1.2 General Description

The Mizuho OSI 6875 hana® Surgery Table is designed to safely hold in proper position a
patient undergoing orthopedic surgical procedures including supine position for the anterior
approach for Total Hip Arthroplasty, Total Knee Arthroplasty, IM Nailing of the Femur or Tibia
and Hip Pinning, and Lateral position for IM Nailing of the Femur.

It is a stand-alone, single-pedestal, AC powered or internal battery powered table designed
to position a patient in a supine or lateral position during surgical procedures.

The table has a 2” (5 cm) MIZUHO OSI Tempur-Pedic® pad. The TEMPUR® used in the
manufacture of MIZUHO OSI pads has viscoelastic properties and is a temperature sensitive
material, becoming softer where the patient’s body is making the most contact with the
surface and remaining firm in areas where less body contact is being made. Pressure is
distributed evenly over the entire surface area. The pad is radiolucent, MR safe and latex
free. The benefits of using MIZUHO OSI Tempur-Pedic® are improved pressure
management, reduced shear forces and enhanced patient comfort.

The hana® Surgery Table has three primary electrically 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 or onboard
auxiliary control panel with functions clearly labeled. The table is also equipped with
powered left and right femur lifts that 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.

6.5 Battery System

The 6875 hana® Surgery Table is equipped with a battery system that provides power to all
functions, and consists of two batteries (NV0801). Due to the relatively low power
consumption of the 6875 hana® Surgery Table, the table can be used on battery power for up
to 12 hours at 10% duty cycle.

WARNING:

This symbol indicates an external ground stud that is required for use when the
AC power cable is not connected to a protective earth ground hospital grade AC outlet
in your operating room or facility.

To protect the patient, hospital staff and the table from possible electrical hazards, an
external ground wire connection is required between the external ground stud and
protective earth ground.

Battery charge status is shown via a LED on the hand pendant labeled battery status and in
the power indicator section of the control panel.

On the hand pendant:

 If illuminated green = OK.
 If illuminated red = charge required

If a recharge is required, charging the batteries is necessary for a minimum of 3 hours. Fully
discharged batteries will require 18 hours for a complete charge. To charge the batteries,
simply plug the power cord into an appropriate hospital grade AC outlet and turn the power
switch on. It is important to plug in the table as soon as possible after the battery status LED
is illuminated red.

MIZUHOSI 2009 19 NW0508 Rev. D

WARNING:
Life of the batteries can be shortened if the table remains unplugged and turned on for
extended period of time with the red battery charge light illuminated. While in storage
it is desirable that the table be plugged in and the power switch turned on so that the
batteries remain charged. If this is not possible, the batteries must be charged for at
least three hours per week under normal use conditions. This can be accomplished
when using the table under AC power since the system batteries are automatically
charged while the table is plugged in and turned on.

Both batteries should be replaced every five (5) years or when they fail to hold a charge.

6.6 Troubleshooting

In the event of a table malfunction:

 Check input power, verify the power cord is plugged into a live hospital grade AC

electrical outlet.

 Verify the power switch is on; the switch illuminates green.
 Check hand pendant is plugged in and lights illuminated.
 Switch main power to off, wait 30 seconds and turn to on position.
 Contact Mizuho OSI Customer Resource Group if table function is not restored, please

note what functions are working as well as those not working when you call (see section

13.0 of this manual for more information on Customer Resource Group).

7.0 CLEANING AND MAINTENANCE

7.1 Cleaning And Disinfecting

NOTE: Never pour any liquid directly onto the table. Never subject the 6875 hana® Surgery
Table to an equipment washing machine.

Use of iodophors will cause staining.

Table exterior:

The exterior surface should be regularly wiped clean with a mild detergent solution and
wiped dry with a soft lint-free cloth. This includes the table pad and table top.

Care should be taken to avoid exposing the table to excessive moisture. Flooding, fogging
or steam cleaning is not recommended.

Blood or other fluids, etc., if allowed to remain on the table for a long period of time, will
require special cleaning to remove. A 5% acetic acid solution or white vinegar and water
solution is especially good for this purpose.

Clean with a good commercial cleaning compound, such as Stainless Steel Magic or Acme
White Finish, and then buff the surface by hand to correct staining and discoloration of plated
or stainless steel surfaces only.

To disinfect exterior surfaces, use a quaternary ammonium compound or similar type
disinfectant compound according to manufacturer's directions for use. Wipe dry with a soft
lint-free cloth.

