The present invention involves systems (20) and related methods for performing percutaneous pedicle integrity assessments involving the use of neurophysiology. The fundamental method steps for performing the percutaneous pedicle integrity assessments include (a) percutaneously introducing an insulation member to a pedicle target site; (b) establishing electrical communication between a stimulation element and an interior of a pedicle screw pilot hole; (c) applying a stimulation signal to the stimulation element; and (d) monitoring to assess whether nerves adjacent the pedicle are innervating as a result of the step of applying the stimulation signal to the stimulation element.

The invention aims to optimise the handling characteristics of a rotating surgical instrument, used to create a cavity in bone material. This is achieved by an ultrasonic transducer which is located in said instrument and which can transmit and receive ultrasonic waves. The ultrasonic transducer can be connected to an ultrasonic generator and to a receiving device which generates signals, according to the intensity of the ultrasonic radiation received by the ultrasonic transducer and according to the time period between emission of the ultrasonic radiation and the reception of reflected ultrasonic radiation. Said signals provide measurements for determining the characteristics of the bone material in the direction of the radiation emission.

According to one embodiment, a medical insertion apparatus includes a screw nail body inserted into a human body and an electrode which is provided in the screw nail body and includes an externally exposed portion. Here, a through hole may be formed in the screw nail body or the electrode. According to one embodiment, a medical insertion apparatus includes a screw nail body inserted into a human body and an electrode which is provided in the screw nail body and exposed outside the screw nail body. Here, the screw nail body and the electrode may be provided as a combinable or separable structure. According to one embodiment, a medical insertion apparatus includes a screw nail body inserted into a human body, a driver engaged with the screw nail body to tighten or loosen the screw nail body, and a conductor portion which may be provided in the screw nail body or the driver and may include an externally exposed portion. According to one embodiment, a medical insertion apparatus includes a screw nail body inserted into a human body, a driver engaged with the screw nail body to tighten or loosen the screw nail body, and a conductor portion which is provided in the screw nail body and the driver and includes a portion exposed outward at one side of the screw nail body. Here, the screw nail body and the conductor portion disposed in the driver may be electrically connected to each other.

A system and method for developing customized apparatus for use in one or more surgical procedures is disclosed. The system and method incorporates a patient's unique anatomical features or morphology, which may be derived from capturing MRI data or CT data, to fabricate at least one custom apparatus. According to a preferred embodiment, the customized apparatus comprises a plurality of complementary surfaces based on a plurality of data points from the MRI or CT data. Thus, each apparatus may be matched in duplicate and oriented around the patient's own anatomy, and may further provide any desired axial alignments or insertional trajectories. In an alternate embodiment, the apparatus may further be aligned and/or matched with at least one other apparatus used during the surgical procedure.

An apparatus for cleansing wounds in which irrigant fluid containing one or more physiologically active components from a means for supplying physiologically active agents from cells or tissue to the wound, e.g. an irrigant reservoir connected to a container that contains a cell or tissue component, in turn connected to a supply tube, connected to a conformable wound dressing and wound exudate from the dressing are moved by a device (which may be a single pump or two or more pumps) for moving fluid through a flow path which passes through the dressing and a means for providing simultaneous aspiration and irrigation of the wound. The latter removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing from cells or tissue and the physiologically active components in therapeutically active amounts in a precise and time-controlled manner over the wound bed.

There is provided an ultrasonic probe for supporting spine surgery which can execute both inspection by tactile sense and inspection by ultrasound diagnosis. A front-end component is provided at a front end of an insertion unit. The front-end component comprises a metal component and a resin component, and the metal component comprises a tactile member and an anchor. The resin component comprises a cap portion and a surrounding portion. An insertion portion in the front-end component is inserted into a front end portion of a pipe. The anchor and the front end portion are in close proximity with a certain distance therebetween, such that insulation is secured and vibration transmitted from a head can be transmitted from the anchor to the pipe in a superior manner.
