Abstract: A surgical saw blade has an upper surface and a lower surface, and includes a first end having right and left side edges, where the first end is configured to connect to an oscillating head of a powered saw. The saw blade also has a cutting end; and an elongated shank connecting the first end and the cutting end. The first end of the saw blade may be narrower than the shank, and a stopping surface may connect the first end to the elongated shank. The stopping surface is configured to engage the oscillating head of the powered saw, so as to ensure correct positioning of the saw blade relative to the oscillating head. The elongated shank of the saw blade may have an elongated hole through the shank, where the size and shape of the elongated hole are configured to optimize a resonant frequency and/or a dynamic stiffness of the saw blade. The cutting end of the saw blade may have a plurality of first teeth thereon, where each first tooth is mounted on a distal end of a tine.

Abstract: A surgical stapler. The surgical stapler includes a drive system, an electric motor, a battery and a control system. The electric motor is mechanically coupled to the drive system. The battery is electrically couplable to the electric motor. The control system is electrically connected to the electric motor and includes an H-bridge circuit, an electrically resistive element and an electrically inductive element. The H-bridge circuit includes a high side and a low side. The low side of the H-bridge circuit includes first and second switching devices. The electrically resistive element is electrically connected in series with the first switching device. The electrically inductive element is electrically connected to the electrically resistive element. The control system is configured to control a force applied to the drive system based on a current downstream of the electrically resistive element.

Abstract: Medical devices and related methods for transforming bone, other tissue, or other material are disclosed herein. According to an aspect, a cutting device includes a static casing that defines a sheathing slot and an opening. The sheathing slot extends to the opening and has a first height at an end of the opening. Further, the bone cutting device includes a horn including a first end and a second end. The first end is configured to operatively connect to a source of movement. Further, the second end includes a cutting component having a second height. The first height is greater than the second height.

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.
