Embodiment Construction

[0089] The following is a further description of the disposable turbo dental drill handpiece in conjunction with the accompanying drawings.

[0090] Disposable turbine dental drill handpiece, mainly composed of plastic injection molded handle 1, machine head 2, and air-water quick-plug connector 3, wherein the machine head 3 is equipped with a turbine shaft 4, a turbine 5 and bearings set at both ends of the turbine 6. The main air pipe 37, auxiliary air pipe 38, and water pipe 39 are internally connected to the machine head 2 from the air-water quick-plug joint 3 through the handle 1. The return air pipe is generally vacant according to the application practice, and the return air passes through the handle and the air-water quick-plug The joint is drained, especially between the bearings 6 of the turbine 5 and both sides of the suit, a wind-blocking disc 7 is respectively established.

[0091] The structure of the machine head 2 is composed of a main casing 8 formed by plasti...

Abstract

The invention discloses a disposable turbine dental drill hand machine which comprises a plastic molded handle, a machine head, an aqueous vapour quick bayonet joint, a main air duct, an auxiliary air duct and a water pipe, wherein a plastic turbine shaft, a turbine and bearings sleeved at both ends of the turbine are arranged in the machine head, and a wind-resistant round cushion is arranged between the turbine and either bearing sleeved at one end of the turbine; the output end of the plastic turbine shaft is a machine needle jack, and an internal spline is arranged in the plastic turbine shaft. The invention has simple structure, reliable performance and low manufacture cost and can truly realize the disposable aim.

Description

technical field [0001] The invention relates to a turbo dental drill handpiece, in particular to a disposable turbo dental drill handpiece and a special bur loading and unloading tool for the disposable turbo dental drill handpiece. Background technique [0002] The high-speed turbine dental drill heads used by dentists are collectively referred to as mobile phones. They are necessary equipment for dental disease treatment and tooth restoration. They are used very frequently. They use compressed air as the power source to drive the turbine in the dental drill handpiece The high-speed rotation of 200,000 to 400,000 revolutions per minute drives the bur (drilling tool) fixed in the turbine shaft to drill and grind the teeth to treat and repair dental diseases. [0003] When the doctor uses the turbo dental handpiece to drill and grind the teeth, it will inevitably contact the patient's pulp cavity, gums and oral mucosa, which often causes bleeding. If the doctor shares a dent...
