Disposable Laparoscopic Trocar (Metal)

Disposable Laparoscopic Metal Trocar Product Overview

The Disposable Laparoscopic Metal Trocar is a sterile, single-use access device designed for laparoscopic and thoracoscopic procedures. Manufactured with a durable metal needle bar, it provides consistent puncture strength and reliable access performance. The air-tight sealing system helps maintain pneumoperitoneum, while the visual lens supports controlled trocar insertion. The inverted-tooth cannula design helps minimize slipping during use. Available in 5 mm, 10 mm, 12 mm, and 15 mm diameters, the system is suitable for different laparoscopic instruments and procedural requirements. Each set includes a puncture needle and cannula, supplied sterile and ready for clinical use.

Disposable Laparoscopic Metal Trocar Use Cases

Used in laparoscopic surgery to puncture the abdominal wall and establish a working access channel for abdominal procedures.

Key Advantages

The Disposable Laparoscopic Trocar (Metal) offers a range of distinct clinical benefits that enhance surgical safety, efficiency, and patient outcomes.

Unique Air-Tight Seal Design – The trocar features an advanced air-tight sealing system that effectively prevents gas leakage during pneumoperitoneum maintenance. This ensures consistent intra-abdominal pressure throughout the procedure, providing optimal surgical visibility and working space while reducing the need for repeated insufflation adjustments.

Puncture Visual Lens Design – The innovative visual lens design allows for clear visualization during insertion, significantly reducing the risk of inadvertent organ or vessel puncture. This safety feature enables surgeons to confirm proper positioning before advancing the trocar, minimizing complications associated with blind puncture techniques.

Inverted Tooth Tube Body – The tube body incorporates an inverted tooth design that prevents the cannula from slipping or being inadvertently dislodged once positioned. This feature ensures stable, reliable instrument access throughout the entire procedure, reducing the risk of accidental withdrawal and the need for re-insertion.

Durable Metal Needle Bar Construction – The metal needle bar provides exceptional strength and precision for abdominal wall puncture, enabling smooth, controlled insertion through the abdominal wall. The metal construction ensures consistent performance and reduces the risk of needle deformation or breakage during insertion.

Multiple Diameter Options – Available in 5 mm, 10 mm, 12 mm, and 15 mm diameters, the system accommodates a wide range of instrument sizes, from diagnostic scopes to larger surgical instruments. This comprehensive sizing matrix ensures the appropriate trocar is available for every procedure, reducing the need for multiple trocar types.

Metal and Plastic Needle Bar Options – The system offers both metal needle bar (ZCJB series) and plastic needle bar (ZCJC series) configurations, allowing surgeons to choose the needle type that best suits their clinical preference and specific procedural requirements.

Disposable Sterile Design – Supplied sterile and intended for single use, the trocar eliminates the risk of cross-contamination associated with reusable devices. The sterile packaging ensures optimal safety and performance with every procedure.

Technical Specifications & Sizing

Size Range Overview

The Disposable Laparoscopic Trocar (Metal) System offers four diameter options to accommodate a wide range of surgical instrument sizes.

Detailed Dimension Table

Note: All trocars are supplied sterile, single-use, and individually packaged. The ZCJB series features a metal needle bar for enhanced durability and puncture precision, while the ZCJC series features a plastic needle bar for applications where a lighter, non-metallic option is preferred. The puncture set includes both the puncture needle and the cannula with sealing mechanism. The diameter refers to the outer diameter of the cannula and corresponds to the maximum instrument size that can be accommodated.

RFQ – Request for Quotation

Q1: What is the difference between the metal needle bar (ZCJB) and plastic needle bar (ZCJC) trocars?
A: The ZCJB series features a metal needle bar that provides enhanced durability and precision during abdominal wall puncture. The metal construction ensures consistent performance and reduces the risk of needle deformation or breakage during insertion, making it ideal for patients with thicker abdominal walls or denser tissues. The ZCJC series features a plastic needle bar that offers a lighter, non-metallic option suitable for standard procedures where a metal tip is not required. Both series feature the same air-tight seal design, visual lens safety feature, and inverted tooth tube body. The choice between metal and plastic needle bars should be based on surgeon preference and specific procedural requirements.

Q2: How does the air-tight seal design prevent gas leakage during surgery?
A: The trocar incorporates an advanced sealing mechanism at the cannula entry point that maintains pneumatic integrity throughout the procedure. This design effectively prevents gas leakage during pneumoperitoneum maintenance, ensuring consistent intra-abdominal pressure and optimal surgical visibility. The seal is designed to accommodate instrument insertion and removal while maintaining a gas-tight closure when no instrument is present. This feature significantly reduces the need for repeated insufflation adjustments and helps maintain a stable surgical environment.

Q3: What is the puncture visual lens design, and how does it improve safety?
A: The puncture visual lens design incorporates an optical element that allows the surgeon to visualize the tissue layers during trocar insertion. This enables clear visualization of the puncture trajectory, significantly reducing the risk of inadvertent organ or vessel puncture. The visual lens enables surgeons to confirm proper positioning before advancing the trocar through the abdominal wall, minimizing the complications associated with blind puncture techniques. This safety feature is particularly valuable in patients with previous abdominal surgery where adhesions may be present.

Q4: What is the function of the inverted tooth tube body design?
A: The inverted tooth tube body incorporates a textured pattern that creates friction against the abdominal wall tissues once the cannula is positioned. This design prevents the cannula from slipping or being inadvertently dislodged during instrument exchanges or manipulation. The secure positioning ensures stable, reliable instrument access throughout the entire procedure, reducing the risk of accidental withdrawal and the need for re-insertion. This feature also helps maintain the integrity of the pneumoperitoneum by preventing gas leakage around the cannula.

Q5: What are the recommended trocar sizes for different surgical instruments?
A: The 5 mm trocar is suitable for diagnostic laparoscopy, biopsy instruments, and smaller graspers. The 10 mm trocar is suitable for most standard laparoscopic instruments, including graspers, scissors, and 10 mm laparoscopes. The 12 mm trocar accommodates larger instruments, including 12 mm staplers and larger graspers. The 15 mm trocar is suitable for specimen retrieval, morcellation devices, and larger surgical instruments. We recommend selecting the smallest trocar that will accommodate the largest instrument planned for use through that port.

Q6: What is the standard packaging configuration and shelf life for the trocars?
A: The Disposable Laparoscopic Trocars are individually packaged in sterile blister packs and are supplied sterile, single-use. The typical shelf life is 3–5 years from the date of manufacture, as indicated on the product labeling. They should be stored in a cool, dry environment away from direct sunlight and extreme temperatures. The sterile packaging should remain intact until the time of use to ensure sterility. We recommend checking the expiration date before use and disposing of any expired or damaged products.
