Abstract
The present disclosure relates generally to the field of medical devices and establishing access to a target within the body, such as placing an access needle into a renal capsule into the human body. In particular, the present disclosure relates to devices and methods for performing a percutaneous nephrolithotomy (PCNL) procedure accurately and efficiently while minimizing exposure of the medical professional to harmful radiation.
Claims18
A medical device, comprising:
- an elongate shaft having a distal end and a proximal end and an elongated extent therebetween;
- a base;
- and
- a lumen extending through the base and the distal end of the elongate shaft transverse to the elongated extent of the shaft;
- wherein:
- the distal end of the shaft is attached to the base;
- and
- the shaft extends laterally away from the base and to the proximal end, and is rotatable, twistable, raisable, lowerable, and pivotable to adjust the orientation of the lumen.
5 more elements
A medical device, comprising:
- an elongate shaft having a distal end and a proximal end and an elongated extent therebetween;
- a base having a housing and a ball rotationally disposed within the housing;
- and
- a lumen extending through the elongate shaft and the ball transverse to the elongated extent of the elongate shaft;
- wherein:
- the distal end of the elongate shaft is attached to an outer surface of the ball;
- the elongate shaft extends laterally away from the ball at the distal end thereof to a handle at the proximal end thereof and is graspable to move the lumen within the ball with respect to the base;
- and
- the shaft extends laterally away from the base and is rotatable, twistable, raisable, lowerable, and pivotable to adjust the orientation of the lumen.
6 more elements
A medical device comprising:
- an elongate shaft having a distal end and a proximal end and an elongated extent therebetween;
- a base;
- a lumen extending through the base and the distal end of the elongate shaft transverse to the elongated extent of the shaft;
- and
- a release lever on the shaft movable between a first position in which the shaft is operable to adjust the orientation of the lumen, and a second position in which the orientation of the lumen is not adjustable;
- wherein:
- the distal end of the shaft contacts the base;
- and
- the shaft extends laterally away from the base and to the proximal end, and is rotatable, twistable, raisable, lowerable, and pivotable to adjust the orientation of the lumen.
