Light-guide end for hand-held curing lamp device, curing lamp system for dental and method for curing composite dental material

Abstract

The invention discloses a light-guide end for a hand-held curing lamp device. The light-guide end comprises an input end receiving light-emitting diode light from the hand-held curing lamp device, an output end transmitting the light-emitting diode light. The light-guide end also comprises a spindly flexible body and a light-guide core, wherein the light-guide core extends between the input end and the output end and has a length capable of extending the light-guide end. The light-guide core provides a light-guide wave duct. The light-guide wave duct is in photo-communication with the light input end and the light output end, and transmits the light-emitting diode light between the light input end and the light output end. The flexible body has sufficient flexibility, and therefore the flexible body can be bent to a bending shape and can be plastically deformed, and the flexible body can keep the bending shape until an operator resets the flexible body. The invention also discloses a curing lamp system for dental. The curing lamp system comprises the light-guide end and the hand-held curing lamp device with a curing light source. The invention also discloses a method for curing, in a dental surgery process, a composite dental material synthesized by light curing.

Description

technical field [0001] The present invention relates generally to medical devices and, more particularly, to a light-directing tip for a hand-held curing light instrument, a dental curing light system incorporating the light-directing tip, and a device for curing light during a dental procedure. Methods of curing composite dental materials. Background technique [0002] Composite resins are commonly used in dental applications and surgical procedures, for example as restorative materials or adhesives. Such composite resins are generally synthetic resins, which have been widely used as restorative materials because of good properties such as insolubility, easy handling, etc. "Light-curing" synthetic resins are also relatively common now. These light-curable synthetic resin-based composites are typically cured using dental curing lights. [0003] Several different types of dental curing lights exist in the prior art, all of which are used to polymerize light-curable synthet...

Problems solved by technology

[0004] Chinese patent CN2287466Y (disclosed on August 12, 1998) discloses a kind of dental curing lamp structure, and the light guide tube of this curing lamp is a kind of optical fiber light guide tube, and this light guide tube is made of optical fiber glass fiber, Very easily damaged by collision, its shape cannot be adjusted

These existing technologies have certain shortcomings. Taking LED light curing lamps as an example, they have short rigid light-guiding ends, and the lamp is located on the rigid light-guiding ends, at a suitable position

These known curing lights require dentists to elevate their hands / shoulders to uncomfortable positions in order to ensure that the curing light is irradiated precisely where it is needed, and over time, chronic muscle strain or Other undesired problems caused by the product

Therefore, the dental curing light system of prior art needs to be improved
