摘要:
A suture pulley assembly includes a pulley wheel that is rotatably attached to an adjustable tension applicator used in joint repair surgery (e.g., to repair an ACL) so as to equalize the tensile load that is applied to each side of a looped suture by the adjustable tension applicator. The pulley wheel includes a pair of pulley plates that define a pulley space therebetween into which a looped suture is placed and that are oppositely-biased in order to spread apart and contract in response to differences in size of the looped suture as a result of, e.g., the existence of a knot or half knot. The pulley wheel is rotatably attached to the tension applicator by a post. A spring biases one of the suture pulley plates toward the other in a manner that allows for the aforementioned expansion of the pulley space.
摘要:
A method for dissolving cellulose in which the cellulose based raw material is admixed with a mixture of a dipolar aprotic intercrystalline swelling agent and an ionic liquid at a temperature of 25° C. to 180° C. for a time sufficient to dissolve the cellulose based raw material. The molar ratio of dipolar aprotic intercrystalline swelling agent to ionic liquid is 0.05 to 1.5 moles of dipolar aprotic intercrystalline swelling agent to 1 mole of ionic liquid. Dipolar aprotic intercrystalline swelling agents do not include imidazole based agents or amine based agents.
摘要:
A cellulose pulp particle having the shape of a general prismatoid having two parallel bases, the pulp particle comprising pulp fibers in a wet laid pulp sheet form, one of the bases having an area that is equal to or greater than the area of the other base, the area of the larger base being equal to or less than 35 mm2 and equal to or greater than 8 mm2, the distance between the bases being equal to or greater than 0.9 mm and equal to or less than 5 mm, the particle being treated with a material. In some embodiments the material can be a hydrophilic, hydrophobic or softening chemical or a film.

A method of color printing is described in which only two transparent inks are used to reproduce a source image. The original digitally encoded image in red, green and blue colors may be initially adjusted for contrast, brightness, color balance, and tonal value. This is then converted to cyan, magenta and yellow encoding. The two of these channels which best represent the dominant colors of original image are then selected. The critical colors of the original image to be reproduced with reasonable accuracy are determined and spot colors that best represent these are selected from an ink palette. The spot colors are assigned to the selected channels to which they have the closest color relationship. These two channels are next superimposed to form a composite image and their greyscale values are adjusted to produce an image most closely resembling the desired final image.
摘要:
Cellulose pulp sheets treated with sodium sulfate can be fiberized to produce sodium sulfate treated fibers that exhibit desirable densification properties. The sodium sulfate treated fibers densify to a greater degree than fibers that have not been treated with sodium sulfate.

Whitened fluff pulp and methods for making whitened fluff pulp. The whitened pulp is a fluff pulp that has been treated with one or more of a white pigment, a colorant, or a fluorescent whitening agent.
摘要:
Suture separation and organization devices for use in a tissue graft tensioning system. The inventive devices help to separate and organize a plurality of suture strands that extend away from a bone tunnel of a patient's leg during joint repair surgery (e.g., while repairing or replacing the anterior cruciate ligament (“ACL”)). The suture separation and organization device may comprise one or more elongate bodies, or a one-piece body, comprising a plurality of suture retention recesses or protrusions disposed on a perimeter of a body. The suture separation and organization device also includes recesses or passages adapted to receive corresponding posts of a graft tensioning device. In this way, the suture separation and organization device can be removably attached to the graft tensioning device.
摘要:
Cellulose pulp sheets treated with a saccharide yield less than 20 wt. % knots when fiberized under standard Kamas conditions. The fiberized sheets when airlaid produce fiber webs that exhibit desirable densification properties and softness properties.
摘要:
The present invention provides a polymer derived from a cellulosic, lignocellulosic, or polysaccharide material having superabsorbent properties. Methods for making the polymer and personal care absorbent products that incorporated the polymer are also provided.
摘要:
A web of fibers is bound together by a bonding medium that has been activated by partially solubilizing the bonding medium with a solvent therefor. The fibers are insoluble in the bonding medium. As the bonding medium is partially solubilized, it becomes tacky and flows into contact with the fibers and with itself Thereafter, the solvent is absorbed by the bonding medium, allowing the bonding medium to resolidify and bond the fibers in a matrix, increasing the web strength.
