摘要:
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.
