Q

Light Cord

A
  • Accessory
  • Tight bundle of fiber optic strands
    of glass that transmits light into
    an enclosed space when
    connected to an endoscope.
  • Reduction of light conduction can
    results from broken fiber optics
    from being coiled too tightly or
    anything is allowed to crush it.

Q

Laparoscope

A
  • Viewing
    Size: Variable (5-10 mm) diameter, lens variable degrees
  • Endoscope placed through a trocar sleeve into the abdomen to view organs/tissues.
  • The outer edge of the scope is surrounded by light fibers that pass through the light cord and illuminate the abdomen. These fibers can be damaged if special care is not used with this scope. (can be one of the most expensive repairs.

Q

Veress Needle

A

Supply

Size: variable (regular or long)

  • Introduces CO2 gas into the abdomen to distend the abdominal cavity allowing visibility by pushing the abdominal wall away from the organs during laparoscopic procedures. (pneumoperitoneum)
  • it is put in at the initial incision then inflates to 12-15mmhg then removed.

Q

Insuflation Tubing

A

Supply

  • This tubing is attached to a
    CO2 gas pump then connected to veries needle and remove sleeve ( kept throughout the procedure.
  • The tubing has an inline filter
    to reduce contaminants that
    may enter the surgical site.
    This filter end should be
    passed off to the circulator

Q

Trocar with Sleeve

A

Supply/Retracting/Viewing/Cutting

Size: Variable (5, 10 and 12 mm)
DIFF styles etc blade, non blade, etccc

Sleeve provides a leak free seal (retains CO2 gas when instruments are placed/removed) that protects the skin and tissue layers from
damage sustained while manipulating or introducing instrumentation.

Trocar: Used to dissect through abdominal tissue (after small skin incision is made) to provide access to the abdominal cavity during endoscopic procedures

Q

Trocar Anchoring System

A

Supply

Sutures are placed on both sides of the sleeve and wrapped around the anchor to seal it against the abdominal wall and then insufflation is introduced.

  • Used in open technique when a blunt trocar with an anchor is inserted without the prior use of pneumoperitoneum through a small incision in the fascia layer.

Reducer cap

A
  • Supply
  • This devise clips on the top of a 12 mm or 10 mm trocar sleeve allowing 5 mm instruments to be used in larger ports without loosing pressure in the pneumoperitoneum.

Hook Scissors

A
  • Cutting/Dissecting

Endoshear Scissor

A
  • Cutting/Dissecting

Size: Variable (5mm or 10mm)

Q

Bullet Tipped Grasper

A
  • Grasping/Holding
  • Atraumatic: common grasper used on most tissue types.
  • It is named for its tip which is shaped like a bullet.

Q

Maryland Dissector

A
  • Grasping/Holding/Dissecting
  • Atraumatic: Used similarly as a debakey would be in an open case.
  • The fine curved tip is used for blunt dissection of fatty or thin tissue (omentum, mesentery, connective tissue).
17
Q

Aggressive Toothed Grasper

A
  • Grasping/Holding

Size: Variable (5mm or 10mm)

  • Traumatic: used to hold tissue that will be removed. Be sure the surgeon is aware the grasper has teeth when it is handed to him
  • Commonly used to remove the slippery gallbladder
18
Q

Endoscopic Allis Clamp

A
  • Grasping/Holding
  • Traumatic: Used to firmly hold moderate
    strength tissue or tissue that is being
    removed.
19
Q

Endoscopic Babcock

A
  • Grasping/Holding
  • Atraumatic: Used for grasping fragile tissues
  • Just like the conventional babcock clamp, it grasps bowel, appendix, stomach, and fallopian tubes safely.
20
Q

Olson Clamp

A

Grasping/Holding

  • Atraumatic: Used during a Laparoscopic Cholecystectomy in conjunction with a Taut catheter and radiographic dye in a syringe
  • The Taut catheter is loaded into the lumen of the handle of the clamp, and then the syringe
    of dye is connected to the catheter. The cystic duct is clamped closed with a staple proximal
    to the gallbladder. Next a tiny nick is made below the staple and the Taut catheter is
    introduced into the duct and advanced a short distance. The jaws of the Olson clamp are
    then locked shut, compressing the duct. Next the surgeon injects radiographic dye into the
    duct. Any stones blocking the duct will appear in x-ray, telling the surgeon if further
    exploration will be required.
21
Q

Endoscopic biopsy punch

A
  • Cutting
  • Traumatic: Used to remove a bite of tissue to
    be sent as a specimen to pathology.
22
Q

Blunt Probe

A
  • Retracting/Viewing/Probing
  • Atraumatic: Used to manipulate tissue while
    exploring the abdomen and pelvis
23
Q

Needle Aspirator

A
  • Suctioning
  • Traumatic: This devise is used to collapse fluid filled cysts or possibly the gallbladder. The leur lock end of this tube is attached to suction or a large syringe. The needle end is then used to puncture the sack and the liquid contents are evacuated.
24
Q

Suction Bovie

A
  • Suctioning/Occluding
  • This instrument will be attached to suction at its leur lock end and to an electrical cord at the metal prong. It is then plugged into a bovie machine and operated by the surgeon
    using a foot pedal. This allows the surgeon to evacuate bovie smoke from the field as it is produced.
25
Q

Hook Bovie

A
  • Occluding/Cutting

Comes in L hook and J hook varieties.

  • This bovie has a hook on the end to allow the surgeon to hook around tissue and cut through it using electrical current. This current is activated by pressing on a foot
    pedal when needed.
26
Q

Endo Catch

A

Supply

  • Single use specimen pouch used to retrieve a specimen and remove it through a 10-12mm sleeve while containing contents securely during retrieval process.
  • Once contents are placed into the pouch the ring on the end is pulled. This “purse strings” the pouch closed.
27
Q

Laparoscopic Fan Retractor

A
  • Retracting/viewing
  • Atraumatic: Used to bluntly retract the liver or other broad organs.
  • The dial at the bottom widens the fingers to create the broad fan.
28
Q

Endoscopic Kitner/Peanut/Cherry

A
  • Supply
  • Blunt (intentional tearing of tissue)
    laparoscopic dissection in small areas.
29
Q

Anti-Fog

A

supply

Anti-fog should be allowed to completely dry on the tip of the scope for full effectiveness (don’t wipe it off with a sponge after application).

  • Used on the tip of scopes to prevent fogging when a cold scope is placed
    in a warm body
30
Q

Scope Warmer

A
  • Supply
  • Used to warm the tips of scopes to prevent fogging when a cold scope is placed in a warm body
  • Heat activation varies per device
