Basic Surgical Instruments

Summary

This video provides surgical technology students with an essential introduction to around 50 commonly used surgical instruments. Covering a range of tools—from electrosurgical units, harmonic scalpels, clamps, scissors, scalpels, and forceps to retractors, suction tips, and needle holders—the instructor explains their specific functions, variations, and applications. Key distinctions, such as curved versus straight, atraumatic versus traumatic, and handle or tip design, are emphasized to help students understand proper usage. The overview equips learners with foundational knowledge for identifying, handling, and using these instruments safely and effectively during surgical procedures, laying the groundwork for mastering more advanced tools.

Takeaways

• 😀 Surgical technology students must learn hundreds of surgical instruments, but the script focuses on the 50 most basic ones commonly used in many surgeries.
• 🔌 The electrosurgical unit (ESU), or Bovie, is a key instrument that uses electrical currents to cut tissue and coagulate blood vessels, preventing bleeding during surgery.
• ⚙️ There are various types of clamps, such as the mosquito (smallest), Kelly, Pean, and Rochester Pean, each with specific functions in controlling bleeding and holding tissues.
• ✂️ Scissors like Mayo, Metzenbaum, and Lister scissors are designed for cutting tissue, dressings, and sutures, with curved versions improving visibility in small surgical openings.
• 🔪 Scalpel handles (e.g., No. 3, 4, and 7) work with various blades (e.g., No. 10, 11, 12, 15) for precise cuts, with the No. 4 handle designed for larger blades like the No. 20.
• 🖊️ Beaver blades and handles are used for delicate surgeries, like plastic surgery, offering precision and control for fine cuts.
• 🛠️ Forceps (like Adson, DeBakey, and Bonney) come in various types, designed for delicate or tougher tissues and used for grasping or manipulating tissues during surgery.
• 🧼 Towel clamps, such as Backhaus and Roeder, are essential for securing drapes around the surgical site, with some penetrating through the material while others are non-penetrating.
• 🔎 Retractors, such as Army Navy, Parker, Goulet, and Joseph skin hooks, help surgeons keep tissue out of the way to access the surgical site, with both handheld and self-retaining options available.
• 💧 Suction devices like the Fraser suction tip and Yankauer are crucial for removing fluids (blood, irrigation) from the surgical area, ensuring visibility during the procedure.
• 🔩 Needle holders, including the Mayo Hagar, Kelly Wood, and Webster types, are used to hold suturing needles and assist in stitching tissues during surgery, with different types for delicate or heavy-duty tasks.

Q & A

What is the primary purpose of an electrosurgical unit (Bovi) in surgery?

The electrosurgical unit is used to cut or coagulate tissue using electrical energy. It can vaporize tissue to cut or heat proteins to coagulate, sealing blood vessels and controlling bleeding.

How does a harmonic scalpel differ from an electrosurgical unit?

The harmonic scalpel uses ultrasonic vibrations to cut and coagulate tissue, creating heat through friction, whereas the electrosurgical unit uses electrical current directly to achieve cutting or coagulation.

What is the difference between a mosquito clamp and a Crile (Cryol) clamp?

A mosquito clamp is smaller and often used for delicate tissue or suture, while a Crile clamp is slightly larger, with serrations that extend fully to the box lock, commonly used to clamp blood vessels.

Why are curved and straight Mayo scissors both used in surgery?

Curved Mayo scissors allow better visibility and control when cutting tissue within small openings, while straight Mayo scissors are primarily used for cutting dressings or sutures.

Which scalpel handles and blades are compatible with each other?

Number 3, 3 long, and 7 handles are compatible with 10, 11, 12, and 15 blades. Number 4 handles are larger and compatible with 20 series blades (20, 21, 22, 25).

What is the purpose of atraumatic versus traumatic clamps?

Atraumatic clamps, like Babcock, are used to handle delicate tissue without causing damage, whereas traumatic clamps, like Allis, provide a strong grip for removing tougher tissue or tissue being excised.

How do self-retaining retractors like the Weitlander differ from handheld retractors?

Self-retaining retractors lock in place to keep the surgical site open without continuous manual holding, while handheld retractors require a surgical assistant to maintain tension during the procedure.

What types of suction devices are mentioned and what are their specific uses?

Fraser suction tip is used for targeted fluid removal and has a stylet for cleaning; Yankauer suction is versatile for general suctioning and protects tissue; Poole suction has multiple holes to safely remove pooled fluids in cavities like the abdomen.

What are the differences between various needle holders such as Mayo-Hegar, Kellywood, Ryder, and Webster?

Mayo-Hegar is heavy-duty for larger needles and tough tissue; Kellywood is fine-tipped for delicate suturing; Ryder has a narrow tip for small needles; Webster is the smallest for very delicate or precise suturing.

Why is it important to distinguish between sharp and dull Senn retractors?

Sharp Senn retractors can easily damage gloves, gowns, or tissue due to their pointed tips. Dull retractors are safer for general use, and unless specified by the surgeon, dull is the preferred choice.

What is the significance of the serration patterns in clamps like Kelly versus Crile?

The serration pattern determines the gripping area: Crile clamps have serrations extending to the box lock for full-length grip, while Kelly clamps have serrations only halfway, allowing for more precise control on specific tissue or vessel size.
