In a liquid ejection control device, an ejection tube section type acquisition unit discriminates an ejection tube section type of an ejection tube section mounted in a main body section, and acquires a fitted correspondence relationship fitting the discriminated ejection tube section type. A voltage amplitude setting unit sets a voltage amplitude of a drive voltage waveform so as to cause momentum to meet a momentum instruction value input by using a momentum dial based on a rising index value related to rising of the drive voltage waveform and a repetitive frequency instruction value input by using a repetitive frequency dial with reference to the fitted correspondence relationship.

A surgical instrument includes a handle assembly and an adapter assembly. The handle assembly includes a handle housing and a processor disposed within the handle housing. The adapter assembly includes a knob housing, an elongate body, a plurality of electrical components, and a flex circuit. The knob housing is configured to be connected to the handle housing. The elongate body extends distally from the knob housing and has a distal end configured to be coupled to an end effector. The electrical components are disposed within the elongate body. The flex circuit has a proximal end configured to be electrically connected to the processor, and a distal end configured to be electrically connected to the electrical components.

The present disclosure provides for a surgical device. The surgical device includes a jaw assembly and a camera assembly coupled to the jaw assembly. The camera assembly includes a camera housing defining an interior space having at least one opening on a side thereof, first and second support arms pivotally coupled within the camera housing and deployable therefrom, and a camera body coupled to the first and second support arms and moveable between a first position, in which the camera body is positioned within the interior space of the camera housing, and a second position, in which the camera body extends from the at least one opening of the camera assembly.

An adapter assembly for connecting an end effector to an actuation assembly includes a base member defining a plurality of notches spaced at least partially about a circumference of the base member, a handle supported on the base member and rotatable about a longitudinal axis of the base member, and a latch mechanism supported on the handle assembly and selectively engageable with the base member. The latch mechanism includes a button member and a locking member. The button member is movable between a first position in which the locking member is received within one of the plurality of notches to lock the handle relative to the base member, and a second position in which the locking member is spaced from the plurality of notches to unlock the handle relative to the base member.

There is a need for a minimally invasive surgical treatment method for periodontitis for the removal of deep pockets, elimination of disease, creation of reattachment of the gingiva to the tooth surface and true regeneration of the attachment apparatus (new cementum, new periodontal ligament, and new alveolar bone) on a previously diseased root surface. The PerioLase® MVP-7™ including eGUI or another device capable of laser dosimetry, such as an original MVP-7™ type laser without the eGUI, achieves this with the LANAP protocol (laser-assisted new attachment procedure) and the LENAP protocol (laser excisional new attachment procedure).

A surgical instrument including a housing, an endoscopic portion, a shaft portion and an end effector is disclosed. The endoscopic portion extends distally from the housing and defines a longitudinal axis. The shaft portion is selectively connectable to a distal end of the endoscopic portion. The end effector is selectively connectable to a distal end of the shaft portion.

A method of treating tissue includes positioning a probe in proximity to tissue, reducing a temperature of the tissue such that a temperature of a portion of the tissue that is closer to the probe is less than a temperature of a portion of the tissue that is farther from the probe, and raising a temperature of the tissue such that the temperature of the portion of the tissue that is closer to the probe increases at a faster rate than the temperature of the portion of the tissue farther from the probe.

A surgical system comprising an elongate shaft and an end effector is disclosed herein. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples removably stored therein, wherein the first jaw is movable relative to the second jaw. The surgical system further comprises a first rotatable drive system configured to close the first jaw and a second rotatable drive system. The second rotatable drive system comprises a drive screw, a drive member movable between a proximal position and a distal position during a staple firing stroke, and a sled configured to eject the staples from the staple cartridge during the staple firing stroke. The sled is not pulled proximally by the drive member when the drive member is retracted. The end effector, the drive screw, and the sled comprise a replaceable assembly.

An electromechanical surgical system is disclosed including a hand-held surgical instrument, an end effector configured to perform at least one function, and a shaft assembly arranged for selectively interconnecting the end effector and the surgical instrument. The shaft assembly includes a linkage having a proximal housing and a distal housing at least partially received within the proximal housing. The distal housing is rotatable relative to the proximal housing and configured to selectively interconnect the end effector to the shaft assembly. The shaft assembly further includes a wire extending through the linkage having a central portion disposed within an annular groove defined between the proximal and distal housings. The central portion of the wire is annularly wound within the annular groove to define a coil. The coil is configured to at least one of radially expand and contract upon rotation of the distal housing relative to the proximal housing.

A resecting probe includes a shaft assembly having an outer sleeve and an inner sleeve. The outer sleeve has an axial bore and an outer window in a distal side thereof, and the inner sleeve has an axial extraction channel and inner window in a distal side thereof. The inner sleeve is rotationally disposed in the axial bore of the outer sleeve to allow the inner sleeve window to be rotated in and out of alignment with the outer sleeve window, and the shaft assembly forms a flow aperture in a distal portion when the inner cutting window and the outer cutting window are out of alignment. An electrode is carried on the inner sleeve, and a motor drive is coupled to rotate the inner sleeve relative to the outer sleeve. A controller is coupled to the motor drive and controls rotation of the inner sleeve.
