Dental handpiece

Abstract

The invention relates to oral cavity medical instruments and relates to a dental handpiece. The dental handpiece comprises a handpiece head, a dental bar is arranged on the lower portion of the handpiece head, a safety sleeve is arranged outside the dental bar and connected with the handpiece head, and the lower end of the dental bar extends from the safety sleeve. By additionally arranging the safety sleeve outside the handpiece head, safety performance of the dental handpiece can be improved, and accidental injuries during operation can be prevented; since safety sleeves different in diameter and length are adopted to match with the lower portion of the handpiece head, drilling depth can be controlled effectively, a preset scheme for operative treatment can be guaranteed effectively, and treating effect can be ensured; the safety sleeve can be used to cooperate with a plantation guide plate, so that the position, the angle and the depth of a drilled hole for plantation during planting operation can be ensured, and operation effect can be ensured maximally.

Description

Technical field [0001] The invention relates to oral medical equipment, in particular to a dental handpiece. Background technique [0002] The dental handpiece is a commonly used dental medical device. Through high-speed rotation and different shapes of burs, it can locate, drill, expand or even cut the oral hard tissues. At present, the commonly used dental handpiece (see figure 1 ), including the handle 1, the mobile phone head 2 located at one end of the handle, and the bur 3 located outside the head 2 and connected to the mobile phone head 2 through the chuck (external accessories, different shape lengths need to be used together); but because of the dental mobile phone car Needle 3 When an existing doctor drills a patient during implant surgery, it is difficult to grasp the depth of the drill, which is entirely dependent on the doctor’s experience; for example, the doctor needs to drill down 10 mm of the patient’s teeth, but During the drilling process, the doctor can only j...

[0002] Dental handpiece is a commonly used dental medical device. Through high-speed rotation and different shapes of burs, it can position, drill, expand or even cut oral hard tissues. Currently, the commonly used dental handpiece (see figure 1 ), including the handle 1, the handpiece head 2 located at one end of the handle, and the bur 3 located outside the handpiece 2 and connected to the handpiece 2 through the clip (external accessories, different shapes and lengths need to be used together); but because the dental handpiece Needle 3 When existing doctors drill holes in patients during implant surgery, it is difficult to grasp the drilling depth, which depends entirely on the doctor's experience; During the drilling process, the doctor can only judge how deep the drill is based on the scale on the bur 3, personal feeling, and experience. It may only be 8mm, but the doctor thinks that the predetermined 10mm has been reached, because usually the bur Needle 3 has multiple scales in order to drill implant holes of different depths. It is easy to make mistakes due to poor vision during the operation, and even drill deeper than expected, which will damage the neural tube or maxillary sinus, making the operation unsatisfactory. to guarantee
