VS105 Handout #3 Unit #1- SURGICAL INSTRUMENTS DESIGN AND FUNCTION Part 3 Objectives: 1. Identify the uses for hemostatic forceps 2. Classify the 8 hemostatic forceps using their unique physical characteristics and their use 3. Recognize the 4 types of tissue grasping forceps and their use 4. Identify the 3 different needle drivers used in veterinary medicine 5. Classify the 2 towel clamp variations HEMOSTATIC FORCEPS Used to clamp the ends of ______________________to stop bleeding (____________________ instruments) Vary in size, shape and the direction of the serrations on the grasping surface Available with straight or curved ends All have ______________ devices and __________________ When using hemostatic forceps, the _________________size that will accomplish the task, the better. It is important to grasp only as much tissue as necessary A) HALSTEAD MOSQUITO HEMOSTATIC FORCEPS Delicate forceps for clamping ___________ vessels. Small jaws with fine _______________________serrations that extend the entire length of the tip o allows for greater________________ B) KELLY HEMOSTATIC FORCEPS Larger than mosquito forceps – 5 inch length ________________________serrations covering only _____ of the jaws Used for medium sized vessels or small tissue masses Serrations do not go all the way down the jaw C) CRILE HEMOSTATIC FORCEPS Similar to the Kelly hemostat except that the serrations extend along the jaws the entire length About __________ D) KOCHER HEMOSTATIC FORCEPS Similar to Kelly’s – 5 ½ Inches _____________________(transverse) serrations along the entire length with 1X2 ______________on the tips to ensure a firm grip Aggressively grasps medium to heavy tissue or occludes heavy, dense vessels E) ROCHESTER PEAN HEMOSTATIC FORCEPS ___________ forceps ( usually 8 “ long) for crushing large tissue bundles and vessels Horizontal (___________________) serrations run down the whole jaw – no teeth Jaw length is quite long Clamps large vessels or large tissue/muscle masses F) ROCHESTER OSCHNER HEMOSTATIC FORCEPS Similar to Rochester Pean but with interdigital teeth on the end of the forceps Similar to Kocher but larger – about 7- 8” long G) ROCHESTER CARMALT HEMOSTATIC FORCEPS Same _________ size as the Rochester Pean- 8” long and 3 ½“ jaws Serrations are ____________________________ along the length of the jaws – crush less than transverse Transverse serrations cross hatch (cross serrated) the ______ to help prevent slippage Clamp large vessels or large tissue masses H) FERGUSON –ANGIOTRIBE FORCEPS Not technically a true “hemostat” Very strong forceps that is very ___________________ Used to _____________ tough tissue bundles – that will not have to be viable in the body o Uterine “stump” in a spay surgery Distinct tongue and groove pattern TISSUE GRASPING FORCEPS Used for grasping portions of tissue Maintains the hold with the use of the ratchet device on the handle Designed for __________________ tissue trauma A) ALLIS TISSUE FORCEPS Stabilize tissue Have opposing edges with _________________ Grasps tissue in a fairly traumatic way Should not be used on intestines – may damage Usually used for grasping tough tissue or tissue being removed from the animal B) BABCOCK INTESTINAL FORCEPS Used for holding intestine and muscle groups Two opposing loops like __________ Handle delicate tissue without trauma C) DOYEN INTESTINAL FORCEPS Straight or curved Have oblique or longitudinal serrations Used for loops of __________________ or holding off the intestine to prevent spillage during surgery Jaws don’t completely close so minimal trauma to tissue D) FORESTER SPONGE FORCEPS Straight or curved Mainly used to hold ____________________________ Used for prepping surgery, or during surgery to swab blood NEEDLE HOLDERS/DRIVERS These are forceps specifically designed for holding curved suture _______________ during surgery when suturing or tying knots The only instrument designed specifically to hold metal May have suture cutting ________________ incorporated into the jaws Cross hatch serrations on the tip help prevent needle slippage A. Olsen-Hager Needle Holder/Driver Needle holder and ___________________ combined Advantage – don’t need extra instrument (______________) to cut suture Disadvantage – accidentally cutting suture material B. Mayo-Hegar Needle Holder/Driver _____________________________only – no scissor Usually has a groove in the tip to allow for better needle gripping with small serrations on the tip C. Mathieu Needle Holder/Driver Needle holder only Good for ____________________people – can be used with either hand Have a ratchet in the handle that releases when additional pressure is applied to the spring handles TOWEL CLAMPS Used for attaching ____________ and drapes to each other and to the patient They have a pointed end which is intended to pierce the patients_________ A) BACKHAUS TOWEL CLAMPS Most common type Variety of sizes _________________ _______________________________and rounded jaws allow for firm attachment B) ROEDER TOWEL CLAMPS Two ______________ on the jaws prevent deep tissue penetration and the towel from slipping
