Abstract: This disclosure may disclose, inter alia, a handle for actuating a device. The handle may include a top comprising a first end and a second end, a first top side coupled to the first end of the top via a first corner hinge, and a second top side coupled to the second end of the top via a second corner hinge. The handle may further include a first bottom side coupled to the first top side via a first side hinge, a second bottom side coupled to the second top side via a second side hinge, and a bottom coupled to the first bottom side via a third corner hinge and coupled to the second bottom side via a fourth corner hinge. In some examples, actuation of the handle may cause deployment or retraction of an element from or into a shaft.

Abstract: This disclosure may disclose, inter alia, devices, systems, and methods for cleaning or removing contamination from a lens, or for increasing visibility of a lens during surgery. For example, a device with a handle actuated element is disclosed. The device includes a shaft that includes a rod, an element coupled to a distal tip of the rod, and a handle coupled to a proximal end of the rod. Actuation of the handle into a first position may cause the handle to be configured in a substantially hexagonal shape and may cause deployment of the element from the shaft. Actuation of the handle into a second position may cause the handle to be configured in a substantially rectangular shape and may cause retraction of the element into the shaft. The device may be introduced into an abdomen, and an element on the device can be deployed during surgery.

Abstract: A surgical instrument for applying purse string sutures to tissue is provided that includes two circular discs that each have notches within a perimeter of the disc for receiving tissue and through which a suture wire may pass. The device also includes push plates for advancing the suture wires through the notches of the two circular discs and into portions of the tissue. Suture is placed within each push plate and is connected to ends of the suture wires. Suction is applied to the circular discs through a shaft to draw the tissue into the respective notches of the circular discs so that the suture wires may be advanced through the tissue and the sutures can then be pulled through the tissue to create two purse-string sutures.
