`SURGICAL INSTRUMENT WITH SHIFTABLE TRANSMISSION
`
`CROSS-REFERENCES TO RELATED APPLICATIONS
`
`[0001] This application claims the benefit of U.S. Provisional Application No. 61/973,257,
`
`filed March 31, 2014, which is incorporated by reference herein.
`
`BACKGROUND OF THE INVENTION
`
`[0002] Minimally invasive medical techniques are intended to reduce the amount of
`
`extraneous tissue that is damaged during diagnostic or surgical procedures, thereby reducing
`
`patient recovery time, discomfort, and deleterious side effects. One effect of minimally
`
`invasive surgery, for example, is reduced post-operative hospital recovery times. Because the
`
`average hospital stay for a standard surgery is typically significantly longer than the average
`
`stay for an analogous minimally invasive surgery, increased use of minimally invasive
`
`techniques could save millions of dollars in hospital costs each year. While many of the
`
`surgeries performed each year in the United States could potentially be performed in a
`
`minimally invasive manner, only a portion of the current surgeries use these advantageous
`
`techniques due to limitations in minimally invasive surgical instruments and the additional
`
`surgical training involved in mastering them.
`
`[0003] Minimally invasive telesurgical systems have been developed to increase a
`
`surgeon's dexterity and avoid some of the limitations on traditional minimally invasive
`
`techniques. In telesurgery, the surgeon uses some form of remote control (e.g. , a
`
`servomechanism or the like) to manipulate surgical instrument movements, rather than
`
`directly holding and moving the instruments by hand. In telesurgery systems, the surgeon
`
`can be provided with an image of the surgical site at a surgical workstation. While viewing a
`
`two or three dimensional image of the surgical site on a display, the surgeon performs the
`
`surgical procedures on the patient by manipulating master control devices, which in turn
`
`control motion of the servo-mechanically operated instruments.
`
`[0004] The servomechanism used for telesurgery will often accept input from two master
`
`controllers (one for each of the surgeon's hands) and may include two or more robotic arms
`
`on each of which a surgical instrument is mounted. Operative communication between
`
`Ethicon Exhibit 2005.003
`Intuitive v. Ethicon
`IPR2018-01703
`
`
`
`master controllers and associated robotic arm and instrument assemblies is typically achieved
`
`through a control system. The control system typically includes at least one processor that
`
`relays input commands from the master controllers to the associated robotic arm and
`
`instrument assemblies and back from the instrument and arm assemblies to the associated
`
`master controllers in the case of, for example, force feedback or the like. One example of a
`
`robotic surgical system is the DA VINCI® system available from Intuitive Surgical, Inc. of
`
`Sunnyvale, California, USA.
`
`[0005] A variety of structural arrangements can be used to support the surgical instrument
`
`at the surgical site during robotic surgery. The driven linkage or "slave" is often called a
`
`robotic surgical manipulator, and exemplary linkage arrangements for use as a robotic
`
`surgical manipulator during minimally invasive robotic surgery are described in U.S. Pat.
`
`Nos. 7,594,912; 6,758,843; 6,246,200; and 5,800,423; which are incorporated herein by
`
`reference. These linkages often make use of a parallelogram arrangement to hold an
`
`instrument having a shaft. Such a manipulator structure can constrain movement of the
`
`instrument so that the instrument pivots about a remote center of manipulation positioned in
`
`space along the length of the rigid shaft. By aligning the remote center of manipulation with
`
`the incision point to the internal surgical site (for example, with a trocar or cannula at an
`
`abdominal wall during laparoscopic surgery), an end effector of the surgical instrument can
`
`be positioned safely by moving the proximal end of the shaft using the manipulator linkage
`
`without imposing potentially dangerous forces against the abdominal wall. Alternative
`
`manipulator structures are described, for example, in U.S. Pat. Nos. 7,763,015; 6,702,805;
`
`6,676,669; 5,855,583; 5,808,665; 5,445,166; and 5,184,601; which are incorporated herein by
`
`reference.
`
`[0006] A variety of structural arrangements can also be used to support and position the
`
`robotic surgical manipulator and the surgical instrument at the surgical site during robotic
`
`surgery. Supporting linkage mechanisms, sometimes referred to as set-up joints, or set-up
`
`joint arms, are often used to position and align each manipulator with the respective incision
`
`point in a patient's body. The supporting linkage mechanism facilitates the alignment of a
`
`surgical manipulator with a desired surgical incision point and targeted anatomy. Exemplary
`
`supporting linkage mechanisms are described in U.S. Pat. Nos. 6,246,200 and 6,788,018,
`
`which are incorporated herein by reference.

