A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to an approximated position.

A detachable surgical instrument (10), comprising a distal effector, a blade holder assembly, and a handle assembly (3), the blade holder assembly comprising at least a first blade holder assembly (1) and a second blade holder assembly (2), the first blade holder assembly (1) and the second blade holder assembly (2) being detachably connected to each other, or the second blade holder assembly (2) and the handle assembly (3) being detachably connected to each other, or the first blade holder assembly (1), the second blade holder assembly (2), and the handle assembly (3) being detachably connected to each other. Thus, the problem that common surgical instruments on the market are not easily cleaned after being used and cannot be reused is solved, significantly reducing the usage costs of the instruments, and providing the advantages of a simple structure, convenient assembly and disassembly, and low usage costs.

Conventional vasectomy techniques suffer from a number of disadvantages, including, for example, a substantial risk for the development of hematomas and swelling, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing a rapid, reliable, less invasive male sterilization procedure as well as vasectomy instruments and kits for use therewith.

Tissue modification instruments. In some embodiments, the instrument may comprise a shaft extending along an axis. A tissue treatment tip may be positioned at a distal end of the shaft. The tissue treatment tip may comprise one or more energy delivery elements configured to deliver tissue-modification energy. The tissue treatment tip may comprise a non-branching tip that extends away from the axis to define a tissue treatment region that is wider than a width of the shaft. The tissue treatment tip may comprise a terminal end, which may be positioned at the distal end of the instrument in some embodiments or may be positioned proximal of the distal end of the instrument.

Provided is a surgical electrode in which an end portion capable of emitting a high frequency has a surface treatment film that includes a first coating and a second film in the order mentioned. The first coating is formed by contacting a surface treatment agent (X) with or over the entirety or a part of the surface of the end portion at least, which surface treatment agent (X) contains at least an amino group-containing compound, and the second film is formed by contacting a surface treatment agent (Y) with a part or the entirety of the surface of the first coating, which surface treatment agent (Y) contains: a silicone resin (A); a compound (B) containing a metal element selected from titanium, platinum, rhodium and palladium; and an aromatic hydrocarbon-based solvent (C), and satisfies: (I) the content of the silicone resin is in a range of 90% by mass to 99.9% by mass with respect to a total solid mass of the silicone resin and the compound; and (II) a ratio (B.sub.M/A.sub.M) of a mass (B.sub.M) of the compound to a mass (A.sub.M) of the silicone resin is in a range of 0.001 to 0.111.

A method and apparatus for treatment of pulmonary conditions, including a device having an end effector sized and shaped to contact a nerve component on the exterior of a bronchial segment and apply energy to that nerve component.

The invention relates to a medical device intended to be inserted into the lumen of a cavity of the human or animal body or in the lumen of a blood vessel. The invention is characterised in that said device comprises a probe (5) suitable for delivering a treatment by the endovenous route, and, at the terminal end thereof, a hooked flexible tip (1), wherein the angle α formed between the extension of the end portion of the probe (5) and the extension of the end portion of the tip (1) is strictly less than +90°, said tip comprising means (3) for delivering a treatment. The invention is particularly applicable to the treatment of varicose veins, reticular veins and spider veins.

Embodiments relate to robotic arm assemblies. Robotic arm assembly includes an arm segment and end-effector assembly. Arm segment includes an elongated body which forms an arm segment central axis. End-effector assembly is securable to the arm segment. End-effector assembly includes an instrument assembly and first gear assembly. Instrument assembly includes an instrument and instrument gear. Instrument forms an instrument central axis. Instrument is for performing an action. Proximal end of instrument is secured to the instrument gear. First gear assembly includes a first primary gear and protrusion portion. First primary gear includes a second central axis formed through the first primary gear. Second central axis intersects with first central axis, instrument central axis, and arm segment central axis. Protrusion portion is secured to the first primary gear, and includes an opening. A portion of the proximal end of the instrument is provided in the opening and rotatable within the opening.

A method for delivering cancer therapy may comprise introducing a tissue resection device to the tissue site, using the tissue resection device to create a core of tissue, removing at least a portion of the core of tissue from the body to create a tissue cavity, and performing therapeutic management of malignant tissue via the tissue cavity.

A colpotomy system includes a colpotomy cup that extends to a distal surface and defines a longitudinal axis. The colpotomy system further includes a cutter operably coupled to the colpotomy cup and configured to travel along an arcuate path defined about the distal surface of the colpotomy cup. The cutter actuatable to separate a uterus from a vagina as the cutter rotates about the longitudinal axis of the colpotomy cup.
