Vascular clamp structure

InactiveUS20110313437A1Improved vascular clamp structureIncrease shear forceSurgical staplesWound clampsEngineeringBlood vessel
An improved vascular clamp structure is comprised of a clip body and two clipping pieces, all of which constitute a vascular clamp used cooperatively for medical clamping pliers. The clip body is arranged with a bridge part, and from two ends of which a clipping part extends respectively and making one side of the clip body forming an opening; the clipping piece is arranged with a clipping body with a fitting slot. The fitting slot and the clipping part can be assembled together. Both adjacent faces of the clipping bodies are respectively arranged with a groove and at least one male or female fastener inter-buckled together. Wherein, the clip body is set as a memory metal. By arranging clipping pieces, the vascular clamp of the present invention enhances the frictional areas of inter-contact. Arranging male and female fasteners at the adjacent faces of clipping pieces also enhances the clipping force, and effectively improves the slipping drawback of traditional vascular clamp. In addition, the vascular clamp is made of memory metal; by the separation of male and female fasteners, the vascular clamp further possesses the function of dismantlement.

Protective head covering having impact absorbing crumple zone

InactiveUS6996856B2Closer in weight and sizeMinimizing resultant disproportionHatsSport apparatusMostly TrueEngineering
A helmet construction for protecting a user's head, and the brain within the cranium from impact forces, includes a shell contoured to the shape of the user's head, with cushioning along at least part of the shell interior and a chinstrap. The shell consists of three (or more) discrete panels that are physically and firmly coupled together providing rigid protection under most circumstances, but upon impact the panels move relative to one another, but not relative to the user's head, thereby permitting impact forces to be dissipated and / or redirected away from the cranium and brain within. Upon impact to the helmet, there are sequential stages of movement of the panels relative to each other, these movements initially being recoverable, but with sufficient vector forces the helmet undergoes structural changes in a pre-determined fashion, so that the recoverable and permanent movements cumulatively provide a protective ‘crumple zone’ or ‘shear zone’. The first two stages of protection arise from the design of the fasteners that have the ability to invaginate and collapse within themselves, and their design having a 45 degree angle, which will allow movement of a region of connected panels to translate along the fastener shaft. Both of these movements will be recoverable and provide a ‘functional crumple zone’. The final stage of protection arises from the braking function of the pins, as they are forced from one aperture through to the next, the direction and extent of which is determined by the impact force and direction. This final level of panel movement and protection is not recoverable and thus provides a ‘structural crumple zone’. Finally the fastener size and thickness, together with the thickness of webbing and distance between apertures, functions to provide varying degrees of resistance to impact forces, thus making the helmet design suitable for activities with different levels of impact speed and risk potential.

Reduced shock breakaway set screw for use with a surgical construct

A reduced shock breakaway set screw for use with medical implants and constructs for the spine having improved geometry of the groove area between the upper head portion and lower threaded portion of the set screw. The groove area of the set screw has circular and noncircular portions which in at least one embodiment comprise upper and lower radii separated by a flattened groove bottom. Other embodiments have apertures running between the groove area and an internal cylindrical bore and / or ridges or ribs running across the groove area. The improved geometry serves to slow down the fracturing process during shearing thereby increasing the proportion of energy dissipated as heat from plastic deformation of the material to the amount of energy released as kinetic energy from elastic deformation, thus reducing shock to the patient and physician without changing the preset break-off torque for the set screw.
