The conveying device employs the control device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a delivery device and a control device. Background technique [0002] In recent years, some scholars have begun to try to use endovascular exclusion to treat aortic disease, and related chimney and window techniques have begun to achieve some results, and the results are encouraging. However, due to the particularity of the anatomical structure of the arch of the aorta and the complexity of hemodynamics, it is necessary to use a delivery device to deliver the stent to be implanted in the body. [0003] Traditional delivery devices generally use hollow inner tubes and outer tubes that are nested with each other. The hollow part of the inner tube is convenient for the guide wire to pass through the tube during surgery, and the vascular stent is arranged between the inner tube and the outer tube. Due to the structural defects of traditional delivery equipment, the release p...
