User controller with user presence detection and related systems and methods

Cross Reference to Related Applications

The present application claims the benefit of U.S. provisional application 62/427,357 entitled "controller with user presence detection and related systems and methods" filed 2016, 11, 29, 2016 (e), hereby incorporated by reference in its entirety.

Technical Field

Various embodiments herein relate to user presence detection for multiple degree of freedom (DOF) user input devices used in systems such as robotic medical device systems.

Background

A user input device with multiple degrees of freedom requires the user to support the mass of the input device.

One example of such a known input device is shown in fig. 1-2B. Fig. 1 shows a multi-DOF user input device 8 for a user's left hand. To interface with the device 8, the user places the left palm on the body 10 of the user control 8, the index finger on the index finger interface 12 (the index finger interface 12 being movable relative to the body 10 by the rotating link 14), and the thumb in the thumb recess 16. The body 10 of the user interface 8 is connected to a multi-DOF positioning or sensing system by a linkage 18. In order to provide force and torque to move the user interface 8, both the thumb restraint 20 and the index finger restraint 22 restrain the user's hand to the device 8.

Fig. 2A and 2B illustrate the ability of the user to further input the opening/closing movement of the index finger interface 12, which index finger interface 12 is connected to the body 10 using a link 14 and a rotary joint 30. The minimum displacement 32 (shown in fig. 2A) and the maximum displacement 34 (shown in fig. 2B) may be measured and used as additional control signals. The thumb restraint 20 and index finger restraint 22 provide restraint so that the user maintains control of the body 10 while moving the grasper through its entire range of motion. Such a restraint makes it difficult for the user to disengage from the device 8 in a controlled manner while enabling the user to input another control signal.

Furthermore, in order for the user to exit the device in a controlled manner, the support for the input device must be transferred to the input device itself, or the signal output by the device must be stopped. That is, during use, the input device is supported or maintained in its operable position by the user's hand, but removal of the user's hand from the input device without the system itself providing any mechanical force can cause the input device to be pulled downward due to gravity, which can cause a robotic device or component operatively coupled to the input device to move or be actuated in an undesirable manner.

There is a need in the art for improved methods and devices for detecting the presence of a user at, on or using a user input device.

Detailed Description

Various embodiments herein relate to methods and devices for detecting the presence of a user at, on, or using a multi-DOF user input device, where the user grips the device using a gripping grip. That is, various embodiments have a sheath mounted on the input device that is configured to detect the presence of a user's hand. If the sheath detects the user's hand (or more specifically, the thumb according to some embodiments), the device sends a signal to the system (e.g., a system controller component of the system) that the user is in position and that control should be enabled (a "presence signal"). The absence of a "presence signal" can be used to stop using the device output when the hand is removed, or to lock the device in place if it is tactilely enabled.

It should be understood that the various user control embodiments herein may be used with various robotic surgical systems, where the user controls are user interfaces and are coupled to the surgical systems such that the user controls may be used to control robotic surgical devices positioned into or within a cavity of a patient. That is, the various user controller embodiments and related systems and methods disclosed herein may be incorporated into, used in conjunction with, or used as part of any other known robotic surgical system, apparatus, or method.

Accordingly, the various user control 8 embodiments disclosed or contemplated herein may be used with any robotic surgical system to operate a robotic device or components thereof (including such devices positioned in a target cavity of a patient or through an incision into patient tissue). In this way, the user manipulates the user controls 8 with her thumb and forefinger to actuate the device or its components to perform the desired procedure.

Fig. 3 illustrates a user control 8 according to one embodiment, the user control 8 having a thumb guard (also referred to as a "shroud," "sleeve," or "shroud") 40 instead of the thumb restraint as discussed above with respect to fig. 1-2B. As used herein, "sheath," "casing," "sleeve," or "shroud" is intended to mean any structure that surrounds a user's thumb on three sides while defining an opening on a fourth side through which a user can remove his thumb. The thumb guard 40 surrounds the thumb on two sides and the body 10 is restrained on the third side so that only one side is open. More specifically, the sheath 40 has a first portion 40A extending from the body 10 and a second portion 40B extending from the first portion 40A in a direction substantially transverse to the first portion 40A, thereby enclosing both sides thereof about a thumb opening 48 such that the thumb opening 48 is defined by the first portion 40A, the second portion 40B and the thumb groove 16. Alternatively, the device 8 need not have a thumb recess-in such an embodiment, the body 10 may define a third side. As a result, the thumb guard 40 and the thumb groove 16 or body 10 further define an open side 49 as shown. In contrast, the known thumb restraint 20 discussed above operates in conjunction with the thumb groove 16 to completely surround or enclose the thumb on four sides — around the entire 360 of the thumb.

