The invention discloses a delivery assisting device for a vascular interventional
surgical robot. The delivery assisting device comprises a mouth gag and a C-shaped tube, the mouth gag comprises a first C-shaped tube supporting part, a second C-shaped tube supporting part, a
guide tube supporting part and a shuttle type slideway; the first C-shaped tube supporting part is provided with a first C-shaped tube channel, and the
catheter supporting part is located behind the first C-shaped tube supporting part and provided with a
catheter channel; the shuttle-type slide way is arranged at the front end part of the
catheter supporting part and is obliquely arranged towards the side rear part relative to the catheter channel; the second C-shaped
pipe supporting part is arranged behind the side of the shuttle type slide way and is provided with a second C-shaped
pipe channel; in the assembled state, the front end and the rear end of the C-shaped
pipe are fixed to the front end and the rear end of the
robot body, and the C-shaped pipe extends backwards from the front end, penetrates through the first C-shaped pipe channel, is arranged on the shuttle type sliding way in a sleeving mode, penetrates through the second C-shaped pipe channel and extends backwards to the rear end of the
robot body. The C-shaped tube supports the portion of the catheter between the front end outlet of the C-shaped tube and the front end outlet of the catheter channel.
