[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 63 / 295,981, filed January 3, 2022.

[0002] Technical Field The present disclosure relates to an adjustment device for positioning a uterine manipulator during a surgical procedure. [Background technology]

[0003] background A uterine manipulator is a medical instrument used to manipulate a patient's uterus during surgical procedures, such as laparoscopic gynecological surgery (e.g., total laparoscopic hysterectomy (TLH) surgery). With the distal portion of the uterine manipulator advanced through the vaginal canal and into the uterus, the uterus can be manipulated through surgeon-controlled movement of the proximal portion of the uterine manipulator. The uterine manipulator can be firmly positioned and held in place during the procedure by a uterine positioning system attached to the operating table. During such procedures, the surgeon often needs to make small adjustments to the position of the uterus via the uterine manipulator, which requires the surgeon to either leave their workstation and reposition the manipulator or ask an assistant to do so. Either scenario interrupts the procedure. Furthermore, if the surgeon asks an assistant to make adjustments, the situation becomes even more complicated because the adjustments are blind and based solely on verbal instructions from the surgeon.

[0064] Detailed Description 1 illustrates a positioning system 100 designed to position a surgical tool for performing a surgical procedure. In some embodiments, the surgical procedure is laparoscopic or robotic pelvic surgery to perform a total laparoscopic hysterectomy (TLH), and the surgical tool is a uterine manipulator 101 used to perform the TLH. The positioning system 100 is designed to be mounted on a surgical table 103 and therefore includes a mounting / powering unit 102. The positioning system 100 further includes a positioning arm 104 extending from the mounting / powering unit 102, an adjustment device 110 attached to an upper end 106 of the positioning arm 104, a remote controller 108 for controlling certain components of the adjustment device 110, and a foot pedal 112 for locking and unlocking the configuration of the positioning arm 104.

[0065] The positioning arm 104 stably supports and firmly positions the uterine manipulator 101 in place during the surgical procedure. The positioning arm 104 is embodied as a "gooseneck" structure including a rigid elbow section 114 and an adjustable section 116 to which the adjustment device 110 is attached. The adjustable section 116 includes multiple collars 118 (e.g., metal links) that are movable relative to one another to provide the adjustable section 116 with a full range of motion. The positioning arm 104 also includes an internal tension cable (e.g., a braided mechanical cable) that extends from the upper end 106 of the positioning arm to the mounting / powering unit 102.

[0066] The foot pedal 112 may be depressed to unlock the positioning arm 104. That is, depressing the foot pedal 112 releases tension from the internal tension cable (e.g., deactivates the internal tension cable) to allow manual manipulation of the adjustable section 116 when desired. Conversely, the foot pedal 112 may be released from the depressed position to tension the internal tension cable (e.g., activate the internal tension cable) to lock the configuration of the adjustable section 116. In the locked configuration, the collar 118 is fixed in position, making the positioning arm 104 rigid and immovable during the surgical procedure. Thus, in the locked configuration, the positioning arm 104 establishes a global position for the adjustment device 110 secured to the upper end 106. To lock and unlock the positioning arm 104, the mounting / powering unit 102 includes a servo motor operable to tension and release the internal tension cable within the positioning arm 104. The mounting / powering unit 102 is powered via a wired connection to a wall plug.

[0067] 2 and 3, adjusting device 110 is a robotic head that can further position (e.g., locally position) uterine manipulator 101 relative to the global position of adjusting device 110. For example, once positioning arm 104 is locked in a desired configuration to establish the global position of adjusting device 110, adjusting device 110 can be operated with remote control 108 to fine-tune the position of uterine manipulator 101 supported on adjusting device 110. Adjusting device 110 includes a lower base 122 (e.g., support unit) fixedly attached to upper end 106 of positioning arm 104, an upper adjusting unit 124 that is movable relative to base 122, and an adapter 126 that securely couples adjusting unit 124 to uterine manipulator 101.

