INSTRUMENTS

Classification by size and shape and size of tips

Hemostatic forceps and hemostats may be curved or straight.

CLAMPING AND OCCLUDIN G

INSTRUMENTS

Comparison of Kelly and Mosquito tips

• Both are transversely serrated. • Mosquito hemostats (A) are more

delicate than Kelly hemostatic forceps (B).

Mosquito hemostats (A) have a smaller, finer tip.

GRASPING AND HOLDING

INSTRUMENTS

Grasping and holding instruments are used to hold tissue, drapes or sponges

GRASPING AND HOLDING

INSTRUMENTS

Allis: An Intestinal Tissue Forceps

• Interdigitating short teeth to grasp and hold bowel or tissue.

• Slightly traumatic, use to hold intestine, fascia and skin.

GRASPING AND HOLDING

INSTRUMENTS

Babcock: An Intestinal Tissue Forceps

A Babcock is used to grasp delicate tissue (intestine, fallopian tube, ovary). Available in short and long sizes.

• More delicate that Allis, less directly traumatic.

• Broad, flared ends with smooth tips.

• Used to atraumatically hold viscera (bowel and bladder).

GRASPING AND HOLDING

INSTRUMENTS

Sponge Forceps (Ovum Forceps, Pick up Forceps

• Sponge forceps can be straight or curved.• Sponge forceps can have smooth or serrated jaws.• Used to atraumatically hold viscera (bowel and bladder).

Sponge Forceps holding a 4 X 4.

Sponge Forceps

Used to hold gauze squares or sponge to “mop up” the surgical site

Jaws are serrated

GRASPING AND HOLDING

INSTRUMENTS

A Kocher is used to grasp heavy tissue. May also be used as a clamp. The jaws may be straight or curved. Other names: Ochsner.

GRASPING AND HOLDING

INSTRUMENTS

• Locking forceps with curved, pointed tips.• Towel clamps secure drapes to a patient's

skin. They may also be used to hold tissue.

Towel Clamps or Towel Clips

large & small towel clips

Towel Clamp

Adds weight to drapes and towels to ensure they stay in place

Allow exposure of the operative site

GRASPING AND HOLDING

INSTRUMENTS

THYROID TENACULUM

GRASPING AND HOLDING

INSTRUMENTS

HEMORRHOIDAL / LUNG CLAMP

GRASPING AND HOLDING

INSTRUMENTS

Forceps: consist of two tines held together at one end with a spring device that holds the tines open. Forceps can be either Tissue or Thumb forceps.

Plain Thumb Forceps

Used to hold tissue in place when applying sutures Used to gently move tissues out of the way during

exploratory surgery

Used to insert packing into or remove objects from deep cavities

GRASPING AND HOLDING

INSTRUMENTS

Tissue Forceps

• Interdigitating teeth hold tissue without slipping.

• Used to hold skin/dense tissue.

Adson Forceps

Adson Forceps are either smooth: used to grasp delicate tissue; or with teeth: used to grasp the skin.Other names: Dura forceps.

1x2 Toothed Tissue Forceps

Used for grasping and holding tissue, muscle or skin surrounding a wound

Single toothed on one side; fits between two teeth on the other side

Available as 1x2 or 2x3 or 3x4

GRASPING AND HOLDING

INSTRUMENTS

Needle Holders

Needle holders are used to holdneedles when suturing.

They may also be placed in the sewingcategory.

short, medium & long(top to bottom)

• Good quality is ensured with tungsten carbide inserts at the tip of the needle holder.

• Heavy, with mildly tapered jaws.• No cutting blades.

Mayo-Hegar Needle Holder

Needle Holder

Used to hold and pass a suturing needle through tissue

Has groove to hold needle within jaws

GRASPING AND HOLDING

INSTRUMENTS

Needle holder with suture.

RETRACTING AND EXPOSING

INSTRUMENTS

Retracting and exposing instruments are used to hold back or retract organs or tissue to gain exposure to the operative site.

They are either "self-retaining" (stay openon their own) or "manual" (held by

hand). When identifying retractors, look at the

blade, not the handle.

Zenn Retractors

• Blades at each end. • Blades can be blunt (delicate) or

sharp (more traumatic, used for fascia).

Skin/Hook Retractors

An Army-Navy retractor (manual) is used to retract shallow or superficial incisions.Other names: USA, US Army.

A Richardson retractor (manual) is used to retract deep abdominal or chest incisions.

Deaver retractor (manual) is used to retract deep abdominal or chest incisions. Available in various widths.

A malleable or ribbon retractor (manual) is used to retract deep wounds. May be bent to various shapes.

Weitlaner• Ends can be blunt or sharp.• Has rake tips.• Ratchet to hold tissue apart.

Weitlaner Retractor

MASTOID/SCALP RETRACTORS

A Balfour with bladder blade (self-retaining) is used to retract wound edges during deep abdominal procedures.

Finochieto Rib Spreader

Nasal Speculum

Used to spread nostrils during examination

Vaginal Speculum

Used during gynecological exam or procedure

Dilates the opening of the vaginal cavity, allowing for inspection of the vagina and cervix

Facilitates access for observation and treatment

Anoscope with Obturator

Used to visualize the rectum and lumen of the sigmoid colon

Used to examine anal canal and distal aspect of the rectum

Consists of a stylus or removable plug (Obturator) used during the insertion of many tubular instruments (Anoscope).

Groove Director

Probe

Intestinal Stapler

Principles of instruments handling Safety (patient and staff)

Economy of movements

Relaxed handling.

Avoidance of awkward movements.

Scalpels

The scalpel is held with thumb, middle and ring finger while the index finger is placed on the upper edge to help guide the scalpel.Long gentle cutting strokes are less traumatic to tissue than short chopping motions.

The scalpel should never be used in a "stabbing" motion.

This is the wrong way to hold the scissors. The ring finger should be inserted into the ring.

This is also the wrong way to hold the scissors. The tips of the scissors should be pointing upwards.

Scissors and Hemostats

•The thumb and ring finger are inserted into the rings of the scissors while the index and middle finger are used to guide the instrument.

•The instrument should remain at the tips of the fingers for maximum control.

Thumb and tissue Forceps

Thumb forceps are held like a pencil.

Thumb Forceps are not called 'tweezers'.

Thumb Forceps are not held like a knife.
