Abstract: A hemostatic clip includes a traction device, a clamping device and a first limiting member. The traction device includes a traction mechanism and a separation mechanism. The clamping device includes a constricting sleeve and a clip head assembly. A proximal end portions of the clip head assembly is inserted in an inner bore of the traction mechanism in an interference-fit manner. The separation mechanism prevents a second locking member of the clip head assembly from being connected to a first locking member of the constricting sleeve, thereby allowing the traction mechanism to drive, under the action of an external force, the clip head assembly to move along an axis of the constricting sleeve. The clip head assembly can be separated from the traction mechanism simply by providing an external force that can overcome the interference fit between the two.

Abstract: Microchannels in hydrogels play an essential role in enabling a smart contact lens. A wearable contact lens is disclosed herein that uses microchannels and connected chambers located in poly-2-hydroxyethyl methacrylate (poly(HEMA)) hydrogel that is used in a commercial contact lens with three-dimensional (3D) printed mold. The corresponding capillary flow behaviors in these microchannels were investigated. Different capillary flow regimes were observed in these microchannels, depending on the hydration level of the hydrogel material. In particular, it was found that a peristaltic pressure could reinstate flow in a dehydrated microchannel, indicating the motion of eye-blinking may help tear flow in a microchannel-containing contact lens. Colorimetric pH and electrochemical Na+ sensing capabilities were demonstrated in these microchannels. Micro-engineered contact lenses formed using poly(HEMA) hydrogel can be used for various biomedical applications such as eye-care and wearable biosensing.
