step two, a first hollow cavity (701), a second hollow cavity (703) and a third hollow cavity (704) are formed in the rod body (1), the first hollow cavity (701) is communicated with the second hollow cavity (703) and the third hollow cavity (704), a guide pin is inserted into the first hollow cavity, an upper connecting port (702) is formed in one side of the first hollow cavity (701), and the first hollow cavity (701) and the second hollow cavity (703) are connected in a switching mode;

step three, a connecting column (801) is fixedly connected to one end of the rod body (1), the top end column (802) is fixed through the connecting column (801), the top end column (802) is fixedly connected to one end of the connecting column (801), a plurality of openings (803) are formed in the top end column (802), one end of the connecting column (801) can be connected with the blade (11), the top end column (802) can be replaced by the blade (11), the openings (803) can be changed into the blade (12), when the top end column (802) is changed into the blade (11), the connecting column can be connected through a welding layer (10), the blade (11) is sharp, the rest of the connecting column have no sharp edge and no crack, the blade (11) is divided into five spiral blades by the blade (12), the spiral angle is 17 degrees, and the blade width is 0.5 mm;

fourthly, a hollow groove (901) is formed in the rod body (1), a first hollow opening (902) and a second hollow opening (903) are formed in the hollow groove (901), a fourth hollow opening (904) is formed in one end of the second hollow opening (903), the hollow groove (901) is formed in the base (401), the blade (11), the top end column (802) and the tail end column (6) and is a basis for forming the hollow openings, and the first hollow opening (902) and the second hollow opening (903) are communicated with each other;

step five, a connecting piece (5) is fixedly connected to one side of the base (401), namely, a tail end column (6) can be fixedly connected to one end of the connecting piece (5), so that a connecting measure is formed between the tail end column (6) and the base (401);

and step six, the first middle hollow hole (701), the second middle hollow hole (703), the third middle hollow hole (704), the fourth middle hollow hole (904) and the fifth middle hollow hole (13) form a whole, the interior of the whole is communicated, the diameters of the whole are different, the inside of the whole is in a diameter range, the diameter of the whole is in a diameter range, the inside of the soft rod reamer is in a structure which is internally penetrated, and a wire guide pipe is arranged inside the soft rod reamer.
