The application of laparoscopic cannulas has extended beyond traditional general surgery and gynecology to urology, thoracic surgery, pediatric surgery, bariatric and metabolic surgery, and other disciplines. Diverse clinical settings impose differentiated requirements on cannula functions, specifications and operational performance, driving products toward specialization and high-precision design.

In general surgery, laparoscopic cholecystectomy, appendectomy and hernia repair remain the mainstream applications for laparoscopic cannulas. These procedures generally require 3 to 5 access ports, with cannulas ranging from 5 mm to 12 mm in diameter being the most widely used. In recent years, the growing adoption of Laparo-Endoscopic Single-Site Surgery (LESS) for cholecystectomy and other operations has fueled robust market growth of multi-channel single-port trocars - devices that allow multiple instruments to pass through a single 15–25 mm cannula. Such products deliver superior cosmetic outcomes and less postoperative pain, yet they pose higher technical challenges, mainly including instrument collision and loss of the surgical triangulation.

Gynecological laparoscopic surgery constitutes another major market, covering hysterectomy, ovarian cyst resection and infertility treatment. Gynecological procedures demand extremely high puncture precision and safety to avoid injuries to pelvic blood vessels, the uterus and intestines. Accordingly, cannulas fitted with visual tips or optical puncture systems are widely favored in this field. Meanwhile, dedicated instruments for vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) are under development to further reduce external bodily trauma.

Urological procedures such as laparoscopic radical prostatectomy and partial nephrectomy set strict standards for puncture accuracy and cannula stability. Given the frequent replacement of instruments with varying angles and functions during operations, cannulas equipped with multiple sealing valves, excellent airtight performance and quick instrument exchange capabilities gain distinct advantages. Additionally, pediatric laparoscopic surgery requires smaller-diameter cannulas (e.g., 3 mm) due to children's compact anatomical structures and limited operative space, with more stringent standards for trauma control.

Emerging fields including bariatric and metabolic surgery (such as sleeve gastrectomy) and robot-assisted laparoscopy have become new growth drivers for cannulas. Cannulas used in bariatric surgery need enhanced durability to penetrate thick abdominal walls. For robotic surgery, cannulas must achieve perfect compatibility with robotic instrument interfaces to ensure precise movement transmission of robotic arms.

Going forward, alongside advances in surgical techniques and evolving disease treatment paradigms, laparoscopic cannulas will continue to develop toward minimal invasiveness, intelligence and deeper specialization. Manufacturers need to closely follow updates on clinical surgical approaches and collaborate extensively with surgeons to develop innovative products that address unmet clinical needs.
