The needle guide systems include both fixed and adjustable needle guides. In one embodiment, the needle guide includes a needle guide body that is rotatably mounted to a probe of a sonography device. A plurality of needle channels is disposed on a surface of the needle guide body. Each needle channel can be selectively rotated into position to guide a needle into a body of a patient at a predetermined needle insertion angle. If another needle insertion angle is desired, the needle guide is rotated to place a new needle channel defining the desired needle insertion angle into position. In another embodiment, a needle guide is disclosed and includes an extended guide feature, such as a guide cone, to assist in inserting a needle into the needle channel. | 04-23-2015 |
20150133789 | PUNCTURE APPARATUS - A puncture apparatus is disclosed, which can include an elongated insertion portion configured to be inserted into a living body lumen, a puncture needle configured to puncture a living body tissue near the insertion portion from a part different from the living body lumen, with the insertion portion inserted in the living body lumen, a puncture needle guide portion, which movably supports the puncture needle and which determines a puncture path for a needle tip of the puncture needle when the puncture needle punctures the living body tissue, an ultrasonic transmission-reception section in the insertion portion or the puncture needle guide portion, for transmission and reception of an ultrasonic wave, and an image data production section for producing image data for displaying on a display section an image including the living body lumen and a predicted path of the puncture path, based on information acquired by the ultrasonic transmission-reception section. | 05-14-2015 |
20150320439 | ULTRASONICALLY GUIDED BIOPSIES IN THREE DIMENSIONS - An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane. | 11-12-2015 |
20150351717 | ULTRASOUND DIAGNOSTIC APPARATUS, METHOD OF TRANSMITTING AND RECEIVING ULTRASONIC WAVE, AND PROGRAM FOR TRANSMITTING AND RECEIVING ULTRASONIC WAVE - An ultrasound diagnostic apparatus includes plural ultrasound transducers which perform transmission and reception of ultrasonic waves toward a target site of a subject containing a puncture needle. A method of transmitting and receiving an ultrasonic wave uses the ultrasound transducers. The apparatus and the method form an ultrasonic beam to be transmitted from a transmit aperture set on the ultrasound transducers, acquire information relating to a specular-reflective component of the ultrasonic beam in the puncture needle, set a first receive aperture different from the transmit aperture set on the ultrasound transducers on the basis of the information relating to the specular-reflective component of the ultrasonic beam, and process an ultrasonic echo signal received by the ultrasound transducers using the first receive aperture. | 12-10-2015 |
20150366546 | SYSTEM AND METHOD FOR REAL-TIME ULTRASOUND GUIDED PROSTATE NEEDLE BIOPSIES USING A COMPLIANT ROBOTIC ARM - One or more of the present embodiments include systems and methods for utilizing an MRI image and real-time an ultrasound images to guide and/or restrict the movement of an ultrasound probe in position for collecting a biopsy core. A real-time ultrasound image is acquired and fused with pre-operative imaging modalities, such as an MRI image, to provide a three-dimensional model of the prostate. A multi-link robotic arm is provided with an end-effector and an ultrasound probe mounted thereto. Sensor information is used to track the ultrasound probe position with respect to the 3D model. The robotic arm allows for the implementation of a virtual remote center of motion (VRCM) about the transrectal probe tip, an adjustable compliant mode for the physician triggered movement of probe, a restrictive trajectory of joints of the robotic arm and active locking for stationary imaging of the prostate. | 12-24-2015 |
20160000399 | METHOD AND APPARATUS FOR ULTRASOUND NEEDLE GUIDANCE - A method and apparatus of ultrasound guidance for interventional procedures involving a needle includes acquiring ultrasound data from a region of interest, positioning the needle with respect to the region of interest, displaying an image based on the ultrasound data, calculating a risk of bending for the needle, and presenting the risk of bending for the needle. | 01-07-2016 |
20160051224 | NEEDLE GUIDE FOR ULTRASOUND TRANSDUCER - A needle guidance apparatus is an accessory that is configured to be coupled to an ultrasound transducer probe and is configured to align and guide the placement of a needle to a target location beneath the skin of a patient. | 02-25-2016 |
20160106381 | ULTRASOUND PROBE WITH TACTILE INDICATOR - A method and apparatus actuate a tactile indicator on a hand-contacted surface of the handheld ultrasound probe based upon a parameter of the handheld ultrasound probe. | 04-21-2016 |
20160120572 | Static pointing device - The present invention presents a static pointing device and methods to guide insertion of an invasive tubular device to a tissue object of a living body. The static pointing device is coupled with an ultrasound positioning apparatus, located in front of an ultrasound transducer and produces a linear shadow line in a visualized ultrasonographic field. An ultrasonographic view of a tissue object can be marked by the linear shadow line crossing said tissue object. An invasive tubular device held by the ultrasound positioning apparatus can be directed to the tissue object by calculated angulation of said invasive tubular device to have a longitudinal axis of said invasive tubular device cross the linear shadow line in the tissue object. | 05-05-2016 |
20160128719 | NEEDLE GUIDE DEVICES FOR MOUNTING ON IMAGING TRANSDUCERS OR ADAPTORS ON IMAGING TRANSDUCER, IMAGING TRANSDUCERS FOR MOUNTING NEEDLE GUIDE DEVICES AND ADAPTORS FOR IMAGING TRANSDUCERS FOR MOUNTING NEEDLE GUIDE DEVICES THEREON - A needle guide device for releasable mounting on an imaging transducer or on an adaptor bracket on an imaging transducer is disclosed. The needle guide device includes a universal lockable mounting member which is configured for slidable releasable engagement with a coupling member on a specially constructed imaging transducer or on a conventional imaging transducer onto which a specially constructed adaptor is mounted. The needle guide device makes use of a slidable mounting member to cooperate with the coupling member. The needle guide device is adjustable to establish various selectable angular trajectories for a needle and has a low profile form factor to result in the creation of a minimal blind zone when mounted on the transducer and even if establishing a large angle for shallow needle penetration. | 05-12-2016 |
