The present invention relates to a technique about a tissue cutting device which cuts a tissue material. The technique for the tissue cutting device which can reuse a cutter by converting one blade part to another blade part of the cutter when the blade part of the cutter is worn out over a long period of time of a tissue material cutting operation, and extend life expectancy, thereby improving productivity and economical properties. The main structure of the present invention according to the present invention comprises a cutting drum in which a plurality of cutting blades is individually fixed to jigs and which receives driving force of a motor to rotate; a cutter drum which is installed to be close to and parallel with the cutting drum and receives the driving force of the motor to rotate; multiple pairs of the jigs which are fastened to the cutter drum, comprise chucking grooves in the axial direction of the cutter drum, and are coupled to each other; and a cutter which is inserted into the chucking grooves of the jigs and comprises multiple blade parts and multiple surfaces. |
