Claims 1 – 6 are rejected under 35 U.S.C. 103 as being unpatentable over Eid et al. (US 2017/0352292 A1) in view of Banerjee et al. (US 2007/0035511 A1)
Re claim 1:
Eid teaches 1. A dental procedure simulator (Eid, Abstract) comprising:
a computer configured to simulate a dental procedure or treatment (Eid, Abstract; [0067]),
a display housing, a display screen provided in the display housing (Eid, [0037]),
a parallel robot controlled by said computer, said parallel robot providing at least three degrees of translative freedom, said parallel robot being controlled by said computer to simulate a dental procedure or treatment by providing haptic force feedback through said parallel robot (Eid, [0017]; [0039] – [0040]; [0025]),
a handpiece operably coupled to said parallel robot by a mechanism that provides at least three degrees of rotational freedom (Eid, [0025], “(2) supporting two-hands interaction using two haptic devices”; [0034]; [0036], “series of haptic interfaces may be provided in pairs, as a left-hand interface and a right-hand interface (dominant/non-dominant)”),
said handpiece being configured to be held in a hand of a user and to be manipulated by a user in a workspace in real space (Eid, Abstract, “and the mirror instrument (non-dominant hand), and (3) a finger support mechanism using parallel manipulation”),
said computer being configured to generate images of the simulated dental procedure for display on said display screen (Eid, [0008], “The learner uses dental instruments attached to the haptic devices via custom grips, interact with 3D virtual models of teeth, gingiva, bone, calculus, instruments, etc., and feel their physical tactile properties with two hands. The learner is also provided a finger support mechanism for the intraoral fulcrum during instrumentation”; [0029], “Environment simulation module 230 maintains the graphic and haptic models that comprise the dental training environment, and synchronizes haptic device interaction”),
Eid does not explicitly disclose a partially transparent reflective element.
Banerjee teaches a compact haptic and augmented virtual reality system that produces an augmented reality environment (Banerjee, Abstract). Banerjee teaches a partially transparent reflective element provided in the display housing, said partially transparent reflective element arranged to reflect an image from said display screen to the eyes of said user, said workspace being arranged to be visible for said user through said partially transparent reflective element (Banerjee, [0037], “A graphical environment is provided by a high-resolution display screen 28 positioned by the housing 16 with respect to a partially transparent mirror 30, e.g., a half-silvered mirror. The partially transparent mirror 30 permits the user 12 to see both the virtual reality display and the user's hands, which use the haptic touch device 22 below the mirror”; [0038] – [0040]). Therefore, in view of Banerjee, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the simulator described in Eid, by providing the transparent display as taught by Banerjee, since the partially transparent mirror are used to recreate an augmented reality environment. Real time head and hand tracking enhances graphics-haptics collocation and improves immersion and realism (Banerjee, [0032]) and compact haptice and augmented virtual reality system provides head tracking, high resolution, high pixel density, and perfectly matching haptics and graphics volumes. A highly realistic virtual environment is provided. User fatigue, dizziness, and headaches are reduced or avoided (Banerjee, [0025]).
Re claim 2:
2. The A dental procedure simulator according to claim 1, wherein said display housing is configured to shield the a partially transparent reflective element from ambient light (Banerjee, fig. 1, 30; [0037], “partially transparent mirror 30, e.g., a half-silvered mirror”).
Re claim 3:
3. The dental procedure simulator according to claim 1, configured to reflect said images from said display screen to the eyes of said user by reflection on said partially transparent reflective element and configured to mix said images with a view of said workspace seen by the user through said partially transparent reflective element (Banerjee, fig. 1; [0012], “A user stands and looks through an inclined half-silvered mirror that reflects an image projected onto a horizontal screen located above the user's head”; [0024], “haptic and augmented virtual reality system that produces an augmented reality environment”).
Re claim 4:
4. The dental procedure simulator according to claim 1, wherein said images on said display screen are reflected to the eyes of the user, and wherein said workspace is simultaneously visible for the user through said partially transparent reflective element when said user looks at said partially transparent reflective element from a viewing space (Banerjee, fig. 1; [0012]; [0037], “70 percent reflection and 30 percent transmission produce a brighter graphics display and darker hand appearance than a partially transparent mirror that has 60 percent reflection and 40 percent transmission”).
