Description
Technical Field
The utility model relates to a medical consumptive material technical field especially relates to a suspender seam needle that is used for cervical cerclage under pregnant back laparoscopic.
Background
The cervical cerclage during pregnancy aims to prevent recurrent late abortion or premature birth caused by cervical insufficiency, and at present, the operation modes of cervical cerclage are divided into a transvaginal modified McDonalds operation mode, a Shirodkar operation mode and a transvaginal cerclage operation mode, wherein the transvaginal cerclage operation mode comprises an open mode and a laparoscopic operation mode. The vaginal cerclage is applied to the middle pregnancy, and is characterized in that no tissue needs to be cut, and only a suture is passed into and out of the wall of a vaginal fornix and surrounds the whole cervix so as to complete cerclage and prevent the cervix from expanding along with the increase of gestational months. The defects are that the cerclage position is low, cervical funnel-shaped changes still exist after most patients operate, meanwhile, the probability of late abortion, premature birth and cervical laceration of the patients is high, and only part of the patients can continuously perform pregnancy until delivery in term. The abdominal ligation is suitable for pre-pregnancy and early pregnancy, and is characterized by mainly comprising: firstly, the operation position is relatively higher and is closer to the isthmus of the uterus, so that the anatomy of the cervix uteri after the operation is closer to that of a normal pregnant woman, and the success rate of the gestation in the full term after the operation is improved; and secondly, cervical cerclage under the laparoscope is a minimally invasive operation, has smaller influence on the internal environment of the pregnant uterus and the pelvic cavity, can accurately judge the position of the needle passing in and out during cerclage, achieves cerclage of the isthmus of the uterus, reduces the damage probability to uterine blood vessels, and ensures that pregnancy is smoothly performed to the maximum extent. Because the cervical cerclage operation through the laparoscope is generally recommended to be carried out in the early pregnancy and in the stable pregnancy state, specifically 8-10 weeks of pregnancy, and no more than 12 weeks of pregnancy at the latest, the cervix of a patient in the period is wide, varicose, rich in blood supply and soft, special attention needs to be paid to protecting the uterine artery and vein blood vessels at the position of the uterine isthmus when carrying out cerclage on the uterine isthmus under the laparoscope, so that the smooth pregnancy is ensured, and meanwhile, other organs in the abdominal cavity are prevented from being damaged. This puts high demands on the needle body of the suture, and the proper needle inserting position and needle moving direction are also the key points for the success of the uterine isthmus cerclage under the laparoscope.
At present, MERSILENE suture lines for surgery are usually selected clinically, the length of the suture line is 40cm, the width of the suture line is 6mm, two ends of the suture line are connected with suture needles, the length of each suture needle is 4.9cm, each suture needle is arranged in a circular arc shape, a needle body is longer, when a laparoscope descends to a uterine isthmus for circular ligation, the suture needles arranged in the circular arc shape enable the needle inserting angle to be difficult to grasp, uterine artery and vein blood vessels are easy to be damaged when the needle is withdrawn, in clinic, an operator often manually adjusts the radian of the suture needles, but the mode is not in line with hospital feeling requirements, on the other hand, the radian of the end portions of the adjusted suture needles is uneven, and the operator can experience a certain test in each operation. In addition, when an operator manually adjusts the suture needle, the needle point of the suture needle can stab the hand of the operator, which causes the pollution of the suture needle; improper needle adjustment methods can also cause the needle body to break. This on the one hand causes harm to the body of the operator and on the other hand also increases the medical consumables.
Chinese patent No. 201720945786.3 discloses "a surgical suture for cervical cerclage under laparoscope", in which the suture needles at both ends of the suture are straight, but through repeated clinical practice, we find that the straight suture needle is more suitable for cervical cerclage before pregnancy, and due to the change of the cervix during pregnancy, the suture needle is not beneficial for the operator to grasp the position of needle insertion and the direction of needle insertion, so that the possibility of blood vessel injury and injury of adjacent organs such as intestinal canal of the patient is higher. In addition, the two-end suture needle is generally designed in such a way that the two uterine isthmus are inserted from front to back and knotted at the back of the uterus, and because the uterine body is enlarged in the pregnancy period and the operable space in the pelvic cavity is limited, the knotted at the back of the uterus is bound to cause the limited operation space, so that the uterus needs to be lifted repeatedly, and the corresponding operation difficulty, threatened abortion or inevitable abortion, and the risks of injury of adjacent organs such as intestinal tracts and blood vessels are increased. When cervical cerclage is performed in pregnancy, the method which is often adopted is to open round ligaments on two sides of the uterus and get through the front and rear leaves of a wide ligament in the uterus, so that an angionic region of the uterine isthmus and an operation space required by an operation are exposed, a needle is inserted from front to back on the left side of the uterine isthmus, a needle is advanced from back to back on the right side of the uterine isthmus, a suture body is tightened and knotted in front of the uterine isthmus, during the operation, the uterine body is subjected to less touch and touch for adjusting the required position of the uterine body, and the risk of threatened abortion and unavoidable abortion after the operation is reduced.
