Abstract
A lithotriptor device embodiment is provided including a lithotriptor that has a proximal handle, an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft, and a wire basket distally attached to a drive wire. The drive wire extends through the lumen of the elongate shaft and is operatively connected to the handle. The device includes a drill mechanism assembly with a drill bit disposed near the distal end of the elongate shaft.
Claims20
A lithotriptor device comprising:
- a proximal handle;
- an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft;
- a wire basket distally attached to a drive wire, the drive wire extending through the lumen of the elongate shaft and operatively connected to the handle;
- and
- a drill mechanism assembly comprising a drill bit and disposed near the distal end of the elongate shaft.
A method for crushing an object, said method comprising the steps of:
- providing a medical lithotriptor device comprising:
- a proximal handle;
- an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft;
- a basket distally attached to a drive wire, the drive wire extending through the lumen of the elongate shaft and operatively connected to the handle;
- and
- a drill mechanism assembly comprising a drill bit and disposed near the distal end of the elongate shaft.
- engaging the basket around an object;
- and
- actuating the handle such that the drive wire is drawn proximally into the elongate shaft and the basket is drawn tightly around the object.
A lithotriptor device comprising:
- a proximal handle;
- an elongate shaft extending distally from the handle with a lumen extending through a major length of the elongate shaft;
