  • Patent number: 5599348
    Abstract: A trocar assembly includes an elongate trocar device and a surrounding cannula. The trocar device incorporates an electrosurgical cutting element which is used to make a guide hole for the cannula and thus enables the remainder of the trocar assembly to enlarge the puncture. An electronic control circuit senses the current flow to the cutting element and, when the trocar device breaks through the wall of the organ being cut, this circuit cuts off the connection to the associated electrosurgical generator. Further control circuitry prevents a surgeon from resuming electrosurgery until a predetermined time period has elapsed. Multiple trocars of different diameters are provided for the same assembly.

  • Patent number: 5599351
    Abstract: Scalpel constructions are shown in which shipping of the scalpel occurs with the blade retracted, surgeon usage enables exposure of the scalpel blade from required cutting during surgery, and finally and upon completed use of the scalpel, one-way retraction of the scalpel into a "sharp-safe" blade covering disposition can occur. Thereafter, upon scalpel discard, the cutting edge of the scalpel is safely shielded and inhibited from further intentional or inadvertent cutting. A first design includes scalpel reciprocation along a handle against a detent for shipping with the blade within the handle, use with the blade exposed from the handle, and one-way retraction into the handle immediately prior to discard. A second design includes a handle folding across the scalpel body with a sleeve having a first position for covering the blade during shipping, a second position for holding the blade extended and exposed for surgery, and a third position for permanently locking about the scalpel blade after use.

  • Patent number: 5591188
    Abstract: A surgical instrument serves to insert a trocar needle into the bone marrow of a patient for connection of a syringe, an infusion set or the like. The instrument includes a cylindrical housing containing a sliding bolt and the trocar needle configured to be forcefully shot through the bone material into the marrow by release of a compressed helical spring. The bolt holds the rear end of the needle in a releasable grip permitting the needle to be released and to remain in the bone. The helical spring is positioned in the rear of the housing and of the bolt and is held in compressed state by a catch which is releasable by pressure on a trigger. This shoots the bolt and the needle forwards, a collar in the housing stopping the bolt sharply and allowing the needle to be released from the device after its penetration and to be connected to a syringe or an infusion set for intraosseous injection, infusion or other treatment.

  • Patent number: 5569298
    Abstract: A surgical instrument has a hollow elongated shaft for insertion into the body, the shaft having a longitudinal axis and supporting a pair of interacting pivotable jaws on its distal end and being connected at its proximal end to a first movable component of an operating handle, with a reciprocable rod located within the shaft. The rod is connected to a second movable component of the handle for reciprocation within the shaft when the first and second components are moved relative to each other. The jaws are pivotally connected by a pivot pin supported on the shaft transversely to the axis. Each of the jaws has a proximal end extending proximally from the pivot pin. Each of the proximal ends is provided with an elongated opening therethrough, each the openings forming an elongated slot oriented at an oblique angle relative to the longitudinal axis of the shaft. The reciprocable rod has a distal end extending into each slot whereby reciprocation of the rod causes the jaws to open and close.

  • Patent number: 5562619
    Abstract: For achieving, e.g., an improved electrophysiology catheter for examination of the heart, or a catheter accessing the brain, the invention, in one aspect, features an elongated wound wire coil extending through the hollow catheter body of a steerable catheter, the coil constructed and arranged to enable the catheter body to withstand reactive compressive load without distortion during application of tension on the pull wire and to transmit torque from the proximal to the distal tip portion of the catheter to enhance fidelity of rotational positioning of the distal tip in response to rotational orientation of the proximal portion of the catheter. The coil is shown in frictional torque-transmitting relationship with the interior of the hollow shaft substantially along the common length of the catheter body when the catheter is bent. Steerable catheters with augmented throw for one-handed operation and important improvements in construction features are also shown.

  • Patent number: 5556410
    Abstract: A surgical needle including a cannula, hook-wire and reinforcement member for use in the manual location and marking of a lesion in a mass of soft tissue. The cannula rigidly supports the hook-wire during insertion into the soft tissue, and has a substantially cylindrical, hollow shaft and a cutting point located at an insertion end. The surgical needle further includes an anchor for restrainably locating the hook-wire proximate the lesion which is capable of springedly assuming a substantially acute angle relative to the remainder of the hook-wire. Reinforcement minimizes the potential for breakage of the hook-wire within the mass of soft tissue, after extension of the hook-wire beyond the insertion end of the cannula; in which the hook-wire is substantially D-shaped and closely approximates the diameter of the substantially cylindrical, hollow shaft; maximizing the structural size and integrity of the hook-wire to minimize the occurrence of breakage.
