Description

Novel fornix cup for prolapse of vaginal fornix after total hysterectomy
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a novel fornix cup that is used for full hysterectomy postoperative vaginal fornix to prolapse.
Background
At present, the incidence of prolapse of the vaginal stump after total hysterectomy is about 5 percent. The prolapse after the total hysterectomy comprises prolapse of the front and back walls of the vagina and prolapse of the fornix of the vagina, and the colposacral fixation under a laparoscope is one of the internationally recognized gold standard operation formulas at present. In a laparoscopic sacrum fixation operation of a vagina, a bladder vaginal gap and a rectovaginal gap under a laparoscope need to be separated, but the separation of the bladder and the vaginal gap is difficult due to adhesion of the bladder and the front wall of the vagina or adhesion of the rectum and the back wall of the vagina caused by the previous operation of a patient, especially, the separation under the laparoscope has no hand feeling, the bladder and/or the rectum are easily damaged in the separation process, and the damage rate is about 3-10%. Traditional laparoscopic colposacral fixation can only solve prolapse of the middle pelvic cavity, i.e., the fornix and the upper vaginal segment. The existing improved laparoscope colposacral fixation improves the position for placing a patch, better supports the lower vaginal segment, and is suitable for patients with anterior and posterior pelvic prolapse by using the laparoscope colposacral fixation. In order to solve the surgical problem of bladder and/or rectum injury during the separation process, a fornix cup needs to be designed.
At present, some fornix cups are simple in structural design, the appearance of the fornix cups is similar to that of a widely practical uterine elevator at present, the cup mouths of the fornix cups are cylindrical, the contact area is large, operative fields can be fully exposed, models with different sizes can be selected according to the width of the vagina, the risk of damaging the vaginal stump and the bladder is increased due to the fact that the contact surface is too large, and the possibility of directly breaking the stump causes incision cracking, rectal injury and bladder injury. Different types of fornix cups are selected according to the width of the vagina, so that the vaginal dilator is not suitable for all patients, and the size of the vaginal dilator is not matched with the size of the vagina of the patient and cannot be completely attached to the vaginal wall. Even the smallest fornix cup can not be placed in a patient with narrow vaginal entrance after menopause, thus seriously influencing the feasibility and the safety of the laparoscopic sacrum fixation of the patient with vaginal fornix prolapse after the total hysterectomy. At present, the commonly used uterine elevator and fornix cup are made of hard materials, are mostly made of plastic cups and are easy to damage the vaginal crinkles.
The examination of chinese patent document ZL201822044661.0, a utility model patent with an granted publication date of 2019.10.11, discloses: by arranging the cup body into a deformable structure, the fornix cups with different sizes can be realized during inflation or deflation so as to ensure that the fornix cups are in a smaller size before being placed and in a size tightly matched with the vaginal wall after being placed and inflated, so that the degree of fit between the fornix cups and the vaginal wall is improved, and the feasibility and the safety of the operation are ensured; through setting up the breach, can guarantee that the cup can satisfy the structure of closely laminating the vaginal wall after aerifing, this disposable inflatable fornix cup is compact structure, can effectively solve the problem such as fornix cup size not harmonious, with vaginal wall coincidence degree not good, but its gasbag inflation pipe connects in the cup body, is not suitable for the long and dark patient of vagina, probably puts into the vagina with inflation pipe together because of the too dark overlength of vagina, influences the use. The above patent documents are limited to disposable use, and the manufacturing cost thereof is high.
Other disposable inflatable fornix cups are only used for assisting the resection of the whole uterus in the application scene, the cup mouths of the disposable fornix cups are saddle-shaped like a common uterine lifting cup, the upper lip and the lower lip are asymmetrical and sharp, the vaginal stumps are easy to cut, and the asymmetrical upper lip and the lower lip cause the length of a bladder gap separating the vagina in the operation to be different from the length of the vagina rectum and are not easy to perform up-and-down involution.
How to solve the above problems is a technical problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a be suitable for supplementary vagina fornix cup of sacrum fixation under peritoneoscope of complete hysterectomy postoperative, avoid because of fornix cup size degree of agreeing with not good, the too big security and the success rate that influence the operation process of rim of a cup contact surface.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a novel fornix cup for prolapsing of vaginal fornix after total hysterectomy comprises a guide rod and a fornix cup; the vault cup is connected with the guide rod through a connecting body, a handle is installed on one side, far away from the connecting body, of the guide rod, and a cup body size adjusting mechanism used for adjusting the outer diameter of the cup body is arranged in the vault cup.
Furthermore, the cup body size adjusting mechanism comprises a plurality of cup body air bags arranged in the fornix cup and an inflatable air bag used for inflating and deflating each cup body air bag, and the inflatable air bag is positioned outside the fornix cup.
Furthermore, the cup body air bags are uniformly distributed in the fornix cup, and the adjacent cup body air bags are connected and communicated through an air bag connecting partition plate; the inflatable air bag is communicated and installed at one end, far away from the fornix cup, of the guide rod, the guide rod is a hollow guide rod, and the guide rod extends into the fornix cup and is communicated with at least one air bag of the cup body through a pipeline.
Furthermore, the cup body air bag and the air bag connecting partition plate are distributed along the long axis direction of the fornix cup, and the lengths of the cup body air bag and the air bag connecting partition plate are both smaller than that of the fornix cup.
Furthermore, the connecting body is funnel-shaped, one end of the opening of the connecting body is fixedly connected with the fornix cup, a connecting thread used for being connected with the guide rod is arranged at the base end of the connecting body, and the guide rod is detachably connected with the connecting body through the connecting thread.
Furthermore, the air bag connecting partition plate and the connecting body are both made of hard materials.
Furthermore, one end, far away from the connecting body, of the fornix cup is a fornix cup opening, and a circle of flexible and deformable air bag is arranged on the edge of the fornix cup opening.
