International Classification:

A61B 18/04
H01R 43/16

US Classification:

606 33, 29874

Abstract:

An end effector assembly having first and second jaw members is provided where one or both of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes an inwardly-facing surface having a slot defined therein and a wire having an insulative coating. A seal plate has at least one protrusion that is configured to be disposed in the slot. The at least one protrusion of the seal plate is configured to displace the insulative coating from the wire thereby forming an electrical connection therewith when the at least one protrusion is disposed in the slot.

International Classification:

B23P 17/04

US Classification:

2940705

Abstract:

A method for manufacturing an end effector assembly is provided. The method includes grasping a gap-setting gauge between first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second position proximate tissue and setting the first and second jaw members such that in the approximated position the jaw members cooperate to define a gap distance between the jaw members equivalent to the thickness of the gap-setting gauge such that when positioning tissue between the jaw members full approximation of the jaws is limited to the gap distance.

International Classification:

A61B 18/14
A61B 18/12

Abstract:

A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof including an end effector assembly having opposing first and second jaw members operably coupled thereto. One of the jaw members moveable between open and closed positions for clamping tissue with a closure pressure within the range of about 3 kg/cmto about 16 kg/cm. The jaw members are adapted to connect to a generator for providing energy thereto in accordance with a sealing algorithm. An anti-backdrive mechanism is associated with the end effector assembly and includes: a drive shaft coupled to a controller and a screw on opposite ends, the screw configured to engage one of the jaw members upon extension thereof to provide additional closure pressure therebetween. The drive shaft is rotatable by the controller to extend the screw in response to tissue expansion during sealing based on the sealing algorithm.

International Classification:

A61B 18/14
A61B 18/12

Abstract:

A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof having an end effector assembly including a pair of opposing first and second jaw members operably coupled thereto. A drive assembly is disposed within the housing and is configured to move the jaw members upon actuation thereof between an open position and a closed position for clamping tissue with a closure pressure within the range of about 3 kg/cmto about 16 kg/cm. An anti-backdrive assembly is operably disposed within the housing and includes a drive wedge. A solenoid controller is operably coupled to the drive wedge and is configured to selectively move the drive wedge into the drive assembly upon activation thereof to increase the closure pressure between the jaw members in response to tissue expansion during sealing.

Abstract:

A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

Abstract:

A surgical instrument includes an elongated shaft supporting an end effector assembly, a sheath slidably disposed about the elongated shaft and the end effector assembly, and a housing disposed at a proximal end portion of the elongated shaft. Inflow, outflow, and common tubes extend into the housing. A manifold is disposed within the housing and defines an inflow port fluidly coupled to the inflow tube, and outflow port fluidly coupled to the outflow tube, and a common tube port fluidly coupled to the common tube. First and second valve assemblies are disposed within the housing and operably coupled to the manifold. The first valve assembly is configured to selectively control a flow of fluid from the inflow tube to the interior of the sheath, and the second valve assembly is configured to selectively control a flow of fluid from the interior of the sheath to the outflow tube.
