has a structure easy to operate, and the pushing knife is not easy to rotate, has high stability, and does not hurt sciatic nerves at the rear; cutters with different modelscan be selected according to the thickness of the
fascia, and the adaptability is strong; and an intraoperative incision is small, and a postoperative incision is beautiful.
