• Device Name: SODEM HIGH SPEED SYSTEM (ELECTRIC) (NEURO/SPINE SURGERY)
• Applicant: Sodemsystems
• Product Code: HBC · Neurology
• Decision Date: Oct 22, 2001
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 882.4360
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Sodem High Speed motor allows the fixation of spindles and craniotomes, which operate with drills, burs and cutters for drilling, cutting and sculpting the cranial and spinal bones. The Sodem High Speed System (Electric) includes a skull perforator motor, which powers a cranial perforation attachment and allows skull perforation. The System does not include the cranial perforation attachment. The safety of the skull perforation depends exclusively on the safety of the cranial perforation attachment, which is neither manufactured nor sold by Sodem, but is available on the market from other manufacturers. Both motors, attachments and cutting tools are for use in neurosurgery, as well craniotomy as spinal surgery.

Device Story

Sodem High Speed System (Electric) is a powered surgical drill system for neurosurgery. System components: console, foot pedal, two motors (high-speed motor and skull perforator motor), wires, attachments (spindles, craniotomes), and cutting tools (drills, burs, cutters). Console allows connection of motors and selection of maximum operating speed; foot pedal controls speed during operation. Used in OR by surgeons for bone drilling, cutting, and sculpting. High-speed motor (0-80,000 rpm) powers spindles/craniotomes; skull perforator motor (fixed 800 rpm) powers cranial perforation attachments. System provides mechanical power to surgical tools to facilitate bone removal, aiding in craniotomy and spinal access. Device is non-sterile; requires steam sterilization and decontamination by user facility.

Clinical Evidence

Bench testing only. No clinical data provided. Equivalence established through comparison of technical specifications, intended use, and design characteristics against predicate devices.

Technological Characteristics

System includes electric console, foot pedal, and motors. Patient-contact materials: surgical stainless steel. Speed control: console-adjustable (0-80,000 rpm for high-speed; fixed 800 rpm for perforator). Sterilization: steam. Compliance: IEC 60601, UL 2601. Connectivity: wired connections between console, motors, and pedal.

Indications for Use

Indicated for patients undergoing neurosurgical procedures, specifically craniotomy and spinal surgery, requiring drilling, cutting, or sculpting of cranial and spinal bones.

Regulatory Classification

Identification

An electric cranial drill motor is an electrically operated power source used with removable rotating surgical cutting tools or drill bits on a patient's skull.

# 3. PREDICATE DEVICES

The Sodem High Speed System (Electric) claims equivalence to the following systems:

- Stryker: Total Performance System (TPS) (K943541)
- E9000/Advantage (K990524 / K002523) - Linvatec:

{1}------------------------------------------------

## 4. DEVICE DESCRIPTION

The Sodem High Speed System (Electric) is a complete system including:

- two motors (a Skull Perforator motor and a High Speed motor), -
- a foot pedal, -
- a console allowing to connect the motors and to select their max. operating speed, -
- dedicated wires to connect the motors, the foot pedal and the console -
- attachments/spindles and craniotomes -
- drills, burs and cutters -

The motors are to be attached to the Sodem High Speed console and are operated with a foot pedal.

The Sodem High Speed System (Electric) is an electrical system developed in conformity with the norms IEC 60601 and UL 2601.

The Sodem High Speed System (Electric) is very similar in terms of use and technological characteristics to products currently on the market (TPS from Stryker and E9000 / Advantage from Linvatec).

Also, the Sodem High Speed System (Electric) is equivalent in terms of use with the Sodem High Speed System (Pneumatic) already submitted (K954717). The skull perforator motor has the same use than the Sodem Perforator Drive also already submitted (K993851).

# 5. INTENDED USE

The Sodem High Speed motor allows the fixation of spindles and craniotomes, which operate with drills, burs and cutters for drilling, cutting and sculpting the cranial and spinal bones.

The Sodem High Speed System (Electric) includes a skull perforator motor, which powers a cranial perforation attachment and allows skull perforation. The System does not include the cranial perforation attachment. The safety of the skull perforation depends exclusively on the safety of the cranial perforation attachment, which is neither manufactured nor sold by Sodem, but is available on the market from other manufacturers.

Both motors, attachments and cutting tools are for use in neurosurgery, as well craniotomy as spinal surgery.

{2}------------------------------------------------

# 6. BASIS FOR CLAIM OF SUBSTANTIAL EQUIVALENCE

The Sodem High Speed System (Electric) claims substantial equivalence to other currently marketed high-speed electric power systems. This claim is based on equivalence in:

### Intended use

The Sodem High Speed System (Electric) and predicate electric instruments share the same clinical applications and intended used (neurosurgery [spine and craniotomy]).

#### Materials

Patient contact materials for all systems consist of surgical stainless steel.

#### Sterility Status

All systems are supplied non-sterile except burs and drills (special 510k Nº K994175 for sterile drills and burs), requiring reprocessing between surgical applications. Sterilization of all systems is accomplished using steam. All systems require decontamination after use, and resterilization by the user facility.

#### System Description

#### Console ।

All cited systems are operated using an electrical power console. Console allows to select motors and to choose operating speed. All console provide one or more connection for several hand pieces/motors (ex E9000 of Linvatec one connection for 14 hand pieces, TPS of Stryker 3 connection for approximately 10 hand pieces). Difference between Sodem console and other currently marketed consoles is that Sodem console has two specific connection (one for High Speed Motor, and one for Skull Perforator Motor, an inversion is not possible).

#### Accessories

The Sodem High Speed System (Electric) and predicate systems consist of various attachments (burs, spindles). All offer a wide variety of accessories including but not limited to chuck, adapters, spindles and burs. The technical characteristics of the various adapters are identical or similar. That is, adapters allow the use of hand pieces with various power system accessories.

All hand pieces are designed with a terminal angle (nose piece). The Sodem and Stryker systems have an angled nose. The Linvatec E9000 / Advantage systems have an integral angling capability from straight to 20 degrees with a twist of the collet. All systems feature to ability to change burs and spindles without the need for a wrench.

{3}------------------------------------------------

#### Electrical power

All cited systems are operated using an electrical power source controlled by a foot pedal. For all systems, users can choose maximum operating speed on the console and with the foot pedal increase or reduce speed until maximum speed selected.

The nominal power output of the Sodem High Speed System is identical or substantially equivalent to the other commercially available electrical motors (Linvatec, Stryker). The maximum drill speed of the Sodem High Speed System (Electric) is adjustable with the console from 0-80'000 rpm, the drill speed of the E9000 / Advantage system of Linvatec is adjustable with the console from 0-80'000 rpm, the drill speed of the TPS of Stryker is adjustable with the console from 0-75'000 rpm. The skull perforator motors of Sodem and Linvatec have maximum and fixed speed of 800 rpm.

Based on the above comparison, SodemSystems believes that the Sodem High Speed System (Electric) is substantially equivalent to the systems cited, that any differences between the Sodem High Speed System (Electric) and these other currently available powered systems are minor and raise no new issues of safety and effectiveness.
