Based on the prior art, it is desirable for a person skilled in the art to provide a root extraction device that is simple in construction, safe and hygienic, and particularly suitable for anterior teeth.
Disclosure of utility model
The present utility model is directed to solving the above-mentioned problems by providing a root extraction device.
The utility model provides a tooth root taking-out device which comprises a root taking head and a handle, wherein the root taking head comprises a conical section, the height of the conical section is 10mm, the diameter of the bottom surface of the conical section is 2mm, the periphery of the conical section is provided with thread teeth, the bottom surface of the conical section is provided with a connecting screw, the handle comprises a clamping groove part and a holding part fixedly connected with the clamping groove part, the end part of the clamping groove part is provided with a thread groove corresponding to the shape of the connecting screw, the conical section is connected with the handle through the connecting screw, and the root taking head and the handle are made of 304 stainless steel.
Further, a connecting part is arranged between the bottom surface of the conical section and the connecting screw.
Furthermore, the connecting part is cuboid or hexagonal, and the root taking head is conveniently installed on the handle through the connecting part by using a spanner.
Further, the thread groove depth is 0.1-0.3 mm, which ensures that the thread teeth are properly clamped on the inner wall of the tooth root canal and obtain enough retention force, for example, too shallow a depth can cause insufficient retention force, and too deep a depth can cause insufficient strength of the thread teeth.
The utility model rotates the cone section into the root canal of the tooth root, and then continues to rotate the handle after the cone section is blocked, thereby driving the cone section to rotate, driving the tooth root to rotate, loosening the tooth root, and finally extracting the tooth root.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.
The structure of the present utility model will be described in detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 4, a tooth root extraction device comprises a root extraction head 1 and a handle 2, wherein the root extraction head 1 comprises a conical section 11, the height of the conical section 11 is 10 mm, the diameter of the bottom surface of the conical section 11 is 2 mm, the periphery of the conical section 11 is provided with a thread tooth 12, a connecting screw 13 fixedly arranged on the bottom surface of the conical section 11, the handle 2 comprises a clamping groove part 21 and a holding part 22 fixedly connected with the clamping groove part 21, the end part of the clamping groove part 21 is provided with a thread groove 211 corresponding to the shape of the connecting screw 13, and the root extraction head 1 and the handle 2 are made of 304 stainless steel.
The thread groove 211 of the handle 2 is sleeved on the connecting screw 13 for screw connection, the root taking head 1 is fixedly connected with the handle 2, the conical section 11 is rotationally screwed into a root canal of a tooth root to be blocked, the handheld holding part 22 continues to rotate, and the conical section 11 and the root canal are in a blocked state, so that the tooth root is driven to rotate, the tooth root is loosened, and finally the tooth root is pulled out, so that the tooth root extraction device is particularly suitable for taking out the front tooth root; the root is turned to loosen and be taken out, so that the root taking process is more minimally invasive, and the recovery period is shorter.
