Abstract: The present disclosure provides devices and methods for insufflating abdomens of subjects under direct visualization. Such devices and methods, in some implementations, include features for cleaning the devices, and certain implementations of the methods permit procedures wherein it is not necessary to use a typical obturator to place a cannula, resulting in safer procedures.

Abstract: An electronic knife assembly and associated systems and methods are disclosed herein. In some embodiments, the knife includes a blade and a handle operably couplable to the blade. The handle can include an oscillator operably coupled to the blade, at least one sensor configured to obtain one or more measurements, and a controller operably coupled to the oscillator and the least one sensor. The measurements from the sensor can include a spatial position of the electronic knife, a spatial orientation of the electronic knife, a mass of a user's hand, a grip of the user's hand, and/or a resistance to the oscillation of the blade. The controller can adjust an operating frequency of the oscillator based at least partially on the one or more measurements from the at least one sensor. The handle can also include a wireless power supply.
