Cannular for percutaneous foraminotomy and Cutting device for the percutaneous foraminotomy

摘要

The present invention relates to a cannula for percutaneous vertebral intervertebral dilatation and an intervertebral extension device having the cannula. The cannula includes: an outer tube fixed to the casing; An inner tube provided inside the outer tube; An endoscope maintenance operation part supported by the casing and supporting the endoscope camera; And an adapter unit fixed to the casing and supporting the rotating shaft.As described above, since the rotating shaft having the cutting blade is rotated at a high speed, it is possible to perform an effective operation by changing not only the adhesive tissue that presses the nerve but also the nipple bone, and furthermore, It is possible to quickly discharge the cut material that has been formed and to shoot the treatment situation in real time by using an endoscope camera to optimally control the rotation speed and position of the cutting blade part and to continuously wash the lens part of the endoscope camera by injecting saline solution As well as the focus of the endoscope camera in a fixed state can be adjusted, so that a clear image can be obtained at all times, thereby enabling a convenient and highly effective operation.;
