MIRUS CIRCULAR STAPLER

MIRUS^TM Circular Stapler has applications throughout the alimentary tract for the creation of end-to-end, end-to-side and side-to-side anastomosis in both open and endoscopic surgeries. The design offers adequate lumen with a series of cutting diameters from 12mm to 22mm. The adjustable staple height technology assures minimal tissue tension and controlled compression besides a reliable tactile and audible feedback while firing.

MIRUS^TM Circular Stapler is available in conventional 2 row and the new 3 row staple line design. The 3 row design deploys an additional third row of staples offering wound security and adequate hemostasis.

Advantages of MIRUS in anastomosis

• It offers the best in class "B" shape staple formation & cutting with precision which ensures better security and superior hemostasis.
• MIRUS Circular Staplers have application throughout the alimentary tract for end-to-end & end-to-side anastomosis.
• II rows for secure heamostasis & III rows for better security & superior hemostasis.
• Sizes available : 2 row: 24,25,26,29,32
  3 row: 21,24, 25, 26, 29, 31,32

Available in II and III Rows model MIRUS

• It has stainless steel anvil shaft with longer purse tying area.
• Tissue compression gauge (Staple compression gauge) is provided to ensure the accurate staple formation & which suits to variable tissue thickness.
• Wing nut like shape of rotating knob is provided for proper rotation and dexterity while opeining and closing anvil.
• The audible & tactile feedback (clicking sound) is better as compared to others.

Mirus Circular Stapler – Instrument

Disease Area: Rectum

Procedure Steps:

• Access through separation of GI layers
• Identification and mobilization of malignant area
• Transection, Resection & Anastomosis

Open Mirus circular stapler with the help of black rotating knob available at the proximal end and disengage the anvil to expose the trocar & then close it. Ensures that trocar goes completely inside the housing during closing. Take anvil & purse string at proximal end of lumen and ensure that it should be tight properly.

Insert the circular stapler in anal canal & ensures that it reaches to the closed end of distal lumen. Then again open the circular stapler with the help of black rotating knob. Ensures that circular stapler advancing the trocar & pierce above & below the staple line of rectum. It should not go through the staple line. Then fully advance the trocar with the help of rotating knob.

Ensures that the orange indicator is visible inside the abdominal cavity & outside the staple line. Rotate the knob & close circular stapler slowly till rotation motion is halted. Observe the tissue compression indicator available on the top of circular stapler. Red marking should be in or below green zone (only then you will be able to open the red safety).

Wait for 30 secs so that the tissue will extrude out & tissue becomes dry. Open red safety lock. Now fire the circular stapler with 2 hands on a single fluid motion. Full squeeze is compulsory (100% squeeze). Release the handle & engage red safety back to original position. Open the instrument by turning the Wing Nut counterclockwise as indicated on the end of the knob. For easy removal, only open the instrument one-half to three-quarters revolutions. Remove circular stapler from anal canal with fish tale movement. Check the 2 donuts (both proximal & distal side).
