Problems solved by technology

In addition, the skin surface may become deformed during the procedure, e.g. due to movement of body parts or opening of an incision at the surgical site
However, deformation of the skin surface may cause part of the tracker sheet attached to it to detach, which will impair surgical navigation.

Embodiment Construction

[0034] In the following description, exemplary embodiments of a tracker for surgical navigation and a method for operating the same will be explained with reference to the accompanying drawings. The same reference numerals will be used to denote the same or similar structural features.

[0035] Figure 1 shows a first embodiment of a tracker 10 in an undeformed configuration. Tracker 10 includes sheet 12 . The sheet 12 comprises a deformable material. The sheet body 12 may, for example, include at least one of polyimide (P1), liquid crystal polymer (LCP), and polyurethane (PU) such as thermoplastic PU (TPU). Additionally or alternatively, the panel 12 may comprise other materials that bring about the deformability of the panel 12, such as rubber or textile. The sheet 12 may comprise open-pored and / or closed-pored foam. The sheet 12 can be manufactured as a moulding.

[0036] The sheet 12 is elastically deformable, and is thus (at least partially) configured to return to it...

Abstract

A tracker (10) for surgical navigation and an operating method thereof are described. The tracker comprises a patch (12) being deformable in at least one direction and a tracker element selected froma light source (14) or a coil (15), the tracker element being supported by the patch. The tracker further comprises an electrical connection (16) electrically coupled to the tracker element and supported by the patch, the electrical connection having a meandering configuration along the direction in which the patch is deformable.

Description

technical field [0001] The present disclosure generally relates to trackers for surgical navigation. In particular, a tracker comprising a deformable sheet is proposed. Background technique [0002] Many procedures benefit from determining the position and orientation (ie, pose) of surgical objects, such as surgical instruments and the patient, in the operating room. A surgical navigation system may be employed to track the surgical instrument relative to the patient and to calculate the current pose of the surgical instrument relative to the patient's registered three-dimensional image data. [0003] In a typical application of a surgical navigation system, both a surgical instrument and a patient are associated with a tracker, where three-dimensional image data previously obtained by, for example, a computed tomography (CT) scan is initially registered with the pose of the patient tracker. Then, by continuously tracking the patient and surgical instruments, the surgical ...
