Abstract:
Objective:To explore the effect of preliminary application of a surgical microscope with a measuring system in measurement of the outer diameter of blood vessels in the super-microsurgical model of chicken wing.Methods:From November 2022 to January 2023, 12 chicken wing models were established by having the main blood vessels of chicken wings dissected and separated. Outer diameter of blood vessels were measured by the surgical microscope with an installed measuring system and a digital vernier calliper. Results of the 2 measuring methods and measuring time were compared. SPSS 26.0 was used for statistical analysis of the data. The comparison between the 2 measuring methods with continuity data consistent with the homogeneity of normal distribution variance was performed by paired t test, and expressed by Mean ± SD. The difference between the 2 measuring methods was statistically significant ( P<0.05). Results:Results measured by the microscope with a measuring system and a digital vernier calliper were 1.29 mm± 0.08 mm and 1.28 mm± 0.07 mm for chicken wing brachial artery, 1.11 mm± 0.11 mm and 1.09 mm ± 0.11 mm for radial artery, 0.98 mm± 0.09 mm and 0.99 mm± 0.12 mm for ulnar artery, 0.63 mm ± 0.06 mm and 0.64 mm± 0.07 mm for dorsal metacarpal artery, and 0.39 mm± 0.06 mm and 0.40 mm± 0.09 mm for palmar artery, respectively. No significant difference was found between the 2 measuring methods ( P>0.05). The time of measurement for the 2 measuring methods was 5.90 s± 1.12 s and 8.86 s± 1.74 s, respectively. The time for the microscope with a measuring system was less, with statistically significant difference ( P<0.05). Conclusion:It is accurate, convenient and intuitive to use a surgical microscope installed with a measuring system to measure the outer diameter of tinny vessels. It is worth to popularise and apply the surgical microscope equipped with a measuring system in super-microsurgery.
