摘要： An apparatus for shaving a tap hole surface of a blast furnace or the like wherein efficiency can be improved, and a worker can be freed from physically burdensome work in the vicinity of the lower furnace wall of a blast furnace under high temperature. The apparatus includes a surface shaving unit having smoothing bits, and a rotating mechanism unit that, when the surface shaving unit is pressed against the tap hole surface, rotates the surface shaving unit, by utilizing the pressing force, by a predetermined angle in a predetermined direction substantially parallel to the surface, and holds the surface shaving unit at the rotated position. The rotating mechanism unit eliminates the need for work such that every time a conventional surface shaving unit is separated from the tap hole surface after being pressed against the surface, a worker manually rotates the surface shaving unit by a predetermined angle.

摘要： An exhaust tool (50) includes: a flexible body portion (51) extending over substantially an entire length of a cylindrical shaft (30, 90) of an incision energy device (e.g., ultrasonic coagulation incision device 10 or electrocautery device 80) having an energy generation portion (32) for incision provided at a tip thereof; a pair of holding portions (52) provided to the body portion (51) and configured to hold the cylindrical shaft (30, 90); and a flow path formation portion (54) forming therein a flow path (56) for mist generated from the energy generation portion (32). The exhaust tool (50) is allowed to be attached/detached to/from the cylindrical shaft (30, 90) by the pair of holding portions (52) being opened through bending of the body portion (51).
