A temperature sensing system for an electrosurgical instrument able to detect temperatures internal and/or external to the electrosurgical instrument. Temperatures detected by a temperature sensor are processed by a monitoring module which prompts action to reduce temperatures where appropriate. The temperature sensing system is particularly useful for electrosurgical instruments which combine rotary shaver arrangements and RF electrode arrangements, where suction is used to remove RF heated saline from the surgical site. Without monitoring the temperature of the electrosurgical instrument and/or the surgical site, there is a risk of burning the patient if the RF heated saline becomes too hot as the electrosurgical instrument may not be adequately insulated.

The present invention relates to systems for use for radio frequency ablation. The systems can include one or more of an ablation tool, power source for use with the ablation tool and a backstop for use in conjunction with the ablation tool during surgical procedures. Preferred ablation tools comprise a series of three or more blade-shaped electrodes disposed in a linear, curved, curvilinear or circular array. The backstops are useful for reducing direct physical and thermal heat transfer injuries to the patient or surgeon during procedures using radiofrequency (RF) ablation devices.

A system for performing robotic laser surgery is disclosed. The system comprises at least one surgery equipment, a surgeon terminal, and a communication module. Further, the system includes a surgical computer communicatively coupled to the at least one surgery equipment via the communication module. The surgical computer is configured to transfer data between the surgeon terminal and the at least one surgery equipment. The surgeon terminal is configured to modulate the tunable laser to conduct the surgical procedure in fully autonomous mode or semi-autonomous mode using robot controls. Further, a plurality of sensors is used to real-time data while performing surgical procedure and transmit the real-time data to the surgeon terminal.

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 method and system for lesion formation assessment in tissue that has undergone an ablation procedure. In one embodiment, a method of assessing lesion formation comprises: recording a baseline impedance measurement from an area of tissue with a medical device; ablating the area of tissue with the medical device; recording a post-treatment impedance measurement from the area of tissue with the medical device; identifying at least one amplitude characteristic of the baseline impedance measurement and identifying at least one amplitude characteristic of the post-treatment impedance measurement; comparing the at least one amplitude characteristic of the baseline impedance measurement and the at least one amplitude characteristic of the post-treatment impedance measurement; generating an indication of efficacy based on the comparison, the indication of efficacy being one of sufficient lesion formation and insufficient lesion formation; and re-ablating the area of tissue if the indication of efficacy is insufficient lesion formation.

A system for performing a microwave ablation procedure includes an ablation probe, a tracking system for tracking a position and orientation of the ablation probe, and a computing device. The computing device is configured to receive the position and orientation data of the ablation probe from the tracking system, display a graphical representation of the ablation probe on a display based on the received position and orientation data of the ablation probe, filter axial shift data from the position and orientation data of the ablation probe corresponding to axial movement of the ablation probe along a trajectory axis, and generate an alert based on the filtered axial shift data.

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.

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.

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 modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.
