Some applications of the present invention generally relate to medical apparatus and methods. Specifically, some applications of the present invention relate to apparatus and methods for performing microsurgical procedures in a robotic manner.
Cataract surgery involves the removal of the natural lens of the eye that has developed an opacification (known as a cataract), and its replacement with an intraocular lens. Such surgery typically involves a number of standard steps, which are performed sequentially.
In an initial step, the patient's face around the eye is disinfected (typically, with iodine solution), and their face is covered by a sterile drape, such that only the eye is exposed. When the disinfection and draping has been completed, the eye is anesthetized, typically using a local anesthetic, which is administered in the form of liquid eye drops. The eyeball is then exposed, using an eyelid speculum that holds the upper and lower eyelids open. One or more incisions (and typically two or three incisions) are made in the cornea of the eye. The incision(s) are typically made using a specialized blade, which is called a keratome blade. At this stage, lidocaine is typically injected into the anterior chamber of the eye, in order to further anesthetize the eye. Following this step, a viscoelastic injection is applied via the corneal incision(s). The viscoelastic injection is performed in order to stabilize the anterior chamber and to help maintain eye pressure during the remainder of the procedure, and also in order to distend the lens capsule.
In a subsequent stage, known as capsulorhexis, a part of the anterior lens capsule is removed. Various enhanced techniques have been developed for performing capsulorhexis, such as laser-assisted capsulorhexis, zepto-rhexis (which utilizes precision nano-pulse technology), and marker-assisted capsulorhexis (in which the cornea is marked using a predefined marker, in order to indicate the desired size for the capsule opening).
Subsequently, it is common for a fluid wave to be injected via the corneal incision, in order to dissect the cataract's outer cortical layer, in a step known as hydrodissection. In a subsequent step, known as hydrodelineation, the outer softer epi-nucleus of the lens is separated from the inner firmer endo-nucleus by the injection of a fluid wave. In the next step, ultrasonic emulsification of the lens is performed, in a process known as phacoemulsification. The nucleus of the lens is broken initially using a chopper, following which the outer fragments of the lens are broken and removed, typically using an ultrasonic phacoemulsification probe. Further typically, a separate tool is used to perform suction during the phacoemulsification. When the phacoemulsification is complete, the remaining lens cortex (i.e., the outer layer of the lens) material is aspirated from the capsule. During the phacoemulsification and the aspiration, aspirated fluids are typically replaced with irrigation of a balanced salt solution, in order to maintain fluid pressure in the anterior chamber. In some cases, if deemed to be necessary, then the capsule is polished. Subsequently, the intraocular lens (IOL) is inserted into the capsule. The IOL is typically foldable and is inserted in a folded configuration, before unfolding inside the capsule. At this stage, the viscoelastic is removed, typically using the suction device that was previously used to aspirate fluids from the capsule. If necessary, the incision(s) is sealed by elevating the pressure inside the bulbus oculi (i.e., the globe of the eye), causing the internal tissue to be pressed against the external tissue of the incision, such as to force closed the incision.
In accordance with some applications of the present invention, a robotic system is configured for use in a microsurgical procedure, such as intraocular surgery. Typically, when used for intraocular surgery, the robotic system includes one or more robotic units (which are configured to hold tools), in addition to an imaging system, one or more displays, and a control-component unit (for example a control-component unit that includes a pair of control components, such as joysticks), via which one or more operators (e.g., healthcare professionals, such as a physician and/or a nurse) are able to control robotic units. Typically, the robotic system includes one or more computer processors, via which components of the system and the operators operatively interact with each other. The scope of the present application includes mounting one or more robotic units in any of a variety of different positions with respect to each other.
