Description
Technical field
This utility model belongs to technical field of medical instruments, particularly a kind of implantable equipment for using in amputation of cervix.
Background technology
At present, cervical cancer is still the underlying cause of death of global patients with gynecologic malignancies, and on the one hand, cervical carcinoma screening makes the ratio of making a definite diagnosis of early cervical carcinoma rise; On the other hand, along with the cervical cancer pathogenesis age presents rejuvenation trend and the postponement of modern society's childbearing age, in human invasive cervix neoplasms patient, the Proportion of patients of not giving birth to rises year by year.The traditional treatment mode of human invasive cervix neoplasms is excision uterus and regional lymph nodes, or kills primary tumor and lymphatic drainage district tumor by radiotherapy, but operation or radiotherapy all will cause patient to lose reproductive function while treatment tumor.Above factor makes the reproductive function retaining patient more and more important in the treatment of cervical cancer.Charles Robert Richet Daniel Dargent has carried out Radical trachelectomy (radical trachelectomy, RT) first in 1987.The excision extension changing art formula is similar to classical female radical hysterectomy, and only the cervix uteri of excision pathological changes, coincide isthmus uteri and vagina upper end, makes patient remain reproductive function while healing tumor.Current RT operation mainly contains female Radical trachelectomy (vaginal radical trachelectomy, VRT) and abdomen formula Radical trachelectomy (abdominal radical trachelectomy, ART) two kinds.
The narrow adhesion of cervix uteri pore is post-operative complication the most typical and common after abdomen formula Radical trachelectomy, not only can affect the normal morphology and function in uterus and then affect human endocrine, and can cause infertile, this is obviously that perform the operation with the ART original intention that retains patient's reproductive function is contrary.The patient accepting the narrow adhesion of ART postoperative generation cervix uteri pore often has to again to accept cervical canal bore expansion operation more than once, this undoubtedly to the health of sufferer, at heart and economy bear and all create new pressure.Therefore, we are attempting to find the method that can prevent the narrow adhesion of postoperative cervix uteri pore in ART operation always.
Utility model content
An object of the present utility model is to provide a kind of cervix uteri pore anti device, to be applicable in amputation of cervix process in patients with implantation body.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of cervix uteri pore anti device, comprise T-shaped frame member and tailfiber, T-shaped frame member comprises transverse arm and trailing arm, transverse arm is by elastic bending deformation can occur, trailing arm is vertically connected at the middle part of transverse arm, and trailing arm one end away from transverse arm is provided with perforation, and tailfiber is bored a hole and fixed.
The cervix uteri pore anti device that embodiment of the present utility model provides, for in amputation of cervix process, before sewing up stump palace body and vagina, after implementer utilizes operating theater instruments to adopt operating theater instruments firmly to clamp to the trailing arm of T-shaped frame member and transverse arm, under the state that transverse arm is in elastic bending deformation, it is deeply placed in patient uterine; Then operating theater instruments removes clamping, and the original state before the transverse arm recovery elastic deformation of T-shaped frame member, namely trails and support and be fixed on bottom body of uterus.Perforation is provided with away from one end of transverse arm at the trailing arm of T-shaped frame member, be installed with tailfiber in perforation and fix, this cervix uteri pore anti device patients with implantation intrauterine, after patient sews up stump palace body and vagina, a part for tailfiber will be stayed external: on the one hand, tailfiber is together with the trailing arm of T-shaped support, and the cervix uteri pore caused the adhesion of postoperative neck tube mucosa is narrow preventive effect; On the other hand, the patient accepting amputation of cervix, after adhesion acute stage in the past, by this tailfiber of tractive, when being taken out in patient body by antiseized connected device without the need to when anesthesia, avoids the generation of second operation.
Relative to prior art, cervix uteri pore anti device of the present utility model effectively prevent the complication that the narrow adhesion of cervix uteri pore occurs patient after surgery, remain the reproductive function of patient, raising cervical cancer patient postoperative quality of life and mental emotion state are all had very great help.
Further, in the cervix uteri pore anti device that embodiment of the present utility model provides, the trailing arm of T-shaped frame member away from transverse arm one end overstriking and form chondritic, perforation runs through and is arranged in this chondritic.This kind of overstriking also forms the trailing arm end of chondritic, the firm power of trailing arm end can be increased, reduce thus and take out in the process of this Anti-adhering device at tractive tailfiber, the perforation being located at the trailing arm end of T-shaped frame member is broken because of insufficient strength and then is caused tailfiber to come off and situation that Anti-adhering device is still detained in body occurs.
Further, in the cervix uteri pore anti device that embodiment of the present utility model provides, tailfiber is wound around N circle in perforation, by increasing the lifting surface area between tailfiber and perforation, reach reduce in tractive tailfiber process, tailfiber perforation in fracture and occur tailfiber come off and Anti-adhering device be still detained in body situation generation.
