1General information
1.1 Indications
Morcellator set for morcellation and extraction of tissue and for removing myomas or the uterus during laparoscopic pro-
cedures in gynecology.
1.2 Principle
The ERGO  - Morcellator is a control unit for the Nouvag Morcellator for use in morcellation and extraction of tissue
as well as for myoma removal at laparoscopic interventions. A rotating cylindrical tube with a blade at the distal end is
inserted through an abdominal cavity that has been enlarged by an Insufflator. The tissue that is to be removed is guided to
the cutting tube by a gripper, cut off and removed through the tube.
This manual describes three different options for removing tissue by a laparoscopic procedure.
Option 1: Tissue removal by morcellation with protective tube
Instruments (gripper) are inserted through a protective tube sealed by a valve system. The valve can be covered by a thumb
for removing the gripper from the sealed protective tube to prevent gas loss.
Option 2: Tissue removal by morcellation with Trocar Cannula
Instruments (cutter tube, gripper) are inserted through the Trocar Cannula. The Trocar Cannula contains a valve that pre-
vents gas loss when withdrawing the instruments.
Option 3: Tissue removal (myomectomy) with myoma drill through the Trocar Cannula
Insertion of the myoma drill through the Trocar Cannula (Ø  mm) with separate access. Removal of tissue by the Morcel-
lator with grasping forceps according to option  or .
For a myomectomy only the Trocar Cannula (REF nou) with a diameter of  mm may be used in connection with the
myoma drill.
1.3 Contraindications
Relative or absolute contraindications may result from the general medical findings or in special cases in
which the patient’s risk for motor-driven tools is significantly increased. Ovaries, fallopian tubes, myomata
and other structures must be devascularized and dissected before morcellation.
The laparoscopic deployment of morcellators is contraindicated:
• for treatment of malignant tumors
• for treatment of vascularized tissue
• for preparation of tissue
• in gynecologic surgery in which tissue to be morcellated is known or suspected to contain malignacy
• for removal of uterine tissue containing fibroids in patients who are:
• Peri or postmenopausal, or
• Candidates for en bloc tissue removal, for example through the vagina or via a mini-laparotomy incision.
• Cases described in the literature, must be observed.
1.4 Target group
Younger women between  and  years of age. From the age of , the risk is increased, but an operation by morcellation
is still possible.

bear the following information in mind:
Every use of the ERGO  - Morcellator different to the product description defined in chapter “Intended use and oper-
ation”, causes risks for patients and trained personnel. If physical examinations and therapies are carried out without use
of the devices then the devices must be removed from the place of treatment. Avoid any connection or close adjacency to
other devices.
3.1 EMC, Manufacturer’s Declaration of Conformity
The use of (RF) Radio Frequency emitting devices and equipment as well as the occurrence of negative environmental
factors in the close area of the ERGO  - Morcellator may cause unexpected or adverse operation. The connection or the
placing of other devices in close vicinity is not allowed.
The EMISSIONS characteristics of this equipment make it suitable for use in industrial areas and hospitals (CISPR  class
A). If it is used in a residential environment (for which CISPR  class B is normally required) this equipment might not offer
adequate protection to radio-frequency communication services. The user might need to take mitigation measures, such as
relocating or re-orienting the equipment.
Use only accessories and cables as specified in the product description. Further observe the EMC manufacturers declara-
tion of conformity.

