Intended Use

The Primado 2 is an AC-electrically powered total surgical system that is intended for cutting, drilling, sawing, and otherwise manipulating soft tissue, bone, bone cement, prosthesis, implant, and other bone related tissue in a variety of surgical procedures, including but not limited to Cranial (Craniofacial), ENT, Endoscopic / Arthroscopic, Neuro, Orthopedic, Spinal, and General surgical procedures.

Device Story

Primado2 is an AC-powered surgical system comprising a control unit, optional foot control, and various motor-driven handpieces (e.g., slim, high torque, bone saw, wire pin driver). System accepts burs, drills, saw blades, and rasps for surgical manipulation of bone and soft tissue. Control unit manages motor speed, rotation direction, and integrated irrigation functions; supports asynchronous operation of two motors. Foot control provides user-programmable interface for functions like ON/OFF, speed, reverse, and irrigation. Used in clinical settings (OR) by surgeons. Output is mechanical power for surgical cutting/drilling. System benefits patients by enabling precise tissue/bone manipulation during diverse surgical procedures.

Clinical Evidence

Bench testing only. Verification and validation testing performed to internal functional specifications, including software. Compliance with IEC 60601-1 (electrical safety) and IEC 60601-1-2 (EMC) confirmed. Biocompatibility and sterilization validations performed. No clinical data presented.

Technological Characteristics

AC-electrically powered surgical system. Components: control unit, foot control, motors, handpieces, and attachments. Software-driven control of speed, rotation, irrigation, and configuration. Connectivity: supports two simultaneous motor connections. Standards: IEC 60601-1, IEC 60601-1-2. Biocompatibility and sterilization standards applied.

Indications for Use

Indicated for cutting, drilling, sawing, and manipulating soft tissue, bone, bone cement, prostheses, and implants in cranial, ENT, endoscopic/arthroscopic, neuro, orthopedic, spinal, and general surgical procedures.

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.

### 510(k) SUMMARY (continued)

Device Description: (continued)

The control unit drives the motors during procedures and is used to control the functions related to that motor such as speed and rotational direction. Two motors can be connected to the control unit at one time for asynchronous use. The control unit also incorporates the irrigation pump and controls the irrigation functions.

The foot control is an optional additional user interface. The foot control is available as a single or multi control. The single foot control has one button that can be programmed. The multi foot control has three buttons that can be programmed. The features available for allocation to the buttons include Foot Control ON/OFF, A/B Control Switching, Speed Control, Reverse Rotation, Irrigation ON/OFF, Flush, and Disable.
