Removing device for root pipe obstruction

Abstract

Provided is a removing device for removing root pipe obstruction, comprising a sleeve which is internally provided with a movable groove, and a clamping member arranged inside the movable groove and capable of generating axial displacement relative to the sleeve, wherein one end of the clamping member is formed with a gripping section; the gripping section is provided with a groove hole and at least one open groove, with the open groove being connected with the groove hole; the gripping section forms a diameter-expanding taper shape; and the external diameter of the gripping section is greater than the internal diameter of the sleeve. The removing device utilizes the clamping member to take the foreign matter blocked inside the dental pulp cavity. Moreover, the clamping member can be made to stably clamp the foreign matters via the axial shifting of the sleeve and generate no loosing during the taking-out process. The removing device, with convenient operation, can rapidly remove the foreign matter and be helpful in raising the root canal therapy efficiency.

Description

technical field [0001] The invention relates to a device for removing a root canal obstruction, in particular to a device for removing a root canal obstruction that can remove foreign matter blocked in a dental pulp cavity. Background technique [0002] When early dentists performed root canal treatment on patients, they often encountered the situation that the root canal file broke in the pulp cavity, and generally needed to expand the cavity to remove foreign objects, but in this way, the tooth would be damaged in the root canal treatment. After that, it is prone to damage and cracking. [0003] For this reason, such as the U.S. No. 5879160 "Root canal obstruction removal system" patent case discloses a kind of existing root canal obstruction removal device. Please refer to figure 1 , the root canal obstruction removal tool 9 includes a hollow sleeve 91 and a piston 92, the sleeve 91 has a lumen 911, and an opening 912 is formed at one end of the sleeve 91, the sleeve 91...

AI Technical Summary

Problems solved by technology

[0007] However, during the process of taking out the foreign object, the sleeve 71 will elastically recover. At this time, although the opening 711 is still fitted outside the foreign object, it will definitely not be able to firmly hold the foreign object, so it is still possible to remove the foreign object. The problem of loosening occurs when the foreign object is not completely taken out, so the way of clamping the foreign object still needs to be improved