[0068] The base 122 includes a housing 128, internal electronics 130, a rechargeable battery 132 that may be enclosed within the housing 128 for powering the adjusting device 110, and a power indicator light. Additionally, the base 122 may be directly connected to the remote control 108 via a signal cable. The internal electronics 130 may provide wireless communication with the remote control 108 and / or the adjusting unit 124, as well as wired communication with the remote control 108. The housing 128 includes a power selector 134 (e.g., a button or switch) for turning power to the adjusting device 110 on and off. The base 122 further includes an elongated receiving portion 136 (e.g., a rail or slot, shown schematically by dashed lines corresponding to an arcuate path) having a curved (e.g., arc-shaped) profile to allow the adjusting unit 124 to move in an arc (e.g., curvilinear) in the x-y plane along the elongated receiving portion 136.

[0069] Adjustment unit 124 includes a housing 138 (e.g., a base component), internal electronics 140, a connector 142 (e.g., a support component) that moves along an elongated receiving portion of base 122, and a rotational element 144 (e.g., a pivotable element) that effectively allows adapter 126 and attached uterine manipulator 101 to tilt left and right. Internal electronics 140 may provide wireless communication with remote controller 108 and / or base 122. In some embodiments, internal electronics 140 may also provide wired communication with remote controller 108.

[0070] 2 and 3, connector 142 is an elongated component (e.g., a rod, peg, or extension piece) extending from the underside of housing 138. The lower end of connector 142 is shaped to be retained within elongated receptacle 136 of base 122. Elongated receptacle 136 is formed substantially parallel to the curved profile of housing 128 in the xy plane. The curved shape of elongated receptacle 136 allows for forward / backward movement of adjustment unit 124 about the horizontal x-axis and up / down movement of adjustment unit 124 about the vertical y-axis. The forward / backward and up / down components of movement together provide an arcuate motion (arc-like movement) of adjustment unit 124. Referring to FIG. 4, in some embodiments, adjustment unit 124 can move forward (e.g., along the x-axis) a total distance 1 of up to about 6 cm to up to about 26 cm from a rearward-most position 146 (e.g., defined at connector 142) to a forward-most position 148. In some embodiments, the adjustment unit 124 can move vertically (eg, along the y-axis) a total distance h of up to about 5 cm to up to about 10 cm.

[0071] 2 and 5, rotation element 144 includes a dial 150 and an adapter mount. The adapter mount extends from dial 150 and fits securely into a corresponding receptacle on adapter 126. Dial 150 is rotatable about an internal pin through an angle β of up to about 90 degrees to up to about 270 degrees, thereby adjusting the orientation of adapter 126 and, accordingly, the orientation of uterine manipulator 101 secured to adapter 126. In some embodiments, such an angular span corresponds to a lateral range d of tip 105 of uterine manipulator 101 of about 6 cm to about 36 cm.

[0072] Adapter 126 includes a body 156 that defines a corresponding receptacle and mounting feature (e.g., a slot, receptacle, or other mounting feature) into which shaft 107 of uterine manipulator 101 can securely fit. Adapter 126 also includes a rear connection feature at which body 156 can be attached to handle 109 of uterine manipulator 101. That is, shaft 107 of uterine manipulator 101 may be detached from handle 109 of uterine manipulator 101 to allow both components to be attached to adapter 126. In some embodiments, handle 109 of uterine manipulator 101 may be discarded, in lieu of handle 109 being provided pre-assembled with body 156 of adapter 126.

[0073] Once the uterine manipulator 101 is assembled to the adapter 126, the adapter 126 is secured to the adjustment unit 124, and the positioning arm 104 is locked in the desired configuration, a remote control 108 (e.g., a joystick) may be operated at the remote user workstation to robotically manipulate the adjustment unit 124 of the adjustment device 110. For example, as described above, the adjustment unit 124 may move forward and downward along the elongated receiving portion 136, the downward movement of which results in upward movement of the tip 105 of the uterine manipulator 101 due to the curved shape of the shaft 107. Additionally, a dial 150 may be rotated to change the orientation of the adapter 126 and, correspondingly, the orientation of the uterine manipulator 101 (e.g., to tilt the uterine manipulator 101 left or right).

