What Is a Trocar? Types of Laparoscopic Trocars & Selection Guide
What Is a Trocar in Laparoscopic Surgery? Types, Functions, and Selection Guide
This article explains what a trocar is, common laparoscopic trocar types, typical sizes, and key selection considerations for minimally invasive surgery workflows. Content is written for B2B procurement, OEM/ODM sourcing, and clinical engineering reference.
What Is a Trocar in Laparoscopic Surgery?
A trocar is a surgical access device used in laparoscopic and minimally invasive surgery (MIS) to establish a controlled entry point through the abdominal wall. Once inserted, the trocar allows laparoscopic instruments and endoscopes to pass into the surgical cavity while maintaining a stable access channel.
In modern operating rooms, trocars are considered a foundational component of laparoscopic access systems, supporting consistent instrument entry and workflow standardization.
What Is a Trocar Used For?
In laparoscopic procedures, trocars are used to:
- Establish an access path for laparoscopic instruments
- Support repeated instrument insertion and removal
- Help maintain pneumoperitoneum during procedures
- Integrate with standard minimally invasive surgical setups
Trocars are commonly used across general laparoscopic surgery, gynecological procedures, urological laparoscopy, and other MIS workflows.
Types of Laparoscopic Trocars
There are several commonly used types of laparoscopic trocars, each designed to support different access preferences and procedural requirements.
1) Classic Trocars
Classic trocars feature a traditional design and are widely used for routine laparoscopic access. They often incorporate integrated valve systems to support air leakage control during instrument exchange.
2) Bladeless Trocars
Bladeless trocars are designed to separate tissue rather than cut, supporting controlled insertion during access establishment. They are commonly selected for procedures prioritizing tissue separation techniques.
3) Optical Trocars
Optical trocars allow visualization during insertion by accommodating laparoscopic scopes. This type supports visual confirmation of tissue layers during access placement.
Common Trocar Sizes and Configurations
Laparoscopic trocars are typically available in standardized diameters to accommodate common instruments:
- 5 mm – for smaller laparoscopic instruments
- 10 mm – for cameras and medium-sized tools
- 12 mm – for larger instruments and specimen-related access
Standard lengths (such as 100 mm) are commonly used to support abdominal access in minimally invasive surgery.
Single-Use vs Reusable Trocars
Many modern laparoscopic trocars are designed as single-use devices to support infection control protocols and operating room hygiene standards. Disposable trocars are often EO sterilized and supplied ready for use, simplifying reprocessing requirements.
Reusable trocars may still be used in some settings but typically require validated cleaning and sterilization workflows.
How to Choose the Right Trocar
When selecting laparoscopic trocars, buyers and clinical engineers typically consider:
- Intended procedure type
- Instrument diameter compatibility
- Valve system design and air leakage control
- Single-use or reusable configuration
- Regulatory compliance requirements
- OEM or private labeling availability
Choosing the appropriate trocar supports smoother integration into existing laparoscopic workflows and procurement systems.
Trocar Devices in OEM and Global Supply Chains
For medical device manufacturers and distributors, trocars are frequently sourced through OEM or ODM programs. Key considerations include regulatory certification, production consistency, SKU management, and compatibility with global procurement standards.
Frequently Asked Questions About Laparoscopic Trocars
What is the main function of a trocar?
A trocar is used to establish an access path for laparoscopic instruments and endoscopes during minimally invasive surgery.
What are the most common types of laparoscopic trocars?
The most common types of laparoscopic trocars include classic trocars, bladeless trocars, and optical trocars.
Are laparoscopic trocars single-use or reusable?
Both single-use and reusable laparoscopic trocars are available, although many modern devices are designed as single-use to support infection control practices.
What trocar sizes are commonly used?
Common trocar sizes include 5 mm, 10 mm, and 12 mm, depending on the laparoscopic instruments used.
Can trocars be supplied through OEM programs?
Yes, laparoscopic trocars are commonly supplied through OEM or private labeling programs for global medical device markets.
