Trocar Cannula System

Trocar Cannula System is a specialized ophthalmic surgical access system used during pars plana vitrectomy (PPV) and other vitreoretinal procedures to establish minimally invasive entry ports into the eye. The system typically consists of a sharp trocar blade or obturator housed within a precision-engineered cannula sleeve . During insertion, the trocar creates a controlled scleral entry pathway, and once positioned, the trocar is removed, leaving the cannula in place as a stable access port for surgical instruments. Designed for modern microincision vitreoretinal surgery (MIVS), the Trocar Cannula System facilitates repeated instrument exchanges while helping maintain intraocular pressure and minimizing trauma to surrounding tissues. The cannula serves as a protected pathway for vitreoretinal instruments such as vitrectomy probes, illumination probes, infusion cannulas, membrane peeling forceps, laser probes, scissors, and aspiration instruments. This allows efficient surgical workflow while preserving the integrity of the scleral incision. The low-profile design supports self-sealing wound architecture and contributes to reduced tissue disruption compared with traditional larger-gauge surgical approaches. The system helps maintain a stable surgical environment throughout the procedure. Trocar Cannula Systems are routinely used during retinal detachment repair, pars plana vitrectomy, diabetic vitreoretinal surgery, macular surgery, membrane peeling procedures, vitreous hemorrhage management, endolaser treatment, and posterior segment reconstruction. Manufactured from high-quality surgical-grade materials, the system provides dependable performance, precise fit, and secure instrument passage. Depending on the configuration, systems may be supplied as sterile single-use devices or reusable components. Available in multiple gauge sizes, including microincision vitreoretinal surgery platforms, Trocar Cannula Systems can be selected according to surgical technique and surgeon preference. Widely used in hospitals, ophthalmic surgery centers, retinal specialty clinics, and ambulatory surgical facilities, the Trocar Cannula System is a fundamental component of modern vitreoretinal surgery.
