Embodiment Construction

[0013] As shown in the figure: the impact device is composed of a sliding rod 1 and a sliding hammer 2, and the lower clamping device is a clamping cross connection composed of a female piece 5 and a male piece 6. The distal ends of the female piece 6 and the male piece 5 are connected by a The stretching angle of the two pieces is controlled by the telescopic screw force device. The distal end of the male plate 5 forms a movable joint with the force device. The distal end of the female plate 6 is annularly sleeved on the thread of the force device. There is a nut 7 on the outside of the thread to rotate. It can move freely on the screw rod 8 of the force applying device. When the nut 7 rotates from one section to the other section of the force applying device, it pushes the female piece 6 sleeved on the screw rod 8 to move to the male piece 5, so that the ends of the two pieces are tightened. . The force device between the two distal ends is composed of two parallel rods 3, o...

Description

technical field [0001] The invention belongs to the field of medical instruments in the department of prosthodontics, and in particular relates to a metal stud removal device suitable for oral fixed denture restoration. Background technique [0002] Dental nerves cannot be preserved due to factors such as caries and trauma, and root canal therapy is required. The so-called root canal therapy (root canal therapy) is the most commonly used effective treatment method for pulp disease and periapical disease in the world. The principle of root canal therapy is to remove most of the infection in the root canal through mechanical and chemical methods, and to prevent the occurrence of periapical lesions or promote the healing of periapical lesions that have occurred by filling the root canal and sealing the crown. After root canal treatment, when the tooth nerve is removed, the blood supply system in the pulp will be lost, and the blood supply will be lost, and the tooth will gradua...
