Neo Pedicle Screw System™ – Ratcheting devices (Screwdriver and components)
Instructions for use and processing (cleaning, disinfection, and
sterilization)
PURPOSE
The Neo Pedicle Screw System™ is intended to help provide immobilization,
correction and stabilization of spinal segments as an adjunct to fusion of the
thoracic, lumbar, and/or sacral spine. In adjunction to the standards
instruments provided as single use sterile, Neo Medical provides Ratcheting
devices which are intended to ease the surgeon gesture, reduce tiredness of
tightening screws, and help keeping the appropriate trajectory when tightening
screws. The ratcheting devices include a ratchet screwdriver which is intended
for being used with ratchet handles and adaptors for the steps of inserting
the pedicle screws. The ratchet screwdriver allows firm connection between the
pedicle screws, the screw extender and the screwdriver, avoiding any toggling
of the screws.
This instructions leaflet provides information for use of the ratcheting
devices (Section A) and for their proper processing before first use and after
each subsequent use (Section B).
DESCRIPTION
The Neo Pedicle Screw System™ is mainly used with single use sterile
instruments which are described in the system’s instructions for use. The
procedure for use is described in the surgical technique. The ratcheting
devices are provided by Neo Medical as non-sterile and are intended to be re-
used after appropriate cleaning, disinfection and sterilization procedure.

USE OF RATCHETING DEVICES
Two series of devices are provided in order to implement the ratcheting
function with the Neo Pedicle Screw System™.
The first series is for use with the single use screwdriver.
The corresponding devices are the following:
- Single use screwdriver provided in the Pedicle Screw instrument kit
- 3 Screwdriver Adaptors with different connection bit types: Hudson Modified, 1/4”, and Big AO
- 2 Ratchet handles of the corresponding type
Assembly preferred order:
- Ratchet handle on the Adaptor
- Ratchet handle & Adaptor on the single use screwdriver
The second series is for use with a reusable screwdriver also intended to reduce the toggling effect that may happen with the single use screwdriver.
The corresponding devices are the following:
- A ratchet screwdriver, with a 1/4″ connection bit, and a rotating handle to precisely maintain the trajectory during tightening, dismountable for cleaning. Screwdriver that can be connected to a 1/4″ ratchet handle.
NOTE: to ensure the best performance it is recommended to lubricate the connection between the ratchet screwdriver and the ratchet handle using approved instrument lubricants (e.g. Hinge FreeTM by Steris). Follow the instrument lubricant instructions for use. The area to be lubricated is highlighted below by the orange square.
- 2 Converter types, in order to allow the use of the screwdriver with other types of handles
WARNING: when using a k-wire the minimum length should be of 600 mm.
WARNING: When placing iliac screws, the hole must be tapped to a minimum of 2mm less than the screw size. For example, when placing the 8.0mm iliac screw with the Ratchet Screwdriver, the 7.0mm XL tap shall be used prior to screw insertion.
WARNING: The ratcheting screwdriver shall not be used to place, remove, or adjust any set screws. This could lead to excessive forces on the tip of the screwdriver.
PROCESSING (CLEANING, DISINFECTION, AND STERILIZATION)
FUNDAMENTAL POINTS
All instruments labelled as non-sterile are to be cleaned, disinfected, and
sterilized prior to each application; this is required as well for the first
use after delivery of the unsterile instruments (cleaning and disinfection
after removal of the protective packaging, sterilization after packaging). An
effective cleaning and disinfection is an indispensable requirement for an
effective sterilization of the instruments.
The sterility of the instruments falls under your responsibility. Please
ensure that only product specifically validated procedures will be used for
cleaning, disinfection, and sterilization, that the used devices (WD,
sterilizer) will be maintained and checked regularly, as well as that the
validated parameters will be applied for each cycle.
