Abstract
The utility model relates to a safe tooth drill of preventing from back suction. The convex end of the lower part of a tooth drill head section is provided with a tapered gas proof back suction cover. One end of the cover is tapered and the taper angle is 60 DEG; the right part of the cover is also tapered and the taper angle is 30 DEG. When the press-button is pressed to start the tooth drill, the operation of drilling can be carried out. Simultaneously, through airflow and water flow, the residue in the teeth can be washed away at any moment. The back suction cover can baffle the airflow and the liquid. The blood and the oral cavity saliva can not flow in reverse direction. The utility model is sanitary and safe, and can prevent cross infection. The utility model has simple structure and can be arranged on a tooth drill in any type.
Description
Technical field
This utility model relates to a kind of anti-resorption safety dental drill, belongs to technical field of medical.
Background technology
The oral cavity doctor uses dental drill often in the treatment odontopathy, with dental drill the moth of tooth erosion part is removed and polished whole, and then does further repairing treatment.Existing dental drill is in its therapeutic process; the situation that saliva in residue, blood and the oral cavity when air-flow, liquid stream and dental drill drilling all can be refluxed; both unhygienic; and the time regular meeting cross infection takes place; so and insalubrity can not overcome this backflow phenomenon but present dental drill all has corresponding parts.
Summary of the invention
The purpose of this utility model is that a kind of anti-resorption safety dental drill will be provided, and it can overcome above-mentioned shortcoming.Mainly be to install a gas-tight resorption cover additional,, prevent the backflow of air-flow, water liquid and blood, not only safety and sanitation but also further improved the effect of treatment in order to play shielding action at the dental drill head section.
The structure of anti-resorption safety dental drill is to locate to be equipped with a gas-tight resorption cover (3) at dental drill head (2), the left end of this resorption cover (3) tapered (26), right-hand member also tapered (27).Head (2) and head lid (5) and sealing ring (21) are housed in the head (2), are with button spring (6) on the bar of button (7); Head (4) is equipped with in the bottom of head (2); The extension (1) on head (2) right side links to each other with handle front portion (10), and the forward rear end of this handle (23) is to upper right bending shape, connects one handle rear portion (15) with screw again, has step to contact with the step of pipe joint (18) in the inner chamber at rear portion; Joint (18) front end and sealing gasket (17) adjacency connect a plinth (16) again, and a pressure ring (19) is equipped with on the step right side of joint (18); Right-hand member plug-in mounting one choma (20) at handle rear portion is equipped with water pipe valve body (11) in the inner chamber of handle rear portion (1 5), spool (12) is contained in the valve body (11), and spool (12) is gone up suit one sealed tube (13); Sealing ring (14) and end cap (23) are equipped with in valve body (11) rear end, and valve body (11) left end is tapered, plug-in mounting one water pipe (8) in the taper, and water pipe (8) leads to head (2) bottom, and an aperture (24) that tilts is arranged and lead to head (2) outside; Spool (12) inner chamber is plug-in mounting one water pipe (25) and stretch and be connected with joint (18) to the handle rear portion also; Trachea (9) is contained in handle front portion (10) and rear portion (15), and its right part stretches to joint (18), and left part leads in the head (2).
The advantage of anti-resorption safety dental drill is that chisel edge installs a gas-tight resorption cover additional, can thoroughly block the backflow that air-flow and liquid stream reach back liquid and mouth cavity liquid, can play the effect that prevents cross infection thus, not only health but also safety, also further improved the effect of treatment, and simple in structure, any type of dental drill all can install this cover additional.