[0074] Although adjustment device 110 has been described and illustrated with respect to particular dimensions, sizes, shapes, arrangements, configurations, materials, and methods, in some embodiments, adjustment devices that are otherwise substantially similar in construction and function to adjustment device 110 may include one or more different dimensions, sizes, shapes, arrangements, configurations, and materials, or may be utilized in different ways.

[0075] For example, although adjusting device 110 has been described and illustrated as including an adapter 126 designed to mate with uterine manipulator 101, in some embodiments, an adjusting device that is otherwise substantially similar in construction and function to adjusting device 110 may alternatively include a different adapter designed to mate with a different uterine manipulator, such as uterine manipulator 111 shown in FIG. 6 .

[0076] Although adjustment device 110 has been described and illustrated with respect to particular numerical ranges for parameters l, h, β, and d, in some embodiments, an adjustment device that is otherwise substantially similar in construction and function to adjustment device 110 may alternatively be designed to operate based on different numerical ranges for one or more of parameters l, h, β, and d.

[0077] Although the adjusting device 110 has been described and illustrated as including a rechargeable battery 132 within the lower base 122, in some embodiments, an adjusting device that is otherwise substantially similar in construction and function to the adjusting device 110 may alternatively include a rechargeable battery within the upper adjusting unit instead of within the lower base.

[0078] 7 and 8 , in some embodiments, adjusting device 210 may be used as an alternative to adjusting device 110 to locally position uterine manipulator 101 of positioning system 200. Positioning system 200 is substantially similar in construction and function to positioning system 100, except that it includes adjusting device 210 instead of adjusting device 110. Accordingly, positioning system 200 further includes mounting / powering unit 102, positioning arm 104, remote control 108, and foot pedal 112 of positioning system 100, all of which are shown in FIG. 1 . Adjusting device 210 includes a device connector 250, by which adjusting device 210 is fixedly attached to positioning arm 104.

[0079] Once the positioning arm 104 of the positioning system 200 is locked in a desired configuration to establish the global position of the adjustment device 210, the adjustment device 210 can be operated by the remote control 108 to make fine adjustments to the position of the uterine manipulator 101 supported on the adjustment device 210. The adjustment device 210 also includes a lower motor assembly 222 (e.g., a translation assembly) fixedly mounted to the upper end 106 of the positioning arm 104, a middle motor assembly 224 fixedly mounted to the lower motor assembly 222, and an upper motor assembly 226 (e.g., an adjustment unit) fixedly mounted to the middle motor assembly 224.

[0080] The lower motor assembly 222 is operable to provide linear motion of the uterine manipulator 101 along the x-axis (e.g., in both the positive and negative horizontal x-axis directions). The motor assembly 222 includes a housing 228, a motor 232 located within the housing 228, and a translation mechanism 230 located above the housing 228. The motor 232 drives the linear motion of the translation mechanism 230. In some embodiments, the motor 232 is a brushless DC motor with a built-in planetary gear transmission. In some embodiments, one or more components of the adjusting device 210 are coupled to a separate control box 234 that provides power to the motor 232 (e.g., via a signal cable), wirelessly communicates control signals to the motor 232, and provides wired or wireless communication with the remote controller 108 (shown in FIG. 1 ). In some embodiments, the adjusting device 210 alternatively includes an on-board power source (e.g., a battery) and an on-board controller that powers and controls the motor 232 and communicates with the remote controller 108.

[0081] Translation mechanism 230 includes a linear track 238 (e.g., an elongated, substantially straight track) and a linear linkage member 240 that is slidable and translatable within linear track 238. For example, linear linkage member 240 includes a lower rail 242 that is complementarily shaped relative to an interior profile 244 (e.g., represented by dashed line 244) of linear track 238 such that rail 242 is linearly slidable and translatable along interior profile 244. Rail 242 is connected or otherwise coupled to motor 232 such that linear motion of rail 242 along the x-direction is driven by action of motor 232.

