Intended Use

The Fluorotactic Guidance System Mk. I will be used to assist in the accurate placement of a guiding device for surgery in which a linear trajectory insertion or placement is required. This system will use coordinated-fluoroscopy to allow intra-operative planning of the precise insertion point and angle of a device such as a screw, nail, or needle. The surgeon will place a registration artifact over the desired surgical area and capture two fluoroscopic images, which will then be displayed on two computer screens. The surgeon will manipulate a virtual guidewire on the screens, until the desired angle and placement is achieved. The system will then output 3D coordinates to the robot arm which will move the drill guide to a precise position.

Device Story

System assists surgeons in precise placement of surgical instruments (screws, nails, needles) requiring linear trajectory. Inputs: two orthogonal fluoroscopic images captured via C-arm; registration artifact with eight embedded steel balls placed over surgical site. Processing: PC with image acquisition card displays images; surgeon manipulates virtual guidewire on screen to plan trajectory; software calculates 3D coordinates based on fiducial ball locations. Output: robot arm moves drill guide to calculated orientation. Used in OR; operated by surgeon. Benefits: enables accurate intra-operative planning and robotic positioning of drill guide, improving surgical precision.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

System components: robot arm, registration/drill guide artifact (with embedded steel balls), fluoroscopic image intensifier (C-arm), PC with image acquisition card and dual monitors. Sensing: X-ray based fiducial registration. Connectivity: PC-based image acquisition. Software: PC-based planning and coordinate calculation.

Indications for Use

Indicated for surgical procedures requiring linear trajectory insertion or placement of devices such as screws, nails, or needles. Intended for use by surgeons for intra-operative planning and guidance.

Regulatory Classification

Identification

An antinuclear antibody immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoimmune antibodies in serum, other body fluids, and tissues that react with cellular nuclear constituents (molecules present in the nucleus of a cell, such as ribonucleic acid, deoxyribonucleic acid, or nuclear proteins). The measurements aid in the diagnosis of systemic lupus erythematosus (a multisystem autoimmune disease in which antibodies attack the victim's own tissues), hepatitis (a liver disease), rheumatoid arthritis, Sjögren's syndrome (arthritis with inflammation of the eye, eyelid, and salivary glands), and systemic sclerosis (chronic hardening and shrinking of many body tissues).

Description:

The Fluorotactic Guidance System Mk. I is an integrated system that enables a surgeon to The Fluorotactic Guidance System Mik. I is all mice states, and other surgical instruments using two captured fluoroscopic images. An electromechanical arm is used to instruments using two captured indoroscopic mages. The capacity of the two approximately orthogonal images are captured with a standard flouroscope. The two images are displayed on computer monitors and used to perform accurate intra-operative planning. The plan consists of specifying the instrument entry point, and sagittal and transverse The plan consists of specifying the misulate the necessary coordinates for the robot arm, which will position the drill guide over the surgical area.

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

Summary of technological characteristics:

The Fluorotactic Guidance System Mk. I system will consist of four components:

- 1) Robot arm
- 2) Registration/drill guide artifact
- 3) Fluoroscopic image intensifier system (C-arm)
- 3) Pludical computer (PC) with a Data Translation image acquisition card and two monitors

The robot arm will hold a registration artifact which is transparent to X-rays over the patient in proximity to the desired surgical area. This artifact has eight steel balls embedded such that when the C-arm is used to capture images of the area, the balls will entibediced shadows on the image. Two images will be required, an Anterior/Posterior (A/P) view and a Sagittal view.

The PC will receive the image data from the C-Arm and display it on two monitors. The surgeon will indicate the desired positioning of the drill by manipulating a virtual suidewire on the screens. The software will then use the fiducial location information to calculate the coordinates for the positioning of the drill guide, and the robot arm will move to the new orientation.