`Ethicon Exhibit 2005.004

`IPR2018-01703
`
`
`
`[0007] While the new telesurgical systems and devices have proven highly effective and
`
`advantageous, still further improvements are desirable. In general, improved minimally
`
`invasive robotic surgery systems are desirable. Often, new surgical instruments are
`
`developed for use on existing telesurgical system platforms. Thus, the instrument is required
`
`to adapt to the telesurgical system, since development of a new telesurgical system for a
`
`particular surgical application is cost prohibitive. However, issues arise when existing
`
`telesurgical platforms do not have the required amount of motor outputs for all of the
`
`mechanisms of a particular surgical instrument. Thus, there is a need to adapt new surgical
`
`devices to existing telesurgical systems without limiting the surgical capabilities and without
`
`requiring modification to the existing telesurgical systems.
`
`BRIEF SUMMARY OF THE INVENTION

`the effector body and the surgical end effector. The transmission may be configured to shift
`
`coupling of the first motor interface between only a portion of the plurality of effector
`
`mechanisms and associated DOFs.
`
`[0009] Many embodiments are directed to a surgical tool comprising an elongated shaft
`
`having a proximal end and distal end. A surgical end effector is located at the distal end of
`
`the shaft. The surgical end effector has a plurality of end effector components each
`
`associated with a unique mechanical degree of freedom. The plurality of end effector
`
`components has a first end effector component and a second end effector component. A
`
`drive mechanism is located at the proximal end of the shaft. The drive mechanism has a first
`
`motor interface and a transmission. The transmission includes a shift mechanism movable

`second output shaft that extends within the main shaft.
`
`[0031]
`
`In many embodiments, the first, second, and third gear trains may be arranged along
`
`a common axis that is parallel with the camshaft.
`
`[0032] Many embodiments are directed to a method for shifting a transmission of a
`
`remotely controlled surgical apparatus. In the method, a transmission of a surgical device is
`
`shifted to engage one of a plurality of shiftable effector outputs to a surgical end effector of
`
`the surgical device. The surgical device may include a plurality of non-shiftable outputs. The
`
`surgical device may be connected to a remote controlled arm. The remote controlled arm

`[0037]
`
`In many embodiments, the camshaft is rotated to move a plurality of rocker arms
`
`that engage a plurality of gear trains of the transmission.
`
`[0038]
`
`In many embodiments, rotating the camshaft causes at least one of the non-engaged
`
`gear trains to become locked.
`
`[0039]
`
`In many embodiments, shifting can only occur sequentially along the plurality of
`
`gear trains.
`

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`[0051]
`
`In the following description, various embodiments of the present invention will be
`
`described. For purposes of explanation, specific configurations and details are set forth in
`
`order to provide a thorough understanding of the embodiments. However, it will also be
`
`apparent to one skilled in the art that the present invention may be practiced without the
`
`specific details. Furthermore, well-known features may be omitted or simplified in order not
`
`to obscure the embodiment being described.
`
`[0052]
`
`I. Minimally Invasive Teleassisted Surgery System
`
`[0053] Referring now to the drawings, in which like reference numerals represent like parts
`
`throughout the several views, FIG. 1 is a plan view illustration of a Minimally Invasive
`
`Robotic Surgical (MIRS) system 10, typically used for performing a minimally invasive
`
`diagnostic or surgical procedure on a Patient 12 who is lying down on an Operating table 14.
`
`The system can include a Surgeon's Console 16 for use by a Surgeon 18 during the
`
`Ethicon Exhibit 2005.010
`Intuitive v. Ethicon
`IPR2018-01703
`
`
`
`procedure. One or more Assistants 20 may also participate in the procedure. The MIRS
`
`system 10 can further include a Patient Side Cart 22 (surgical robot) and an Electronics
`
`Cart 24. The Patient Side Cart 22 can manipulate at least one removably coupled tool
`
`assembly 26 (hereinafter simply referred to as a "tool") through a minimally invasive incision
`
`in the body of the Patient 12 while the Surgeon 18 views the surgical site through the
`
`Console 16. An image of the surgical site can be obtained by an endoscope 28, such as a
`
`stereoscopic endoscope, which can be manipulated by the Patient Side Cart 22 to orient the
`
`endoscope 28. The Electronics Cart 24 can be used to process the images of the surgical site
`
`for subsequent display to the Surgeon 18 through the Surgeon's Console 16. The number of
`
`surgical tools 26 used at one time will generally depend on the diagnostic or surgical
`
`procedure and the space constraints within the operating room among other factors. If it is
`
`necessary to change one or more of the tools 26 being used during a procedure, an
`
`Assistant 20 may remove the tool 26 from the Patient Side Cart 22, and replace it with
`
`another tool 26 from a tray 30 in the operating room.
