Flashcards in 4: needles, suture patterns, and knots Deck (29):
1

Needle chord length

Length of straight line from tip of needle to suture attachment

2

1/4 circle needle use

ophthalmic procedures

3

straight needle use

superficial with surgeon's fingers

4

3/8 and 1/2 use

abdominal closure

5

Blunt needle use

friable tissue

6

Taper point use

delicate tissues (GI, fat, urinary bladder, muscle) small hole

7

Taper cut use

less chance for inadvertent tissue damage

8

Reverse cutting needle

most common

9

Side cutting use

ocular surgery

10

diamond point use

plastic surgery

11

Swaged needles

seamless single use

12

Eyed suture needles

large suture in orthopedic surgery increased tissue drag can become dull

13

How to handle your needle

never touch the tip pull it perpendicularly and in a linear fashion

14

appositional needle inserted on one side, go to other side and out. knot tied quick and easy takes longer and uses a lot of material

Simple interrupted pattern

15

everting used in areas of tension local ischemia of skin may result needle goes in on far side of incision, exit on near side, back in on same side and then back across the incison

horizontal mattress

16

appositional

used in areas of tension

less eversion and ischemia than horizontal matteress

 

cruciate

17

everting

stronger than horizontal mattress

time consuming

vertical mattress

18

Inverting

far near, far near

significant inversion

close hollow vicera

Lembert

19

appositional

minimize mucosal eversion

GI surgery

enhance healing

 

Gambee

20

apposisitonal

air and fluid tight

don't use where tightening may result in purse string effect

simple continuous

21

appositional

greater stablility than simple continuous

quick to place but uses a lot of suture

difficult to remove

ford interlocking

22

lots of inverting

 

continuous lembert

23

inverting

close hollow viscus

water tight

only picture i can find has the names on them 

 

cushing and connell

24

appositional

used when you dont want to remove sutures from a patient (fractious)

intradermal

25

how many throws in a typical surgical knot

4

26

how many throws when ending a continuous patter

6-7

27

formation of two opposing simple knots

even tension must be applied parallel to plane of knot

square knot

28

greater security than square knot

significatnly bulkier

 

surgeons knot
