Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The embodiment provides a wicresoft broken needle duster, as shown in fig. 1 and 2, broken needle 1 is arranged in tooth root canal 2, and this wicresoft broken needle duster includes broken needle clear head 3, linkage segment 4 and handle section 5, linkage segment 4 connect in broken needle clear head 3 with between the handle section 5, broken needle clear head 3 is provided with the internal thread that can with 1 outside screw thread phase-match ground threaded connection of broken needle for cavity pipe form and inner wall, the front end of broken needle clear head 3 is the cockscomb structure.

When the minimally invasive broken needle remover is used, firstly, the handle section 5 is held by hand, the root canal wall is polished through the saw teeth at the front end of the broken needle removing head 3 until the broken needle 1 in the tooth root canal 2 is exposed, then, the head of the broken needle 1 enters the hollow circular tube-shaped broken needle removing head 3, the handle section 5 is rotated to drive the broken needle removing head 3 to rotate, the broken needle removing head 3 is in threaded connection with the head of the broken needle 1, and furthermore, the broken needle 1 connected in the broken needle removing head 3 can be taken out by lifting the handle section 5 upwards.

In the minimally invasive broken needle remover of the embodiment, the broken needle removing head 3 is in a hollow circular tube shape, and the front end of the broken needle removing head 3 is in a sawtooth shape, so that the broken needle removing head 3 can well polish the wall of a root canal, the head of the broken needle 1 is exposed so that the broken needle removing head 3 can lock the head of the broken needle 1, and then the broken needle 1 is taken out.

Example 2

The debridement needle remover according to embodiment 1, as shown in fig. 1 and 2, the connecting section 4 and the handle section 5 are respectively cylindrical, and the diameter of the handle section 5 is larger than that of the connecting section 4;

the length of the minimally invasive broken needle cleaner is 2 cm, the diameters of the broken needle cleaner head 3 and the connecting section 4 are 1 mm, and the diameter of the handle section 5 is 2 mm.

The broken needle cleaning head 3 and the connecting section 4 are designed to be small in diameter, the broken needle cleaning head 3 is favorable for polishing the root canal wall to enter the tooth root canal 2 to expose the broken needle 1, and the handle section 5 is large in diameter and convenient for the hand to hold the broken needle to clean.

Example 3

As shown in fig. 1 and 2, the minimally invasive broken needle remover according to embodiment 2 is characterized in that an annular groove 6 for connecting with a slow-speed handset with a reverse function is formed at the tail end of the handle section 5.

The comprehensive treatment table is provided with a slow-speed mobile phone which has a reverse rotation function; when the minimally invasive broken needle remover is used, firstly, the root canal wall is polished through sawteeth at the front end of the broken needle removing head 3 until the broken needle 1 in the tooth root canal 2 is exposed, then, the head of the broken needle 1 enters the hollow tubular broken needle removing head 3, furthermore, the slow mobile phone is connected with the annular groove 6, the annular groove 6 is driven to rotate reversely through the reverse rotation function of the slow mobile phone, the reverse direction refers to the direction opposite to the external thread direction of the broken needle 1, the broken needle removing head 3, the connecting section 4 and the handle section 5 synchronously rotate reversely while the slow mobile phone drives the annular groove 6 to rotate reversely, the broken needle removing head 3 can be in threaded connection with the head of the broken needle 1 through reverse rotation, and the broken needle removing head 3 can lock the head of the broken needle 1. The annular groove 6 can be matched with a reverse function slow-speed mobile phone conveniently.

Example 4

As shown in fig. 1 and 2, the saw teeth at the front end of the broken needle remover head 3 extend along the length direction of the minimally invasive broken needle remover in embodiment 1. Therefore, the hand-held handle section 5 can quickly polish the canal wall through the saw teeth at the front end during force application to quickly expose the broken needle 1 positioned in the tooth root canal 2, and then the broken needle 1 is taken out continuously in subsequent operation.

Example 5

The minimally invasive broken needle remover according to embodiment 2 is characterized in that the broken needle removing head 3, the connecting section 4 and the handle section 5 are integrally formed;

the connecting section 4 and the handle section 5 are both solid columns. Therefore, the minimally invasive broken needle remover disclosed by the embodiment can have good firmness and durability.

Example 6

The minimally invasive broken needle remover according to embodiment 1 is characterized in that the direction of the internal thread of the broken needle removing head 3 in the shape of a hollow circular tube is opposite to the direction of the external thread of the broken needle 1. Therefore, the broken needle clearing head 3 can be well in threaded connection with the broken needle 1, and the broken needle 1 is stably locked and then taken out.

The utility model discloses the design theory of wicresoft broken needle duster is the broken needle of breaking in the root canal is taken out with minimum wound, fastest speed. Broken needle of rupture has clockwise rotation's screw line in the root canal, and broken needle clears away first 3 can be provided with the anticlockwise rotation internal thread correspondingly, and the broken head that will block the broken needle when the first 3 slow anticlockwise rotations of broken needle is clear away to the broken needle of reverse screw thread, and the screwed rotation track when the broken needle clears away first 3 entering root canals, and broken needle clears away first 3 can retreat automatically when the reverse rotation, slightly carrying again, and the broken needle will withdraw from the root canal soon. The screw thread of the broken needle clearing head 3 is locked with the screw thread of the broken needle head when rotating, so that the broken needle can be successfully cleared by the pulling force.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
