The present invention relates to a body tissue scraping device for operation. The device comprises: a casing; a control unit which generates a control signal; a vibration generating unit which is mounted inside the casing and outputs vibration by receiving the control signal of the control unit; a vibration load which is extended to the outside of the casing while being linked with the vibration generating unit, is inserted into the body to make an extended end part reach a target point in the body, and vibrates in the longitudinal direction while being connected to the operation of the vibration generating unit; a scraper which is closely fixed to the extended end part of the vibration load, vibrates while being in contact with an object to be removed, and removes the object in contact to be removed by scraping the object; and a bending means which bends the scraper in a desired curvature and brings the scraper in contact with the object to be removed closely. The body tissue scraping device for operation of the present invention facilitates the entry into intervertebral foramen by having an active steering means as well as facilitates the setting on an accurate position inside the intervertebral foramen. Also, the removal efficiency is excellent because a scraping plate for scraping the object to be removed is flexible and operates while being in contact with an affected area closely inside the intervertebral foramen. Furthermore, the body tissue scraping device completes removing tissues in a very short period of time by using a motor to vibrate the scraping plate. |
