Thanks a lot for your help! You put me on the right track. I kep digging and actually found two more possible options, they are very similar to your suggestion.
REGULAR BLOCK TIME
The term “regular block time” refers to a surgeon’s allocated OR time for performing elective cases. We use the term “overflow block time” for OR time for all those cases of the surgeon’s group that cannot be performed in the regular block time of each surgeon in the group.
ALLOCATED BLOCK TIME
Scheduling surgical time is allotted in block segments by surgeon or service. All surgical procedures will be scheduled into allocated block times. Cases, which exceed the available block time, must be placed on-call.

So I think I am going to use allocated block time for the first one, and incision-to-closure time for the second one.
Thank you, thank you, thank you!
