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

TISSUE FORCEPS

These forceps are designed to grasp tissues without crushing,they allow ease of manipulating the
tissue.
They look like haemostats except that the blades only approximate at the tips.
The tips are in the form of small teeth to reduce damage and provide good grip.
The blades above the tips, are have space for tissue gripped.
They also have rings and locks on the shafts

IDENTIFICATION
Tissue forceps look like hemostats but the blades mmet only at the tips.
There is space for tissue above the tips
There are no serrations on the blades.
There is a lock for long term holding of tissue.

The varieties are:
Allis
Lane
Babcock
Littlewood
Stile
Duval
DeBakey

ARTERY FORCEPS

HAEMOSTATIC FORCEPS

The function of haemostatic or artery forceps is to stop or prevent bleeding.
They look very much like scissors and incorporate a rachet lock on springy steel handles and crushing jaws instead of cutting blades.

Identification points

• The tips have serrations with or without teeth to provide a firm grip.
• There is also a locking device; this allows the vessels is held others can be dealt with.
• The handles have rings to accommodate the fingers.
• The tissue is grasped between the jaw tips.

ARTERY FORCEPS

Artery forceps are primarily for holding open ends of bleeding blood vessels.
The varieties are as follows:
• Spencer – Well’s artery forceps.
• Crile artery forceps
• Dunhill artery forceps
• Rochester – Ochsner artery forceps
• Kocher artery forceps

TREPHINES AND DISSECTING FORCEPS

TREPHINES
Trephines are used to create openings into the cranium for access to the structures within.

The burr holes can be used for obtaining biopsy material or for draining a collection of blood or pus.
Burr holes can also be enlarged or intervening bone removed to provide greater access to the brain.
Trephines in use are as follows:
· Rowbotham
· Buchanan
· Hudson spherical burr
· Hudson brace


DISSECTING FORCEPS

Dissecting forceps are also called thumb forceps because. These are used to grasp tissues to facilitate dissection or suturing and are of two types–toothed and non–toothed.
Dissecting forceps have two shafts and no joint. The tip is serrated and may have teeth. They provide a firm grip on tissues but the firmness depends on how much pressure put on the shafts. There is no locking catch on the shafts. Dissecting forceps could be plain or toothed. Plain forceps (no teeth) cause no damage to tissue, whereas toothed forceps give a firm grip. The varieties are as follows:
· Canadian
· Mitchell’s(toothed and non-toothed)
· Lane’s
· Adson’s

SHARP INSTUMENTS 10

Potts, DeBakey and microvascular scissors are used in vascular surgery.

Guy plaster scissors are used to cut plaster of Paris at the time of removal of the plaster or to loosen a tight plaster.

What are the special-function scissors?
Special-function scissors are scissors that have special functions such as stitch cutting and bandage cutting. These are shown in given fig.

· Stitch cutting
· Bandage cutting.

Sterilization of scissors
Boiling makes the edges blunt, thus scissors require autoclaving but, over the time, the scissors need replacement. Tungsten carbide scissors last longer.
They have gold-coloured finger loops.

Oschsner Gall Bladder Trocar
Trocars and cannulae are instruments used to drain fulid from a cavity or a sac.

Uses
Ochsner’s gall bladder trocar is used for entering a distended gall bladder so as to drain its contents.
