  "description_excerpt": "The present disclosure relates to the technical field of medical robots, applicable to master-slave vascular interventional robots, and in particular, relates to a slave-end apparatus for an interventional robot.\n\nMinimally invasive vascular intervention refers to a physician, guided by a digital subtraction angiography (DSA) system, manipulating the movement of a catheter and a guide wire in human blood vessels to treat lesions, so as to achieve the purpose of embolization of abnormal vessels, thrombolysis, dilation of narrow vessels, and the like. At present, interventional therapy has played an important role in the diagnosis and treatment of hundreds of diseases, such as tumor, peripheral vessel disease, great vessel disease, digestive tract disease, nervous system disease, and non-vascular disease. The interventional therapy covers all diseases from the head to the foot of the human body, and has become the first choice for some diseases. Interventional therapy can treat many diseases that cannot be treated in the past or have a poor curative effect without incision of human tissues. In the interventional therapy, the incision (puncture point) only has the size of rice grains. The interventional therapy has the characteristics of no incision, small trauma, rapid recovery and good curative effect, which has been highly valued by domestic and foreign medical circles.\n\nCurrently, minimally invasive vascular intervention-assisting robots have developed rapidly due to the involvement of high-end medical equipment and robotic technology. We have also placed investment in research and development.",
