Description

FEMALE GENITAL DESIGNER FIELD OF INVENTION

The present invention describes a female genital eyeliner. More specifically, it comprises an anteroposteriorly bent rod 5 instrument which allows the uterus to be projected to the anterior, posterior and lateral positions suitable for laparoscopic surgeries with procedures and or diagnosis, radiological examinations, hysterosalpingography and cromotubation, by means of exchange of parts and accessories. .

BACKGROUND OF THE INVENTION

For some interventions in gynecological laparoscopy, a uterine manipulator is indispensable.

Uterine manipulators are a kind of rod that allows mobilizing the uterine matrix. This system is introduced by the vagina while a camera is inserted into the patient's womb, the emitted image of which is projected on a monitor. The manipulator allows the uterus to be moved, making it possible to observe through the camera the possible affections in the matrix, being also used in operations where the uterus is removed, giving the best images and 20 positions.

The uterine manipulator provides, for example, in laparoscopic hysterectomy, a good presentation of the surgical field. Moreover, with the help of a uterine manipulator, the necessary tension can be produced to cut the various tissues (muscles, fascia, tendons and vessels).

In case of total laparoscopic hysterectomy, it is also necessary to have a good view of the uterine (bladder) and other organs in continuity or adherence, as well as the identification of the vaginal dome after separation of the uterus from the vagina.

For the correct placement of the uterine manipulator, it is necessary to perform a hysterometry, where the uterine cavity 5 is measured after clamping and traction of the cervix. Immediately afterwards, the uterine manipulator stem is inserted with an appropriate adapter for the desired surgical or diagnostic procedure.

The prior art describes various uterine manipulators, basically composed of a metal rod that is introduced into the endometrial cavity, a plastic cup that fits into the cervix, a fixation system so that the rod placed in the endometrial cavity does not exceed the limit indicated by the previous hysterometry and finally a cable for the assistant to handle the instrument. In hysterectomy procedures, an efficient sealing system of the installed pneumoperitoneum (vaginal plug) is still required.

Document BRPI0402814-7 describes a uterine manipulator equipped with a stainless steel tube or any other type of material with handle to which a stainless steel rod or any other type of length-adjustable material is fitted.

BRPI0301614-5 discloses an articulated uterine manipulator for videolaparoscopic total hysterectomy that provides a wide range of angular variations to facilitate movement of its extremities.

W02007129013 describes a semi-flexible variable length uterine manipulator that follows the cervical canal to avoid any risk of perforation and to provide excellent pelvic exposure regardless of the size, shape and position of the uterus.

US2009209973 describes an equipment for laparoscopic assisted vaginal hysterectomy comprising at one end a wrist and at the opposite end a manipulator, a diaphragm located at the distal end, said manipulator whose end is pivotable from the end of the wrist to allow manipulation from the womb.

US5840077 discloses a manipulator having a vaginal extender, a uterine manipulator and a flexible occluder that performs a movement relative to the manipulator axis during use.

EP0642766 describes a surgical instrument comprising a handle, an elongate member and a channel positioned on the elongate member for transporting fluid to the distal end portion of said elongate member, and a seal positioned on the outer surface of said elongate member.

The state of the art describes manipulators for predominantly straight gynecological surgeries, devoid of any curvature, or instruments having a hinged distal portion, enabling full mobility for correct uterine positioning. Still, some manipulators have a regulation of the length of the rod and others allow the exchange of tips and cups, available in various sizes, adapting the instrument to the patient's uterine cavity.

However, it is essential for uterine manipulators to clearly present the vaginal dome for the surgeon's visualization and guidance in the surgical field. State-of-the-art outlines, given the fact that they are straight, do not provide this visualization.

Thus, it is the object of the present invention to provide a female genital eyeliner with anteroposterior curvature which at a given stage of surgery or diagnosis turns in the postero-anterior direction without losing all the delineations necessary to elucidate the anatomical accuracy of organs, ensuring the continuation of intervention without or with minimal chances of complications.

SUMMARY

The invention provides a female genital eyeliner that features a single instrument capable of performing five procedures - diagnostic and / or interventional laparoscopic surgeries, radiographic examinations with or without procedures, hysterosalpingography and cromotubage.

The invention provides a female genital eyeliner that allows the clear presentation of the uterine and adnexal limits (ovary and fallopian tubes).

The invention provides a female genital eyeliner that minimizes the risk of injury during surgery by separating and enhancing anatomical precision with all organs and tissues.

The invention provides a female genital eyeliner that shortens surgical time by 50% or more, as it facilitates exposure of the uterus and attachments and, consequently, decreases the exposure time to infection.

The invention provides a female genital eyeliner that allows the

tip interchangeability for various procedures.

DETAILED DESCRIPTION OF THE INVENTION The female genital eyeliner, object of the present invention, comprises an instrument provided with a proximal end having a handle (10), a tubular intermediate portion with posteroanterior concavity (20) and distal end having a fixation means (30) of accessories for performing various procedures, such as diagnostic and / or interventional laparoscopic surgeries, radiological examinations with or without procedures, hysterosalpingography and chromotubation.

The handle (10) has an anatomical and non-slip configuration, said handle (10) can be fixed to the tubular intermediate portion (20) permanently or detachable, having a means of attachment, threaded fastening or quick coupling.

The tubular intermediate portion (20) has at the distal end (30) the arrangement of a means for securing conventional devices in gynecological procedures, such as a warhead for passage of liquids into the uterine cavity in cromotubation procedures, as shown in Figure 5. , and hysterosalpingography, as shown in Figure 6, intra-cavitary mandrel 5 for mobilization of the uterus in the surgical procedure and vaginal seal to maintain the pneumoperitoneum after surgical opening of the vagina in the hysterectomy procedures.

Optionally, between the handle (10) and the tubular intermediate portion (20), an area is provided with side sockets 10 (12) for clamping (200) enabling the cervix to be locked and pulled and, with locking said tweezers in the lateral inserts (12), ensure the perfect connection between the cervix and the female genital eyeliner, in said area (12) providing a valve (11) for the ingress of liquid, dye and / or air contrast. . The valve (11) is interconnected to an internal channel (21) in the tubular intermediate portion (20) through which the liquid, dye and / or air contrast that enters said valve (11) flows to be released at the distal end (30). ) of the female genital eyeliner.