NOTE: Failure to thoroughly dry the surface after cleaning and disinfecting may result in
rust.

Table Pad:

®

MIZUHO OSI

Tempur-med® Pad

IMPORTANT: The MIZUHO OSI Tempur-Pedic

®

pad should always be stored in a flat
position. It can actually get stiff in cold temperatures and can crack and
break if in a rolled position. It is important that you allow the pad to warm to
room temperature before attempting to utilize or handle it.

When handling always grasp by the entire thickness of the pad.

Do not lift, slide or carry MIZUHO OSI Tempur-med

®

pads by grabbing the fabric. The cover

may tear or rip.

The pad is intended to be cleaned in place. It does not need to be rotated or flipped.

rinse per manufacturer’s label instructions. Wipe dry with a lint free cloth. Do not soak or

MIZUHOSI 2009 21 NW0508 Rev. D

autoclave pads. The continued use of bleach or highly concentrated chemicals will void the
warranty on the cover.

When cleaning the bottom of the pad or the table top, simply lift one end of the pad, and fold
it over onto the other end. Clean the pad or the table top then return to pad to flat on the
table top.

7.2 Preventative Maintenance

1.0 INTRODUCCIÓN

1.1 Avis os importantes

Precaución:
Para garantizar el uso seguro del equipo, LEA ESTAS INSTRUCCIONES EN SU TOTALIDAD
y conserve el manual en un lugar accesible para consultas posteriores.

Obedezca y siga todas las advertencias, precauciones e instrucciones indicadas en el equipo o
descritas en este manual.

En este manual, el símbolo de ADVERTENCIA alerta al usuario de la presencia de
instrucciones importantes p ara el funcionamie nto, el man tenimiento o la s eguridad .

Protección contra el riesgo de descargas eléctricas:

El símbolo indica que este equipo está clasificado como parte aplicada de TIPO B, en
conformidad con la norma CEI 60601-1, y es apto, en general, para las aplicaciones que
impliquen contacto con partes externas o internas del paciente, excepto el corazón. El circuito
del paciente está conectado a una toma de tierra de protección y este equipo debe conectarse
sólo a enchufes con toma de tierra.

Este símbolo indica que, cuando el cable de alimentación no está enchufado en el
quirófano o en el centro hospitalario a un enchufe con toma de tierra protectora, se requiere un
terminal de tierra externo.

Para proteger al paciente, al personal del hospital y a la mesa de posibles peligros, se requiere
una conexión externa mediante un conductor de tierra entre el terminal de tierra externo y la
toma de tierra protectora.

ADVERTENCIA:

Si existe alguna duda sobre la integridad de la fuente de alimentación de red, será
necesario operar el equipo haciendo uso de su fuente de alimentación eléctrica interna
(baterías).

ADVERTENCIA:
Para prevenir la estasis y la acumulación venosa, así como la aparición de úlceras por
compresión, de neuropatías, hipertensión, hipotermia o una derivación indebida a tierra
durante la electrocirugía tisular, deben seguirse los procedimientos preoperatorios e
intraoperatorios adecuados.

NOTA: En estas instrucciones se describen las técnicas de aplicación sugeridas por el

1.2 Descripción general

La mesa quirúrgica hana® 6875 de Mizuho OSI está diseñada para sujetar en la posición
adecuada a pacientes sometidos a diversos procedimientos de cirugía ortopédica, entre ellas,
en la posición supina para el abordaje anterior de artroplastia total de cadera, artroplastia total
de rodilla, enclavado intramedular femoral o tibial y enclavijamiento de la cadera (pinning), y en
la posición lateral para enclavado intramedular femoral.

Se trata de una mesa autónoma, con una sola columna base, que funciona con corriente
alterna o con batería interna, y diseñada para colocar al paciente en posición supina o lateral
durante intervenciones quirúrgicas.

La mesa tiene una colchoneta MIZUHO OSI Tempur-Pedic® de 5 cm (2 pulgadas). El
TEMPUR® empleado en la fabricación de las colchonetas MIZUHO OSI® tiene propiedades
viscoelásticas y es un material sensible a la temperatura, que se hace más blando en los
lugares en los que el cuerpo del paciente está más en contacto con la superficie y permanece
firme en las zonas en las que hay menos contacto con el cuerpo. La presión se distribuye de
forma regular sobre toda la superficie. La colchoneta es radiolúcida, segura para la RM y no
contiene látex. Las ventajas del uso de la MIZUHO OSI Tempur-Pedic® son: una mejor
distribución de la presión, una reducción de las fuerzas de cizallamiento y una mayor
comodidad del paciente.

