Abstract

The invention concerns a security device comprising a stop member for a rotary drilling instrument used in particular in dental surgery, said stop member capable of being positioned at a desired depth of drilling and preventing said depth from being exceeded. The two elements drilling instrument (10, 10A) and the stop member (20; 30; 20A; 30A) comprise coupling means directly or indirectly linking them together and co-operating means capable of transforming their movement, such that when the device is operating, the drilling instrument (10, 10A) is retracted rearwards relative to the drilling direction and to the position of the stop member under the action of said means when the front part (23; 33; 23A; 33A) of the stop member comes in contact with a neighbouring surface (9). The co-operating means preferably consist of a screw-nut system, the direction of the thread(s) of said system and the rotating direction of the drill being opposite. A device comprising a gauge (50) containing a piston (55) enables to pre-calibrate and store the desired drilling depth.

Description

Technical field

[0001] The present invention relates to a safety device with a stopper described in the preamble of independent claim 1, especially for dental surgical drilling instruments. The present invention also relates to a pre-calibration and storage device for the drilling depth described in the preceding section, which is an advantageous method for using the safety device.

[0002] One preferred application of these devices is for dental implants. Background technique

[0003] As we all know, when performing certain operations, especially for the treatment of root canal diseases, certain tooth injuries, hard tissue diseases of the teeth or jaws, such as implanting dental implants, a special device must be used ( Dental medical therapy equipment, dental drills, implantation drilling instruments, etc.) drill holes according to the determined depth, and the drill depth is determined by the doctor according to the specific conditions of the patient.

[0004] The above depth ...
