A surgical device includes a jaw assembly defining a first longitudinal axis and including a first jaw and a second jaw moveable relative to the first jaw; an elongated body defining a second longitudinal axis and coupled to a proximal end of the jaw assembly, wherein the jaw assembly is configured to articulate about an articulation axis transverse to the second longitudinal axis relative to the elongated body; and a handle assembly coupled to a proximal end of the elongated body and including at least one motor mechanically coupled to the jaw assembly and a control assembly including a first control button and a second control button, wherein actuation of the first control button moves the second jaw in approximation relative to the first jaw and actuating the second control button moves the second jaw away from the first jaw, and actuating the first and second control buttons moves the jaw assembly to a centered position in which the first and second longitudinal axes are substantially aligned, the handle assembly further includes an illumination member configured to output a light pattern indicative of a status of the surgical instrument.

Disclosed is a reusable surgical instrument (1) with an articulated end-effector (3), such as a dissector, scissor or grasper, to enhance a surgeon's performance during various surgical procedures. The longitudinal axis of the instrument is defined by a shaft (2), comprising an internal structural element (2″) covered by an external tube (2′), which may be inserted through a surgical incision into the body of a patient, optionally through a trocar. The articulated end-effector (3) is mounted on the distal extremity of the shaft's internal structural element and comprises a plurality of links interconnected by a plurality of joints, whose movements are remotely actuated by the surgeon's hands. This remote actuation is accomplished via mechanical transmission (5, 6, 7), mainly composed of flexible elements, which are able to deliver motion from a set of actuation elements, placed at a proximal extremity of the shaft (2), to the instrument's articulated end-effector (3). The external tube (2′) can be easily and individually detached from the shaft (2) after each procedure, so that the instrument (1) can be more effectively cleaned and sterilized.

A surgical instrument includes an outer housing shell defining a cavity, the outer housing shell defining an upper outer housing half and a lower outer housing half, wherein the upper outer housing half defines a longitudinal axis and an instrument module selectively insertable into the cavity of the outer housing shell. The instrument module includes an inner housing shell, at least one motor disposed within the inner housing shell, a control board being in electrical communication with the at least one motor and an energy source being in electrical communication with the at least one motor and the control board. The instrument module is inserted into the cavity of the outer housing shell in such a manner that the operative axis of the at least one motor is substantially parallel to the longitudinal axis of the upper outer housing half.

The present disclosure relates to a surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member configured to releasably receive a firing assembly and a single use loading unit. A lockout structure prevents insertion of the single use loading unit into the channel member after the firing assembly is mounted to the cartridge receiving half-section. Alternatively, the lockout structure prevents full insertion of the firing assembly into the cartridge receiving half-section, if the single use loading unit is not engaged with the firing assembly.

A laryngopharyngoscope retractor system including: a plurality of components including: a base frame with a coupling region and a spatula holder that is adjustable in terms of position and orientation by way of adjusting screws; a spatula that is releasably fastenable in the spatula holder; two cheek holder adapters that are releasably fastenable to the base frame; and two cheek holders, each of which is releasably fastenable to a respective cheek holder adapter, wherein one or more of the base frame, the spatula holder, the spatula, the cheek holder adapter and the cheek holder, in the respective regions provided for the releasable connection to another one of the plurality of components have a visible unique code that corresponds to the corresponding regions on the other of the plurality of components.

The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

Disclosed is a breath sampling device comprising a buffer tube, sensor module and breath sampling port. The buffer tube has a proximal end into which a user exhales and a distal end opposite the proximal end, the sensor module is at the distal end and used for measuring parameters of a breath exhaled by the user into the buffer tube, and the breath sampling port is disposed between the proximal end and distal end. The used exhales into the distal end and a portion of the exhaled breath can be diverted into the sampling port substantially without contacting the sensor module.

A surgical method for operating a trocar defining an access port for a surgical instrument, using a holding arm and a number of drives. The method includes: inserting the trocar through an abdominal wall of the patient body; operating at least one drive to move the surgical instrument in the patient body; operating at least one drives to actuate an effector; and moving the holding arm to generate a pivoting movement of the trocar and surgical instrument about a pivot point defined by the abdominal wall of the patient body. The trocar is freely pivotable relative to the holding device, and the pivoting movement is caused by contact between the trocar and the abdominal wall of the patient body or an elastic membrane located on the abdominal wall of the patient body.

A surgical device is provided. The surgical device includes a jaw assembly defining a first longitudinal axis and including a first jaw and a second jaw moveable relative to the first jaw; an elongated body defining a second longitudinal axis and coupled to a proximal end of the jaw assembly, wherein the jaw assembly is configured to articulate about an articulation axis transverse to the second longitudinal axis relative to the elongated body; and a handle assembly coupled to a proximal end of the elongated body and including at least one motor mechanically coupled to the jaw assembly and a control assembly including a first control button and a second control button, wherein actuation of the first control button moves the second jaw in approximation relative to the first jaw and actuating the second control button moves the second jaw away from the first jaw, and actuating the first and second control buttons moves the jaw assembly to a centered position in which the first and second longitudinal axes are substantially aligned, the handle assembly further includes an illumination member configured to output a light pattern indicative of a status of the surgical instrument.

The present disclosure provides a clamp for attaching or detaching a medical shaver, in which the clamp is provided for attaching and detaching a suction tube (30) detachably coupled to and rotated together with a shaft (20) rotated in a shaver body, and includes: a body; a detachment groove (120) formed in a direction perpendicular to a longitudinal direction on a front surface of the body; a detachment slit (125) formed in a direction perpendicular to the longitudinal direction on an upper surface of the body to communicate with the detachment groove; and an attachment groove (145) formed along the longitudinal direction at a center of a right side surface of the body.