La mesa quirúrgica hana® presenta tres funciones motorizadas principales: subida/bajada,
inclinación lateral a la izquierda/derecha y Trendelenburg/Trendelenburg inverso. Los motores
accionadores electromecánicos realizan estos movimientos que se controlan mediante un
mando de mano o un panel de control auxiliar en la mesa con las funciones claramente
marcadas. La mesa también está equipada con elevación motorizada para el fémur derecho e
izquierdo que se controla con un pedal, lo que proporciona al cirujano la posibilidad de subir y
bajar el gancho femoral durante el abordaje anterior de la artroplastia total de cadera.

Los cuatro (4) frenos de suelo manuales e independientes para las ruedas giratorias sirven
para estabilizar la mesa en el lugar de la intervención.

3.3 Traslado de la me sa

Una vez desactivados los cuatro (4) frenos de suelo, la mesa puede moverse sobre las ruedas
a un nuevo lugar. Lo mejor es llevar la mesa con el piecero por delante. La mesa hana® 6875
es muy pesada y se necesitan como mínimo dos personas para moverla, una situada en el
cabecero y la otra en el piecero; además, deberán tomarse medidas para controlarla mientras
rueda.

ADVERTENCIA:
Si se permite que la mesa ruede a demasiada velocidad, podría resultar difícil pararla o
girarla. El choque de la mesa con un objeto estacionario podría causar daños graves al
tablero. Si un choque tiene lugar, se debe inspeccionar la mesa visualmente para
detectar daños y se debe realizar una comprobación de funciones (consulte el apartado

5.0 de este manual). Si descubre un daño o la mesa no supera la prueba de
comprobación de funciones, llame al representante del servicio técnico de Mizuho OSI.

3.4 Funcionamiento del mando de mano/panel de control

La mesa quirúrgica hana® 6875 se controla mediante un mando de mano, como control
alternativo, o mediante el panel de control incorporado en el suministro de corriente. El mando
de mano se enchufa en el conector hembra HAND PENDANT (mando de mano) en el panel de
control (consulte figura 3). Pulse y mantenga pulsado el botón correspondiente a una de las
funciones en el mando de mano hasta lograr la posición deseada.

En el mando de mano se encuentra el botón RETURN TO LEVEL. Este funciona de modo que
lo primero que se nivela es la inclinación lateral (lateral roll), después trendelenburg,
posteriormente se vuelve a nivelar la inclinación lateral y por último, mueve la mesa a su
posición más baja. Se ha programado una demora de 3 segundos tras la finalización de la
funciones de nivelación antes de volver a su posición más baja. Para llevar la mesa a la
posición final, es necesario mantener pulsado este botón y no soltarlo hasta que la mesa se
pare. El controlador considera que la mesa está nivelada si está dentro de un margen de ± 2°
del nivel cero. Si el botón para nivelar se pulsa mientras la mesa está en este intervalo, la mesa
no se moverá. Si se necesita aproximar más la posición de la mesa a 0°, pulse el botón de
función adecuado en el mando de mano hasta que se logre la posición deseada.

6.0 EL SISTEMA ELÉCTRICO

6.1 Descripción

El sistema eléctrico permite controlar todas las funciones de la mesa y está integrado por los
siguientes elementos: un cable de alimentación, un interruptor-disyuntor eléctrico, arneses de
cables, una fuente de alimentación, un circuito controlador, un mando de mano, gatos de
tornillo-accionadores de frenos de suelo y varios accionadores electromecánicos. Los
accionadores eléctricos motorizados de tornillo regulador manipulan las funciones de altura,
inclinación lateral, frenos de suelo y Trendelenburg de la mesa. Los requisitos de corriente de
entrada son 100 V~ 50/60Hz, 4 A, 120 V~ 60Hz, 4 A o 230 V~ 50Hz, 2 A, con un ciclo de
trabajo del 10%/6 minutos como se indica en la etiqueta del número de serie. Remítase al
diagrama de conexiones eléctricas de la mesa quirúrgica hana® 6875 en el apartado 11.2 para
obtener más detalles del sistema eléctrico.

