Randall Kidney Stone Forceps 21cm for Renal Stone Retrieval

Randall Kidney Stone Forceps 21cm, SKU PS-1361, are reusable urology forceps manufactured from German stainless steel for renal stone grasping, calyceal stone retrieval, renal pelvis access, stone fragment handling, and controlled extraction support during open urological procedures. The available size is 21cm, giving urology teams an extended working length for deep renal and urinary tract access. The image shows a long curved shaft, slim distal working jaws, serrated gripping surfaces, a box-lock joint, finger-ring handles, and a ratchet locking mechanism for maintained closure after placement.

Curved Urology Jaw Design

The working action is produced by two opposing distal jaws joined through a box-lock joint that transfers ring-handle compression into aligned closure. The curved shaft supports approach into deeper urology fields while keeping the handles away from the central operative corridor. Serrated distal gripping surfaces support controlled purchase on selected renal calculi, stone fragments, tissue-adjacent calculus material, and suture or dressing material when required during operative workflow. The 21cm length provides extended reach for open renal access, pyelolithotomy support, calyceal exploration, and renal pelvis stone handling. The ratchet near the handles locks at staged closure points, allowing the instrument to maintain grasp while suction, retractors, probes, irrigation, or adjunct forceps are active in the same field.

Renal Stone Retrieval Workflow

During open urology workflow, Randall Kidney Stone Forceps are applied after the renal pelvis, calyx, or target stone area has been exposed and visually identified. The curved working end is advanced toward the selected calculus or stone fragment, and the jaws are closed under controlled hand pressure. The ratchet is engaged only after the required grasp is reached. Urologists and operating room teams use this pattern during nephrolithotomy support, pyelolithotomy, renal pelvis exploration, calyceal stone removal, stone fragment retrieval, urinary tract tissue exposure, and closure-stage field management. The slim distal jaw profile supports controlled entry into restricted renal working spaces while preserving room for suction, retractors, irrigation, and assistant instruments.

21cm Size Selection

The 21cm size is selected when the surgeon requires extended reach for renal pelvis access, calyceal stone retrieval, or deep urinary tract exposure. This working length keeps the hand outside the main operative space while the distal jaws reach the target area. Randall Kidney Stone Forceps are suitable for urology trays, renal stone procedure sets, teaching laboratories, veterinary urology packs, distributor inventory, and institutional replacement programs. The single-size configuration simplifies procurement where a standard 21cm kidney stone forceps pattern is required for reusable open urology instrument sets.

German Steel Reprocessing and Procurement Documentation

German stainless steel construction supports repeated clinical use by maintaining jaw alignment, serration definition, corrosion resistance, box-lock stability, and ratchet function through cleaning and steam sterilization cycles. Satin, dull, and mirror finish options support procurement preferences for glare control, visual inspection, and existing urology tray standards. After use, the jaws should be opened and cleared of blood, stone debris, tissue residue, mucus, irrigant residue, dressing fibers, lint, and procedural debris before enzymatic cleaning. Processing can include manual brushing, ultrasonic decontamination, washer-disinfector exposure, rinsing, drying, box-lock inspection, ratchet review, serration inspection, jaw-tip inspection, packaging, and steam autoclave sterilization according to facility protocol.

How are Randall Kidney Stone Forceps different from standard dressing forceps?

Standard dressing forceps are used for general tissue, dressing, and material handling. Randall Kidney Stone Forceps are designed for urology stone retrieval, with a long curved working profile and distal grasping jaws suited for renal pelvis and calyceal access. The clinically relevant difference is procedural application, working length, jaw geometry, and the ability to grasp selected calculi or stone fragments during open urology workflow.

Why is the 21cm length useful?

The 21cm length is useful when the operative target lies deeper than a standard hand instrument can comfortably reach. In open renal procedures, this length helps keep the handle outside the main exposure while the distal jaws reach the renal pelvis, calyx, or stone-bearing area. The extended profile also helps preserve working room for suction, retractors, irrigation, probes, and assistant instruments.

What does the ratchet mechanism do?

The ratchet near the handles holds the jaws at staged closure points after placement. This allows Randall Kidney Stone Forceps to maintain controlled grasp while the surgeon uses suction, retractors, irrigation, probes, or adjunct instruments in the same operative field. Release is controlled by separating the ratchet teeth before reopening the jaws. Cleaning around the ratchet, box lock, serrations, and distal jaws is important because retained blood, stone debris, mucus, or lint can affect closure and release.

Are these forceps suitable for reusable sterile processing and distributor stock?

Yes, Randall Kidney Stone Forceps 21cm are reusable German stainless steel instruments suitable for hospital, clinic, urology, veterinary, distributor, surgical center, teaching lab, and operating room supply workflows. The 1-piece MOQ supports replacement ordering for urology trays, renal stone procedure sets, veterinary urology packs, teaching instruments, and institutional inventory programs. OEM availability supports distributor branding, institutional packing, and bulk purchasing programs. The 1-year warranty and return and replacement service support procurement teams managing recurring urology instrument replacement.
