Introduction
In every surgical procedure, removing unwanted, damaged, or diseased tissue is a critical step. The process must be precise, controlled, and safe to protect surrounding healthy structures. Therefore, knowing which surgical instrument is used to remove tissue is essential for every surgical technologist, medical student, and healthcare professional involved in the operating room.
Different instruments are designed to cut, scrape, excise, or suction tissue depending on the nature of the surgery. From delicate soft tissues to hard bone, surgeons rely on specialized tools to achieve clean and efficient removal. In this detailed guide, we’ll explore the most common surgical instruments used to remove tissue, their classifications, uses, and handling techniques — along with SEO-focused structure built around your keyword.
Understanding Tissue Removal in Surgery
“Tissue removal” in surgery refers to the elimination of tissue that is diseased, damaged, infected, or no longer needed. The objective is to restore normal function, remove obstructions, or obtain samples for diagnostic purposes (such as biopsy).
Tissue removal can occur in different forms:
- Excision – complete cutting out of tissue (e.g., tumor removal)
- Scraping or curettage – scraping out tissue or debris
- Debridement – cleaning or removing dead or infected tissue
- Bone removal – trimming or gouging bone fragments
Each method requires a specific instrument designed to perform the job safely and effectively.
Classification of Surgical Instruments for Tissue Removal
Surgical instruments are categorized based on their function. Instruments that remove tissue generally fall under the “cutting and dissecting” category. However, within that category, there are several subtypes:
- Cutting Instruments – Scalpels, scissors, and knives designed to cut through soft or hard tissue.
- Scraping Instruments – Curettes and rasps used to scrape or scoop tissue.
- Excision Instruments – Rongeurs and bone cutters used to excise or remove bone and cartilage.
- Energy-Based Instruments – Devices that use ultrasonic, laser, or electrical energy to remove tissue while sealing vessels.
The Main Instrument Used to Remove Tissue: The Curette
The curette is one of the primary surgical instruments used to remove tissue. It is a hand-held instrument with a spoon-shaped or looped end designed for scraping or scooping out soft tissue, bone, or debris.
Features of a Curette
- Has a long handle for precise control.
- The tip is scoop-shaped, oval, or circular.
- The edge may be sharp or blunt depending on the tissue type.
- Comes in various sizes and curvatures for different surgical sites.
Function of a Curette
A curette removes tissue by scraping rather than cutting. It allows the surgeon to control the depth and pressure of tissue removal. It is especially useful for removing soft tissue in confined spaces where a scalpel or scissors cannot reach easily.
Common Uses of Curettes
- Gynecology – to remove the uterine lining in dilation and curettage (D&C) procedures.
- Orthopedic Surgery – to remove damaged bone or cartilage.
- ENT Surgery – to remove adenoids or other small tissue masses.
- Dermatology – to scrape out skin lesions or cysts.
- Dental Surgery – to remove granulation tissue from tooth sockets after extraction.
Advantages
- Precise and controlled tissue removal.
- Minimal damage to surrounding tissue.
- Useful in delicate or narrow areas.

Other Surgical Instruments Used to Remove Tissue
While the curette is the most direct answer, several other instruments play vital roles in tissue removal, depending on the type of tissue and surgery.
Scalpel
A scalpel is a small, sharp knife used to make incisions or excise tissue. It is the most common cutting tool in surgery.
Uses:
- Making incisions to access tissues.
- Removing small sections of tissue for biopsy.
- Performing precise cuts during delicate surgeries.
Features:
- Consists of a handle and replaceable blades (numbers 10, 11, 15 are most common).
- Allows clean, sharp cuts with minimal tissue trauma.
Tip: Always handle with care and dispose of blades properly in sharps containers.
Surgical Scissors
Scissors are used for cutting and dissecting tissue. Different types are designed for various tissues and functions.
Common Types:
- Mayo Scissors: Heavy, strong scissors used for cutting thick tissues like fascia and muscle.
- Metzenbaum Scissors: Long, slender scissors used for delicate dissection of soft tissue.
- Iris Scissors: Small scissors used for fine or ophthalmic surgery.
Function: Used to excise or trim tissue precisely during dissection or tissue removal.
Rongeur
A rongeur is a heavy-duty instrument designed to remove bone or dense tissue. It works like a pair of pliers with a sharp-edged scoop tip that bites away small pieces of bone.
Uses:
- Neurosurgery (removing bone from the skull or spine)
- Orthopedic surgery (trimming bone fragments)
- Dental surgery (removing bone near tooth sockets)
Tip: Always use in a controlled motion to avoid removing excess bone.
Bone Cutter
Bone cutters resemble rongeurs but are stronger and specifically designed for cutting through thicker or harder bone.
Function: Used in orthopedic, neurosurgical, and thoracic procedures to remove bone segments or ribs.
Types:
- Straight bone cutter
- Double-action bone cutter
- Angled cutter for deeper access
Tip: Use with steady pressure; keep cutting edges sharp.
5. Electrosurgical and Ultrasonic Instruments
Modern surgical advancements have introduced energy-based devices that remove tissue using heat, vibration, or energy.
Examples:
- Electrocautery: Uses electric current to cut and coagulate tissue.
- Harmonic Scalpel: Uses ultrasonic vibration to cut and simultaneously seal small blood vessels.
- Laser Scalpels: Vaporize or remove tissue using focused light energy.
Advantages:
- Reduces bleeding.
- Shortens procedure time.
- Minimizes tissue trauma.
Suction and Aspiration Devices
In procedures like liposuction or certain neurosurgeries, tissue is removed using suction devices.
Example Instruments:
- Yankauer Suction Tip: For clearing blood and fluids.
- Liposuction Cannula: For removing subcutaneous fat tissue.
- Neurosurgical Aspirators: For removing small fragments of soft tissue or tumors.
Choosing the Right Instrument to Remove Tissue
Selecting the correct surgical instrument depends on several key factors:
Type of Tissue
- Soft tissue → Curette, scissors, scalpel
- Bone → Rongeur, bone cutter
- Fibrous tissue → Scissors or rongeur
Surgical Site
The accessibility of the surgical site determines instrument size and shape. Curved or angled instruments help reach deep or narrow areas.
Precision Required
For delicate removal, such as near nerves or blood vessels, finer instruments like a curette or Metzenbaum scissors are preferred.
Surgeon’s Preference
Surgeons often develop personal preferences for instruments based on familiarity and procedural success.
Patient Safety
Instruments should be used only for their designed purpose to prevent tissue damage, infection, or procedural delays.
Maintenance and Care of Tissue Removal Instruments
Proper care and maintenance of surgical instruments are vital for patient safety and instrument longevity.
Cleaning
- Immediately rinse instruments after use to remove blood and debris.