Los componentes principales del sistema de control eléctrico se encuentran en la caja de
alimentación eléctrica en el cabecero de la mesa.

6.2 Interruptor de alimentación

En el cabecero de la mesa hay un interruptor de alimentación y disyuntor que se ilumina.
Cuando está iluminado, indica que la mesa está enchufada en un enchufe eléctrico con
corriente de la red y encendida. (Cuando la mesa funciona con batería, este interruptor no se
ilumina.) Dicho interruptor hace también las veces de disyuntor. En el caso de producirse una
sobrecarga, el interruptor salta automáticamente. Para realizar una reposición, pulse a la
posición de apagado y luego de nuevo a la de encendido.

6.3 Disyuntores para componentes

El sistema eléctrico incluye disyuntores automáticos de 24 VDC para componentes
individuales, situados en el cabecero de la mesa. Si se produce un cortocircuito en el circuito de
bajo voltaje, el disyuntor salta, lo cual queda indicado por un botón que sobresale del orificio de
acceso. Para realizar una reposición, pulse el botón hacia adentro y suéltelo.

ADVERTENCIA:
Antes de realizar la reposición, averigüe el origen de la sobrecarga. Si no logra averiguar
y reparar el origen del fallo eléctrico, póngase en contacto con Mizuho OSI para recibir
asistencia.

MIZUHOSI 2009 NW0508 Rev. D

6.5 Sistema de baterías

La mesa quirúrgica hana® 6875 está equipada con un sistema de baterías que suministra
corriente a todas las funciones y consta de dos baterías (NV0801). Debido al consumo
relativamente bajo de energía de la mesa quirúrgica hana® 6875, ésta puede utilizarse con
alimentación por batería hasta 12 horas con un ciclo de trabajo del 10%.

ADVERTENCIA:

Este símbolo indica que, cuando el cable de alimentación no está enchufado en el
quirófano o en el centro hospitalario a un enchufe de grado hospitalario con toma de
tierra protectora, se requiere un terminal de tierra externo.

Para proteger al paciente, al personal del hospital y a la mesa de posibles peligros, se
requiere una conexión externa mediante un conductor de tierra entre el terminal de tierra
externo y la toma de tierra protectora.

El estado de carga de las baterías se muestra con un LED en el mando de mano llamado
Battery Status y en la sección de alimentación del panel de control.

En el mando de mano

 Si está iluminado en verde = en buen estado.
 Si está iluminado en rojo = cargar.

Si se precisa recarga, cargue las baterías durante un mínimo de 3 horas. La carga completa de
baterías totalmente descargadas requiere 18 horas. Para cargar las baterías, simplemente
enchufe el cable de alimentación en un enchufe de grado hospitalario adecuado y encienda el
interruptor de alimentación. Es importante enchufar la mesa a la red de corriente tan pronto
como sea posible una vez que el indicador LED de estado de las baterías se ilumine en rojo.

MIZUHOSI 2009 NW0508 Rev. D

21

ADVERTENCIA:
La vida útil de las baterías puede verse reducida si la mesa no está enchufada a una
toma de corriente pero se mantiene encendida durante un tiempo prolongado con la luz
roja de carga de baterías encendida. Mientras esté almacenada, conviene que la mesa
esté enchufada y encendida para mantener las baterías cargadas. Si esto no es posible,
bajo unas condiciones de uso normales, es necesario cargar las baterías como mínimo
tres horas cada semana. Esto puede realizarse mientras se utiliza la mesa con la
corriente de la red, ya que las baterías se cargan automáticamente mientras la mesa está
enchufada a la red y el interruptor está encendido.

Las dos baterías deben cambiarse cada cinco (5) años o cuando ya no acumulen bien la carga.

6.6 Solución de problemas

En caso de avería:

 Compruebe la corriente de entrada, asegúrese de que el cable de alimentación esté

conectado a una toma de corriente de red de grado hospitalario que funcione.

 Compruebe que el interruptor de alimentación de la mesa esté encendido; se ilumina en

verde.

 Compruebe que el mando de mano esté enchufado y las luces iluminadas.
 Apague el interruptor de corriente principal, espere 30 segundos y vuelva a encenderlo.
 Póngase en contacto con el Grupo de Recursos para el Cliente de Mizuho OSI si no logra

recuperar las funciones de la mesa, asegurándose de, antes de llamar, anotar las funciones
que no funcionan así como aquellas que lo hacen (consulte el apartado 13.0 de este
