This invention discloses an insertion-type catheter fixation device, belonging to the field of medical tool technology. It solves the problem that existing fixation devices cannot prevent changes in the insertion depth of the catheter due to patient movement or bending at joints. The fixation device includes a base, a top cover, and a compression member. The top cover is installed on the base and covers the opening at the top of the base. The compression member is installed inside the base. A protective component is installed at the end of the base. The protective component protects both ends of the base and limits the insertion depth of the catheter, preventing changes in the insertion depth due to patient movement or bending at joints. An installation mechanism is installed at the bottom of the base to assist in the stable fixation of the base and ensure the stability of the fixation device during use.

The application discloses a range shifter, which comprises a multi-dimensional motion support fixed with a treatment bed, the multi-dimensional motion support being provided with a plurality of rotary joints and a plurality of moving joints; and a shifter body installed on the multi-dimensional motion support and movably arranged relative to the treatment bed through the plurality of rotary joints and the plurality of moving joints. In the application, the shifter body is installed on the multi-dimensional motion support, so that the shifter body can move in multiple degrees of freedom relative to the treatment bed through the plurality of rotary joints and the plurality of moving joints in the multi-dimensional motion support, the distance between the geometric center of the range shifter and the isocenter point can be adjusted according to clinical requirements, and then the shifter body can be close to the patient to reduce the beam spot when the target region is close to the organ at risk.
