Peapod Intervertebral Disc Rongeur for 2–4mm Angled Spinal Disc Retrieval

Peapod Intervertebral Disc Rongeur, SKU PS-9360, Model PS-9360, is a spinal and orthopedic disc rongeur manufactured from German stainless steel for controlled intervertebral disc retrieval, annular window access, and removal of fibrocartilaginous fragments through confined operative corridors. The available variants are 2.5mm Angled Up 7", 3.0mm Angled Up 7", 4.0mm Angled Up 7", Small 2.0mm Angled Up W/L 5-1/2", 2.5mm Angled Up W/L 5-1/2", 3.0mm Angled Up W/L 5-1/2", and 4.0mm Angled Up W/L 5-1/2". The instrument has a long slender shaft, peapod-style cup jaws, angled-up distal working end, ring handles, pivoted closure mechanism, and shaft channel that transfers finger compression to the jaw tips. It is used in lumbar discectomy, cervical discectomy, microdiscectomy exposure, laminotomy-assisted disc removal, posterior decompression, contained fragment extraction, and intervertebral space debridement. This rongeur supports neurosurgeons, spine surgeons, orthopedic surgeons, hospital operating rooms, ambulatory surgical centers, and procurement teams maintaining reusable spine trays.

Peapod Cup Jaw Capture and Ring Handle Control

The instrument works through a long-shaft grasping mechanism that transfers ring-handle compression to the distal peapod cup jaws. The cup profile encloses selected disc material, annular fragments, nucleus pulposus, or loose fibrocartilaginous tissue before withdrawal through the operative corridor. The angled-up working end changes the bite direction so the surgeon can engage superior disc recesses, cranially positioned fragments, and tissue sitting above the direct shaft axis without excessive wrist rotation. The slender shaft preserves working space for nerve root retractors, suction, irrigation, microscope positioning, and adjacent spine instruments. The pivoted closure mechanism aligns the cups during insertion, capture, withdrawal, release, and repeated repositioning. Ring handles support controlled finger placement during precise passes inside a narrow disc space. The 5-1/2" and 7" working options allow the surgeon to match shaft reach to exposure depth. This design is used for disc fragment retrieval rather than laminar punching or heavy bone cutting.

Disc Removal Workflow in Spine Surgery

In operative workflow, Peapod Intervertebral Disc Rongeur is introduced after exposure, hemostasis, retraction, annular access, and identification of the target disc material. During lumbar discectomy, the selected angled-up cup is advanced through the annular window to grasp loose nucleus pulposus, contained fragments, or residual fibrocartilaginous tissue after decompression has begun. In microdiscectomy, the slender shaft assists access through a limited laminotomy window while microscope or loupe visualization guides distal placement. During cervical disc procedures, the shorter 5-1/2" working length supports controlled access where the operative corridor is compact and hand movement is restricted. In posterior decompression, the 7" versions provide additional reach after bony access has been created with Kerrison rongeurs and neural structures are protected with retractors. The angled-up jaw is useful for cranial recess retrieval without changing the main hand position. The instrument is used with Penfield dissectors, nerve root retractors, Kerrison punches, pituitary forceps, curettes, suction tubes, bipolar forceps, irrigation instruments, and hemostats.

2.0mm 2.5mm 3.0mm and 4.0mm Variant Selection

The Small 2.0mm Angled Up W/L 5-1/2" variant is selected for narrow cervical access, limited laminotomy windows, fine fragment retrieval, and disc material close to protected neural tissue. The 2.5mm Angled Up 7" and 2.5mm Angled Up W/L 5-1/2" options provide controlled bite volume for small lumbar or cervical fragments where precision remains the main priority. The 3.0mm Angled Up 7" and 3.0mm Angled Up W/L 5-1/2" variants support routine disc retrieval when the annular opening allows a moderate cup width. The 4.0mm Angled Up 7" and 4.0mm Angled Up W/L 5-1/2" options are selected for larger accessible fragments where broader capture improves retrieval efficiency. Across all variants, the angled-up cups provide directional engagement, the shaft maintains access, the pivot transfers closure force, and the ring handles provide controlled extraction. Selection is based on disc level, fragment size, exposure depth, annular window width, and proximity to neural structures.