[0082] In some embodiments, motor assembly 222 optionally includes position stop 246 that limits the extent to which linear linkage 240 can translate in the +x direction. In some embodiments, rail 242 is movable along the +x direction a distance D of up to about 10 cm relative to linear track 238. Linear linkage 240 includes an upper platform 248 from which extends lower rail 242 and through which extends position stop 246. Middle motor assembly 224 is mounted to platform 248 (e.g., along a substantially flat surface 252) such that operation of lower motor assembly 222 causes middle motor assembly 224 to move linearly. In this manner, lower motor assembly 222 provides adjustment device 210 with a linear degree of freedom along the x-axis.

[0083] 9 and 10 , midsection motor assembly 224 is operable to effect arcuate motion of uterine manipulator 101 about reference point 254 (e.g., curvilinear motion with both x- and y-axis components). Reference point 254 is fixed relative to linear linkage 240 and corresponds to the location of the cervix of the patient's uterus (e.g., an average uterus depth of approximately 8 cm). Motor assembly 224 includes a housing 256 secured to platform 248 of translation mechanism 230, a motor 260 located within housing 256, and an arc-movement mechanism 258 coupled to housing 256. Motor 260 drives the arcuate motion of mechanism 258. In some embodiments, motor 260 is a brushless DC motor with a built-in planetary gear transmission. In some embodiments, control box 234 (shown in FIG. 7) provides power to motor 260 (e.g., via a signal cable), wirelessly communicates control signals to motor 260, and provides wired or wireless communication with remote controller 108 (shown in FIG. 1). In alternative embodiments, an on-board power source (e.g., a battery) and on-board controller of adjusting device 210 are provided to power and control motor 260 and to communicate with remote controller 108.

[0084] Arc translation mechanism 258 includes an arcuate coupling member 266 (e.g., a support component) that defines an arcuate track 268 (e.g., a curved recess, channel, or slot). Arc translation mechanism 258 also includes a gear 270 that is positioned within housing 256 along arcuate track 268 and that is coupled to and driven by motor 260. Gear 270 is coupled to arcuate track 268 such that movement (e.g., rotation) of gear 270 relative to arcuate track 268 moves arcuate coupling member 266 up and down through housing 256 along an arcuate path 201 constrained and defined by arcuate track 268. Motor assembly 224 further includes a coupling member 272 that secures arcuate coupling member 266 to housing 256.

[0085] Movement of arcuate connecting member 266 relative to (e.g., through) housing 256 along arcuate path 201 causes uterine manipulator 101 to perform a corresponding arcuate motion (that maintains shaft 107 of uterine manipulator 101 always about reference point 254). Constraining the movement of shaft 107 in this manner ensures that (e.g., for a given x-axis position of housing 256) tip 105 of uterine manipulator 101 is properly positioned (e.g., at a desired vertical position) within the patient's uterus. In some embodiments, movement of arcuate connecting member 266 from a first vertical position 274 shown in FIG. 9 to a second vertical position 276 shown in FIG. 10 results in vertical movement of tip 105 a distance of approximately 3 cm. As the arc-shaped connecting member 266 moves within the housing 256 along the arc-shaped path 201, a desired position (e.g., an operable position) of the tip 105 can be selected by moving the arc-shaped connecting member 266 to any desired vertical position between the first and second vertical positions 274, 276.

[0086] The upper motor assembly 226 is attached to the support base 278 of the arcuate linkage 266 (e.g., in an opening) such that operation of the middle motor assembly 224 moves the upper motor assembly 226 in an arc (shown in FIGS. 11 and 12 ). In this manner, the middle motor assembly 224 provides arcuate motion, thereby providing degrees of freedom to the adjustment device 210 along both the x-axis and the y-axis.

