Vaginal dilator for gynecological operation

Abstract

The invention relates to the field of medical instruments, and discloses a vaginal dilator for gynecological surgery. The vaginal dilator comprises a vaginal dilator body, wherein the vaginal dilator body comprises a lower support sheet, an upper support sheet arranged above the lower support sheet in a lifting manner, and a first driving mechanism for driving the upper support sheet to lift and lock relative to the lower support sheet; an image acquisition mechanism and an automatic sampling mechanism are detachably fixed to the end away from the vaginal orifice, of the lower supporting sheet, the image acquisition mechanism comprises a fixing block, a guide rail and a second driving mechanism arranged between the guide rail and the fixing block and used for driving the guide rail to ascend, descend and be locked, and a support provided with a colposcope and LED lamps is arranged above the guide rail in a guiding fit mode; and a third driving mechanism for driving the support to reciprocate in the axial direction of the guide rail is arranged between the support and the guide rail, and the image acquisition mechanism and the automatic sampling mechanism on the vaginal dilator are detachably arranged and can achieve peeping of the internal condition of the vagina and automatic sampling of the cervix uteri in the peeping state. The sampling accuracy is obviously improved, and the operation complexity is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a vaginal dilator for gynecological operations. Background technique [0002] At present, doctors mainly rely on vaginal dilators and colposcopes to examine gynecological patients. The vaginal dilators are used to dilate the vagina. Under the irradiation of external light sources, doctors can examine the cervix. The colposcope must be used with the help of vaginal dilators. The best method of use is to first open the vagina with a vaginal dilator, place the colposcope at a certain distance outside the vagina, and observe, photograph and collect images of the patient's vagina with the help of an external light source. The above-mentioned application of the colposcope has the following disadvantages. The doctor needs to hold the colposcope while observing the images fed back by the colposcope in the computer to find the lesions, which is inconvenient for the doctor to use and con...

Problems solved by technology

[0004] The above-mentioned invention applies the colposcope and LED lights to the vaginal dilator, and the patient’s cervical image can be directly received from the computer without the doctor holding the colposcope. However, the above-mentioned setting still has the following deficiencies in practical application: 1. The vaginal device is a disposable medical consumable, and the vaginal environment of the patient is different, and the pathogenic bacteria carried in it is unknown. If the above-mentioned vaginal dilator is a disposable product, the built-in electronic controller will be expensive, resulting in The significant increase in the cost of the entire vaginal dilator will significantly increase the cost of the patient, and the application prospect is not promising; 2. In the gynecological examination, it is necessary to collect samples. The existing operation is that the doctor directly holds the cotton swab and stretches it. Into the inside of the vaginal dilator without a colposcope, and take a sample by touching the cotton swab to the patient's cervix by feeling, which may lead to sampling deviations, that is, samples from the disease-causing area are not collected, which affects the follow-up treatment of the patient, and manual sampling is time-consuming It is laborious and increases the work of the doctor. Although the vaginal speculum of the above comparative literature can be sampled with the help of images, because the colposcope itself occupies the internal space of the vaginal speculum, it will increase the difficulty of manual sampling and will significantly prolong the time for a single patient. The treatment time of the patient is reduced, and the work efficiency of the doctor is reduced
