Abstract

The invention relates to pull-out devices, in particular to an orthopedics broken nail pull-out device. The orthopedics broken nail pull-out device is characterized in that the power can be controlled, and the device is provided with assistance and kept in a certain angle. According to the technical scheme, the orthopedics broken nail pull-out device comprises a circular mounting plate, clamping plates, guide sleeves, guide rods, running pulleys, arc bolts, a first nut and the like; the clamping plates are rotatably connected with the left and right sides of the bottom of the circular mountingplate, arc grooves are formed in the upper portions of the left and right sides of the clamping boards, the guide grooves are formed in the left and right sides of the lower portion of the circular mounting plate, the guide sleeves are arranged on the left and right sides of the circular mounting plate, the guide rods are connected with the interiors of the guide sleeves, and the lower portions of the guide rods are located in the guide grooves. Through the arrangement of the guide rods, when a person moves the first nut downwards, the guide rods can be driven to move downward so that the clamping plate on the left side can move relative to the clamping plate on the right side, and thus a broken nail is clamped; through the arrangement of an arc connection rod and ab assistance rod, the person can hold the arc connection rod.

Description

technical field [0001] The invention relates to a device for taking out broken nails, in particular to a device for taking out broken orthopedic nails. Background technique [0002] Orthopedics is one of the common departments in the hospital. Orthopedic patients usually need to screw in screws in the bone during treatment. Therefore, when the screws are taken out by the patients, the nails often break. At present, people mainly use tweezers to clamp the screws, and then manually pull them out. Rotating and pulling out the screw, because the amount of force cannot be guaranteed when dialing out by hand, it is easy to cause additional damage; during this process, the doctor only uses both hands to control the tweezers, and there is no other assistance to maintain the angle of nail removal, resulting in slower nail removal. Contents of the invention [0003] In order to overcome the disadvantages that it is difficult to control the strength of the screw by hand, and it is di...