Re claim 5:
5. The dental procedure simulator according to claim 1, wherein said display screen is a stereoscopic display screen and wherein said computer is configured to send stereoscopic images to said stereoscopic display screen (Banerjee, Abstract, “The system is equipped with software and devices that provide users with stereoscopic visualization and force feedback simultaneously in real time”; [0023]; [0031]).
Re claim 6:
6. The dental procedure simulator according to claim 1, wherein said partially transparent reflective element is a partially transparent mirror or a semi-transparent mirror (Banerjee, fig. 1; [0012]; [0037], “70 percent reflection and 30 percent transmission produce a brighter graphics display and darker hand appearance than a partially transparent mirror that has 60 percent reflection and 40 percent transmission”).
Claims 7 – 13 are rejected under 35 U.S.C. 103 as being unpatentable over Eid et al. (US 2017/0352292 A1) in view of Lammertse (US 8,716,973 B1)

Eid does not explicitly disclose a reference. Lammertse teaches a haptic arm comprising: a user connection element; a reference; a first linkage connecting the user connection element to the reference, where the first linkage provides at least six independent degrees of freedom, and contains an intermediate link, three force sensors, three angle sensors; a second linkage connecting the intermediate link to the reference; a third linkage connecting the intermediate link to the reference a fourth linkage connecting the intermediate link to the reference; the second, third, and fourth linkages each containing an independent actuator and position sensor (Lammertse, Abstract).

Re claim 10:
10. The dental procedure simulator according to claim 7, wherein said first sensor, said second sensor and/or said third sensor are rotary position sensors (Eid, [0036], “with three degrees of freedom, the system could use more, such as six degrees of freedom input”; [0039], “The finger support 350 can also be designed in different ways (number of segments and degrees of freedom for each)”; [0042], “a six degrees-of-freedom force sensor (3 force and 3 torque) and accelerometer”; [0051], “rotation of the handle”).

Claims 14 – 19 are rejected under 35 U.S.C. 103 as being unpatentable over Eid et al. (US 2017/0352292 A1) in view of Ben-Ur (US 6377011 B1).
Re claim 14:
Eid teaches 14. A medical procedure simulator (Eid, Abstract) comprising:
a handpiece configured to be held in a hand of a user and to be manipulated by said user in a workspace in real space (Eid, [0036], “as a left-hand interface and a right-hand interface (dominant/non-dominant)”; [0054], “The left and right-handed users would naturally need to have a different device for their dominant hand”’; [0036], “The feedback to the manipulated object may result in graphical and/or haptic deformation or location manipulation”),
a linkage controlled by a computer that is configured to simulate a medical procedure or treatment (Eid, fig. 6A shows a number of segments and three joints between 342 – 332; [0009], “haptic devices are utilized to simulate haptic feedback with both the dental instrument”),
said handpiece comprising an inner part being configured to rotate about said inner part (Eid, [0051], “The 300° rotation of the handle needs to be moved from current location on haptic device to allow for +/-150° per direction of use. The 6-DOF force feedback was not required for the probing procedure but might be desired in the scaling procedure”; [0052], “its stylus that restricts a 360 degree rotation”; fig. 4 shows a part – stylus tip and an inner part – stylus connects to the joint),
a portion, said portion being coupled to said linkage by a joint with at least two degrees of freedom (Eid, [0051], “The 300° rotation of the handle needs to be moved from current location on haptic device to allow for +/-150° per direction of use. The 6-DOF force feedback was not required for the probing procedure but might be desired in the scaling procedure”; [0052], “its stylus that restricts a 360 degree rotation”; fig. 4 shows a part – stylus tip and an inner part – stylus connects to the joint),
an inertial measurement unit mounted to said inner part and coupled to said computer (Eid, [0039], “of rotation of the movement”; [0042], “the system comprises a six degrees-of-freedom force sensor (3 force and 3 torque) and accelerometer”), and a rotary position sensor for sensing rotational movement of said outer part relative to said inner part, said rotary position sensor being coupled to said computer, at least a first portion of said rotary position sensor being mounted on said inner part (Eid, [0051], “The 300° rotation of the handle needs to be moved from current location on haptic device to allow for +/-150° per direction of use. The 6-DOF force feedback was not required for the probing procedure but might be desired in the scaling procedure”; [0052], “its stylus that restricts a 360 degree rotation”; fig. 4 shows a part – stylus tip and an inner part – stylus connects to the joint), and
said first portion being connected to said computer by a cable that is guided or supported by said inner part (Eid, [0046]).
