Objective

2

To explore the application value of biomaterial breast model combined with traditional clinical teaching methods in the training of minimally invasive breast surgery.

Methods

2

A total of 50 physicians who studied at the Thyroid and Breast Surgery Department of The First Affiliated Hospital of Air Force Medical University from March to December 2021 were selected as the research subjects and divided into the experimental group and the control group. The training time was one week

with three modules

namely

the study of Doppler ultrasound system and ultrasound theory

the study of the operating system for minimally invasive breast surgery

and the clinical observation and practice of minimally invasive breast surgery. Additionally

physicians in the experimental group practiced the surgical skills by using the biological material breast model. After the training

the assessment of breast minimally invasive surgery was performed

and the differences of minimally invasive operation and subjective evaluation of the two groups of physicians were analyzed. SPSS 22.0 was used to conduct independent-samples

t

-test and Chi-square test.

Results

2

The time spent on breast mass localization

rotary cutter localization and residual rates of breast mass in the experimental group were (4.12±1.05) min

(12.12±2.61) min and 40%

respectively

and the corresponding results of the control group were (6.68±1.97) min

(15.32±2.89) min and 72%

which showed statistically significant differences between the two groups (

P

<

0.05). At the same time

the physicians in the experimental group were better than the control group in terms of self-evaluation of operational proficiency and clinical operation confidence.

Conclusion

2

Compared with the traditional teaching method

the biomaterially simulated breast model combined with traditional teaching has significant advantages. It is an efficient teaching aid in the training and teaching of breast minimally invasive surgery

and plays an important role in the training of breast surgeons.
