Surgical Instruments and Suture Review Flashcards
Identify this instrument.
Jacob’s Chuck
- Used to drive IM pins and K-wires during orthopedic surgery
- Key used to tighten or release pin grip
- May have attachment for protecting surgeon’s hands from pin penetration near top of handle
Identify this instrument.
Straight Mayo Dissecting Scissors
- Plain edge (vs. serrated edge)
- Thick blades (~1/3 of instrument length)
- Used to incise dense tissue (fascia, linea alba, trimming skin)
- Blades can be straight or curved
- Straight blade: greater mechanical advantage
- Curved blade: improved visualization of tissue, more versatile
Is polypropylene an absorbable or non-absorbable suture material?
non-absorbable
These suture properties are ideal for use in infected tissues:
absorbable and monofilament
These are small, specialized tissue forceps used for ophthalmic surgery:
Bishop-Harmon Tissue Forceps
This antibiotic can be added to a suture coating to help prevent bacterial growth in a surgical wound:
Triclosan
Identify this instrument.
Babcock Tissue Forceps
- Smooth flat tips are used to grasp tissue
- Grasps tissue at right angles of tension application
- Tips can crush but are less traumatic than Allis tissue forceps
- Used for helping to grasp and retract robust soft tissues (stomach, bladder)
When is silk suture used?
Cardiovascular surgery
Is chromic gut an absorbable or non-absorbable suture material?
Absorbable
This refers to a suture’s ability to resist deformation or breakage:
tensile strength
Self-inflicted injuries can occur when using this instrument to drive Steinman pins:
Jacob’s chuck
T/F: Nylon suture is very resistant to degradation due to its lack of hydrolyzable bonds
False
Nylon is susceptible to degradation. Hydration may lead to disruption of hydrogen bonds leading to loss of tensile strength.
This hemostat has multiple uses including occlusion of small vessels and securing stay sutures:
Mosquito hemostats
This suture is rarely used due to the severe inflammatory reaction it can cause:
catgut
Identify this instrument
Backhaus Towel Clamp
- Penetrating clamp
- Used to hold quarter drapes or Huck towels securely to patient skin
Identify this instrument.
Straight Metzenbaum Scissors
- Plain edge (vs. serrated edge)
- Thin, delicate blades (~1/4 of length of instrument)
- Used to incise soft tissues (subcutaneous tissues, intestine, bladder, etc)
- Blades can be straight or curved
- Straight blade: greater mechanical advantage
- Curved blade: improved visualization of tissue, more versatile
This type of monofilament suture has many uses including closure of enterotomies, cystotomies, and many other –otomies:
polydioxanone
Identify this instrument
Extraction Forceps
- Strong, heavy instrument used to grasp loose/luxated teeth for extraction
- Various sizes and tips to accommodate different shaped teeth
Identify this instrument
Dental Explorer
- Increases tactile sensation for detecting areas of enamel decay
When is polymerized caprolactam suture used?
Skin sutures ONLY
Not recommended for implantation in tissues due to sinus formation
Because of rapid loss in tensile strength, this suture type should not be used for slower healing tissues:
polyglycolic acid or polyglactin 910
Identify this instrument
Straight Kelly Hemostatic Forceps
- Transversely oriented serrations
- Serrations do not extend the entire length of the jaw (unlike with Mosquito or Crile hemostatis forceps)
- Designed for tip clamping of small to medium vessels
- Smaller than Rochester-Carmalt, bigger than Halstead-Mosquito
Identify this instrument
Periodontal Probe
- Long, thin, blunt tipped instrument
- Used to measure pocket depths around a tooth
- Establishes the state of health of the periodontium.
Identify this instrument
Lempert Rongeur
- Forceps with cupped jaws and blunted or tapered tips
- Used to remove small fragments of bone, to recontour bone, or to prepare bone for grafting
- Jaws mat be straight, curved or angled
- Lempert has finer tipped jaws and are used in more restricted areas (bulla osteotomy)
Identify this instrument.
Malleable Retractor
- Double ended blunt retractor
- Various sizes
- Can be bent at various angles
- Used for retracting viscera in abdominal and thoracic surgery
Identify this instrument
Scaler
- Removes dental deposits from above gumline
- Variety of tips and shank angles to allow access between teeth
When is caprolactone suture used?
Closure of cystotomies (non-infected bladders), subcutaneous tissues
In what application is Polyglactin 910 suture most commonly used?
Dental surgery
Identify this instrument.
Spencer Stitch Scissors
- Hooked tip used to entrap suture for cutting
- Used for post-op suture removal
- Not generally used in OR
This concentration of chlorhexidine solution is appropriate for preputial flushes and cleaning open wounds:
0.05%
Identify this instrument.
Hohmann Retractor
- Various sizes with variety of tip lengths and styles (blunt vs. sharp)
- Used to lever muscle and soft tissues away from surgical field and bone during orthopedic surgeries
Identify this instrument
Freer Periosteal Elevator
- Small periosteal elevator
- Double ended