Eid does not explicitly disclose an inner part protrudes from said outer part.
Ben-Ur (US 6377011 B1) teaches a handle module actuates handles of a user interface for various applications, including minimally invasive surgery ("MIS"). Ben-Ur teaches said handpiece comprising an inner part extending into an outer part with the outer part being configured to rotate about said inner part; a portion of said inner part protrudes from said outer part, said portion being coupled to said linkage by a joint with at least two degrees of freedom (Ben-Ur, figs. 5 – 8; fig. 13; i.e., fig. 7, 24 is protrude out of 34; fig. 5 show the 24 is rotatable to a joint; col. 9, lines 56 – 63, “being rotatable relative to each other about an axis that is perpendicular to the axis of elongation of the first and 60 second shafts”). Therefore, in view of Ben-Ur, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the simulator described in Eid, by providing the rotatable member with inner and outer members (Ben-Ur, fig. 7, 24 and 34) as taught by Ben-Ur, in order to provide a replaceable inner shaft as taught by Ben-Ur.
Re claim 15:
15. The medical procedure simulator according to claim 14, wherein said inertial measurement unit is coupled to said computer by a cable that is guided or supported by said inner part (Eid, [0036], “with three degrees of freedom, the system could use more, such as six degrees of freedom input”; [0039], “The finger support 350 can also be designed in different ways (number of segments and degrees of freedom for each)”; [0042], “a six degrees-of-freedom force sensor (3 force and 3 torque) and accelerometer”; [0051], “rotation of the handle”).
Re claim 16:
16. The medical procedure simulator according to claim 14, wherein said inner part is elongated and is connected to said joint at a first extremity of said inner part, said rotary position sensor being arranged at or near a second extremity of said inner part, said second extremity being located inside said outer part (Eid, [0036], “with three degrees of freedom, the system could use more, such as six degrees of freedom input”; [0039], “The finger support 350 can also be designed in different ways (number of segments and degrees of freedom for each)”; [0042], “a six degrees-of-freedom force sensor (3 force and 3 torque) and accelerometer”; [0051], “rotation of the handle”; Ben-Ur, col. 2, lines 26 – 51, “outer and inner shafts 524 and 526, and the smaller handle piece 528a therebetween”).
Re claim 17:
17. The medical procedure simulator according to claim 14, wherein said inertial measurement unit is configured for creating position and/or orientation data of said handpiece in real space (Eid, [0039], “of rotation of the movement”; [0042], “the system comprises a six degrees-of-freedom force sensor (3 force and 3 torque) and accelerometer”).
Re claim 18:
18. The medical procedure simulator according to claim 14, wherein said coupling of said inertial measurement unit to said computer comprises a data link from the inertial measurement unit to said computer for transmission of position and/or orientation data (Eid, [0039], “of rotation of the movement”; [0042], “the system comprises a six degrees-of-freedom force sensor (3 force and 3 torque) and accelerometer”).
Re claim 19:
19. The medical procedure simulator according to claim 14, wherein said coupling of said rotary position sensor to said computer comprises a data link from said rotary position sensor to said computer for transmission of rotary position data (Eid, [0052], “the haptic device has a small cog in its stylus that restricts a 360 degree rotation, for example restricting movement to 300degrees, in one embodiment 150+/- degrees from a resting or neutral location”).
Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over Eid et al. (US 2017/0352292 A1) in view of Ben-Ur (US 6377011 B1) as applied to claim 14 above, and further in view of Gerbi et al. (US 2003/0060927 A1).
Re claim 20:
Eid does not explicitly disclose an infinite rotating member. Gerbi teaches an input device for robotic surgery mechanically transmits a grip signal across a first joint coupling a handle to a linkage supporting the handle. The handle is removable and replaceable, allows unlimited rotation about the joint, and may optionally include a touch sensor to inhibit movement of a surgical end effector when the hand of the surgeon is not in contact with the handle. Gerbi teaches 20. The medical procedure simulator according to claim 14, wherein said outer part has infinite rotation relative to said inner part (Gerbi, Abstract, “The handle is removable and replaceable, allows unlimited rotation about the joint”). Therefore, in view of Gerbi, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the simulator described in Eid, by providing the unlimited rotation as taught by Gerbi, in order to increase the flexibility of the tool by allowing a surgeon to turn the tool in any number of rotations.
