Methods for selectively attaching a shaft assembly to a handle of a surgical instrument and an arm of a surgical robot are disclosed.

A neuro stimulator adapter for a tissue removal device is disclosed. In certain arrangements, the adapter includes an engagement sleeve and a hub. The engagement sleeve is fixedly connected to a portion of the hub. In certain arrangements, the hub further has a contact assembly disposed therein, the contact assembly configured to be connected to an electrical source to deliver neurostimlation to the tissue removal device at a distal end thereof.

A flexible manipulator includes an insertion portion including a tubular flexible portion, a bending portion, and a distal end portion. The flexible manipulator includes an operating unit on a proximal end side of the insertion portion, the operating unit including a first operating portion. The flexible manipulator includes a tube inside the tubular flexible portion, the tube including a through-hole spirally extending along a longitudinal axis of the tube from a proximal end to a distal end. The flexible manipulator includes a wire extending through the through-hole, a first end of the wire connected to the distal end portion and a second end of the wire connected to the first operating portion. The flexible manipulator includes an adjustment mechanism. The bending portion is a tubular body between the distal end portion and a distal end side of the tube.

A medical device for performing a surgical procedure may include an elongate member having a proximal end, a distal end, and a lumen extending therebetween. The medical device may also include a handle connected to the proximal end of the elongate member, an end effector assembly connected to the distal end of the elongate member, and a cutting device configured to extend from the end effector assembly, wherein the cutting device has a retracted configuration in which the cutting device is withdrawn into the end effector assembly and a deployed configuration in which the cutting device extends from the end effector assembly.

A robotic surgical instrument, comprising: a shaft; an end effector element; an articulation at a distal end of the shaft for articulating the end effector element, the articulation comprising a first joint permitting the end effector to adopt a range of configurations relative to the longitudinal axis of the shaft, the first joint being driveable by a first pair of driving elements; and an instrument interface at a proximal end of the shaft, comprising: a chassis formed from the securement of a first chassis portion to a second chassis portion, wherein the first pair of driving elements are secured relative to the chassis, the chassis portions being configured to be secured together by sliding the chassis portions relative to each other in a longitudinal direction parallel to the longitudinal axis of the shaft.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A surgical instrument includes a handle with a main body having a central axis, a lever pivotable around a pivot axis fixed with respect to the main body. The lever includes a finger abutment section including a lower finger rest contacting the ventral sides of a user's first and second fingers during pivoting movement of the finger abutment section towards the central axis, and an upper finger rest contacting the dorsal sides of both the fingers during pivoting movement of the finger abutment section away from the central axis; and a septum fixed to lower and upper finger rests and extending therebetween forming a separate first and second finger receiving portion for respectively receiving a first and a second fingers. The lever pivots around the pivot axis such that during pivoting of the lever, the septum central plane remains substantially coplanar with a plane parallel to the central axis.

A surgical instrument comprising an end effector, an articulation system, a firing system, a closure system, a lock system, and a control unit is disclosed. The end effector comprises a pair of movable jaws. The articulation system articulates the end effector when the articulation system is in an active state. The closure system is actuatable to move the pair of jaws. The lock system prevents the closure system from actuating when the lock system is in a locked state. The control unit controls the supply of power from a power source to the articulation system, the firing system, and the lock system. The control unit transitions the lock system to the locked state and prevents the supply of power from the power source to the firing system when the articulation system is in the active state.

A surgical instrument includes a housing, a shaft extending from the housing, an end effector assembly extending from the shaft and configured to rotate and/or articulate relative to the housing, a motor disposed within the housing and operably coupled to the end effector assembly to rotate and/or articulate of the end effector assembly relative to the housing, and a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to rotate and/or articulate of the end effector assembly relative to the housing based upon the sensed movement. The sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in an opposite direction.

An ultrasonic transducer assembly of an ultrasonic surgical instrument includes a piezoelectric stack, an ultrasonic horn secured to and extending distally from the piezoelectric stack and including a body and a nose extending distally from the body, an overmold seal formed about the body of the ultrasonic horn, and a casing disposed about the piezoelectric stack, the body of the ultrasonic horn, and the overmold seal. The casing defines a distal opening through which the nose of the ultrasonic horn extends. The overmold seal establishes a hermetic seal with the casing to define a hermetically sealed interior enclosing the piezoelectric stack and the body of the ultrasonic horn therein.