3.4 Essential requirements
Before using the ERGO 300 - Morcellator, this
instruction manual must be read thoroughly and
you must be well acquainted with the functions
and handling of the unit.
The products described in this manual must be
used by trained and qualified medical personnel
only in accordance with the requirements and
with reference to the manual.
For protection of the patient, the user and third
parties the products used must be prepared as
specified in the manual.
Improper use or repair of the device, or failure to
observe these instructions, will relieve us from
any obligation arising from warranty provisions or
other claims.
The use of third-party products is the
responsibility of the operator. Functionality and
patient safety cannot be guaranteed with third-
party accessories.
Prior to using the device, before startup,
and before operation, the user must always
ensure that the device and accessories are in
good working order and are clean, sterile and
operational.
Repairs may only be performed by authorized
NOUVAG service technicians.
Only use NouvaClean and NouvaOil spray to
care for the gear unit. For the electronic motor
use only NouvaOil spray. The use of other care
products can lead to malfunctions and void the
guarantee.
Uterine tissue may contain unsuspected cancerous tissue. The use of laparoscopic, motor-driven morcellators in
hysterectomy and myomectomy, carries the risk of spreading cancerous tissue beyond the uterus, thereby reducing long-
term patient survival. This information should be communicated to patients in advance of surgery when the use of motor-
driven morcellators is being considered.
3.5 During use
The device is not sterile on delivery. All sterilizable
parts must be sterilized before use (see Chapter 
Instrument preparation).
Never operate the clamping mechanisms of the
cutting tubes while the system is running. This
could result in instrument damage.
Operate the device only outside the danger zone
of explosive, flammable mixtures or gases.
Keep hands clear of the cutting tubes when
operating the device. Danger of serious injury.
The motor ventilation slots must be kept clear in
order to prevent the motor from overheating.
The ERGO  - Morcellator must be operated
under the continuous supervision of medically
qualified persons only.
The risks and benefits of using recovery pouches
when using motor-driven morcellators in
laparoscopic procedures remain to be determined
and established.
Make sure that the operating voltage matches the
mains voltage.
Disregarding the guidelines on intermittent
operation ( min on,  min o for 8 cycles) may
cause burns at contact with the gear unit.

5 Before use
The ERGO  – Morcellator and all required accessories and instruments must be placed on a level nonslip surface. Do
not allow the operating range of the device with cable to be restricted by limiting factors. The display, keypad and indicator
lights must be fully visible at all times.
It is very important to ensure that no objects can fall on the pedal. The power plug at the rear of the device must be acces-
sible at all times.
5.1 Potential equalization connection according to DIN 42801
At the back of the device a potential equalization plug is installed, according to DIN .
The additional potential equalization has the task of equalizing potentials between different parts of conduc-tive materials
that can be touched at the same time, or reducing potential differences.
This connection must be used, to protect the patient, the user and third parties from touch voltages.
The equipotential plug is marked with the following symbol:
5.2 Connection to the power supply
• Before plugging the power cable into the power socket for the first time, you must check the supply voltage setting
next to the power switch.
• In order to prevent the risk of electric shock, the device may only be connected to a power network with a

• Check that Morcellator is correctly assembled.
• Check that the gear unit runs smoothly; if necessary treat it with NouvaOil care spray.
• Check that the motor is clean and runs smoothly; if necessary clean it and treat with NouvaOil care spray.
• Repeat the function check.
Risk of injury by motor failure
Problem: the motor becomes very hot. Cause: the motor was damaged during preparation.
Remedy: do not continue to use the motor. Always have a spare motor available.
5.3.2 Assembly of the Morcellator set with Trocar Cannula (according to option 2)
Using the Trocar Cannula
The Trocar Cannula is used instead of the protective tube. The integrated valve flap prevents the escape of gas when
instruments are moved in and out.
The nose of the Trocar Cannula partially extends beyond the cutter tube to protect organs in the abdominal cavity from
the sharp blade. This requires the Morcellator to be rotated under visual supervision (endoscopy) so the nose of the Tro-
car Cannula covers the cutter tube blade to protect the organ.
1. Visual check
• Check the product for sealing, corrosion and sterility.
• Ensure that it is free from rust, dents and scratches.
• The distal end of the Obturator must not be damaged.
• The sealing flap and the seal must not be damaged.
Risk of injury
Select blade. Make sure that the cutting edge of the blade is sharp and undamaged (e.g. no cracks or burrs).
