Detailed Description

The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 3.

Embodiment one, combine fig. 1-3, a hand is with two angle breast root canal file, including handle 1, handle 1 adopts high temperature and high pressure resistant disinfection plastics material to make, handle 1 length is 155mm to 160mm, the diameter is between 6mm to 10mm, for traditional root canal file, this length and diameter are easily held and use by hand, conveniently stretch into patient's oral cavity, be convenient for develop the treatment activity in patient's oral cavity, two non slipping spur 5 are connected with at interval screw thread on handle 1, two non slipping spur 5 account for the quarter to the third of handle 1 total length respectively, be smooth bare pole between two non slipping spur 5, handle 1 both ends are detachable respectively and are connected with first file pole 2 and second file pole 3, its concrete connected mode is, the position that handle 1 connects two file poles sets up to the structure that can gather together, and the screw thread that cooperates with non slipping spur 5 has been seted up here, after putting into handle 1 with two file poles, can squeeze the structure department that gathers together on the handle 1 through twisting two non slipping spur 5, thereby make and insert first file pole 2 and second file pole 3 inside it respectively by two non slipping spur 5 locks, promptly after putting into handle 1 junction with first file pole 2 and second file pole 3, rotate two non slipping spur 5 respectively, the part that first file pole 2 and second file pole 3 were placed to handle 1 will be pressed from both sides tightly, and it is predetermined, can set up the rubber slipmat at the both ends of handle 1 two file poles of locking, the intensity of two file poles of reinforcing handle 1 locking, first file pole 2 is the elbow shape, and second file pole 3 is two elbow shapes, the both sides towards handle 1 of first file pole 2 and second file pole 3, and the work sword of first file pole 2 and second file pole 3 has different bending angle, the bending angle alpha of first file pole 2 is 60 to 80 degrees, the first bending angle alpha of the second file rod 3 is 40 degrees to 50 degrees, the second bending angle beta is 100 degrees to 120 degrees, the selected angle is more suitable for the direction of different root canals of the tooth, the root canal direction of the tooth can be roughly divided into a near middle direction and a far middle direction, the working section is designed into the two angles, the tooth can smoothly and portably enter the root canal, the problem that other root canal preparation instruments are difficult to enter because of different root canal directions is solved, the blade parts of the working blades 4 of the first file rod 2 and the second file rod 3 are in a K-shaped file shape, the root canal preparation of deciduous teeth is mainly characterized in cleaning but not forming, the K file is flexible, is not easy to break, is easy to enter and clean the root canal, and protects the root canal wall from being cut transitionally, the working blade 4 of the first file rod 2 and the working blade 4 of the second file rod 3 are both made of stainless steel or nickel-titanium alloy, the K-shaped file working edge 4 made of stainless steel is harder than the K-shaped file working edge 4 made of nickel-titanium alloy, the toughness of the K-shaped file without nickel-titanium alloy is good, in the embodiment, the length of the second file rod 3 is longer than that of the first file rod 2, the angle of the second file rod 3 is more bent than that of the first file rod 2, the root canal of a deciduous tooth is more branched in practical use, when a deeper tooth root needs to be treated, the first file rod 2 may not conveniently enter the root canal of the deciduous tooth, the second file rod 3 can be used in a switching mode, the second file rod 3 is elbow-shaped, and the tooth canal can more conveniently enter the root canal, so that the utility model can be suitable for treating most of the root canals of the deciduous tooth, the lengths of the working edges 4 on the first file rod 2 and the second file rod 3 are both 13mm, the length of the working edge 4 selected in the embodiment is determined according to the root length range of the deciduous tooth of a human body between 5.4mm and 13mm, the blade part design of 13mm can meet the requirement of most of deciduous tooth root canal treatment.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
