Bipolar electrosurgical features for targeted hemostasis
An apparatus is configured to operate on tissue. The apparatus includes an end effector with an upper jaw and a lower jaw. The upper jaw is configured to pivot relative to the lower jaw. The apparatus also includes an electrode cap coupled to either the upper or lower jaw. The electrode cap includes a first electrode surface configured at a first polarity and a second electrode surface configured at a second polarity. The second polarity is opposite to the first polarity. The electrode cap is configured to be applied to tissue such that the electrode cap is operable to deliver bipolar RF energy to the tissue. The electrode cap may be used to selectively weld bleeding tissue in a localized fashion, without having to place the tissue between the jaws, and without having to use an instrument separate from the jaws.
MEDICAL DEVICE INTERFACE
A medical device comprising: (a) an interface including: (i) a first portion including: (1) a body portion connected to N a handle of a scalpel; and (2) a connection adapter; (ii) a second portion; wherein the connection adapter includes an interface portion that is a channel and the second portion includes an interface portion that is a tab that extends into the channel so that the first portion is connected to the second portion or wherein the second portion includes an interface portion that is a channel and the connection adapter includes an interface portion that is a tab that extends into the channel so that the first portion is connected to the second portion.
Ablation overtube
An energy delivery system and a method of delivering energy to a tissue are provided. The energy delivery system includes an overtube. The overtube includes a body having a proximal portion, a distal portion and a lumen extending at least partially therethrough. The proximal portion is adapted to be positioned over a distal portion of an endoscope. The body also includes a first plurality of openings formed in the body and connected to the lumen and an electrode operably connected to the body and extending over at least a portion of a surface of the body. The lumen is operably connectable to a vacuum source and the electrode is operably connectable to a power source.
CUT AND SEAL INSTRUMENT
A surgical system including a cartridge having a first tissue sealing electrode and a surgical instrument including a first jaw and a second jaw, wherein the first jaw comprises a second tissue sealing electrode facing the second jaw, and wherein the second jaw is configured to removably receive the cartridge in a position where the first tissue sealing electrode is opposite the second tissue sealing electrode. The surgical system further includes a cut and seal controller, wherein the cut and seal controller automatically generates a command to the surgical instrument to reduce a clamping force between the first and the second jaws after sensing that tissue sealing is complete.
Surgical forceps including reposable end effector assemblies
A surgical forceps includes a housing having a movable handle coupled thereto and movable between an initial position and a compressed position. A drive bar is operably coupled to the movable handle such that movement of the movable handle between the initial and compressed positions effects longitudinal translation of the drive bar. The drive bar further includes a coupling member disposed at a distal end thereof. An end effector assembly includes first and second jaw members movable between spaced-apart and approximated positions. Each jaw member defines a cam slot. A cam pin is slidably disposed within the cam slot of each of the jaw members. The coupling member is configured to releasably engage the cam pin such that movement of the movable handle between the initial position and the compressed position effects movement of the jaw members between the spaced-apart position and the approximated position.
Limited reuse ablation needles and ablation devices for use therewith
A surgical instrument includes a reusable component and a limited-use component releasably engagable with the reusable component. The limited-use component is configured for one or more uses and includes a clocking mechanism configured to count each engagement of the reusable component and the limited-use component to one another. The clocking mechanism is incrementally transitionable upon each successive count from one or more uses state, wherein the clocking mechanism permits both mechanical engagement and electrical coupling of the reusable component and the limited-use component to one another, to a spent state, wherein the clocking mechanism inhibits both mechanical engagement and electrical coupling of the limited-use component and the reusable component to one another.
HIGH VOLTAGE CONNECTORS AND ELECTRODES FOR PULSE GENERATORS
A handheld, therapeutic electrode and connector that are compatible with high voltages from a pulse generator are disclosed. The electrode includes therapeutic terminals on a tip configured to deliver high voltage pulses safely to a patient. The electrode includes sleeves, bosses, wiring channels, and other features that maximize a minimum clearance distance (across non-conductive surfaces) and air clearance between conductive connectors themselves or the connectors and a user, thus preventing dangerous arcing. Internal surfaces and seams are taken into account. The connector and its mating outlet can include similar features to maximize clearance distance. Skirts, skirt holes, and finger stops are also employed, and they can be on either the connector or outlet, or the tip or handle of the electrode.
ELECTRODE CATHETER WITH CORRUGATED SUPPORT STRUCTURE
An effector having a support frame with one or more corrugated struts is presented herein. Corrugation of a strut increases lateral stiffness of the strut and decreases axial bending stiffness of the strut compared to a linear, non-corrugated strut of similar thickness. Geometry of corrugations can be selected to provide conformal contact of the end effector to tissue while maintaining a desired spatial relationship between electrodes of the end effector. The geometry that can be selected can include amplitude of undulations, wavelength of undulations, and placement of a particular geometry within the end effector.
HAND-HELD ELECTROSURGICAL INSTRUMENT, INSULATING INSERT AND ELECTRODE SUPPORT FOR HAND-HELD ELECTROSURGICAL INSTRUMENT
An insulation insert, an electrode carrier and an electrosurgical handheld instrument which can be used particularly efficiently and which is producible particularly cost-effectively. This is achieved by virtue of the insulation insert having a tube-like embodiment and being detachably couplable by way of a proximal end region to a distal end of a tube-like shaft of the handheld device and a central passage serving to accommodate an inner shaft of the handheld device. Two drilled holes for accommodating a respective electrode carrier tube of an electrode carrier are arranged opposite one another in a wall of the insulation insert and parallel to the central passage.
METHOD AND KIT FOR TREATMENT OF TISSUE
Methods for creating a desired tissue effect. An RF electrode is provided that includes a conductive portion. The RF electrode is coupled to a fluid delivery member that delivers a cooling fluidic medium to a back surface of the RF electrode. A dielectric is positioned on a skin surface. The RF electrode is coupled with the dielectric. RF energy is delivered from the RF electrode and the dielectric to the skin surface.
