Problems solved by technology

There are certain defects and influencing factors in this method: 1. The temperature of the nickel-titanium device rises rapidly due to ultrasonic vibration, which can cause the device to break again
2. A large amount of tooth tissue is removed, especially the separation instrument located at the apex, which will damage the root canal to a greater extent, easily causing side penetration and longitudinal fracture of the tooth
3. The rotating action of cannula technology may cause some instruments to move to the root easily, increasing the difficulty of removal

Abstract

The invention discloses a device for taking out a broken instrument in a root canal and a take-out method thereof. The device is characterized by comprising a mechanical trephine and a single-opened window sleeve, wherein the mechanical trephine is composed of a cylindrical trephine (1) and an adapter, wherein the adapter is composed of a connector (2) and a fastener (3); the cylindrical trephine (1) is connected with one end of the connector through a fastener; the other end of the connector is matched with a connector in a dentsply root canal treatment motor, so that the cylindrical trephine is arranged on the dentsply root canal treatment motor to realize rotary control on the cylindrical trephine; the single-opened window sleeve is composed of a single-opened window sleeve body (4), a wedge (5) and a clamping handle (6); and a manual trephine can be replaced with the mechanical trephine to form another set of device. According to the take-out method of the device for taking out the broken instrument in the root canal, a few of dental tissues are removed when the broken instrument in the root canal is taken out, and the device has the advantages of being simple and fast to operate.

Description

technical field [0001] The invention belongs to the field of auxiliary medical instruments, and in particular relates to a device and a method for taking out a separation instrument in a root canal. Background technique [0002] Pulp disease and periapical disease are the most common oral chronic bacterial and infectious diseases, and root canal therapy is the most effective method for treating pulp disease and periapical disease. Root canal treatment effectively reduces the microorganisms in the root canal through mechanical-chemical preparation, and through three-dimensional filling, so as to effectively promote the healing of periapical lesions. Root canal treatment, especially root canal preparation, uses a variety of instruments, such as NiTi instruments, pulp extraction needles, stainless steel files, reamers, etc., and these instruments may be separated during root canal treatment. Intra-root canal device separation is a difficult complication of root canal treatment...
