A system for correcting a lateral curvature of a spine that can include a plurality of screws configured to be implanted in a plurality of vertebrae, and a plurality of extensions configured to be removably coupled with the plurality of screws. Some embodiments of the plurality of extensions can be curved, bent, angled, and/or offset along at least a portion thereof and can be removably coupled with a screw head of each of the plurality of screws. The system can include a connecting element or rod that is configured to be coupled with the plurality of screw heads. Some embodiments of the system can be configured such that the rod can be guided along the plurality of extensions from the proximal toward the distal end portions of the extensions and into engagement with the plurality of screws to cause the plurality of vertebrae to move laterally.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to: detect an intent of a user of a computer-assisted surgical system to use a robotic instrument attached to the computer-assisted surgical system to interact with a target object while the target object is located in a surgical space; determine a pose of the target object in the surgical space; and perform, based on the detected intent of the user to interact with the target object and the determined pose of the target object in the surgical space, an operation with respect to the target object.

A laser irradiation device for performing treatment on human skin includes a casing that includes a grip part and a barrel part; a laser oscillator that is accommodated in the casing and configured to generate a laser beam to be irradiated through the barrel part; a contact sensor unit that includes electrodes exposed at the end of the barrel part and a contact sensing unit configured to sense an electric current flowing through the electrodes; and a skin treatment unit that is detachably connected to the barrel part and is operated based on electric signals transmitted through the electrodes of the contact sensor unit.

The disclosure provides a diagnosis and treatment integrated soft medical robot for gastrointestinal endoscopy, including a robot body, a camera, illumination devices, a flexible dielectric elastomer actuator, air cylinders, linear motors, a controller and external hoses. Wherein the robot body is a multichannel hose, and includes a central channel and circumferential channels, the central channel is configured to accommodate conducting wires and signal wires, the circumferential channels include at least three microfluid channels. The front end of each microfluid channels is a sealed end, a rear end of each of the microfluid channels is an open end. The open end of each microfluid channels communicates with an end opening of a flow channel of one air cylinder. The linear motors control fluid pressures in the microfluid channels by driving piston rods of the air cylinders so that the robot body steers through being driven by fluid. The camera performs real-time image acquisition. The controller controls the flexible dielectric elastomer actuator to capture a target. The disclosure realizes the real-time image acquisition on a digestive tract, particularly a lesion, and can integrally and fast complete diagnosis and treatment.

A surgical system includes a housing, an ultrasonic transducer supported by the housing, an end effector assembly distally-spaced from the housing, a clamp lever, and a sensor. The end effector assembly includes an ultrasonic blade operably coupled to the ultrasonic transducer for receiving ultrasonic energy produced by the ultrasonic transducer, and a jaw member pivotable relative to the blade from an open position towards a clamping position for clamping tissue between the jaw member and the blade and imparting a clamping force to the clamped tissue. The clamp lever is operably coupled to the housing and the jaw member such that actuation of the clamp lever relative to the housing pivots the jaw member towards the blade. The sensor is configured to sense whether the clamp lever is sufficiently actuated so as to impart the clamping force to the clamped tissue.

A powered surgical device includes a power source and a motor coupled to the power source. The device may also include a transmission assembly movable by the motor. The device may also include a sensor configured to monitor operation of the transmission assembly and output sensor data. The device may also include a controller configured to: determine position of the transmission assembly and operate the motor based on the position of the transmission assembly and an interruption in the sensor data.

Systems, methods, and devices are disclosed for surgical instruments, systems, and methods for detecting skiving of a surgical instrument, such as an instrument used during a robotic or robot-assisted surgery. The embodiments disclosed herein may include one or more sensors adjacent to, coupled to, disposed on, or embedded into an instrument in order to measure deflection thereof during use that may indicate skiving of the instrument. A variety of sensors may be utilized, including strain gauges, resistance-based sensors, fiber optic cables, laser distance measurement units, ultrasonic distance measurement units, optical cable measurement units, etc. In some embodiments, multiple such sensors may be included in an instrument in order to measure magnitude and/or direction of deflection.

This disclosure relates to diagnostic devices for diagnosing lymphedema. The diagnostic devices may include an array of sensors, which can at least include a durometer, temperature sensor, and dielectric sensor, to measure parameters of tissue. The measurements may be used to generate a tissue health score to diagnose lymphedema and monitor tissue heath.

Described here are methods and apparatuses for tracking a clot material within a lumen of a suction catheter. For example, an apparatus as described herein may include a flexible elongate body having a suction lumen, a first pair of electrodes within the suction lumen, a second pair of electrodes proximal to the first pair of electrodes, and a controller configured to track a clot material within the suction lumen based on signals from the first pair of electrodes and the second pair of electrodes.
