Description
- This is a non-provisional application based upon U.S. Provisional Patent Application Ser. No. 61/689,357, entitled “DAYLIGHT UNWEDGE FETAL HEAD LODGED IN BIRTH CANAL”, filed Jun. 5, 2012, which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to an obstetrical instrument, and, more particularly, to an obstetrical instrument for use during the birthing process.
- 2. Description of the Related Art
- It is not uncommon during the birthing process for a pregnant patient to reach full dilation of the cervix and begin pushing the fetus down through the birth canal only to have the fetus become lodged in the birth canal. Often a vacuum or forceps may be used to further assist the delivery. This may, however, worsen the situation by causing the fetus to become more firmly impacted or lodged in the birth canal without achieving delivery. After attempts of vaginal delivery are abandoned, the delivering physician must deliver the fetus through cesarean section.
- During the course of a cesarean section, the fetus must be positioned such that the physician can reach behind the head of the fetus to deliver the baby out of the uterine cavity through an incision made for purposes of delivery. Presently, the fetal head is often positioned for such delivery by an assisting physician or nurse. Such an assistant must insert his or her hand up through the birth canal and place his or her fingers against the fetal head to position the head such that the delivering physician can reach behind the head and gently deliver the baby out through the incision in the uterine cavity. Often in such cases, a surgical drape is placed over the legs of the patient and the assistant is essentially working blind under the sterile drape.
- The assistant who asserts the force to push the fetal head into position for the delivering physician does so with his or her fingers, which requires considerable force and is limited by the length of the assistant's arms and/or fingers, as well as by the assistant's physical strength.
- What is needed in the art is an obstetrical device which provides for a more efficient and safe delivery of a fetus.
- The present invention provides an obstetrical instrument, namely, a fetal head elevator, including an elongated handle and a fetal head support portion coupled with a distal end of the elongated handle.
- The invention further provides an obstetrical instrument, namely, a fetal head elevator including an elongated handle, an intermediate member coupled with a distal end of the elongated handle, and a fetal head support portion coupled with the intermediate member.
- Additionally, the present invention further provides a method of repositioning the head of a fetus during the birthing process. According to the method of the present invention, an obstetrical instrument, namely a fetal head elevator, is provided which includes an elongated handle and a fetal head support portion coupled with a distal end of the elongated handle. A distal end of the obstetrical instrument, namely the fetal head elevator, is inserted into the birth canal of a patient and is positioned such that the fetal head support portion of instrument is directly adjacent to the head of the fetus. A controlled pressure is then applied against the fetal head to reposition the fetal head from birth canal into the uterine cavity.
- An advantage of the present invention is that the inventive obstetrical instrument allows for the fetal head to be safely repositioned from the birth canal into the uterine cavity for delivery via cesarean section.
- Another advantage is that since the inventive obstetrical instrument allows for the fetal head to be elevated, the delivering practitioner is able to easily reach behind the head for a quick delivery with minimized risk of injury to the fetus and to the patient.
- A further advantage of the obstetrical instrument of the present invention is that the user can use two hands to exert a controlled pressure to slowly elevate the head of the fetus into position for a delivering physician to efficiently and safely deliver the fetus through an incision in a cesarean section.
- The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of an embodiment of an obstetrical instrument according to the present invention; -
FIG. 2 is a cross-sectional view of a fetal head support portion of the obstetrical instrument ofFIG. 1 ; -
FIG. 3 is an exploded sectional view of a second embodiment of an obstetrical instrument according to the present invention; -
FIG. 4 is an end view of an obstetrical instrument according to the embodiments illustrated inFIGS. 1 and 3 ; and -
FIG. 5 is a flow chart of a method of repositioning the head of a fetus during the birthing process. - Corresponding reference characters indicate corresponding parts throughout the several views. The exemplifications set out herein illustrate embodiments of the invention and such exemplifications are not to be construed as limiting the scope of the invention in any manner.
