A positioning system comprising a first working element having a first tubular shaft, a second working element having a second tubular shaft, an arcuate element having a holding element and an arcuate rail, wherein the arcuate rail is disposed on the holding element and the holding element is adapted to be fixed on the receiving section by means of a fastening element, and a guiding element having a holding section and a guiding section, wherein the holding section is guided on the rail and the guiding section receives the second shaft, the holding section having a locking element securing the guiding element to the rail, wherein the locking element in a locking position blocks displacement of the holding section in a transverse direction and in a release position allows displacement of the holding section in the transverse direction.

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a grommet which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the grommet and the clip.

One or more example embodiments of the present invention relates in one aspect to a computer-implemented method for providing a configuration information for a laser guidance system for a medical intervention, comprising receiving laser projection data regarding a laser projection geometry of the laser guidance system; receiving 3D model data regarding a surface, the surface being located within an effective range of the laser guidance system; calculating shadowing data regarding a shadowing effect of the surface on the laser projection geometry based on the laser projection data and the 3D model data; selecting the configuration information based on the shadowing data, the configuration information being indicative of a configuration of the laser guidance system for visualizing a planned path of an instrument for the medical intervention; and providing the configuration information.

Disclosed herein is a magnetic signature imprinting system including an imprinting device and a medical device including ferrous elements. The imprinting device includes an active area having a magnet moving system, one or more sensors, and a console. The magnet moving system is configured to change the location or orientation of one or more magnets to generate one or more magnetic fields to imprint a magnetic signature. The one or more sensors are configured to detect one or more characteristics of the medical device and the console is in communication with the magnet moving system and the one or more sensors.

A craniocerebral operation passage is provided, including a guide device, a trocar, and an outer sheath. The guide device is used for penetrating into the brain of a patient; a connection hole is provided in the middle of the trocar and passes through the trocar in a direction of a central axis of the trocar; the connection hole and the trocar are coaxially disposed; the trocar can sheathe on a periphery of the guide device through the connection hole and can slide in a lengthwise direction of the guide device; the outer sheath is internally hollow for providing an operation passage; and the outer sheath can sheathe the periphery of the trocar. The craniocerebral operation passage is accurately located and can effectively protect brain tissues of a patient.

An ultrasonic imaging configuration rendering an image based on a reflected beam aligned with a needle insertion axis provides enhanced images and guidance. A percutaneous insertion guidance device for ultrasonic (US) imaging includes an US transducer and a reflector for redirecting imaging signals between the transducer and an imaged region. An enclosure or bracket is adapted to support the reflector at a predetermined angle based on a surgical target in the imaged region such that a forward beam direction from the transducer reflects in a direction of the needle insertion as the needle passes through a discontinuity or slot in the reflector. The resulting return signal is based on an axial alignment of the US signals with the needle travel towards the surgical target.

A needle guide comprising a base to which a pair of horizontal slide bars are secured, the horizontal slide bars including a channel opening running between the bars, a needle stabilizer with a central tube is slideably engaged with the pair of horizontal slide bars, wherein the needle stabilizer extends through the channel opening and has the ability to change positions along a length of the horizontal slide bar, an angular ruler is secured to the base and located proximal to the needle stabilizer to allow accurate adjustment of the angle of the externally adjustable needle guide and one or more virtual visualization bars to aid in visualization using radiography, ultrasound, or magnetic resonance (or any other medical imaging technology) to visualize the virtual visualization bars.

A biopsy needle for collecting a tissue specimen includes an outer cannula and an inner tube received within the outer cannula and configured to receive a stylet. The outer cannula is fixedly coupled to a needle holder that is coupled to and moves with a movable base that is axially movable within the handle housing. An inner driven structure (curvilinear part) is configured to selectively engage the movable base and travel therewith in a first stage of operation and in a second stage of operation in which the inner driven structure is disengaged from the movable base, the inner driven structure is driven along the movable base which is held in a stationary position. The coupling between the inner driven structure and the inner tube is such that the axial driving of the inner driven structure imparts rotation to the inner tube relative to the outer cannula.

The present invention is a Miniature Vein Enhancer, for use in imaging the subcutaneous veins of a target area of a patient by a practitioner. The miniature vein enhancer includes a Miniature Projection Head that is secured to a tourniquet, where the tourniquet may be mounted to the bicep of a patient. The Miniature Projection Head includes a housing, and apparatus that images subcutaneous veins of the target area, and projects the image(s) of the veins onto the target area to overlie the subcutaneous veins, which aids the practitioner in pinpointing a vein location for a venipuncture procedure such as an intravenous drip, blood test, and the like.

A medical device for injecting fat while simultaneously allowing the injection site to be viewed with ultrasound. The device may comprise a handle with a front portion and a rear portion, a cannula having a cannula tip, extending from the front portion of the handle, and an ultrasound probe attached to the handle, the ultrasound probe comprising an ultrasound head. The ultrasound head is aligned with and spaced apart from the cannula tip, and remains so aligned during the injection process so that the injection area may be continuously viewed during the procedure.
