Variable aspiration control device
An aspiration control device may include a conduit having a distal end and a proximal end and defining a conduit lumen, wherein the conduit defines a vent that is open to the conduit lumen, a coupling configured to couple the proximal end of the conduit with a vacuum source and an inner cannula such that a vacuum is supplied to each of the conduit lumen and the inner cannula, a sleeve movably disposed about the conduit and configured to move relative to the vent to achieve a desired level of vacuum delivered to the inner cannula.
System and methods for motorized injection and aspiration
A motorized injection and aspiration system and methods for its use, where the motorized injection and aspiration system comprises (a) a syringe coupled to a needle, wherein the syringe includes a plunger, (b) a cannula, (c) a tube having first and second ends, wherein the first end is coupled to the needle and the second end is coupled to the cannula, (d) a syringe driver to drive the plunger, (e) at least one foot pedal, (f) a step motor, and (g) a control unit in communication with the step motor, the syringe driver and the at least one foot pedal.
DEVICES AND METHODS FOR AUTOMATIC SUTURE
A method includes engaging a clamp over a length of tissue to be sutured. A helical needle is advanced along a length of the clamp such that the helical needle passes through the tissue to be sutured. A leading end of a suturing thread is attached at a tip of the helical needle. The leading end of the suturing thread is captured. The helical needle is retracted back through the tissue so as to leave the thread in place. The clamp is disengaged from the tissue. A device for automatic suturing includes a clamp configured to be positioned over a length of tissues to be sutured. A helical needle is configured to be advanced and retracted along a length of the clamp. The needle has a tip. A suturing thread having a leading end is attached to the tip of the helical needle.
Pedal control for robotic surgical systems
A foot pedal for a user interface of a robotic surgical system includes a frame, a lever, and a sensor system. The lever is coupled to the frame and is pivotable relative to the frame between an initial position and a fully actuated position. The sensor system has a first element associated with the frame and a second element that is associated with the lever. The sensor system is configured to determine the position of the lever relative to the frame.
High precision instrument control mode for robotic surgical systems
A foot pedal for a robotic surgical system includes a base plate, a foot plate, a first biasing member, and a second biasing member. The foot plate is pivotally coupled to the base plate and has uncompressed, partially compressed, and fully compressed positions. The first biasing member is configured to urge the foot plate towards the uncompressed position when the foot plate is between the fully compressed and uncompressed positions. The second biasing member is configured to urge the foot plate towards the uncompressed position when the foot plate is between the fully compressed and partially compressed positions. Methods for using the foot pedal to control a tool and a camera of a surgical robot are also disclosed.
System and method for driving an ultrasonic handpiece as a function of the mechanical impedance of the handpiece
An ultrasonic surgical tool system for actuating a handpiece with a tip. The frequency of the drive signal applied to the handpiece drivers is a function of the equivalent of current through the mechanical components of the handpiece and tip and the frequency responsiveness of these components.
Tissue removal device with adjustable delivery sleeve for neurosurgical and spinal surgery applications
A tissue cutting device is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. A delivery sleeve may be selectively provided that is configured to be disposed about the outer cannula for delivery of a variety of devices.
Apparatus, system and method of ultrasonic power delivery in a surgical system
The disclosed apparatus, system and method may include at least a phacoemulsification surgical console having a customizable non-linear custom phacoemulsification mode. The apparatus, system and method may include an ultrasonic delivery tip; a foot pedal; and non-transitory computing code resident on a computing memory associated with a computing processor which, when executed by the processor, causes to be executed the steps of: receiving a percentage actuation of the foot pedal; calculating, including from a non-linear algorithm, a percentage actuation for the ultrasonic delivery tip corresponded to the received percentage foot pedal actuation; and dictating the calculated percentage actuation for the ultrasonic delivery tip actuation to the ultrasonic delivery tip.
System And Method For Driving An Ultrasonic Handpiece As A Function Of The Mechanical Impedance Of The Handpiece
An ultrasonic surgical tool system for actuating a handpiece with a tip. The frequency of the drive signal applied to the handpiece drivers is a function of the equivalent of current through the mechanical components of the handpiece and tip and the frequency responsiveness of these components.
END EFFECTOR CONTROL AND CALIBRATION
Methods and apparatus for end effector control and calibration are described. The method may include detecting a signal in response to movement of a first tube relative to a second tube, the first tube driving movement of a clamp arm of the end effector. The method may further include determining a clamp arm position of the end effector relative to a ultrasonic blade of the end effector based on the signal. The method may also include adjusting a power output to the ultrasonic blade of the end effector based on the clamp arm position.
