Continuous traction hook pincers

Abstract

The invention relates to continuous traction hook pincers which comprise an upper pincer and a lower hook, wherein the upper pincer comprises an upper pincer handle and an upper pincer head; the lower pincer comprises a lower pincer handle and a lower pincer head; the upper pincer head is wrapped outside the lower pincer head; a turnover cover is arranged on the upper pincer head; a draw pincer box is arranged on the upper pincer head; the traction hook pincer box comprises a box bottom, a sliding track, a spring and a box wall; the box bottom is arranged at the bottom inside the upper pincer head; the box wall is arranged along a side wall of the upper pincer head; the sliding track is arranged at the upper part of the box bottom, is arranged along the box wall and is a circular arc shaped track; the head arranged on the upper pincer head, of one end of the sliding track is used as a draw pincer outlet; a spring is arranged at the other end of the sliding track. By adopting the continuous traction hook pincers provided by the invention, traction hooks do not need to be frequently loaded, and a next traction hook can be automatically loaded after a former one is clamped. An inclined forcing ridge is designed in a forcing position of a pincer head, and different from a vertical forcing ridge, the inclined forcing ridge is capable of preventing an arch wire from easily deformation. The traction hook box can be disassembled and can be easily sterilized; rubber sleeves are adopted for assistant storage of the traction hooks, and thus the traction hooks can be conveniently loaded.

Description

technical field [0001] The invention belongs to the technical field of oral medical instruments, and relates to a continuous firing type traction hook forceps. Background technique [0002] Deformities of teeth, jaws, and craniofacial caused by prior and acquired factors need to be corrected by orthodontic treatment, and traction hooks are used in orthodontic treatment as an important component for applying orthodontic force. The traditional traction hook clamp can only hold one traction hook at a time, and the traction hook needs to be loaded before clamping, which is very inconvenient to use. Moreover, after clamping the traction hook, the arch wire is easily deformed and bent, which affects the orthodontic effect. Clinically, it is often necessary to fix the traction hook on the arch wire, and hang a rubber chain or a ligation wire on it. The fixation step needs to be completed by the traction hook pliers, and the metal sheet on the traction hook is wrapped and stuck on ...
