Ring (Sponge / Foerster / Rampley) Forceps

Long, ratcheted ring-handled forceps with large oval or circular ring tips — the workhorse instrument for vaginal preparation, packing placement, sponge-stick blunt dissection, cervical stabilization, and grasp of the Kittner (peanut) dissector. Sometimes named Foerster (Friedrich Foerster) or Rampley (Hugh Rampley) for design variants but used interchangeably in the operating room as "ring forceps" or "sponge forceps."

Design

• Tips: large oval or circular ring jaws (rather than flat or toothed) — may be smooth or have fine serrations on the inner surface.
• Mechanism: ring-handled box lock with a ratchet; holds the sponge or tissue without sustained hand pressure.
• Length: typically 18–25 cm (7–10 in); long variants reach the vaginal apex from below or the deep pelvic field from above. Straight and curved configurations available.
• Material: surgical-grade stainless steel; reusable autoclavable.

The ring tips distribute pressure across a broad rim instead of a single point or platform — the same atraumatic principle that governs the Babcock clamp but applied to a sponge or a tissue surface rather than a hollow viscus.

Reconstructive-Urology and Urogyn Uses

Vaginal preparation and skin prep

• Sterile prep painting of the perineum, vulva, and vaginal canal at the start of every vaginal and perineal RU/urogyn case. Sponge soaked in chlorhexidine or povidone-iodine is gripped in the ring jaws and used to paint from inside out.
• Operative-field prep of the scrotal, suprapubic, perineal, and inguinal skin.

Vaginal packing placement and removal

• Insertion of vaginal packing at the end of anterior / posterior colporrhaphy, sacrocolpopexy, fistula repair, posterior urethroplasty (transperineal), and prolapse repair — the ring forceps advances each turn of the packing to the apex without dragging the prior turn out.
• Removal of vaginal packing on postoperative day 1 — gentle traction in the ring jaws on the lead of the packing strip.

Sponge-stick blunt dissection

• A folded surgical sponge gripped in the ring jaws becomes a sponge stick — used for blunt-plane development in deep pelvic dissection (retropubic space, recto-vaginal plane, vesico-vaginal plane), open BNR, augmentation, diversion, sacrocolpopexy, and posterior urethroplasty.
• The sponge gives more spread force per unit area than a Kittner and is preferred when the surgeon needs to develop a larger plane quickly.

Cervical / vaginal-cuff stabilization

• Cervical grasp during office or operative procedures as an atraumatic alternative to the single-tooth tenaculum — IUD placement, endometrial biopsy, colposcopy-directed biopsy, vaginal-cuff inspection after hysterectomy.
• The Allis-vs-tenaculum RCT evidence framework (Andrews 2023, see Allis) translates to ring forceps as well — ring forceps grip the cervix with the broadest, most atraumatic footprint of any of the candidate instruments.

Kittner-handle and peanut grasping

• The standard "handle" for the Kittner / peanut dissector — peanut compressed into the ring jaws, locked to the first ratchet, then used as an atraumatic dissector along anatomic planes.

Foreign-body retrieval

• Retained vaginal foreign bodies, vaginal-cavity stones, post-pessary granuloma debridement, and post-fistula packing retrieval.

Other

• Drape securement in some institutional traditions.
• Wound-cavity inspection with a sponge-tipped ring forceps as an absorbent probe.

Technique

• Grip: thumb-and-ring-finger through the rings, index along the shank.
• Sponge or peanut loading: open the jaws, place the sponge or Kittner symmetrically across both ring tips, close to the first or second ratchet — third-ratchet crush over-compresses the sponge and reduces its working volume.
• Vaginal packing: lead the first turn of packing to the apex, release, regrasp the next exposed loop, advance — repeat until the apex is filled and the packing is at the introitus.
• Blunt dissection: sponge-stick technique — push along the plane, opening only enough to apply tension; do not "spread to dissect" the way one would with a Kelly. The sponge does the work, not the jaws.
• Cervical grasp: tangential bite of the anterior lip; first ratchet only — avoid full crush on cervical tissue.

Distinctions from Adjacent Instruments

Instrument	Tip	Best fit
Ring forceps (Foerster / Rampley)	Large ring jaws	Prep, packing, sponge-stick dissection, Kittner handle, atraumatic cervical grasp
Allis clamp	Short interlocking teeth	Skin, fascia, vaginal cuff, resected tissue
Babcock clamp	Smooth fenestrated	Bowel, ureter, hollow viscera
Single-tooth tenaculum	One sharp tooth	Cervical traction (more bleeding than Allis or ring forceps)
Singley thumb forceps	Fenestrated thumb forceps, no ratchet	Bowel / peritoneum, handheld
Kittner dissector	Peanut-shaped cotton/gauze sponge	Held in a ring forceps for soft blunt dissection

Naming

The instrument is variously named for Friedrich Foerster (German surgeon) and Hugh Rampley (British surgeon), reflecting parallel European design lineages; in operating-room parlance the design distinctions are largely lost and "ring forceps" or "sponge forceps" covers the whole family.