Reusable German Steel and Procurement Documentation

German stainless steel provides the rigidity required for repeated cup closure, shaft alignment, tissue capture, and operating room reprocessing. The reusable construction supports surgical workflows involving manual cleaning, ultrasonic cleaning where used, drying, inspection, packaging, and steam autoclave sterilization between procedures. Satin, dull, and mirror finish options support operating room and sterile processing preferences; reduced-glare surfaces assist visibility under surgical lighting, while mirror surfaces support visual inspection after cleaning. Reprocessing focuses on the peapod cup jaws, distal hinge, shaft channel, pivot recesses, ring handles, and internal closing surfaces because disc tissue, blood, saline, and surgical debris can collect around these areas. The Class I classification reflects a reusable manual surgical instrument with mechanical grasping action. CE marking and ISO 13485 documentation support regulated purchasing records for hospitals, surgical centers, and distributors. FDA compliance information supports procurement files for regulated healthcare markets. The one-year warranty, MOQ of one piece, OEM availability, carton box packing, rust-free listing, and return or replacement support fit spine tray replenishment and distributor supply workflows.

How does Peapod Intervertebral Disc Rongeur differ from a Kerrison rongeur?
Peapod Intervertebral Disc Rongeur is designed for grasping and retrieving disc material through angled-up peapod cup jaws. A Kerrison rongeur uses a fixed footplate and sliding punch jaw for removing lamina, ligamentum flavum, and foraminal margins. The Peapod pattern enters the intervertebral space and captures soft fibrocartilaginous fragments for withdrawal. The Kerrison pattern advances beneath a firm bony or ligamentous edge and removes tissue through a punch bite. Peapod Intervertebral Disc Rongeur is selected when the clinical task is disc fragment retrieval rather than spinal bone window enlargement. Both instruments can appear in spine trays, but their tissue targets and working mechanisms are different.

How are the 2.0mm, 2.5mm, 3.0mm, and 4.0mm angled-up variants selected?
The 2.0mm variant is selected for narrow cervical access, limited annular windows, and fine fragment retrieval close to protected neural tissue. The 2.5mm options support controlled retrieval of small disc fragments where precision and cup placement are prioritized. The 3.0mm versions are selected for routine lumbar or cervical disc removal when the annular opening allows a moderate bite. The 4.0mm variants are used when the surgeon needs broader capture of accessible disc material. Peapod Intervertebral Disc Rongeur is also selected by working length, with 5-1/2" patterns supporting compact fields and 7" patterns supporting deeper access. Selection follows disc level, fragment position, annular window size, and exposure depth.

How do CE, ISO 13485, and FDA documentation support procurement?
CE marking supports conformity documentation for hospital purchasing and distributor review. ISO 13485 indicates that the manufacturing system follows medical device quality management and traceability requirements. FDA compliance information supports procurement records for regulated healthcare supply channels. Hospitals, surgical centers, spine teams, and instrument distributors use these documents during vendor approval, tender preparation, and tray standardization. Peapod Intervertebral Disc Rongeur can be entered into purchasing systems with recognized compliance references. This documentation supports international healthcare buyers comparing reusable spinal rongeurs across multiple suppliers.

How is the ring handle and pivot mechanism used intraoperatively?
The ring handles provide controlled finger placement while the shaft is advanced toward the selected disc fragment. During use, the surgeon opens the peapod cup jaws, positions the angled-up distal tip around the target tissue, and compresses the rings to close the working end. The pivot transfers hand movement through the shaft and keeps the cups aligned during capture. After the tissue is secured, the instrument is withdrawn while maintaining grip on the fragment. The rings allow controlled release and repeated repositioning without changing the main hand posture. Peapod Intervertebral Disc Rongeur depends on this pivoted ring-handle action for accurate spinal disc retrieval.

What should operating room teams know about sterilization and ordering?
This instrument is reusable and suitable for standard surgical instrument reprocessing workflows. Cleaning focuses on the cup jaws, distal hinge, shaft channel, pivot recesses, ring handles, and internal closing surfaces before sterilization. The working end is opened, brushed, rinsed, dried, and inspected for alignment before packaging. Steam autoclave processing follows the facility’s approved cycle for reusable stainless steel surgical instruments. Clinics and hospitals can order one piece because the MOQ is one piece. Peapod Intervertebral Disc Rongeur is supplied with OEM availability, one-year warranty coverage, and return or replacement after-sale support.