[0087] 11 and 12 , upper motor assembly 226 is operable to provide rotational movement of uterine manipulator 101 about reference point 254. Motor assembly 226 includes a housing 282 (e.g., a base component) attached to support base 278 of arcuate linkage member 266. For example, connecting rod 284 of motor assembly 226 extends from housing 282 through an opening in support base 278 to device linkage member 286 of motor assembly 226, which is coupled to uterine manipulator 101. Device linkage member 286 and connecting rod 284 together provide rotational mechanism 288. Motor assembly 226 further includes motor 290 located within housing 282. Motor 290 drives the rotational movement of mechanism 288. In some embodiments, motor 290 is a brushless DC motor with a built-in planetary gear transmission. In some embodiments, a control box 234 (shown in FIG. 7) provides power to the motor 290 (e.g., via a signal cable), wirelessly communicates control signals to the motor 290, and provides wired or wireless communication with the remote control 108 (shown in FIG. 1). In alternative embodiments, an on-board power source (e.g., a battery) and on-board controller of the adjusting device 210 are provided to power and control the motor 290 and to communicate with the remote control 108.

[0088] The connecting rod 284 of the rotation mechanism 288 is rotationally driven by a motor 290. The device coupling member 286 is fixedly attached to and surrounds the connecting rod 284 such that rotation of the connecting rod 284 causes rotation of the device coupling member 286. The device coupling member 286 includes a substantially cylindrical portion 296 that surrounds the connecting rod 284 and a support arm 298 (e.g., a rotation element) extending upward from the cylindrical portion 296. In some embodiments, the device coupling member 286 optionally includes a stop element 202 extending downward from the cylindrical portion 296. An adapter 206 attached to the uterine manipulator 101 is attached to the support arm 298. The support arm 298 is also positioned at an acute angle γ (see FIG. 7 ) with respect to the central axis 204 of the motor 290, thereby partially intersecting the shaft 107 of the uterine manipulator 101 with the reference point 254.

[0089] Because cylindrical portion 296 is attached to connecting rod 284, rotation of connecting rod 284 correspondingly rotates support arm 298 left and right relative to reference point 254. In some embodiments, support base 278 of arcuate coupling member 266 optionally includes two position stops 208 (only one is visible in FIGS. 11 and 12 ) located on opposite sides of central axis 204. Stop element 202 abuts position stops 208 when device coupling member 286 reaches a certain degree of rotation, such that stop elements 202 limit the range of rotation of device coupling member 286. In some embodiments, device coupling member 286 is allowed to rotate up to about 30 degrees to each side of housing 282 relative to central axis 204 of housing 282.

[0090] 7, 11, and 12, the central axis 204 of the motor 290 intersects a reference point 254 (e.g., corresponding to the cervix), thus ensuring that rotation of the uterine manipulator 101 occurs relative to the cervix. To maximize the range of rotation of the distal tip 105 of the uterine manipulator 101, the acute angle θ between the central axis 204 and a line 212 that is tangent to the shaft 107 of the uterine manipulator 101 and intersects the reference point 254 is maximized. In some embodiments, the angle θ is between about 30 degrees and about 50 degrees. Because the rotational motor assembly 226 is directly connected to the uterine manipulator 101 (e.g., via the adapter 206), the angle θ may remain fixed. Mounting the motor assembly 226 in a different configuration (e.g., between the lower motor assembly 222 and the middle motor assembly 224) can cause undesirable changes in the angle between the tangent 212 and the central axis 204 as the arcuate motion of the uterine manipulator 101 (discussed with respect to Figures 9 and 10) changes, which is unacceptable during a surgical procedure.

[0091] Upper motor assembly 224 provides coordination device 210 with a rotational degree of freedom about reference point 254. In some embodiments, control box 234 (shown in FIG. 7 ) supplies power to motor 290, wirelessly communicates control signals to motor 290, and provides wired or wireless communication with remote controller 108 (shown in FIG. 1 ). In alternative embodiments, an on-board power source (e.g., a battery) and on-board controller of coordination device 210 are provided to power and control motor 290 and communicate with remote controller 108.

