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.
Claims20
A medical device configured for guiding a needle, said device comprising:
- a base;
- a neck extending from said base;
- and
- an elongate shaft having a distal end couplable with said neck, a proximal end, and an elongated extent therebetween;
- wherein:
- a lumen extends through said elongate shaft, said neck, and said base;
- and
- said neck is flexible and configured to allow manipulation thereof by said elongate shaft when coupled with said neck to manipulate said neck to adjust and to align the lumen with a target within a patient's body without moving said base.
A system for gaining access into a patient's body, said system comprising:
- a base;
- a neck extending from an outer surface of said base;
- an elongate shaft having a distal end couplable with said neck, a proximal end, and an elongated extent therebetween;
- and
- an access needle;
- wherein:
- a lumen, sized to receive an outer circumference of said access needle, extends through said elongate shaft, said neck, and said base;
- said neck is flexible and configured to allow manipulation thereof by movement of said elongate shaft when coupled with said neck to manipulate said neck to adjust and to align the lumen and said access needle with a target within the patient's body without moving said base.
A method of accessing a target within a patient's body, said method comprising:
- grasping a handle formed on a proximal end of an elongate shaft, a distal end of the elongate shaft being engaged with a flexible neck extending from an outer surface of a base;
- extending a needle through a lumen extending through the distal end of the elongate shaft, the flexible neck, and the base;
- manipulating the elongate shaft to flex the flexible neck to adjust and to align the lumen and to adjust and to align the position of the needle with respect to the target within the patient without moving the base;
- and advancing the needle into the patient to the target.
