Publication number: 20170042570Abstract: The present invention provides a system and method for inserting a surgical port to minimize trauma. The system includes an access port and a guiding mechanism on the distal end of the access port, wherein the guiding mechanism has an adaptive atraumatic tip. The system also includes an introducer probe with a handle on the proximal end of the introducer probe, an atraumatic tip on the distal end of the introducer probe and a flexible body for insertion through the access port, the flexible body comprising one or more bendable elbows along the length of the introducer probe, wherein the introducer slidably engages the interior of the surgical access port to define an access path. The method includes inserting an access port down a sulcal path, inserting an introducer probe through the access port, and navigating the sulcal path with the introducer to the target.Type: ApplicationFiled: March 12, 2015Publication date: February 16, 2017Inventors: Cameron Anthony PIRON, Michael Frank Gunter WOOD, Murugathas YUWARAJ, Joshua Lee RICHMOND

Publication number: 20170042571Abstract: In one representative embodiment, a gripping and pushing device for a medical instrument comprises an elongated main body defining a lumen. The elongated main body comprises one or more deflectable portions that can be pressed radially inwardly toward a shaft of the medical instrument extending through the lumen. One or more elastomeric gripping layers can be secured to the inner surface of a respective deflectable portion at axially spaced apart attachment locations. The one or more gripping layers are axially deformable relative to the one or more deflectable portions between the attachment locations when manual pressure is applied to the one or more deflectable portions to press the one or more gripping layers against the shaft and move the shaft longitudinally into a patient's body.Type: ApplicationFiled: August 9, 2016Publication date: February 16, 2017Inventor: Tamir S. Levi

Publication number: 20170042573Abstract: A Veress needle is modified to receive a forward-looking miniature videoscope through the cannula of an insufflation tube of the Veress needle. The modified instrument enables direct viewing of progress of the instrument through tissue to the peritoneal cavity of a patient, for proper location of the needle and insufflation of the cavity via the needle. The videoscope has an elongated shaft of smaller diameter than the cannula of the insufflation tube for passage of insufflation gas with the scope in place. In another embodiment a needle is fitted with a miniature videoscope to provide the same function, with the needle's cannula serving as an insufflation tube.Type: ApplicationFiled: November 6, 2015Publication date: February 16, 2017Inventors: Odyssefs Ath.

Publication number: 20170042574Abstract: The present invention is an orthopedic trigger apparatus including a rack assembly, a trigger housing assembly and a trigger assembly. The rack assembly includes a linear rack rotatably connected to a first handle of an orthopedic instrument. The trigger housing assembly includes a trigger housing connected to a second handle of the orthopedic instrument, with a rack engagement cylinder and a spring enclosed within the trigger housing. The rack engagement cylinder includes a toothed rack. The spring contacts a second surface of the toothed rack stop, biasing a first pawled surface into meshing with the rack and preventing the rack from sliding through the trigger housing in more than one direction. Actuating the trigger assembly causes an actuator protrusion on the trigger to press against the rack engagement cylinder, moving the first pawled surface of the toothed rack stop away from the rack and allowing the rack to slide freely.Type: ApplicationFiled: September 11, 2015Publication date: February 16, 2017Inventor: Andrew Rajek

Publication number: 20170042578Abstract: The skull clamp system with pressure limiting and alarm systems includes at least one and preferably multiple inwardly power driven immobilizing pins adjustably engaging the skull of a patient. The pin power drive systems includes at least one sensor capable of sensing the degree of back pressure on the pin from contact of the pin against the bone of the patient, the sensor being capable of signaling the drive system to stop when the sensor detects a preselected degree of back pressure. The sensor is also capable of signaling an alarm to warn of any reduction of pressure applied to the pins that might result from pin slippage.Type: ApplicationFiled: October 26, 2016Publication date: February 16, 2017Inventors: Clifford T.
