In this video, we will discuss the Laparoscopic Maryland Dissector, one of the most versatile and indispensable instruments used in minimal access surgery. Known for its precision and multifunctionality, the Maryland dissector plays a critical role in various laparoscopic procedures by enabling fine dissection, tissue grasping, coagulation, and anatomical plane creation.

Instrument Design and Features

The Maryland dissector is characterized by its slim, curved, and tapered jaws with a slightly pointed tip, making it ideal for both sharp and blunt dissection. It comes with a rotatable shaft, providing greater flexibility and maneuverability within the abdominal cavity, and an ergonomically designed handle for comfortable grip during prolonged surgeries. When connected to a monopolar electrosurgical unit, it also functions as a cutting and coagulating tool, reducing the need to switch instruments.

Surgical Applications Shown in the Video

Laparoscopic cholecystectomy – Dissecting Calot’s triangle and mobilizing the gallbladder
Laparoscopic hysterectomy – Separating uterine ligaments and creating the uterovesical fold
Adhesiolysis – Gently releasing adhesions in pelvic or bowel surgeries
Urologic and colorectal surgeries – Precise dissection near ureters and major vessels
Lymphadenectomy – For careful node clearance while preserving surrounding structures

The video demonstrates live surgical footage and technique tips on how to use the Maryland dissector effectively, including electrosurgical activation and safe dissection strategies.

Advantages of the Maryland Dissector

Combines dissection and coagulation in a single instrument
Provides excellent tactile feedback and control
Reduces instrument exchanges, enhancing surgical efficiency
Ideal for working in confined and delicate anatomical spaces
Enhances patient safety by allowing precise movement around vital structures

Conclusion

The Laparoscopic Maryland Dissector is more than just a dissecting tool—it’s a multi-functional instrument that enhances precision, safety, and efficiency in laparoscopic surgery. As seen in this video, its unique design and adaptability make it a staple in procedures ranging from routine cholecystectomy to complex gynecologic and colorectal surgeries.
