This document discusses surgical instruments and aseptic technique. It covers commonly used surgical instruments like scalpels, scissors, needle holders, forceps and their components and materials. It also discusses techniques like electrosurgery, monopolar vs bipolar electrosurgery and lasers. Further, it outlines the role of technicians during surgery to maintain asepsis and assist the surgeon. The objectives covered include naming instruments, describing cleaning and sterilization methods, and outlining preparation requirements for patients and surgical teams.

Prevention of Accidents in An Operation Theatre-NURSINGMariaKuriakose5
This is a PowerPoint made to explain various hazards in an operation theater and with its preventive measures.This will hepl the nursing students to go through the important points rather than going into deep studies.
Planning & day today management of OT services is very complex and needs to be understood by all Hospital administrators for successfully running a hospital.

routinely included in general and emergency
surgical packs for small and large animals
• Describe procedures for cleaning, packing,
and sterilizing instruments
• Differentiate between sterilization and
disinfection
4. 4

methods of sterilization and methods of
quality control of sterilization methods
• State safe storage times for sterile packs
• List and describe common antiseptic and
disinfectant agents
5. 5
Learning Objectives

patients, including skin preparation, patient
positioning, and draping
• Describe preparation requirements for the
surgical team and explain the procedures that
may be used for hand scrubbing before
surgery
• Describe the procedure for donning surgical
attire
• Describe procedures for opening sterile items
6. 6
Technician’s Role During Surgery
• Maintain aseptic technique
• Assist in surgery
– Immobilization of body part
– Tissue retraction
– Hemostasis control
• Anticipate instruments needed
7. 7
General Surgery Instruments
• Thousands of different instruments
– Increase efficiency
– Ease performance
• Specific purpose for each instrument
8. • The most commonly used materail is stainless
steel, which is an alloy of iron, chromium, silicon,
manganese, nickel, molybdenum, sulfur,
phosphorus, and titanium. There are 2 basic
compound types:
• Martensitic- high carbon and low chromium
content, rendering it very strong, highly magnetic,
and susceptible to corrosion. i.e. thumb forceps,
hemostats, retractors,etc.
• Austenitic- stainless steel is compounded mainly
of chromium and nickel. Superior in that is has
high tensile strength and is very resistant to
corrosion i.e. implants, pans, bowls, handles, and
trays
Discuss role of technician in surgery assistance—hold a body part, hold an instrument, hold off a bleeding tissue, etc.
Figure shows scalpel handles and attachable surgical blades.
Bard-Parker No. 3 handle uses blades 10, 11, 12, and 15.
No. 3 handle and No. 10 blade are commonly used in small animal surgery.
Bard-Parker No. 4 handle uses blades 20-22.
No. 4 handle and No. 20 blade are commonly used in large animal surgery.
CO2 and the ND:YAG are the lasers most common to veterinary medicine.
Advantages: hemostasis, less postoperative swelling and pain
Disadvantages: delayed wound healing, safety issues
In monopolar electrosurgery, current passes from handpiece through patient, to a metal plate that is placed under the patient.
Figure on left shows monopolar electrosurgery handpiece; if handpiece has cutting-coagulation button, foot switch is not needed.
Surgeon passes end of cord to nonsterile assistant who plugs it into electrosurgical unit.
Figure on right shows ground plate on surgery table with gel to improve skin contact when animal lies on it.
In bipolar electrosurgery, current passes between two tips on the handpiece that grasp the tissue; no ground plate is needed.
Figure shows bipolar handpiece, which is sterilized for use.
Nonsterile foot switch is needed for activation.
Scissors are specifically designed for many purposes, including tissue dissection and cutting suture or bandage materials.
(left to right) Sharp-sharp operating scissors, Mayo dissecting scissors, and Metzenbaum dissecting scissors
(at right, from top to bottom) Lister bandage scissors, wire-suture-cutting scissors, and Littauer suture removal scissors
Operating scissors: straight vs. curved; blunt-blunt, blunt-sharp, or sharp-sharp
Mayo-dissecting scissors cut tough tissue.
Metzenbaum dissecting scissors for soft tissue dissection.
Lister bandage scissors cut bandages without cutting skin.
Designed for holding curved suture needles during suturing and for performing instrument suture ties.
Mayo-Hegar needle holder on the left
On the right, Olsen-Hegar needle holder has built-in suture scissors, which negates the need for an assistant to cut suture.
Thumb forceps hold tissue while dissecting or suturing.
(left to right) Brown-Adson thumb forceps, Adson thumb forceps, rat-tooth thumb forceps, DeBakey vascular thumb forceps, Russian thumb forceps, dressing thumb forceps
(left to right) Brown-Adson thumb forceps, Adson thumb forceps, rat-tooth thumb forceps
Brown-Adson used during suturing and wound closure.
Rat-tooth used on skin or fascia.

DeBakey used for vascular surgery.
Russian used for needle handling.
Dressing forceps have no teeth; used for applying and removing dressings.
Tissue forceps clamp and hold tissue with self-locking mechanism.
(left to right) Allis tissue forceps, Babcock tissue forceps, Doyen intestinal tissue forceps, Backhaus towel clamps (two sizes)
Doyen intestinal tissue forceps (third from left) is used to occlude and hold intestines.
Backhaus towel clamps (on far right) hold drapes and towels to the patient.
Roederer towel clamp (not pictured) has a metal ball attached to the jaws that prevents deep tissue penetration and prevents the towel from slipping toward the box lock of the forceps.
(left to right) Allis tissue forceps and Babcock tissue forceps
Allis forceps grasp and crush tissue.
Babcock forceps grasp, but do not crush.
These are tissue forceps that crush blood vessels to stop bleeding.
(left to right) Halsted mosquito hemostatic forceps, Kelly forceps, Crile forceps
Halsted forceps are used on small vessels.
Kelly and Crile forceps are used on larger vessels.
(left to right) Kelly and Crile forceps
Curved jaws of Kelly forceps is only half-grooved.
Crile forceps has straight jaws.
(left to right) Rochester-Carmalt forceps, Rochester-Pean forceps, Rochester-Ochsner forceps
Rochester-Carmalt forceps are large crushing forceps, commonly used in spaying.
Rochester-Pean forceps are used on large vessels and tissue bundles.
Rochester-Ochsner forceps are used most often in large animal surgery.
(left to right) Rochester-Carmalt forceps, Rochester-Pean forceps, Rochester-Ochsner forceps
Rochester-Carmalt forceps (on left) have longitudinal grooves and cross-grooves at the tip to provide more traction.
Rochester-Ochsner forceps (on right) have interdigitating teeth at the tips that aid in grasping the tissue.