`
`[0054] FIG. 2 is a perspective view of the Surgeon's Console 16. The Surgeon' s
`
`Console 16 includes a left eye display 32 and a right eye display 34 for presenting the
`
`Surgeon 18 with a coordinated stereo view of the surgical site that enables depth perception.
`
`The Console 16 further includes one or more input control devices 36, which in turn cause
`
`the Patient Side Cart 22 (shown in FIG. 1) to manipulate one or more tools. The input
`
`control devices 36 can provide the same degrees of freedom as their associated tools 26
`
`(shown in FIG. 1) to provide the Surgeon with telepresence, or the perception that the input
`
`control devices 36 are integral with the tools 26 so that the Surgeon has a strong sense of
`
`directly controlling the tools 26. To this end, position, force, and tactile feedback sensors
`
`(not shown) may be employed to transmit position, force, and tactile sensations from the
`
`tools 26 back to the Surgeon's hands through the input control devices 36.
`
`[0055] The Surgeon's Console 16 is usually located in the same room as the patient so that
`
`the Surgeon may directly monitor the procedure, be physically present if necessary, and
`
`speak to an Assistant directly rather than over the telephone or other communication medium.
`
`However, the Surgeon can be located in a different room, a completely different building, or
`
`other remote location from the Patient allowing for remote surgical procedures.
`
`[0056] FIG. 3 is a perspective view of the Electronics Cart 24. The Electronics Cart 24 can
`
`be coupled with the endoscope 28 and can include a processor to process captured images for
`
`Ethicon Exhibit 2005.011
`Intuitive v. Ethicon
`IPR2018-01703
`
`
`
`subsequent display, such as to a Surgeon on the Surgeon's Console, or on another suitable
`
`display located locally and/or remotely. For example, where a stereoscopic endoscope is
`
`used, the Electronics Cart 24 can process the captured images to present the Surgeon with
`
`coordinated stereo images of the surgical site. Such coordination can include alignment
`
`between the opposing images and can include adjusting the stereo working distance of the
`
`stereoscopic endoscope. As another example, image processing can include the use of
`
`previously determined camera calibration parameters to compensate for imaging errors of the
`
`image capture device, such as optical aberrations.
`
`[0057] FIG. 4 diagrammatically illustrates a robotic surgery system 50 (such as MIRS
`
`system 10 of FIG. 1). As discussed above, a Surgeon's Console 52 (such as Surgeon's
`
`Console 16 in FIG. 1) can be used by a Surgeon to control a Patient Side Cart (Surgical
`
`Robot) 54 (such as Patent Side Cart 22 in FIG. 1) during a minimally invasive procedure.
`
`The Patient Side Cart 54 can use an imaging device, such as a stereoscopic endoscope, to
`
`capture images of the procedure site and output the captured images to an Electronics Cart 56
`
`(such as the Electronics Cart 24 in FIG. 1). As discussed above, the Electronics Cart 56 can
`
`process the captured images in a variety of ways prior to any subsequent display. For
`
`example, the Electronics Cart 56 can overlay the captured images with a virtual control
`
`interface prior to displaying the combined images to the Surgeon via the Surgeon's
`
`Console 52. The Patient Side Cart 54 can output the captured images for processing outside
`
`the Electronics Cart 56. For example, the Patient Side Cart 54 can output the captured
`
`images to a processor 58, which can be used to process the captured images. The images can
`
`also be processed by a combination the Electronics Cart 56 and the processor 58, which can
`
`be coupled together to process the captured images jointly, sequentially, and/or combinations
`
`thereof. One or more separate displays 60 can also be coupled with the processor 58 and/or
`
`the Electronics Cart 56 for local and/or remote display of images, such as images of the
`
`procedure site, or other related images.
`
`[0058] FIGS. 5A and 5B show a Patient Side Cart 22 and a surgical tool 62, respectively.
`
`The surgical tool 62 is an example of the surgical tools 26. The Patient Side Cart 22 shown
`
`provides for the manipulation of three surgical tools 26 and an imaging device 28, such as a
`
`stereoscopic endoscope used for the capture of images of the site of the procedure.
