  • GraspingRetraction – Sharp – Traumatic – Trocar –
  • Sharps and related items should be counted four times: prior to the start of the procedure; before closure of a cavity within a cavity; before wound closure begins; and at skin closure or the end of the procedure.
  • Bone Curettes -

  • Principle : COUNTER TRACTIONScalpel , 2 sponges in the incision, LAP Sponge, RAYTECS(4x4) SpongeMosquito Clamp, to Assistant or Kelly Clamp to clamp blood vessels during bleedingPEAN ( hemostat ) beyond 7 inches of HemostatsTying or cautery to promote hemostasisPoole – irrigationYankeur – Most commonly used , for bleedingFrazier – neuro, EENT
  • Adson - Fine

  • A needle holder should not be placed on a magnetic pad, because it may become magnetized.Tungsten Carbide jaws – eliminate the twisting and turning of the needleCrosshatching – provides a smoother surface and prevents damage to the needleSmooth jaws – used with small needles such as those used for plastic surgery
  • Internal anastomosis staplers – to connect hollow organ segments to fashion a larger pouch or reservoir
  • Frazier tip =
  • The heat generated by powered instruments can damage bone cells.Air powered – causes minimal heating of bone because they operate at a faster and higher speed, med-grade air / pure (99.97%) dry nitrogen is either piped into the OR or supplied from cylinder tankOperating Pressure has a range of 70 to 160psiDON’T USE EXCESSIVE PRESSUREElectrically powered – Explosion proof
  • Instruments are maintained and sterilized prior to use.Surgical instruments must be kept clean during a procedure. This is accomplished by carefully wiping them with a moist sponge and rinsing them frequently in sterile water. Periodic cleaning during the procedure prevents blood and other tissues from hardening and becoming trapped on the surface of an instrument.

  • Surgical Instrumentation
  • IMPORTANT TERMS• Atraumatic • without trauma• Traumatic • Causing Injury by penetration or crushing• Dilation • Enlarging an opening in a progressive manner• Dissection • Process of separating tissues through anatomic planes by using sharp or blunt instrumentation
  • IMPORTANT TERMS• Grasping • Holding in a traumatic or atraumatic manner• Retraction • stabilizing a tissue layer in a safe position for exposure of a part• Sharp • Instrument with a cutting edge or pointed tip(s) that is used to cut or dissect tissue
  • IMPORTANT TERMS• Trocar • A device used for penetration of tissue layers. It is commonly used for percutaneous endoscopy. It is used as a temporary pathway for gases, other instrumentation, or the removal of an organ or substance.

  • Handling INSTRUMENTS during SURGERY• Instruments are maintained and sterilized prior to use.• Surgical instruments must be kept clean during a procedure. This is accomplished by carefully wiping them with a moist sponge and rinsing them frequently in sterile water. Periodic cleaning during the procedure prevents blood and other tissues from hardening and becoming trapped on the surface of an instrument.
  • ELECTROSURGERY•INITIAL Incision is madeby a SCALPEL•Doubling the currentincreases the heatproduced fourfold•ARGON Enhanced ESUTip is held at 60 degreeangle, causing LESSTissue Damage•BUZZING – the processof coagulating theVESSELS•BUZZ should not exceedmore than 3 SECONDS
  • Electrosurgery precautions• ESU should not BE USED in the mouth, trachea, around the HEAD, or in the pleural cavity• ECG electrodes should be placed as far as possible, BURNS can occur• Rings and jewelry should be removed• DON’T USE Flammable agents• DO not immerse an active electrode in liquid• DRY Sponges can IGNITE• Investigate a repeated request for more current
  • LASER SURGERY• Light amplification by stimulated emission of radiation (LASER)• Types of LASERS = ARGON, CARBON DIOXIDE, HOLMIUM, KRYPTON, NEODYMIUM, PHOSPHATE, RUBY/XENON
  • PATIENT SAFETY in LASERS Eyes and Eyelids  Anesthetic Agents should be adequately should be protected (aluminum NONCombustible foil, moist pads)  Flexible metallic or Antiseptics must be insulated silicone NONFlammable endotracheal tubes Rectum should be  Wear high filtration packed with a MASKS for CO2 laser MOISTENED sponge ablation such as to prevent escape of condylomata (Venereal METHANE gas warts)
  • Advantages of LASERS Precise CONTROL =  Minimal TRAUMA to ACCURATE incision tissues Access to HARD to  DRY, Bloodless REACH areas SURGICAL Field (endoscopes,  Minimal THERMAL rhodium reflector effect mirrors)  Reduced RISK for Unobstructed view of INFECTION the surgical site  Prompt Healing  Reduced OPERATING Time
