Abstract: A medical instrument includes an instrument shaft with exit holes near a distal end of the shaft, a tool coupled to the distal end of the shaft, and a backend. The backend may include a mechanism that manipulates a drive element that extends through the shaft and couples to the tool, a fluid inlet, and a fluid channel assembly providing fluid communication between the fluid inlet and the proximal end of the shaft. Cleaning fluid is directed into the fluid inlet, through the fluid channel assembly, and into the shaft. A chassis or other structural piece of the backend may form part of the fluid channel assembly.

Abstract: A medical device includes a lever with an applied force position, a load position, and a fulcrum position. A first cable extends from the applied force position of the lever to a first capstan, the first cable wrapping around the first capstan. A second cable extends from the applied force position of the lever to a second capstan, the second cable wrapping around the second capstan. A rod couples the load position of the lever and a surgical end effector. The first and second capstans may be fixed to an axle. The axle may receive a rotational input from a rotary actuator. A hand wheel may be coupled to the axle. There may be a spring between a support structure and the lever to bias the lever to rotate about the fulcrum position of the lever.

Abstract: An instrument manipulator and a robotic surgical system including an instrument manipulator are provided. In one embodiment, an instrument manipulator includes a plurality of independent actuator drive modules, each of the plurality of actuator drive modules including an actuator output, wherein each of the actuator outputs are configured to independently actuate a corresponding actuator input of a surgical instrument without force input from another actuator output. The instrument manipulator further includes a frame housing the plurality of independent actuator drive modules, the frame including a distal end from which each of the actuator outputs distally protrude for engaging the corresponding actuator inputs of the surgical instrument.

Abstract: In accordance with an exemplary embodiment, a surgical instrument comprises a shaft and an actuation member extending through a bore of the shaft and operably coupled to an end effector. A sleeve is disposed around the actuation member and within the bore of the shaft. A flux conduit configured to transmit a surgical flux to the end effector is at least partially received within a negative feature of the sleeve. In accordance with another exemplary embodiment, a surgical instrument comprises a shaft, a wrist mechanism coupling an end effector to the shaft, and an actuation member operably coupled to the end effector. A sleeve surrounds the actuation member and has a straight passage. A flux conduit operably coupled to the end effector is received within the straight passage. A portion of the flux conduit is slack in a region of the shaft through which the sleeve does not extend.

Abstract: A medical instrument includes a roll mechanism that rotates an instrument shaft. The roll mechanism may include a first gear coupled to the instrument shaft and meshed with a second gear. One of gears may be a spur gear while the other gear may be a beveloid gear. Further, the spur gear and the beveloid gear may be in a gear train containing a compressible gear, e.g., a gear with an inner center piece, an outer ring, and a flexible interconnecting structure between the inner center piece and the outer ring. With a compressible gear, an interference fit of in the gear train may be within manufacturing variations of the gear train, and the compressible gear may deflect radially away from the interference fit.

Abstract: A force transmission transmits forces received by three levers to an input gimbal plate having three support points. The input gimbal play may in turn transmit the force to a wrist assembly coupled to a surgical tool. The three axes of rotation for the three levers are parallel. Two of the levers may have half-cylinder surfaces at an end of the lever to receive a support point of the input gimbal plate. Two of the levers may be supported with one degree of rotational freedom orthogonal to the axis of rotation of the fulcrum. A spring may draw the second and third levers toward one another. Two levers may have stops that bear against the support points. The force transmission may include a parallelogram linkage that includes a rocker link pivotally coupled to the first lever and having a flat surface that supports the first gimbal support point.

Abstract: An actuation mechanism for a medical instrument includes a pinion and a face gear that move a push-pull element. The pinion has a mounting that permits rotation of the pinion by an external control system such as a robot. The face gear meshes with the pinion. The push-pull element may have a proximal end coupled to the face gear and a distal end coupled to a tool at a distal end of an instrument shaft. A manipulator coupled for manual rotation of the actuation mechanism may include a slip clutch to prevent manual application of excessive force to the actuation mechanism.

Abstract: A surgical system includes a surgical instrument that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument is coupled to motors in a surgical instrument manipulator assembly via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly. From the drive output disk in the surgical instrument manipulator assembly to the driven disk of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.
