Descripción
The XISHAN Disposable Trocar Series provides safe, reliable, and gas-tight optical access into the peritoneal and thoracic cavities for minimally invasive surgery (MIS). Engineered specifically for laparoscopic general surgery, gynecology, urology, and thoracic procedures, it establishes a stable operative channel for rigid endoscopes, ultrasonic soft tissue scalpels, endoscopic staplers, and grasping instruments.
Featuring advanced dual-layer sealing valve technology and an optical dilating obturator tip, XISHAN trocars maintain consistent pneumoperitoneum pressure under continuous CO₂ insufflation while minimizing abdominal wall trauma, bleeding, and the risk of post-operative incisional herniation.
Key Sealing & Structural Innovations
Dual-Seal Gas-Tight Valve
Integrated elastomeric duckbill seal and flexible universal iris gasket prevent CO₂ leakage during rapid instrument exchange (5mm to 12mm) and multi-angle manipulation.
Optical Dilating Bladeless Tip
Transparent optical tip enables direct visualization of abdominal tissue layers during entry under 0°/30° endoscopes, gently separating muscle fibers without sharp cutting.
Threaded Fixation Sleeve
Precision retention threads along the cannula ensure secure anchoring in the abdominal wall, preventing accidental sleeve dislodgement or slippage during high-frequency instrument passes.
Detachable Modular Seal Cap
Quick-release upper housing permits instant seal removal for rapid, snag-free extraction of large resected specimens, organ tissue, or endo-retrieval bags.
Integrated Insufflation & Smoke Evacuation
- Dedicated Luer-Lock Stopcock: Integrated one-way stopcock valve connects seamlessly with standard CO₂ insufflation tubing for rapid cavity distension and controlled pressure regulation.
- Smooth Low-Friction Inner Bore: Specially treated cannula inner surface reduces instrument dragging resistance, providing tactile feedback for delicate dissections.
- Low-Profile Ergonomic Housing: Compact outer profile maximizes ergonomic clearance in crowded multi-port surgical setups.
Clinical Applications
- General & Gastrointestinal Surgery: Laparoscopic cholecystectomy, appendectomy, inguinal / ventral hernia repair, colorectal resection, and sleeve gastrectomy.
- Gynecological Laparoscopy: Laparoscopic total hysterectomy (TLH), ovarian cystectomy, myomectomy, and pelvic lymph node dissection.
- Urological Laparoscopy: Laparoscopic radical prostatectomy (LRP), partial / radical nephrectomy, pyeloplasty, and adrenalectomy.
- Video-Assisted Thoracoscopic Surgery (VATS): Thoracic cavity port establishment for wedge resection and pleural biopsy.
