A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector.

A modular surgical instrument is disclosed. The modular surgical instrument comprises a control interface, a shaft extending from the control interface, an end effector extending from said shaft, and a control circuit. The control circuit is configured to sense the electrical potential applied to the modular surgical instrument, determine if the sensed electrical potential is above a predetermined threshold, and adjust the operation of the modular surgical instrument when the sensed electrical potential exceeds the predetermined threshold.

The present application provides an endoscopic device having at least one shaft, which has at least one portion deflectable, having at least one deflection mechanism, which includes, arranged in series, at least one first connection member and at least one second connection member interacting for a deflection with the first connection member, having an end effector which is arranged on an end portion of the shaft and includes at least one tool piece. The endoscopic device further includes an actuation train, which extends at least partially through the shaft and which actuates the end effector and is flexible at least in the region of the deflectable portion of the shaft, and at least one movement transducer, which couples the end effector and the actuation train mechanically to each other and is configured to convert a first movement of the actuation train into a second movement of the tool piece.

The present application provides an endoscopic device having at least one shaft, which has at least one portion deflectable in at least one plane, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes, arranged in series, at least one first connection member and at least one second connection member interacting for a deflection with the first connection member, and at least one control train, which is coupled to the connection members and connected to an end portion of the shaft to adjust a deflection of the deflectable portion. At least one part of the control train in the region of the end portion of the shaft is arranged to form a loop-back.

A reusable tip for minimally invasive surgical instruments can include an end effector, a two-part hub, and a yoke. The end effector can include one or more movable portions enabling the end effector to move between first (e.g., open) and second (e.g., closed) positions via manipulation of the yoke within the hub. The hub can include a proximal hub and a distal hub coupled together. The end effector can be coupled to the distal hub, which can be made of a metal to provide high strength and secure shape to the distal hub. The proximal hub can be made of an autoclavable insulation material capable of maintaining a removable coupling with a control shaft. The proximal hub can be made of polyetheretherketone (PEEK).

Various exemplary methods, systems, and devices for controlling electrosurgical tools are provided. A surgical system includes a drive system, the drive system being configured to drive the application of energy, an electrosurgical generator; and a control system configured to be operatively coupled to the drive system. The control system is configured to receive energy from the generator, deliver the received energy from the generator to the drive system, receive first impedance data via the drive system, manipulate the first impedance data to create second impedance data that is modified from the first impedance data, and transmit the second impedance data to the generator to cause the generator to deliver energy to the control system within predefined power parameters of the generator that define a maximum amount of energy the generator can deliver to the control system.

A surgical clip applier comprising a rotatable clip cartridge is disclosed. The surgical clip applier comprises a lockout that at least locks out the crimping drive of the surgical clip applier when the rotatable clip cartridge is empty.

Surgical tools and methods are disclosed. The surgical tool has a first tip disposed relative to an axis and a second tip. The surgical tool has a first configuration wherein the first and second tips operate as forceps. The surgical tool has a second configuration wherein the first and second tips operate as scissors, wherein the surgical tool is configured to transition between the first configuration and the second configuration, at least in part, by rotation of the first tip about the axis.

A device comprising: a a pair of arms; a blade; and a blade extending mechanism including detent positions where the blade is locked into a position related to each of the detent positions. The device is capable of switching between: a configuration where the arms are free to move towards each other, and the blade is locked into a position related to a first one of the detent positions; a configuration where the arms are secured together by a securing mechanism that prevents movement of the arms towards each other; and a configuration where the arms are secured together so that the arms are prevented from moving towards each other, and the blade is locked into a position related to a second one of the detent positions so that the blade is substantially flush with or extends beyond a distal end of the arms.

A first subassembly includes a body and an ultrasonic blade. A second subassembly is configured to removably couple with the first subassembly and includes a first clamp arm and a first clamp arm actuator. The first clamp arm is configured to be located on a first side of the longitudinal axis of the body, and the first clamp arm actuator is configured to be located on a second side of the longitudinal axis, when the second subassembly is coupled with the first subassembly. The third subassembly is similar to the second subassembly except that the second clamp arm of the third subassembly is configured to be located on the second side of the longitudinal axis of the body when the third subassembly is coupled with the first subassembly.
