摘要:
A surgical instrument includes a rotatable electrical coupling assembly having a first part and a second part that electrically couple and rotate relative to each other. The second part is carried by and rotates with a tube collar coupled to a transducer. A portion of the transducer is inserted through an aperture of the second part, but does not contact the second part. The first part of the assembly may electrically couple to the second part via pogo pins, brush contacts, or ball bearings. Alternatively, the first part may comprise conductive channels formed in the casing. The second part may comprise a rotatable drum with a conductive trace. In some versions, one or more components may comprise MID components. In another version, the rotatable electrical coupling assembly comprises a rotatable PC board and brush contact. Further still, a circuit board may be provided with the transducer inside a transducer casing.

A system includes a medical device and a charging device. A sterile barrier may be interposed between the medical device and the charging device. The medical device includes an integral power source and an active element. The charging device is configured to charge the integral power source. The charging device may charge the integral power source through direct contact between features of the charging device and features the medical device. The charging device may alternatively charge the integral power source wirelessly, such as through inductive coupling. The medical device may include conductive prongs that are retained by the charging device. The charging device may physically couple with the medical device via magnets. The medical device and the charging device may be provided together in a sterile package as a kit. The kit may also include a reclamation bag to facilitate reclamation of electrical components.
摘要:
An aspiration clot retrieval catheter to have profiled guidewire for deliverability that transitions at a proximal joint to a distal tubular section with a lumen for directing aspiration and facilitating the smooth passage of other products in performing mechanical thrombectomy procedures. The joint can have a low-profile proximal strut formed integrally with the distal tubular section and configured to interlock with a distal portion of the guidewire so that there is a smooth transition of stiffness between the guidewire and the tubular portion of the catheter to improve trackability and decrease the likelihood of kinking. The distal tubular section of the proximal joint can also have features to tailor flexibility. The distal tubular section can be configured to push radially outward to form a seal with an outer catheter to optimize aspiration transmission to the distal mouth of the aspiration clot retrieval catheter.

Systems for the simulation of percutaneous medical procedures are disclosed. The systems can include a simulated vasculature including a first component configured to allow for introduction of a medical device into the system through an introductory port, a second component connected to the first component and shaped to simulate a portion of a human vasculature, and a third component connected to the second component and shaped to simulate a delivery site for the medical procedure. The system can be configured to allow for a medical device to be delivered to the third component by passing through the introductory port of the first component and passing through the second component. The system can be configured to replicate simulated conditions of use for the medical procedure. Methods for simulating a percutaneous medical procedure using a simulated vasculature are also disclosed.

An ultrasonic surgical instrument includes a reusable handle assembly and a removable and disposable shaft assembly. The handle assembly includes a trigger, a housing having a distal aperture formed in a distal end of the housing, and a drive member in communication with the trigger to actuate the drive member. The shaft assembly includes a proximal shaft portion, a rotator knob having a coupling feature, a transmission assembly extending distally from the proximal shaft portion, and an end effector coupled to the distal end of the transmission assembly. The drive member of the handle assembly is removably coupled to the proximal shaft portion of the shaft assembly. Another version includes a drive member of the handle assembly configured to removably engage a proximal shaft portion of the shaft assembly via a biasing member. Another version includes a waveguide of the transmission assembly non-threadably coupled to a transducer.

A surgical instrument includes a handpiece having a user input feature and a user feedback feature. A shaft assembly extends distally from the handpiece. An end effector is disposed at a distal end of the shaft assembly. The end effector includes an active feature responsive to actuation of the user input feature. The active feature is operable to operate on tissue in response to actuation of the user input feature. The user feedback feature is operable to provide feedback to the user that indicates information relating to operation of the end effector. The feedback may include haptic, visual, and/or auditory feedback.

An ultrasonic surgical instrument is provided. The ultrasonic surgical instrument includes a housing having an elongated shaft extending therefrom. The shaft has a jaw member disposed at a distal end thereof. The jaw member is movable between an open configuration and a clamping configuration and includes a tissue contacting surface thereon. A cutting blade extends from a distal end of the shaft and operably couples to the housing and adjacent the jaw member to treat tissue. A selectively removable laminate liner is positionable over the tissue contacting surface of the jaw member and configured to prevent contact between the tissue contacting surface and the cutting blade when the cutting blade is treating tissue.
摘要:
An apparatus maintains the sterility of a medical device while providing for the insertion of an insertable component into the medical device. The apparatus includes a medical device having a housing sized to contain the insertable component, an active feature, a cap, and a hinge member. A container encases the medical device within a device recess, a cap recess, and a container cover. The insertable component may be inserted into the housing while limiting potential contact with the exterior of the medical device. An alternative assembly comprises an insertion assembly having a handle and the insertable component detachably attached thereto. The medical device comprises a housing, an active feature, and a flexible member. An insertion tube is insertable within the flexible member to limit contact when the insertable component is inserted into the housing. Yet another configuration includes a resiliently hinged door assembly releasable by a release button.
