Abstract: Mechanical keypads are disclosed. According to one embodiment, a mechanical keypad may include a key cap comprising a post extending from a bottom surface thereof; a structural element comprising a passage configured to receive the post therethrough; and a key securing device that securely receives, through the passage, the post in a recess or opening formed therein, and comprising a key switch interface on a lower surface thereof. The key cap and the key securing device may move substantially in unison when the key post is securely received in the key securing device.

Abstract: A bipolar electrosurgical forceps device having a handle at the proximal end and forceps jaws at the distal end is described. These two ends are connected via an elongated tubular section that houses the actuating member for controlling the motion of the forceps at the distal end relative to the motion of the proximal handle. A dovetail member connects the forceps to a shaft that is slidably disposed in the tubular section at the distal end of the device, where the tubular section constrains the motion of the two jaws perpendicular relative to the axial direction. A coupling member is attached to the actuating member where drive slots interact with the drive pins on the forceps, whereby squeezing the handle causes the desired relative parallel opening or closing motion of the forceps jaws.
