Sharp/Blunt Suture Scissors
- Longitudinal serrations along jaws with crosshatching tips
- Least traumatic hemostatic forceps
- Provide secure grasp of tissue with minimal risk of cutting or tissue slippage
- Mainly clamp vascular pedicles but also vessels, large tissues, and stumps
Rochester-Carmalt Hemostatic Forceps
interdigitating short teeth are slightly traumatic and used to grasp tissue like skin, fascia, and intestine
Allis Tissue forceps
broad, flared ends with smooth tips used for delicate tissue like intestine and bladder
Babcock tissue forceps
to temporarily occlude lumen of bowel. Are non-crushing intestinal occluding and have longitudinal serrations
Doyen tissue forceps
for surgical and wound suction ABDOMEN. It is used to clean debris and liquids from the surgical site. It has multiple holes in the end and is designed to avoid clogging on fat particles.
Poole suction tip
offers ultra-precise suctioning of secretions during surgery-ORTHODPEDICS
Frazier suction tip
the most common suction instrument in the world
for use in BLADDER Sx.
It has a large opening surrounded by a bulbous head, designed to allow effective suction without damaging surrounding tissue. It is used to suction oral secretions in order to prevent aspiration, as well as other bodily fluids
Yankauer suction tip
used for lifting bone or removing periosteum—to remove periosteum and other soft tissues from the surface of bones. They are designed with a blade-like structure at the end of a stout handle. The blade may have sharp or blunt edges and come in various sizes
Periosteal elevator
used for debriding cartilage or bone defects—to scrape the surface of relatively dense tissue to remove loose or degenerate tissue (bone marrow, necrotic bone, cartilage flaps, abscess material). It has a small cup-like structure at the end of a handle. The cup has a very sharp cutting edge and comes in various sizes
Bone curette
used with a mallet to cut through bone—to cut or shape bone and cartilage, it is tapered on both sides to form the cutting edge and is used with a steel or plastic mallet
Osteotome
needed for hand driving pins through bone–the
chuck is the end piece that connects to a handle and is used to place pins in broken bones, the key is used to tighten and untighten the chuck’s hold on the orthopedic pin
Jacob’s chuck and key
used to crush or bite bone when debriding or removing bone—to cut and remove pieces of bones. These instruments come in various types and sizes
Rongeur
larger than Senn with broad, blunt edges on each end for retraction of large amounts of tissue (hand held, used to retract shallow incisions: skin, fat, muscle; used in all surgery types)
Army-Navy Retractor
small, double ended retractors with three small fingerlike projections on one end and a flat, curved blade on the other (hand held—double ended retractor one side is “L” shaped and the other side has 3 bent prongs to use in all surgery types)
Senn retractor
spatula shaped ends,
retract soft tissue away and expose the bony segments
Hohmann retractor
can be bent by the surgeon to conform to the structure
or area of the body being retracted (hand held, metal retractors that can be molded to different shapes to assist in tissue retraction such as abdominal organs, muscle, skin, etc)
Ribbon (malleable) retractor
self-retaining retractors maintain tension on tissue and are held open with a box-lock or another device
Gelpi retractor
self-retaining retractors maintain tension on tissue and are held open with a box-lock or another device (a set screw)-used to retract the abdominal wall
Balfour retractor
self-retaining retractors maintain tension on tissue and are held open with a box-lock or another device—many comb like extensions on ends (self-retaining, used in all types of surgery, best for retraction of shallow incisions. Tips have 3-4 pronged ends)
Weitlander retractor
self-retaining retractors maintain tension on tissue and are held open with a box-lock or another device (a set screw)-used during thoracotamies (self-retaining-used in thoracic surgery to retract ribs to increase space between ribs)
Finochietto retractor
