Endoscopes Flashcards
(41 cards)
What is endoscopic surgery?
Minimally invasive surgery
- small incisions
- computer assisted
- digitak imaging/data
Endoscopes can be rigid or flexible for visualizing the interior of a hollow organ or part for diagnostics and surgical purposes
Has channels to enable passage of instruments
Benefits to endoscopic surgery?
Decrease risk of SSI Fast recovery Decrease post op pain Decrease tissue trauma Decrease blood loss Short stays Decrease adhesions
Bioburden?
The number of viable organisms contaminating an object
Biofilm?
Accumulated biomass of bacertia and extra cellular material that is tightly adhered to a surface
Difficult to remove
What is borescope?
A device used to inspect the inside of an instrument through a small opening or lumen of the instrument
What is extravasation?
To pass by infiltration of effusion from a vessel or channel into surrounding tissue
Edema, abd distension, intra abd compartment syndrome
High level disinfection?
Processes that kill all microbial pathogens but not necessarily all bacterial spores
What is insufflation?
The act of blowing gas into a cavity for the purpose of visual examination
What is larparoscopic surgery?
Minimally invasive surgery
- port site
- instruments inserted to perform surgery
Laparoscope is inserted through an incision in abdominal wall and used to visually examine the interior of peritoneal cavity
What is a mechanical processor?
Mechanically cleans, rinses and exposes flexible endoscopes and accessories to a high level disinfectant or liquid chemical sterilant
What is covered under minimally invasive surgery?
Surgeries performed one or more small incisions Radiographic and MRI Computer assisted devices Robotics And other technologies
What is a port site?
A small incision that a trocar is inserted for placement of cannula into a body cavity or body part
What is pneumoperitoneum?
The presence of air or gas within the peritoneal cavity of abd
What is a no fly zone?
Area for safe use of imaging and other equipment
No staff should in area
Safety precaution
What is sterilization?
Processes by which all microbial life are killed
Pathogenic, nonpathogenic and spores
What do video towers contain?
Video monitor Light source Camera control Suction or insufflation Suction irrigation system Esu Gas cylinders Devices for recording
What does white balance do?
Adjusts white, red, green and blue colours to appear as natural as possible
Hold camera 2 inch away from surface and press white balance button
Recording systems for endoscopes?
Must follow HIPPA for storage
Can take pics, store data and print/transfer data
What is an endoscope?
A tube inserted into a natural body orifice or through a small incision to access organs/structures
Rigid or flexible
Surgical or diagnostic
External light for endoscopic surgery?
Requires to visualize
Fiberoptic light = ignition source
*fire safety
Components: light source, cable with light at end and inserted into channel
Fire safety for light source?
No contact with pstient skin or flammable material
Do not rest on drapes
Turn off or place in standby
What are trocars?
Access operative site
Consists of:
obturator - sits inside cannula snd created orifice and removed
Cannula - hollow cylinder that surgical instruments are places through
What are dissecting instruments?
Scissors
- blunt or sharp
- straight or curved
- may connect to ESU to coag
- round tip to dissect w/o truma
Maryland
- seperare/divides tissue
- different shapes to spread, divide, grasp, retract, coag
Clamping instruments?
Dolphin grasper
Toothed grasper
Cup forceps
- traumatic = teeth
- atraumatic = smooth, serrated jaw
- biopsy = used for tissue collection
