Background

Ovary, anatomical name. Located in the female pelvic cavity, are paired parenchymal organs. Belongs to female gonad, and is in flat oval shape, and comprises an inner side surface, an outer side surface, an anterior edge, a posterior edge, an upper end and a lower end. The lateral surface is pasted on the side wall of the pelvic cavity and is positioned at the included angle between the internal iliac part and the external artery starting part, and the medial surface faces the uterus; the upper end is connected with the pelvic cavity wall by an ovary suspensory ligament, and the lower end is connected with the uterus by an ovary inherent ligament; the posterior margin is free and the anterior margin has mesenteric attachments with vascular, lymphatic, and neural access. Its size and shape changes with age: in the young girl stage, the surface is smooth; after puberty, due to repeated ovulation, scars and unevenness are formed on the surface; the ovary in the sexual maturity stage is the largest, the length is 2.5-5.0 cm, the width is 1.5-3.0 cm, and the thickness is 0.6-1.5 cm. After menopause, the volume is significantly reduced, while in older women, the length, width and thickness are all only about 0.5 cm. Its main functions are to produce and discharge egg cells, and to secrete sex hormones to promote and maintain the development of female sexual characteristics. Generally, the left and right ovaries alternately discharge mature ova monthly.

Ovarian tumors refer to tumors that occur in the ovary. It is one of the common tumors of female genitalia. Ovarian malignancies are also the most mortality tumors among gynecological malignancies. Although great progress has been made in recent years both in the basic research and clinical diagnosis of ovarian malignancies, unfortunately, the 5-year survival rate has not improved significantly.

In the present stage, the use of the micro ovarian tissue biopsy equipment has certain defects, the use stability is not good, and secondary damage is easily caused.