[0092] In some embodiments, adjusting device 210 may be powered on and off by operation of control box 234, and yet adjusting device 210 may optionally include a power selector (e.g., a button or switch) located on housing 228 or on another component of adjusting device 210. In alternative embodiments in which adjusting device 210 includes an on-board power source (e.g., a battery) and an on-board controller, adjusting device 210 includes a power selector located on housing 228 or on another component of adjusting device 210. In some embodiments, adjusting device 210 weighs from about 2 kg to about 4 kg. Examples of materials from which housings 228, 256, 282 and components of mechanisms 230, 258, 288 may be made include steel and aluminum.

[0093] Although adjustment device 210 has been described and illustrated with respect to particular dimensions, sizes, shapes, arrangements, configurations, materials, and methods, in some embodiments, adjustment devices that are otherwise substantially similar in construction and function to adjustment device 210 may include one or more different dimensions, sizes, shapes, arrangements, configurations, and materials, or may be utilized in different ways.

[0094] 13 and 14 , in some embodiments, an adjustment device 310 may be used to locally position a uterine manipulator 111 of a positioning system 300. Positioning system 300 is substantially similar in construction and function to positioning system 100, except that it includes adjustment device 310 instead of adjustment device 110 and uterine manipulator 111 instead of uterine manipulator 101. Accordingly, positioning system 300 further includes mounting / powering unit 102, positioning arm 104, remote control 108, and foot pedal 112 of positioning system 100, all of which are shown in FIG.

[0095] Once the positioning arm 104 of the positioning system 300 is locked in a desired configuration to establish the global position of the adjustment device 310, the adjustment device 310 can be operated by the remote control 108 to make fine adjustments to the position of the uterine manipulator 111 supported on the adjustment device 310. Accordingly, the adjustment device 310 includes a device connector 350 by which the adjustment device 310 is fixedly attached to the positioning arm 104. The adjustment device 310 also includes a translation assembly 322 fixedly attached to the upper end 106 of the positioning arm 104, a rotation assembly 324 fixedly attached to the translation assembly 322, and a rotatable receiver 326 (e.g., a rotary adjustment unit) fixedly attached to the rotation assembly 324.

[0096] The translation assembly 322 is operable to provide linear movement of the uterine manipulator 111 along the x-axis (e.g., in both the positive and negative horizontal x-axis directions). The translation assembly 322 includes a rail 328 secured to the device connector 350, a back wall 338 secured to an end of the rail 328, and a horizontal support structure 330 (e.g., a carriage) linearly slidable along the rail 328. Thus, the rail 328 has a substantially rectangular shape, and the horizontal support structure 330 defines a slot 332 with a complementary shape to enable linear movement of the horizontal support structure 330 along the rail 328.

[0097] The translation assembly 322 further includes two flexible mechanical actuation cables (e.g., Bowden cables) that allow the horizontal support structure 330 to be moved in the +x direction (e.g., pushed forward) by one cable 334 (represented by dashed line 334) and in the −x direction (e.g., pulled backward) by the other cable 336 (represented by dashed line 336). Each cable 334, 336 is connected at one end to the horizontal support structure 330 and passes through a rear wall 338 to a remote motor 372 at the opposite end. Manipulation of the remote controller 108 controls the remote motor 372 via associated electronics 374, which actuates the cables 334, 336 to linearly move the horizontal support structure 330. In some embodiments, the remote motor 372 is a linear actuator. In some embodiments, the horizontal support structure 330 is movable relative to the rail 328 along the +x direction a distance of up to about 10 cm. In this manner, the translation assembly 322 provides the adjustment device 310 with a linear degree of freedom along the x-axis.

