Abstract: Objective Explore more efficient surgical approaches to bilateral ovarian excision in experimental rats. Method Ordinary ovarian extraction method is to use ophthalmic tweezers to remove the ovaries from the abdominal cavity and then ligate the uterine horns and the ovaries bilaterally, and then use ophthalmic scissors for resection, and finally inject them with penicillin intramuscularly. This method has a small amount of blood oozing, which is prone to intra-abdominal infection. In order to improve the success rate of surgery, after many explorations, this experiment made a tool dedicated to exploring and fixing the ovaries, changing bilateral ligation to unilateral ligation, penicillin intramuscular injection to intraperitoneal injection. Result Comparison experiment showed that the new method was simpler and easier to operate, it was not easy to bleed during the operation, and the success rate of the postoperative operation was higher. Conclusion The new experimental method is simpler to operate and has a higher postoperative success rate.
