A patch having at least first and second parts is applied to the skin to prepare the skin for a transdermal device to be applied subsequently. The second part defines the area of the skin in which the required preparation process should be carried out, either by removal of a third part to form an opening in the second part or by providing preparation means such as microneedles on the underside of the second part. The second part is then removed to leave the first part adhered to the skin, which can be used as a guide for correctly locating the transdermal device so that the working area of the device and the prepared area of the skin are in alignment.

An adapter assembly for a flexible circular stapler including a pusher assembly, a trocar assembly, a first drive assembly and a second drive assembly. The pusher assembly includes a pusher member, a puller member, and first and second pulley members. The trocar assembly includes a trocar member operably disposed relative to the pusher assembly. The first drive assembly includes a first cable for advancing and retracting the trocar member relative to the pusher assembly, and the second drive assembly includes a second cable for retracting the puller member to cause rotation of the first and second pulley members. Rotation of the first and second pulley members causes advancement of the pusher member.

An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.

A tool for a medical instrument includes a stationary component, a branch which is pivotable relative to the stationary component about a pivot axis, a transmission device for transmitting a force to the pivotable branch, and a coupling device for coupling the transmission device to the pivotable branch in such a way that a translation of the transmission device entails a pivoting movement of the pivotable branch about its pivot axis. The coupling device includes several coupling portions on the pivotable branch and several coupling portions on the transmission device. Each coupling portion on the pivotable branch is assigned to a corresponding coupling portion on the transmission device. The coupling portions are arranged and designed such that the coupling of pivotable branch and transmission device is effected, depending on the positions of pivotable branch and transmission device, by different pairs of corresponding coupling portions.

An instrument with a motor drive assembly detachable from a handle assembly and detachable from a gear assembly, where the gear assembly is inside the handle assembly and further the instrument comprising a standard telescope which is detachable from the instrument and a cutter/blade assembly detachable from an outer sheath. In an aspect, an instrument (1) includes a motor drive assembly (2) that is detachable from a handle assembly (3) and detachable from a gear assembly (5), wherein the gear assembly (5) is positioned inside the handle assembly (3), and wherein the motor drive assembly (2) is detachable for the purpose of being reused after cleaning or its replacement.

Described is a supporting base (1) for medical instruments (2), comprising a supporting layer (3) having a relative visible front surface (4) and a relative rear surface (5) opposite the visible surface (4); The supporting layer (3) also has a plurality of holes (6) extending from the front surface (4) towards the rear surface (5); More specifically, the supporting layer has a gripping portion (9) positioned on the rear surface (5) and irreversibly joined to the supporting layer (3) to form a single body with said supporting layer (3). The supporting base (1) has at least one opening (17) for inserting, in use, a medical instrument (2), positioned at each hole (6) and extending from the front surface (4) towards the rear surface (5) and through the gripping portion (9).

A surgical instrument has an ultrasonic blade that connects to a distal end of an ultrasonic waveguide. A clamp arm assembly is moveable from an opened position for receiving a tissue, toward a closed position for clamping the tissue. A clamp arm actuator connected to the clamp arm assembly directs the clamp arm assembly from the opened position toward the closed position. An outer sheath surrounds at least a portion of the ultrasonic waveguide. The outer sheath includes a cover removably received against a sheath body, and a sheath securement feature able to detachably couple the cover to the sheath body such that the cover can be detached from the sheath body for accessing the ultrasonic waveguide within the outer sheath.

An electrosurgical instrument with first and second branches pivotably arranged at a hinge is disclosed. The hinge is formed by a support pin at the second branch and a corresponding support cavity at the first branch. At one side adjacent to the hinge location at which the support pin extends into the support cavity, a knife guide cavity is provided in the second branch for a moveable guided support of a knife. Parallel to the pivot axis defined by the hinge, the knife guide cavity is arranged adjacent to an axial end of the support pin. The hinge or the hinge location formed by the hinge at which the support pin is arranged in the support cavity is only arranged on one side of the knife guide cavity viewed in a direction parallel to the pivot axis. The respective other side is free from hinge components.

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.

An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.