[0098] 15 and 16 , rotation assembly 324 is operable to effect rotational movement of uterine manipulator 111 about a rotation axis 340 that is parallel to the x-axis and extends through the patient's cervix. Rotation assembly 324 includes a vertical support structure 342 and a platform 344 (e.g., a rotatable support component) coupled to vertical support structure 342. Platform 344 includes a base 346 that is fixed to uterine manipulator 111 at a distal portion 370, and a connecting wall 348. To enable platform 344 to rotate (e.g., pivot) relative to translation assembly 322, rotation assembly 324 includes a pin 352 that connects connecting wall 348 of platform 344 to vertical support structure 342 of translation assembly 322.

[0099] The rotation assembly 324 further includes two flexible mechanical actuation cables 354, 356 (e.g., Bowden cables) that allow the platform 344 to rotate left and right about the rotation axis 340. Flexible cable 354 (represented by dashed line 354 in FIG. 14 ) is connected to one side of the platform 344 and can be pulled to move the platform 344 in a first rotational direction 358. Flexible cable 356 (represented by dashed line 356 in FIG. 13 ) is connected to the opposite side of the platform 344 and can be pulled to move the platform 344 in an opposite second rotational direction 360.

[0100] Each cable 354, 356 is connected at one end to the platform 346 and at the opposite end to a remote motor 376. Manipulation of the remote controller 108 controls the remote motor 376 via associated electronics 378, which actuates the cables 354, 356 to rotate the platform 346 about the pin 352. In some embodiments, the remote motor 376 is a linear actuator. In some embodiments, the platform 344 can rotate up to about 90 degrees on either side of the rotation axis 340. The rotatable receiver 326 is rotatably coupled to the platform 344. In this manner, the rotation assembly 324 provides the adjustment device 310 with a rotational degree of freedom about the rotation axis 340, which extends parallel to the x-axis.

[0101] 17 and 18, the rotatable receiver 326 is operable to provide rotational movement of the distal tip 115 of the uterine manipulator 111 about a transverse axis 123 that extends perpendicular (e.g., along the z-axis) to the central axis 117 of the uterine manipulator 111. The distal tip 115 can be articulated (e.g., pivoted) approximately 90 degrees upward about the transverse axis 123 (as shown in FIG. 18) and approximately 50 degrees downward about the transverse axis 123 (as shown in FIG. 17) by rotating the handle 119 (e.g., articulation control element) of the uterine manipulator 111 left and right relative to the central axis 117 at the pin mechanism 121.

[0102] The rotatable receiver 326 provides a seat (e.g., a holding or support component) to which the handle 119 is securely attached for rotating the handle 119. The receiver 326 includes two flexible mechanical actuation cables 362, 364 (e.g., Bowden cables) that allow the receiver 326, with the handle 119 resting thereon, to rotate left and right relative to the central axis 117. The flexible cable 362 (represented by dashed line 362 in FIG. 17 ) is connected to one side of the receiver 326 and can be pulled to rotate the receiver in a first rotational direction 366. The flexible cable 364 (represented by dashed line 364 in FIG. 18 ) is connected to the opposite side of the receiver 326 and can be pulled to rotate the receiver 326 in an opposite second rotational direction 368.

[0103] Each flexible cable 362, 364 is connected at one end to the receiver 326 and at the opposite end to a remote motor 380. Activation of the remote controller 108 controls the remote motor 380 via associated electronics 382, ​​which actuates the cables 362, 364 to rotate the receiver 326 about the pin mechanism 121. In some embodiments, the remote motor 380 is a linear actuator. In this manner, the rotatable receiver 326 provides the adjustment device 310 with a rotational degree of freedom about the central axis 117 and a lateral axis 123 extending perpendicular to the x-axis.

[0104] In contrast to uterine manipulator 101, uterine manipulator 111 includes different distal tips 115 that can be selected for use with different depths of the uterus. As a result, the cervix remains in the same position relative to handle 119, and adjustment device 310, by means of rotation assembly 324 and rotatable receiver 326, can adjust distal tip 115 at the cervix regardless of the depth of the uterus.