In one embodiment, when the user's thumb is positioned within the thumb opening 48, the thumb guard 40 may sufficiently constrain it so that the thumb may be used to perform a "pinching motion" with the index finger to move the index finger constraint 22 away from or toward the body 10 in the direction indicated by arrow 42. As such, the thumb guard 40 may operate in a manner similar to the known thumb restraints 20 discussed above. However, unlike this constraint 20, the sheath 40 also allows for two methods of thumb withdrawal. That is, the user's thumb is not only able to retract proximally in the direction indicated by arrow 46 in the same manner as known thumb restraints 20 as much as possible, but is also able to move out of the thumb opening 48 through the open side 49 in the direction indicated by arrow 44. As can be seen in fig. 3, the potential two withdrawal directions are perpendicular to the clamping direction (indicated by arrow 42) and to each other. In this way, this configuration of the sheath 40 allows precise control of the gripping movement, while enabling the user to disengage from the device 8 by removing his thumb in a controlled and simple manner.

For purposes of illustration, the term "user control" as used herein will refer to various embodiments of a user input device that is manipulated by a user to provide input to the robotic system and thereby operate portions of the robotic system. Rather, the term "system controller" will refer to any processor, computer, or other system controller component (such as a microprocessor, etc.) that may be used to operate a system.

Fig. 4 shows another embodiment of the user control 8, the user control 8 having a sensor 51 configured to detect the presence of a user's thumb. It should be appreciated that this embodiment of the controller 8 has a thumb brace 40 substantially similar to the brace 40 described above, with the thumb brace 40 including the features and benefits described. Furthermore, in this exemplary embodiment, a user presence sensor 51 is incorporated into the sheath 40. The device 8 has a matching light emitter 50 disposed on the sheath 40 and a receiver 52 disposed on the body 10. Alternatively, the transmitter may be located on the body 10 and the receiver may be located on the sheath 40. In another alternative, two or more such sensors may be incorporated into the device 8. The emitter 50 and receiver 52 are positioned in such a way that the path of the light 54 emitted by the emitter 50 is substantially aligned with the direction of movement of the clamping movement as indicated by arrow 42. In use, the emitter 50 and receiver 52 are positioned such that when the user's thumb is not present, light (visible or otherwise) from the emitter 50 reaches the receiver 52. Conversely, when the user's thumb is present within the thumb opening 48, the path of the light 54 is blocked. The absence of this signal may then be used as an indication signal of the presence of the user (i.e., the presence of the user's thumb within the thumb opening 48), thereby indicating that the user is gripping the user control 8. Once the light path is blocked by the user's thumb, recovery of the signal (an indication signal that the user is not present) is achieved by retracting the thumb in either of the two directions indicated by arrows 44 and 46 (which are perpendicular to the gripping direction indicated by arrow 42 and the path of light 54, as described above). This configuration of the sheath 40 and sensor 51 allows the thumb to move in the gripping direction (as indicated by arrow 42) without allowing light to pass. This allows the sheath 40 to be sufficiently loose to allow easy withdrawal. That is, the size of the thumb opening 48 relative to the user's thumb does not affect the ability of the sensor 51 to detect the presence therein or the ability of the user to utilize the sheath 40 to allow the user to move the index finger constraint discussed above with a gripping motion.

Alternatively, any known sensor or sensor technology may be used with the user control 8 to detect the presence (and absence) of the user's thumb within the sheath 40.

The sensor 51 allows the user control 8 (and the system to which the control 8 is coupled) to utilize information about the presence or absence of a user's thumb to activate or deactivate the mechanical support of the user control 8. That is, the sensor 51 may be configured to send a "present" signal to a system controller (not shown) of a system (not shown) when the thumb is inserted into the sheath 40, such that the system controller deactivates any mechanical support of the user control 8. Similarly, the sensor 51 may also be configured to send an "absence" signal to the system controller (not shown) when the thumb is retracted from the sheath 40, causing the system controller to activate the mechanical support of the user control 8, thereby preventing gravity from causing the user control 8 to move in an undesired manner, which in turn prevents the controlled robotic device from also moving in an undesired manner.

Fig. 5 shows an alternative embodiment of the user control 8 with a reflective light sensor 61. That is, the user control 8 has an emitter 60 and a receiver 62 both embedded in the body 10 as shown, such that light 64 emitted from the emitter 60 returns to the receiver 62 as reflected light 66 through the nearest shield. In this configuration, the presence of the user's thumb within the sheath 40 provides a much shorter path than the sheath 40 and thus a corresponding stronger return signal than would be detected in the absence of the thumb. The signal may then be thresholded to determine the binary presence/absence of the user's thumb. That is, a predetermined threshold may be established above which the presence of the user's thumb in the sheath 40 may be interpreted such that a presence signal is sent to a system controller (not shown). In one embodiment, it will be appreciated that this embodiment has substantially the same features, exit pattern and advantages (including insensitivity to movement in the direction of the clamping movement) as the previously described embodiments.

Fig. 6 shows an exemplary known circuit used in conjunction with a sensor (such as any of the sensors 51,61 discussed above with respect to fig. 4 and 5) to detect the presence of a user's thumb within the sheath 40. In this embodiment, one or more pairs of Infrared (IR) emitters and detectors (similar to those described in fig. 4 and 5) are provided. The presence of the user's thumb blocks IR light from the emitter from reaching the detector, thereby changing the output state of the circuit. Each emitter/detector pair described detects presence using the circuit in fig. 6. When the user's thumb is not present in the device, phototransistor Q1 receives IR light from LED 1. This turns on the transistor, causing current to flow through resistor R1 and a non-zero voltage to appear on the non-inverting input (pin 5) of comparator U1. If this voltage is higher than the inverting input of U1 (set by the voltage divider of R2 and R3), the output of the comparator turns on, dropping the output voltage to 0. When the detector Q1 is blocked, the transistor is off and the circuit output is 5 volts. Alternatively, any known circuit or circuit configuration may be used for this purpose.

