Use of Medical Instrument

    Neurosurgical Instruments
  1. 1. Surgical Instrumentation
  2. 2. 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
  3. 3. 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

  38. 38. HANDLING INSTRUMENTS•Standardized BASIC sets•Scrub Person counts ALLinstruments, sharp andsponges with theCIRCULATOR•Handle LooseInstruments SEPARATELY•Sort by CLASSIFICATION•PROTECT Sharps
  39. 39. Handling INSTRUMENTS during SURGERY • FREE-HAND TECHNIQUE• Know the NAME and USE• Handle INDIVIDUALLY • Watch the sterile field for LOOSE instruments• Use for the INTENDED purpose • With a MOIST, SPONGE wipe• Use of HAND SIGNALS blood and organic debris from instruments using a• Short INSTRUMENTS = Superficial DEMINERALIZED STERILE, Work DISTILLED H20• LONG Instruments = DEEP• PASS instruments DECISIVELY and FIRMLY
  40. 40. 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.
  41. 41. 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
  42. 42. 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
  43. 43. LASER SURGERY• Light amplification by stimulated emission of radiation (LASER)• Types of LASERS = ARGON, CARBON DIOXIDE, HOLMIUM, KRYPTON, NEODYMIUM, PHOSPHATE, RUBY/XENON
  44. 44. 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)
  45. 45. 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
