With the incidence of cervical cancer in women rising year by year, its impact on the physical and mental health of patients as well as their families is becoming more and more significant. At present, hospitals often use intracavitary radiation therapy, and intracavitary therapy transfer bed as a gynecological oncology intracavitary radiation medical auxiliary device plays an extremely important role. Therefore, for the design of intracavitary therapy transfer beds, the validation of man-machine adaptability can well help to optimize its structure. The paper firstly imports the three-dimensional model of intracavitary therapy transfer bed established in UG software into the ergonomics analysis software Jack; secondly, in the analysis environment, it establishes the human body model that conforms to the body dimensions of patients with cervical cancer as well as the human body model of healthcare workers; then, on this basis, it establishes the simulation model for the patient's posture of using the intracavitary therapy transfer bed as well as for different movements of the healthcare workers in the course of the treatment; finally, it analyzes the stresses of the patient's lower limbs, as well as the waist, back, and upper limbs of the healthcare workers through the simulation and analyzes the comfort of the patients and the healthcare personnel with respect to the different movements of the treatment task. The analysis of the simulation results can verify the rationality of the design of the intracavitary therapy transfer bed and the use of comfort, and at the same time, combined with the results of the analysis of the healthcare worker's working posture, to provide an analysis method for the structural optimization of the intracavitary therapy transfer bed.
