Objective:To explore the current situation of professional identity of intern nursing students in Shandong Province, to analyze the potential characteristics of different categories of intern nursing students' professional identity, and to provide reference for formulating relevant intervention programs.Methods:From September to October 2023, using convenient cluster sampling, selected nursing students from different regions of Shandong Province colleges and universities as the research objects, a total of 1298 questionnaires were released and recovered, with 1221 valid questionnaires, and the effective recovery rate of questionnaires was 94.07%. General demographic data was collected, and information on nursing students' professional identity was investigated with the Nursing Students' Professional Identity Questionnaire, the Work Readiness Scale, and the Feedback Seeking Behavior Scale. Latent potential profiles of nursing students' sense of professional identity were analyzed by Mplus 8.3 software, and the best-fitting model was selected by the test of fitness and difference. The χ 2 test was used for comparison between groups of count data, analysis of variance (ANOVA) was used for comparison between groups of measure data, and the effects of each factor on different potential profiles were analyzed by multivariate logistic analysis. Results:A total of 1221 intern nursing students were 984 (80.6%) females and 237 (19.4%) males, aged (21.12±2.96) years old, with a total score of (64.23±14.99) for nursing students' professional identity. Nursing students' professional identity was divided into 3 categories: 98 (8.0%) in the low identity group, 624 (51.4%) in the medium identity group, and 496 (40.6%) in the high identity group. The gender, region, age, work readiness scores and feedback seeking behavior scores of nursing students in different categories were different, and the differences were statistically significant ( P<0.05). Compared with the high identity group, the nursing students in the low identity group were more likely to be included in the high identity group ( OR=0.390, 0.167, P=0.005, 0.006) with higher work readiness and better feedback seeking behavior. Compared with the high identity group, the higher work readiness and non-Jinan areas of the medium identity group were more likely to be included in the high identity group ( OR=0.597, 1.470, P=0.011, 0.012). Compared with the medium identity group, the more feedback seeking behaviors of the low identity group were more likely to be included in the medium identity group ( OR=10.411, P<0.001) . Conclusion:The level of professional identity of intern nursing students can be classified into 3 categories, and nursing administrators can improve work readiness and increase feedback seeking behaviors according to the potential characteristics of the different types to enhance the professional identity of nursing students.

In recent years, robotic surgery technology has advanced rapidly and is now widely applied in general surgery, urology, and other fields. As spine surgery advances toward minimally invasive, endoscopic, and intelligent approaches, the development of spinal endoscopic surgery robots has become imperative. Current robotic-assisted spine surgery systems offer significant advantages, such as improved accuracy in positioning, enhanced precision in needle placement, reduced radiation exposure, and shorter operative times, etc. However, spinal endoscopic robotic technology is still in its initial development stage and faces limitations such as optical navigation. In the future, the integration of optical and electromagnetic navigation, combined with 3D imaging and robotic technologies, will greatly improve the precision of spine endoscopic surgery. With continued advancements in technology, including the incorporation of artificial intelligence and telemedicine, spinal endoscopic surgical assistant robots are expected to play an increasingly important role in spine surgery, offering promising prospects for development.
