The present invention provides an intraoperative stent delivery system and an intraoperative stent system. The intraoperative stent includes a main body stent and a side branch stent arranged on the main body stent and extending outward. The intraoperative stent delivery system includes a main body an inner lining and a side branch inner lining arranged on the main body inner lining, the side branch bracket is configured to be sleeved on the side branch inner lining, the main body bracket is configured to be sleeved on the main body inner lining, and the side branch The inner liner is oscillatingly arranged on the main body inner liner to synchronously drive the side support bracket to swing relative to the main body support. In the present invention, by setting the side branch lining that can swing relative to the main body lining, the side branch stent can be swayed synchronously relative to the main body stent, which facilitates alignment and easy implantation of the side branch stent and the left subclavian artery during operation, and avoids thoracotomy The time of freeing and suturing the left subclavian artery in the operation is too long, which increases postoperative complications, reduces the difficulty of operation, shortens operation time, and expands the scope of surgical indications.
