Abstract

The embodiment of the invention provides a dental handpiece, a handpiece head thereof, and a root canal preparation machine, and relates to the technical field of medical instruments. The handpiece head of the dental handpiece comprises a handpiece head shell, wherein a machine core cavity is formed in the handpiece head shell; a rotatable machine core and a driving gear are arranged in the machine core cavity; the driving gear is in sleeving to one end of the machine core; the machine core can move along the axial direction of the driving gear; and a reciprocating driving mechanism is further arranged in the machine core cavity and is used for driving the machine core to carry out reciprocating motion along the axial direction of the machine core. Therefore, when the dental handpiece disclosed by the embodiment of the invention is used for carrying out root canal treatment, a root canal file is driven by the reciprocating driving mechanism to carry out the reciprocating motion along the axial direction of the root canal file, manual lifting is not required, so that the treatment efficiency of root canal expansion is improved, the requirement of a patient for the cavity space is lowered, the operation of root canal expansion treatment can be conveniently carried out, and the treatment experience of the patient is improved.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a dental handpiece, a handpiece thereof, and a root canal preparation machine. Background technique

[0002] Oral root canal treatment includes root canal length measurement, root canal enlargement, and then root canal filling; in the process of tooth root canal enlargement operation, it is necessary to use a root canal preparation machine to enlarge the damaged or blocked tooth root canal. The root canal enlargement method is to clamp the root canal file on the contra-angle handpiece of the root canal preparation machine, and then use the contra-angle handpiece to dredge and expand the root canal.

[0003] The inventors have found that because the existing contra-angle handpiece movement is driven by the drive shaft to rotate, it is necessary to repeatedly lift the contra-angle handpiece during root canal enlargement treatment, and the operation efficiency is low; an...
