Intended Use

The Tactile Guidance System v2.0 is intended to assist the surgeon in providing software defined spatial boundaries for orientation and reference information to anatomical structures during orthopedic procedures. The Tactile Guidance System v2.0 is indicated for use in surgical knee procedures, in which the use of stereotactic surgery may be appropriate, and where reference to rigid anatomical bony structures can be identified relative to a CT based model of the anatomy. These procedures include unicondylar knee replacement and/or patellofemoral knee replacement.

Device Story

Stereotaxic instrument for orthopedic surgery; assists surgeons with presurgical planning and intraoperative navigation. Inputs: patient CT data; optical tracking of surgical tools/arrays. Operation: system uses CT-based anatomical model to define spatial boundaries; robotic arm acts as intelligent tool guide, providing haptic/tactile feedback to constrain surgeon movement within software-defined limits. Output: visual navigation on LCD monitors; physical guidance via robotic arm. Used in OR by surgeons. Benefits: enables minimally invasive procedures by ensuring precise tool positioning relative to patient anatomy; prevents deviation from planned surgical path.

Clinical Evidence

No clinical data provided; substantial equivalence supported by bench testing and design validation.

Technological Characteristics

Stereotaxic instrument comprising robotic arm, optical detector, computer, LCD monitors, and surgical tools. Software runs on QNX and Linux operating systems. Connectivity includes encrypted data transfer via USB. Power provided by UPS and isolation transformer. System utilizes optical tracking for spatial registration.

Indications for Use

Indicated for surgical knee procedures, including unicondylar and patellofemoral knee replacement, where stereotactic surgery is appropriate and rigid anatomical bony structures can be identified relative to a CT-based model.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

Substantial Equivalence Claimed To: The Tactile Guidance System (TGS) v2.0 is substantially equivalent to the MAKO Surgical's Tactile Guidance System (K072806) and Voyager/Tactile Guidance System-CT (K052851) and Biomet's Acumen™ Surgical Navigation System (K031454 and K031337).

Description: The TGS v2.0 is a stereotaxic instrument that includes an optical detector, computer, dedicated instrumentation, operating software, tools and accessories, and a robotic arm. TGS v2.0 uses patient CT data to assist the physician with presurgical planning and interpretive navigation. The robotic arm serves as an "intelligent" tool holder or tool guide used by a surgeon for stereotactic guidance during minimally invasive orthopedic surgical procedures. The robotic arm, an electromechanical arm, is passively constrained by software-defined spatial boundaries implemented through the use of the robotic arm and is designed to support a surgeon's preparation of an anatomical site for an orthopedic implant with standard surgical tools such as drills and awls.

#### Summary of Technological Characteristics:

The TGS v2.0 consists of the following basic components:

- 1. Robotic Arm
- . User Panel
- Computer .
- CRISIS software application .
- QNX operating system .
- . Power components
- . Uninterruptible Power Supply (UPS)
- Cable panel .
- Positioning lever .
- Integrated cutting system .
- Isolation transformer
- 2. Guidance Module
- . High Resolution Color Liquid Crystal Display (LCD) Monitor
- � Computer
- . Software drivers for video grabber, standard components (keyboard, mouse, monitor, etc.)
- Knee software application .
- Linux operating system .
- Keyboard and Mouse
- 3. Camera Stand
- Second High Resolution LCD screen that shows an identical image to the primary touch . screen
