1.0 INTRODUCTION
1.1 General Description
The OSI 6875 hana™ Surgery Table is designed to hold a patient undergoing the single incision, tissue
sparing Anterior Approach Total Hip Replacement and Total Knee Arthroplasty surgical procedures.
It is a stand-alone, single-pedestal, AC powered or internal battery operated table designed to position a
patient in a supine position during surgical procedures. The hana™ has three primary powered functions;
Height up/down, left/right lateral roll and Trendelenburg/Reverse Trendelenburg. Electromechanical
actuator-motors perform these motions which are controlled by means of a Hand Pendant with functions
clearly labeled. The table is also equipped with powered left and right Femur Lifts which are controlled by
a Foot Pedal providing the surgeon the ability to raise and lower the Femoral Hook during the Anterior
Approach Total Hip Arthroplasty.
Four (4) independent, manual caster floor locks are utilized to stabilize the table in the operating location.
An auxiliary control panel is provided for control of the table if the hand pendant is lost or becomes
disabled.

1.5 Glossary of Terms
The glossary of terms assumes the patient is supine with their head at the “Head-end of the Table”
(toward Control Panel) and their feet are at the “Foot-end of the Table” (toward Leg Spars). The Hand
Pendant functions are oriented for this position only.
“Head End of table” refers to the end of the table where the power cord, "ON/OFF" Power Switch, and
Control Panel are located; otherwise referred to as the “pedestal end”.
“Foot End of table” refers to the opposite end of the table also referred to the “leg spar end".
“Control Panel” is a panel of buttons and lights located on the back of the pedestal.
“Pedestal” refers to the main column structure that supports the tabletop.
“Left side of the table” refers to the table as you stand at the head end of table.
This also corresponds to the Hand Pendant button labeled “LEFT LATERAL ROLL”.
“Right side of the table” refers to the table as you stand at the head end of table.
This also corresponds to the Hand Pendant button labeled “RIGHT LATERAL ROLL”.
“Raise the table” refers to raising the height of the table.
This also corresponds to the Hand Pendant button labeled “HEIGHT UP”.
“Lower the table” refers to lowering the height of the table.
This also corresponds to the Hand Pendant button labeled “HEIGHT DOWN”.
“Trendelenburg” refers to lowering the height of the head-end of the table only. The corresponding
Hand Pendant button is labeled “TREN”.
“Reverse Trendelenburg” refers to raising the height of the head-end of the table only. The
corresponding Hand Pendant button is labeled “REV TREN”.
”Return to Level” or “Level the table” refers to returning the tabletop to a state of level regardless of
height. The corresponding Hand Pendant button is labeled “RETURN TO LEVEL”. Holding the “RETURN
TO LEVEL” button longer than approximately three seconds will also lower the tabletop to its lowest
position.
“Hospital Grade" outlet refers to a 120VAC outlet properly wired with earth ground: Neutral to Common
= 120VAC; Neutral to Ground = 120VAC; Common to Ground less than zero point five (0.5) VAC.
