2. SCIENTIFIC CRITERIA FOR THE SELECTION OF SUTURE MATERIALS AND NEEDLES
Suture material is used to keep wound together during healing process and to provide necessary support.
Surgery technique, blood circulation, mechanical stress, suture material, stretching technique, infection and systemic effects are the main factors in the healing process.
Main factors to be considered in the selection of suture material are type and strength of the tissue to be stitched, healing duration of tissue, characteristics of suture material and interaction between tissue and suture.

3. As a result of a clinical study conducted with 19 hospital and 699 surgeons in USA, it’s determined that suture preference is made according to subjective criteria and habits rather than scientific criteria.
At the conclusion section of the study, importance of the suture preference based on scientific criteria is emphasized.
This criteria can be listed as ; Tensile strength,
Ease of passage through tissue,
Knot security,
Drag of tissue by suture,
Short and long term reactions of tissue,
Handling properties,
Ease of use of use of suture,
Packing property ensuring suture getting out of package with minimum memory.

10. TYPES OF NEEDLE BASED ON THE FIELD OF SURGERY
ROUND NEEDLE
Sharp end of the needle is round.
Needle body is in the form of oval or rectangular.
Usage areas: Gastrointestinal system, urogenital system, biliary system, periton, fascia, dura, nerve, muscle, myocardium, subcutaneous fat.
CUTTING NEEDLE
It has three cutting edges which one of them is on the concave edge.

11. TYPES OF NEEDLE BASED ON THE FIELD OF SURGERY
REVERSE CUTTING NEEDLE
It’s triangular such that has a third cutting edge in the convex curvature.
This configuration provides stronger structure to needle.
Usage areas: skin, fascia, ligament, tendon, nasal cavity, pharynx, oral cavity.
TAPER CUT
Combination of round and reverse cutting needles.
Three cutting edges start from the 0.8 mm behind the round point.
Usage areas: Calcified tissues, bronchia, trachea, nasal and oral cavity, fascia, periosteum, perichondrium, uterus, ovary, tendon, ligament.

12. TYPES OF NEEDLE BASED ON THE FIELD OF SURGERY
BLUNT NEEDLE
Used for parenchymatic tissues.
Round body, blunt point.
Usage areas: fascia, paranchymatic tissue, intestine, kidney, liver, spleen, cervix tying.
SPATULA
Needle has straight body and lateral cutting edges.
They are needles that have cutting ends only on two edges. Edges are in the form of trapezoid, narrow side looks to convex and large side looks to concave side. Generally used in ophthalmic surgery and microsurgery.

13. FORMS OF NEEDLE BASED ON THE FIELD OF SURGERY
1/4: Ophthalmic and microsurgery.

14. FORMS OF NEEDLE BASED ON THE FIELD OF SURGERY
3/8: Generally used in all tissues. Skin stitches, eye, fascia, nerve, vessels, dura, gastrointestinal system, periosteum, muscle, myocardium, genitourinary system, tendon and pleura stitches.

15. FORMS OF NEEDLE BASED ON THE FIELD OF SURGERY
1/2: Generally used in all tissues. Eye, muscle, biliary system, gastrointestinal system, genitourinary system, respiratory system, skin, mouth and nasal cavity, pharynx and periton stitches.

16. FORMS OF NEEDLE BASED ON THE FIELD OF SURGERY
Straight: General use. Skin stitches, gastrointestinal system, oral and nasal cavity, pharynx and tendon stitches.

17. FORMS OF NEEDLE BASED ON THE FIELD OF SURGERY
