Publication number: 20150105728Abstract: The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a shaft extending along an axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers.Type: ApplicationFiled: December 16, 2014Publication date: April 16, 2015Inventors: Henry Kahle, Arkadiusz A.

Patent number: 8608769Abstract: A surgical access device comprising a tissue separating obturator suitable for connection with a cannula is disclosed. The obturator includes an elongate shaft having a transparent distal tip. The elongate shaft extends along a longitudinal axis and defines a lumen. The transparent distal tip has a tapered configuration and includes an inner surface and an outer surface adapted for penetrating tissue. The lumen is sized and configured to receive an optical instrument such as a laparoscope. The surgical access device further includes a scope lock at the proximal end of the shaft portion. The lock includes a multi-fingered collet coaxial with the lumen. The inner diameter of the collet is smaller than an outer diameter of the optical instrument and the fingers of the collet provide frictional engagement with the outer diameter of the optical instrument that is inserted into the lumen of the obturator.Type: GrantFiled: August 3, 2012Date of Patent: December 17, 2013Assignee: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz A.

Publication number: 20130324912Abstract: A surgical access system comprises a trocar, an insufflating optical obturator slidably insertable into the trocar, and a laparoscope slidably insertable into the obturator. A distal end of the obturator comprises a tip, at least a portion of which comprises a wall with a generally uniform thickness comprising a transparent material. At least one vent hole disposed at the obturator tip is fluidly connected to a gas flow channel defined by an interior surface of the obturator and the laparoscope, which is fluidly connected to an insufflation gas inlet disposed at a proximal end of the trocar. Improved optical characteristics of the trocar system permit precise and accurate visual placement thereof into a body cavity. Accordingly the access system is suitable as a first entry surgical access system. Embodiments of the trocar access are also useful for drug delivery, and/or for fluid and/or tissue aspiration.Type: ApplicationFiled: August 8, 2013Publication date: December 5, 2013Applicant: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz Strokosz, Scott V.

Publication number: 20110093005Abstract: Surgical tools that can be used in single port laparoscopic procedures can include a low-profile handle assembly to minimize tool interference adjacent the incision site. For example, a handle assembly for a surgical instrument can have a generally in-line configuration extending linearly along a central longitudinal axis of an elongate shaft of the instrument. A linkage mechanism including a trigger, an actuation link, and an actuation shaft can be positioned within the in-line handle. The linkage mechanism can be pivoted between an open position in which end effectors of the instrument are open and a toggle position in which the end effectors are locked closed. A locking mechanism such as a ratchet mechanism can also be used to lock the end effectors. A surgical dissector can include gripping jaws having a curved profile or an angled elongate shaft to minimize tool interference and maximize visibility within a procedure site.Type: ApplicationFiled: October 11, 2010Publication date: April 21, 2011Applicant: Applied Medical Resources CorporationInventors: Arkadiusz A.

Publication number: 20060161190Abstract: The invention is directed to a surgical instrument including a handle assembly and a shaft assembly. The handle assembly further includes a fixed handle and a pivoting handle. The shaft assembly extends from the handle assembly and further includes an outer tube and an inner actuation rod that slides coaxially with the outer tube. The shaft assembly includes a rotatable knob to provide 360° rotation. The actuation rod has a proximal end and a distal end; the proximal end has a ball end that couples with the pivoting handle to form a rotatable ball-and-socket joint. The outer tube is formed of plastic and fits over the actuation rod to function as an electrical insulator.Type: ApplicationFiled: January 18, 2006Publication date: July 20, 2006Inventors: Donald Gadberry, Gary Johnson, Jeremy Albrecht, David Okihisa, Said Hilal, Arkadiusz Strokosz

Patent number: 5868771Abstract: A scalpel blade sheath which encloses and retains a scalpel blade therein. A scalpel handle is selectively inserted into the sheath whereby the scalpel blade is securely attached to the scalpel handle in preparation for cutting operations. The sheath is selectively slipped onto the scalpel handle to expose the blade for the cutting operation. The sheath is repositioned over the scalpel blade to protect the blade (and the user thereof) when the cutting operation is concluded. When the blade is to be removed from the scalpel handle after the cutting operation, the scalpel blade is retained within the sheath for safe and sanitary disposal of the blade and the sheath.Type: GrantFiled: July 25, 1997Date of Patent: February 9, 1999Assignee: Pabban Development, Inc.Inventors: H.
