Description

A manufacturing system and method of customized pessary using 3D printer, and patient-customized pessary manufactured thereby}

The present invention relates to a manufacturing system and manufacturing method for a customized pessary using a 3D printer, and to a patient-tailored pessary manufactured thereby. More specifically, it relates to determining the presence and degree of uterine prolapse and determining the shape of the patient's pelvis, vagina, and uterus. It relates to a manufacturing system and manufacturing method for a customized pessary using a 3D printer, and a patient-tailored pessary manufactured thereby.

Uterine prolapse, also known as uterine ptosis, is a disease that occurs mainly as the muscles, fascia, and ligaments that support internal organs stretch with age, causing tissue tension to decrease and relax.

When uterine prolapse occurs, the uterus prolapses out through the vagina, making it difficult to walk, and pressing on the bladder, making it difficult to urinate frequently or urinate. In severe cases, it is a disease that requires surgery or other treatment because it affects kidney function. Severe uterine prolapse is treated through surgery, but for patients whose general condition is so bad that surgery is difficult or who refuses surgery, a pessary is used.

However, just because the uterus is prolapsed, it does not mean that it will come out of the body. In most cases, it descends to the area near the back half of the vagina and may come out when pulled. It is usually caused by pregnancy, childbirth, or dystocia.

In mild cases, uterine prolapse can be treated with exercise therapy and medication, but in severe cases, surgery or devices must be used to fix the sagging uterus.

Surgical treatments have been studied to reduce the risk of recurrence of prolapse through complex and sophisticated abdominal, vaginal, and laparoscopic procedures such as abdominosacral colpopexy, dura-sacral ligament fixation, and laparoscopic sacral colpopexy, but these procedures require highly specialized surgical procedures. Not only does it require knowledge, but it is also known that the failure rate of surgery is relatively high.

Therefore, the treatment of patients with uterine prolapse using instruments is widely used, except for very severe patients.

There are various types of pessaries related to this, but only one type of ring pessary is imported and used in Korea.

However, because a woman's pelvis, vagina, uterus, etc. have different shapes and sizes for each person, if only one type of ring pessary imported into Korea is used, it may be difficult to see the effect of the treatment because the ring pessary does not fit the person's body. There was a problem with side effects occurring on the body.
