Definitions
- the present invention relates to an uterine cervical canal dilatation device and an associated speculum for dilating the cervix, facilitating examinations, diagnostics and surgical procedures within the uterus.
- This disposable medical device belongs to the field of application of medicine and medical instruments.
- This medical device is used for interventions in gynecology, specifically to expand the cervical canal, examine and pass instruments for all examinations and surgical procedures performed in the uterine cavity. It allows you to safely expand or dilate the cervical canal.
- Hegar candles have been around since 1879 and have never been upgraded or replaced. They are in the form of metal or plastic spacers. After grasping the cervix with forceps and pulling it outward, the practitioner introduces Hegar's first candle by pushing hard to spread the cervical canal. It begins with a small diameter, then introduces the following candles usually numbered 2 to 12 mmm one after the other. The first candles are the most dangerous because, because of their small size, they often cause lacerations or perforations of the cervical canal, leading to risks of internal bleeding. This is why these high-risk acts are performed in the operating room and involve costly surgical procedures.
- the invention of this medical device solves the manufacturing problems usually encountered in the design of medical devices for gynecological examinations and procedures. By its simplicity of operation and use, it also allows the dilation and protection of the cervical canal by avoiding all possibilities of damaging, lacerating or perforating the collagenous tissues and muscle fibers that surround the cervical canal in women.
- the invention relates to a device for dilatation of the uterine cervical canal, comprising:
- a dilator rod mounted in translation in the support
- the dilator rod thus makes it possible to dilate the cervical canal during its translation inside the extensible protective tube, the latter making it possible to protect the uterine cervical canal from friction of the dilator shaft in translation.
- the tubular portion of the dilator sleeve holds the fin guide and the expandable protective tube apart and forms a protective channel to prevent contact and damage to the cervical canal during the passage of diagnostic and surgical instruments.
- the dilator rod comprises at one end a guide rod connected by a series of portions of different sizes to a tube of the dilator rod, the size of the portions decreasing from the tube to the guide rod, for example from 12 to 2 mm, the guide rod having a diameter substantially equal to 2 mm.
- the dilatation of the uterine cervical canal is obtained gradually, between 2 and 12 mm.
- the tube of the dilator rod comprises a slot in which slides a transverse guide rod, the support having hooks adapted to engage with the transverse guide rod on each side of said tube of the dilator rod.
- the support comprises a narrowing portion forming an end stop in translation of the dilator rod in the support, the displacement in translation being for example substantially equal to 50 mm.
- the tubular portion of the dilator bushing is secured to a conical portion abutting in the narrowing portion of the support at the end of travel in translation of the dilator rod.
- the conical portion of the dilator bushing comprises two windows in which are adapted to be introduced respectively two protrusions of the dilator rod during a withdrawal, by the dilator rod, the dilator sleeve out of the finned guide housed in the extensible protective tube.
- the fin guide comprises several fins, and for example five fins, mounted on a conical portion of the fin guide, and movable between a rest position, in which the fins are collected and held tight inside the tube. extensible protector, and an expansion position, wherein the fins, after separation by the dilator rod, are held apart by the expansion sleeve inside the expandable protective tube.
- the fins have on an external part excrescences, and for example three excrescences per fin, cooperating in the expansion position with a widened cylindrical portion of the extensible protective tube.
- the excrescences cooperating with a widened cylindrical portion of the expandable protective tube allow the practitioner, by changing the position of the dilator after positioning and dilation of the uterine cervical canal, to adjust the position of the uterus and thereby facilitate the endoscopic vision of the uterus. uterine cavity.
- the invention relates to a vaginal speculum comprising an extended body of a handle, forming a housing for supporting a uterine cervical canal dilation device as described above.
- the body of the vaginal speculum comprises an upper spoon and a lower spoon mounted on a conical ring, the ends of the lower and upper spoons respectively clipping in two grooves engraved on the support of the dilator device of the uterine cervical canal.
- vaginal speculum has similar features and advantages to those described above with reference to the cervical cervical canal dilatation device.
- the invention relates to a disposable medical device which is integrated with a speculum of new design and in which is fixed the extensible protective tube support, allowing expansion from 2 to 12 mm safely.
- This extensible protective tube covers the cervical canal to prevent any traumatic contact on the walls during the passage of hysteroscopic instruments and surgery, also avoiding any contribution of vaginal bacteria in the uterus.
- This medical disposable device is composed of the various elements presented above to ensure the aforementioned advantages.
- the selling price of this device will be positioned so that it does not exceed half the cost price of a sterilization of the instruments it replaces: metal speculum, set of Hegar candles, stainless steel clip.
- the dilatation is done inside an extensible protective tube protecting the cervical canal from friction causing wounds and bleeding during the dilatation.
- This device by its invention and its easy use, allows all gynecologists to practice cervical dilatation.
- the speculum to dilate the cervical canal completely solves the problem of cervical dilation by avoiding any contact and damage or injury of the tissues of the wall of the cervical canal. It also prevents the perforation of the uterine walls.
- this device While facilitating interventions within the uterine cavity, this device is designed for single use.
- this medical device is designed to be integrated with a vaginal speculum. Thanks to the extendable protective tube deposited on the walls of the canal, it creates a protective tunnel between the entrance of the vagina and the uterine cavity thus preventing any contribution of vaginal bacteria brought by the instruments used.
