| GROUND POINT WIRE NEEDLE | has a point with sharp edges, but the round body of a tapered needle |
| STAINLESS STEEL MESH | a material that is rigid and hard to apply, resulting in discomfort for the patient |
| TAPERED POINT NEEDLE | has a round shaft without a cutting edge, penetrates tissue without cutting it |
| REVERSE CUTTING NEEDLE | consists of opposing cutting edges that extend to the full length of the shaft |
| LINEAR CUTTER | delivers double line of staples, the blades pass between to divide tissue |
| POLYTETRAFLUOROETHYLENE MESH | soft, flexible material, not absorbable, not used in the presence of infection |
| LIGATION CLIP | used to occlude a single small suture, such as a vessel or duct |
| CONTROL RELEASE NEEDLE | a needle that pops of the suture strand by tugging |
| LINEAR STAPLER | inserts two straight, staggered, evenly spaced, parallel rows fo staples |
| INTRALUMINAL STAPLE | fires double rows of staples with a knife located within the head used for trimming |
| SIDE CUTTING NEEDLE | used mainly for opthalmic procedures, as they dont penetrate deeper tissue |
| TROCAR POINTS | has three sharp cutting edges that end in a sharp cutting tip |
| LIGATING CUTTER | ejects two ligating clips dividing tissue between clips with single activation |
| POLYESTER FIBER MESH | least inert of synthetic meshes; should never be used in presence of infection |
| POLYGLACTIN 910 MESH | an absorbable material that provides temporary support during healing |
| CONVENTIONAL CURRING NEEDLE | consists of three cutting edges, directed along the inner curve of the needle |
| BLUNT POINTS | have round shaft that end in a blunt tip |
| CLOSED EYE NEEDLE | round or square hole, loaded by inserting suture material through the hole |
| FRENCH EYE NEEDLE | loaded by pulling the taut strand into a V-shaped area just above the eye |
| Which layer is typically not closed with suture? Does not tolerate suture material well? | MUSCLE |
| Best needle for suturing skin... | REVERSE CUTTING |
| Exposure of visera through the edges of a totally separated wound | EVISCERATION |
| Skin staples are _____ reactive to the human body, when compared to plain gut suture | LESS |
| _______ would be used to tie off deep bleeding vessels that have been occluded with a hemostat clamp | TIE-ON-A-PASS |
| A suture packet that is beige in color is | CHROMIC GUT |
| Which phase of wound healing begins within minutes of injury and is manifested by heat, redness, swelling, pain, and loss of function? | LAG |
| Abnormal attachment of two surfaces or structures that are normally separated | ADHESION |
| Pathological, surgical, or traumatic formation of an opening between two normally seprated organs or spaces | ANASTOMOSIS |
| Returned to proximity; brought together sides or edges | APPROXIMATED |
| A suture material manufactured from the submucosa of sheep intestine or serosa of beef intestine treated with chromium salts to delay the rate of absorption | CHROMIC GUT |
| Wound that persists for an extended period of time | CHRONIC WOUND |
| Scar | CICATRIX |
| A space that remains in the tissues as a result of failure of proper closure of a surgical wound | DEAD SPACE |
| Removal of devitalized tissue and contaminants | DEBRIDEMENT |
| Partial or total separtion of a layer or layers of tissue after closure of a wound | DEHISCENCE |
| Interuption of a closed wound or traumatic injury that exposes the viscera | EVISCERATION |
| Type of healing that occurs with primary union that is typical of an incision opened under ideal conditions; Healing occurs from side to side, dead space has been eliminalted and the wound edges are accurately approximated | FIRST INTENTION |
| A type of needle in which the suture must be threaded by pulling the strand into a V-shaped area jusst above the eye | FRENCH EYED NEEDLE |
| Easily torn or crumbled | FRIABLE |
| Abnormal protrusion of an organ or other body structure through an opening in a covering membrane or muscle | HERNIATION |
| Patient whose immune system has decreased due to disease, or intentionally decreased with immunosuppressive drugs for organ transplant patients to prevent organ rejection | IMMUNOSUPPRESSED PATIENT |
| The body's protective response to injury or tissue destruction | INFLAMMATION |
| Cut or tear | LACERATION |
| The placement of a suture tie around a vessel or other anatomical structure for the purpose of constriction | LIGATED |
| Suture material made of a single thread like structure | MONOFILAMENT |
| Sterile fine mesh guaze that is loosely placed in a chronic wound or one that has been left open to heal by second intention | PACKING |
| Main suture that approximates the wound edges for first intention healing to occur | PRIMARY SUTURE LINE |
| A synthetic coating used on certain types of nylon suture material to reduce the drag through tissue | PTFE (POLY-TETRA-FLUORO-ETHYLENE) |
| Healing that occurs when a wound fails to heal by primary union, or the wound is left open and allowed to heal from the inside to the outside by filling with granulation tissue | SECOND INTENTION |
| Sutures placed to support and ease the tension on the primary suture line, thus reinforcing the wound closure and obliterating any dead space | SECONDRY SUTURE LINE |
| Strand of suture material with an eyeless needle attached by the manufacturer; the needle is continuous with the suture strand | SWAGED |
| Amount of pull or tension that a suture strand will withstand before breaking; expressed in pounds | TENSILE STRENGTH |
| Healing that occurs when two granulated surfaces are approximated; also referred to as delayed primary closure | THIRD INTENTION |
| Thin strips made of silicone that can be placed around a vessel, nerve, or duct for the purposes or retracting or isolating; the loops are colored for easy identification of the retracted structures | VESSEL LOOP |
| CLASS I-CLEAN-INFECTION RATE 1-5% | Incision made under ideal surgical conditions; No break in sterile technique during procedure; Primary closure; No wound drain; No entry to aerodigestive or genitourinary tract |
| CLASS II-CLEAN CONTAMINATED-INFECTION RATE 8-11% | Primary closure; Wound drained; Minor break in sterile technique occurred; Controlled entry to aerodigestige (included billary tract) or genitourinary tract |
| CLASS III-CONTAMINATED-INFECTION RATE 15-20% | Open traumatic wound (less than 4 hours old); Major break in sterile technique occurred; Acute inflammation present; Entry to aerodigestive (includes billary tract) or genitourinary tract with spillage |
| CLASS IV-DIRTY/INFECTED-INFECTION RATE 27-40% | Open traumatic wound (more than 4 hours old); Microbial contamination prior to procedure; Perforated viscus |
| CLOSED WOUND | The skin remains intact, but underlying tissue suffer damage |
| OPEN WOUND | The integrity of the skin is destroyed |
| SIMPLE WOUND | The integrity of the skin is destroyed. There is no loss or desstruction of tissue nd there is no foreign body in the wound |
| COMPLICATED WOUND | Tissue is lost or destroyed, or a foreign body remains in the wound. |
| CLEAN WOUND | Wound edges can be approximated and secured. A clean wound is expected to hel by first intention. |
