Morphology
This is a straightforward adjective + noun composition: 'operative' (relating to surgical procedures) + 'field' (an area or space) yields an area exposed for surgery. The meaning follows normal compositional patterns and the sense of 'field' as a physical area is cross-linguistically common, so a learner who knows the constituents would readily infer the MWE's meaning.
Etymology
Operative field uses operative, meaning about an operation, and field, meaning a clear area for work. It gives the simple image of a clean, open part of the body that a surgeon works on, so the phrase means 'the area of the body that is exposed for a surgical procedure'.