Fig. 7 shows another embodiment of a sensor 70 for the user control 8. In this particular embodiment, instead of a light-based technique, the sensor 70 is a known capacitive sensor 70 positioned in the body 10 as shown. The capacitive sensor 70 functions similarly to known capacitive sensors 70 for detecting the presence of a user's thumb within the sheath 40. It will be appreciated that this embodiment has substantially the same features, exit pattern and advantages (including insensitivity to movement in the direction of the clamping movement) as the previously described embodiments.

Fig. 8 illustrates an exemplary known circuit for detecting the presence of a user's thumb within the sheath 40 for use in conjunction with a capacitive sensor, such as the sensor 70 discussed above with respect to fig. 7, in accordance with another embodiment. One or more capacitive sensors, such as sensor 70 in fig. 7, are placed on the inner surface of the thumb sleeve. In use, when a user's thumb is placed in the sheath 40, the change in capacitance changes the output state of the circuit. Alternatively, any known circuit or circuit configuration that operates in conjunction with a capacitive sensor may be used for this purpose.

Fig. 12 shows another embodiment of a sensor 120 for the user control 8. In this particular embodiment, instead of optical-based or capacitance-based techniques, the sensor 120 is a known mechanical sensor 120 positioned in the body 10 as shown. The mechanical sensor 120 functions similarly to known mechanical sensors 120 for detecting the presence of a user's thumb within the sheath 40. For example, the mechanical sensor 120 may be actuated by a user's thumb pressing on the sensor 120, thereby indicating the presence of a thumb within the sheath 40. According to one embodiment, it should be appreciated that this embodiment has substantially the same features, exit pattern, and advantages (including insensitivity to movement in the direction of the clamping movement) as the previously described embodiments.

Fig. 9 illustrates an exemplary known circuit for detecting the presence of a user's thumb within the sheath 40 for use in conjunction with a mechanical sensor, such as the sensor 120 discussed above with respect to fig. 12, in accordance with another embodiment. In this embodiment, a mechanical switch (e.g., switch 120) is placed inside the thumb brace 40. In use, when the user's thumb is in position, the switch is actuated and the output state of the circuit changes. When the user's thumb is not in the sheath, the switch is open and the output of the switch is pulled up to 5 volts. V1 inverts this signal to a 0 volt output. When the thumb is placed in the sheath, the switch is pressed, which changes the output of the circuit to 5V. The switch debounce circuit is a circuit that filters out short transitions of the output when the mechanical switch is engaged and disengaged. Alternatively, any known circuit or circuit configuration that operates in conjunction with a mechanical sensor may be used for this purpose.

FIG. 10 illustrates a user control 8 having a user sensory feedback signal assembly 100 according to one embodiment. That is, this particular embodiment has a signaling assembly 100 that provides some type of sensory feedback to the user as to whether the user's thumb is within the sheath 40. In the particular embodiment shown in fig. 10, the feedback signal assembly 100 is a visual feedback assembly 100 in the form of an LED 100 disposed on the thumb guard 40. Alternatively, any form of sensory feedback signal may be used. The feedback assembly 100 provides feedback to the user as to whether the system (not shown) detects the presence of the user's thumb within the sheath 40. The feedback may be provided by a plurality of LED signals, an audible signal, or other visual signal. According to this embodiment, in use, if a user's thumb is detected, the LED 100 will illuminate, indicating that the thumb is positioned within the sheath 40. It should be understood that the user controller 8 with the user feedback signal assembly 100 may have any of the various sensor assemblies disclosed or contemplated herein. Additionally, it should be understood that the user feedback signal assembly 100 may be incorporated into any other embodiment disclosed or contemplated herein.

Fig. 11A and 11B illustrate an adjustable sheath 40 according to one embodiment. More specifically, in this particular embodiment, the sheath 40 is movable between a retracted position, shown in FIG. 11A, and an extended position, shown in FIG. 11B. In this way, the sheath 40 can be adjusted to be positioned in a retracted position relative to the body 10, wherein the thumb opening 48 has a minimum width represented by arrow 110 (as shown in fig. 11A), or can extend outwardly away from the body 10 to an extended position, wherein the thumb opening 48 has a maximum width represented by arrow 112 (as shown in fig. 11B). This adjustability enables the sheath 40 to conform to a variety of user thumb sizes while providing the user with adequate control while still being able to disengage in a controlled manner. It should also be understood that the user control 8 having the adjustable sheath 40 may have any of the various sensors or sensory feedback components disclosed or contemplated herein. Additionally, it should be understood that the adjustable sheath 40 may be incorporated into any of the other embodiments disclosed or contemplated herein.

Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
