Instrument for Selectively Grabbing and Cutting Tissue
A surgical instrument configured for both grasping and cutting operations has a shaft with a push rod extending through it. An end effector on the shaft has a grasping jaw, a cutting jaw, and an intermediate jaw. The grasping jaw forms a grasping device with the intermediate jaw, and the cutting jaw forming a cutting device with the intermediate member. A segment of the shaft proximal to the end effector is axially rotatable between a first position, in which the push rod can advance through the segment to actuate the cutting device, and a second position in which the push rod can advance through the segment to actuate the grasping device
Firing assembly comprising a multiple failed-state fuse
Surgical instruments are disclosed comprising a firing assembly including a fuse having a plurality of operating states.
THERMAL MECHANISM TO PREVENT REPROCESSING OR REUSE OF MECHANICAL SURGICAL DEVICES
A surgical apparatus comprising: a mechanism that is configured to perform an operational motion of the surgical apparatus; and at least one transformation member having an original shape and a deformed shape, the at least one transformation member connecting the mechanism together, when the at least one transformation member is in the deformed shape so that the mechanism is capable of performing the operational motion; and wherein after the transformation member is subject a transition temperature, the at least one transformation member changes from the deformed shape to the original shape and disengages a portion of the mechanism so that the mechanism is prevented from performing the operational motion.
Tissue securing device and method of use
This disclosure relates to a medical device. The medical device comprises a first and a second component. The first component comprises a first portion having a first handle part and a second portion having a grip. The second component is linked to the first component and is configured to be in communication with the first component to be actuated from an open to a closed position. The second component defines a third portion and a fourth portion, the third portion defining a second handle part and the fourth portion defining a second grip that is configured to grip a tissue in combination with the first grip portion of the first component. In certain embodiments, the first component or second component comprises a substantially straight member attached distally from the grip.
Electrically-insulative hinge for electrosurgical jaw assembly, bipolar forceps including same, and methods of jaw-assembly alignment using fastened electrically-insulative hinge
An end effector assembly suitable for use with a forceps includes opposing first and second jaw members pivotably mounted with respect to one another. The first jaw member includes one or more pivot holes defined therein configured to receive a portion of a pivot pin therein. The end effector assembly also includes an electrically-insulative hinge configured to electrically isolate the first and second jaw members from one another including one or more pivot-hole locators having an aperture defined therein. The electrically-insulative hinge is attached to the first jaw member such that the one or more pivot-hole locators align with the one or more pivot holes of the second jaw member.
Clip applicator
A surgical gripping/holding instrument having two instrument branches which are coupled pivotably with respect to one another. Each branch has a distal gripping/holding portion, a proximal instrument actuating portion, and an intermediate region which connects the distal and proximal portions preferably integrally, and having an instrument lock, of which the locking elements which can be brought into latching engagement with one another are arranged or formed on the instrument branches. The actuation of the instrument for opening and closing is functionally separated from actuation of the instrument for locking and unlocking the instrument by the positioning of the instrument lock in the intermediate region of the instrument. Therefore, each actuation can be carried out individually.
Manipulator for grasping tissue
A manipulator adapted to grasp and draw tissue comprises first and second arms having proximal ends and distal ends separated by a distance. First and second grasping surfaces each connected to and extending from respective distal ends of the first and second arms are biased toward each other by a respective spring force. When the first and second arms are actuated to reduce the distance, the manipulator is configured such that tissue arranged between the first and second grasping surfaces resist actuation of the first and second arms. The first and second arms are further actuatable to overcome the spring force of the first and second grasping surfaces so that the first and second grasping surfaces pivot at respective pivot points such that the distance between the distal ends of the first and second arms is reduced.
Instrument for selectively grabbing and cutting tissue
A surgical instrument configured for both grasping and cutting operations has a shaft with a push rod extending through it. An end effector on the shaft has a grasping jaw, a cutting jaw, and an intermediate jaw. The grasping jaw forms a grasping device with the intermediate jaw, and the cutting jaw forming a cutting device with the intermediate member. A segment of the shaft proximal to the end effector is axially rotatable between a first position, in which the push rod can advance through the segment to actuate the cutting device, and a second position in which the push rod can advance through the segment to actuate the grasping device.
Clamping forceps device
Clamping forceps device includes two clamps in pivotal connection to one another and each having an operator end for being operated by a health care provider. The device also includes an extension extending aft of the operator end of each clamp, the extension forming a space therebetween sized to form a disconnecting wedge mechanism for separating a tube from a patient tube connector. Each extension defines a ramped surface increasing in thickness moving from an extension tip towards the operator end.
METHODS AND DEVICES TO TREAT NASAL AIRWAYS
Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.
