Disposable Puncture Suturing Device | Dual-Function Puncture and Suturing, Effortless Puncture, Perfect Closure

Laparoscopic surgery, as a minimally invasive technique, has been widely adopted in general surgery for various procedures. During laparoscopic surgery, surgical instruments access the abdominal cavity through trocars. After the procedure, puncture sites remain on the abdominal wall. Improper suturing of these sites can lead to complications such as bleeding, hematoma, infection, and trocar site herniation. Suturing the fascial layer of the puncture site effectively reduces the difficulty of incision closure in laparoscopic surgery, minimizes the risk of trocar site hernia, and enhances surgical safety.

Trocars provide access for endoscopic instruments during laparoscopic surgery. A trocar with integrated suturing capability combines fascial closure functionality into the device, enabling both puncture and suturing in a single step. The disposable puncture suturing device consists of a cannula with a guide hole, a visual obturator, a suturing puncture needle with a side hole, and an abdominal wall puncture needle clamp for grasping the suture. The guide hole on the cannula is sealed with an ultra-thin silicone membrane to prevent air leakage during use.

Product Advantages

Combines dual functions of puncture and suturing, eliminating the need for a separate fascial closure device—offering both medical and economic value.

• Precise Visual Puncture: Significantly reduces the risk of organ injury.

• Simplified Workflow: Easy to master with minimal training, ensuring efficient operation.

• Time-Saving Technology: Rapid suturing enhances procedural efficiency.

• Clear Visual Suturing: The suturing process is fully visible, ensuring accuracy and avoiding organ damage.

• Broad Compatibility: The obturator is compatible with various commercially available cannulas—bladed or bladeless, disposable or reusable.

Strong Market Demand

Data indicates a substantial and steadily growing market demand for laparoscopic trocars. In 2019, sales of disposable trocars in China reached 18.4 million units, with a market value of RMB 1.77 billion. By 2024, this is projected to grow to RMB 5.091 billion, reflecting a compound annual growth rate (CAGR) of 23.4%.

Amid the trend of declining prices due to centralized medical procurement, conventional laparoscopic trocars are losing their competitive edge. In contrast, laparoscopic trocars with fascial closure functionality demonstrate significant clinical advantages. Their innovative design integrates both puncture access and fascial closure, aligning with the market's demand for advanced medical devices.
