Development Of Minimally Invasive Surgical Abortion System Based On Visualization

At present, abortion is is the expulsion of an embryo or fetus before approximately the 22nd week of gestation. Used as a contraceptive failure and remedial measures. According to the World Health Organization estimates of the reproductive health indicators, there are about four hundred million people around the world without the guidance of contraception, approximately 50 million women accept abortion each year. There are four domestic passenger Methods:mechanical abortion, vacuum abortion and the newly developed painless and visual flow. Each approach has many drawbacks, easily lead to various complications of surgical abortion and gynecological diseases. The purpose of abortion is termination of early pregnancy, in fact, you can just clear the gestational sac, decidual tissue will be off on their own. However, the traditional induced abortion can not see the status of the uterus, a doctor with experience is completely blind scraping of the uterine cavity, in addition to removal of the entire gestational sac outside the uterine lining also caused extensive trauma, may lead to uterine perforation, incomplete abortion, missed absorption, bleeding, infection and other complications can also result in intrauterine adhesions, menstrual disorders and so on. To facilitate the surgical procedure now, you need to expand the cervix, causing mechanical cervical lacerations and severe painThe abortion of this study is that the benefits of visualization of the doctor before surgery visual device inserted into the uterine cavity, can be directly observed in the uterine cavity on the screen within the state, determine the gestational sac position, fixed on the pregnancy sac to suction, on gestational sac outside the uterus lining does not produce damage, the doctor looked at the screen surgery, the accuracy of the natural high, and greatly reduce the trauma, truly minimally invasive Solved the problem of the subject is that can clearly see the uterine cavity during the operation and avoid blind scraping. Including micro-electronic endoscope design, and How to combine the electronic endoscope and the electric vacuum aspiration, both Both the surgery visual image is clear in the uterine cavity, the visual devices are not required to extend the cervix to avoid injury. With great risk, from a medical point of view is prohibited, so the media can not be used for uterine distention abortion, must study the new technology of non-uterine distention media.This paper focuses on two aspects, the first is the detailed visual endoscopic suction tube design and design of a number of issues to be addressed to compare several designs in detail to illustrate the design ideas and design process, pop-up video to promote the vane suction tube pulled out of the camera tube liter internal volume control problems to solve to suction, elastic inflatable balloon into the uterus before the contraction is not inflatable, inflatable, including endoscopic examination for the purpose to achieve uterine enlargement does not cause an overflow into the other gas outside the cavity to form gas embolism. Improved pop-up visual suction tube with integrated packages designed to solve a visual pop-up problem when the edge is not smooth. Professional design details are explained in a clear structure and the installation of cameras was discussed for the traditional advantages and attractive effects, the design show. In this paper the main features of the final design is the use of combo structure, without changing the basis of the existing surgical techniques to increase the visual function, to avoid scraping the blind, to achieve the goal of minimally invasive surgery. This structure not only visual devices can be visualized as an independent gynecological examination device, can partially replace hysteroscopy, colposcopy, and other special video equipment, inspection of other uterine disease; while negative pressure device is by curettage into the hollow handle visual equipment, and conducting inspection without moving the test equipment to control the flow into the suction curettage procedure, which saves time and relieve the pain involved in the second device, further reducing the damage to the cervical canal.On the other hand, this paper describes the development of imaging workstation that explain its video capture, image processing, system settings and other functions in detail. The workstation developed by Visual Studio 2008, using C# and C++ language as a system development language, which is mainly mixed technology. The video workstation with graphical user interface is intuitionistic. For the function of system directly action by the shortcut button, it can be more easily for doctor to use and greatly improving clinical efficiency. That could be more clearly and convenient to suck out a visual fertilized egg. The real-time display clear images make teaching, observation and consultation more convenience. According to different video signals and video formats, it would be free to select that is needed. With the visual image processing functions, user can process the results in time and the system program would automatically save the results of selection. Furthermore, user can mark text in the image by the function of image annotation. Software testing is at the end of the development.
