A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

An ultrasonic surgical system includes an ultrasonic generator configured to provide an ultrasonic drive signal, and an ultrasonic transducer electrically coupled to the ultrasonic generator to receive the ultrasonic drive signal therefrom and configured, in response to the received ultrasonic drive signal, to produce a mechanical motion. The ultrasonic surgical system further includes a sensor configured to sense a frequency and a magnitude of the mechanical motion, and a controller configured to receive a target mechanical motion to be produced by the ultrasonic transducer and control the ultrasonic drive signal so that a frequency of the ultrasonic drive signal falls within a frequency range around a resonant frequency of the ultrasonic transducer, the frequency range corresponding to the target mechanical motion produced by the ultrasonic transducer.

A surgical tool may move a saw blade in a sagittal plane. The saw blade has a distal blade end with teeth. The surgical tool comprises a handpiece body and a carrier operatively attached to the handpiece body. The carrier is configured for oscillating movement about a pivot axis. A retainer is operatively attached to the carrier for concurrent movement and releasably secures the saw blade in the sagittal plane relative to the handpiece body. An actuator is coupled to the handpiece body to selectively oscillate the carrier relative to the handpiece body such that the retainer and the saw blade pivot back and forth about the pivot axis within the sagittal plane. An ultrasonic transducer is operatively attached to the handpiece body to selectively generate ultrasonic energy to resonate the saw blade such that the teeth at the distal blade end reciprocate proximally and distally within the sagittal plane.

A fractional handpiece and systems thereof for skin treatment include a passively Q-switched laser assembly operatively connected to a pump laser source to receive a pump laser beam having a first wavelength and a beam splitting assembly operable to split a solid beam emitted by the passively Q-switched laser assembly and form an array of micro-beams across a segment of skin. The passively Q-switched laser assembly generates a high power sub-nanosecond pulsed laser beam having a second wavelength.

Provided herein are expandable devices, rail systems, and motorized devices. In one embodiment, an expandable device comprises an expandable sac having a tool housed therein. The expandable device is optionally configured for operation while inside a body cavity. The expandable device optionally comprises at least one rail in the sac, and at least one railed device coupled to the rail for movement there on. Movement of the railed device on the rail is provided by, for example, a motor such as an electromagnetic motor or an inch-worm type motor. Expandable devices can be used, for example, to perform minimally invasive medical procedures requiring access to a body cavity. Expandable devices can also be used, for example, to provide safe and stable transport of instruments to the body cavity.

A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer circuit coupled to the control circuit. The timer circuit is configured to measure elapsed time and to to receive, from the position sensor, a position of the displacement member in a current zone during a set time interval, measure displacement of the displacement member at a set time at the end of the set time interval, wherein the measured displacement is defined as the distance traveled by the displacement member during the set time interval at a set command velocity for the current zone, and set a command velocity of the displacement member for a subsequent zone based on the measured displacement of the displacement member within the current zone.

A surgical instrument comprising a first jaw, a moveable second jaw, and one or more mounting brackets that retain said second jaw to said first jaw is disclosed.

An adaptive flow rate control system for a surgical device, whereby the control system includes one or more nonintrusive sensors configured to be positioned on an aspiration conduit extending downstream from a handheld surgical device to measure flow and reduce clogging within the aspiration conduit is disclosed. The nonintrusive sensor may provide data to a controller of a handheld surgical device system to enable it to control operation of the handheld surgical device based at least in part on the data from the adaptive flow rate control system to prevent clogging of the aspiration system. The adaptive flow rate control system may also include a clog tracking module and a clog prediction module. The adaptive flow rate control system may include a wireless communication system configured to communicate with other components of a surgical device system and may communicate with a external network and resources on the internet.

A medical apparatus can include an instrument comprising a shaft and a jaw assembly coupled to an end of the shaft; an image capture device; and a controller operably coupled to the image capture device to receive image data from the image capture device. The image data is from images of material gripped between jaw members of the jaw assembly and captured by the image capture device, with the controller programmed to process the received image data using at least one of optical flow and digital image correlation. A medical apparatus can include an instrument comprising a shaft, and a jaw assembly coupled to an end of the shaft, the jaw assembly comprising a pair of jaw members having opposing surfaces configured to grasp material between the opposing surfaces, wherein at least a portion of the opposing surface of a first jaw member of the pair of jaw members is transparent.

A passive end effector of a surgical system includes a base connected to a rotational disk, and a saw attachment connected to the rotational disk. The base is attached to an end effector coupler of a robot arm positioned by a surgical robot, and includes a base arm extending away from the end effector coupler. The rotational disk is rotatably connected to the base arm and rotates about a first location on the rotational disk relative to the base arm. The saw attachment is rotatably connected to the rotational disk and rotates about a second location on the rotational disk. The first location on the rotational disk is spaced apart from the second location on the rotational disk. The saw attachment is configured to connect to a surgical saw including a saw blade configured to oscillate for cutting. The saw attachment rotates about the rotational disk and the rotational disk rotates about the base arm to constrain cutting of the saw blade to a range of movement along arcuate paths within a cutting plane.
