Perhaps you should try some spelling variations:
"surgical measures" » "surgical exposures", "surgical failures", "surgical masks"
"surgical gesture" » "surgical gestures", "musical gesture", "musical gestures"
"surgical suture" » "surgical sutures", "surgical site", "surgical gestures"
"surgical suite" » "surgical suites", "surgical site", "surgical system"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("surgical suture") OR ("surgical suite"))) OR ((("surgical gesture") OR ("surgical measures")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"surgical suture\") or (\"surgical suite\"))) or (((\"surgical gesture\") OR (\"surgical measures\"))))".
• Removing quotes may allow a broader search: (((( surgical suture ) or ( surgical suite ))) or ((( surgical gesture ) OR ( surgical measures )))).
• Adding a wildcard symbol may retrieve word variants: (((("surgical suture") or ("surgical suite"))) or ((("surgical gesture") OR ("surgical measures"))))*.
