HANDHELD VACUUM DEVICE WITH CAMERA AND ILLUMINATION
20190191970 · 2019-06-27 ·

The handheld vacuum device disclosed herein comprises, at least, an air pump, a digital camera, and an illumination source. The device uses negative pressure to withdraw foreign objects from areas otherwise difficult to access and visualize, and is preferably used in removing tonsilloliths from the tonsillar crypts of a user. Negative pressure is preferred to prevent dissemination of foreign material down a user's throat and avoid causing additional trauma to the tonsillar crypts. The design disclosed herein further benefits from camera-assisted visualization and illumination to aid in removal of tonsilloliths further down a user's throat and not otherwise visible by unassisted visualization. The endoscopic camera is intended to be a commonly available design that interfaces with standard smart phone devices to display the images acquired through the camera lens.

FEATURES FOR COMMUNICATION OF FLUID THROUGH SHAFT ASSEMBLY OF ULTRASONIC SURGICAL INSTRUMENT

A surgical apparatus comprises a body, a shaft assembly, a rotation input assembly, and an end effector. The shaft assembly defines a longitudinal axis and a first fluid passageway. The rotation input assembly is operable to rotate the shaft assembly about the longitudinal axis. The rotation input assembly defines a second fluid passageway. The second fluid passageway is in fluid communication with the first fluid passageway. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade. The end effector is in fluid communication with the first fluid passageway such that the end effector is configured to receive fluid communicated through the first and second fluid passageways.

Reusable surgical retrieval apparatus with disposable cartridge assembly
10258317 · 2019-04-16 · ·

A surgical retrieval apparatus includes a tube assembly, a cartridge assembly, and a plunger assembly. The cartridge assembly is releasably engagable with the tube assembly and includes an end effector assembly disposed therein. The end effector assembly includes a specimen retrieval bag releasably coupled thereto at a distal end thereof and a first engagement member disposed at a proximal end thereof. The plunger assembly is configured for insertion through the tube assembly and into the cartridge assembly. The plunger assembly includes a second engagement member configured for releasably engaging the first engagement member. When the first and second engagement members are engaged with one another, the plunger assembly is movable between a more proximal position, wherein the end effector assembly and specimen retrieval bag are retracted within the cartridge assembly, and a more distal position, wherein the end effector assembly and specimen retrieval bag are deployed from the cartridge assembly.

Tissue litigation devices and methods therefor

Described here are closure devices and methods for ligating tissue, such as the left atrial appendage. The closure devices may comprise a snare loop assembly comprising a snare and a suture loop releasably attached thereto. The snare may be releasable from an elongate body of the closure device. In some instances, the closure device may comprise one or more markers to allow a user to determine whether the snare loop assembly is twisted.
