SN1:Suture Material & Needles Part II

This non absorbable synthetic fiber coated with a plastic like material should not be used below the skin level because it can predispose a patient to a fistula and infx. The outer sheath of suture can often break allowing underlying fibers to have bacterial migration.

3 examples of polmerized caprolactum: SBV

This non absorbable suture is stainless steel and is available in monofilament and multifilament and does not support bacterial growth.

Means to go around

#O means

Eyed needles are frequently used and are reusable with various types of suture material its counterpart however will not unthread itself, has less bulk, and comes with suture material already attached. What is this called?

These are faster and easier to use then hand suturing and are named by an abbreviation of their designed function, a number may be used after the name to indicate the length of the row.

This stapler places four rows of staples and cuts between the middle two rows.

Unlike a surgical skin stapler that places only a single row of staples this stapler is used in lung resection and places double or triple rows of staples.

Used for blood vessel ligation this stapler places two staples on a vessel and cuts inbetween them.

A straight needle driven through by hand and one that resembles a regular sewing needle is called:

Special needle with the eye in the point that requires a special braided tubular suture. The only purpose is to retain a prolapsed vagina in large animals.

A double curve design needle that goes thru skin w/o having to pivot wrist and is used exclusively for large animal

Round all the to thetip with gradual taper. Used for soft tissue, internal tissue, and SQ. This type of needle is atruamatic to tissue because it pushes apart instead of cutting.

Produces a "cut out" effect and should not be used when an air tight or water tight suture line is required. Has a triangular shaped point used for skin and tougher tissue.

Has less of a cut out effect and doesn't bend or break as easily as regular cutting needle which is why they are most preferred by surgeons.

Suture pattern that directly oppose eachother

Suture patttern designed to withstand added tension

Suture pattern that turns the tissue outward and away from the patient and towards the surgeon

Suture pattern that turns the tissue towards the patient or toward the lumen of a hollow tissue organ.

Suture pattern mainly used in large animal and is similar to simple continuous but provides greater security if broken.

Is commonly used to suture skin of cattle following a rumenotomy

Used for inversion of visceral stumps or securing of "ostomy" tubes. The stump is held inverted as suture is tightened.

Used for manipulation or retraction of tissue. Usually 2 or more placed.

Suture material is passed through the stump to be ligated, tied around half of the stump then around the entire stump. Example: used to suture the uterine stump

This is a classical suture pattern for closing gut. The needle and suture penetrate serosa and muscularis but not mucosa. This pattern can be continuous or interrupted.

6-O to 10-O are mainly used for delicate surgeries like:
