A sheath assembly for use with an endoscope and an endoscope that includes the sheath assembly. The sheath assembly can include an elongate tubular sheath configured to thread onto a shaft of the endoscope. The sheath can include a pliable segment at a distal end of the sheath, and a tensile filament extends along a circumference of the pliable segment. The tensile filament can form a cinching loop at a distal end of the pliable segment. The sheath can be displaceable along the endoscope between a retracted position and an extended position. The pliable segment can extend distally beyond a distal end of the endoscope to form a chamber, and proximal displacement of the tensile filament tightens the cinching loop to convert the chamber from an open configuration to a closed configuration.

A hand piece for handling an optical fiber during a laser-surgical intervention comprises a handle body elongated along a main axis and having a through hole extending along the main axis. A guide tube having a tube lumen aligned and communicating with the through hole is attached to the handle body. A fixing device is provided in the handle body for fixing the optical fiber extending through the through hole and the tube lumen in direction of the main axis. The guide tube is made of a shaped memory alloy, which has a transition temperature between 50° C. and 120° C., and which has a straight base shape. Below the transition temperature, the guide tube is bendable by plastic deformation out of the straight base shape into a curved shape, and, when heated up above the transition temperature, the guide tube returns to its straight base shape.

A medical skin wrinkle reduction device using an RRSS laser irradiation method is proposed to reduce skin wrinkles and minimize tissue damage. The device includes: a main body having a mounting groove provided in an upper portion thereof, a tablet computer being attached to and detached from the mounting groove, and comprising signal transmission and reception parts exchanging signals with the tablet computer, and a microcomputer controlling an output of a laser beam; a handpiece comprising: a laser oscillation part generating the laser beam; an optical part emitting the laser beam as parallel light; a laser scanner controlling an irradiation position of the laser beam transmitted from the optical part; a laser pattern part having movement coordinate values set therein such that moving direction of the laser beam has a regular pattern; a tablet computer having functions of inputting data in a touch screen method and displaying a screen.

A surgical instrument includes a housing having a first handle and an elongated shaft extending therefrom. An end effector is disposed at a distal end of the elongated shaft and includes first and second jaw members, the first jaw member including a staple cartridge configured to house a series of staples therein. A second handle is operably coupled to the housing and is selectively moveable relative to the first handle to actuate the first and second jaw members between an open position and a closed position for grasping tissue. A first switch is activatable to supply energy to one of the jaw members. A stapler mode switch is actuatable between an unactuated position wherein movement of the second handle moves the jaws to the second position and an actuated position wherein movement of the second handle moves the jaws to the second position and drives the staples through tissue.

A medical punching/cauterizing device includes a handle having a body, a cap detachably coupled to a front portion of the body, a connection terminal coupled to the body and electrically connected to a power supply means, a conductor provided in the front portion of the body and having one end electrically connected to the connection terminal, and a guide wire provided on a front portion of the handle and having one end electrically connected to the conductor.

The invention provides a tip that permits therapeutic electromagnetic energy systems to deliver multiple beams of overlapping, partially overlapping, and non-overlapping electromagnetic energy in the treatment of tissue disorders and conditions. The tip finds use with laser systems, intense pulsed light systems, LED systems, radiofrequency systems, and microwave systems.

A method of assembling a jaw member of an electrosurgical forceps includes aligning in vertical registration an electrically conductive seal plate, an insulative spacer and a jaw support. The method further includes stacking the seal plate atop the insulative spacer and the jaw support such that a flange depending from the seal plate seats within a corresponding cavity defined within a flange depending from the insulative spacer which, in turn, seats within a cavity defined within the jaw support. The method further includes mechanically securing the seal plate, insulative spacer and jaw support to one another and securing a jaw housing to surround the jaw support, the insulative spacer and the seal plate.

Systems and methods for delivering energy to passageways in a patient, such as airways in the lung of a patient for treating asthma. One embodiment of a method for delivering energy to a passageway comprises positioning an access device in a lung airway of a patient and advancing an elongated body of a treatment device along the access device until an energy delivery unit at a distal portion of the elongated body projects from the access device. The method can further include expanding the energy delivery unit such that energy delivery elements contact a sidewall of the airway and activating an energy supply coupled to the treatment device such that energy is delivered to the sidewall of the airway. A single person physically operates both the access device and the treatment device while expanding the energy delivery unit and activating the energy supply.

A medical instrument comprising a device for activating or deactivating a function of the instrument. The device comprises first and second parts, which are each movable into an operative position relative to the other part to activate or deactivate a function of the instrument. A second control element for moving the second part into the operative position provides a control portion and comprises, for moving the first part into the operative position, a first control element which provides an additional control portion. The first control element can be moved in an opposite direction the direction from the second control element. Accordingly, the function is activated by moving a control element in a distal direction, and by moving another control element in a proximal direction. A deflection of force by one actuating element for actuating the first part or the second part in the opposite direction is not necessary.

A knife limit for a surgical instrument includes a housing having a shaft extending therefrom configured to support an end effector at a distal end thereof, the end effector including first and second jaw members. One or both of the jaw members including a knife channel defined therein and extending therealong to a distal portion thereof. A knife assembly is disposed within the housing and cooperates with a trigger to translate a knife within the knife channel to the distal portion of the jaw member upon actuation thereof. A knife limit button is disposed within the housing and is configured to limit the distal translation of the knife within the knife channel upon selective actuation thereof. The knife limit button is movable between a first position allowing full translation of the knife within the knife channel and a second position limiting distal translation of the knife within the knife channel.
