Intended Use

The Tactile Guidance System 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 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

Device Story

TGS is a stereotaxic instrument for orthopedic surgery; assists surgeons with presurgical planning and intraoperative navigation. Input: patient CT data. Operation: system uses optical detector and computer to track surgical tools relative to patient anatomy; robotic arm acts as an 'intelligent' tool holder/guide. Software defines spatial boundaries to constrain the robotic arm, ensuring precise preparation of anatomical sites for implants. Used in OR by surgeons; supports standard tools like drills and awls. Benefits: provides haptic/spatial guidance during minimally invasive procedures, improving accuracy of implant placement. Preoperative planning performed on a separate laptop; plans transferred via encrypted USB to TGS.

Clinical Evidence

No clinical data provided. Bench testing only.

Technological Characteristics

System components: optical detector, CPU, Linux-based OS, dual LCD touch screens, isolation transformer, foot control panel, and robotic arm. Connectivity: USB for plan transfer, optical tracking for tool positioning. Software: Voyager application for navigation and spatial boundary definition. Power: UPS. Sterilization: standard surgical tool compatibility.

Indications for Use

Indicated for surgical knee procedures, specifically unicondylar 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 TGS is substantially equivalent to the Voyager / Tactile Guidance System - CT (K052851), Uni-Knee Surgetics Navigation System (K062146), Acumen System (K031454, K031337), Vectorvision Uni-Knee (K041899), and Navitrack System-OS Unicondylar Knee Universal (K071714).

Description: The TGS is a stereotaxic instrument that includes an optical detector, computer, dedicated instrumentation, operating software, tools and accessories, and the TGS robotic arm. TGS uses patient CT data to assist the physician with presurgical planning and interpretive navigation. The TGS robotic arm, which is an add-on to the Navigation Module, serves as an "intelligent" tool holder or tool guide used by a surgeon for stereotactic guidance during minimally invasive orthopedic surgical procedures. The TGS robotic arm, an electromechanical arm, is passively constrained by softwaredefined spatial boundaries implemented through the use of the TGS 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, awls, and 3rd party drill systems.

Summary of Technological Characteristics: The TGS consists of the following basic components:

- High Resolution Color Liquid Crystal Display (LCD) Touch Screen Monitor ﮩ
- Second High Resolution LCD screen that shows an identical image to the primary touch screen.
- Uninterruptible Power Supply (UPS)
- Central Processing Unit (CPU) ব
- 5. Isolation Transformer
- ్. Keyboard and Mouse
- 7. Optical Detector
- Operating Room (OR) Cart 8.
- Foot control panel ഗ്
- 10. Tool and accessories optically tracked surgical tools and accessories
- 11. TGS robotic arm tool platform that is connected to the Voyager Navigation Platform to enable passive stereotactic guidance of any cleared standard surgical tool such as 30 party drill systems (e.g., Anspach's eMax (K011444)) to prepare anatomical sites for placement of orthopedic implants in a minimally invasive manner.
- 12. Voyager software application
- 13. Linux operating system
- 14. Software drivers for video grabber, standard components (keyboard, mouse, monitor, etc.)
- 15. Preoperative planning laptop that runs only the preoperative planning portion of the application. Dicom CDs of CT scans with patient data can be loaded and surgical plans can be created on this laptop and downloaded (in an encrypted format) to a USB memory stick to be transferred to the TGS.
