    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 force transmission with means for winding a first cable onto a first capstan and a second cable onto a second capstan with a first axis of rotation. The first and second cables wound such that when one of the two cables is payed out, the other of the two cables is payed in. The force transmission further includes means for passing the first and cables over an idler pulley in opposite directions. The idler pulley has a second axis of rotation substantially perpendicular to the first axis of rotation. The force transmission further includes means for coupling the first cable to a lever to rotate the lever in a first direction and means for coupling the second cable to the lever to rotate the lever in a second direction opposite the first direction, the lever having a third axis of rotation substantially parallel to the second axis of rotation.

    Inventor: Thomas G. Cooper

    Abstract: In one embodiment of the invention, a link of a counter balanced arm is disclosed including, a hollow housing with a cylindrical cavity having an open end and a closed end with a small opening to allow cables to pass through; a first pivotal joint near the closed end of the hollow housing; a second pivotal join near the open end of the hollow housing; a compressible spring assembly received through the open end by the cylindrical cavity of the hollow housing; and a plug coupled to the open end of the cylindrical cavity of the hollow housing.

    Abstract: A surgical system (200) includes a surgical instrument (260) that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument (260) is coupled to motors in a surgical instrument manipulator assembly (240) via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly (240) have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly (240). From the drive output disk (545) in the surgical instrument manipulator assembly to the driven disk (964) of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.

    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: 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. A first gimbal support point is supported by a first lever having a fulcrum with one degree of rotational freedom. Second and third gimbal support points may be supported by second and third levers having fulcrums with two degrees of rotational freedom. These fulcrums may include a first axle coupled to the lever and a second axle that supports the first axle and provides the fulcrum for the supported lever. A spring may draw the second and third levers toward one another. 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: Medical, surgical, and/or robotic devices and systems often including offset remote center parallelogram manipulator linkage assemblies which constrains a position of a surgical instrument during minimally invasive robotic surgery are disclosed. The improved remote center manipulator linkage assembly advantageously enhances the range of instrument motion while at the same time reduces the overall complexity, size, and physical weight of the robotic surgical system.
