Detailed information about Laparoscopic Instruments | Laparoscopic Instrument Names and their Uses

Detailed information about Laparoscopic Instruments | laparoscopic instrument names and their uses Today, we’ll discuss routine laparoscopic instruments. We won’t include special instruments, such as those used in gynecology, coagulation instruments, or advanced tools. This discussion focuses solely on routine laparoscopic instruments typically used in standard laparoscopic surgeries. For example, the instrument we’re showcasing here is a bit longer and is usually employed in bariatric surgeries or for patients with obesity. The standard instrument length is typically used in routine surgeries, while shorter ones are for pediatric cases, and longer ones for specialized needs like bariatric procedures. The length of a laparoscopic instrument is measured by the shaft, typically ranging between 33–37 cm for routine instruments, less than 30 cm for pediatric instruments, and more than 40 cm for longer instruments. For example, this instrument here measures about 42 cm, and some can extend up to 45 cm. The width of instruments also varies: routine laparoscopic instruments are typically 5 mm, while mini laparoscopic or pediatric instruments are around 3 mm or less. Now, let’s explore the parts of a laparoscopic instrument. Once disassembled, you’ll find three main components: The handle The insulated outer sheath (black in color) – protects adjacent organs by preventing the spread of electrical current. The insert – has a specific tip designed for various functions. Important Features: Insert: This is the working tip that performs the intended task (e.g., dissection, grasping). Sheath: The metallic section conducts electricity, while the insulated part shields against accidental current spread. When assembling: Insert the tip into the sheath (this is why it’s called the "insert"). Connect the handle, ensuring it locks securely. Attach the monopolar cable (for monopolar instruments). The handle often features a rotation mechanism for precise angular control during procedures. Disassembly for cleaning is essential for proper sterilization: disengage the components completely to clean inner parts effectively. Tip: Always check the insulation sheath for damage before and after each use. If the insulation is compromised, replace the sheath while reusing the handle and insert. Types of Laparoscopic Instrument Tips: Bowel Grasper: Broad, perforated tips designed for holding bowel tissue with minimal trauma. Gentle handling reduces tissue damage. Routine Grasper: Used for holding tissue, typically with the left hand. Features blunt tips to minimize injury during insertion. Maryland Dissector: A curved dissector with a tapered, blunt tip. Versatile for dissection and suturing, commonly used in the surgeon's right hand. BCX Forceps: Features a hollow space for holding tissue securely without crushing it. Ideal for handling delicate structures. Tooth Forceps: Equipped with sharp teeth for gripping tougher tissues or specimens. Often used for secure retraction during surgeries like cholecystectomy. Laparoscopic Scissors: Curved scissors for cutting tissue or sutures. Hooked scissors are specifically designed for suture cutting, preventing slippage. Hook Electrode: Features a hook-shaped tip for fine dissection and coagulation. The tip and elbow provide precision and broader coagulation coverage. Spatula Electrode: A flat, broad tip for coagulation and dissection. Its ceramic insulation prevents overheating and prolongs the instrument’s lifespan. Monopolar vs. Bipolar Instruments Monopolar Instruments: Single electrode at the tip. Requires a patient pad to complete the electrical circuit through the body. Bipolar Instruments: Two electrodes located on the instrument’s jaws. Current passes only through the tissue held between the jaws, making it safer for patients, especially those with pacemakers. Advanced Bipolar Devices (e.g., LigaSure): Intelligent systems that adjust current based on tissue resistance. Provide audible feedback once coagulation is complete. Capable of coagulating vessels up to 7 mm in diameter. Include cutting mechanisms for precise dissection and hemostasis. We hope this discussion on routine laparoscopic instruments was helpful.