- Referring now to the drawings, and more particularly to
FIGS. 1 and 2 , there is shown anobstetrical instrument 10, namely afetal head elevator 10, which generally includes anelongated handle 12 and a fetal head support portion 14 (shown in cross section inFIG. 2 ). - At a
distal end 16 ofhandle 12 is a flaredportion 18 including a plurality ofopenings 20 extending therethrough. The plurality ofopenings 20 may be positioned in any arrangement around the flaredportion 18. Fetalhead support portion 14 also includes a plurality ofopenings 22 extending therethrough. The plurality ofopenings 22 of fetalhead support portion 14 are arranged such that when fetalhead support portion 14 is coupled withhandle 12, they are in fluid connection with the plurality ofopenings 20 extending throughflared portion 18 ofhandle 12. The plurality ofopenings 22 of fetalhead support portion 14 may, for example, be arranged to align with the plurality ofopenings 20 extending throughflared portion 18 ofhandle 12. - Alternatively, or in addition, a channel (not shown) may be formed within flared
portion 18 such that it intersects with each of the plurality ofopenings 20 in flaredportion 18 ofhandle 12 such that, regardless of the position of fetal head support portion, the plurality ofopenings 22 extending therethrough are in alignment with the channel (not shown), and thus in fluid connection with the plurality ofopenings 20 extending throughflared portion 18 ofhandle 12. Advantageously, the obstetrical instrument according to the present invention allows for fluid, for example air, to flow freely through theobstetrical instrument 10 such that no vacuum is created betweenobstetrical instrument 10 and the head of a fetus during use by a practitioner. - Fetal
head support portion 14 is coupled, for example fixedly coupled or releasably coupled, withdistal end 16 ofelongated handle 12. More specifically, fetalhead support portion 14 is coupled with flaredportion 18. Any of a number of known mechanisms may be utilized for couplingdistal end 16 ofelongated handle 12 with fetalhead support portion 14. Fetalhead support portion 14 may, for example, be coupled withelongated handle 12 with an adhesive. Alternatively, corresponding male and female threads (not shown) included on thedistal end 16 ofelongated handle 12 and fetalhead support portion 14 may be utilized to releasably couple the components. Fetalhead support portion 14 may further include a fixation ring and/or at least one flange for affixing it to distalend 16 ofelongated handle 12. - Further, according to the present invention, fetal
head support portion 14 is formed of a flexible material configured to cushion and support the head of a fetus whileobstetrical instrument 10 is in use. The flexible material must be sufficiently flexible or resilient such that damage to the fetal head is avoided despite the application of pressure across the surface area of the fetalhead support portion 14. The flexible material may, for example, have a Shore A hardness in a range between approximately 30 and 50. If the flexible material is a foam, the foam density is, for example, between approximately 3 and 5 pounds per cubic foot (lb/ft3). The fetalhead support portion 14 may, for example, be formed of or covered with a sterile foam material and/or sponge material. Exemplary materials from which the fetalhead support portion 14 may be covered with or formed of include polyurethane foam, cotton, rayon, polyester or any resilient antimicrobial foam. The fetalhead support portion 14 is substantially disc-shaped such that when theobstetrical instrument 10 is in use force exerted by the user of the device is spread across the disc's surface area, rather than focused at a single point, such as is the case, for example if a practitioner must use his or her finger(s) to reposition the head of a fetus. -
Handle 12 ofobstetrical instrument 10 may be formed of any material known in the art for surgical instruments. For example, the handle may be formed of stainless steel, urethane, silicone, polyurethane, titanium or other known surgical grade polymers and metals.Elongated handle 12 is formed such that it has a gentle curve to accommodate the natural curvature of a pelvis.Elongated handle 12 may further include abulbous portion 24 at aproximal end 26 ofhandle 12.Bulbous portion 24 advantageously helps to assure that the user's hand does not slip off of obstetrical instrument's 10handle 12 during use.Handle 12 further includes agrip portion 28 which may be in any known configuration in the art which preventsobstetrical instrument 10 from slipping while in use, despite