Description

Technical Field

[0001] The utility model relates to the field of uterine diverticulum repair, in particular to a uterine diverticulum stapling manipulator. Background Art

[0002] Uterine diverticulum (PCSD), also known as uterine incision diverticulum, cesarean section uterine incision diverticulum, cesarean section uterine scar defect), is formed due to poor healing of the previous cesarean section uterine incision. The most common clinical symptom of PCSD is abnormal uterine bleeding, which can be manifested clinically as: prolonged menstruation, intermenstrual bleeding, vaginal bleeding, bleeding after intercourse, etc. It can also manifest as clinical symptoms such as secondary infertility, dysmenorrhea and chronic pelvic pain.

[0003] The narrow structure of the vagina and uterus makes surgical suture difficult. The surgical treatment of uterine diverticulum is usually to remove the diverticulum scar tissue and then consider the operation as completed. After the operation, the patient needs to take medication to recover on his own. However, since the diverticulum is not closed during the operation, the patient sometimes has diverticulum scars again after the operation, which requires multiple uterine diverticulum removals. Therefore, there is an urgent need for a device that can directly close the uterine diverticulum after removing the diverticulum scar tissue.

[0004] The utility model patent with patent number CN213158848U provides a compression device for uterine scar pregnancy and uterine diverticulum surgery, which compresses the upper part of the uterus by injecting liquid into the compression tube to form a bulge, thereby achieving closure during surgery. However, this technology cannot guarantee that the diverticulum will remain closed after surgery, and it cannot guarantee that new diverticula and scars will not grow again after surgery if there is a residual uterine cavity hole after the diverticulum is removed.
