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： An electrosurgical device having an electrode and an insulating piece such as a ceramic insulator is disclosed. The electrode includes an active surface for ablating and/or coagulating tissue in an electrosurgical procedure. The insulating piece surrounds the active surface and provides a barrier for the intense heat created during ablation. The insulating piece is also electrically nonconductive to prevent unwanted discharge of energy. Electrode has a retaining ledge configured to engage a lip formed on the insulating ring. The insulating ring is secured to the electrosurgical device by connecting the electrode to an electrode seat and capturing the insulating piece in between. The electrode can be connected to the electrode seat by projection welding. The insulating piece is connected to the electrode without the use of an adhesive.

摘要： Electrosurgical devices for ablating tissue and methods of making the same are disclosed. The electrosurgical devices include an electrode with a lumen for aspirating gasses and debris produced during surgery. The electrode also includes a plurality of upper active edges for ablating tissue in an electrosurgical procedure. The upper active electrodes are spaced apart to form a filter that filters out large tissue particles from being aspirated into the lumen. The upper active edges ablate the large particles to form particles that can pass into the lumen. A lower active edge is formed at the terminal end of the lumen for ablating tissue being aspirated into the lumen. The lower active edge prevent tissue particles from occluding the opening to the lumen.