encountering the inevitable moisture from body fluids during the birthing process. For example,grip portion 28 may include a plurality of ridges extending around an outer circumference ofhandle 12.Handle 12 may also include aridge 30 extending along a superior aspect ofhandle 12 in a direction parallel with a longitudinal axis of theelongated handle 12.Ridge 30, ordirectional ridge 30, serves as a directional indicator to mark the top of the device, thus allowing the individual maneuveringobstetrical device 10 to have a tactile sense of the position of the device for situations when a visual sense of position is not feasible, for example, due to the use of a sterile drape during a cesarean section. - Referring now to
FIG. 3 , there is shown a second embodiment of anobstetrical instrument 40 according to the present invention.Obstetrical instrument 40 has substantially the same structure of the first embodiment ofobstetrical instrument 10 discussed more fully above. The primary difference ofobstetrical instrument 40 is that anintermediate member 42 is provided which includes a disc-shapedportion 44 which includes a plurality ofopenings 46 extending therethrough and which are arranged such that they are in fluid alignment withopenings 20 in flaredportion 18 of handle andopenings 22 in fetalhead support portion 14 when assembled. Accordingly, in use, the aligned openings (20, 22 and 46) provide a fluid passage such that no vacuum is created between theobstetrical device 40 and the fetal head. - According to this embodiment of
obstetrical instrument 40, fetalhead support portion 14 is releasably coupled with disc shapedportion 44 ofintermediate member 42. It is, however, feasible for fetalhead support portion 14 to be fixedly coupled with disc shapedportion 44 of intermediate member, for example using an adhesive. When assembled,intermediate member 42 is fixedly or releasably coupled withdistal end 16 ofhandle 12, for example with flaredportion 18 ofhandle 12. -
Intermediate member 42 may be firmly coupled withhandle 12 using any number of known coupling or fastening mechanisms, for example a key lock system, a cam system or a ball and socket mechanism, such as that illustrated inFIG. 3 . According to the embodiment ofobstetrical device 40 illustrated inFIG. 3 ,intermediate member 42 includes at its proximal end aball 48 configured for being received in a correspondingsocket 50 formed inhandle 12. - Referring now to
FIG. 4 , there is shown an end view of anobstetrical instrument openings 22 in fetalhead support portion 14. Althoughopenings 22 are arranged in a generally circular pattern around a central point of the generally disc-shaped fetalhead support portion 14,openings 22 may be arranged in any number of ways, as long as they are in fluid communication with corresponding openings in theintermediate member 42 and/or flaredportion 18 ofhandle 12, depending upon the embodiment. The edge of the fetalhead support portion 14 which would come into contact with a patient's vaginal tissue and/or bladder is sufficiently smooth such that it easily slides along the tissue, thus preventing injury to the bladder and/or vaginal tissue of the birth canal. - The present invention further provides a
method 60 of repositioning the head of a fetus during the birthing process, in other words during childbirth. Referring now toFIG. 5 , there is shown a flow chart illustrating the steps of themethod 60 according to the present invention. An obstetrical instrument is provided atstep 62 which includes an elongated handle and a fetal head support portion coupled with a distal end of the elongated handle. A distal end of the obstetrical instrument is inserted into the birth canal of a patient atstep 64. The fetal head support portion of the obstetrical instrument is positioned directly adjacent the head of a fetus atstep 66. A controlled pressure is applied against the fetal head with the obstetrical instrument atstep 68 to reposition the head of the fetus through the birth canal into the uterine cavity. The obstetrical instrument allows the user to ease the act of elevating the fetal head for purposes of delivery through a cesarean section. More specifically, the obstetrical instrument allows the user to slowly push the fetal head up to the point where a delivering physician can reach below the fetal head and complete the delivery. - Although the obstetrical instrument of the present invention has been described for use in a childbirth environment, it may have additional applications in the veterinary field for the comparative birthing process.
- While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
