Embodiment Construction

[0020] image 3 The interventional system 40 shown in FIG. 2 employs a tracking workstation 50 and an interventional instrument 60 .

[0021] The tracking workstation 50 is structurally configured for combining intraoperative real-time imaging modalities (such as X-ray, endoscopic or ultrasound) with preoperative Arbitrary workstation for registration of imaging modalities such as computed tomography or magnetic resonance imaging. As will be appreciated by those skilled in the art, the purpose of image registration is to use preoperative and / or intraoperative images of the anatomical region as visual guides for the interventional instrument 60 to move from the point of entry into the anatomical region to the Intraoperative navigation of target locations within anatomical regions. To this end, the tracker workstation includes position sensor(s) incorporated into instrument 60, as described subsequently herein. Examples of tracking workstations 50 include, but are not limited ...

Abstract

An interventional instrument (60) employs a rod (61) and a rod tracker (62), the rod tracker (62) partially or completely surrounding the rod (61) and capable of The distance between the distal tip and the proximal sleeve moves along the rod (61) to the primary tracking position. The primary tracking position is derived from the distance from the entry point of the distal tip into the anatomical region to the target position of the distal tip within the anatomical region. The rod tracker (62) includes a primary position sensor (63) that can be used to track the rod tracking relative to the anatomical region at or offset from the primary tracking position device (62).

Description

technical field [0001] The present invention generally relates to tracking of navigation of interventional instruments during minimally invasive interventions and surgical procedures. The invention relates in particular to a rod tracker integrated on the rod of the interventional instrument for facilitating the tracking of the navigation of the interventional device. Background technique [0002] Electromagnetic ("EM") and optical tracking have proven to be useful tools for many minimally invasive interventional and surgical procedures. Specifically, linking intraoperative real-time imaging modalities (such as X-ray, endoscopy, and ultrasound) with preoperative imaging modalities (such as computed tomography and magnetic resonance imaging) via the aid of EM tracking or optical tracking, by This can use the pre-operative roadmap to aid in the guidance of real-time imaging. Furthermore, by attaching or embedding tracking EM sensor coils or tracking optical markers into the i...
