Ovum Forceps: Close-Up with Gynecologic Acccuracy

 1. Introduction

Amongst all the seas of complicated gynecologic and obstetric surgical instruments there are, few as uncommon that have remained clinically valuable for centuries as ubiquitous as the ovum forceps. Even though they seem simple in design, they’ve proven to be a wise addition to a surgeon’s fingers to allow safe removal of intrauterine material, polyps, RPOCs, etc. The forceps ovum is more than a piece of surgical equipment — it is a tool of exactness that bridging the delicate art of tissue manipulation and science of clinical security.

Their use varies from elective procedure, i.e., dilation and curettage (D&C) or manual vacuum aspiration (MVA), to emergency procedure like control of postpartum hemorrhage. The richness and extent of anatomical, surgical, and clinical detail in ovum forceps — varying from invention and technical designs to procedural application subtleties, innovation, and complications — is addressed under this blog.

2. Historical Background

Instrumentation in gynecology traces its history back to ancient times. Hippocrates and Soranus of Ephesus have already documented plain obstetric instruments. But eventually, much later, i.e., during the 18th and 19th centuries, ovum forceps became standardized after the medical fraternity came to realize intrauterine, aseptic manipulations. The instruments were initially applied in the management of miscarriages and uterine evacuations for retained tissue. Their history was towards safe surgery and obstetrics with the foundation of modern gynecology.

Historic highlights are:

•Early medieval obstetric application of long-handled forceps.

•Development throughout the 1800s for uterine evacuation.

•Construction of sterilizable metal instruments with curved tips and rounded fenestrated blades to fight tissues.

3. Ovum Forceps Design and Anatomy

Ovum forceps are specifically constructed for precise but firm intrauterine tissue pickup without cutting. Their most critical role is catching soft tissue without slippage or trauma. Their chief anatomical features are:

•Length: Typically between 22 to 30 cm to permit uterine cavities to be accessed.

•Shaft: Long, cylindrical, and tapers with gentle curvature to be able to fit uterine anatomy.

•Jaws: Oval or rounded to prevent perforation.

Fenestrated or smooth to provide a firm grip over delicate tissue.

•Handles: Spring-loaded or ratcheted to permit controlled pressure.

•Material: Surgical grade stainless steel or autoclavable polycarbonate in certain disposable configurations.

Functional Characteristics

• Un serrated jaws to prevent perforation or cutting of tissue.

• Different hinges so that increased mobility is enabled.

• Ergonomic handles in order to make proper handling easy by changing anatomical angles.

4. Types of Ovum Forceps

There are some types of ovum forceps based on anatomy and procedure. They are:

• Bozeman Forceps

Curved shape to allow greater intrauterine access.

Staple in postpartum operation.

• Foerster Sponge Forceps

Blunt, rounded tips, used interchangeably with ovum forceps to remove tissue.

• Kevorkian Forceps

Smaller with serrated jaws used to cervical or endometrial biopsy.

• Randall Forceps

Firm grip with curved tip, used with uterine curettes.

• Doyen Forceps

Lightweight with fenestrated blades used for thicker tissue.

All have specific use depending on uterine content, uterine cavity size, and urgency of procedure.

5. Indications and Uses

Ovum forceps are strongly indicated in a wide range of diagnostic, therapeutic, and emergent obstetric and gynecologic disorders:

Gynecological Applications:

• During the removal of retained products of conception (RPOC) following miscarriage or abortion.

• Evacuation of endometrial polyps.

• Removal and identification of intrauterine devices (IUDs).

• To facilitate dilation and curettage.

• Harvest of tissue for histopathology.

Obstetric Applications:

• Evacuation of placental residues after delivery to avert bleeding.

• Self-retained uterine evacuation in postpartum hemorrhage (PPH).

• Backup with intraoperative use in cesarean section where access is lost.

Surgical Support:

• Backup to laparoscopic or hysteroscopic procedure.

• Excision of tissue in myomectomy or polypectomy.

6. Step-by-Step Procedure: Handling and Use

Manipulation of ovum forceps requires care, knowledge of anatomy, and asepsis. The following is a general procedural protocol:

Pre-procedure Setup:

• Verification of indication with ultrasound or hysteroscopy.

• Patient consent and pre-procedure planning (e.g., misoprostol for ripening cervix).

• Aseptic practice and sterile field.

Instrument Manipulation:

• Pass speculum and grasp cervix with tenaculum.

• Cautiously dilate cervix (if not previously dilated).

• Stepwise gradual insertion of ovum forceps into uterine cavity under ultrasonographic guidance, if available.

• Open mouth slowly and grasp target tissue between the jaws.

• Close mouth and withdraw forceps slowly while maintaining a firm but atraumatic grasp.

• Repeat repeatedly until evacuation is complete.

• Finish by suction or curettage.

7. Safety, Risks, and Complications

Ovum forceps are safe but anatomical abnormality or misuse may lead to complications.

Common Complications:

• Uterine perforation (with deep or forceful insertion).

• Insufficient evacuation, particularly if contents are too small or fragmented.

• Cervical trauma, particularly in nullipara with hard cervix.

• Infection, if sterile technique is breached.

• Hemorrhage due to inadequate evacuation of the tissue or uterine atony.

Prevention Measures:

• Employ the use of ultrasound guidance in high-risk situations.

• Avoid the application of forcible action.

• Employ pre-dilation methods (pharmacologic or mechanical) at all times.

• Employ curved models for anatomical accommodation.

8. Similarity with Other Instruments

Ovum forceps are likened to other intrauterine devices. The similarity is as follows:

• Curettes:

Less traumatic, typically sharp, for scooping and not for grasping.

• Suction cannulae:

Innocuous in vacuum aspiration, best when employed with fluid and shattered tissue.

• Sponge forceps

Less effective but useful with hard tissue.

• Ring forceps:

Servile to some uterine evacuations but less catching and curved.

Advantages of ovum forceps:

• Better control of the removal of tissue.

• Less risk of uterine perforation than curettes.

• Best grip and control.

9. Advances and Modern Uses

Ovum forceps have also been utilized for minimally invasive and robot-assisted surgery since technology improved.

Recent Advances

• Single-use sterile ovum forceps: To reduce infection risks.

• Hybrid polymer-metal devices: Improved flexibility and grip.

• Robot-assisted models: Fewer errors in laparoscopic gynecological operations.

Clinical Uses:

• For infertility management during oocyte and embryo extraction (using ovum aspiration forceps).

• Included in post-abortion care worldwide as part of uterine evacuation kits.

• As an accompaniment for hysteroscopic telescopes for vision-aided polyp or foreign body excision.

10. Conclusion

Ovum forceps is a perfect illustration of the way an everyday surgical instrument becomes a pillar of high-tech medical practice. Its continued use in contemporary obstetrics and gynecology testifies to the impeccable versatility and safety of the device. From the evacuation of retained products of conception to the evacuation of polyps or foreign body, ovum forceps continue to be a pillar between minimal manipulation and therapeutic intervention. As surgery gets more digital and patient-specific, it is conceivable that the fundamental intent behind such antiquated equipment will be supplemented — not supplanted — by technology.

To be skilled in the ovum forceps is not so much to show technical skill; it is a sign of clinical maturity, deft working capacity, and subtle knowledge of women’s anatomy. Its legacy is not so much what it removes, but in what it leaves, and in the lives that it saves, protects, and improves.
