Crile Clamp
Ratcheted ring-handled hemostat with full-length transverse serrations on a finer, more delicate jaw than the Péan — the workhorse small-to-moderate-vessel hemostat. Sits between the Kelly (distal-half serration, moderate jaw) and the mosquito (Halsted, very fine jaw) and is the most frequent point of confusion with the Kelly because the two are similar in size.[1][3]
Design
- Jaws: moderately curved (or straight), full transverse serrations the entire length of the jaw.
- Profile: finer and more delicate than the Péan; jaw bulk closer to a Kelly but with the Péan-style serration pattern.
- Tip: blunt; no interlocking tooth.
- Mechanism: ring-handled box lock with a multi-position ratchet.
- Length: standard 14 cm (5.5 in); 16 cm and longer for deeper exposure.
- Material: surgical-grade stainless steel.
Crile vs Kelly vs Péan
The three hemostats together form a continuum. The simplest mental model:
| Clamp | Serrations | Jaw bulk | Best fit |
|---|---|---|---|
| Crile | Full jaw, transverse | Finer / more delicate | Small-to-moderate vessels, refined hemostasis |
| Kelly | Distal half only, transverse | Moderate, curved | Moderate vessels, blunt dissection |
| Péan | Full jaw, transverse | Heavier / more robust | Larger pedicles, aggressive grip |
The Crile is the most-confused-with-Kelly pair on the tray. Serration length is the discriminator — a Crile bites uniformly across the jaw; a Kelly bites tip-first.[3]
Reconstructive-Urology and Urogyn Uses
- Hemostasis on small-to-moderate vessels during open RU work — bleeders during scrotal IPP / AUS / hydrocelectomy / varicocelectomy, perforator-flap dissection, inguinal lymph-node dissection adjuncts, dorsal venous complex tributaries, and peri-urethral bleeders.
- Pedicle clamping on small pedicles before ligation — superficial / external pudendal branches, scrotal cord tributaries, small adnexal pedicles during adjunctive hysterectomy.
- Blunt dissection along anatomic planes when a finer feel than the Kelly is required — peri-prostatic, retropubic, and recto-urethral planes during posterior urethroplasty exposure.
- Suture and drain control — clamping ligature ends mid-knot, securing Penrose / red-rubber drains, tagging suture ends to follow through a layered closure.
- Mid-shaft control of tubing — temporary occlusion of catheters or drains.
For finer vessels, drop down to a mosquito (Halsted); for larger pedicles or more aggressive grip, step up to the Péan; for interlocking tip-tooth purchase on fascia or pedicles for ligation, switch to the Kocher.
Technique
- Grip: thumb-and-ring-finger through the rings, index along the shank.
- Tip-first grasp: pick up the bleeder at the tip, close to the first ratchet, check for control, then tie or cauterize below the clamp.
- Blunt spread: like the Kelly, the closed Crile can be advanced into a tissue plane and opened to develop the plane — finer jaws make the Crile preferable for delicate planes (peri-urethral, peri-vasal, retro-pubic).
- Do not use on bowel, ureter, or any layer planned to remain in situ — full-length serrations are crushing.
Distinctions from Adjacent Hemostats
| Clamp | Serrations | Tip tooth | Best fit |
|---|---|---|---|
| Crile | Full jaw, transverse, finer | No | Small-to-moderate vessels, refined hemostasis |
| Kelly | Distal half, transverse | No | Moderate vessels, blunt dissection |
| Péan | Full jaw, transverse, heavier | No | Larger pedicles, aggressive grip |
| Mosquito (Halsted) | Full jaw, very fine | No | Fine vessels, delicate hemostasis |
| Mixter (right-angle) | Variable | No | Tunneling around vessels and pedicles |
| Kocher | Full jaw + 1×2 tip tooth | Yes | Fascia, dense scar, pedicles for ligation |
Historical Context
Named for George Washington Crile (1864–1943), one of the most consequential American surgeons of the late-19th and early-20th centuries — often called the "father of physiological surgery."[1][2] Crile's contributions span far beyond the hemostat that bears his name:
- Radical neck dissection (1905–06) — first successful en-bloc cervical lymph-node dissection for head-and-neck cancer; 75% 3-year survival vs 19% without block resection.[4][5]
- First successful direct human blood transfusion (St. Alexis Hospital, Cleveland, August 6, 1906) between two brothers, adapting Alexis Carrel's vascular-anastomosis technique; later carried into WWI battlefield medicine.[6]
- Anoci-association (anoci-anesthesia) — the precursor concept to modern multimodal pre-emptive analgesia and surgical-stress-response mitigation.[1]
- Routine intraoperative blood-pressure monitoring and first US use of cocaine for regional anesthesia.[1]
- Pneumatic anti-shock suit — the engineering forerunner of the aviator's G-suit.[1]
- Principal founder of the Cleveland Clinic (1921, with Bunts, Lower, and Phillips) on the group-practice model.[1][7]
- Founding member and second president of the American College of Surgeons (1916–17).[1]
He published over 400 papers and 24 books and died on January 7, 1943, of bacterial-endocarditis complications.[2]
