摘要： A reservoir for supplying a cooling fluid to a medical ablation probe includes a wall defining a chamber therein, an outlet fluid port and an inlet fluid port each in fluid communication with the chamber, cooling fluid disposed within the chamber, and a thermochromic material thermally coupled to the cooling fluid. The thermochromic material is configured to exhibit a first color when the cooling fluid is below a threshold temperature, and a second color when the cooling fluid is above the threshold temperature.

摘要： An ultrapolar electrosurgery blade includes lop and bottom thin elongated conductive members in vertical, alignment and spaced apart, from one another along their lengths, a non-conductive coating covering both the top and bottom thin elongated conductive members and the space located between them to create opposing non-conductive sides of the blade with conductive cutting and ends and conductive non-cutting ends exposed, and both return and active contact layers located on each of the opposing non-conductive sides of the blade. An ultrapolar electrosurgery blade assembly having argon beam capability further includes a non-conductive tube member having a slot positioned over the top of the ultrapolar electrosurgery blade and a conductive hollow tubular member contained within at least a portion of the non-conductive tube member.

摘要： A treatment device using a high frequency according to the present invention includes: a plurality of electrodes which transfers high frequency energy to the skin; a plurality of pads each of which is provided on one surface thereof with at least one of the electrodes; and a plurality of elastic members which independently and elastically support the other surfaces of the plurality of pads, respectively, so that plurality of electrodes can be three-dimensionally and closely attached to the curved surface of the skin. Accordingly, even when treating a body region having many curves, the attachment of the electrodes is efficiently maintained. In addition, although a hand piece moves in a state in which the plurality of pads are attached to skin, the plurality of pads can be maintained in the skin attached state while actively coping with the curves.

摘要： A surgical instrument is provided that includes a first input mechanism having axial slots formed in a periphery and a second input mechanism having helical slots formed in a surface. The instrument also includes an insert having pins extending from a surface thereof, the insert coupled to the second input mechanism such that the one or more pins extend into the helical slots, and a surgical device coupled to an end. The surgical device is moved in a first degree of freedom in response to a mechanical driving force applied to both the first input mechanism and the second input mechanism, respectively, and the surgical device is moved in a second degree of freedom in response to a mechanical driving force applied to the second input mechanism while the first input mechanism is held stationary.

摘要： A method and apparatus for treating an intraosseous nerve. The method includes positioning a hollow shaft through the cortical shell of a vertebral body and into a cancellous bone region of the vertebral body. The hollow shaft includes an annular wall having a longitudinal bore therein, a proximal portion and a distal portion, and a first window extending transversely through the annular wall. An electrosurgical probe is advanced within the longitudinal bore from the proximal portion toward the distal portion. The electrosurgical probe includes a first treatment element at a distal end of the probe, wherein the first treatment element being in electrical connection with a power supply. The first treatment element is slidably disposed within the longitudinal bore so that the first treatment element is advanced radially outward from the window and shaft to affect treatment of the intraosseous nerve within the cancellous bone region.
