Metal pile nail removing device for dental restoration department

Abstract

The invention belongs to the field of medical apparatus and instruments, and particularly relates to a metal pile nail removing device for the dental restoration department. Existing metal pile nail dismantling equipment needs to be operated manually, the position is not easy to stabilize, position deviation is easy to occur, and the harm to a patient is very large due to the fact that the equipment is manually held by hand for direct hard pulling. In order to solve said problems, the scheme provides that the device comprises a supporting frame; a fixing groove is formed in the top of the supporting frame, a threaded rod is slidably mounted in the fixing groove, a driving nut is mounted on the threaded rod in a threaded mode, a mounting plate is fixedly mounted at the top end of the threaded rod, an adjusting groove is formed in the top of the mounting plate, an adjusting column is rotatably mounted in the adjusting groove, a connecting groove is formed in one end of the adjusting column, and telescopic columns are slidably mounted in the connecting grooves. The invention is reasonable in structure and convenient to operate, the metal pile nail can be automatically removed through the removing device, the position can be well stabilized during removing, position deviation is not prone to occurring, and harm to a patient is small.

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...
