A system for aiding surgery on a patient is described including a display device and a storage device that stores an image of at least a portion of the anatomy of the patient, including one or more surgical navigation markers positioned on the patient, for display on the display device. An analyser is adapted to receive positional data of a probe based on positioning of the probe relative to the one or more markers on the patient. Based on the positional data, the analyser outputs correctional data to adjust an alignment of the image on the display device to match locations of said one or more markers.

A system for ablating or monitoring a zone of the heart, includes a system to measure the heart electrical activity; a phased array for generating a beam of focussed ultrasound signals on a targeted zone of the heart; an imaging system determining an image of a transcostal wall projected in an image plane of the phased array by taking into consideration a position and direction of the phased array and making it possible to deactivate elements of the phased array in accordance with the position of the elements with regard to the position of the projected image of the transcostal wall; a positioning system to control the position of a focussed zone of a beam of focussed ultrasound signals on the targeted zone, a monitoring system to measure a temperature and tissue deformation in the targeted zone; and a device for measuring a level of cavitation in the targeted zone.

A system for assisting guiding an endovascular instrument in vascular structures of an anatomical region of interest of a patient. This system includes an imaging device for capturing three-dimensional images of parts of the body of a patient, a programmable device and a viewing unit. The imaging device captures partially superposed fluoroscopic images of the region, and the programmable device forms a first augmented image, representative of a complete panorama of bones of the region, and cooperates with the imaging device to obtain a second augmented image including a representation of the vascular structures of the region. The imaging device captures a current fluoroscopic image of a part of the region, and the programmable device registers the current fluoroscopic image with respect to the first augmented image and locates and displays, on the viewing unit, an image region corresponding to the current fluoroscopic image in the second augmented image.

A method for calculating during use the geometric parameters of an x-ray imaging system, an object or a patient to be observed being placed between the x-ray source and a detector of x-rays having passed through the object or patient, wherein it includes at least the following steps: detecting at least one marker on the object or the patient or in proximity to the object, the marker being of unknown 3D position, acquiring a plurality of 2D images for a plurality of viewpoints of the imaging system, detecting the position of at least one marker in each of the acquired 2D images, estimating the projection matrices corresponding to the projections of the object at various viewing angles and reconstructing in 3D the position of a marker on the basis of the estimation of the projection matrices.

A force sensed surface scanning system (20) employs a scanning robot (41) and a surface scanning controller (50). The scanning robot (41) includes a surface scanning end-effector (43) for generating force sensing data informative of a contact force applied by the surface scanning end-effector (43) to an anatomical organ. In operation, the surface scanning controller (50) controls a surface scanning of the anatomical organ by the surface scanning end-effector (43) including the surface scanning end-effector (43) generating the force sensing data, and further constructs an intraoperative volume model of the anatomical organ responsive to the force sensing data generated by the surface scanning end-effector (43) indicating a defined surface deformation offset of the anatomical organ.

Systems and methods for monitoring food intake include an air pressure sensor for detecting ear canal deformation, according to some implementations. For example, the air pressure sensor detects a change in air pressure in the ear canal resulting from mandible movement. Other implementations include systems and methods for monitoring food intake that include a temporalis muscle activity sensor for detecting temporalis muscle activity, wherein at least a portion of the temporalis muscle activity sensor is coupled adjacent a temple portion of eyeglasses and disposed between the temple tip and the frame end piece. The temporalis muscle activity sensor may include an accelerometer, for example, for detecting movement of the temple portion due to mandibular movement from chewing.

Cutting tools, systems and methods for navigated procedures are provided. A cutting tool (e.g. oscillating blade, etc.) for a power tool has an optically trackable feature in a defined positional relationship relative to a cutting feature of the cutting tool. The trackable feature may include reflective material applied to a surface (e.g. a recessed blade surface). The trackable feature is be imaged by a camera integral with or attached to the power tool and provided to a computing unit of a navigation system to determine a relative pose of the cutting feature and camera. The camera may also track a patient's bone such that the computing unit may determine a relative position of the bone and camera. The unit then computes a relative pose of the cutting feature with respect to the patient's bone and provides same for determining display information and/or to a robotic controller for procedural control.

The present disclosure relates to a tourniquet 1 comprising a tension sensor 8 and loop portion 4 ensuring that an intended pressure has been achieved on a body part on which the tourniquet is applied. The tension sensor comprises a plurality of cuts 20 arranged in a predetermined pattern. The present disclosure also relates to a dispenser comprising a plurality of such tourniquets, and a kit comprising a tourniquet.

The invention relates to an assembly for use in minimally invasive surgical procedures, including bone implant fixation procedures. The assembly is configured to provide a faster and more accurate measurement of depth of holes for placement of bone screws and fasteners. The assembly includes a guidewire having a deployable distal hook member configured to securely anchor into a desired position relative to a hole drilled in a bone and thereby provide an accurate datum for a measuring instrument for determining a depth of the hole for subsequent screw placement. The assembly further includes a surgical depth instrument to cooperatively function with the guidewire and obtain one or more measurements while operably coupled to the guidewire.

The disclosure provides tissue force sensor systems and methods for tissues, e.g., laryngeal tissue. The systems include a top housing including on an upper side an attachment mechanism for connecting the top housing to a medical device, e.g., a laryngoscope, and on a lower side a first cavity for receiving a top portion of a force measurement device such as a load cell; a bottom housing including on a lower side an attachment mechanism for connecting the bottom housing to a handle, holding system, or suspension system for holding or supporting the medical device, and on an upper side a second cavity for receiving a bottom portion of the force measurement device; and an attachment device for connecting the top housing to the bottom housing.