Additionally, please pay attention to the legal provisions valid for your
Country as well as to the hygienic instructions of the hospital. This applies
particularly to the different guidelines regarding the inactivation of prions
(not relevant for USA), which can require the application of cleaning
detergents with proven prion efficiency as well as a sterilization with more
intensive parameters.
Caution: Non-sterile instruments are provided in a protective packaging designed for maintaining the integrity and cleanliness of the product. However, in no case the product shall be sterilized within this packaging but needs to be removed from the package and be treated as follows.
CLEANING AND DISINFECTION
Basics
If possible, an automated procedure (WD (Washer-Disinfector)) should be used
for cleaning and disinfection of the instruments. A manual procedure – even in
case of application of an ultrasonic bath – should only be used if an
automated procedure is not available; in this case, the significantly lower
efficiency and reproducibility of a manual procedure has to be considered1.
The pre-treatment step is to be performed in both cases.
Please ensure already during use that you collect contaminated instruments
separately and do not place them back in the instrument tray to avoid greater
contamination of the loaded instrument tray.
1 In case of application of a manual cleaning and disinfection procedure a
product and procedure specific development and validation of the specific
manual procedure under sole responsibility of the user is required.
Pre-treatment
Please remove coarse impurities of the instruments directly after application
(within a maximum of 2 h).
Procedure:
- Rinse the instruments at least 1 min under running water (temperature < 35 °C/95 °F).
- Soak the instruments for the given soaking time in the pre-cleaning solution2, e.g. 0.5-2% neodisher® Mediclean forte for 10-30 min (with activated ultrasound) so that the instruments are completely covered. Pay attention that there is no contact between the instruments.
- Then, remove the instruments of the pre-cleaning solution and post-rinse them at least three times intensively (at least 1 min) with water (temperature <35°C/95 °F).
Ratcheting devices are cannulated, make sure the hole is cleaned and no impurities remain before proceeding with the automated cleaning. To obtain a clean cannula use a K-Wire or a soft brush to wipe the hole and then proceed with a water jet to flush the hole.
Pay attention to following points during selection of the cleaning detergent2:
- fundamental suitability for the cleaning of instruments made of metallic or plastic material
- suitability of the cleaning detergent for ultrasonic cleaning (no foam development)
- compatibility of the cleaning detergent with the instruments (see chapter „material resistance„)
Pay attention to the instructions of the detergent manufacturer regarding concentration, temperature and soaking time as well as post-rinsing. Please use only freshly prepared solutions as well as only sterile or low contaminated water (max. 10 germs/ml) as well as low endotoxin contaminated water (max. 0.25 endotoxin units/ml), for example purified/highly purified water, and a soft, clean, and lint-free cloth and/or filtered air for drying, respectively.
2 In case of application of a cleaning and disinfection detergent for this (e.g. in consequence of personnel´s safety) please consider, that this should be aldehyde-free (otherwise fixation of blood impurities), possess a fundamentally approved efficiency (for example VAH/DGHM or FDA/EPA approval/clearance/registration or CE marking), be suitable for the disinfection of instruments made of metallic or plastic material, and be compatible with the instruments (see chapter „material resistance„). Please consider, that a disinfectant used in the pre-treatment step serves only the personnel`s safety, but cannot replace the disinfection step later to be performed after cleaning.
