Broken nail taking-out assisting device

Abstract

The invention provides a broken nail taking-out assisting device. The broken nail taking-out assisting device comprises a fixing sleeve and a fixing head, wherein the fixing sleeve is rotationally connected with the fixing head, the end of the fixing head is provided with a twisting rod, the fixing sleeve is slidably provided with a sliding plate, the twisting rod penetrates through the sliding plate, and when the sliding plate moves along a sliding sleeve, the fixing head can be driven to rotate through the twisting rod. The broken nail taking-out assisting device achieves the purpose of taking out broken nails by arranging the rotatable fixing head with the twisting rod and the sliding plate driving the twisting rod to rotate and controlling the sliding plate to move to drive the twisting rod to rotate and accordingly drive the fixing head to rotate. In conclusion, the broken nail taking-out assisting device has the advantages that the structure is reasonable, the operation is convenient, time and labor are saved, the improvement of the working efficiency is facilitated, the rotation speed of the fixing head is completely controllable, and the device is suitable for popularization and application.

Description

technical field [0001] The invention relates to an auxiliary device for taking out broken nails. Background technique [0002] In the trauma treatment of fracture patients, broken screw or ordinary screw fixation is often used clinically. According to the fracture site, different angles, screws, and numbers are selected for fixation. After the fracture is fixed, the patient often recovers during treatment. There will be a phenomenon that the screw breaks. How to take out the broken screw while minimizing the damage to the fractured patient is a difficult problem. [0003] The patent document with the application number CN201520274654.3 discloses an auxiliary device for removing broken nails, which includes a cylinder with milling teeth. The end of the cylinder away from the milling teeth is provided with a triangular column. After the broken nails are fixed with the cylinder, an electric drill Or the handle is installed on the triangular column to rotate so that the broken...

[0003] The patent document with the application number CN201520274654.3 discloses an auxiliary device for removing broken nails, which includes a cylinder with milling teeth. The end of the cylinder away from the milling teeth is provided with a triangular column. After the broken nails are fixed with the cylinder, an electric drill Or the handle is installed on the triangular column to rotate so that the broken nail is taken out. This operation has the following defects: when rotating with the handle, one hand needs to hold the cylinder, and the other hand rotates the handle, which is slow to rotate, which is not conducive to improving work efficiency; , due to the heavy weight of the electric drill, the operation is more inconvenient, and the rotation speed of the electric drill is stable during the nail removal process, it is not suitable to control in case of an emergency, and it is easy to cause harm to the patient
