Abstract

The invention belongs to the field of medical equipment, in particular to a device for removing metal studs in dental prosthetics. The existing metal stud removal equipment needs manual operation, and manual hand-held instruments are difficult to stabilize the position directly, and the position is prone to shift, which is harmful to patients. The damage is very serious, the following scheme is proposed, which includes a support frame, a fixing groove is opened on the top of the support frame, a threaded rod is slidably installed in the fixing groove, a drive nut is threaded on the threaded rod, and the top of the threaded rod A mounting plate is fixedly installed, and an adjustment slot is opened on the top of the installation plate, and an adjustment column is installed rotatably in the adjustment slot, and a connection slot is opened at one end of the adjustment column, and a telescopic column is slidably installed in the connection slot. The invention has reasonable structure and convenient operation. The removal device can automatically remove the metal studs, and can stabilize the position during the removal, is less prone to position deviation, and causes less harm to patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for removing metal studs in the Department of Dental Restoration. Background technique [0002] The post crown is a full crown restoration that uses a metal post crown to insert into the root canal to obtain retention. The length of the post crown should be sufficient, generally requiring 2 / 3 to 3 / 4 of the root length, or about the same as the completed root canal. The crown is equal in length, and the thickness of the post crown is about 1 / 3 of the transverse diameter of the root surface. It is conducive to retention. Sometimes the patient needs to take out the old metal post for treatment. The metal post is generally very firmly combined and has a high hardness, so it cannot be directly drilled and ground; [0003] However, the existing metal stud removal equipment requires manual operation. It is not easy to stabilize the position when the manual hand-held in...
