Reactive algorithm for surgical system
A modular surgical instrument is disclosed. The modular surgical instrument comprises a control interface, a shaft extending from the control interface, an end effector extending from said shaft, and a control circuit. The control circuit is configured to sense the electrical potential applied to the modular surgical instrument, determine if the sensed electrical potential is above a predetermined threshold, and adjust the operation of the modular surgical instrument when the sensed electrical potential exceeds the predetermined threshold.
Surgical anvil assemblies for surgical stapling instruments
A surgical anvil assembly for use with a circular stapling instrument includes an anvil center rod defining a longitudinal axis and an anvil head pivotally coupled to the anvil center rod and movable between a first operative condition and a second tilted condition. The anvil assembly further includes a locking assembly configured to selectively lock the anvil head in each of the first and second conditions.
Rod reducer ratchet lock-out mechanism
Spinal surgical procedures can benefit from a rod reduction instrument with a ratchet lock-out mechanism. The instrument can include an inner shaft, an outer housing and a ratchet mechanism. The inner shaft can include a threaded proximal portion and a distal end that includes a plurality of engagement members adapted to receive a pedicle screw. The outer housing can be slidably received over the inner shaft, and include a top sleeve and a bottom sleeve. The top sleeve can include the ratchet mechanism to selectively engage the threaded proximal portion of the inner shaft and the bottom sleeve can engage a connecting rod. The ratchet mechanism can include an engagement feature to selectively engage the threaded proximal portion of the inner shaft, and a locking mechanism to selectively lock the engagement feature of the ratchet mechanism against the threaded proximal portion of the inner shaft.
DEVICES AND METHODS FOR AIDING CONCEPTION
A conception aid for assisting in natural conception may include a platform configured for placement in a vaginal canal, wherein the platform comprises one or more capturing elements configured to collect semen. A method of aiding conception may include providing a conception aid device including one or more capturing elements, collecting semen with the one or more capturing elements wherein the one or more capturing elements is configured to contain the collected semen on the device, and positioning the device in a vaginal canal.
Simplified spring load mechanism for delivering shaft force of a surgical instrument
A connection mechanism and manufacturing method for a surgical instrument includes an inner shaft member that extends at least partially through an elongated shaft member of the instrument and defines proximal and distal ends and is selectively movable in a longitudinal direction with respect to the elongated shaft member and includes at least one aperture that extends partially along the longitudinal direction and disposed distally from the proximal end. The inner shaft member enables a drive collar member to slide on the inner shaft member and reciprocate along the longitudinal direction. A drive collar stop member slides on the inner shaft member and moves along the longitudinal direction. The drive collar stop member then moves in a direction relative to the longitudinal axis to engage the aperture and limit further longitudinal motion of the drive collar member. An inner shaft stop member limits movement of the inner shaft.
Pedal with sliding and locking mechanisms for surgical robots
A foot pedal system for controlling a surgical robotic system, the foot pedal system comprising a foot pedal assembly movably coupled to a foot pedal assembly platform. The foot pedal assembly having a foot pedal base, a foot pedal pivotally coupled to the foot pedal base, and a foot pedal platform, the foot pedal base operable to slide across the foot pedal platform along an x-axis and a y-axis to an arrangement of activation positions. The foot pedal platform operable to translate and rotate with respect to the foot pedal assembly platform to any position along the foot pedal assembly platform, and the foot pedal platform is operable to engage or disengage with the foot pedal assembly platform at the any position along the foot pedal assembly platform.
Needle device with activation force limiter
A medical instrument having an aspiration needle, handle device and an actuation force limiter. The actuation force limiter provides an active or passive force release mechanism that keeps the force from overpowering operation of the needle.
Robotically-assisted surgical suturing systems
A surgical suturing tracking system configured for use with a suturing needle is disclosed. The surgical suturing tracking system comprises a spectral light emitter, a waveform sensor, and a control circuit coupled to the waveform sensor. The control circuit is configured to cause the spectral light emitter to emit spectral light waves toward a suturing needle and a tissue structure, receive an input corresponding to the spectral light waves reflected by the needle and the tissue structure and determine a distance between the needle and the tissue structure based on the received input.
CLOSURE JOINT ENGAGEMENT FOR SURGICAL TOOL
The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. A coupling device driven by a plurality of drive disks corresponds to a first motor and a second motor. One or more processors are configured to send a low torque command to a first motor, send the low torque command to a second motor, determine whether the first motor and the second motor meet one or more hold engagement criteria, send a high torque command to the first motor in response to the first motor and the second motor meeting the one or more hold engagement criteria, and send the high torque command to the second motor in response to the first motor and the second motor meeting the one or more hold engagement criteria.
JOINT CALIBRATION FOR SURGICAL TOOL
The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. An end effector of the surgical tool is coupled to a tool driver. An actuator is driven by a motor of the tool driver and configured to drive a degree of freedom of the end effector. One or more processors are configured to receive a position command describing a desired position for the end effector, translate the desired position to a command for a joint associated with the end effector, calculate a compensation term to compensate for a source of hysteresis for backlash and/or compliance, and send a motor command for the motor coupled with the actuator based on the compensation term and the command for the end effector.
