What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
the Sum of Pain Intensity Differences in Pain Score Over 24 Hours	Pain intensity will be evaluated using an 11-point (0-10) Numeric Pain Rating Scale (NPRS), with higher numbers indicating a higher pain intensity, administered over 24 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (24 hours) to yield values on the 0-10 NPRS.	24-hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
the Sum of Pain Intensity Differences in Pain Score Over 6、12、12-24 Hours	time weighted sum of pain intensity differences (SPID) divided by a constant (6、12、12-24 hours) to yield values on the 0-10 NPRS.	6-hours、12-hours、12-24 hours
Time of first use of remedial analgesic medication	The first time to use remedial analgesic medication for injection	24-hours
Cumulative use of remedial analgesics from 0h to 24h	Cumulative use of remedial analgesic medication	24-hours
Participant ' satisfaction score for analgesia treatment	Participants recalled the postoperative analgesia effect and rated their satisfaction on a scale of 0 to 10, with 0 representing dissatisfied and 10 representing very satisfied.	24-hours
Investigator satisfaction score for analgesia treatment	Postoperative analgesia was evaluated by investigators.The scale ranges from 0 to 10, with 0 being dissatisfied and 10 being very satisfied.	24-hours
