Chapter 21: Minimally Invasive Surgery and Interventional Radiology

Vocabulary flashcards covering terminology and equipment for minimally invasive surgery and interventional radiology based on the lecture notes.

IR procedures

Procedures performed for diagnostic or therapeutic reasons that offer the patient a more cost-effective procedure with less risk, less pain, and less recovery time than open surgery.

IR procedure locations

Locations where IR procedures can be performed, including the hybrid OR, OR, patient's bedside, or cath lab.

Insufflation

In minimally invasive surgery, the inflation of the abdominal or thoracic cavity with carbon dioxide gas.

Pneumoperitoneum

The condition of the abdomen when it is distended with carbon dioxide gas.

Blunt trocar

A type of trocar that is rounded at the tip.

Intracorporeal

In MIS suturing and knot tying, a technique performed "inside the body."

Light source

A device that controls and emits light for delivery in endoscopic procedures.

Trocar

A sharp, rod-shaped instrument used to puncture the body wall.

Endocoupler

A device that connects the camera to the telescope.

Telescopic instruments

Long, narrow instruments with an optical lens used during endoscopic surgery.

Cannula

A hollow tube that holds the trocar.

Veress needle

A spring-loaded needle used to deliver carbon dioxide gas during insufflation.

Ligation loop

A suture or pretied loop used when a tissue structure requires ligation rather than suturing.

Light cable

A fiberoptic light cable that transmits light from the source to the endoscopic instrument.

Rigid lensed instrument

An instrument used in minimally invasive surgery, such as a rigid endoscope.

Endoscope

An instrument passed through a natural orifice for assessment or surgery of a hollow organ, duct, or vessel performed with a flexible, semirigid, or rigid version.

Instrument channel

The part of a flexible endoscope that receives biopsy forceps, brushes, and other instruments used to obtain specimens.

Control head

The component of a flexible endoscope that connects with the digital camera, optical system control handles, suction, and irrigation.

Air channel

The channel used to insufflate the lumen of the gastrointestinal tract to create space in the same way as a pneumoperitoneum.

Biopsy channel

The port located near the junction of the control head and insertion tube on a flexible endoscope.

Water channel

The channel used to clear blood and tissue debris from the lens.

Insertion tube

The component of the endoscope that enters the patient's body.
