NEEDLES AND SUTURES

NEEDLES AND SUTURES

NEEDLES

Round-bodied needles

Used most often for suturing

Subcutaneous tissue

and muscle

All internal organs

Cutting

Cutting-edge needles have sharp edges commencing at the point

and prolonged along their shafts

to help them penetrate dense and tough tissues such as skin or tendon.

SUTURES

Absorbable

Catgut(plain) (98% collagen) suture for small vessals

Catgut(chromic) treated in cromic bath blood vessall ligation and internal organn

Polyglycolic acid Synthetic polymers uses similar to catgut

Nonabsorbable

Silk

Linen

Cotton

Synthetic nylon ethilon

Metal wire

NEEDLE HOLDERS

NEEDLE HOLDERS

Needle holders are modified box joint-locking forceps designed to hold curved needles.

The surgeon should thus be able to manipulate the needle with ease during suturing.

Since the function of needle holders is to grasp needles,

The instruments look like artery forceps also it has additional features, which are as follows:

· Serration at the tips to prevent slipping of needle.

· Shafts with rings for thumb and fingers.

· Locking device.

Fine needle holders are damaged by large needles,

and small needles are damaged by large needle holders.

Te varieties in use are as follows:

· Mayo needle holder

· Gillies needle holder

· Naughton-Morgan needle holder

· Kilner needle holder

· Mayo-Hegar needle holder

Micro vascular needle holder

Identification

· They have shorter blades as compared to a haemostatic forceps.

· Blades are serrated in both directions to enable a firm grip on needle.

· There is a catch for long-term holding.

· The blade can be straight or curved.

Needle holders are commonly used in surgery to hold a needle with its suture.

Where to hold the needle with a needle holder?

· Just behind its mid point, which gives maximum advantage in curving action.

CRUSHING CLAMPS

Crushing clamps

When is GI re-section required?

Re-section of bowel is required in cases of gangrene of the bowel (which may be caused by strangulation, thrombosis) or cancer.

The special instruments required are

·       Crushing clamps

·       Non-crushing clamps.

Crushing clamps

Crushing clamps are generally used with an objective to crush the muscle coat of the bowel thus obliterating the vascular supply.

These crushing clamps thus have

·       Blades that are heavy and strong

·       Blades of parker-Kerr are curved and of Lang-Stevenson are straight

·       Loops for finger

·       A catch for gradual crushing.

Identification points

·       The instrument is heavy.

·       The jaws appose closely.

·       These occlude lumen and vessels.

·       These are used on the segment that is removed from the body.

These clamps are of three types:

(a)    Payr’s smaller crushing clamp

(b)   Payr’s smaller clamps

(c)    Parker-Kerr’s crushing clamps.

Identification points

·       Payr’s gastric crushing clamps have heavy blades and handle.

·       The joints are 4 and these double the force of action of the blades.

·       The jaws have longitudinal serrations.

·       The jaws are long so as to reach from lesser to greater curvature of stomach.

GASTRIC AND INTESTINAL CLAMPS

INTESTINAL CLAMPS

These clamps are large tissue forceps with the primary function of occluding the bowel lumen

These non crushing clamps cause no permanent damage to the bowel

They when applied prevent spillage of bowel content during surgery.

They also occlude the blood vassals,and no bleeding occurs.

Manipulation of the bowel is easy and anastomosis of bowe is possible/

The varieties in use are:

Doyans

Kockers

Lane

Lane twin anastomosis clamp
