Jarit 290-150 Inge Lamina Spreader w/ Teeth 11mm 10-1/4"

Jarit Inge Lamina Spreader | Toothed Jaws | 10-1/4" Length | 290-150

The Jarit 290-150 is a heavy-duty, self-retaining distraction instrument engineered for the high-torque requirements of spinal and orthopedic surgery. Specifically designed for laminectomies and discectomies, the Inge Lamina Spreader allows surgeons to achieve controlled, powerful separation of the vertebral bodies or lamina.

At 10-1/4 inches (260mm) in length, this instrument provides the necessary mechanical leverage to overcome the resistance of dense spinal ligaments and musculature. The 11mm toothed jaws are a critical safety feature, ensuring that once the spreader is engaged, it maintains a non-slip grip on the bony surfaces of the lamina, preventing accidental closure or slippage during delicate neural decompression.

Key Specifications

• Manufacturer: Jarit (Integra LifeSciences)

• Reference Number: 290-150

• Instrument Type: Inge Lamina Spreader

• Material: High-Grade Surgical Stainless Steel

• Overall Length: 10-1/4" (260 mm)

• Jaw Width: 11 mm

• Jaw Feature: Toothed (Fenestrated/Gerrated for grip)

• Mechanism: Integrated Ratchet Lock with Spring-Loaded Return

• Finish: Polished Stainless Steel

Technical & Clinical Advantages

• High-Leverage Distraction: The extended handle length acts as a force multiplier, allowing the surgeon to distract the intervertebral space with minimal physical effort. This is essential for providing adequate visualization of the spinal canal and nerve roots.

• Non-Slip Toothed Jaws: The 11mm jaws feature sharp, precision-milled teeth that "bite" into the cortical bone of the lamina. This provides a secure anchor point, ensuring the instrument does not shift even under significant spring-back pressure from the spinal column.

• Ratcheting Precision: The incremental ratchet mechanism allows the surgeon to open the spreader to a precise width and lock it in place. This "set-and-forget" capability allows the surgeon to work with both hands while the surgical corridor remains wide and stable.

• Curved Arm Ergonomics: The arms are subtly curved to provide a clear line of sight into the distracted space. The design ensures the handles remain outside the primary operative field, reducing obstruction for microscopes or loupes.

• Surgical Grade Durability: Constructed from heavy-gauge stainless steel, the 290-150 is designed to withstand the repeated high-pressure cycles of orthopedic distraction without bending or mechanical fatigue.

Applications

• Spine Surgery: Distraction of the lamina during laminectomies to access the spinal canal; vertebral body separation during discectomies.

• Orthopedic Trauma: Spreading and stabilizing bone fragments during the reduction of large-bone fractures.

• Joint Reconstruction: Maintaining joint space during total knee or hip revisions where dense scar tissue or ligaments must be moved.

Condition & Quality Assurance

• Status: Excellent Pre-owned Condition.

• Integrity: The ratchet mechanism provides crisp, secure engagement across all teeth, and the spring tension is optimal for a controlled return. All teeth on the jaws are sharp and free of blunting.

• Maintenance Requirement: As a reusable stainless steel instrument, this spreader must undergo a validated decontamination and sterilization cycle (standard steam autoclave) according to hospital protocols and Jarit’s Instructions for Use (IFU) before clinical use in 2026.

• Professional Standards: With over 25 years of experience in surgical hardware, Primis Medical ensures all orthopedic distraction tools are inspected for structural alignment and mechanical reliability.

Shipping & Handling

• Secure Logistics: Shipped in heavy-duty protective packaging to ensure the ratchet alignment and jaw integrity are preserved during transit.

• Fast Dispatch: Ships within 1 business day.