Automated cleaning/disinfection (WD (Washer-Disinfector))
Pay attention to following points during selection of the WD:
-
WD according to EN ISO/ANSI AAMI ST15883 and with fundamentally approved efficiency (for example CE marking according to EN ISO 15883 or DGHM or FDA approval/clearance/registration)
-
if possible selection of an approved program for thermal disinfection (A0 value ≥ 3000 or – in case of older devices – at least 5 min at 90 °C/194 °F; in case of chemical disinfection danger of remnants of the disinfectant on the instruments)
-
fundamental suitability of the program for instruments
-
program with a sufficient number of rinsing steps (at least three degrading steps after cleaning (respectively neutralization, if applied) or conductance based rinsing control recommended in order to prevent effectively remnants of the detergents)
-
post-rinsing only with sterile or low contaminated water (max. 10 germs/ml, max. 0.25 endotoxin units/ml), for example purified/highly purified water
-
only use of filtered air (oil-free, low contamination with microorganisms and particles) for drying
-
regularly maintenance and check/calibration of the WD
Pay attention to following points during selection of the cleaning detergent: -
fundamental suitability for the cleaning of instruments made of metallic or plastic material
-
additional application – in case of non-application of a thermal disinfection – of a suitable disinfectant with approved efficiency (for example VAH/DGHM or FDA/EPA approval/clearance/registration or CE marking) compatible to the used cleaning detergent
-
compatibility of the used detergents with the instruments (see chapter „material resistance„)
Pay attention to the instructions of the detergent manufacturers regarding concentration, temperature and soaking time as well as post-rinsing.
Procedure: 1. Transfer the instruments in the WD (pay attention, that the instruments are located with the big opening downwards and that instruments have no contact).
2. Start the program, e.g.: -
pre-rinse 1 min with cold water <40°C
-
wash at 55°C with 0.5% neodisher® Mediclean forte for 10 min
-
rinse for 1 min with cold water <40°C
-
rinse for 2 min with deionized water <40°C
-
thermal disinfection for 5 min at >90°C with deionized water
-
drying for 30 min at 100°C
Remove the instruments of the WD after end of the program.
Check and pack the instruments immediately after the removal (see chapters
„check„, „maintenance„, and “packaging„, if necessary after additional post-
drying at a clean place).
The fundamental suitability of the instruments for an effective automated
cleaning and disinfection was demonstrated by an independent, governmentally
accredited and recognized (§ 15 (5) MPG) test laboratory by application of an
ultrasonic bath of the SONOREX series with 35 kHz (BANDELIN electronic,
Berlin) for pre-cleaning, the WD PG 8535, Miele & Cie. GmbH & Co., Gütersloh
(thermal disinfection) and the pre-cleaning and cleaning detergent neodisher®
Mediclean forte (Dr. Weigert GmbH & Co. KG, Hamburg) considering to the
specified procedure.
Check
Check all instruments after cleaning or cleaning/disinfection, respectively,
on corrosion, damaged surfaces, still readable marking. and impurities. Do not
further use damaged instruments (for limitation of the numbers of re-use
cycles see chapter „reusability„). Still dirty instruments are to be cleaned
and disinfected again.
Maintenance
Use of instrument lubricant is allowed for the junction between the rachet
screwdriver and the handle as shown in Section A.
Packaging
Please insert the cleaned and disinfected instruments in a standard
sterilization tray and pack them in sterilization containers, which fulfill
the following requirements (material/process):
- EN ISO/ANSI AAMI ISO 11607 (for USA: FDA clearance)
- suitable for steam sterilization (temperature resistance up to at least 142 °C (288 °F), sufficient steam permeability)
- sufficient protection of the instruments as well as of the sterilization packaging to mechanical damage
- regular maintenance according to the instructions of the manufacturer (sterilization container)
A maximum weight of 8 kg per content of the sterilization tray must not be exceeded.
Sterilization
Please use for sterilization only the listed sterilization procedures; other
sterilization procedures must not be applied.
Steam sterilization
- fractionated vacuum/dynamic air removal procedure3,4 (with sufficient product drying5)
- steam sterilizer according to EN 13060/EN 285 or ANSI AAMI ST79 (for USA: FDA clearance)
- validated according to EN ISO 17665 (valid IQ/OQ (commissioning) and product specific performance qualification (PQ))
- maximum sterilization temperature 137°C (278,6 °F; plus tolerance according to EN ISO 17665)
- sterilization time (exposure time at the sterilization temperature):
Area| fractionated vacuum/dynamic air removal| gravity
displacement
---|---|---
USA| 4 min at 132 °C (270 °F), drying time at least 20 min5| not recommended
Germany| 5 min6 at 134 °C (273 °F), drying time at least 20 min5| not
recommended
other countries| at least 4 min6 at 132 °C (270 °F) / 134 °C (273 °F), drying
time at least 20 min5| not recommended
at least three vacuum steps
The less effective gravity displacement procedure must not be used in case of availability of the fractionated vacuum procedure, requires significantly longer sterilization times as well as a sterilizer, procedure, parameter, and product specific process development and validation under sole responsibility of the user.
