Removing device for root canal 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 present invention relates to a root canal obstruction removal device, in particular to a root canal obstruction removal device that can remove foreign bodies blocked in the pulp cavity. Background technique [0002] Early dentists often encountered root canal file breaks in the pulp cavity when performing root canal treatment on patients. Generally, it was necessary to enlarge the tooth cavity to remove foreign bodies. However, this would cause the tooth to be treated in the root canal. Later, it is prone to damage and cracks. [0003] For this reason, for example, US Patent No. 5879160 "Root canal obstruction removal system" discloses an 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 an inner cavity 911 and an opening 912 is formed at one end of the sleeve 91. The sleeve 91 is adjacent to the An object opening 913 is prov...

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
