Features:

■This simulation model is made of high-quality materials, anatomical position is accurate, the skin is soft and elastic, the feel is realistic, the lesion tissue is real.

■ in the cervix vaginal mucosal junction below the 1cm of the posterior fornix in the center, and the cervical canal parallel to the direction of the puncture (with a 7-gauge puncture needle), there will be a reddish liquid pumped out. The quality of the puncture procedure is shown to be up to standard.
