A surgical instrument includes a housing including an actuator disposed thereon and an elongated shaft extending therefrom. The elongated shaft includes an end effector assembly including a pair of opposing jaw members including a knife channel defined therein. An articulation section is disposed between the housing and the end effector assembly and is configured to articulate the end effector assembly upon actuation of the actuator, the articulating section and a proximal end of the knife channel defining a first distance therebetween. A knife assembly includes a knife having a length, the proximal end including an engagement feature disposed thereon. A knife drive rod is configured to engage the engagement feature to secure the knife drive rod to the knife such that the distal end of the knife extends beyond the engagement feature and wherein the knife length is less than the length of the first distance.

An arthroscopic system includes a hand piece with a motor drive. an elongate shaft assembly is detachably secured to a distal end of the hand piece, and the elongate shaft assembly includes an outer sleeve and an inner sleeve rotatably mounted in the outer sleeve. The inner sleeve couples to the motor drive when the elongate shaft assembly is attached to the hand piece, and an inner distal cutting window on the inner sleeve moves in and out of alignment with an outer distal cutting window on the outer sleeve as the motor drive rotates the inner sleeve. A distal electrode is disposed on an outer surface of the outer sleeve at a location opposite to that of the outer distal cutting window, and the outer sleeve member is rotatable relative to the hand piece when the hub is secured to the hand piece such that a user can hold the hand piece in one hand and rotate the outer sleeve to selectively place the outer distal cutting window or the distal electrode in an upward orientation relative to the user while continuing to hold the hand piece in the one hand.

A treatment device equipped with high frequency capability includes a pair of clasping jaws that serves as bipolar electrodes. Another treatment device equipped with high frequency capability includes a high-frequency knife that serves as monopolar electrode. An anti-fouling coating that minimizes or prevents adhesion of cauterized tissues is incorporated on the electrode surfaces. Durability and functioning of the anti-fouling coating is improved by one or a combination of increased coating thickness, increased density of the coating, and incorporation of glass and/or high molecular weight PFPE into the coating. The anti-fouling coating can be applied to different locations of the treatment portion, e.g., an insulated portion and a recess of an electrode, an insulated portion and a boundary portion with an electrode.

The present invention discloses the stormwater source filtration system in which the treatment location is at the first point of water collection, as close to the source of contamination as possible. This provides for a modular, flexible, linear treatment system that can adapt to the existing conditions and the existing roadway profiles. Like our road systems, this is linear and can change with the roadway. This system provides for increased storage capacity immediately adjacent to the roadway. Modular and flexible construction make this system of superior cost effectiveness versus the current filtration systems used today. The ease of maintenance and ability to quickly change the filtration media as needed will reduce long term maintenance costs versus current systems. The disclosed system may be installed in both new constructions and as an enhancement/retrofit of existing systems.

An electrosurgical generator configured to generate electrical energy to be applied to biological tissue via electrical communication with an electrosurgical instrument, the electrosurgical generator including a power source configured to activate to output the electrical energy to the electrosurgical instrument, a measurement circuit configured to measure a resistive value associated with an erodible coating deposited on a portion of the electrosurgical instrument, and a control circuit configured to compare a measured resistive value of the erodible coating to a threshold resistive value of the coating, and control activation of the power source based on the comparison between the measured resistive value and the threshold resistive value.

An end effector of an electrosurgical device may include a first body, a first electrode on the left side of the first body, and a second electrode on the right side of the first body. The first and second electrodes may be configured to receive electrosurgical energy to treat tissue in a target treatment zone. The end effector may also include a fluid aspiration port in fluid communication with a fluid path. The fluid aspiration port may be configured to remove a material from the target treatment zone.

The present invention discloses a plasma operation electrode for an otolaryngology department. The plasma operation electrode for the otolaryngology department includes a tubular loop electrode, a water absorption tube and an effluent flow guiding component. The water absorption tube is sheathed in the tubular loop electrode, a water inlet channel is formed between the water absorption tube and the tubular loop electrode. An end part, away from the handle, of the tubular loop electrode is provided with at least one water outlet hole. The effluent flow guiding component is correspondingly installed at the water outlet hole, and sealed and connected on an outer wall of the tubular loop electrode. A water injecting channel is formed between the effluent flow guiding component and the tubular loop electrode. The plasma operation electrode for the otolaryngology department has a good flow guiding effect to normal saline, and high in reliability and safety.

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.

A self-contained, battery powered transseptal crossing system is disclosed. An elongate, flexible electrically conductive needle body has a proximal end and a distal end. An insulation layer surrounds the sidewall and leaves exposed a distal electrode tip. A generator is configured to deliver RF energy to the electrode tip, and includes a processos configured to take impedance measurements at the tip to confirm contact with the intra atrial septum and / or confirm entry into the left atrium.

The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.
