microscope，and then by adding and reducing weight to Vicryl suture at room temperature，the axial elongation is
measured by stretching method. The stress - strain curve，tensile strength 518. 824 MPa，elongation at break
14.087%，yield strength 76.8 MPa，yield strain 1.57% and Young's modulus 81.505 MPa have been measured.
The stress-strain hysteresis loop of Vicryl suture is also obtained.
Key words： stretching method; suture; mechanical property
