An energy treatment system and a output control method thereof according to embodiments of the present invention perform treatment by energy supply in which ultrasonic energy and high frequency energy are combined, stop or suppress discharge by reducing the output of high frequency energy within a set period when a state in which discharge is likely to occur during treatment is detected, and change the output of ultrasonic energy. In addition, in order for a user to continue treatment without feeling uncomfortable and to ensure incision performance, each output is controlled so that the set period is as short as possible or is supplemented, and also, the set period expires, and control is performed so as to reduce the possibility of discharge even at the time of returning.

A power delivery approach for delivering power to an electrosurgical vessel sealer when the jaws of the sealer surround tissue to be desiccated. Power delivery commences at a starting point that is at least 40 Joules and then decreases over a first predetermined period of time to a predetermined minimum power level to provide approximately 15 Joules in total. When the predetermined minimum power level is reached, power is then continuously increased over a second predetermined period of time to fully desiccate the tissue. Power delivery is terminated prior to over-desiccation of the tissue.

A generator, ultrasonic device, and method for controlling a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature.

According to some embodiments, a medical instrument (for example, an ablation device) comprises an elongate body having a proximal end and a distal end, an energy delivery member positioned at the distal end of the elongate body, a first plurality of temperature-measurement devices carried by or positioned within the energy delivery member, the first plurality of temperature-measurement devices being thermally insulated from the energy delivery member, and a second plurality of temperature-measurement devices positioned proximal to a proximal end of the energy delivery member, the second plurality of temperature-measurement devices being thermally insulated from the energy delivery member.

A treatment instrument includes: a sheath; and an end effector that is provided at a distal end of the sheath. The end effector is capable of gripping a living tissue and applying high frequency energy to the living tissue. The end effector includes a treatment surface, and a pair of electrodes that can grip the living tissue and apply the high frequency energy to the living tissue. The treatment surface includes a distal end area that is provided on a distal end side of the treatment surface, and another area that is provided on a proximal end side of the treatment surface. The distal end area applies, to the living tissue, high frequency energy that is higher than high frequency energy applied by the other area. One of the pair of electrodes includes a distal end portion and a proximal end portion.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

Some embodiments are directed to a skin treatment system that contains a laser generating device. A hydrogel patch may include a region, at a first side of the hydrogel patch, to be in contact with a person's skin. The region may contain an adsorbing medium (e.g., carbon black or any other substance that would have a similar effect) that, when receiving a laser beam from the laser generating device, results in Extracorporeal Shock Wave Therapy (“ESWT”) being applied to the person's skin to treat a dermatologic condition such as an epidermal or dermal tissue structure irregularity, cellulite, a stretch mark, a scar, scar-tissue, a hypertrophic scar, an acne scar, etc.

A device for controlling the energy supply to a medical instrument contains the medical instrument and an energy supply device. The energy supply device has at least a first and a second energy supply mode that can be preselected on the energy supply device and which supplies energy to the medical instrument according to a preselected energy supply mode. The energy supply device additionally has a third mode which differs from the at least two energy supply modes, can be preselected on the energy supply device, can detect an actuation of an energy supply operating element arranged on the medical instrument, and can carry out the supply of energy to the medical instrument in the first or second mode based on the detected actuation.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A surgical instrument connectable to a surgical energy module that is configured to provide a first drive signal at a first frequency range for driving a first energy modality and a second drive signal at a second frequency range for driving a second energy modality is provided. The surgical instrument can comprise a surgical instrument component configured to receive power from a direct current (DC) power source, an end effector, and a circuit. The circuit can be configured to convert the first electrical signal to a DC voltage, apply the DC voltage to the surgical instrument component, and deliver the second energy modality to the end effector according to the second drive signal. Alternatively, the circuit can be disposed within a cable assembly configured to connect the surgical instrument to the surgical energy module.
