- 摘要：
To allow an operator to sense a subtle feel when inserting a catheter.
SOLUTION: This catheter apparatus 10 is a medical device for inserting the catheter 30 into a tube to be inserted such as a blood vessel 20 by a MANUAL operation. This catheter apparatus 10 includes the catheter 30, a detection section 40, a control section 50 and a feel transmission section 60. When a movable portion 72 of a wire rod 70 inserted into the blood vessel 20 is deformed by coming into contact with some sort of obstacle and the control section 50 amplifies a detection signal by a prescribed amplification factor to generate a motor control signal V consisting of pulse waves based ON the amplified detection signal. In the feel transmission section 60, a stepping motor 66 intermittently actuates a resistance force application member 64 in an X2 direction by the number of times when motor control signals V generated by the control section 50 are input. A sliding section 64b of the resistance force application member 64 thus pushes the wire rod 70 in the X2 direction, so that the operator senses, in his/her fingertips and the resistance force in the inverse direction of the insertion direction.