The effectively required drying time depends directly on parameters in sole responsibility of the user (load configuration and density, sterilizer conditions, …) and by this is to be determined by the user. Nevertheless, drying times less than 20 min must not be applied.
respectively 18 min (inactivation of prions, not relevant for USA)
The fundamental suitability of the instruments for an effective steam
sterilization was demonstrated by an independent, governmentally accredited
and recognized (§ 15 (5) MPG) test laboratory by application of the steam
sterilizer Tuttnauer EHS 3870 and the fractionated vacuum/dynamic air removal
procedure. For this, typical conditions in clinic as well as the specified
procedure were considered.
The flash/immediate use sterilization procedure must not be used.
Do not use dry heat sterilization, radiation sterilization, formaldehyde and
ethylene oxide sterilization, as well as plasma sterilization.
Storage
Please store the instruments after sterilization in the sterilization
packaging at a dry and dust-free place.
NOTE: upon customer requests Neo Medical can provide a transport tray where to keep the ratchet screwdriver components. Do not use the tray for sterilization of ratcheting devices.
Material resistance
Please take care that the listed substances are not ingredients of the
cleaning or disinfection detergent:
organic, mineral, and oxidizing acids (minimum admitted pH-value 5.5)
- strong lyes (maximum admitted pH-value 11, neutral/enzymatic, weak alkaline, or alkaline cleaner recommended)
- organic solvents (for example: acetone, ether, alcohol, benzine)
- oxidizing agents (for example: peroxide)
- halogens (chlorine, iodine, bromine)
- aromatic, halogenated hydrocarbons
Please consider during selection of the detergents in addition, that corrosion
inhibitors, neutralizing agents, and/or rinse aids may cause potential
critical remnants on the instruments.
Acid neutralizing agents or rinse aids must not be applied.
Please do not clean any instruments by use of metal brushes or steel wool.
Please do not expose any instruments to temperatures higher than 142 °C (288
°F)!
Reusability
Repeated processing cycles that include ultrasonic, mechanical washing and
sterilization have minimal effects on Neo Medical reusable surgical
instruments.
End of life of a reusable surgical instrument is normally determined by wear
and damage due to use. Evidence of damage and wear on a device may include but
is not limited to corrosion (i.e. rust, pitting), discoloration, excessive
scratches, deformation/twist of the screwdriver tip, flaking, wear and cracks.
Improperly functioning devices, devices with unrecognizable markings, missing
or removed (buffed off) part numbers, damaged and excessively worn devices
should not be used and must be absolutely replaced by a new one. The user is
responsible for each further use as well as for the use of damaged and dirty
instruments (no liability in case of disregard).
NOTA BENE: Ratchet handles can be reused up to 250 times, provided they are undamaged and uncontaminated. Products marked with a UDI code (machine- readable) can be reprocessed a maximum of 200 times. Any further use or use of damaged and/or contaminated instruments beyond this is the responsibility of the user. Any liability is excluded in the event of non-compliance.
ADDITIONAL INFORMATION
It remains the responsibility of the processor to ensure that the processing
is actually performed, using equipment, materials and personnel in the Central
Sterile Supply Department (CSSD), and achieves the desired result. This
requires verification/validation and routine monitoring of the process.
Likewise, any deviation by the processor from the recommendations provided
should be properly evaluated for effectiveness and potential adverse
consequences.
All users shall be qualified personnel with documented expertise, competency
