Deciduous tooth extraction device

Abstract

The invention relates to the technical field of dentistry, and discloses a deciduous tooth extraction device which comprises a handle and a clamping mechanism installed at one end of the handle, the clamping mechanism comprises two clamping blocks and a driving part used for driving the two clamping blocks oppositely or separately, and pressure sensors are arranged on the two clamping blocks; at least two groups of binding ropes for binding the side edges of the deciduous teeth are connected between the interiors of the two clamping blocks. According to the deciduous tooth extraction device, the two clamping blocks can be driven to clamp and fix the inner side and the outer side of a deciduous tooth through the driving piece, the at least two groups of binding ropes can be synchronously driven to tighten, the two clamping blocks can be matched to wrap and fix the tooth in all directions through the contraction of the at least two groups of binding ropes, and the deciduous tooth extraction device has a multi-layer fastening function; and by arranging two clamping blocks, a worker can conveniently and better insert a binding rope into a gap between teeth, so that the operation convenience is further improved.