For some applications, a set of tools is provided, each of which includes a universal mount-engagement portion for engaging a tool mount of an end effector of the robotic unit, in accordance with some applications of the present invention. For some applications, the set of tools comprises a universal tool kit for use with the robotic unit that includes all tools that are typically used in a cataract procedure, a different ophthalmic procedure, and/or a different microsurgical procedure. For example, the set of tools typically includes one or more of the following tools: a keratome blade, an eye fixator, a paracentesis knife, a dispersive ophthalmic viscosurgical device (OVD) syringe, a cohesive ophthalmic viscosurgical device (OVD) syringe, a staining syringe (e.g., for staining the anterior lens with a stain such as trypan blue ophthalmic solution), a lidocaine syringe, forceps, a hydrodissection syringe, a phacoemulsification probe, a chopper, an irrigation/aspiration probe, an intraocular lens injector, an antibiotics syringe, and/or a Limbal Relaxing Incision (LRI) knife. For some applications, each of the tools includes one or more markers, which may be used to identify the tools and/or to determine the position and/or orientation of the tool.
Typically, the mount-engagement portion of the tools comprises a sleeve that is disposed around the outside of each of the tools. The sleeve includes a gear wheel, as well as a front recess and a rear recess. For some applications, at least one of the front and rear recesses has a frustoconical shape. Typically, the tool mount includes a socket for receiving the tool, as well as a tool-securement cover that is hingedly coupled to the tool-receiving socket and that is configured to secure the tool within the tool-receiving socket. Typically, in order to place the tool in the tool mount, the tool-securement cover is opened. The tool is then placed within the socket, before the tool-securement cover is closed such as to secure the tool within the tool-receiving socket.
For some applications, the tool is configured to be actuated to perform a function via a linear tool-actuation arm, which is disposed on the end effector and is configured to push a portion of the tool axially. For example, the linear tool-actuation arm may be configured to push the plunger of a syringe axially in a forward direction. For some applications, a portion of the tool is configured to be moved with respect to the patient's eye by the linear tool-actuation arm pushing a portion of the tool axially. As described hereinabove, typically, each of a plurality of different types of tools having different functions from each other includes universal mount-engagement portion. Thus, each of the tools is couplable with respect to the tool mount, in a manner that permits the tool to be rolled with respect to the tool mount. For some applications, an additional feature that facilitates use of the robotic unit with each of the plurality of tools is that the linear tool-actuation arm is configured to automatically slide and/or fold in order to accommodate a larger tool (such as a phacoemulsification probe).
For some applications, a further feature that facilitates use of the robotic unit with each of the plurality of tools is that many of the tools are actuated to perform their respective functions using the linear tool-actuation arm. For some applications, in order for one or more of the tools to be actuated using the linear tool-actuation arm, the tool includes a motion-conversion mechanism for converting the linear motion (which is applied to a portion of the tool via the linear tool-actuation arm) to a different mechanical motion such as to actuate the tool.
Typically, movement of the robotic units (and/or control of other aspects of the robotic system) is at least partially controlled by the one or more operators. For example, the operator may receive images of the patient's eye and the robotic units, and/or tools disposed therein, via a display. Based on the received images, the operator typically performs steps of the procedure. For some applications, the operator provides commands to the robotic units via a control-component unit. Typically, such commands include commands that control the position and/or orientation of tools that are disposed within the robotic units, and/or commands that control actions that are performed by the tools. For example, the commands may control a blade, a phacoemulsification tool (e.g., the operation mode and/or suction power of the phacoemulsification tool), and/or injector tools (e.g., which fluid (e.g., viscoelastic fluid, saline, etc.) should be injected, and/or at what flow rate). Alternatively or additionally, the operator may input commands that control the imaging system (e.g., the zoom, focus, and/or x-y positioning of the imaging system). For some applications, the commands include controlling an intraocular-lens-manipulator tool, for example, such that the tool manipulates the intraocular lens inside the eye for precise positioning of the intraocular lens within the eye.
