Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a leg support device for lithotomy surgery. Background Art

[0002] During gynecological surgery, the patient needs to take a certain position, mainly to expose the surgical field of view and facilitate the operation. Generally, the bladder stone position is adopted, that is, the patient lies on his back on the gynecological examination bed, with his legs bent and spread apart on both sides of the examination bed. This can fully expose the vulva and pelvic abdomen, so that the condition of the vulva can be fully observed, and it is convenient to do vaginal and abdominal examinations. Gynecological examinations generally observe the development of the vulva and whether there are any abnormalities, then use a vaginal speculum to examine the vagina and cervix, and then perform a bimanual or trimanual examination as needed to understand the condition of the patient's vagina, cervix and pelvic uterine appendages through observation and touch.

[0003] Currently, gynecological operating tables on the market are equipped with leg supports. During surgery, the patient places his legs on the leg supports, and then the patient's calves are fixed with restraints. However, the current leg supports cannot be adjusted according to surgical needs.
