A system comprises a surgical robot comprising a moveable robotic arm; a radiating applicator positioned at a distal end of the robotic arm, wherein the robotic arm is configured to move the radiating applicator to a desired operational position; and an energy source positioned on a distal portion of the robotic arm, in proximity to the radiating applicator, wherein the energy source is configured to provide RF or microwave energy to the radiating applicator for radiation by the radiating applicator.

The present invention discloses a cryoablation catheter, including: a main tube having a distal end, a proximal end, and at least one lumen; an expansion element, with which the distal end of the main tube is sleeved; a fluid delivery tube extending into an expansion element through the lumen of the main tube, an opening being provided at a distal end of the fluid delivery tube, and a cryogenic fluid being ejected out through the opening; a fluid recovery passage extending into the expansion element through the lumen of the main tube, a distal end of the fluid recovery passage being communicated with a recovery hole at the distal end of the main tube, and the cryogenic fluid flowing into the fluid recovery passage through the recovery hole; wherein the opening is linearly disposed in a length direction of the distal end of the main tube. With the cryoablation catheter according to the present invention, an ablation line may be formed on tissue to be ablated, and through single entirely-lined ablation or a few times of entirely lined continuous ablation, the one-time success rate of ablation is close to the success rate of a surgery.

A surgical instrument includes a housing, a shaft extending therefrom, an end effector assembly supported by the shaft, a movable handle, and a drive assembly. The drive assembly includes a translatable drive member for actuating the end effector assembly, and a torsion spring including first and second legs. The first leg is configured to translate through the housing in response to movement of the movable handle relative to the housing. The second leg is configured to translate through the housing in cooperation with the first leg to move the drive member longitudinally when a force acting on the drive member is less than a threshold force, and to remain in fixed position, thereby tensioning the torsion spring and retaining the drive member in fixed position when the force acting on the drive member is equal to or exceeds the threshold force.

A robotic platform system having a lower stage with a motorized cartesian carriage, an upper stage, and a needle insertion module that connects both stages together.

A device for treating skin includes two mechanical fingers for placement in contact with the skin. At least one of the fingers is moveable so as to change a separation distance between the fingers. The fingers are configured to concurrently conduct a generated radiofrequency electromagnetic signal to the skin so as to cause an electrical current to flow through the skin at a depth that corresponds to the separation distance.

An esophageal ablation system including a positioner, an elongated, flexible shaft extending from the positioner, and a microwave emitter assembly disposed near the distal end of the shaft. The emitter assembly includes one or more microwave antennae and a balloon for spacing the antennae relative to target tissue. The device may have an inner balloon for deploying the antenna. The systems, devices and methods disclosed are useful for treating Barrett's Esophagus, Esophageal Adenocarcinoma, and Squamous Cell Carcinoma.

The present invention relates to a treatment apparatus and a method of controlling the same. There are provided a treatment apparatus, including a handpiece, an RF generator generating RF energy, an insertion unit configured to advance and retract toward one direction of the handpiece, selectively inserted into a tissue, and electrically connected to the RF generator to transfer the RF energy to the inside of the tissue, and a substance storage unit receiving a therapeutic substance therein and detachably installed on one side of the handpiece to transfer the substance to the inside of the tissue by the advancing operation of the insertion unit and a method of controlling the same.

A surgical instrument for electrocautery is provided. The surgical instrument is a manually operable surgical instrument for electrocautery for use in laparoscopic surgery or various surgeries.

An electrosurgical instrument is disclosed including an end effector, a shaft assembly, and a link. The end effector includes a first jaw rotatable relative to a second jaw between an open position and a closed position. The shaft assembly includes an outer tube, a jaw tube disposed within the outer tube, an actuation band operably coupled to the jaw tube. The jaw tube is configured to move within the outer tube between a proximal end and a distal end. The link includes a first end and a second end. The first end of the link is pivotably coupled to the actuation band. The second end of the link is pivotably coupled to the first jaw. The jaw tube is configured to rotate the first jaw towards the closed position based on movement of the jaw tube towards the proximal end.

A medical device may include a handle, a sheath fixed relative to the handle, a longitudinal actuator movable relative to the handle, an end effector, a member extending proximally from the end effector through the sheath, with a portion of the member being fixed relative to the longitudinal actuator, and a rotation actuator. Movement of the rotation actuator may cause rotation of the member relative to the sheath, and movement of the longitudinal actuator may cause longitudinal movement of the member relative to the rotation actuator.
