There is provided an insertion device allowing a doctor to alone perform an operation to insert a medical linear body. The insertion device, operated to insert a delivery wire (104) into a human body (131) through a blood vessel (132), includes a foot switch (41, 46) generating and outputting a signal to control starting/stopping a drive device (1) moving the delivery wire (104) in its longitudinal direction. Furthermore, the insertion device includes an insertion force sensor (60) operative to measure longitudinally compressive force exerted to the delivery wire (104), and a speaker (92) and a display (93) informing an operator of the compressive force measured by the insertion force sensor (60). |

1. An insertion device for inserting a medical linear body into a bodily vessel, comprising:
a drive device operative to move said medical linear body in a longitudinal direction thereof; a foot switch operative for generating and outputting a signal to control starting/stopping said drive device; a medical instrument further comprising a measurement device operative to measure longitudinally compressive force exerted to said medical linear body, wherein the medical instrument comprises a through hole capable of receiving and allowing said medical linear body to pass therethrough and wherein said measurement device includes a sensor operative to sense a degree of a curvature of said medical linear body; and a conversion circuit operative for converting said degree of said curvature of said medical linear body sensed by said sensor into the compressive force exerted to said medical linear body; and a compressive force informing device operative for informing an operator of the compressive force exerted to said medical linear body, wherein said drive device comprises:
a torque generator,a driving roller providing rotational motion by a torque generated by said torque generator,a driven roller providing rotational motion as said driving roller rotates,a speed reducer posed between said torque generator and said driving roller, and receiving the torque from said torque generator, reducing the torque in speed, and outputting the torque reduced in speed,a housing surrounding an internal space of the drive device, wherein said housing comprises a partition wall sectioning the internal space of the housing into a first space accommodating the driving roller and the driven roller therein and a second space accommodating the torque generator and the speed reducer therein, wherein the housing comprises a securing portion for securing at least a portion of the medical instrument within the housing, anda rotary unit operative for transmitting the torque from said speed reducer to said driving roller, said driving roller and said driven roller having a rotation surface and a rotation surface, respectively, cooperating to pinch said medical linear body, wherein the partition wall of said housing comprises a hole for receiving and passing said rotary unit therethrough, said hole having an inner circumferential surface provided with a seal in contact with an outer circumferential surface of said rotary unit and sealing an interior of the second space of said housing externally. |