Typically, the control-component unit includes one or more joysticks that are configured to correspond to respective robotic units of the robotic system. For example, the system may include first and second robotic units, and the control-component unit may include first and second joysticks to be operated by the operators right and left hands. For some applications, the control-component joysticks comprise respective control-component tools therein (in order to replicate the robotic units). Typically, the computer processor determines the XYZ location and orientation of a tip of the control-component tool, and drives the robotic unit such that the tip of the actual tool that is being used to perform the procedure tracks the movements of the tip of the control-component tool.
For some applications, the joystick includes an actuation mechanism. Typically, the actuation mechanism is disposed toward a tip of the control-component tool such that the operator can actuate the actuation mechanism without requiring movement of the operator's hand after moving the control-component tool. Further typically, the actuation mechanism is actuated by the operator performing a squeezing action. For example, the actuation mechanism may be a button, or a pressure sensitive pad. For some applications, the computer processor receives an input that is indicative of a tool that is coupled to the end effector. For example, the operator may input an indication of the tool into the computer processor. Alternatively or additionally, each of the tools may have a tool-identification component (e.g., a marker), and the computer processor may be configured to automatically derive which tool is currently coupled to the end effector by identifying the tool-identification component within an image of the tool. Further alternatively or additionally, the computer processor may be configured to automatically derive which tool is currently coupled to the end effector by analyzing an image of the tool even without using the tool-identification component.
Typically, in response to the operator actuating the actuation mechanism, the computer processor operates one or more actuation components of the robotic unit in a manner that is such as to actuate the tool that is coupled to the end effector to perform its function. For example, in response to detecting that a syringe of a certain type is currently coupled to the end effector, the computer processor may drive the linear tool-actuation arm to advance the plunger of the syringe through a given distance. Or, in response to detecting that the keratome blade is currently coupled to the end effector, the computer processor may drive the keratome blade to move in such a manner as to make an incision in the anterior capsule of the patient's eye.

In some applications, the front recess has a frustoconical shape, and the front set of rollers are configured to be disposed at an angle with respect to an axis of the tool, when the tool is securely held within the tool mount, such as to conform to the shape of the frustoconical recess.

Reference is now made to
Typically, movement of the robotic units (and/or control of other aspects of the robotic system) is at least partially controlled by one or more operators 25 (e.g., healthcare professionals, such as a physician and/or a nurse). For example, the operator may receive images of the patient's eye and the robotic units, and/or tools disposed therein, via display 24. Typically, such images are acquired by imaging system 22. Typically, the imaging system includes one or more cameras and/or one or more microscopes. For some applications, imaging system 22 is a stereoscopic imaging device and display 24 is a stereoscopic display. Based on the received images, the operator typically performs steps of the procedure. For some applications, the operator provides commands to the robotic units via control-component unit 26. Typically, such commands include commands that control the position and/or orientation of tools that are disposed within the robotic units, and/or commands that control actions that are performed by the tools. For example, the commands may control a blade, a phacoemulsification tool (e.g., the operation mode and/or suction power of the phacoemulsification tool), and/or injector tools (e.g., which fluid (e.g., viscoelastic fluid, saline, etc.) should be injected, and/or at what flow rate). Alternatively or additionally, the operator may input commands that control the imaging system (e.g., the zoom, focus, and/or x-y positioning of the imaging system). For some applications, the commands include controlling an intraocular-lens-manipulator tool, for example, such that the tool manipulates the intraocular lens inside the eye for precise positioning of the intraocular lens within the eye.

