A surgical stent delivery system (100) and a surgical stent system, wherein a surgical stent (200) includes a main stent (210) and a branch stent (220) that is disposed on the main stent and projects laterally outward from an outer circumference thereof. The surgical stent delivery system (100) includes a main liner (111) and a branch liner (112) disposed on the main liner (111). The branch stent (220) is configured to be sleeved over the branch liner (112), and the main stent (210) is configured to be sleeved over the main liner (111). The branch liner (112) is pivotably disposed on the main liner (111) so as to enable the branch stent (220) to pivot in synchronization with respect to the main stent (210). By arranging a branch liner (112) that is able to pivot with respect to the main liner (111), the branch stent (220) can pivot in synchronization with respect to the main stent (210), thereby facilitating an intraoperative alignment between the branch stent (220) and the left subclavian artery, make implantation easier, avoid increased postoperative complications from too much time spent in mobilizing and anastomosing the left subclavian artery during the open-chest procedure, lower operational difficulties, shorten the overall operation cycle time and widen the scope of suitable patients.
