Surgical guidance devices, systems and methods

Abstract

A guidance device is disclosed. The device may comprise a tracking pad with a guiding opening and a plurality of sensors operable with at least one beacon on a needle to track the disposition of the needle at least when a distal end of the needle is inserted into the guiding opening. Related systems and methods are also disclosed.

Description

technical field [0001] Aspects of the disclosure relate generally to medical devices and procedures. In particular, some aspects relate to surgical guide devices, systems, and methods. Background technique [0002] The non-invasive surgical procedure advantageously allows physicians to treat interior regions of the body without having to create large physical openings in the body's exterior skin. Many non-invasive procedures are specialized to treat specific areas of the body, such as organs. Percutaneous nephroscopy (or "PCNL"), for example, is one such procedure in which an object such as a needle is inserted through the body and into the kidney to remove a kidney stone. Precise placement of the needle is required to avoid damage to the kidney. Accordingly, medical imaging techniques such as fluoroscopy can be used in PCNL procedures to both locate the kidney and track the position of the needle relative to the located kidney. [0003] Many imaging techniques are limit...

Problems solved by technology

These techniques can be used to localize organs and determine the distance between objects and organs; however, they are often not suitable for directing objects to organs

For example, the PCNL needle may be pushed out of the imaging plane by body tissue, requiring the physician to reposition the imaging plane relative to the needle and kidney (which is time consuming); or relying solely on tactile sensation for body guidance, which is imprecise and harmful to the body. potentially harmful

Also, because many of these imaging techniques generate 2D images of 3D bodies, they may distort or blur the geometric relationship between objects and bodies

In PCNL procedures, for example, these limitations can make it difficult for physicians to determine whether the needle is advancing toward the kidney at the desired angle of insertion