`
`Manipulation is provided by robotic mechanisms having a number of robotic joints. The
`
`imaging device 28 and the surgical tools 26 can be positioned and manipulated through
`
`incisions in the patient so that a kinematic remote center is maintained at the incision to
`
`Ethicon Exhibit 2005.012
`Intuitive v. Ethicon
`IPR2018-01703
`
`
`
`minimize the size of the incision. Images of the surgical site can include images of the distal
`
`ends of the surgical tools 26 when they are positioned within the field-of-view of the imaging
`
`device 28. Each tool 26 is detachable from and carried by a respective surgical manipulator
`
`31, which is located at the distal end of one or more of the robotic joints. The surgical
`
`manipulator 31 provides a moveable platform for moving the entirety of a tool 26 with
`
`respect to the Patient Side Cart 22, via movement of the robotic joints. The surgical
`
`manipulator 31 also provides power to operate the tool 26 using one or more mechanical
`
`and/or electrical interfaces. An example of such a carriage assembly is found at U.S. Patent
`
`Publication No. US 2013/0325034, (Atty. Docket No. ISRG04330/US), which is
`
`incorporated by reference.
`
`[0059] FIG. 6 is a simplified schematic diagram of a telesurgically controlled surgery
`
`system surgical system 100. The surgical system 100 includes a surgeon console 102, which
`
`for example can be the Surgeon's Console 52. The surgeon console 102 drives a patient side
`
`cart 104, which for example can be the Patient Side Cart 22. The patient side cart 104
`
`includes a surgical manipulator 106, which for example can be the surgical manipulator 31.
`
`[0060] The surgical manipulator 106 includes a motor unit 108 and a surgical tool 110.
`
`The motor unit 108 is a carriage assembly that holds 5 motors. In some embodiments only 5
`
`motors are used, while in other embodiments more or less than 5 motors can be used. Here,
`
`the motor unit 108 includes a plurality of motors, which can be assigned to different
`
`mechanisms. Here, the motor unit 108 includes a power motor 112, camshaft motor 114,
`
`pitch motor 116, yaw motor 118, and low-force grip motor 120, although these motors can be
`
`used for different purposes depending on the attached instrument. Generally, each motor is
`
`an electric motor that mechanically and electrically couples with corresponding inputs of the
`
`surgical tool 110. In some embodiments, the motor unit 108 may be located at a proximal
`
`end of the surgical tool 110 in a shared chassis with the surgical tool, as generally depicted by
`
`the proximal housing shown at FIG. 5B.
`
`[0061] The tool 110 for example, can be the tool 26 described above. An example of a tool
`
`usable as tool 110 is at Int'l. Pub. No. WO 2011/060318 (Attorney Docket No.:
`
`ISRG02360/PCT), which is incorporated by reference. Here, the tool 110 is an elongated
`
`effector unit 122 that includes three discrete inputs that each mechanically couple with the
`
`pitch motor 116, yaw motor 118, and a low-force grip motor 120 by way of the surgical
`
`Ethicon Exhibit 2005.013
`Intuitive v. Ethicon
`IPR2018-01703
`
`
`
`manipulator 106. The tool 110 also includes a transmission 124, which mechanically couples
`
`with the power motor 112 and the camshaft motor 114.
`
`[0062] A surgical end effector 126 is located at the distal end of the effector unit 122. The
`
`surgical end effector 126 and effector unit 122 are connected by way of a moveable wrist.
`
`An example of such a wrist is shown at U.S. Patent Publication No. US 201 1/01 18709
`
`(Attorney Docket No. ISRG02350/US), which is incorporated by reference herein. In
`
`simplistic terms, the surgical end effector can be characterized by a plurality of discrete but
`
`interrelated mechanisms, with each mechanism providing a degree of freedom (DOF) for the
`
`surgical end effector 126. As used herein, a DOF is one or more interrelated mechanisms for
`
`affecting a corresponding movement. The DOFs endow the surgical end effector 126 with
`
`different modes of operation that can operate concurrently or discretely. For example, the
`
`wrist enables the surgical end effector 126 to pitch and yaw with respect to the surgical
`
`manipulator 106, and accordingly includes a pitch DOF 128 and a yaw DOF 130. The
`
`surgical end effector 126 also includes a roll DOF 132 rotating surgical end effector about an
`
`elongated axis.
`
`[0063] The surgical end effector 126 may include a clamping and cutting m
