A surgical tool includes a drive housing, a shaft extending from the drive housing, an end effector at an end of the shaft and having opposing jaws and a cutting element, and an unclamp lockout mechanism. The unclamp lockout mechanism including a pawl rotatably mounted to the shaft and positioned proximal to a closure yoke operatively coupled to the shaft, the pawl being pivotable between a stowed position, where the pawl is received within an aperture of the shaft, and a deployed position, where the pawl protrudes out of the aperture, and a biasing device that biases the pawl toward the stowed position. When the pawl is in the stowed position, the closure yoke is movable to a proximal position over at least a portion of the pawl to open the opposing jaws. When the pawl is in the deployed position, the closure yoke is prevented from moving to the proximal position.

A surgical retractor includes a part defining a longitudinal axis. A first radiolucent blade is connected with the part. A second radiolucent blade is connected with the part. The blades are independently translatable relative to the part. At least one of the blades includes spaced apart arms that are connected via a member. The member and the arms are relatively disposed in a configuration to guide at least one surgical instrument in a selected orientation relative to a surgical site. Surgical systems, instruments, constructs, implants and methods are disclosed.

A method of stapling tissue is disclosed. The method can include obtaining a staple cartridge including a plurality of staples, wherein each staple has a base and a leg extending from the base. The stapling method can also include firing the staples from the staple cartridge, wherein the staples are fired into tissue in a staple line. The staple line can include a first portion having a first flexibility and a second portion having a second flexibility, wherein the second flexibility is different than the first flexibility. A method of stapling tissue can also include adapting an anvil with an anvil plate having an arrangement of staple-forming pockets that differs from the staple-forming pockets in the anvil.

A bearing structure includes a fixing member attached with respect to an arm of a surgical robot in a state in which a holder that is provided at a distal end of the arm is inserted inside the fixing member, a first drape that covers the arm being attachable to the fixing member, and a rotating member attached with respect to the fixing member in a slidably rotatable manner in a state in which the holder is inserted inside the rotating member, a second drape that covers the holder being attachable to the rotating member. The rotating member is rotatable together with the holder.

A surgical tool mounted to a surgical robot includes a treatment portion including a movable part that may be displaced, a main body including a slider that generates a driving force to displace the movable part, the slider generating the driving force through reciprocating motion along a linear direction, and a manual releasing tool that, when inserted into the main body, may displace the movable part, the manual releasing tool being detachably insertable into the main body.

A generator, ultrasonic device, and method for controlling a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature.

A medical instrument, for example an impact instrument, and a method for producing a medical instrument. The medical instrument includes a proximal end and a distal end. A handle and a striking face facing in a proximal direction are arranged or formed on the proximal end. A tool instrument is arranged or formed on the distal end. An instrument shaft of the instrument extends from the proximal end to the tool element. The handle is configured in the form of a hollow handle.

A surgical tool comprising a drive housing having first and second ends, a lead screw extending between the first and second ends and rotatably coupled to the first end at a drive input, a carriage mounted to the lead screw at a carriage nut and movable within the drive housing between the first and second ends, and an instrument driver arranged at an end of a robotic arm and matable with the first end. A drive output is matable with the drive input such that rotation of the drive output correspondingly rotates the drive input and the lead screw to thereby translate the carriage nut along the lead screw. A fin may be connected to the carriage and accessible by a user from an exterior of the drive housing to manually translate the carriage along the lead screw and thereby backdrive the drive output.

A surgical tool comprising a drive housing having a first end and a second end, a spline extending between the first and second ends and being rotatably coupled to the first end at a drive input, a drive gear coupled to and rotatable with the spline, a carriage movably mounted to the spline and housing an activating mechanism operatively coupled to the drive gear such that rotation of the spline actuates the activating mechanism, and a bailout mechanism arranged at the second end. The bailout mechanism may include a lever that is movable relative to the spline, from a first position, where the spline is disengaged from the lever, to a second position, where the spline engages the lever such that rotation of the lever correspondingly rotates the spline.

A tension-distribution device includes a rotationally-symmetric structure and two or more suture-engagement features associated with the rotationally-symmetric structure, the suture-engagement features being configured to receive one or more suture portions therein. The two or more suture-engagement features are evenly spaced rotationally about an axial center of the rotationally-symmetric structure.
