PROBLEM TO BE SOLVED: To suppress increase in size of a supporting device for supporting a plurality of surgical instruments while improving flexibility of arrangement of a plurality of surgical instruments. A surgical system (100) is configured to hold a plurality of surgical instruments (1) each having a soft shaft (11) and an end effector (12) and a plurality of soft shafts (11), and from one end to the body of a patient (P). An insertion tube 3 to be inserted into the insertion tube 3, a plurality of surgical instruments 1, and a support device 2 that supports the insertion tube 3. The support device 2 includes a plurality of support portions 23 that respectively support the plurality of surgical instruments 1, a support mechanism 24 configured to integrally support the plurality of support portions 23, and an insertion tube that holds the insertion tube 3. And a holding unit 27.
