3D printing customized guide plate for hysteromyoma stripping operation and use method of 3D printing customized guide plate

Abstract

The invention discloses a 3D printing customized guide plate for hysteromyoma stripping operation and a use method thereof.The guide plate for hysteromyoma stripping operation comprises a bottom plate, the bottom plate is printed based on a uterus model, and the bottom plate is attached to body tissue of a patient; a positioning hole is formed in the bottom plate, and the attaching surface of the bottom plate is over against the uterus direction of a patient in an overlook manner; the use method comprises the following steps: carrying out three-dimensional reconstruction according to pelvic imaging data of a patient with multiple hysteromyoma before an operation, designing the guide plate on this basis, preparing by using a 3D printing technology, after the guide plate is embedded during the operation, positioning a target myoma by a guide needle with a positioning wire through a positioning hole, taking out the guide plate and the guide needle after positioning, and carrying out three-dimensional reconstruction according to the pelvic imaging data of the patient with multiple hysteromyoma. The target myoma is detected through the positioning wire, and the positioning wire is taken out while the myoma is stripped. The 3D printing customized guide plate for the hysteromyoma stripping operation and the use method thereof aim at improving the operation precision of an operator, reducing womb wounds, shortening the operation time and reducing the postoperative residual rate and the recurrence rate.

Description

Technical field [0001] The present invention involves the field of gynecological related technology, and is specifically printed with 3D printed customized uterine fibroids to strip surgery board and its usage. Background technique [0002] As the most common benign tumor for women's reproductive systems, uterine fibroids are composed of smooth muscles and connective tissues of the lesions. Affected by estrogen secretion, the incidence of women in the childbearing age is 20%-40%; [0003] Under the category of uterine fibroids, the submucosal fibroids will reduce the pregnancy rate of pregnant women; fibroids in the muscle wall will increase the abortion rate during pregnancy, and reduce the success rate of external insemination (IVF). Even if the fibroids do not affect the shape of the uterine cavity, There are two or more fibroids or fibroids with a diameter of more than 3cm. Women's IVF pregnancy rate and survival rate will also be significantly reduced; [0004] For patients ...

AI Technical Summary

Problems solved by technology

The suture of the wound after excision of type Ⅲ-Ⅴ intramural myoma is a difficult point in laparoscopic myomectomy. Poor suture will lead to hematoma and poor healing of uterine incision, which may lead to uterine rupture during postoperative pregnancy, endangering The life of the patient is safe; in addition, after multiple fibroids are removed in sequence, the anatomical shape of the uterus will change significantly, making it more difficult to locate the fibroids that were removed later in the sequence;