[0105] The remote location of motors 372, 376, 380 of adjusting device 310 advantageously reduces the weight of adjusting device 310. In some embodiments, adjusting device 310 weighs between about 0.5 kg and about 3 kg. Examples of materials from which translating assembly 322, rotating assembly 324, and rotatable receiver 326 can be made include aluminum and steel.

[0106] Although adjustment device 310 has been described and illustrated with respect to particular dimensions, sizes, shapes, arrangements, configurations, materials, and methods, in some embodiments, adjustment devices that are otherwise substantially similar in construction and function to adjustment device 310 may include one or more different dimensions, sizes, shapes, arrangements, configurations, and materials, or may be utilized in different ways.

[0107] For example, although the adjustment device 310 has been described and illustrated as including a rotatable receiver 326 designed to seat the handle 119 of the uterine manipulator 111, in some embodiments, an adjustment device that is otherwise substantially similar in construction and function to the adjustment device 310 may alternatively include a rotatable receiver 326 designed to seat a different rotatable component (e.g., a fitting) of the uterine manipulator 111 that replaces the handle 119.

[0108] Although adjustment device 310 has been described and illustrated as including remote motors 372, 376, 380 that provide actuation via mechanical actuation cables 334, 336, 354, 356, 362, 364, in some embodiments, adjustment devices that are otherwise substantially similar in construction and function to adjustment device 310 may alternatively include remote motors that provide actuation via hydraulic mechanisms.

[0109] Although adjustment device 310 has been described and illustrated as including remote motors 372, 376, 380 that provide actuation via mechanical actuation cables 334, 336, 354, 356, 362, 364, in some embodiments, an adjustment device that is otherwise substantially similar in construction and function to adjustment device 310 may alternatively include one or more local motors directly connected to the local components of assemblies 322, 324 and receiver 326.

[0110] Adjustment device 310 has been described and illustrated as including three sets of two mechanical actuation cables 334, 336; 354, 356; 362, 364, with each cable in each set effecting opposing movement of mechanisms 322, 324, 326, respectively. However, in some embodiments, an adjustment device that is otherwise substantially similar in construction and function to adjustment device 310 may alternatively include a single flexible mechanical actuation cable for each movement mechanism 322, 324, 326 that can selectively effect one of two opposing movements. In some embodiments, either cable in the set of two mechanical actuation cables 334, 336; 354, 356; or 362, 364 may be configured to effect one of two alternative opposing movements.

[0111] Remotely controlling the robotic movement of the adjustment devices 110, 210, 310 allows the surgeon to desirably position the patient's uterus (e.g., seated on the uterine manipulators 101, 111 secured to the adjustment devices 110, 210, 310) for optimal access for incision and removal without leaving the workstation where the surgeon operates the remote controller 108. Thus, the surgeon can continue to visualize the patient's pelvic region on a display screen at the robotic surgical workstation without interruption while the adjustment devices 110, 210, 310 are being remotely manipulated. Thus, such remote control of the adjustment devices 110, 210, 310 advantageously results in streamlined procedures with increased efficacy, increased precision, and reduced procedure time.

[0112] In some embodiments, any of the adjustment devices 110, 210, 310 may be provided as modular devices that can be retrofitted or otherwise assembled to the positioning arm 104 of the positioning system 100, 200, 300 at the point of care. In other embodiments, the adjustment device 110, 210, 310 may be pre-assembled with the positioning arm 104 of the positioning system 100, 200, 300.

[0113] Although adjustment devices 110, 210, 310 have been described and illustrated as allowing particular degrees of freedom, in some embodiments, adjustment devices that are otherwise substantially similar in construction and function to any of adjustment devices 110, 210, 310 may be designed to allow additional or alternative movements and / or degrees of freedom.

[0114] Accordingly, other embodiments are within the scope of the following claims.
