Guidance, tracking and guidance system for positioning surgical instruments within a patient's body

摘要

A guidance, tracking and guidance system (1) for positioning the surgical instrument (5) in the body of the patient (P) comprises the spatial position of the control unit (2), the display (3) and the viewer (3). And first detection means (4) for determining. The system (1) further comprises a sensor associated with the surgical instrument (5) and insertable into an internal part (Pi) of the patient (P) body. The probe includes at least one optical guide and detection means for detecting light beam scattering. At least one of the optical guides has a light scattering region generated within the optical guide. The detecting means detects the scattering of the light flux in order to specify the spatial arrangement of the probe when inserted into the patient (P). The control unit (2) displays on the viewer (3) an image of the internal state of at least one internal part (Pi) of the patient (P) 's body, an image of the probe based on the identified spatial arrangement, Is configured to project.
