Patent number: 8430876Abstract: An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.Type: GrantFiled: August 27, 2009Date of Patent: April 30, 2013Assignee: Tyco Healthcare Group LPInventors: John J. Kappus, Thomas J. Gerhardt, Wayne Siebrecht, Larry Johnson

Patent number: 8343151Abstract: A forceps includes a housing having a shaft extending therefrom. The shaft has an end effector assembly that defines a longitudinal axis therethrough. The end effector assembly includes first and second jaw members disposed in opposed relation and moveable from a first, open position to a second, closed position for grasping tissue therebetween and a knife. One or more jaw members include knife blade channels defined therein. Each knife blade channel includes a polygonal longitudinal cross-section defined therein. The knife includes a knife edge and a knife base. The knife base includes a corresponding polygonal longitudinal cross-section. The knife is configured to translate through the knife blade channels and the knife base is configured to slidingly engage the knife base channel having the polygonal cross section upon translation of the knife. In embodiments, the knife blade channel and the knife base have a T-shaped longitudinal cross-section.Type: GrantFiled: October 9, 2009Date of Patent: January 1, 2013Assignee: Covidien LPInventors: Wayne Siebrecht, Thomas J.

Publication number: 20120296371Abstract: A modular shaft assembly for use with a variety of different endoscopic forceps each having a housing includes a handle assembly and one or more moveable handles. The modular shaft assembly also includes a shaft having proximal and distal ends and an end effector assembly including a pair of jaw members attached to the distal end thereof. The shaft and a universal drive assembly are attached at the proximal end of the shaft. The universal drive assembly is operably engageable with the handle assemblies of the variety of different endoscopic forceps such that actuation of the one or more movable handles of any of the variety of different forceps causes the universal drive assembly to actuate the jaw members to move between an open position wherein the jaw members are disposed in spaced relation relative to one another to a closed position for grasping tissue therebetween.Type: ApplicationFiled: May 14, 2012Publication date: November 22, 2012Applicant: TYCO HEALTHCARE GROUP LPInventors: John J.

Publication number: 20120271254Abstract: Described are embodiments of a canister, system, and method of filtering fat. Embodiments include a sidewall that defines a volume, a filter with a screen, a first port, a second port, and at least one vane which allows for manual agitation of lipoaspirate within the volume. The first port is used to draw fluid from below the filter, forcing excess fluid in the lipoaspirate to be quickly extracted. The vane allows the lipoaspirate to be repeatedly drawn over the filter to aide in removing of liquids from fat in the lipoaspirate. The treated fat may then be removed from the volume through an outlet port and reinjected into a patient.Type: ApplicationFiled: February 22, 2012Publication date: October 25, 2012Inventors: Mark E.

Publication number: 20120109187Abstract: An endoscopic forceps is provided and includes a housing having a handle assembly including a movable handle having a mechanical interface disposed thereon. An end effector assembly connected to a distal end of the shaft includes a pair of first and second jaw members movable relative to one another from an open to a clamping position. A drive assembly includes a resilient member. A lock assembly is pivotably coupled to the housing and in operative communication with the movable handle. The lock assembly is movable with the handle assembly. The mechanical interface moves along the lock assembly when the movable handle is moved proximally causing the lock assembly to rotate about the pivot point and into communication with the resilient member such that the resilient member is prevented from moving distally against the bias provided therefrom such that the first and second jaw members remain in the clamping position.Type: ApplicationFiled: October 29, 2010Publication date: May 3, 2012Inventors: Thomas J. Gerhardt, JR., Wayne Siebrecht, Keir Hart

Publication number: 20120078234Abstract: Described are embodiments that include a device with a motor that when connected to a cannula rotates the cannula while removing adipose tissue from a surgical site. The device provides a direct pathway, for aspirated adipose tissue, from a tip of the cannula to a location where tubing is attached to the device. The pathway does not pass through the motor that provides the angular rotation of the cannula. Instead, the path for the adipose tissue passes through a removable coupler that is connected to the cannula. The embodiments provide a cannula that rotates but also has a direct flow path for adipose tissue that does not pass through the motor.Type: ApplicationFiled: September 29, 2011Publication date: March 29, 2012Inventors: Adnan I. Merchant, David B. Mogill, Wayne A. Siebrecht

Publication number: 20110054471Abstract: A surgical instrument is provided. The surgical instrument includes a housing having a shaft that extends therefrom that defines a longitudinal axis therethrough. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members. The surgical instrument includes a handle assembly that includes a movable handle movable relative to a fixed handle operable to impart movement of the jaw members relative to one another.
