Description

technical field

[0001] The invention relates to a pelvic measuring instrument for obstetrics, which belongs to the technical field of medical instruments. Background technique

[0002] When the fetus is delivered from the mother, it must pass through the pelvis. In addition to the soft birth canal composed of the uterus, cervix, vagina and vulva, the pelvis is the most important part of the birth canal; the speed and smoothness of childbirth are closely related to the size and shape of the pelvis. Deformed pelvis can cause dystocia. Primigravidas and pregnant women with a history of dystocia should routinely measure and check the pelvis during the first prenatal examination. The pelvic measuring instrument currently used has a single function and can only measure the inner diameter of the pelvis unilaterally. Or outer diameter, in order to solve the above problems, a new technical solution is provided. Contents of the invention
