An internal examination involves sticking a finger inside the vagina or anus, not putting your whole hand inside. 1. Internal vaginal examination: the doctor puts the index finger and the middle finger into the vagina of a woman, before doing so, the doctor will wear sterile gloves, then dip the finger in a small amount of sterile soap, and touch the vagina to clarify the elasticity of the vagina, the degree of smoothness, and the presence of any swelling. During the internal examination, the finger pushes the uterus inside the vagina to the back and upward, so that the uterus moves forward, and the other hand presses the upper pelvic position, so that the uterus is sandwiched between the two hands, so that the uterus can be understood in terms of its size and position. 2. Anal endoscopy: After the doctor puts on sterile gloves, he puts one finger into the anus and touches the rectum, and the other hand touches the abdomen. During the examination, the patient should relax, do not be too nervous and cooperate with the doctor.
