Description
Technical Field
The invention relates to a vaginal suture auxiliary mirror.
Background
Vaginal suture surgery is one of the common operations in obstetrics and gynecology, which enables suture repair of vaginal lacerations, cuts or perforations caused during childbirth or vagina contracting surgery. However, due to the particularity and complexity of the internal structure of the vagina, the operation is difficult and requires a high level and experience for the doctor.
At present, the main difficulties of the vaginal suture operation are: firstly, the position of the vaginal wound is difficult to observe, and in the prior art, the position of the vaginal wound is generally determined by a doctor in a way that the doctor touches the rectal mucosa by fingers, so that the judgment needs to be carried out by depending on the experience of the doctor, and the requirement on the level of the doctor is high; secondly, the wound position is difficult to determine in the vagina, and the vagina suture operation is performed in the vagina, and the vagina wound position is required to be marked after being determined in the rectum, so that a main surgeon can suture the wound in the vagina, and in the prior art, the wound position is assisted to be marked by an assistant doctor in the rectum in a light irradiation mode, so that the light irradiation is required to be kept stable in the repair process, and the operation is inconvenient; thirdly, the suture operation is difficult, and the loose and wrinkled inner wall of the vagina brings a lot of difficulties for the suture repair of wounds; fourth, observation of the postoperative effect is also relatively inconvenient.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the vaginal suture auxiliary mirror which is simple in structure, can be used for assisting the vaginal suture operation, enables the operation process to be simpler and more convenient, reduces the operation difficulty, and improves the operation efficiency and success rate.
In order to achieve the purpose, the invention provides a vaginal suture auxiliary mirror which comprises a base body, wherein an extension arm extending forwards is arranged at the front end of the base body, a probe slightly tilting upwards is arranged at the front end of the extension arm, an illumination element and a camera are arranged at the end part of the probe, a display screen matched with the camera for display is arranged at the rear end of the base body, a base is arranged at the lower end of the base body, two side wings capable of being opened upwards or closed downwards in a rotating mode are arranged at the positions, close to the two sides of the probe, of the extension arm, an operation knob is arranged on the base body and is in transmission connection with the two side wings, and the operation knob can control the two side wings to be opened or closed simultaneously when rotating.
The beneficial effect of adopting above-mentioned technical scheme is: during the use will prolong the probe of arm front end and stretch into to the rectum, because the tip of probe is provided with light irradiation component and camera, the doctor can inspect the rectum mucosa that is close to vagina inner wall department directly perceivedly through the display screen that the base member rear end set up, can conveniently, seek the wound position of finding the vagina fast. The probe which is slightly tilted upwards is convenient for the camera to align to the rectal mucosa close to the inner wall of the vagina, so that the doctor can conveniently check the rectal mucosa. In addition, the base is arranged at the lower end of the base body, the vaginal speculum is arranged on the table board through the base, the probe is always aligned to a wound, and the light beam of the illumination element can penetrate through the rectal mucosa to enter the vagina due to the fact that the rectal mucosa is thin, so that the vaginal wound can be marked, and a doctor can find the wound in the vagina conveniently. Because the extension arm is provided with two flanks and the base member is provided with the operation knob which can control the two flanks to open or close simultaneously at the position close to the two sides of the probe, a doctor can upwards rotate the two flanks to open and tighten the rectal mucosa after stretching into the rectum by rotating the operation knob, the doctor can repair the wound with the suture in the vagina conveniently, and the two flanks are controlled to downwards rotate to close after the operation is finished, so that the extension arm and the probe can be taken out from the rectum conveniently.
