Abstract

The invention discloses an orthopedic nail taking device convenient for taking out broken nails. The device comprises a supporting plate. Connecting rods are fixedly connected to the left side and theright side of the lower surface of the supporting plate. The connecting rods are arranged in a limiting groove. The bottom ends of the connecting rods are fixedly connected with a sliding plate. Theleft end and the right end of the sliding plate are respectively in sliding connection with sliding grooves which are formed in the left side surface and the right side surface of the inner wall of the limiting grooves in a sliding mode. The orthopedic nail taking device is provided with a feeding device. A downward pressure can be applied to a spring through the connecting rods when a screw tap moves downwards. The spring is compressed, so that the spring can exert an upward elastic force on the connecting rods under the action of the pressure. As a result, the screw tap can exert an upward pulling force on a broken nail in the process of forming an internal thread until the broken nail is separated from a bone. Therefore, a round groove can be prevented from being formed in the peripheryof the broken nail in the nail taking process. In this way, a fracture part can be prevented from being damaged again.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic nail remover for easy removal of broken nails. Background technique [0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has undergone significant changes. For example, bone and joint tuberculosis, osteomyelitis, polio and other diseases have decreased significantly, and trauma caused by traffic accidents has increased significantly. [0003] In fracture surgery, fixation plates and steel nails are usually used to fix the fracture site. The steel nails need to be removed after being implanted in the human body for a period of time. Because the steel nails th...
