Patent number: 11723689Abstract: 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: GrantFiled: December 7, 2020Date of Patent: August 15, 2023Assignee: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz A.

Publication number: 20230218312Abstract: 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: March 7, 2023Publication date: July 13, 2023Inventors: Arkadiusz A. Strokosz, David T. Okihisa, Steven E. Decker, Phillip De Alday, Scott V. Taylor, Henry Kahle

Patent number: 11357524Abstract: The tissue retrieval system deploys a tissue bag at the surgical site. The bag is supported by the system as tissue is placed within the bag and is closed to isolate the collected tissue and allow the bag and collected tissue to be removed from the body. The bag can be reopened and re-closed as desired through use of a guide bead and cord. The bead also facilitates removal of the collected tissue.Type: GrantFiled: December 9, 2019Date of Patent: June 14, 2022Assignee: Applied Medical Resources CorporationInventors: Henry Kahle, Gary M.

Publication number: 20220054154Abstract: A tissue retrieval system can include a tissue retrieval bag with an elongate profile. The tissue retrieval bag can have a relatively large volume, but be rollable to a stowed configuration to fit in a relatively small diameter introducer. The tissue retrieval system can include one or more support arms coupled to the tissue retrieval bag, the support arms biased to position the tissue retrieval bag in an access position once deployed from the introducer. A tissue retrieval system can have a hybrid tissue retrieval bag including material properties that vary along the depth of the bag from an open end to a closed end. A tissue retrieval bag can be used in conjunction with an introducer, or as a stand alone tissue retrieval bag.Type: ApplicationFiled: November 4, 2021Publication date: February 24, 2022Inventors: Scott V.

Patent number: 10568658Abstract: 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: GrantFiled: April 17, 2017Date of Patent: February 25, 2020Assignee: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz A.
