Primary Outcome Measures

Name	Time	Method
Usage of Morphine, Post Surgery	0 hour to 48 hours after IP administration	Change in the amount of morphine use (in milligrams) by subjects in each treatment group for a 48 hour period post IP administration

Secondary Outcome Measures

Name	Time	Method
the Sum of Pain Intensity Differences in Pain Score Over 6、12、24、48 、12-24、24-48 Hours under moving condition	48-hours	Pain intensity will be evaluated using an 11-point (0-10) Numeric Rating Scale (NRS), with higher numbers indicating a higher pain intensity, administered over 48 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (48 hours) to yield values on the 0-10 NRS.
Usage of Morphine, Post Surgery at other intervals	0 hour to 24 hours after IP administration ；24 hours to 48 hours after IP administration	Change in the amount of morphine use (in milligrams) by subjects in each treatment group for 0-24 hours after IP administration.Change in the amount of morphine use (in milligrams) by subjects in each treatment group for 4-48 hours after IP administration.
the Sum of Pain Intensity Differences in Pain Score Over 6、12、24、48 、12-24、24-48 Hours under static condition	48-hours	Pain intensity will be evaluated using an 11-point (0-10) Numeric Rating Scale (NRS), with higher numbers indicating a higher pain intensity, administered over 48 hours. Time weighted average change from baseline is calculated using the following: time weighted sum of pain intensity differences (SPID) divided by a constant (48 hours) to yield values on the 0-10 NRS.
Time to First Dose of Rescue Analgesia	0 hour to 48 hours after IP administration	Time to first rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.
Frequency of Doses of Rescue Analgesia Utilized Per Subject， total consumption of morphine Rescue Analgesia Utilized Per Subject	0 hour to 24 hours after IP administration ；24 hours to 48 hours after IP administration ；0 hour to 48 hours after IP administration	Rescue analgesia was available to subjects with inadequately controlled pain upon request.
Total press times of PCA pump and effective press times of PCA pump	0 hour to 24 hours after IP administration ；24 hours to 48 hours after IP administration ；0 hour to 48 hours after IP administration	Read and record the press times and effective press times from PCA
Participant ' satisfaction score for analgesia treatment	48-hours	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.
Proportion of subjects who did not receive Rescue Analgesia	0 hour to 24 hours after IP administration ；24 hours to 48 hours after IP administration ；0 hour to 48 hours after IP administration	Proportion of rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.
Investigator satisfaction score for analgesia treatment	48-hours	Postoperative analgesia was evaluated by investigators. The scale ranges from 0 to 10, with 0 being dissatisfied and 10 being very satisfied
