Abstract
A medical screwdriver for inserting a medical screw connected to a suture into a bone. The screwdriver includes a shaft adapted to hold a medical screw at its distal end, a motor adapted to rotate the shaft, and a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft.
Claims13
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a substantially straight shaft which holds a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft, and
- wherein the suture receiving channel comprises a through bore defined in the shaft.
In combination, a medical screw connected to a suture and a medical screwdriver for inserting the medical screw into a bone, comprising:
- a substantially straight shaft which holds the medical screw at its distal end;
- a motor adapted to rotate the shaft;
- and
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- and
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft,
- wherein the suture-receiving channel comprises a through bore in the shaft to define a hollow shaft, and
- wherein the hollow shaft is coupled to the motor through a gear pair.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- and
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft,
- wherein the suture-receiving channel comprises a through bore in the shaft to define a hollow shaft, and
- wherein the hollow shaft is coupled to the motor through a shaft housing which defines a bore therethrough.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- and
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft, and
- wherein the motor is held in a casing which defines a through channel, which channel leads from a first side of the casing close to a coupling to the shaft to an opposite side of the casing.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft, and
- a switch having a first position in which a suture located in the channel is held tightly and a second position in which the suture is free to move.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft,
- a stationary sheath which surrounds the shaft, and
- wherein the stationary sheath comprises a key which is adapted to fit in a respective notch in a casing of the motor.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a substantially straight shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft,
- a substantially straight, stationary sheath which surrounds the shaft, and
- wherein the channel is defined between the stationary sheath and the shaft.
A medical screwdriver for inserting a medical screw connected to a suture into a bone, comprising:
- a substantially straight shaft adapted to hold a medical screw at its distal end;
- a motor adapted to rotate the shaft;
- a suture-receiving channel leading from the distal end of the shaft to a point distanced from the distal end of the shaft by at least 50% of the length of the shaft,
- a substantially straight, stationary sheath which surrounds the shaft, and
- wherein the stationary sheath comprises a distal collapsible shield which is adapted to cover, in the absence of an axially applied force, at least a portion of a screw held by the shaft.
