Description

Guiding and measuring instrument device for gynecological operation

[ field of technology ]

The utility model relates to the technical field of medical instruments, in particular to a guiding and measuring instrument device for gynecological operation.

[ background Art ]

In real life, many middle-aged and elderly women and some postpartum mothers can suffer from the uncontrolled embarrassment and pain of pelvic organ prolapse, along with the gradual aging of population in China, the incidence rate of the diseases is gradually increased, the physical and mental health and the life quality of the women are seriously affected, in order to solve the problems, doctors usually perform special operations such as pelvic floor reconstruction, genital tract plastic and the like, the pelvic structure reconstruction is carried out, the anterior and posterior walls of vaginal distension are repaired simultaneously through hanging straps, meshes and suture, the normal position of the pelvic structure is recovered, and the uterus can be resected or reserved as appropriate. The operation wound is small, the postoperative recovery is fast, the pelvic floor structure of the patient is recovered to a great extent, and the life quality of the patient is improved. There are also some patients with non-vaginal deformities in the genital tract who require colpitis. However, in such procedures, it is desirable to suspend the vaginal vault/uterus with the aid of an instrument to facilitate the patient's post-operative maintenance of the normal vagina, as well as to provide positioning of the suspension site.

However, currently, the operation equipment commonly used in laparoscopic uterine operation is a uterine manipulator, which is an instrument used for hysterectomy or sub-total incision operation, and can be matched to position uterus in laparoscopic hysterectomy, laparoscopic tubal staining and liquid-passing examination, and various laparoscopic operation processes. However, the uterine lifting device is basically used for positioning or lifting the uterus, in the operations such as pelvic floor reconstruction, genital tract plastic and the like, a doctor also needs to lift the vaginal top/uterus to a certain position for operation, the traditional uterine lifting device cannot be suitable for operation, the condition of overhigh or overlow suspension is easy to occur in blind insertion, the organ can be damaged due to overhigh suspension, the long-term lower abdomen discomfort of a patient is caused after operation, the operation effect is influenced even the sexual life is influenced, and the like.

Chinese patent application: CN105310751a discloses a uterine lifting device capable of being positioned accurately, comprising a uterine lifting cup, a hollow operating rod connected with the uterine lifting cup and a guide rod arranged in the cavity of the operating rod and capable of extending out of the uterine lifting cup, wherein the uterine lifting cup consists of an upper part and a lower part, the lower part is fixedly connected with the operating rod, a plurality of ring grooves are arranged on the lower part along the axial interval of the peripheral wall of the lower part, and the upper part is a plurality of blades fixedly connected with the lower part and distributed along the circumferential interval. According to the cervical cancer lesion excision device, the uterine lifting cup is provided with the plurality of grooves, and when a cervical cancer lesion excision operation is performed, a doctor can determine the vagina excision length according to the positions of the corresponding grooves, so that the lesion can be accurately excised; the utility model is also provided with two scales on the control rod, wherein one scale can judge the entering depth of the control rod, and the other scale can judge the length of the guide rod extending into the uterine cavity; therefore, the utility model can accurately position by using the uterine lifting cup, the operating lever and the guide lever. Although the device is provided with the scale marks which can be positioned, the length from the fornix to the vaginal opening cannot be accurately judged and controlled by the two scale marks, positioning in operations such as pelvic floor reconstruction and genital tract plastic cannot be realized, the vaginal top or uterus can be lifted by suspending, when the uterus is resected, the vaginal top is lifted to suspend and maintain normal vagina, although the uterus lifting cup in the uterus lifting device can be clamped into the fornix to lift the uterus, but the vaginal top cannot be lifted to suture after the uterus is resected, the device is similar to the device in structure, but cannot be used in operations in the field to make the same effect.

In view of the foregoing, there is a need for a guiding and measuring device for gynecological operation, which not only is equipped with uterine lifting cups of different types to accommodate patients with different cervical sizes, so that the patients can completely wrap the fornix, but also is equipped with graduation marks to determine the accurate length of the whole vagina, so as to position and suture the whole vagina, and is additionally equipped with a vaginal top column to suspend the vaginal top, so that the guiding and measuring device is suitable for non-uterine patients, and maintains the normal genital tract of the patients.
