Description

Self-adaptive vaginal dilation irrigator Technical Field The invention relates to the technical field of medical appliances, in particular to a self-adaptive vaginal dilation irrigator. Background Cervical cancer is one of the common malignant tumors of female reproductive systems, and various local complications are often accompanied in the treatment process, so that the treatment effect, the quality of life and the survival prognosis of patients are seriously affected, wherein abnormal accumulation of vaginal and uterine cavity secretions and narrow adhesion of the vagina and cervical orifice are key problems to be solved in clinical urgent need. In clinical diagnosis and treatment of cervical cancer patients, uterine cavity flushing is an important local treatment measure. Because of the invasiveness of cervical cancer focus itself and the stimulation to local tissues in the treatment process, a great deal of secretion is often generated in the vagina and the uterine cavity of a patient, if the secretion can not be cleared timely and thoroughly, the secretion can accumulate in the vagina and the uterine cavity for a long time, so that local inflammatory reaction can be aggravated, and the secretion can become a warm bed for bacteria breeding, thereby inducing infection and affecting the treatment process, therefore, the vagina and the uterine cavity of the patient need to be regularly and thoroughly flushed locally to clear the secretion, keep local clean, and create a good local environment for treatment. Meanwhile, vaginal dilation is an indispensable adjuvant therapy for cervical cancer patients receiving radiotherapy. In the radiotherapy process of cervical cancer, radioactive rays can cause certain damage to vagina and cervical tissues, so that local tissues are subjected to pathological changes such as congestion, edema and fibrosis, if the vaginal dilation intervention is not performed in time, the damaged tissues can gradually shrink and adhere after the radiotherapy is finished, and then the vagina and cervical stenosis is caused, and severe adhesion can be formed when severe. Once severe adhesion occurs, secretion generated in the uterine cavity cannot be normally discharged, long-term accumulation in the uterine cavity can cause uterine cavity hydrops, further secondary bacterial infection can cause severe complications such as bacteremia under severe conditions, the life quality of a patient can be obviously reduced, and adverse effects can be caused on the survival time of the patient, so that the vaginal dilation is regularly performed during and after radiotherapy, and the method is a key means for preventing the adhesion of the stenosis of the vagina and cervical orifice. However, related instruments used in clinic at present have the common defect of single function, namely, the related instruments only have the function of vaginal dilation, can only realize mechanical dilation of the vagina to prevent adhesion, can not effectively wash secretions in the vagina and the uterine cavity, and cannot solve the problem of secretion accumulation, or only have the function of uterine cavity washing, can only clear the secretions, can not realize vaginal dilation, and can not prevent narrow adhesion of the vagina and the cervical orifice after radiotherapy, for example, reference 1. Reference 1 chinese patent document publication No. CN 120000390A. Reference 1 describes a uterine cavity support for preventing uterine cavity adhesion, which comprises a push rod, a support body, an air bag and a support body, wherein one section of the push rod is connected with a fixed rod in a sliding manner, the support body is arranged on the fixed rod, the push rod is used for inflating the air bag, and the air bag enters the uterine cavity through the fixed rod and drives the support body to be unfolded after being inflated. When the uterine cavity is accessed, the air bag and the support body are wrapped by the push rod, the uterine neck opening can be accessed smoothly, discomfort to a patient can not be caused due to the fact that the area of the support body is too large, after the air bag is inflated in the uterine cavity, the unfolding speed of the support body can be reduced, and the injury to the uterine cavity is reduced. Based on the clinical demands and the defects of the prior art, a special device with multiple functions is urgently needed in clinic at present, and the device can not only effectively flush the vagina and the uterine cavity and thoroughly remove the secretion accumulated locally, but also simultaneously complete the intravaginal dilation operation, and effectively prevent the stenosis and adhesion of the vagina and the cervical orifice after radiotherapy, thereby reducing the occurrence of complications and improving the life quality of patients. Disclosure of Invention The invention aims to solve the technical problems in the prior art and provides a self-adaptive vaginal dilatio