- the dilation is effected by the pressure exerted on the dilator stem by the thumb of the practitioner that he will have previously inserted into the ring at the back of the dilator shaft.
- the dilator shaft penetrates and dilates the cervical canal.
- Plastic fins placed between the expandable protective tube and the dilator shaft separate the extensible protective tube to prevent contact, frontal resistance and friction of the dilator shaft on the wall of the cervical canal. This same action simultaneously deposits the plastic dilator sleeve that will shroud the cervical canal and protect it during the entire duration of the procedure. This dilator sleeve keeps spread the extensible protective tube and forms a tunnel that will also allow the practitioner to remove the dilator rod.
- this dilator sleeve is removed using the same dilator rod by turning a quarter turn on the right and pulling on the back to remove it. This will result in lowering the pressure of the cervical muscles and thus allow to remove the entire complete device with ease and security.
- the penetration of the dilator rod is limited to a maximum of 50 mm by a stop formed by a narrowing of a conical portion located inside the support of the extensible protective tube.
- the average length of the cervical canal varies between 25 and 35 mm.
- the end of the penetrating portion of the dilator shaft is round and flexible and will therefore bend if there is contact with the walls of the uterine cavity to prevent laceration and / or perforation.
- One of the main advantages of this invention is its ease of use and application.
- the semi-rigid end (diameter 2 mm) of the dilator shaft is presented on the opening of the cervical canal (naturally open between 3.5 and 4.5 mm) and penetrates without effort and resistance in the cervical canal by pressing on the back of the support.
- the extensible protective tube is placed in the cervical canal.
- the practitioner, pushing on the ring of the dilator shaft dilates the cervical canal and positions the dilator sleeve inside the extensible protective tube allowing access of the intervention instruments in the uterine cavity. Then he removes the dilator rod and can begin his intervention.

- the handle of the transverse guide rod 64 locks the assembly on the back of the support 3 with the help of the protuberances 312 and 322.
- the support 3, the guide rod 69, the expandable protective tube 8, the fin guide 7 and the fins 71 form an assembly whose end is introduced into the cervical canal ready to receive the end of the dilator rod 6 having the role of expanding the fins 7 and the extensible protective tube 8 and position, in same time, the dilator sleeve 5 which will create the protection tunnel during the intervention.
- the guide rod 69, located inside the dilator rod 6, and the dilator rod 6 will be removed at the same time leaving the free passage for the instruments.
- the dilator sleeve 5 will be easily removed from the cervical canal by re-introducing the dilator shaft 6 and turning it slightly to the right. Once hooked on the windows 52 and 53 located on the conical rear portion of the sleeve 5. It will be sufficient to pull the dilator rod 6 back, which will have the effect of narrowing the finned guide 7 and the fins 71, as well as the extensible protective tube 8 and thus allow the entire device to be removed from the cervical canal and the vagina. This device will then be deposited in the medical waste container.
- the gynecologist takes the sterile speculum packaging to dilate the cervix, facilitate diagnostic examinations and surgical procedures inside the uterus.
- this main packaging will be packaged separately, on the one hand, the body of speculum 1 with handle 2 made of medical plastic.
- the dilator rod 6 in which will already be positioned the guide rod 69 and the dilator sleeve 5. This assembly will be positioned in the support 3, and hooked with the aid of the transverse guide rod 64 in the protrusions 312 and 322.
- the fin guide 7 and the fins 71 also made of medical plastic, covered with extensible protective tube 8 made of medical materials.
- the assembly will be locked by the locking ring 9 on the conical end 37 of the support 3.
- To use the gynecologist takes the spoons 12 and 13 between the thumb and index finger folded to bring the ends 121 and 131 to introduce the speculum into the vagina by pushing it forward. Once the speculum is introduced into the vagina, it automatically deviates. Then it positions the lamp (FIG 3a) by housing it in the rear hollow portion of the handle 21 and adjusts the light flux 27. This light input will allow it to direct the entire support 3 and position the front part in the opening of the cervical canal.
- the gynecologist pushes with his thumb on the tapered rear part of the support 3 and pushes it completely into the conical rear part of the body of the speculum 1, which guarantees that the Guide rod 69 will completely introduce into the cervical canal to the entrance of the uterus the extensible protective tube assembly 8, the finned guide 7 and the fins 71.
- the gynecologist will introduce his thumb in the ring 61 positioned on the rear of the dilator shaft 6, and will perform a progressive push before abutting against the limiter or portion of narrowing 33 Then, pulling the ring 61 back, the gynecologist effortlessly removes the dilator rod 6 at the same time as the guide rod 69, which has the effect of clearing the passage for the various instruments to the uterine cavity through the extensible protective tube 8.
- the gynecologist again introduces the dilator rod 6 to abut against the conical portion of the sleeve 5, he slightly rotates the rod 6 on the right to pick the windows 52 and 53 with the excrescences 651 and 652. Then the gynecologist removes the assembly with the sleeve 5 and releases the tension exerted on the finned guide 7, the fins 71, and the extensible protective tube 8. This allows to remove effortlessly the entire device with all its integrated elements that will be deposited in a medical waste container.
