2
Objectives Identify components of an operative microscope
Identify microsurgical instruments and instrument design features Describe microsurgical techniques Discuss the care of the microscope Discuss the surgical consideration of the handling of the microscope
3
Advantages of Microsurgery
Restoration of wholeness of the body Advantages of Microsurgery
4
Microscope Components
Optical lens system/lighting Mounting system Electrical system Accessory items/attachments
5
Optical Lens System Has 4 main components…. Objective Lens Ocular Lens
Light Source Focusing
6
Lighting System Coaxial Most commonly used
Transferred through a fiber optic cable Paraxial One or more light tubes Tungsten or halogen bulbs Must focus light on the field
7
Mounting System Wall mount (on a bracket) Floor mount
Track mount (ceiling mount)
8
Accessories Assistant’s binoculars Microscope drape
Camera/video adapter Laser micro-adapter Remote foot control Sliding stool/chair
9
Microscope Care Tighten all joint knobs before moving
Keep body of scope close to mounting post while moving Install attachments over a bed or stretcher Keep covered with plastic to avoid damage during storage Cover foot pedal with plastic to avoid contact with blood or fluids Clean lenses with a soft, lint free cloth or paper designed for lens care
10
Additional Light Sources
Fiber-optic headlight is used when the surgeon requires a highly intense light in a small area (ex. ear, nose or deep cavity) Magnifying loupes are worn much the same as eye glasses to increase the area in size.
11
Microsurgical Technique
Dissection and repair of fine structures through better visualization Adaptation of surgical procedures from visual orientation to hands on orientation Less surgical trauma to tissue
12
Instrument Design Shape and tips
Shorter/some angled for better visualization Handles Designed to conform to hand movements Material and surface Very vulnerable to abuse Titanium – strong/light Dull finish to reduce glare
13
Surgical Considerations
Leave protective covers on instrument tips until ready for use Leave instruments in holders with tips in the air Avoid catching tips on towels or other linens Handle each instrument individually Gently wipe each instrument after each use with lint-free gauze or non-fibrous sponge Place instruments in order of use for smooth flow
14
Surgical Considerations cont.
Place instrument in the physician’s hand in position of use Assist effectively, but never put hands in the surgical field unless requested to do so Do not touch microscope or lean against the OR bed Place foot pedal comfortably within physician’s reach Surgeon adjusts chair armrests, wrist-rest prior to scrubbing Adjust microscope prior to surgeon scrubbing, if possible
15
Instrument Care Clean and dry by hand No mechanical washing
Use soft bristled brush Clean and dry by hand No mechanical washing Lubricate and sterilize according to manufacturer Use specialized trays/holders with tip protectors
