Study Notes
Instrument Anatomy
- Consists of finger rings, ratchet, shank, box lock, jaws, and tips.
Jaws
- Designed to hold tissue securely, with points that should meet.
- Can be angled at 45 or 90 degrees and may feature various serrations.
Joint/Box Lock
- The cleaning of this part of the clamp is difficult.
Shank
- Length of the shank influences the force applied; located between the joint and finger rings.
Ratchets
- Interlocking components that mesh smoothly, keeping the instrument closed.
- Difficult to clean and are an essential part of surgical instruments.
Tips
- Can be pointed or rounded, affecting their use.
Cutting and Dissecting Instruments
- Sharp-edged instruments are used for incision and tissue excision.
Knife/Scalpel
- Available in various sizes with disposable blades.
- Handles include sizes #3, #3L, #4, #7, compatible with specific blade types.
Scissors
- Utilize multiple types for tissue management, including tissue and suture scissors.
- Specialized scissors include Potts-Smith and Jorgenson models, designed for specific applications.
Grasping and Holding Instruments
- Designed for tissue manipulation, aiding dissection or suturing.
- Must ensure a firm grip with minimal tissue trauma.
Ratcheted Grasping/Holding Instruments
- Common types include Allis, Babcock, Kocher, and Ochsner.
Tissue Forceps
- Also known as pick-ups or thumb forceps, used without ratchets for tissue grasping.
Types of Forceps
- Vary by design: Teeth (for heavy tissue), serrated (for delicate structures), or smooth (for sensitive tissue).
Towel Clips
- Used to hold drapes together; types include Edna (non-penetrating) and Backhaus (penetrating).
Clamping/Occluding Instruments
- Designed to constrict tissue and control blood flow, such as hemostatic clamps.
Anatomy of a Clamp
- Features finger ring handles, interlocking ratchets, shanks connecting to box lock, and atraumatic jaws.
Characteristics of a Clamp
- Can be straight or curved, with serrations that prevent tissue damage during use.
Retracting/Viewing Instruments
- Designed to expose operative sites while protecting underlying tissues.
Types of Retractors
- Include hand-held (sharp rake-like), flat malleable, and self-retaining retractors.
Probing Instruments
- Malleable, wire-like instruments used to explore structures.
Dilating Instruments
- Gradually widen orifices, often found in numbered sets for various specializations.
Suturing
- Involves closing wounds or incisions through stitching or similar methods.
Needle Holders
- Grasp and hold suture needles; types include fine, regular, and heavy based on needle size and tissue type.
Suctioning Instruments
- Remove bodily fluids to improve surgical visibility; types include disposable and non-disposable options.
Endoscopic Instruments
- Used for minimally invasive procedures, varying in size and capabilities, including cautery functions.
Robotic Instruments
- Operated by a pulley system within a robotic arm for precision in minimally invasive surgeries.
Micro-Instruments
- Fine, delicate tools typically washed by hand, needing careful handling and separate storage.
Instrument Handling
- Instruments should only be used as intended; handle gently to avoid damage.
Intra-operative Cleaning
- Requires cleaning instruments with sterile water during procedures to prevent corrosion.
Instrument Care
- Involves thorough inspection before and after use; damaged instruments should be set aside for repair.
Handling Techniques
- Instruments passed to surgeons in functional position; movements should be positive and decisive.
Sharps Handling
- Needles and blades should be secured in holders and disposed of immediately in sharps containers.
Instrument Cleaning
- Begins immediately after use; instruments must be disassembled and cleaned thoroughly.
Decontamination Area
- Use neutral pH detergents; avoid abrasives that could damage instruments.
Reassembly
- Instruments are organized into specialized sets for various surgical specialties.
Counting Instruments
- An initial count occurs before cases begin, ensuring all instruments are accounted for throughout procedures.
