Abstract

The invention discloses a root canal flushing device with a back suction function. The device comprises a root canal flushing head and a back suction needle tube which are detachably assembled. The root canal flushing head comprises a rod-shaped body, a flushing flow channel is formed in the length direction of the rod-shaped body, the front end of the flow channel is a flushing opening, and the rear end of the flow channel is communicated with a dental flushing device. The back suction needle tube comprises a needle head part and a tube body part, and the lower end of the needle head part is a liquid suction end and extends into a root canal of teeth; the rear end of the tube body part is communicated with a dental back suction device; the front end of the root canal flushing head is bent upwards, the lower end of the needle head part is inclined forwards, and an included angle alpha is formed between the center line of the needle head part in the length direction and the center line of the rod-shaped body in the length direction; the flushing opening at the front end of the flushing flow channel is bent downwards, and an included angle beta is formed between the center line of the cross section of the flushing opening and the center line of the needle part in the length direction. The invention provides a safer, cost-effective method to continuously deliver irrigation fluid without tip pressure while safely evacuating is performed by negative pressure.

Description

technical field [0001] The invention relates to a dental medical instrument, in particular to a root canal irrigation device with a suck-back function used for cleaning the root canal during dental pulp treatment. Background technique [0002] Endodontics aims to mechanically and chemically remove microorganisms from the root canal, inactivate their by-products and perfectly seal the root canal space to prevent future recontamination of the root canal space. If the root canal can be thoroughly cleaned and then effectively sealed using irrigation alone, mechanical instruments are unnecessary. [0003] The initial cleaning of the root canal is usually performed with mechanical instruments to remove most of the pulp tissue, necrotic debris and bacterial biofilm or previous root filling material. No further cleaning is possible without removing the old material in the aforementioned root. Mechanical instruments use stainless steel hand files or motor-driven nickel-titanium (Ni...
