TOOLS FOR IMPLANTATION AND EXTRACTION OF POSTERIORLY PLACED LUMBAR ARTICIAL DISCS INCLUDING: A TOTALLY WIRELESS ELECTRONICALLY EMBEDDED ACTION-ENDED ENDOSCOPE UTILIZING DIFFERENTIAL DIRECTIONAL ILLUMINATION WITH DIGITALLY CONTROLLED MIRRORS AND/OR PRISMS, AND A DISC BALL INSERTER , A PLATE EXTRACTOR, AND RESCUE DISC PLATES
First Claim
1. A hand manipulated endoscopic medical device, comprising:
- a body;
a proximal end, which is hand manipulated;
a distal end which includes a manipulator;
a light emitting device which is centrally disposed at the distal end; and
an imaging device which is centrally disposed at the distal end for imaging at least a portion of the region illuminated by the light emitting device.

Abstract
A hand manipulated endoscopic medical device is disclosed. The medical device includes a body having a proximal end, which is hand manipulated, and a distal end which includes a manipulator. A light emitting device is centrally disposed at the distal end. An imaging device is centrally disposed at the distal end for imaging at least a portion of the region illuminated by the light emitting device. Also disclosed is a tool for extracting an artificial lumbar disc from between a pair of vertebral plates. The extraction tool includes a handle, a member for transmitting force, and a sharpened end, specially configured to be placed between the artificial disc and the vertebral plate. Further disclosed is a tool for implanting or explanting a ball to or from an artificial lumbar disc. The implanter/explanter includes a pinion shaft and a pinion shaft enclosure. A tightening knob is disposed at the proximal end of the shaft enclosure and coupled to the pinion shaft. A pinion is disposed at the distal end of the pinion shaft. A grappling device is disposed at the pinion, and it includes a pair of semi-circular rings. When the pinion is rotated, the semi-circular rings move relative to one another and are capable of grasping or releasing the ball.

40. A tool for extracting an artificial lumbar disc from between a pair of vertebral plates, comprising:
-
a handle;
a member, connected to the handle, for transmitting force;
a sharpened end, specially configured to be placed between the artificial disc and the vertebral plate, and responsive to the force exerted by the member.

41. A tool for implanting or explanting a ball to or from an artificial lumbar disc, comprising:
-
a pinion shaft;
a pinion shaft enclosure, for enclosing the pinion shaft, and including a pinion shaft key;
a tightening knob disposed at the proximal end of the shaft enclosure and coupled to the pinion shaft;
a pinion disposed at the distal end of the pinion shaft; and
a grappling device, disposed at the pinion, including a pair of semi-circular rings;
wherein the rotation of the pinion causes the semi-circular rings to move relative to one another in order to grasp or release the ball. - View Dependent Claims (42)
