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.

Dependent claims

A hand manipulated endoscopic medical device, comprising:

a tool body having a proximal end and a distal end;
first and second hand-operated manipulators at the proximal end;
a pair of forceps at the distal end, the pair of forceps responsive to operation of the pair of hand-operated manipulators, wherein each of the pair of forceps is rotatable about an axis, and wherein an angle of attack of each of the pair of forceps is adjustable, and wherein each of the pair of forceps includes a jaw pivot gear;
a position selector engaging each of the pair of forceps and a pinion, wherein rotation of the pinion moves the position selector, which rotates at least one of the pair of forceps about the axis;
a light emitting device having a light generator disposed in the tool body at the proximal end of the tool body, the light emitting device configured to emit light, which is generated by the light generator, at the pair of forceps, the light emitting device disposed in the tool body;
and
an imaging device configured to capture images at the pair of forceps, the imaging device disposed in the tool body,
wherein the position selector comprises:
a first side having a plurality of first pinion contact spurs and a second side having a plurality of second pinion contact spurs, the first and second pinion contact spurs arranged to engage the pinion, wherein rotation of the pinion acts on the first and second pinion contact spurs to rotate the position selector;
and
a plurality of first contacts engaging the jaw pivot gear of a first one of the pair of forceps and a plurality of second contacts engaging the jaw pivot gear of a second one of the pair of forceps, wherein rotation of the position selector adjusts the angle of attack of each of the pair of forceps and locks the angle of attack in place.

A method of operating a hand manipulated endoscopic medical device that comprises a tool body having a proximal end and a distal end;

first and second hand-operated manipulators at the proximal end;
a pair of forceps at the distal end, the pair of forceps responsive to operation of the pair of hand-operated manipulators, wherein each of the pair of forceps is rotatable about an axis, and wherein an angle of attack of each of the pair of forceps is adjustable, and wherein each of the pair of forceps includes a jaw pivot gear;
a position selector engaging each of the pair of forceps and a pinion;
a light emitting device having a light generator disposed in the tool body at the proximal end of the tool body, the light emitting device configured to emit light, which is generated by the light generator, at the pair of forceps, the light emitting device disposed in the tool body;
and an imaging device configured to capture images at the pair of forceps, the imaging device disposed in the tool body;
wherein the position selector comprises a first side having a plurality of first pinion contact spurs and a second side having a plurality of second pinion contact spurs, the first and second pinion contact spurs arranged to engage the pinion, wherein rotation of the pinion acts on the first and second pinion contact spurs to rotate the position selector;
and the position selector further comprises a plurality of first contacts engaging the jaw pivot gear of a first one of the pair of forceps and a plurality of second contacts engaging the jaw pivot gear of a second one of the pair of forceps, wherein the method comprises:
inserting the hand manipulated endoscopic medical device into a patient at a surgical target site;
actuating the first and second hand-operated manipulators to operate the pair of forceps;
rotating the pinion to move the position selector to rotate at least one of the pair of forceps about the axis to adjust the angle of attack of the pair of forceps and lock the angle of attack in place;
and
capturing images of the surgical target site via the imaging device.
