A surgical device based on the concept of controlling the laser power during laser surgery based on optical and other signals from the tip and the tissue is described. A laser surgical system generally comprises several basic components, such as a laser, a delivery system, a tip and a control system. A tip may be considered as a particular case of a thermo-optical tip (TOT). TOT is an optical and mechanical element which could be used to modify or treat soft and hard tissues, including cutting, coagulation, vaporization, carbonization, and ablation of tissues.

Disclosed herein is an improved dental operatory lamp having an LED light source that directs light to a reflector that in turn reflects the light to illuminate a treatment area. In one embodiment, the lamp is adapted for efficient transfer of heat from the light source and into the environment. In another embodiment, the lamp is adapted to generate a predetermined pattern of light optimal for the treatment area. In other embodiments, the lamp includes structural features that enable the lamp to maintain optimum light intensity and/or temperature. Also, disclosed herein are unique reflector embodiments that intentionally provide a generally smooth surface, without facets, that reflect light at all visible and infrared wavelengths.

An improved dental scalpel includes a coupling device, a handle comprising an opening in the coupling portion of the handle including an inner thread along handle main axis, and a blade portion comprising a blade holder including the coupling portion at the handle side of the blade holder and a blade on another side of the blade holder.

The invention relates to a medical instrument used for a dental operation, in particular to a mandibular condyle reposition expander. The mandibular condyle reposition expander comprises a lower supporting and combining portion and an upper supporting and combining portion. The lower supporting and combining portion corresponds to the incisura of the underjaw of the human body. The upper supporting and combining portion is matched with the zygomatic arch corresponding to the incisura of the underjaw of the human body. A lower supporting front rod and a lower supporting rear rod are hinged to the two ends of the lower supporting and combining portion respectively. An upper supporting front rod and an upper supporting rear rod are hinged to the two ends of the upper supporting and combining portion respectively. The upper end of the lower supporting front rod and the lower end of the upper supporting front rod are hinged to a front hinged shaft. The upper end of the lower supporting rear rod and the lower end of the upper supporting rear rod are hinged to a rear hinged shaft. Both the front hinged shaft and the rear hinged shaft are arranged on a middle shaft. The expander is compact in structure and convenient to use, the pains of patients are small, force is reasonably borne, mechanical deformation or breakage can not easily occur in the use process, and the mandibular condyle reposition expander can adapt to different individual differences.

A dental tray having a planar portion and a single wall, useful for dental treatments including bleaching, fluoride applications, desensitizing teeth, antibacterial treatments and other dental operations. At least one groove or bead, either continuous or segmented, divides the planar portion into a first planar portion and a second foldable portion inside the tray that can be raised by the patient to form an inner wall after the tray has been inserted into the patient's mouth. The tray is formed from any dental tray material. Preferred are copolymer formed from ethylene and vinyl acetate having a forming temperature between 125° F. and 135° F. and a freezing point between about 80° F. and 106° F.

The invention provides a formulated beverage composition that can be administered to a patient, prior to anesthesia, sedation and/or surgical or dental operation, to reduce the risk of aspiration pneumonia while simultaneously improving the well-being of the patient. The beverage composition is designed to be taken orally, by a patient, within a specified short period of time prior to administration of an anesthesia and/or sedative/analgesic. Further described herein is the method of using the beverage composition. The method may include providing a written label of instructions affixed to the beverage container which instructions positively direct the patient's ingestion of the beverage composition.

A composition for local anesthesia which comprises a local anesthetic such as lidocaine hydrochloride as an active ingredient and an agent for sustaining anesthetic action selected from the group consisting of antihistamines such as diphenhydramine hydrochloride or hydroxyzine hydrochloride, and does not substantially contain catecholamines such as epinephrine, which has increased durability of anesthetic action without using catecholamines, and is useful as a safe composition for local anesthesia for performing short-time dental operations such as tooth extraction or oral surgery operations.

The invention discloses an oral Chinese medical preparation for treating acute periodontitis. The preparation is prepared from the following raw material herbs in parts by weight: 10-20 parts of white peony, 10-20 parts of indigo, 10-20 parts of root of red-rooted salvia, 10-20 parts of drynaria rhizome, 10-20 parts of pseudo-ginseng, 10-20 parts of radix angelicae formosanae, 10-20 parts of evodia rutaecarpa, 10-20 parts of dried rehamnnia root, 10-20 parts of honeysuckle, 10-20 parts of dandelion, 10-20 parts of scutellaria baicalensis, 10-20 parts of rheum officinale, 10-20 parts of borneol, 10-20 parts of fructus forsythiae, 10-20 parts of cordate houttuynia and 10-20 parts of catechu. By utilizing different Chinese medical characteristics, the invention researches the Chinese medical preparation which can clear away heat, detoxify, reduce swelling, alleviate pain, remove necrotic tissue, promote granulation and stop bleeding with astringents and has a favorable curative effect on acute periodontitis. The oral Chinese medical preparation for treating acute periodontitis has the maximum advantage of rapidly alleviating pain, can take an auxiliary curative effect on patients subjected to dental operations, and can clear away heat, detoxify, reduce swelling and alleviate pain.

An inline filter assembly to be used in conjunction with surgical or other procedures, near the patient or chairside in dental operations, that is capable of removing, by filtration, particulate matter from waste-water. The filter assembly is configured to permit easy and rapid changing of filters. The filter assembly also contains a series of stopcocks to permit easy and quick changing of filters while maintaining suction to the patient.

The invention discloses a dental operation instrument cleaning device which comprises a heating device base, a heating device and the like. The dental operation instrument cleaning device is reasonable and simple in structure, low in production cost and convenient to mount. By arranging a stirring device, a disinfectant and water are sufficiently stirred, and the situation that the disinfection effect is not ideal due to uneven stirring is prevented. By arranging an activated carbon adsorption filtering nozzle, impurities in the clear water and the disinfectant can be effectively filtered, andcleanliness inside the device is kept while pipeline blocking is prevented. By arranging an electric heater, the disinfectant is evaporated, thus a cleaning barrel does not need to be disinfected frequently, and the burdens of medical care personnel are relieved. By arranging an up-down lead screw and a left-right lead screw, moving is achieved, only the cleaning water needs to be moved into a designed position, then a filtering barrel stored with a dental instrument is moved downwards to be soaked in the cleaning water, then a second motor drives the heating device to rotate, and thus cleaning can be effectively conducted.

The present invention discloses a method of employing ion channel active compounds to deliver metabolism-enhancing molecules within the cell to promote rapid wound healing. It also develops a delivery kit for meperidine as a local anesthetic and wound healing accelerant for dental surgical use. And meperidine thus serves as a pattern for future design of novel wound healing compounds.
