Standard Trocar and Cannula w/stop cock 4.0mm

Clinical Application

This small-bore trocar and cannula assembly establishes a sealed percutaneous access port for minimally invasive procedures where a 4.0 mm conduit is required. The system permits passage of endoscopic instruments, guidewires, and fluid lines while enabling controlled insufflation or irrigation through the integrated stop cock. Common applications include small-joint arthroscopy, endoscopic accessory ports, and other procedures that benefit from a low-profile, sealed access site.

Design & Configuration

The two-component design separates the obturator (trocar) from the cannula so the trocar can create the initial tract while the cannula remains as the working channel. The incorporated stop cock provides a secure, operator-controlled port for insufflation, irrigation, or attachment of tubing while minimizing gas or fluid leakage. The 4.0 mm diameter reduces incision size and soft-tissue trauma compared with larger ports, and the low-profile cannula facilitates instrument manipulation in confined spaces.

Instrument Specifications

• Device type: trocar (obturator) and cannula assembly
• Port diameter: 4.0 mm
• Configuration: removable trocar with cannula; integrated stop cock for controlled flow and sealing
• Typical use: access, instrument passage, insufflation/irrigation control in minimally invasive procedures
• Reusable construction

Material & Construction

Constructed for repeated clinical use with durable, corrosion-resistant stainless steel components. The simple two-piece geometry supports reliable insertion, removal, and reprocessing while the stop cock uses a sealing mechanism to maintain insufflation and control fluid pathways.

Quality & Compliance

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

Brand Comparison
