Kirschner Wire Tro. point round end 2.2x140mm

Clinical Application

This instrument is a K-wire designed for percutaneous skeletal fixation and temporary stabilization of bone fragments during orthopedic procedures. The 2.2 mm diameter and 140 mm length make it suitable for a wide range of extremity applications including hand, wrist, forearm, foot and toe pinning, as well as certain pediatric and trauma cases where a low-profile, rigid pin is required to maintain reduction or provide provisional fixation prior to definitive fixation.

Design & Configuration

The trocar point configuration provides a sharp, cutting tip for controlled percutaneous entry through soft tissue and cortical bone, minimizing the need for excessive force and reducing skiving off the cortex. A 2.2 mm diameter offers a balance of bending resistance and minimal implant footprint, while the 140 mm length allows passage across common small- and medium-sized bones or through soft-tissue envelopes encountered in extremity procedures. The round-end finish noted in the designation refers to the finished wire end geometry used for handling and seating.

Instrument Specifications

• Instrument type: Kirschner wire (K-wire)
• Model / pattern: Trocar point, round end
• Size: 2.2 x 140 mm (2.2 mm diameter × 140 mm length)
• Tip: Trocar point for percutaneous penetration

• Material: Surgical-grade stainless steel

Material & Construction

Manufactured from surgical-grade stainless steel to provide the torsional strength and straightness required for accurate placement and resistance to bending during use. The wire is produced with a smooth surface finish to reduce tissue drag during insertion and to facilitate radiographic visualization without additional coatings.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.
