  • the invention relates to an intrauterine imaging device developed to provide a new approach to camera imaging from intrauterine imaging techniques.
  • the invention relates to an intrauterine imaging device that displays images taken from the uterine cavity by transferring the images taken from the uterine cavity to the screen taken by a wired camera, with a camera advanced from the cervix and a light source rod (hysteroscopy) developed in order to provide a new approach to the camera imaging technique, one of the intrauterine imaging techniques.
  • a light source rod hysteroscopy
  • hysteroscopy procedure is used to evaluate the inside of the uterus with the help of a camera in the diagnosis and treatment of gynecological diseases.
  • anesthesia application is needed especially in therapeutic hysteroscopy procedures. Although rare, this procedure has risks such as anesthesia-related complications, perforation of the uterus, injury to the cervix, excessive bleeding, and intrauterine infection. In addition, patients may experience a small amount of vaginal bleeding and cramp-like groin pain for a day or two after the procedure. Due to these disadvantages and risks, there is a need for intrauterine imaging procedures and devices that are easier to apply and do not require anesthesia and reduce post-procedure complaints.
  • the device of the invention provides the visualization of the three-dimensional structure of the inner surface of the uterus of the patient by moving into the uterine cavity.
  • the fact that the subject of the invention is the retraction rope is its most important advantage, which is different from the device presented in the document US8870757B2.
  • the fact that the subject of the invention can be moved freely in the uterine cavity with remote control is an important advantage compared to this application.
  • the imaging machine of the invention has been developed for the diagnosis and observation of gynecological diseases. It is quite different from the machine mentioned in this document.
  • the subject of the invention can enter the non-pregnant uterine cavity since it also includes system apparatuses that will deliver fluid to the uterine cavity.
  • the subject of the invention is remotely controlled by magnetism and magnet.
  • the subject of the invention has the ability to move freely in the liquid. For all these reasons, it is thought that the subject of the invention developed for gynecological procedures has novelty in the presence of this document.
  • the machine herein has a hydraulic drive mechanism that propels an imaging segment or a therapeutic segment through a narrow body lumen.
  • a wire retrieval mechanism removes the imaging segment or the therapeutic segment from the narrow stem lumen.
  • This machine is mostly used for imaging very narrow spaces such as the fallopian tube and works with a mechanism that is activated by using guide wires working with the principle of hydrostatic pressure.
  • This machine cannot move freely and cannot view the internal entrance of the cervix, which is the entrance part.
  • This machine allows treatment with the guidewire channel and increases the outer diameter of the catheter. This allows the user to control the amount and angle of light needed to capture a clearer image.
  • the fallopian tube cannot move freely in order to control it from within the uterus. It is seen that this device does not have much superiority over the hysteroscopy machine in imaging the inside of the uterus, as being controlled manually from the outside and having a camera system that moves with a guide at the tip of the apparatus.
  • the subject of the invention can be remotely controlled by magnetism and can move freely. The subject of the invention is different from this machine, which is used in the imaging of the fallopian tube, in terms of its purpose of use and its design.

  • the primary object of the invention is to develop an intrauterine imaging device that can display the uterine cavity in three dimensions, unlike hysteroscopy.
  • An object of the invention is to develop an intrauterine imaging device that allows to view the inner hole of the cervix (cervical internal os), which can more clearly display the niche (pocketing) in the uterus, which is called isthmocele.
  • Another object of the invention is to develop an intrauterine imaging device that can move in the uterus with the control of the probes and transmit the image without a cable.
  • a similar object of the invention is to develop an intrauterine imaging device that makes it easier for the surgeon to use the medical device and provides intrauterine imaging with smaller instruments and setups that require less setup instead of many surgical equipment required for hysteroscopy.

  • hysteroscopy performs imaging by transferring images taken via a wired camera to the screen. This system is presented in detail in Figure 1 .
  • the subject of the invention is designed for easier and clearer visualization of the inside and the whole of the uterus.
  • This device is a medical device assembly with an imaging camera placed in the capsule and a light source that illuminates the darkness in the cavity.
  • the capsule herein is preferably round and has dimensions of 7x20 mm.
  • an energy source and bluetooth communication elements are located for wireless data transfer with a computer.
  • (+) and (-) poles are placed at the two ends of the capsule so that it can be moved with probes outside the body.
  • the view regarding this is presented in Figure 2.
  • the imaging capsule must be produced from transparent, biocompatible polyethylene.
  • the main body consists of two parts. Thus, when necessary, necessary arrangements can be made to the interior of the capsule.
  • the biomedical medical device which is the subject of the invention, designed as uterine selfie, is expected to perform the function of hysteroscopy in a simpler, more useful and less invasive manner.
  • the hysteroscope can be performed in the outpatient clinic under office conditions, it has several disadvantages that trouble the surgeon, such as local anesthetizing the cervix before the procedure or performing the procedure under general anesthesia, and moving the hysteroscopy rod from side to side during imaging.
  • the machine developed in the subject of the invention it is planned to eliminate these disadvantages and to perform these functions by means of probes outside the body.
  • the subject of the invention is applied more simply than the hysteroscopy in the present art.
  • since local or general anesthesia will not be applied for the invention it is a less invasive application.
  • the control element is placed at the entrance of the vagina and after the serum inlet valve is opened from the vaginal fluid inlet channel, the inside of the vagina is filled with serum.
  • the image-taking process is started and the capsule placed at the end of the cannula is advanced through the vagina with the cannula, passed through the cervix and reached into the uterus.
  • serum flow takes place from the interacervical fluid inlet channel through the cannula.
  • the capsule is released through the cannula on which it is fixed and left in the uterine cavity. Serum flow continues until the uterine cavity is filled at the desired level.
  • the capsule is moved in the uterine cavity with the effect of the magnetic field, and the tissues can be observed in the desired proximity by moving it in the desired direction.
