#10 Surgical Blade

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
