Description

Disposable tooth cutting hydrodynamic tool bit

Technical Field

The utility model relates to a disposable tooth cutting hydrodynamic tool bit, and belongs to the technical field of medical appliances.

Background

Most wisdom teeth have no effect in the mouth, and once inflamed, or grow laterally, affect their adjacent molars, affecting human health. Thus, once wisdom teeth become inflamed or laterally grown and affect adjacent molars, extraction is often required clinically. However, since the front end of the tooth is adjacent to the molar and the root is adjacent to the nerve, it is often necessary to cut the tooth therefrom and then to extract the tooth a plurality of times. Currently, wisdom teeth are cut off mainly by a hammer cutting method, an electric drill grinding method, an ultrasonic knife cutting method and the like. The hammer breaking method mainly relies on the awl to aim at the wisdom tooth breaking part, then the awl is hit with a hammer, and the teeth are broken with brute force, so that the whole gum is easy to vibrate, and the damage is large. The electric drill breaking method relies on the electric drill to break the wisdom teeth into a gap layer by layer, and then the wisdom teeth broken ends are pulled out one by one. The ultrasonic knife cuts off the middle part of wisdom teeth by means of ultrasonic waves, and then pulls out wisdom tooth broken ends one by one. Electric drill breaking and ultrasonic blade cutting are expensive and time consuming.

The medical water jet knife is a device for cold cutting by utilizing high-pressure water jet, the pressure of the medical water jet knife is far lower than that of the industrial water jet knife, but the working principle of the medical water jet knife is similar to that of the industrial water jet knife, namely sterile physiological saline is pumped out by adopting a high-pressure pump, reaches an operating handle through a catheter, and is sprayed out through a tiny nozzle on the handle to generate local high pressure so as to cut human tissues. The medical water knife has the greatest characteristics that tissue structures with different intensities and toughness are selectively cut and finely separated, so that specific tissues are protected to the greatest extent, and the medical water knife has the advantages of clear visual field and small bleeding amount, and meanwhile, as the water knife does not generate heat energy, the heat damage of other surgical instruments such as high-frequency electric knives, lasers, ultrasonic knives and the like to surrounding tissues is avoided. In recent years, the medical water jet scalpel is widely applied to clinical specialized departments such as hepatobiliary surgery, neurosurgery, rectal surgery, otorhinolaryngological head and neck surgery and the like and laparoscopic surgery by virtue of unique advantages. The water jet knife utilizes the tissue separation effect of high-pressure high-speed water jet flow and Venturi effect (vacuum effect is formed near the high-speed water flow/air flow) to remove necrotic infection tissue or human tissue, integrates the excision and irrigation processes into a whole, is gradually applied to clinic at present, but is not applied to the field of cutting teeth.
