Ejects 2 ligating clips dividing tissue dividing tissue between clips with single activation
Fires double row of staples with knife located within the head used for trimming
Soft, flexible material, not absorbable, not used in the presence of infection
Conventional Cutting Needle
Consists of three cutting edges, directed along the inner curve of the needle
Has a round shaft without a cutting edge, penetrating tissue without cutting it
Consists of opposing cutting edges that extend to the full length of the shaft
Stainless Steel Mesh
A material that is rigid and hard to apply, resulting in discomfort for the patient
Which of the following methods would be used to tie off deep bleeding vessels that have been occluded with a hemostat clamp?
A patient arrives at the emergency room with a stab wound to the left thigh that occurred 1 hour previously. What wound class does this injury belong to?
To replace the mesh covering the facial defect created by an inguinal hernia that is infected, a surgeon may use
Polypropylene (Prolene) mesh
Which phase of wound healing begins within minutes of injury and is manifested by heat, redness, swelling, pain, and loss of function?
Ligature reels are radiolucent (Black) and are not part of the count. T or F
False - they are radiopaque (White) and ARE part of the count.
Abnormal protrusion of an organ or other body structure through an opening in a covering membrane or muscle.
Primary Suture Line
Main suture that approximates the wound edges for first intention healing to occur.
Secondary Suture Line
Sutures placed to support and ease the tension on the primary suture line; reinforcing the wound closure.
Third Intention (Delayed Primary Closure)
Healing that occurs when two granulated surfaces are approximated; also referred to as delayed primary closure.
Phases of Wound Healing by First Intention (Primary Union)
Phase 1: Lag Phase or Inflammatory Response Phase
Phase 2: Proliferation Phase
Phase 3:Maturation or Differentiation Phase
Second Intention (Granulation)
Healing that occurs when a wound fails to heal by primary union or wound is left open and allowed to heal inside out.
First Intention (Primary Union)
Type of healing that occurs with primary union that is typical of an incision opened in ideal conditions. 70%-80% of original strength.
During which phase of wound healing is the strength of the wound limited to the suture holding it together?
Lag phase (inflammatory)
1st Intention, Phase 1: Lag Phase or Inflammatory Response Phase
This stage begins within minutes of injury and lasts approximately 3-5 days.
1st Intention, Phase 2: Proliferation Phase
This stage begins on approximately the third postoperative day and continues for up to 20 days. 25%-30% of its original tensile strength.
1st Intention, Phase 3: Maturation or Differentiation Phase
This stage begins on the 14th postoperative day and lasts until the wound in completely healed (up to 12 months)
Order of occurrence in which primary intention healing occurs:
Lag phase: Inflammation occurs, with heat, swelling, pain, redness, loss of function
Class I: Classification of Surgical Wound
Clean (Infection Rate 1-5%)
-Incision made under ideal surgical conditions
-No break in sterile technique during procedure
-No wound drain
-no entry to aerodigestive or genitourinary tract
Class II: Classification of Surgical Wound
Clean Contaminated (Infection Rate 8-11%)
-Minor break in sterile technique occurred
-Controlled entry to aerodigestive (includes biliary tract) or genitourinary tract
Class III: Classification of Surgical Wound
Contaminated (Infection Rate 15-20%)
-Open traumatic wound (less that 4 hours old)
-Major break in sterile technique occurred
-Acute inflammation present
-Entry to aerodigestive (includes biliary tract) or genitourinary tract with spillage
Class IV: Classification of Surgical Wound
Dirty/Infected (Infection Rate 27-40%)
-Open traumatic wound (more than 4 hours old)
-Microbial contamination prior to procedure
The integrity of the skin is destroyed. Includes 4 different types of wounds-Simple, complicate, clean, contaminated
Simple wound - form of open wound
The integrity of the skin is destroyed. There is no loss or destruction of tissue and there is no foreign body in the wound.
Complicated wound - form of open wound
Tissue is lost or destroyed, or a foreign body remains in the wound.
Clean wound - form of open wound
Wound edges can be approximated and secured. A clean wound is expected to heal by first intention.
Contaminated wound - form of open wound
Contamination occurs when a dirty object damages the integrity of the skin. A contaminated wound can become infected within a short period of time. Debridement or excision of infected and/or necrosed tissue may be necessary, followed by thorough irrigation of the wound to further clean the wound and wash out the contaminants.