Typically, mount-engagement portion 32 of tools 21 comprises a sleeve that is disposed around the outside of each of the tools. The sleeve includes a gear wheel 80, as well as a front recess 82 and a rear recess 84. For some applications, at least one of the front and rear recesses has a frustoconical shape. For example, as shown, front recess 82 has a frustoconical shape. Typically, tool mount 34 includes a socket 86 (shown in
Typically, mount-engagement portion 32 is sized such that when the tool is secured within the tool-receiving socket (as described in further detail hereinbelow), gear wheel 80 of the mount-engagement portion is positioned such as to engage a gear wheel 90 of the tool mount. A motor 93 of robotic unit 20 is typically configured to drive the tool to roll with respect to the tool mount by driving gear wheel 90 to roll gear wheel 80, to thereby cause the tool to roll. For some applications, the tool is secured within the tool-receiving socket by front rollers 92 being placed within front recess 82 and rear rollers 94 being placed within rear recess 84. (It is noted that in order to place the rollers into the recesses, the tool may be moved with respect to the rollers as an alternative to, or in addition to, the rollers being moved with respect to the tool.) As noted above, for some applications, at least one of the front and rear recesses has a frustoconical shape. Typically, for such applications, the rollers that are configured to be placed within the frustoconical recess are disposed at an angle with respect to the axis of the tool. For example, as shown, front recess 82 has a frustoconical shape, and front rollers 92 are disposed at an angle with respect to the axis of the tool, such as to conform to the shape of the frustoconical recess.
As noted above, robotic unit 20 is typically configured to drive the tool to roll with respect to the tool mount by driving gear wheel 90 to roll gear wheel 80, to thereby cause the tool to roll. Typically, the insertion of the front rollers 92 into front recess 82 and rear rollers 94 into rear recess 84 is such that the rollers act as radial bearings during rolling of the tool.

For some applications, tool 21 is configured to be actuated to perform a function via a linear tool-actuation arm 100, which is disposed on end effector 35 and is configured to push a portion of the tool axially. Typically, the linear tool-actuation arm pushes the portion of the tool distally with respect to the tool mount and the mount-engagement portion (i.e., such that the portion of the tool distally moves distally relative to the tool mount and the mount-engagement portion.

Typically, the robotic unit receives an input that a given one of the substances should be injected into the portion of the patient's body. For example, operator 25 may provide an input to computer processor 28 indicating that a given substance is to be injected (operator 25 and computer processor 28 being shown in
As described hereinabove, typically, each of a plurality of different types of tools 21 having different functions from each other includes universal mount-engagement portion 32. Thus, each of the tools is couplable with respect to tool mount 34, in a manner that permits the tool to be rolled with respect to the tool mount. For some applications, an additional feature that facilitates use of robotic unit 20 with each of the plurality of tools is that linear tool-actuation arm 100 is configured to automatically slide and/or fold in order to accommodate a larger tool (such as phacoemulsification probe 58). For some applications, the tool-actuation arm is configured to fold automatically in response to being retracted to a given distance from tool mount 34. In this manner, the tool-actuation arm may be folded automatically such as to accommodate the insertion of a larger tool, such as a phacoemulsification probe, into the tool mount, without requiring removal and/or manual folding of the tool-actuation arm. Typically, the tool-actuation arm is configured to fold automatically by means of a spring mechanism being activated. Further typically, in response to the tool-actuation arm being moved closer to the tool mount, the tool-actuation arm is configured to automatically unfold (e.g., via a spring mechanism being activated). For some applications, rather than being configured to fold automatically, the arm is configured to be moved in a different manner such as to accommodate the insertion of a larger tool, such as a phacoemulsification probe, into the tool mount, without requiring removal and/or manual movement of the tool-actuation arm. For example, the arm may be configured to be automatically retracted, e.g., using an electromechanical actuator, a spring mechanism, etc.
For some applications, a further feature that facilitates use of robotic unit 20 with each of the plurality of tools is that many of the tools are actuated to perform their respective functions using linear tool-actuation arm 100. For some applications, in order for one or more of the tools to be actuated via using linear tool-actuation arm 100, the tool includes a motion-conversion mechanism for converting the linear motion (which is applied to a portion of the tool via linear tool-actuation arm 100) to a different mechanical motion such as to actuate the tool.

For some such applications, the imaging system includes one or more microscopic imaging units.
