An ultrasonic transducer and generator (TAG) assembly of a surgical instrument includes generator components and transducer components. The generator components are disposed within a first cavity cooperatively defined by a body portion and a cover. The generator components are covered in a thermally insulative material. The transducer components are disposed within a second cavity cooperatively defined by a proximal housing and a spinner housing.

A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

Bipolar surgical instrument

An enclosure configured to hermetically seal electronics of a surgical instrument therein includes a first casing component defining a first weld deck about a perimeter thereof, a second casing component defining a second weld deck about a perimeter thereof, and an energy director extending from the first weld deck and configured to facilitate ultrasonic welding of the first and second weld decks of the first and second casing components, respectively, with one another to establish a weld seam hermetically sealing the first and second casing components. The first weld deck lies in multiple planes.

Enclosure for electronics of a surgical instrument

A surgical instrument includes a housing, an end effector including a clamp jaw, a drive member extending distally from the housing, and a clamp lever pivotably coupled to the housing. The drive member is operably coupled to the clamp jaw such that translation of the drive member pivots the clamp jaw from an open position towards a clamping position. The clamp lever is operably coupled to the drive member via a rigid slider. The clamp jaw is configured to provide a jaw force to clamped tissue, measured at about 0.192 inches from a distal end of the clamp jaw, of from about 1 lbf to about 8 lbf in response to a full actuation of the clamp lever.

A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly has electrodes releasably coupleable to the jaw members and adapted to connect to a source of electrosurgical energy to allow selective conduction of electrosurgical energy through tissue held therebetween to effect a tissue seal. An electrically conductive cutting element is disposed on at least one of the electrodes and is adapted to connect to the source of electrosurgical energy to allow selective conduction of electrosurgical energy through tissue held between the electrodes to effect a tissue cut.

A method of assembling an electrosurgical instrument includes coupling first and second shafts to each other about a pivot. Each of the shafts has an interior side facing the other shaft and an exterior side opposite the interior side. The method also includes disposing a knife blade at least partially through a passageway defined through the pivot from the exterior side of the first shaft and coupling a knife actuation mechanism to the first shaft from the exterior side of the first shaft. The knife actuation mechanism is configured to move the knife blade through the passageway.

Method of assembling an electrosurgical instrument

A system includes an energy source and a surgical device. The energy source has a receptacle configured to delivery energy to the surgical device through a receptacle. The surgical device is configured to deliver the energy to tissue. The surgical device includes a plug selectively engagable to the receptacle to couple the surgical device to the energy source. The plug includes a prong configured to mechanically transition from a condition permitting engagement of the plug and the receptacle to another condition inhibiting engagement of the plug with the receptacle upon reaching a predetermined usage threshold.

Limited-use surgical devices

A jaw member includes an insulative member and a substrate. The substrate is formed as a single, integral component that has first and second side portions interconnected by a connector portion. The connector portion has first and second side portions that are interconnected by an arc-shaped portion. The connector portion is configured to be removed before use of the jaw member such that the first and second portions are electrically insulated from one another.

Disposable housing for open vessel sealer with mechanical cutter

An electrosurgical forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The forceps also includes a switch assembly that includes a supporting member, a flexible membrane circuit having snap dome switch contacts operably fixed thereto, and ergonomically-contoured keytops. The switch assembly provides at least one monopolar activation switch, and a bipolar activation switch. The forceps also include a drive mechanism which causes the jaw members to move relative to one another for manipulating tissue. A monopolar safety switch is incorporated into the switch assembly which cooperates with the drive mechanism to inhibit the monopolar activation switch when the jaw members are in an open position.

Switch assembly for electrosurgical instrument

A method of manufacturing an end effector assembly including first and second energizable portions configured to supply energy to tissue is provided. The method includes forming a substrate including first and second portions interconnected by a connector portion. The substrate is formed as a single integrated component. The method further includes engaging the substrate with an insulative member, and removing the connector portion of the substrate to electrically insulate the first and second portions from one another.

A medical device including one or more components positioned to contact contaminants during use of the medical device. The one or more components including one or more limited-use portions transitionable upon use from an initial state, wherein the limited-use portion(s) exhibits a clean appearance, to a used state, wherein the limited-use portion(s) exhibits a contaminated appearance that visually indicates to a user that the at least one component is not further usable.
