Abstract
The utility model discloses a gun-type internal radiotherapy particle implantation device, which comprises a gun-type handle and a particle chamber. The particle bullet bin is provided with a run-through push rod channel and the top of the particle bullet bin is provided with a particle magazine. The front wall of the particle bullet bin is fixedly provided with a general interface for puncture needles. The rear wall of the particle bullet bin is provided with a push rod conduit. The axial directions of both the general interface for puncture needles and the push rod conduit are concentric with the axis of the push rod channel. The device also comprises two cylindrical sliding rails parallel to the axis of the push rod conduit, a movable bracket, a particle bullet bin moving structure and a blood return release structure. The particle bullet bin moving structure consists of a hand wheel, a pair of bevel gears, a screw and a first sliding block arranged inside the helical groove of the screw.
