Description
Technical Field
The invention relates to a medical correction and resetting tool, in particular to a Gong Nafan correction and resetting tool, and belongs to the technical field of medical appliances.
Background
The endometrium refers to the pathological changes of the bottom of the uterus sinking into the uterine cavity and even turning out from the cervix, which is a complication which is rare and serious in the childbirth period and mostly occurs in the third labor period, if the puerpera dies in 3-4 hours due to shock and hemorrhage, the endometrium is timely found and clearly diagnosed as the basis of treatment, and the endometrium patient often combines serious clinical manifestations of pain, hemorrhage, infection, shock and the like in the diagnosis and treatment process, so that the pain is actively relieved, and the bleeding, the infection and the shock are the preconditions of the treatment of the endometrium.
Factors causing the endometrium are difficult to separate from placenta caused by placenta implantation abnormality caused by multiple induced abortion or childbirth history, uterine operation history, pre-placenta, implanted placenta and the like besides congenital uterine dysplasia of the puerpera or excessive weakness of the puerpera, and the umbilical cord is easy to directly cause the endometrium when the umbilical cord is pulled to the uterus in the process of delivering the clinical fetus; in addition, in the clinical situation of the puerperal women with loose uterine walls and expanded uterine cervix, most of the endometrium is treated improperly (about 50%) due to the third labor, and the midwife pulls strongly the placenta umbilical cord attached to the uterine fundus, at this time, if the umbilical cord is tough and not broken from the placenta, the endometrium occurs when the loose uterine fundus is pressed with force.
The clinical treatment for endometrium is operated after the whole body condition of the patient is controlled, the treatment measures comprise the treatment measures for retaining uterus and resecting uterus, the former usually comprises transvaginal bare-handed reposition, transvaginal hydraulic reposition and transvaginal reposition under the guidance of medical imaging technology (such as B ultrasonic), the latter adopts the partial or total hysterectomy through abdomen or vagina, and the latter mainly adopts the measures according to the whole body condition of the patient, the time of endometrium, the infection degree, the fertility requirement, whether other reproductive system tumors are combined or not, and the like.
The main doctor usually needs to conduct operation with medical image guidance, touch and clinical experience, on the one hand, the operation needs to keep the manipulation soft under the condition of smaller space, and has higher requirements on the skill of doctors, on the other hand, in the process of uterine reposition, the uterine tissue which is everted outside the birth canal is pushed into the birth canal by palm lifting firstly, and then is pushed into the abdominal cavity by fist holding mode, but in the pushing process, not only the probability of infection is easy, but also the pain of the puerpera is increased by the small arm with the enlarged peripheral size, the fist surface cannot be in contact with the uterine tissue in a complete fit way, the hand usually moves in the abdominal cavity to ensure that the uterine inner wall is completely reset, and in particular, the puerpera inner wall is easily folded to cause friction to cause the inner wall to be attached to the inner wall to further cause the probability of infection before the uterine opening.
