摘要： A surgical end effector assembly includes first and second jaw members configured to grasp tissue. At least one of the jaw members defines a channel. A cutting element reciprocates through the channel to cut grasped tissue. The cutting element may include a first bevel defined along a first portion of a distal edge on a first side surface of the cutting element and a second bevel defined along a second portion of the distal edge on a second side surface of the cutting element. The first and second portions of the distal edge are sharpened to facilitate cutting tissue upon distal advancement of the cutting element. Alternatively or additionally, the cutting element may include a proximal body and a distal fin defining a height greater than a height of the proximal body and including a thinned portion defining a depression within a first side surface thereof.

摘要： A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof, the distal end including an end effector assembly having a pair of opposing jaw members operably coupled thereto. One or both of the jaw members is moveable between open and closed positions for clamping tissue with a closure pressure. One or both of the jaw members connects to a generator that provides energy thereto in accordance with a sealing algorithm upon activation thereof. An anti-backdrive mechanism is coupled to the end effector assembly and includes a drive shaft coupled at one end to a solenoid and another end that engages one of the jaw members upon extension thereof to provide additional closure pressure between the jaw members. The drive shaft is extendible by the solenoid to extend the drive shaft in response to tissue expansion during sealing based on the sealing algorithm.

摘要： A jaw member for a surgical instrument includes an outer housing having a sealing plate operably coupled thereon including an upper knife channel defined therethrough and extending therealong. A pair of opposing jaw flanges is configured to operably couple to a corresponding pair of jaw flanges of an opposing jaw member. An insulative insert is disposed within the outer housing and includes opposing sidewalls and a connector portion which define an engagement channel and a lower knife channel in vertical registration with the upper knife channel, the upper and lower knife channels configured to receive a knife of a knife assembly, the engagement channel configured to receive a tube of the knife assembly. A top plate is engaged between the jaw flanges, a portion of the top plate is configured to extend across the engagement channel and retain the tube within the engagement channel during translation of the knife assembly.

摘要： A surgical end effector assembly includes first and second jaw members configured to grasp tissue. Each of the first and second jaw members includes a proximal flange portion and a distal body portion. The proximal flange portions are pivotably coupled to one another to move the distal body portions between a spaced-apart position and an approximated position.

摘要： A jaw member of a surgical instrument includes a structural frame, an insulative spacer supported on the structural frame, an electrically conductive tissue contacting plate supported on the insulative spacer, and a lead wire. The spacer defines a pocket at an upper portion thereof and includes a channel extending from the pocket, through the spacer, to a bottom portion of the spacer. The channel defines a substantially U-shaped configuration having first and second radiused corners at the bottom portion of the spacer. The lead wire is attached to an underside of the plate at an attachment point within the pocket and extends distally from the attachment point into the channel, through the channel, over the first and second radiused corners, and proximally from the jaw member. The lead wire is adapted to connect to a source of energy to energize the plate for treating tissue.

摘要： 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/cm2 to about 16 kg/cm2. 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.

摘要： A robotic surgical instrument includes a housing, a shaft assembly extending distally from the housing, and an end effector assembly. The shaft assembly has a proximal segment coupled to the housing, a clevis supporting the end effector assembly, and at least one articulating link pivotably coupled to and interconnecting the proximal segment and the clevis such that the end effector assembly is configured to articulate relative to the proximal segment via the at least one articulating link in at least two directions.

摘要： An articulating electrosurgical instrument includes a housing having an elongated shaft extending therefrom and a wrist assembly operably supported to a distal end of the elongated shaft and configured to support an end effector assembly at distal end thereof. The wrist assembly includes a proximal link operably coupled to the distal end of the elongated shaft, a distal link operably coupled to the end effector assembly, and a central link operably coupled between the proximal link and the distal link. A transition lumen is configured to be received within the distal link, central link and proximal link. The transition lumen includes a helical passageway defined therein configured to guide a blade rod therethrough for operable engagement with a blade disposed within the end effector assembly.

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/cm2 to about 16 kg/cm2. 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.
