Abstract
The invention discloses a pair of arch wire tail end bending pliers. The front ends of pliers handles extend to form clamping arms. The front ends of the clamping arms are provided with pliers beaks which are adjustable in angle and can be assembled and detached. The pliers beaks include the upper pliers beak and the lower pliers beak arranged on the two clamping arms respectively. The edge parts of the upper pliers beak and the lower pliers beak are opposite. A bending pressure edge and a limiting edge are arranged on the edge part of the upper pliers beak in parallel. The height of the bending pressure edge is larger than that of the limiting edge. A fulcrum edge is arranged on the edge part of the lower pliers edge. When the pliers handles are folded together completely, the fulcrum edge is inserted in a gap between the bending pressure edge and the limiting edge, and the pressure connecting face of the fulcrum edge is located between the pressure connecting face of the bending pressure edge and the pressure connecting face of the limiting edge. When the tail end of an arch wire is bent, the passive traction effect on the arch wire can be effectively relieved, and meanwhile the adverse stress effect conducted to an adhesion component on the tooth face is eliminated. More flexible operability is provided for orthodontics doctors, the vision is widened, and pains and fatigues of patients are reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, especially relate to a kind of arch wire end and bend pincers.
Background technology
Orthodontics belongs to a stomatologic branch, mainly studies the Etiologic Mechanism of malocclusion, diagnostic analysis and prevention and therapy.Dental instrument is the various small portable instruments used in stomatology.In clinical practice, arch wire end needs to carry out bending to prevent arch wire from misplacing and moves and puncture buccal mucosa.Generally, orthodontist usually adopts light wire pliers, youngloop bending pliers etc. to carry out bending operation, these tongers do not belong to the proprietary instrument of bending end arch wire, within the scope of the opening angle in limited patient oral cavity, use underaction facility, in bending process, the passivity pull effect formed for arch wire very easily causes the component be bonded on the flank of tooth to come off by Stress Transfer, also can increase pain sensation and feeling of fatigue to patient simultaneously.
The applying date is on August 16th, 2012, and the day for announcing is disclose a kind of mouth cavity orthodontic arcuate line end back bending pincers in the Chinese patent document on October 9th, 2013, and comprise clamp handle and binding clip, the end of described binding clip is provided with pincers beak, and described pincers beak becomes an angle of 90 degrees with binding clip.This back bending pincers are when clinical manipulation, arch wire end is vertically clamped by pincers beak, rotate the back bending that clamp handle realizes arch wire, in back bending process, passivity is pulled the stress that arch wire produces and brings harmful effect by the component be bonded on the flank of tooth by pincers beak, easily causes arch wire to misplace simultaneously and increases pain sensation to patient.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, technical problem to be solved is to provide a kind of arch wire end and bends pincers, it is by special pincers beak structural design, in the process of bending arch wire end, effectively can alleviate the passivity pull effect caused for arch wire, and eliminate conduction to the undesirable stress effect of the adhesive member on the flank of tooth simultaneously.And, by clamping the adjustable at the angle of inclination of beak, for orthodontist provides operability more flexibly in narrow and small oral cavity space, widening angular field of view, reducing patient oral cavity and opening amplitude, reduce pain sensation and the feeling of fatigue of patient.
The present invention makes above-mentioned technical problem be solved by the following technical programs.
Arch wire end bends pincers, comprise the clamp handle be hinged together, the front end of clamp handle is extended clamping limb, clamping limb front end arranges adjustable tilt angle and detachable pincers beak, pincers beak comprises and point to be located at upper pincers beak on two clamping limbs and lower pincers beak, the cutting edge portion of upper pincers beak and lower pincers beak is arranged in opposite directions, the cutting edge portion of upper pincers beak be arranged in parallel curved pressure seamed edge and spacing seamed edge, the height of curved pressure seamed edge is greater than spacing seamed edge, the cutting edge portion of lower pincers beak arranges fulcrum seamed edge, time completely closed between clamp handle, fulcrum seamed edge inserts the gap between curved pressure seamed edge and spacing seamed edge, the electrolysis of fulcrum seamed edge is between curved pressure seamed edge electrolysis and spacing seamed edge electrolysis.
The pincers beak that this arch wire end bends pincers has special structural design, the cutting edge portion of upper pincers beak is provided with curved pressure seamed edge and spacing seamed edge, the cutting edge portion of lower pincers beak is provided with fulcrum seamed edge, during bending arch wire end, in closed clamp handle process, matched by curved pressure seamed edge and fulcrum seamed edge and merge with fulcrum seamed edge for press-bending fulcrum carries out arch wire flexing movement, arch wire bears passivity pull effect, to match with spacing seamed edge through fulcrum seamed edge and oppositely crimp arch wire, slow down and offset the active force that arch wire passivity bears pulling, and stop pulling stress to the adhesive member conduction on the flank of tooth, eliminate the harmful effect.Pincers beak can adjust angle of inclination and can install and remove flexibly, increases the motility of orthodontist operation, widens observation visual angle, and that can reduce patient oral cavity opens amplitude simultaneously, reduces pain sensation and the feeling of fatigue of patient.
As preferably, clamping limb front end is provided with open slot, and pincers beak is provided with the projection matched with open slot, and pincers beak is fixed on clamping limb by trip bolt cross-under projection.Such fixed connection structure is simply compact, and install and remove easy to adjust, manufacture difficulty is low.
As preferably, clamping limb is arranged concave arc moulding surface structure.Be conducive to the angular field of view widening orthodontist, increase operating flexibility, reduce and wipe the probability of touching with face.
As preferably, between clamp handle, stage clip is set.Under off working state, remain between upper pincers beak and lower pincers beak and open, easy to use.
As preferably, clamp handle, clamping limb and pincers beak are stainless steel structure.By force corrosion-resistant, popularization and application is good.
As preferably, clamp handle and clamping limb are one of the forming structure.Easy to make, technique is simple.
Generally speaking, arch wire end of the present invention bends pincers by the optimal design to pincers beak structure, make when arch wire bending operation, slow down and offset the active force that arch wire passivity bears pulling, and stoping pulling stress to the adhesive member conduction on the flank of tooth, the phenomenon that elimination adhesive member comes off by undesirable stress effect occurs.Meanwhile, pincers beak can adjust angle of inclination and can install and remove flexibly, not only can increase angular field of view during orthodontist operation, convenient observation, be increased in the motility of narrow and small mouth transluminal operation, and without the need to the excessive mouth open angle of patient, reduce the pain sensation of patient and tired sense of discomfort.
Accompanying drawing explanation
