Auxiliary vagina dome indicator for gynecological operation

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and discloses an auxiliary vaginal dome indicator for gynecological surgery, which comprises an operating rod, an air bag support, a first air bag, a second air bag, a movable ring, and a first breather pipe and a second breather pipe for supplying air to the first air bag and the second air bag respectively, the air bag support is fixed to the top of the operating rod. The first air bag is arranged in the air bag support, an air inlet of the first air bag is connected with the first breather pipe, the second air bag sleeves the outer side of the operating rod, and an air inlet of the second air bag is communicated with the second breather pipe; the movable ring is located below the second air bag and movably connected to the outer side of the operating rod, and the first breather pipe and the second breather pipe are provided with a first air valve and a second air valve respectively and connected with an air source. The vaginal dilator is simple in structure and reasonable in design, is particularly suitable for gynecologic transabdominal hysterectomy, can firmly fix vaginal dilator, plays a role in positioning and indicating, and avoids surgical risks caused by using methylene blue and gauze strips in the prior art.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an auxiliary vaginal vault indicator used in gynecological operations, in particular to an auxiliary vaginal vault indicator in the process of transabdominal hysterectomy. Background technique [0002] At present, during gynecological surgery, methylene blue needs to be sprayed on the external cervical orifice and the vaginal fornix should be positioned with gauze padding in order to reduce the contamination of the vaginal wall caused by the prolapse of the cervical orifice after the lesion is squeezed. open the vagina, spray methylene blue to the vaginal fornix, fill the gauze strip into the vagina through the middle channel of the speculum, and then withdraw the speculum. However, this operation has the following disadvantages: (1) Some patients have a long vagina and a short speculum, or the influence of the primary disease (such as a huge uterine fibroids or a pelvic ma...

AI Technical Summary

Problems solved by technology

However, this operation has the following disadvantages: (1) Some patients have a long vagina and a short speculum, or the influence of the primary disease (such as a huge uterine fibroid or a pelvic mass, which causes the cervix to be compressed and shifted), Insufficient exposure of the cervix, inadequate spraying of methylene blue, inadequate packing of gauze strips, or loosening of gauze strips during the operation cannot serve as an indication for surgery

(2) During the withdrawal of the speculum, the vaginal gauze that was tightly packed in the fornix may come out, making it difficult for the surgeon to accurately judge the position of the vaginal fornix during the operation

For doctors with insufficient surgical experience, there are hidden dangers in surgical safety

(3) Due to the material and production of gauze strips, there are often pollutants such as thread ends and fluff, which can easily cause wound non-healing and infection

At the same time, gauze strips also have a safety risk of unqualified sterilization

(4) For patients with endometrial cancer involving the cervix and cervical cancer, the lesion may protrude from the cervix and contaminate the vaginal wall after being squeezed, and the gauze strip is loose, which cannot effectively prevent the metastasis of the auxiliary cancer Effect
