Abstract:
A forceps includes an end effector assembly having first and second jaw members. Each of the jaw members includes a proximal flange extending therefrom. Each of the proximal flanges defines a bifurcated configuration having first and second spaced-apart flange components. The first flange component of the first jaw member is configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling. The first flange component of the second jaw member is configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling different from the first protrusion-aperture coupling. One or both of the jaw members is pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween.
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 method for manufacturing a pair of jaw members configured for use with an electrosurgical forceps is provided. One or more pairs of seal plates are stamped from a sheet metal. The seal plates are positioned into respective mold cavities. An insulative substrate is introduced into the respective mold cavities. The insulative substrate is allowed to harden in the respective mold cavities to form respective jaw housings with seal plates secured thereto. The jaw housings are removed from the respective mold cavities to form a pair of jaw members.
Abstract:
A method of manufacturing a shaft of a surgical instrument including forming a proximal segment of the shaft to include one or more features for operably engaging the shaft to a first component of the surgical instrument, forming a distal segment of the shaft to include one or more features for operably engaging the shaft to a second component of the surgical instrument and forming an intermediate segment of the shaft. The proximal segment is welded to a proximal end of the intermediate segment; and the distal segment is welded to a distal end of the intermediate segment. The proximal and distal segments are welded to the intermediate segment such that the one or more features thereof are aligned in a pre-determined orientation relative to one another.
Abstract:
A surgical instrument includes an end effector assembly having first and second jaw members moveable relative to one another between a spaced-apart position and an approximated position for grasping tissue therebetween. In the approximated position, the jaw members cooperate to define a cavity that is configured to house tissue grasped between the jaw members. An injectable material configured for injection into the cavity defined by the jaw members is also provided. The injectable material is configured to substantially surround tissue housed within the cavity. The injectable material is transitionable from a first state, facilitating injection of the injectable material into the cavity, to a second state, wherein the injectable material forms about tissue housed within the cavity to occlude tissue.
Abstract:
A surgical instrument includes a housing supporting first and second actuators thereon, and an elongated shaft extending distally from the housing. First and second drive members extend through the elongated shaft to operatively couple respective actuators to respective jaw members such that independent manipulation of one of the actuators may induce pivotal movement of an individual jaw member. A locking member is operatively associated with the first and second drive members, and is selectively movable between locked and unlocked positions. When the locking member is in the locked position, the first and second drive members are coupled to one another and move concurrently to drive the jaw members in a bilateral manner. When the locking member is in the unlocked position, the drive members are decoupled from one another and move independently to permit operation of the instrument in a unilateral manner.
Abstract:
An endoscopic forceps is provided and includes a housing having a shaft that extends therefrom. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members that are pivotably coupled to one another and movable relative to one another. The first and second jaw members are disposed in a first configuration, wherein the first and second jaw members are disposed in spaced relation relative to one another, to a second configuration, wherein the first and second jaw members cooperate to grasp tissue therebetween. A magnetic actuation mechanism is operably coupled to one or both of the first and second jaw members and configured to generate opposing magnetic fields on each of the first jaw and second jaw members to actuate the first and second jaw members between the first and second configurations.
Abstract:
A bipolar forceps is provided. The bipolar forceps includes a housing having a shaft including an electrically conductive distal end. A drive assembly is operable to reciprocate an actuation tube within the shaft. A portion of the actuation tube is electrically conductive. An end effector assembly operatively connects to the shaft and includes a pair of first and second jaw members biased in an open configuration. The first and second jaw members are pivotable about a living hinge. Distal reciprocation of the actuation tube causes each of the jaw members towards one another about the living hinge. One of the jaw members is in electrical communication with the distal end of the shaft and the other jaw member is in selective electrical communication with a distal end of the actuation tube such that when the jaw members are in a closed configuration a closed loop electrical circuit is formed.
Abstract:
An IRD is provided with expanded self-test capabilities, both hardware and software, that will provide standardized and more precise diagnostics. The IRD runs a sequence of tests to determine the fitness of the IRD and the health of the ODU. As the tests are completed, the results are displayed on-screen and written to a report. If a test fails, the appropriate remedial action such as “reset to factory default settings”, “service call” or “replace IRD, access card, modem, ODU” is also written to the report. The IRD appends the test report to a header message and forwards it to the service provider. The satellite service provider archives the report, modifies the header message to provide customer contact information and the responsible dealer, and forwards the file to the service dealer. To improve service and accountability, the dealer may send an acknowledgement back to the service provider and customer.
Abstract:
A method and apparatus for encoding and decoding data is described. The present invention includes a method and apparatus for generating transformed signals in response to input data. In one embodiment, the transformed signals are generated using a reversible wavelet transform. The present invention also includes a method and apparatus for compressing the transformed signals into data representing a losslessly compressed version of the input data. In one embodiment, the present invention decomposes the input data using a non-minimal length reversible filter. The decomposition may be performed using multiple one-dimension filters.
