TL;DR: In this article, an electrosurgical cutting/shearing tool and an interface coupled to the proximal end of the shaft and removably connectable to the robotic surgical system is presented.
Abstract: The present invention provides robotic surgical instruments and systems that include electrosurgical cutting/shearing tools and methods of performing a robotic surgical procedure. The surgical instruments can advantageously be used in robotically controlled minimally invasive surgical operations. A surgical instrument generally comprises an elongate shaft having a proximal end and a distal end. An end effector, for performing a surgical operation such as cutting, shearing, grasping, engaging, or contacting tissue adjacent a surgical site, is coupleable to a distal end of the shaft. Preferably, the end effector comprises a pair of scissor-like blades for cooperatively shearing the tissue. A conductor electrically communicating with at least one blade delivers electrical energy to tissue engaged by the blades. An interface coupled to the proximal end of the shaft and removably connectable to the robotic surgical system is also included.
TL;DR: A bipolar electrosurgical scissors for use in open or endoscopic surgery has a pair of opposed blade members pivotally joined to one another and to the distal end of the scissors itself by a rivet which extends through a insulated bushing member.
Abstract: A bipolar electrosurgical scissors for use in open or endoscopic surgery has a pair of opposed blade members pivotally joined to one another and to the distal end of the scissors itself by a rivet which extends through a insulated bushing member. Each of the blade members comprises a blade support and a blade itself, each fabricated from metal, such as stainless steel. The blades are affixed to their associated supports by means of a suitable adhesive or adhesive composite material such as a fiberglass reinforced epoxy exhibiting dielectric properties. Cutting is performed, steel-on-steel, without causing a short circuit between the two blade supports which themselves function as the bipolar electrodes.
TL;DR: An intraocular scissors including a handpiece which supports a detachable assembly having a pair of elongated relatively reciprocable blade members suitable for intraocular surgery is described in this article, where drive means are provided to operate the scissors in various modes including different rates of movement of the reciprocating blade member.
Abstract: An intraocular scissors including a handpiece which supports a detachable assembly having a pair of elongated relatively reciprocable blade members suitable for intraocular surgery. One of the blade members is fixedly mounted with respect to the handpiece and the other is mounted for reciprocating movement. Drive means are provided to operate the scissors in various modes including different rates of movement of the reciprocating blade member.
TL;DR: An insulated surgical scissors (20), having a monopolar or bipolar scissors construction, can be used during laparoscopic, endoscopic and open surgery for cutting and coagulating tissue as discussed by the authors.
