    摘要: A real-time tracking of surgical tools relative to a pre-operative surgical plan and intra-operative images involves an image-based registration and tool tracking registration. The image-based registration implements an integration of a plurality of images of an anatomical region of a body including a pre-operative scan image (31) (e.g., a 3D CT/MRI image), an intra-operative fluoroscopic image (42) (e.g., an 2D X-ray image) and an intra- operative endoscopic image (23) (e.g., an 2D arthroscopic image). The tool tracking registration implements a representation within the pre-operative scan image (31) and/or the intra-operative fluoroscopic image (42) of a tracking of one or more surgical tools within the intra-operative endoscopic image (23).

    摘要: An endoscopic method involves an advancement of an endoscope (20) as controlled by an endoscopic robot (31) to a target location within an anatomical region of a body, and a generation of a plurality of monocular endoscopic images (80) of the anatomical region as the endoscope (20) is advanced to the target location by the endoscopic robot (31). For avoiding or detecting a collision of the endoscope (20) with and object within monocular endoscopic images (80) (e.g., a ligament within monocular endoscopic images of a knee), the method further involves a generation of distance measurements of the endoscope (20) from the object as the endoscope (20) is advanced to the target location by the endoscopic robot (31), and a reconstruction of a three-dimensional image of a surface of the object within the monocular endoscopic images (80) as a function of the distance measurements (81).

    摘要: An endoscopic surgical method involves an advancement of an endoscope (20) to a target location within an anatomical region of a body and a generation of a plurality of endoscopic video frames (22) as the endoscope (20) is advanced to the target location with the endoscopic video frames (2) illustrating monocular endoscopic images of the anatomical region. For real-time estimation of a depth of an object within monocular endoscopic images (e.g., depth of a bronchial wall within an monocular endoscopic images of a bronchial tube), the method further involves (S41) a determination of an optical flow of one or more image points within a frame time series of the monocular endoscopic images of the anatomical region, and (S42) an estimation of a depth field indicative of a depth of the object within the monocular endoscopic images as a function of the optical flow of the image point(s).

    摘要: An interlocking nested cannula set (231) has a plurality of telescoping tubes cooperatively configured and dimensioned to reach a target location relative to an anatomical region. Each tube has a pre-set interlocking shape. A nesting of an inner tube (30) within an outer tube (40) includes a gap (50) between the tubes (30, 40), which interlock within the gap (50) to limit rotation of the tubes (30, 40) relative to the gap (50). The interlocking shapes of the tubes (30, 40) may be identical or different. Examples of the interlocking shapes of a polygonal interlocking shape, a non-circular closed curve interlocking shape, a polygonal-closed curve hybrid interlocking shape and a keyway interlocking shape.

In operation, the system (200) constructs a configuration space node structure representing a discretized configuration space including a plurality of states characterized by one or more parameters, and augments the configuration space node structure with discrete parameter values explicitly quantifying each node of the configuration space node structure and/or with heuristic values serving as a search guide through a free space region of the discretized configuration space.

    摘要: An optical detection tool employs a surgical end-effector (30) and an optical fiber (20). In operation, the surgical end-effector (30) is navigated within an anatomical region relative to an object foreign to the anatomical region and the optical fiber (20) generates an encoded optical signal indicative of a strain measurement profile of the optical fiber (20) as the surgical end-effector (30) is navigated within the anatomical region. The optical fiber (20) has a detection segment in a defined spatial relationship with the surgical end-effector (30). The strain measurement profile represents a normal profile in the absence of any measurable contact of the foreign object with the detection segment of the optical fiber (20). Conversely, the strain measurement profile represents an abnormal profile in response to a measurable contact of the foreign object with the detection segment of the optical fiber (20).

    摘要: A method for reconstructing a surface of a three-dimensional object (41) involves a projection of a laser spot pattern (12, 14) onto the surface of the three-dimensional object (41) by a laser (11), and a generation of a series of endoscopic images (24) as an endoscope (21) is translated and/or rotated relative to the three-dimensional object (41). Each endoscopic image (24) illustrates a different view (23) of a laser spot array (13, 15) within the laser spot pattern (12, 14) as projected onto the surface of the three-dimensional object (41) by the laser (11). The laser spot array (13, 15) may be identical to or a subset of the laser spot pattern (12, 14). The method further involves a reconstruction of the surface of the three-dimensional object (41) from a correspondence of the different views (23) of the laser spot array (13, 15) as illustrated in the endoscopic images (24).
