Appl. No.:

12/428239

Abstract:

Casper pins have a single uniform length and are inserted to different depths into vertebrae using different depth insertion tools. The Casper pins have a sharp threaded tip and a drive head at the opposite end. The Casper pins are used with insertion tools that are each marked with a different insertion depth. The insertion tools each have a tubular front section and a driver within the tubular section and a handle for rotating the insertion tool. Once the proper insertion depth is determined, the Casper pin is placed into the corresponding insertion tool. Using the insertion tool, the tip of the Casper pin bores into the vertebra and when the designated insertion depth is reached, the driver of the insertion tool is separated from the driver head of the Casper pin. Thus, the Casper pin cannot be inserted beyond the designated insertion depth of the insertion tool. The process is repeated for the adjacent vertebrae so that two Casper pins extend from the patient. A distractor is used to separate the vertebrae so the surgeon can operate on the disc. Once the disc operation is completed, the distractor is removed and a plate is placed over the Casper pins and moved against the vertebrae. The Casper pins are replaced with screws to hold the plate in place against the vertebrae. With the plate in secured in place, the incision cut into the patient can be closed so the spine is allowed to heal.

US Classification:

239308, 239310

Abstract:

A sprayer for forming and spraying a dispersion of a dispersible substance from a cartridge and a liquid dispersion medium from a source. The sprayer has a first passageway comprising a pump, wherein the first passageway is configured for supplying at least the liquid dispersion medium from the source in response to operation of the pump; a receptacle for removably receiving the cartridge; and a second passageway in fluid communication with both the receptacle and the first passageway for supplying the dispersible substance from the cartridge to the first passageway and, thereby, forming the dispersion in response to operation of the pump. A discharge apparatus is in fluid communication with the first passageway for dispensing the dispersion from the sprayer.

US Classification:

Abstract:

An article treatment system which provides improved solution mixing and concentration uniformity. The treatment system includes a container, a closure and a channel for guiding fluid flow. The treatment system is especially advantageous for use with effervescent tablets and for use in treating contact lenses. Cleaning and disinfecting of articles is improved by use of a tubular channel which guides upwardly gas and other components released from an effervescent tablet which is located at the bottom of the treatment container. The upward central flow through the channel induces a downward flow between the container walls, the exterior walls of the channel, and the article-retaining means and towards the bottom of the container.
