Needle Holder
A Dental Needle Holder, also called needle driver, is a surgical instrument, similar to a hemostat, used by doctors and surgeons to hold a suturing needle for closing wounds during suturing and surgical procedures. The parts of a simple needle holder are the jaws, the joint and the handles. Most needle holders also have a clamp mechanism that locks the needle in place, allowing the user to maneuver the needle through various tissues. To maintain a firm grip on the needle, the jaws are often textured and short compared to the shank. Needle holder are used to grasp suture needle when suturing tissues. The jaws of the needle holder undergo metal –to-metal contact causing rapid wear of the grasping surfaces. Needle holder should be tested for function regularly by placing and appropriate sized needle in jaws and nothing if needle rotation is possible (indicating that repair is necessary).
PARTS
Shaft of Body Shank
It lies between joint and finger bows
Finger Bow
It is used for holding the instruments
Catch / Ratchet
It lies between shaft and finger bow. When the catch/ratchet are pressed; the blades are kept in close position.
USES
It is used to hold the needle.
- The inner surface of tip has crisscross serration and a small groove for firm grasp of the curved needle
- Blades are having cris-cross or transverse serrations and in the center of the blade there is groove
- Smallsurgical forceps with locking handles; used to carry a suture needle
JOINT
- It is present between body and shaft
- It is having modified box joint
- The box joint is placed very close to tip to give adequate pressure because of the lever effect.
- Shaft passes in the slot of other shaft.
How to Hold the Needle Holder
- Curved needle is hold by needle holder, at the junction between anterior 2/3 and posterior 1/3 of the needle
- This gives maximum mechanical advantage of curved needle
- If needle is hold nearer to the tip, the mechanical advantage is less but the penetrating power is more
- If we hold needle to nearer to eye, chances of breakage of needle nearer to eye is more.
